Therefore, users' demand for large-screen teaching, large-screen conferences, large-screen writing and drawing, etc. is also stronger, and then the touch accuracy of display devices And large size also put forward higher requirements.

The capacitive display device works by using the current induction of the human body. By pasting a layer of transparent special metal conductive substance on the glass surface, when a conductive object touches, it will change the capacitance of the contact, so that the touch can be detected. s position. Although the capacitive display device has high touch precision and strong anti-interference performance, it is impossible to realize a display device with a large size and high touch precision. This is because when the touch precision of the capacitive display device is improved, it will increase The touch detection time of the capacitive display device reduces the charging time of the pixels, and the charging time of the remote pixels is insufficient, resulting in color deviation.

In view of this technical problem, the embodiment of the present application provides a screen display method and a display device.

The double need for size.

A screen display method provided by an embodiment of the present application will be described below with reference to FIG. 2 and FIG. 3 .

It should be noted that the first frame is a basic unit of a frame displayed by the display device.

S210. The image processing chip acquires the first picture, divides the first picture along the first direction to obtain the first sub-picture and the second sub-picture, and performs image overlapping on the first sub-picture and the second sub-picture respectively to generate a second sub-picture. The second frame and the third frame, wherein at least a partial overlapping area exists between the second frame and the third frame.

Specifically, the image processing chip receives the first picture, and divides the first picture along the first direction to obtain the first sub-picture and the second sub-picture; Image overlapping is performed on the second sub-picture, and a second picture and a third picture are correspondingly obtained, and there is at least a partial overlapping area between the second picture and the third picture. After that, the image processing chip transmits the second picture and the third picture to the first timing control chip and the second timing control chip respectively, specifically, the image processing chip transmits the second picture to the first timing control chip, and the The third picture is transmitted to the second timing control chip, therefore, the second picture corresponds to the first timing control chip, and the third picture corresponds to the second timing control chip.

It should be understood that the second picture corresponds to the first sub-picture, and the third picture corresponds to the second sub-picture.

It should be understood that the first direction may be a vertical direction or a horizontal direction. At the same time, the process of the image processing chip dividing the first frame along the first direction is equivalent to the process of partitioning and transmitting the first frame by the image processing chip.

It should be understood that the first picture corresponds to a plurality of pixels of the display panel, which can be understood as: the plurality of pixels corresponding to the first picture may be all pixels of the display panel, or may be some pixels. limited.

It should be understood that the overlapping degree of the partial overlapping area between the second picture and the third picture may be 30%, may be 50%, or may be 100%. The degree of image overlap is not specifically limited.

It should be understood that the degree of picture overlap refers to the proportion of the overlapped picture area in the original picture. When the picture overlap is 100%, it means that the second picture and the third picture are equivalent pictures, that is, the first picture, the second picture The second picture and the third picture are exactly the same picture (both are the first picture).

As a possible implementation, if the image overlapping area between the second picture and the third picture is 100%, then the second picture is equal to the first picture, the third picture is equal to the first picture, then the second picture and the first picture The picture overlapping area between the three pictures is the whole content of the first picture.

Exemplarily, the first picture corresponds to 3840 (columns) * 2160 (rows) pixels, then the image processing chip divides the first picture into the first sub-picture and the second sub-picture, and the first sub-picture corresponds to 1920 (columns) * 2160 (row) pixels, the second sub-picture corresponds to 1920 (column)*2160 (row) pixels. The image processing chip performs image overlapping on the first sub-picture and the second sub-picture respectively to generate the second picture and the third picture, and stipulates that the overlapping picture area between the first sub-picture and the second sub-picture corresponds to 1920 (columns) *2160 (row) pixels, therefore, the second picture corresponds to 3840 (column)*2160 (row) pixels, and the third picture corresponds to 3840 (column)*2160 (row) pixels.

The partition transmission shown in FIG. 2 will be further described below in conjunction with FIG. 3 .

