圖1是根據本發明的具體實施例之使用薄層來判斷是 否有接觸之面板的剖面圖。參考圖1，面板包含具有複數個 光學感測器103之光學感測器陣列層丨〇〇、第一基板j i、 第二基板102、接觸檢測層1〇4以及介電層1〇5。 光學感測器陣列層丨〇〇安置於第二基板1 〇2的上方。 8 201005607 在本具體實施例中，光學感測器1〇3介在第一基板ι〇ι和 第二基板102之間（但’本發明不限制於此），也有複數 個薄膜電晶體，且各種顯示裝置可以介在第一基板1〇1和 第二基板102之間。第一基板1〇1和第二基板1〇2可以由 玻璃、金屬或塑膠所形成。雖然未顯示在目前的具體實施 例中，光學感測器陣列層100可以包含複數個電極，其構 成薄膜電晶體（TFT )層（舉例來說’半導體層和隔離層） #和有機發光設備。有機發光設備包含像素電極、面對像素 電極的相反電極、包含發光層的中間層，該發光層介於像 素電極（舉例來說’陽極）和相反電極（舉例來說，陰極 電極）之間。 當特定物體（舉例來說，手指107 )接觸面板，則光學 感測器103藉由解譯從光源所產生的手指1〇7的陰影影像 而計算接觸面板的位置座標，藉由解譯光總量而產生二元 影像（binary image )，且從二元影像解譯接觸面板的位置 • 座標’或藉由解譯從内部光源所反射的光總量而產生二元

中，如上所述，在藉由使用接觸檢測層1〇4而具有顯示資 訊在螢幕上的功能之顯示裝置中，是否有接觸是可以藉由 檢測電容改變而判斷，電容改變是由接觸而造成於接觸檢 測層104中，而不需使用光學感測器1〇3來解譯所擷取的 影像。舉例來說，可以跳過複雜的影像解譯過程，其中檢 測了邊緣，計算是否有邊緣從其他邊緣移動到不同方向， 且基於計算結果而判斷是否有接觸。因此，光學感測器 可以個別地計算接觸位置的座標❿：^解譯所㈣的影 像。在此，如果藉由接觸檢測層1〇4所檢測的電容值是小 於或大於飽和電容值（舉例來說，預定飽和電容值），則 主機或接觸判斷模組判斷例如手指1〇7的接觸。替代性地， 當光學感測器103計算接觸位置時，用來執行判斷接觸位 置的座標之計算的量可以藉由使闕於接觸檢測層ι〇4所 檢測的接觸之資訊而減少。 在使用光而具有顯示f訊在螢幕上的功能之傳統的晶

因而降低中央處理單元（CPU)的計算總量和記憶體的負 載》又’可以減少（或避免）由物體的陰影所造成的錯誤 感測，該錯誤感測t可能發生於傳統影像分析方法。 介電層105形成在接觸檢測層1〇4之上，且減少或避 免了外部自然光射入發光顯示裝置或光學感測《1〇3的上 方，或從該處反射外部自然光。如果需要的話，可以省略 介電層105。 圖2是透視圖和剖面圖，其藉由使用圖1的接觸檢測

Description of the Invention: [Technical Field] The present invention relates to a display device having a function of inputting information by an optical sensor. [Prior Art] Traditionally, a mouse or a keyboard is used to supply an input signal to a computer. In addition, the remote control is used to allow the user to select a specific function in the digital television (τν). However, when the user is not accustomed to manipulating the input device, the user may have difficulty using the input device (for example, a mouse, a keyboard, or a remote control). Touch panels or touch screens are innovative input devices that have been developed to remove the aforementioned difficulties. The touch screen allows the user to input command signals by directly touching the display panel with the user's finger or pen, without using, for example, a mouse. Therefore, a user who has difficulty using an input device (for example, a mouse or a keyboard) can use a digital device (for example, a computer) without difficulty by directly touching the display panel with, for example, his/her finger. ). The touch panel can be sorted according to the method of sensing external input. For example, touch panels can be categorized into the use of electrostatic capacitance, the use of resistive layers, the use of ultrasonic waves, the use of a holistic approach to measuring tension, the use of piezoelectric effects, and the use of optical sensing touch panels. In particular, in a touch panel using optical sensing, for example, the contact performed by the user's finger is sensed by forming a photodiode in the panel, and the current is sensed, and the current is borrowed. Produced by light incident on the photodiode 201005607. The photodiode is a one-dimensional strain, and the component is necessary for a touch panel that can be easily manufactured, so the component can be manufactured in a program for forming a driving circuit of the display panel, for example. Said, liquid crystal display (LCD), organic light-emitting diode (〇 LED). However, for the conventional method of sensing light, it is difficult to break the object (for example, the user's finger or the light pen) A and to calculate the coordinates of the object. And 'for the traditional method, the disadvantage is that it will cause erroneous sensing due to the shadow of the object and consume a lot of power in the optical sensor scanning circuit operation (whether or not the contact is carried out by a specific object) and the circuit (Used to read the sensed signal). SUMMARY OF THE INVENTION A concept of a specific embodiment of the present invention indicates that a display device having a function of displaying information on a screen by using light can not only judge whether or not there is contact using an additional device (and does not have to interpret it) The captured image), and the position of the contact can be judged by using an optical sensor.

BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a cross-sectional view of a panel using a thin layer to determine whether there is contact, in accordance with an embodiment of the present invention. Referring to Fig. 1, the panel includes an optical sensor array layer 具有 having a plurality of optical sensors 103, a first substrate j i , a second substrate 102 , a contact detecting layer 1 〇 4 , and a dielectric layer 1 〇 5 . The optical sensor array layer is disposed above the second substrate 1 〇2. 8 201005607 In this embodiment, the optical sensor 1〇3 is interposed between the first substrate ι and the second substrate 102 (but 'the invention is not limited thereto), and there are also a plurality of thin film transistors, and various The display device may be interposed between the first substrate 1〇1 and the second substrate 102. The first substrate 1〇1 and the second substrate 1〇2 may be formed of glass, metal or plastic. Although not shown in the present detailed embodiment, optical sensor array layer 100 can comprise a plurality of electrodes that form a thin film transistor (TFT) layer (e.g., 'semiconductor layer and isolation layer) # and an organic light emitting device. The organic light-emitting device includes a pixel electrode, an opposite electrode facing the pixel electrode, and an intermediate layer including a light-emitting layer interposed between the pixel electrode (for example, an anode) and an opposite electrode (for example, a cathode electrode). When a specific object (for example, the finger 107) contacts the panel, the optical sensor 103 calculates the position coordinates of the touch panel by interpreting the shadow image of the finger 1 〇 7 generated from the light source, by interpreting the total light Generates a binary image and interprets the position of the contact panel from the binary image • coordinates or generates a binary image by interpreting the total amount of light reflected from the internal light source and calculates the position of the contact panel coordinate. The optical sensor 103 can be a PIN type photodiode. The contact detecting layer 104 is interposed between the first substrate 1〇1 and the dielectric layer 1〇5 and is formed using a transparent film layer to increase the transmittance of light, thereby reducing (or avoiding) the performance degradation of the display device. Also, the contact detecting layer 104 may be embedded in the panel substrate during the manufacture of the panel, or additionally formed on the panel substrate. If the finger 107 touches or touches the panel, the contact detecting layer 1〇4 detects a change in capacitance caused by the finger 107. In this case, contact 9 201005607 detects layer 104 and the panel forms a capacitor. In the present embodiment, the contact detecting layer 104 and the cathode electrode under the first substrate 101 form a capacitor. Here, the cathode electrode comprises an organic light-emitting device included in the optical sensor array layer 100. Therefore, it is not necessary to form an additional electrode or layer to form a capacitor together with the contact detecting layer 104. In the present embodiment, as described above, in the display device having the function of displaying information on the screen by using the contact detecting layer 1〇4, whether or not the contact can be judged by detecting the capacitance change, the capacitance The change is caused by contact in the contact detecting layer 104 without using the optical sensor 1〇3 to interpret the captured image. For example, a complex image interpretation process can be skipped in which edges are detected, whether edges are moved from other edges to different directions, and whether or not there is contact based on the calculation result. Therefore, the optical sensor can calculate the coordinates of the contact position ❿: ^ Interpretation (4). Here, if the capacitance value detected by the contact detecting layer 1〇4 is less than or greater than the saturation capacitance value (for example, a predetermined saturation capacitance value), the host or the contact determination module determines, for example, the contact of the finger 1〇7. . Alternatively, when the optical sensor 103 calculates the contact position, the amount of calculation for performing the coordinates determining the contact position can be reduced by the information of the contact detected by the contact detecting layer ι4. In a conventional crystal display device that uses light to display the function of the signal on the screen, the edge is detected from the captured image, and the detected edge is used to determine whether the object touches the screen. That is, the direction of the edge is detected and when the edge is moved in a different direction than the other edges, the object