Detailed ways

In order to make the objectives, technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

An embodiment of the present invention provides a method for displaying an image, where the execution subject of the method is a terminal. The terminal may be any terminal with the function of displaying images, such as a mobile phone, a computer, etc., and the image may be any image that can be displayed on the terminal, such as photos, video images, and application images. The terminal can be provided with a processor, a memory, and a screen. The processor can be used to process the process of displaying images. The memory can be used to store the data required in the following processing and the data generated. The screen can be used to display the following: The content that needs to be displayed to the user during the processing, such as a target image, may include a display panel on the screen. The display panel includes a plurality of display units corresponding to pixels, and each display unit includes a sub-display unit corresponding to a white channel and a plurality of primary color channels respectively. The corresponding sub-display unit is shown in Figure 1. The terminal may also be provided with a screen, an input unit, and a communication component, and the input unit may be used by the user to input instructions or setting information to the terminal. In this embodiment, the terminal is used as a mobile phone, and the multiple primary color channels are red, green, and blue color channels for detailed description of the scheme. Other situations are similar, and are not repeated in this embodiment.

The processing flow shown in FIG. 2 will be described in detail below in conjunction with the specific embodiments, and the content may be as follows:

Step 201, acquiring the image type of the image to be displayed.

The image type can be type information that can reflect the color composition of the image, and can be divided into black and white images, grayscale images, and color images.

In the implementation, the terminal is in a standby state, the backlight of the screen is turned off, and there is no display content on the screen. The user can perform operations on the terminal to control the terminal to display the image browsed by the user (ie, the image to be displayed). Before the image, the terminal can receive a display instruction of the image to be displayed, so as to obtain the image type of the image to be displayed. Here, the image type of the image to be displayed can be determined by the image data of the image to be displayed, the image data can include pixel values corresponding to all pixels of the image to be displayed, and the pixel value corresponding to each pixel can be determined by multiple primary color channels. channel value composition. Specifically, the image data of the image to be displayed can be obtained first, and then the image type of the image to be displayed can be determined by comparing the channel values of each primary color channel in the image data. If the channel value of each primary color channel in any pixel of the image to be displayed is are the same, and both are 255 or 0, the image to be displayed can be considered to be a black and white image; if the channel values of each primary color channel in any pixel of the image to be displayed are the same, the image to be displayed can be considered to be a grayscale image; If the channel values of the primary color channels of each pixel of the displayed image are chaotic and irregular, the image to be displayed can be considered as a color image.

Step 202 , if the image to be displayed is a grayscale image, it is determined that the image to be displayed is only image data in the white channel.

In the implementation, since the image data of the existing image is generally fixed image data of three primary colors of red, green and blue, that is, the image data of each pixel only contains the channel values of the three primary color channels of the red channel, the green channel and the blue channel. , when the channel values of the red, green and blue primary color channels are the same, a grayscale pixel can be formed. In this way, if it is detected that the channel values of each primary color channel of any pixel in the image to be displayed are the same, the image to be displayed can be considered to be a grayscale image. At this time, considering that the terminal involved in this solution contains multiple primary color channels and white channels at the same time, when a grayscale image needs to be displayed, the sub-display unit corresponding to the white channel can be enabled, and it is determined that the image to be displayed is only under the white channel The image data is to convert the channel values of the red, green and blue primary color channels to the channel values of the white channel.

Optionally, before displaying the image to be displayed, the terminal may perform the determination processing of the above image data at different times. Correspondingly, step 202 may have the following multiple processing methods:

Manner 1, if the image to be displayed is a grayscale image, when generating the image to be displayed, the CPU or GPU determines that the image to be displayed is only image data in the white channel.