Fig. 3 is a schematic diagram of partition transmission provided by an embodiment of the present application. Specifically as shown in Figure 3, the image processing chip of the display device divides the area that needs to display the first picture into two partitions, and the left and right partitions transmit two sub-pictures respectively (that is, the left partition corresponds to the first sub-picture, and the right sub-picture corresponds to the first sub-picture). partition corresponds to the second sub-picture). Each partition corresponds to 1920 (columns) * 2160 (rows) pixels, and the overlapping picture area is set to correspond to 1920 (columns) * 2160 (rows) pixels, so that the pixels corresponding to the second picture actually transmitted by the left partition are non-overlapping picture areas The sum of the corresponding 1920 (column)*2160 (row) pixels and the 1920 (column)*2160 (row) pixels corresponding to the overlapping screen area, that is, the actual transmission is 3840 (column)*2160 (row) pixels (complete No. one screen). Similarly, what the right partition actually transmits is also the complete first picture.

It should be noted that the partition transmission shown in FIG. 3 refers to dividing the first picture along the vertical direction, but the partition transmission may refer to dividing the first picture along the horizontal direction, which is not specifically limited in this embodiment of the present application.

S220. According to the second frame, the first timing control chip controls the first driver chip set to drive pixels corresponding to the second frame in the pixel array to display.

S230. According to the third frame, the second timing control chip controls the second driving chipset to drive pixels corresponding to the third frame in the pixel array to display.

Specifically, after the image processing chip performs divisional transmission and image overlapping processing on the first picture, it generates the second picture and the third picture, and transmits the second picture and the third picture to the first timing control chip and the second picture respectively. The timing control chip, the first timing control chip controls the first driving chipset to drive the pixels corresponding to the second picture in the pixel array of the display panel to display according to the second picture; the second timing control chip controls the pixel corresponding to the second picture according to the third picture, Controlling the second driving chipset to drive the pixels corresponding to the third picture in the pixel array of the display panel to display.

It should be understood that after the first driver chipset and the second driver chipset respectively drive the pixels corresponding to the second picture and the third picture, the second picture and the third picture will be respectively displayed on the display panel, so as to finally complete the control of the second picture and the third picture. One screen display.

Through the screen display method, the embodiment of the present application can divide the first screen into the first sub-screen and the second sub-screen, and perform image overlapping on the first sub-screen and the second sub-screen respectively to obtain the corresponding second sub-screen. screen and the third screen, there is a partial screen overlapping area between the second screen and the third screen, the second screen corresponds to the first timing control chip, the third screen corresponds to the second timing control chip, and each timing control chip corresponds to a Drive chipset, so that each pixel in the overlapping area of the second picture and the third picture will be bidirectionally driven, in other words, each pixel in the overlapping area will be bidirectionally charged, so that the pixels in the overlapping area can be guaranteed The charging rate of each pixel is equalized to minimize the color deviation between pixels. In this way, the embodiment of the present application can meet the user's dual requirements for high touch precision and large size of the display device.

The charging time of the remote pixels is not enough, which reduces the touch accuracy of the display device, so as to meet the dual requirements of users for a display device with high touch accuracy and large size.

As a possible implementation manner, the first timing control chip inserts at least one blanking line into the second frame along the second direction, and the second timing control chip inserts at least one blanking line into the third frame along the second direction.

It should be understood that the first timing control chip and the second timing control chip respectively insert at least one blanking line into the second picture and the third picture along the second direction, and at least one blanking line is not used for picture display.

Specifically, when the first timing control chip inserts at least one blanking line into the second picture along the second direction, at least one blanking line can be distributed among multiple data lines corresponding to the second picture in a staggered manner, for example, One data line followed by one blanking line; alternatively, at least two data lines followed by one blanking line; alternatively, one data line followed by at least two blanking lines; or, at least two data lines followed by at least two blanking lines , etc., the embodiment of the present application does not specifically limit the specific distribution form of the blanking lines of at least one line in the second picture. The process of the second timing control chip inserting at least one blanking line into the third picture along the second direction is as described above.

It should be understood that each data row in the plurality of data rows may be used for screen display, or may be used for other purposes, for example, control information. Therefore, the data line can be a display data line, a control data line, or other types of data lines, but the blanking line is not used for screen display, which means that the blanking line is not a display data line.

Specifically, each blanking line in at least one blanking line is used for non-picture display, which can be understood as: when the display device receives picture data, it inserts a blanking line after each line of data received. Hidden line, the blank line is not used for actual display screen. During the time period corresponding to each blanking line, the display device is not used for displaying images, but for other purposes, such as playing audio or detecting touch.