is a screen. If it is judged that the object touches the curtain, then the coordinates of the contact position are obtained by calculating the center of gravity of the edge moved to the edge of 2010-05607. However, according to the conventional embodiment of the present invention, it is easier to judge whether an object (especially a finger) touches the screen by using the contact detecting layer, thereby reducing the total calculation of the central processing unit (CPU). The amount and load of the memory "can" reduce (or avoid) the error sensing caused by the shadow of the object, which may occur in conventional image analysis methods. The dielectric layer 105 is formed over the contact detecting layer 1〇4, and reduces or avoids the exposure of external natural light to the upper side of the light-emitting display device or the optical sensing “1〇3, or the external natural light is reflected therefrom. Dielectric layer 105 can be omitted if desired. Figure 2 is a perspective view and a cross-sectional view explaining the formation of the electric grid by using the contact detecting layer of Figure 1. Referring to Fig. 2, the contact detecting I 104 in contact with the finger 107 functions as an electrode of the capacitor, and the cathode electrode 106 formed under the first substrate 101 functions as the other electrode of the capacitor, wherein the other electrodes are opposite to each other. Therefore, the contact detecting layer (10) and the cathode electric power = 106 form a capacitor 'and measure the electric power caused by the contact of the finger 1G7: change? . In another embodiment f of the present invention, if an organic light-emitting device is shown, no additional electrodes/layers are required to form a capacitor from contact 04 because of the organic inclusion in the optical sensor array layer 100. A cathode electrode 106 of the illuminating device is formed below the first substrate to cover, for example, completely cover the bottom of the first substrate 101. 修改A modified panel of the panel illustrated in accordance with the present invention A cross-sectional view of a specific embodiment. Referring to FIG. 3, the panel includes an optical sensor array layer 1 having a plurality of optical 11 201005607 sensors 103, a first substrate 1 〇1, a second substrate 102, and a first contact The detection layer 1 〇8, the second contact detection layer 丨〇9, and the dielectric layer 105. The panel illustrated in Fig. 3 is the same as the panel of Fig. 1 except for the first contact detection layer 108 and the second contact detection layer 109. Therefore, the same reference numerals as in Fig. 1 denote the same elements, and their operation or characteristics will not be repeated. The panel of circle 3 will now describe these differences. The second contact detecting layer 109 is formed in Above a substrate 101, and a first contact detecting layer 108 is formed over the second contact detecting layer 1 〇 9. D The first contact detecting layer 108 and the second contact detecting layer 109 form a capacitor and detect contact by the finger 107 The resulting capacitance changes. As shown in Figure 3, there is a space 105 ' between the first contact detecting layer 108 and the second contact detecting layer 丨〇 9. The space 1 〇 5 ' can be a dielectric material (for example, The predetermined dielectric material is filled. Although the invention has been described in the above specific embodiments with respect to the organic light-emitting device, it is obvious to those skilled in the art that the present invention can be applied to other forms of flat panel display devices ( For example, liquid crystal display (LCD) or plasma display panel (pDp), as long as they can be used to determine the device for inputting information using an optical sensor. Figure 4 is a diagram of Figure 1 in accordance with the present invention. A cross-sectional view of another modified embodiment of the illustrated panel. Referring to Figure 4, the panel includes an optical sensor array layer 1 , a substrate ιοί, having a plurality of optical sensors 1 〇 3 a substrate 102, the first The contact detecting layer 11A, the second contact detecting layer πι, and the dielectric layer 105. The panel illustrated in FIG. 4 is the same as the panel of FIG. 1 except for the first contact detecting layer 11A and the second contact detecting layer 111. 