In implementation, when the terminal displays the image to be displayed, the CPU (Central Processing Unit, Central Processing Unit) or GPU (Graphics Processing Unit, Graphics Processing Unit) may first generate the corresponding image according to the running data of the application to which the image to be displayed belongs. Then the application processor of the terminal can transmit the image data of the image to be displayed to the display panel of the terminal, and then the data circuit of the display panel of the terminal can convert the received image data into a voltage signal, and convert the received image data into a voltage signal. The voltage signal is supplied to the display unit of each pixel, so that the display panel displays the to-be-displayed image. Based on the above process, before the terminal generates the image to be displayed, if the running data of the application determines that the image to be displayed is a grayscale image, it can directly use the CPU or GPU to determine that the image to be displayed is only in white when generating the image to be displayed. The image data under the channel is not selected to generate the image data under the red, green and blue color channels. In this way, it can be understood that the data volume of the image data in the white channel can be reduced to one third compared to the red, green and blue color channels, and further, in the subsequent image data storage, transmission, and rendering, only one-third Therefore, the corresponding processing resources can be saved, and the power consumption when displaying the image to be displayed can be reduced.

Method 2: If the image to be displayed is a grayscale image, before the application processor transmits the primary color image data of the image to be displayed to the display panel, the transmission controller determines that the image to be displayed is only the image data of the white channel.

The primary color image data may be image data containing only primary color channels. For example, each pixel in most images is composed of red, green, and blue primary color channels, and the primary color image data may be channel values of red, green, and blue primary color channels.

In implementation, when the terminal displays the image to be displayed, the CPU or GPU can first generate the corresponding primary color image data of the image to be displayed according to the running data of the application to which the image to be displayed belongs, and then the application processor of the terminal can The primary color image data is transmitted to the display panel of the terminal, and then the data circuit of the terminal display panel can convert the received primary color image data into a voltage signal, and provide the voltage signal to the display unit of each pixel, so that the display panel can process the image to be displayed. show. Based on the above process, after generating the image to be displayed, if the terminal determines that the image to be displayed is a grayscale image, before the application processor transmits the primary color image data to the display panel, the transmission controller can determine that the image to be displayed is only a grayscale image. The image data in the white channel, that is, the image data in the red, green, and blue color channels are converted into image data only in the white channel before the primary color image data is transmitted to the display panel. In this way, it can be understood that the data volume of the image data in the white channel can be reduced to one third compared to the red, green and blue color channels, and further, during subsequent image data transmission and rendering, only one third of the image data needs to be processed. Therefore, the corresponding processing resources can be saved, and the power consumption when displaying the image to be displayed can be reduced.

Mode 3: If the image to be displayed is a grayscale image, after the data circuit of the display panel acquires the primary color image data of the image to be displayed, the data circuit determines the image data of the image to be displayed only in the white channel.

In implementation, when the terminal displays the image to be displayed, the CPU or GPU can first generate the corresponding primary color image data of the image to be displayed according to the running data of the application to which the image to be displayed belongs, and then the application processor of the terminal can The primary color image data is transmitted to the display panel of the terminal, and then the data circuit of the terminal display panel can convert the received primary color image data into a voltage signal, and provide the voltage signal to the display unit of each pixel, so that the display panel can process the image to be displayed. show. Based on the above process, after the terminal generates the to-be-displayed image and the display panel obtains the primary color image data of the to-be-displayed image transmitted by the application processor, if the to-be-displayed image is a grayscale image, before rendering the to-be-displayed image, the The data circuit of the display panel determines the image data of the image to be displayed only in the white channel, that is, converts the image data in the red, green and blue color channels into the image data only in the white channel. In this way, it can be understood that the data volume of the image data in the white channel can be reduced to one third compared to the red, green and blue color channels, and further, when the subsequent image data is rendered, only one third of the data volume needs to be Therefore, the corresponding processing resources can be saved, and the power consumption when displaying the image to be displayed can be reduced. Further, if a memory is configured in the display panel for storing the image data of the image to be displayed transmitted by the application processor, when the image to be displayed is a grayscale image, only a small amount of storage space can be occupied. Furthermore, if the terminal is dedicated to displaying grayscale images, the display panel can use a smaller memory, which saves the production cost of the display panel, and at the same time, the area of the display panel IC can be appropriately reduced. The related functions of smart panel can be realized.