By inserting at least one blanking line into the second picture and the third picture respectively by the first timing control chip and the second timing control chip, the total number of lines respectively corresponding to the second picture and the third picture can be increased, for example, the second The screen corresponds to 100 rows*100 columns. After the first timing control chip inserts 100 blanking rows into it, the second screen will correspond to 200 rows*100 columns. Realize other purposes in the corresponding time period, such as audio playback, etc.

As a possible implementation, the display device also includes a touch detection chip, and the method for displaying a picture further includes:

By using the touch detection chip to detect whether the pixels of the second picture and the third picture are touched from the pixel level within the time period corresponding to at least one blanking line, the embodiment of the present application can further improve the touch control of the display device. control accuracy.

As a possible implementation, the first picture may also be a partial picture of the complete picture, that is, the first picture acquired by the image processing chip is a part of the complete picture to be displayed by the display panel, not the whole picture.

As a possible implementation manner, the first direction is perpendicular to the second direction; or, the first direction is the same as the second direction, where the first direction is a vertical direction or a horizontal direction.

As a possible implementation manner, the pixel driven by each first driver chip in the first driver chip set is the same as the pixel driven by each corresponding second driver chip in the second driver chip set.

When the image processing chip divides the first picture to obtain multiple sub-pictures, the number of timing control chips is consistent with the number of sub-pictures, and the number of driving chipsets It is also consistent with the number of timing control chips.

More specifically, when the image processing chip performs partition transmission and image overlapping on the first picture to obtain N pictures, each picture in the N pictures corresponds to a timing control chip, and each timing control chip corresponds to a timing control chip. set of driving chips, N is a positive integer greater than 2, that is, how many pictures there are, and there are a corresponding number of timing control chips and driving chipsets.

For related descriptions of the first screen, the second screen, and the third screen, reference may be made to the foregoing content, and details are not repeated here.

Specifically, the image processing chip has the functions of partition transmission and image overlapping. After the first picture is divided into two sub-pictures, the first sub-picture and the second sub-picture are obtained, and the first sub-picture and the second sub-picture are respectively The images are overlapped to generate the second image and the third image, and then the image processing chip transmits them to the first timing control chip and the second timing control chip, and the corresponding first driving chip group and the second driving chip group to drive the corresponding pixels, so as to display the second frame and the third frame on the display panel.

As a possible implementation, the display device further includes: a touch detection chip, configured to detect whether the pixels in the pixel array respectively corresponding to the second picture and the third picture are within a time period corresponding to at least one blanking line being touched.

As a possible implementation manner, the display device further includes: a data transmission chip, configured to be responsible for data transmission between the image processing chip and the first timing control chip and the second timing control chip.

It should be understood that the image processing chip, timing control chip, and driver chip in the display device shown in FIG. 5 are described as upper-level descriptions, which may correspond to other devices or devices used to implement the screen display method shown in FIG. 2 . devices or chips.

As an exemplary description, the image processing chip is a system on chip (system on chip, SOC) chip, and the timing control chip is a timing control circuit (time controller, TCON) chip, wherein the number of TCON chips is the same as that of the first picture. The number of sub-pictures obtained by dividing in the first direction is related.

Specifically, the SOC chip is used to receive and process the first picture that needs to be displayed on the screen. The processing method is: divide the first picture into two sub-pictures, and perform image overlapping on the first sub-picture and the second sub-picture function, and then obtain the second picture and the third picture, and there is a partial overlapping area between the second picture and the third picture. In other words, the SOC chip supports the partition transfer function and the image overlapping function.

After the SOC chip obtains the second picture and the third picture after completing the partition transmission and image overlapping functions of the first picture, it transmits the second picture and the third picture to the corresponding two TCON chips respectively. There is a primary and secondary distinction between the two TCON chips, that is, there is a TCON master chip, and the remaining TCON chip is a TCON slave chip, and the TCON master and slave chips can communicate with each other, and the TCON master chip generates a synchronization signal , so as to realize synchronous driving of the pixels corresponding to the first picture by the two TCON chips.