201005607 Same as. Therefore 'the same component symbols as ® 1 represent the same components and will not repeat their operation or characterization. The panel of 4 will now state these differences. Refer to Figure 4 'First Contact The detection layer 110 is formed over the first substrate 101, and the second contact detection layer ill is formed under the first substrate 101. The first-contact detection &"〇 and the second contact detection layer" And detecting the change in capacitance due to the finger touching the panel. 5A, 5B, and 5C are cross-sectional views of a panel using a thin layer to determine whether or not there is contact, in accordance with other embodiments of the present invention. In the previous embodiment described with reference to Figures 1 through 4, one or two contact detection layers are used to detect capacitance? In the present embodiment, the dielectric constant or dielectric change between the contact detecting layers is used to detect a change in capacitance. Since &, according to the pressure applied by the finger contact, it is possible to easily judge whether or not the finger is in contact by measuring the change in the dielectric constant or the interval between the contact detecting layers without requiring an optical sensor. Again, this can reduce or avoid erroneous sensing caused by shadows of non-finger objects' which are more likely to occur in conventional image interpretation methods. The position coordinates of the finger contact are calculated using an optical sensor, as in the previous specific embodiment described with reference to Figures 1-4. Referring to FIG. 5A, the panel includes an optical sensor array layer 1 having a plurality of optical sensors 1〇3, a first substrate 1〇1, a second substrate 1〇2, a first contact detecting layer 112, and a second The detection layer 113, the dielectric layer 4, and the dielectric layer 105 are contacted. The first contact detecting layer 112 is located below the first substrate 1〇1, and the 13 201005607 second contact detecting layer 113 is spaced apart from the first contact detecting layer ι2, which may be a reservation. The space between the first contact detecting layer ι2 and the second contact detecting layer 113 may be filled with the dielectric U4. In the particular embodiment, dielectric 114 is a material that changes the dielectric constant or spacing depending on the pressure applied thereto. When the finger 107 contacts the panel, the dielectric constant or interval between the first contact detecting layer 112 and the second contact detecting layer U3 changes depending on the pressure of the panel to which the finger ι 7 contacts. Therefore, whether or not the panel is touched can be easily judged by detecting a change in dielectric constant or interval between the first contact detecting layer 112 and the second contact detecting layer 丨丨3. Figure 5B is a cross-sectional view of a modified example of the panel of Figure 5A in accordance with the present invention. Referring to FIG. 5B, the panel includes an optical sensor array layer 100 having a plurality of optical sensors ^3, a first substrate 1, a second substrate 102, a first contact detecting layer 115, a second contact detecting layer 116, Dielectric 117 and dielectric layer 105. The panel illustrated in Fig. 5B is different from the panel of Fig. 5A in terms of the position of the first contact detecting layer 115 and the second contact detecting layer 116. The same reference numerals as in Fig. 1 and Fig. 5A denote the same elements' and their operation or characteristics will not be repeated. The panel of Figure 5B will now describe these differences. The second contact detecting layer 116 is located under the first substrate 101, and a dielectric is applied to the first substrate 101. The first contact detecting layer 115 is formed over the dielectric 117. When the finger 107 contacts the panel, the dielectric constant 7 (below the first contact 14 201005607 touch detection layer 115) or the interval between the first contact detecting layer 115 and the > contact detecting layer 116 changes. Therefore, whether or not the panel is touched can be easily judged by detecting a change in dielectric constant or interval between the first contact detecting layer 115 and the second contact detecting layer ι6. Reference Figure π is a cross-sectional view of another modified example of the panel of Figure 5A in accordance with the present invention. Referring to FIG. 