Step 203: Display and output the determined image data based on the sub-display unit corresponding to the white channel in the display panel.

In implementation, after converting the image data of the image to be displayed, the terminal can enable the sub-display unit corresponding to the white channel, and convert the determined image data into a voltage signal, so as to provide the voltage signal to the above-mentioned white channel through the data circuit The corresponding sub-display unit, and then the terminal can display and output the determined image data based on the sub-display unit corresponding to the white channel in the display panel. In this way, since the light transmittance of the filter of the sub-display unit corresponding to the white channel is relatively strong, when a grayscale image with a certain brightness needs to be displayed, the sub-display unit corresponding to the white channel has a lower demand for the backlight intensity, thus saving energy. The power consumed by the backlight when displaying grayscale images.

It can be understood that the above three methods for determining the image data of the image to be displayed near the white channel occur at different moments in the process of displaying the image. It is not difficult to see that the sooner the image data in the white channel is determined, the more power consumption is saved, that is, when conditions permit, the image display process can be preferably performed in the first mode.

In this embodiment of the present invention, when displaying an image, if the image to be displayed is a grayscale image, the terminal can determine that the image to be displayed is only the image data in the white channel, and then can enable the sub-display unit corresponding to the white channel to perform the image processing on the to-be-displayed image. show. In this way, because the white filter in the sub-display unit corresponding to the white channel has a strong light transmittance, when a certain screen brightness is required, the light intensity of the backlight is required to be low, so that the backlight consumes less power when displaying the interface. . At the same time, compared with the red, green and blue color channels, only the white channel is used to display grayscale images, which can effectively reduce the amount of data that needs to be processed in the display process, thereby saving the power consumed by the terminal for processing image data.

Another embodiment of the present invention also discloses a display panel, which is used to implement the above method for displaying images, and the content may be as follows:

The display panel includes a display unit with a plurality of pixels, and each display unit includes a sub-display unit corresponding to a white channel and a sub-display unit corresponding to a plurality of primary color channels, wherein, as shown in FIG. 3 , the sub-display units corresponding to the plurality of primary color channels The display areas are equal, and the display area of the sub-display unit corresponding to the white channel is larger than the display area of the sub-display unit corresponding to each primary color channel.

Optionally, the plurality of primary color channels include a red channel, a blue channel and a green channel.

In this way, pixels of different colors can be formed based on the three primary color channels of red, green, and blue.

Optionally, the display area of the sub-display unit corresponding to the white channel is less than half of the display area of the display unit.

In this way, the white channel can be prevented from having too much influence on the accuracy of the pixel color.

Optionally, the display area of the sub-display unit corresponding to the white channel accounts for 1/3 of the display area of the display unit.

Optionally, each sub-display unit includes a TFT (Thin Film Transistor).

Optionally, as shown in FIG. 4 , the display panel includes a gate circuit and a data circuit, the gate electrode of each TFT is connected to the gate circuit, and the source electrode is connected to the data circuit.

In this way, the conduction or not of the TFTs in the sub-display units corresponding to the white channel and each primary color channel can be controlled by a unified gate circuit.

Optionally, as shown in FIG. 5 , the display panel includes a first gate circuit, a second gate circuit and a data circuit, the source of each TFT switch is connected to the data circuit, and the TFT switch of the sub-display unit corresponding to each primary color channel The gate of the TFT switch is connected to the first gate circuit, and the gate of the TFT switch of the sub-display unit corresponding to each white channel is connected to the second gate circuit.

In this way, the first gate circuit and the second gate circuit can respectively control whether the TFTs in the sub-display units corresponding to the white channel and each primary color channel are turned on or off.
