Referring to fig. 1, a schematic diagram of a hardware structure of an alternative example of an electronic device suitable for implementing the pixel compensation method and apparatus proposed in the present application is shown, where the electronic device may include, but is not limited to: terminal that has the display screen such as smart mobile phone, panel computer, wearable equipment, personal Computer (PC), netbook, intelligent wrist-watch and desktop computer, this application does not do the restriction to this electronic equipment's product type.
As shown in fig. 1, the electronic device may include a main board 11, a display panel 12, a memory 13, and a processor 14, wherein:
the main board 11 may be called a main board (main board) or a system board (system board), and is installed in a main chassis of a computer, and is one of the most basic and important components of the computer. The main circuit System of the computer, such as a BIOS (Basic Input/Output System) chip, an I/O control chip, a keyboard and panel control switch interface, an indicator light connector, an expansion slot, a motherboard, and a dc power supply connector of the plug-in card, may be mounted on the rectangular circuit board. Therefore, the main board is a core of a computer hardware system, and the structure, shape and the like of the main board in the electronic device are not limited by the application and can be determined according to the actual functional requirements of the electronic device.
Display panel 12 can be connected with mainboard 11, and in this application, this display panel 12 can contain a plurality of sub display areas, and can dispose a grey sub pixel to at least one word display area to the value range of the colour value of this sub display area, confirm the colour gradation quantity of this grey sub pixel.
In this embodiment of the present application, a sub-display area may refer to a display area of a pixel, and in general, a pixel may be composed of three color sub-pixels, such as R (red), G (green), and B (blue) sub-pixels, and electrical performance parameters of the sub-pixels may be adjusted to realize adjustment of the whole pixel level, that is, to change a color value of the pixel.
In view of the above, in combination with the above description of the technical concept of the present application, it is proposed that, without changing the arrangement relationship between the original sub-display regions in the display panel and the size of each sub-display region, a gray sub-pixel is configured by using the gap between the adjacent sub-display regions, and by adjusting the gray sub-pixel, positive and negative compensation and adjustment of a color sub-pixel or an original pixel (such as an RGB pixel, that is, a sub-display region) are achieved, so as to achieve adjustment of attribute parameters such as luminance, color temperature, color gamut, saturation, and the like of the sub-display regions, thereby changing the display state of the display regions.
It should be noted that, regarding the configuration corresponding relationship between the grayscale sub-pixel and each sub-display region, the present application is not limited, and in order to improve the control accuracy, one grayscale sub-pixel may be configured in one sub-display region; if the control accuracy is allowed to be properly reduced, a gray sub-pixel may be configured in a display area formed by two or more sub-display areas, that is, a plurality of sub-display areas are separated, and a gray sub-pixel may be configured in a sub-display area, but the number of the separated sub-display areas may be the same or different, and may specifically be determined according to the display control requirement of the electronic device.
It can be understood that, in the electronic device used by the user, since the display panel is determined and the configuration correspondence relationship cannot be adjusted, according to the pixel compensation implementation method provided by the present application, the adjustment effect of the display state that can be achieved is often determined. Moreover, for the configuration correspondence relationship of different contents, the number of sub-pixels included in each of the sub-display regions in the determined display panel may be the same (e.g., four sub-pixels of R, G, B, and gray), or may be different (e.g., one sub-display region includes four sub-pixels of R, G, B, and gray, and another sub-display region includes three sub-pixels of R, G, and B).
For example, referring to fig. 2a, a schematic diagram of an arrangement relationship of color sub-pixels of a display panel, and fig. 2b, which is applied to a pixel compensation implementation method provided in the present application, a schematic diagram of an arrangement relationship of sub-pixels of a display panel is shown. If it is desired to achieve high-precision display control, a single gray-scale sub-pixel (such as the grid marked with gray in fig. 2b, but not limited to the display panel pixel layout shown in fig. 2 a) may be disposed in the gap between two adjacent sub-display regions, and the size and shape of the divided region of the gray-scale sub-pixel is the same as that of each color sub-pixel included in the sub-display region. However, the present invention is not limited to this arrangement, and the implementation manner of adding the grayscale sub-pixels to the color sub-pixels having other arrangements is similar, and the detailed description thereof is omitted here.
In combination with the above description of the technical concept of the present application, the present application is to implement adaptive sub-pixel compensation adjustment based on the brightness difference of the external ambient light to the different illuminated areas of the display panel of the electronic device, that is, the gray sub-pixels of the compensation adjustment area configured in the sub-display area of the display panel are used in cooperation with the backlight intensity, etc. to implement adaptive adjustment, so that the eyes of a user feel more comfortable objectively and the display content of the screen is clearer.
