Detailed ways

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

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

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

Step 201, detecting the current ambient light intensity.

In implementation, when the terminal is displaying images, if the current ambient light is strong, the user cannot clearly see the images displayed on the terminal screen. Therefore, when the user operates the terminal, the terminal can detect the current ambient light intensity in real time, and perform subsequent processing based on the ambient light intensity. Of course, under normal circumstances, only when the ambient light is too strong will affect the user’s browsing of the displayed images when the user is outdoors during the day, so the terminal can also detect that the user is located outdoors and the current time is in the daytime. Start to detect the current ambient light intensity in real time. Alternatively, the above function may also be enabled by the user himself. Here, the terminal may perform detection through a photosensitive element, and the photosensitive element may be an ambient light sensor or the like.

Step 202, if the ambient light intensity is greater than the preset intensity threshold, determine the image data corresponding to the image data of the image to be displayed under each color channel.

In implementation, an intensity threshold (that is, a preset intensity threshold) can be preset for the ambient light intensity. When the ambient light intensity is greater than the preset intensity threshold, even if the backlight intensity of the terminal screen is adjusted to the maximum, it will be difficult for the user to see clearly. What is displayed on the terminal screen. It should be noted that this solution can be implemented specifically by a terminal system program, or can be implemented by a third-party application installed on the terminal. Correspondingly, the aforementioned preset intensity threshold can be set by the developer of the terminal, or can be It is set by the developer of the third-party application. In addition, users can also adjust the above-mentioned preset intensity thresholds according to their own needs. For example, if the user finds that the current ambient light has affected the viewing of the image to be displayed during the use of the terminal, the user can control the terminal to set the preset intensity threshold. The intensity threshold changes to the current ambient light intensity.

It can be understood that the display panel included in the terminal includes a plurality of display units corresponding to the pixels, and each display unit includes sub-display units corresponding to the white channel and sub-display units corresponding to the red, green and blue channels respectively. Each sub-display unit is equipped with a color filter of a corresponding color, and each color filter has a different color, and its light transmittance is correspondingly different, which can be represented by light transmittance. Here, based on a large number of tests, the transmittance of the color filters in different sub-display units (also referred to as the transmittance of the sub-display units) can be roughly estimated, specifically as follows: the transmittance of the red filter R The light rate is about 15%, the light transmittance of the green filter G is about 50%, the light transmittance of the blue filter B is about 10%, and the light transmittance of the white filter W is about 95%. It should be noted that the above-mentioned light transmittances are examples and are not intended to limit this solution. In this way, the light transmittance of a display unit can be determined based on the light transmittance of the sub-display unit corresponding to each color channel and the display area of the sub-display unit corresponding to each color channel. Specifically, assuming that the white channel corresponds to The display area of the sub-display unit accounts for 1/3 of the display area of a display unit, and the light transmittance of a display unit can be: 2/3*1/3*(15%+50%+10%)+1/3 *95%=0.16+0.32=0.48=48%. Considering that each display unit of a traditional display panel only includes sub-display units corresponding to red, green and blue color channels, the light transmittance of a display unit in a traditional display panel can be: 1/3*(15%+ 50%+10%)=25%. Therefore, relatively speaking, the light transmittance of the display panel adopted in the present application is 1.92 times (48/25=1.92) of the light transmittance of the traditional display panel, that is, the light transmittance has increased by 92%. The brightness of the terminal screen is increased by 92%. In this way, if you want the terminal screen to achieve the same brightness, compared with the traditional display panel, the display panel in this application can lower the backlight intensity of the display panel according to the above results. Specifically, the backlight intensity can be reduced to 52% of the original (25/48=0.52). Of course, considering that the wiring and BM area of the sub-display unit corresponding to the white channel are increased, the light transmittance of the display panel in this application may drop a little, which can be assumed to be 80%.

