Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
The embodiment of the invention provides a method for displaying an image, wherein an execution main body of the method is a terminal. The terminal can be any terminal with a function of displaying images, such as a mobile phone, a computer, and the like, and the images can be any images capable of being 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, wherein the processor may be configured to process a process of displaying an image, the memory may be configured to store data required in the following process and generated data, the screen may be configured to display content, such as a target image, required to be displayed to a user in the following process, and 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 a white channel and a sub-display unit corresponding to a plurality of primary color channels, as shown in fig. 1. The terminal can also be provided with a screen, an input unit and a communication component, wherein the input unit can be used for inputting instructions or setting information to the terminal by a user. In this embodiment, the terminal is used as a mobile phone, and the plurality of primary color channels are red, green, and blue channels to perform detailed description of the scheme.
The process flow shown in fig. 2 will be described in detail below with reference to the specific embodiments, and the contents may be as follows:
The image type may be type information capable of representing color composition of the image, and may be divided into a black-and-white image, a gray-scale image, and a color image.
In implementation, when the terminal is in a standby state, the backlight of the screen of the terminal is turned off, no display content exists on the screen, the user can operate on the terminal to control the terminal to display an image browsed by the user (i.e., an image to be displayed), and before the image to be displayed is displayed, the terminal can receive a display instruction of the image to be displayed, so that the image type of the image to be displayed can be acquired. Here, the image type of the image to be displayed may be determined by image data of the image to be displayed, the image data may include pixel values corresponding to all pixels of the image to be displayed, and the pixel value corresponding to each pixel may be composed of channel values of a plurality of primary color channels. Specifically, image data of an image to be displayed may be obtained first, and then the image type of the image to be displayed is determined by comparing channel values of each primary color channel in the image data, and if the channel values of each primary color channel in any one pixel of the image to be displayed are the same and are 255 or 0, the image to be displayed may be considered as a black-and-white image; if the channel values of the primary color channels in any pixel of the image to be displayed are the same, the image to be displayed can be regarded as a gray image; if the channel values of the primary color channels of each pixel of the image to be displayed are disordered, the image to be displayed can be regarded as a color image.
In the implementation, because the image data of the existing image is generally the image data of the fixed red, green and blue three primary colors, 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 three primary color channels are the same, the gray scale pixel can be formed. In this way, if it is detected that the channel values of the respective primary color channels of any one pixel in the image to be displayed are the same, the image to be displayed can be considered as a grayscale image. At this time, considering that the terminal related to the scheme includes a plurality of primary color channels and a white channel at the same time, when a gray image needs to be displayed, the sub-display unit corresponding to the white channel can be started, and image data of the image to be displayed only under the white channel is determined, that is, channel values of red, green and blue primary color channels are converted into channel values of the white channel.
Optionally, before displaying the image to be displayed, the terminal may perform the above-mentioned determination processing on the image data at different times, and accordingly, step 202 may have the following multiple processing manners:
in the first mode, if the image to be displayed is a gray image, when the image to be displayed is generated, the CPU or the GPU determines that the image data of the image to be displayed is only in the white channel.
In implementation, when the terminal displays an image to be displayed, a CPU (Central Processing Unit) or a GPU (Graphics Processing Unit) may generate image data of the corresponding image to be displayed according to operation data of an application to which the image to be displayed belongs, and then the application processor of the terminal may transmit the image data of the image to be displayed to a display panel of the terminal, and then a data circuit of the display panel of the terminal may convert the received image data into a voltage signal and provide the voltage signal to a display Unit of each pixel, so that the display panel displays the image to be displayed. Based on the process, before the terminal generates the image to be displayed, if the image to be displayed is judged to be a gray image by the application running data, the image data of the image to be displayed under a white channel is determined directly by a CPU or a GPU, and the image data under red, green and blue channels is not selected to be generated. Therefore, it can be understood that, compared with a red, green and blue three-color channel, the data volume of the image data under the white channel can be reduced to one third, and then, when the subsequent image data is stored, transmitted and rendered, only one third of the data volume needs to be processed, so that the corresponding processing resources can be saved, and the electric energy loss when the image to be displayed is reduced.
In the second mode, if the image to be displayed is a gray 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 in the white channel.
The primary image data may be image data including only primary color channels, for example, each pixel in most images is composed of three primary color channels of red, green and blue, and the primary image data may be channel values of three primary color channels of red, green and blue.
In implementation, when the terminal displays an image to be displayed, the CPU or the GPU may generate 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 may transmit the primary color image data to the display panel of the terminal, and then the data circuit of the display panel of the terminal may 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 displays the image to be displayed. Based on the above process, after the terminal generates the image to be displayed, if the image to be displayed is judged to be a gray image, before the application processor transmits the primary color image data to the display panel, the transmission controller determines the image data of the image to be displayed only under the white channel, that is, before the primary color image data is transmitted to the display panel, the image data under the red, green and blue channels is converted into the image data under the white channel. Therefore, it can be understood that, compared with a red, green and blue three-color channel, the data volume of the image data under the white channel can be reduced to one third, and then, when the subsequent image data is transmitted and rendered, only one third of the data volume needs to be processed, so that the corresponding processing resources can be saved, and the electric energy loss when the image to be displayed is reduced.