Therefore, in order to realize accurate compensation adjustment, the application proposes to grade the color levels of the gray sub-pixels according to the value range of the color values of the sub-display areas, such as the value range of the color values of 0 to 255 of the RGB sub-pixels, so as to obtain the color levels of the gray sub-pixels with a plurality of continuous values, so that different color values all have corresponding color level values of the gray sub-pixels.
In a possible implementation manner, taking the color values of 0 to 255 of the RGB sub-pixels as an example, the grayscale sub-pixels can be divided into 256 levels, which are denoted as 1 level, 2 level, 3 level \8230, m level \8230, 255 level, 256 level, etc., and the marking manner of the 256 consecutive color levels of the grayscale sub-pixels according to the present application is not limited to this continuous digital coding marking manner, and may be determined as appropriate.
In another possible implementation manner, as described in the foregoing analysis, in the step of classifying the color levels of the gray sub-pixel, a number of consecutive color values may also correspond to one color level of the gray sub-pixel, so that the number of color levels of the gray sub-pixel is less than 256, and the specific number may be determined according to the classification result, which is not listed here in this embodiment of the present application.
It should be noted that the composition structure of the display panel 12 is not limited to the above description, and may further include components such as a backlight plate and a backlight source according to the display category, which are not listed herein.
The memory 13 may be used to store a program for implementing the pixel compensation implementation method proposed in the embodiment of the present application; the processor 14 may be configured to load and execute the program stored in the memory 13 to implement each step of the pixel compensation implementation method provided in the embodiment of the present application, and for a specific implementation process, reference may be made to the following description of a corresponding part of the method embodiment, which is not described herein again.
In the embodiment of the present application, the memory 13 may include a high-speed random access memory, and may further include a nonvolatile memory, such as at least one magnetic disk storage device or other volatile solid-state storage device. The processor 14 may be a Central Processing Unit (CPU), a control Unit MCU, an application-specific integrated circuit (ASIC), a Digital Signal Processor (DSP), an application-specific integrated circuit (ASIC), an off-the-shelf programmable gate array (FPGA) or other programmable logic devices. The specific type of memory and processor is not limited by this application and may be varied as appropriate.
It should be understood that the structure of the electronic device shown in fig. 1 does not constitute a limitation of the electronic device in the embodiments of the present application, and in practical applications, the electronic device may include more or less components than those shown in fig. 1, or some components may be combined, such as at least one output component, e.g., a speaker, a vibration mechanism, a lamp, etc.; a power management module; the various sensors, as well as at least one input component such as a camera and a sound pickup, etc., may be determined according to the product type of the electronic device and the function that can be implemented by the electronic device, which is not listed herein.
Referring to fig. 3, a schematic flowchart of an optional example of the pixel compensation implementation method provided in the present application, where the method may be applied to the electronic device described above, based on the composition structure of the electronic device described in the foregoing embodiment, as shown in fig. 3, the pixel compensation implementation method provided in this embodiment may include:
step S31, acquiring the ambient light intensity and the target color value of each sub-display area of the electronic equipment;
as can be seen from the above description of the display panel of the electronic device, the display panel includes a plurality of sub-display regions, at least one of the sub-display regions has a gray sub-pixel disposed therein, and the sub-pixel arrangement shown in fig. 2b is not limited to the above, so that the at least one sub-display region includes the disposed gray sub-pixel in addition to the original color sub-pixels (e.g., RGB sub-pixels).
In the embodiment of the present application, in order to implement high-precision adjustment on a grayscale sub-pixel and meet the requirement of display state adjustment, the number of color levels of the grayscale sub-pixel is determined based on a value range of a color value, where the color levels are used to represent an index standard of image brightness intensity, and may also be referred to as color indexes, and in a digital image processing course, the color levels are generally referred to as grayscale resolution (which may also be referred to as grayscale resolution or amplitude resolution). As can be seen, the color fullness and fineness of the image can be determined by the color gradation. It should be noted that the gradation refers to luminance, and is independent of color.