Therefore, after the terminal detects the current ambient light intensity, it can compare the ambient light intensity with the above-mentioned preset intensity threshold, and if the ambient light intensity is greater than the preset intensity threshold, it can activate the sub-display unit corresponding to the white channel. Achieve the effect of increasing the screen brightness, so that the user can clearly see the content displayed on the terminal screen. In this way, before displaying the image to be displayed, the terminal can receive a display instruction of the image to be displayed, and obtain the image data of the image to be displayed, and the image data can include pixel values corresponding to all pixels of the image to be displayed, and each pixel corresponds to A pixel value of can be composed of channel values of multiple primary color channels. Further, since the image data of the existing image is generally the image data of fixed red, green and blue primary colors (R, G, B), that is, the image data of each pixel only includes the three channels of red channel, green channel and blue channel. At this time, the terminal has enabled multiple primary color channels and white channels at the same time. Therefore, the terminal needs to convert the image data of the image to be displayed, that is, to determine the image data corresponding to the image to be displayed in each color channel image data below.

Optionally, step 202 may have multiple processing methods as follows:

Method 1, if the ambient light intensity is greater than the preset intensity threshold, determine the brightness value of each pixel according to the channel values of multiple primary color channels of each pixel in the image to be displayed; keep the multiple primary color channels of each pixel in the image to be displayed The channel value of the primary color channel is unchanged, and the brightness value of each pixel is determined as the channel value of the white channel of each pixel.

In implementation, when it detects that the current ambient light intensity is greater than the preset intensity threshold, the terminal can realize the screen highlight mode by activating the sub-display unit corresponding to the white channel, that is, first acquire multiple The channel values R, G, and B of the primary color channels, and then determine the brightness value of each pixel according to the channel values of the multiple primary color channels. Specifically, it can be determined by the conversion formula of image data in RGB color space and YCbCr color space , where the brightness value Y=0.299R+0.587G+0.114B. After that, the channel values of multiple primary color channels of each pixel in the image to be displayed may be kept unchanged, and then the channel value of the white channel of each pixel may be determined as the brightness value calculated above. For example, the brightness values of the original two pixels are Y1=100 and Y2=50 respectively, then the channel values of the white channel of these two pixels are 100 and 50, so the Y ratio of the two pixels will be maintained, which can be Readability is effectively guaranteed.

Method 2, if the ambient light intensity is greater than the preset intensity threshold, determine the brightness value of each pixel according to the channel values of multiple primary color channels of each pixel in the image to be displayed; expand the brightness value of each pixel proportionally; The channel values of multiple primary color channels of each pixel are determined according to the expanded brightness value, and the expanded brightness value is determined as the channel value of the white channel of each pixel.

In implementation, when it detects that the current ambient light intensity is greater than the preset intensity threshold, the terminal can realize the screen highlight mode by activating the sub-display unit corresponding to the white channel, that is, first acquire multiple The channel values R, G, and B of the primary color channels, and then determine the brightness value of each pixel according to the channel values of the multiple primary color channels. Specifically, it can be determined by the conversion formula of image data in RGB color space and YCbCr color space , where the brightness value Y=0.299R+0.587G+0.114B. Afterwards, the brightness value of each pixel can be enlarged proportionally. For example, if three pixels are selected and their brightness values are 20, 40, and 50 respectively, and the brightness values of the three pixels are proportionally enlarged by 1.5 times, the enlarged The brightness values of the pixels are 30, 60, and 75 respectively. In this way, if the brightness values of the pixels of the image to be displayed are distributed between 20 and 170, the brightness values can be evenly transformed into 20 to 255 after expansion, so as to improve the overall brightness. Effect. Furthermore, the channel values of multiple primary color channels of each pixel can be determined according to the expanded brightness value, specifically, it can be determined through the conversion formula of image data in RGB color space and YCbCr color space, wherein, the blue density offset Cb = 0.564(B-Y), red density offset Cr = 0.713(R-Y), in order to ensure that the color deviation of the image to be displayed is not large, the above values of Cb and Cr can be kept unchanged, and then re-set according to the enlarged brightness value The channel values of multiple primary color channels of each pixel are determined, and the channel value of the white channel of each pixel is determined as the above-mentioned expanded brightness value.