And if the image to be displayed is a gray image, after the data circuit of the display panel acquires the primary color image data of the image to be displayed, determining the image data of the image to be displayed under the white channel only through the data circuit.
In implementation, when the terminal displays an image to be displayed, the CPU or the GPU may generate 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 may transmit the primary color image data to the display panel of the terminal, and then the data circuit of the display panel of the terminal may 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 displays the image to be displayed. Based on the above process, after the terminal generates the image to be displayed and the display panel acquires the primary color image data of the image to be displayed transmitted by the application processor, if the image to be displayed is a gray image, the data circuit of the display panel can determine the image data of the image to be displayed only under the white channel before the image to be displayed is rendered, that is, the image data under the red, green and blue channels is converted into the image data under the white channel. Therefore, it can be understood that, compared with a red, green and blue three-color channel, the data volume of the image data under the white channel can be reduced to one third, and then, when the subsequent image data is rendered, only one third of the data volume needs to be processed, so that the corresponding processing resources can be saved, and the electric energy loss when the image to be displayed is 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, only a small amount of memory space may be occupied when the image to be displayed is a grayscale image. Moreover, if the terminal is specially used for displaying gray images, the display panel can adopt a smaller memory, so that the manufacturing cost of the display panel is saved, meanwhile, the area of the display panel IC can be properly reduced, and in addition, the related functions of the intelligent panel smart panel can be realized by using the smaller memory.
And step 203, displaying and outputting the determined image data based on the sub-display unit corresponding to the white channel in the display panel.
In implementation, after the image data of the image to be displayed is converted, the terminal may start the sub-display unit corresponding to the white channel, and convert the determined image data into the voltage signal, so that the voltage signal is provided to the sub-display unit corresponding to the white channel through the data circuit, and then the terminal may display and output the determined image data based on the sub-display unit corresponding to the white channel in the display panel. Therefore, as the light transmission capability of the optical filter of the sub-display unit corresponding to the white channel is stronger, when a gray image with certain brightness needs to be displayed, the requirement of the sub-display unit corresponding to the white channel on the backlight intensity is lower, and the electric energy consumed by the backlight when the gray image is displayed can be saved.
It can be understood that the above three ways of determining the image data of the image to be displayed near the white channel occur at different times in the process of displaying the image, and regarding the occurrence time, the first way precedes the second way precedes the third way, which is not difficult to see, the earlier the image data of the white channel is determined, the more power consumption is saved, that is, under the condition permission, the image display processing can be performed in the first preferred way.
In the embodiment of the invention, when the image is displayed, if the image to be displayed is a gray image, the terminal can determine that the image to be displayed is only image data under the white channel, and then the sub-display unit corresponding to the white channel can be started to display the image to be displayed. Therefore, the white filter in the sub-display unit corresponding to the white channel has stronger light transmission capability, so that when certain screen brightness is required, the light intensity requirement of backlight is lower, and the electric energy consumed by the backlight when an interface is displayed is less. Meanwhile, compared with a red, green and blue channel, the gray image is displayed by only adopting the white channel, so that the data volume needing to be processed in the display process can be effectively reduced, and the electric quantity consumed by the terminal for processing the image data can be saved.
Another embodiment of the present invention further discloses a display panel, which is used for implementing the method for displaying images, and the content can be as follows:
the display panel includes a plurality of display units of pixels, 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 display areas of the sub-display units corresponding to the plurality of primary color channels 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 includes a red color channel, a blue color channel, and a green color 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 color channels are rectangular display areas arranged in parallel and equal in length.
Optionally, the rectangular display areas of the sub-display units in each display unit are arranged in parallel in a manner that the long sides are vertical according to the same arrangement sequence.
Optionally, the rectangular display areas of the sub-display units in each display unit are arranged in parallel in a manner that the long sides are horizontal according to the same arrangement sequence.
Optionally, the display area of the sub-display unit corresponding to the white channel is smaller than half of the display area of the display unit.
In this way, it is possible to avoid that the white channel has too much influence on the accuracy of the pixel color.
Optionally, the display area of the sub-display unit corresponding to the white channel occupies 1/3 of the display area of the display unit.
Alternatively, each sub-display unit includes a TFT (Thin Film Transistor).
Alternatively, 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.
Thus, the uniform gate circuit can control the on/off of the TFT in the sub-display unit corresponding to the white color channel and each primary color channel.
Alternatively, 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, the gate of the TFT switch of the sub-display unit corresponding to each primary color channel is connected to the first gate circuit, and the gate of the TFT switch of the sub-display unit corresponding to each white color channel is connected to the second gate circuit.
Thus, the first gate circuit and the second gate circuit can respectively control the conduction or non-conduction of the TFTs in the sub-display units corresponding to the white color channel and each primary color channel.