For example, the following steps are carried out: the RGB space digital image of 8-bit color respectively uses 2^8 (256) levels to represent red, green and blue sub-pixels, and the value range of the color value of each sub-pixel is [0,255 ]. In combination with the above description of the color levels and the inventive concept, the present embodiment proposes to determine the number of the color levels of the deployed gray sub-pixels for implementing pixel compensation, i.e. 1 to 256 color levels, by referring to the number of the color levels of each sub-pixel in the existing RGB sub-pixels, that is, the value range of the pixel value of the gray sub-pixel may be [1, 256].
Based on the structural characteristics of the display panel of the electronic device analyzed above, in practical application of the electronic device, the display panel is irradiated by external light, so as to realize adaptive adjustment of the display state of each display area in the display panel, the ambient light intensity can be obtained by sensing of the sensing device in the electronic device, and the intensity of the ambient light irradiated on the display panel is represented by the intensity of the ambient light. It should be noted that, the present application does not limit the manner of representing the ambient light intensity, and may be determined specifically according to the operating principle of the sensing device, and the present application is not described in detail.
The above-mentioned sensing device is taken as an example to explain, and this photosensitive element can be disposed corresponding to the different display areas of whole display panel to the light signal that the response shines on different display areas, and convert this light signal into the signal of telecommunication, thereby make display panel's different display areas produce corresponding signal of telecommunication, through the numerical value size of this signal of telecommunication, confirm that the ambient light shines the ambient light intensity size that corresponds the display area in the display panel.
In addition, in order to ensure that image distortion of display content is not caused in the process of executing pixel compensation, the target color values of the sub-display areas in the frame image are usually required to be kept unchanged, it can be understood that the target color values respectively corresponding to the sub-display areas of any frame image are usually determined according to the data source of the image, that is, after the electronic device receives the image to be displayed sent by the data source, the target color values respectively corresponding to the sub-display areas in each frame image are determined, and the target color values of the sub-display areas in the images to be displayed in different frames are often different, which is not limited in the present application.
In practical application, since one frame of image is a process of a plurality of pixel points with different color values, after the electronic device obtains any frame of image to be displayed, the electronic device can actually store the color values of the pixel points included in the image to be displayed. Therefore, in the process of displaying the image, pixel compensation needs to be performed on some pixel points of the image, so that under the condition that the display requirement of a user is met, the color value of each pixel point in the stored frame image, namely the target color value of each sub-display area, can be directly read, and the specific reading process is not described in detail in the application.
Step S32, obtaining a gray sub-pixel tone scale compensation value of a corresponding sub-display area based on the environmental light intensity and the target color value;
as described above, each sub-display region in the display panel has a corresponding gray sub-pixel, where one sub-display region corresponds to one gray sub-pixel, or multiple sub-display regions correspond to one gray sub-pixel, as the case may be, the present application is not limited thereto.
Therefore, after the ambient light intensity of each sub-display area is determined, the ambient light intensity difference between different sub-display areas can be obtained, namely, the brightness difference caused by the different ambient light intensities of the display areas after the external ambient light irradiates the display panel. This application hopes to eliminate this light and shade difference, solve its uncomfortable sense that causes to the application eye, also can make each display area's display content clearer simultaneously, to arbitrary sub-display area, under the unchangeable condition of target colour value for the last moment output of the target colour value that will output at its present moment, can be directly according to this sub-display area's ambient light intensity, confirm rather than the assorted grey level sub-pixel colour rank compensation value, can make states such as this sub-display area's display brightness more comfortable promptly, and display content clearer pixel compensation parameter, specific determination method this application does not do the restriction.
In some embodiments, the present application may utilize a professional optical device to perform multiple actual tests on a display panel of an electronic device according to different lighting conditions, so as to determine how many tone compensation values of a gray sub-pixel corresponding to a sub-display area are required to make display of the color sub-pixel of the sub-display area with a certain color value clear, comfortable in brightness, and the like under each lighting condition, for example, under illumination with a certain ambient light intensity, and for example, under an illumination of 500lux, a tone compensation value of a gray sub-pixel with a target color value of RGB (255, 0) # FF0000 of the color sub-pixel is 127, which may satisfy the above display requirements, but is not limited to each parameter value in this example.
According to the test mode, after the corresponding test results are obtained by performing pixel compensation adjustment on the display panel with a certain structure under various illumination conditions, the test results, corresponding pixel compensation parameters, illumination conditions, target color values of color sub-pixels in each sub-display area and the like can be analyzed, a corresponding adjustment curve is drawn, and the adjustment curve is mapped to specific voltage/current values of the electrical property models of the sub-pixels, so that the pixel compensation adjustment is realized according to the values. It should be noted that the present application does not limit the drawing method and the content of the adjustment curve.