5C', the panel includes an optical sensor array layer i 具有 having a plurality of optical sensors 103, a first substrate Xia, a _ substrate 1, 2, a first contact detecting layer 118, and a second contact detecting. Layer ιι9,: Electrode 120 and dielectric layer 1 () 5. In terms of the positions of the first contact detecting layer ι 8 and the second contact detecting layer U9, the panel shown in Fig. 5A is different from the panel of Fig. 5A. With the map! The same reference numerals as in Fig. 5-8 denote the same elements, and their operation or characteristics will not be repeated. The panel of Figure 5c will now describe these differences. The second contact detecting layer 119 and the first contact detecting layer 118 are sequentially formed on the first substrate 1 (1) in sequence, and the space between the first contact detecting layer 118 and the second contact detecting layer 119 can be interposed. The electricity is 12 inches to fill up. When the finger 107 contacts the panel, the dielectric constant (below the first contact detecting layer 118) or the interval of the dielectric 12 在 between the first contact detecting layer 118 and the second contact detecting layer 119 is changed. Therefore, whether or not the panel is touched can be easily judged by detecting a change in the dielectric constant or the interval of the dielectric 120 between the first contact detecting layer i 8 and the second contact detecting layer i i 9 . Figure 6 is a cross-sectional view of a panel using a touch film to determine whether a panel is in contact, in accordance with another embodiment of the present invention. Referring to FIG. 6, the panel includes an optical sensor array layer j 〇〇 ' optical sensor 103 having a plurality of optical sensors 1 〇 3, a first substrate 1 〇 1, a second substrate 1 〇 2, and a thin touch 15 201005607 Membrane 121. The touch film 121 is bonded to the top surface of the first substrate 101. The touch film 121 is preferably a transparent conductive film, and the pressure applied by the fingers 1 〇 7 becomes an electrical signal. The touch film 121 preferably has characteristics such as low surface resistance, high light transmittance, high adhesion characteristics, smooth surface, and heat resistance. Generally, transparent conductive films are classified into a transparent film having conductivity and a transparent film coated with a conductive material. The base film of the transparent conductive film may be formed of polyethylene terephthalate resin (ΡΕτ), polyether sulfone (PES), polycarbonate (pC), or polyarylate (pAR). The transparent conductive film may be made of indium tin oxide, tin oxide, Zn bismuth,

The use of the touch film 121 to judge whether or not the panel is touched can be carried out according to a pressure sensitive method, a resistive layer method, and/or a capacitive method. Figure 7 is a cross-sectional view of a panel using a pressure sensor 122 in accordance with another embodiment of the present invention. Referring to Figure 7, the panel includes an optical sensor array layer 1 having a plurality of optical sensors 103. The first substrate 1 〇1, the second substrate 102, and the pressure sensitive sensor 122.压力 The pressure sensitive sensor 122 is disposed below the second substrate 1〇2, and the switching pressure (which is caused by the finger 1〇7 contacting the panel) becomes an electrical signal. Therefore, whether or not the panel is touched can be easily judged by detecting such a signal. The pressure sensitive sensor 丨22 measures the distribution of pressure. If pressure is applied to a portion of the pressure sensitive sensor 122, the resistance value of the pressure sensitive conductive rubber of the pressure sensor 122 may decrease, and therefore, whether the object (especially the finger 107) contacts the panel may detect the pressure sense 16 201005607 Judgement of the resistance value of the detector 1 22 is judged. Figure 8 is a block diagram of a display device having a position information acquisition device 850 in accordance with an embodiment of the present invention. Referring to FIG. 8, the display device includes a display panel 800 having a plurality of optical sensors 810, a contact detecting layer 820 to be bonded or bonded to the display panel 800, and a sensor array for providing scanning signals to each of the optical sensors 810. The driving unit 83A reads the sensor information reading unit 840, α