Optionally, in the color precision mode, the terminal will not enable the sub-display unit corresponding to the white channel in each pixel. Correspondingly, the processing in step 202 can be as follows: if the ambient light intensity is greater than the preset intensity threshold, and the current display If the mode is not color-accurate mode, then determine the image data corresponding to the image data of the image to be displayed under each color channel.

In implementation, the display panel of the terminal includes display units corresponding to multiple pixels, and each display unit includes sub-display units corresponding to the white channel and sub-display units corresponding to multiple primary color channels. When displaying images, the terminal supports using all Color channels and use part of the color channels to display, that is, the terminal supports multiple display modes. Specifically, the various display modes can be divided into black and white mode, standard mode and color precision mode, wherein, in the black and white mode, the terminal can only enable the sub-display unit corresponding to the white channel, that is, corresponding to the white channel; in the standard mode, the terminal The sub-display unit corresponding to the white channel and the sub-display units corresponding to multiple primary color channels can be enabled at the same time, that is, corresponding to the white channel and multiple primary color channels; in the color precision mode, the terminal can only enable the sub-display units corresponding to multiple primary color channels , corresponding to multiple primary color channels. It is not difficult to understand that only the white channel is enabled in the black and white mode, so there will be no color in the image. The standard mode enables the white channel and multiple primary color channels at the same time. The image is a color image, but due to the interference of the white channel, the color formed by multiple primary color channels The color of the pixel will deviate from the primary color. The color precision mode only enables the primary color channel, which removes the interference of the white channel and makes the color more accurate. In this embodiment, the purpose of increasing screen brightness is achieved by enabling the white channel. Therefore, if the detected ambient light intensity is greater than the preset intensity threshold, and the current display mode is not a color-accurate mode (such as black and white mode or standard mode), Only then does the subsequent process of determining the image data corresponding to the image data of the image to be displayed under each color channel, if the current display mode is the color precision mode, keep the image data of the image to be displayed unchanged.

Step 203, based on the sub-display units corresponding to each color channel in the display panel, display and output the determined image data.

In implementation, after the terminal converts the image data of the target image, it can activate the sub-display unit corresponding to each color channel in the display panel, and convert the determined image data into a voltage signal, so that the voltage signal can be converted into Each sub-display unit corresponding to the color channel is provided, so that the terminal can display and output the determined image data based on the sub-display unit corresponding to each color channel in the display panel.

In the embodiment of the present invention, when displaying an image, the terminal can first detect the current ambient light intensity, and when the ambient light intensity is greater than the preset intensity threshold, the white channel in the display panel can be enabled, and the image data of the image to be displayed can be converted , determine the image data under each color channel, and then display and output the determined image data based on the sub-display units corresponding to each color channel in the display panel. In this way, since the sub-display unit corresponding to the white channel with higher light transmittance is added in the display unit, when the ambient light intensity is high, the brightness of the displayed image can be enhanced by enabling the white channel and converting the image data, There is no need to greatly increase the intensity of the backlight, so that the backlight consumes less power when displaying images.

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

The display panel includes a plurality of pixel display units, and each display unit includes a sub-display unit corresponding to a white channel and a plurality of sub-display units corresponding to a plurality of primary color channels, wherein, as shown in FIG. 3 , the sub-display units corresponding to a 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 multiple 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 areas of the sub-display units corresponding to the multiple primary color channels and the sub-display units corresponding to the white channel are rectangular display areas of equal length arranged side by side.

Optionally, the rectangular display areas of the sub-display units in each display unit are arranged side by side in the same sequence with the long sides vertical.

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 avoid 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 Field Effect Transistor, Thin Film Transistor).

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

In this way, a unified gate circuit can control whether the TFTs in the sub-display units corresponding to the white channel and each primary color channel are turned on or not.

Optionally, as shown in Figure 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 each white channel 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, whether the TFTs in the sub-display units corresponding to the white channel and each primary color channel are turned on or not can be controlled by the first gate circuit and the second gate circuit respectively.