and the position information obtaining device 850 of the data acquired by each of the optical sensors 810. The location information obtaining device 850 includes a contact measuring unit 851, a contact determining unit 852, a signal generating unit 853, and a coordinate calculating unit 854. When a specific object (for example, a 'finger') contacts the display device, each optical sensor 8 10 calculates the position coordinates of the contact by interpreting the shadow image of the finger generated from the natural light source, by interpreting the total light Produce a binary image, and interpret the coordinates of the contact position from the binary image, or generate a binary image by interpreting the total amount of light reflected from the internal light source and calculate the position coordinates of the contact from the binary image . The display panel 800 includes red (R), green (G), and blue (B) pixels, which are disposed with the optical sensor 810 at a point where a plurality of scan lines = a plurality of scan lines are interlaced with each other. The display surface & 8〇〇 is based on the outside. The image is displayed by the image signal received by the host. The contact detecting layer 820 obtains contact information by detecting whether a specific object (especially hand =) contacts the display screen, and provides contact information to the information acquiring device 850. According to the previous embodiment, such contact 2 is clearly defined as capacitance, dielectric constant, spacing, resistance value, and the like. The structure and position of the contact detection 82A are described above with reference to Figures i to 7. 17 201005607 If it is determined that the finger touches the display screen, the sensor array driving unit 830 transmits a scan signal to the display panel 800, the scan signal indicating one of the selected optical sensors 810. The sensor information reading unit 840 reads the signal sensed by the selected optical sensor 810 of the display panel 800 and provides the sensing result to the position information obtaining device 850. The location information obtaining device 850 receives the sensed signal via the sensor information reading unit 840, calculates a coordinate target of the contact position based on the sensed signal, and outputs the calculation result to the external host. Further, the location information obtaining device 850 receives the contact information from the contact detecting layer 820, and controls whether the sensor array driving unit 83 and the sensor information reading unit 840 are to be operated based on the contact information. Specifically, if the finger does not touch the display screen, the position information obtaining device 85 stops the operations of the sensor array driving unit 83 and the sensor information reading unit 840, thereby reducing power consumption or achieving lower power consumption. Alternatively, the operation of the sensor array driving unit and the sensor information reading unit 84 may partially stop rather than all

Specifically, if it is judged that the display screen is not touched, the contact judging unit 852 controls the signal generating unit 853 to generate a signal indicating the operation of the stop sensor array driving unit 83 and the sensor information reading unit 7G 840. Here, the signal can be either logic low or logic high. Under the control of the contact determination unit 852, the signal generation unit 853 generates and outputs a signal to operate the sensor array driving unit 83 and the sensor-before reading unit 84A, or generate and output a signal to stop the sense. The operation of the detector array driving unit 830 and the sensor information reading unit 84A. If the display screen is not touched, the internal circuit operation for calculating the contact position (ie, the operation of selecting the sensor array driving unit 830 and the sensor information reading unit (4) of one of the optical sensing 810) is stopped, Thereby reducing power consumption or achieving lower power consumption. Also, it may be possible to reduce or avoid the false sensing of the device caused by shadows rather than fingers, which may occur in conventional image analysis methods. Figure 9 is a flow diagram illustrating the reduced power consumption and implementation rate of the display device of Figure 8 in accordance with a particular embodiment of the present invention.