The adjustment rule represented by the adjustment curve can be recorded as a pixel color level adjustment rule of the electronic device, that is, the pixel color level adjustment rule of a display panel currently installed on the electronic device is stored in a memory of the electronic device, so that in the using process of the electronic device, under the condition that the ambient light intensity of any sub-display area of the display panel changes, the processor can call the pixel color level adjustment rule at any time to determine a gray sub-pixel color level compensation value corresponding to the ambient light intensity change information of the sub-display area, that is, the problem that the ambient light intensity changes discomfort to eyes of a user and/or the displayed content is blurred can be solved.
It can be understood that, for display panels with different composition structures, especially for display panels with different sub-pixel categories included in each sub-display region, the pixel tone scale adjustment rule for the display panel may be determined in the above manner before shipment of the display panel or the electronic device, and the pixel tone scale adjustment rule may be written into a corresponding storage space of the electronic device for storage, for example, into a BIOS SPI ROM of the electronic device, so as to avoid loss of the pixel tone scale adjustment rule, but is not limited to this storage manner.
Step S33, using the compensation value of gray sub-pixel tone scale to adjust the gray sub-pixels correspondingly configured in the corresponding sub-display area, so as to change the content display state of the corresponding sub-display area.
As described above, after the gray level sub-pixel tone scale compensation value corresponding to each sub-display region of the electronic device at the current moment is determined in the above manner, the gray level positive/negative compensation adjustment of the color sub-pixel in each sub-display region can be realized accordingly, which is equivalent to the adjustment of the electrical performance parameter of the color sub-pixel, so that the adjusted value can gradually approach the parameter at the corresponding position on the adjustment curve, that is, the comfort level of the eyes of the user is gradually improved, and the display content can be made clearer. The specific adjustment manner of the gray sub-pixel is not limited in the present application, and may include, but is not limited to, adjustment of voltage/current parameters of the gray sub-pixel.
It can be understood that, in adjusting the electrical performance parameters of the gray sub-pixels and realizing the pixel tone compensation process, the display brightness of the corresponding sub-display area can be changed usually, and even the display performance parameters such as color temperature, color gamut, saturation and the like of the corresponding sub-display area can be adjusted, so that the content display state of the corresponding sub-display area can meet the display requirement, specifically, the content display brightness and definition of the sub-display area can be changed, so that a user can comfortably and clearly see the display content of the whole display area of the display panel, and the adaptability of the electronic device to the severe external illumination environment is improved.
To sum up, in the embodiment of the present application, because the display panel adopted by the electronic device is disposed with at least one gray sub-pixel in at least one sub-display area included in the display panel, and the number of color levels of the gray sub-pixel is determined based on the value range of the color value of the color sub-pixel in the sub-display area. Like this, in electronic equipment use, can acquire the ambient light intensity and the target colour value of each sub-display area, thereby based on ambient light intensity with the target colour value, obtain corresponding sub-display area's grey scale sub-pixel colour gradation compensation value, utilize this grey scale sub-pixel colour gradation compensation value, adjust the corresponding sub-display area and correspond the grey scale sub-pixel of configuration, with the content display state who changes corresponding sub-display area, with make user's eyes objective impression more comfortable, whole display panel's display content is more clear, guarantee that the user can see clearly the display content in each display area, need not additionally increase tectorial membrane such as grid membrane, also can improve the adaptability to abominable external illumination environment.
Referring to fig. 4, a schematic flow chart of another optional example of the pixel compensation implementation method proposed in the present application, this embodiment may be an optional refined implementation manner of the pixel compensation implementation method described in the foregoing embodiment, but is not limited to this refined implementation manner. As shown in fig. 4, the method may include:
s41, acquiring the ambient light intensity and the target color value of each sub-display area of the electronic equipment;
step S42, converting the ambient light intensity into an electric signal, and determining the illumination level corresponding to the electric signal;
in this application embodiment, can utilize the photosensitive element of deployment among the electronic equipment, the ambient light intensity that will sense converts the signal of telecommunication into, like this, can be with the ambient light intensity difference between the sub-display area of difference, perhaps the ambient light intensity difference of same sub-display area of different moments converts the signal of telecommunication difference that electronic equipment can discern and control into, makes things convenient for follow-up realization display state adjustment in view of the above.
Optionally, in the process of determining the illumination level of the external illumination, the present application may simulate a light sensing Device similar to a CCD (Charge-coupled Device) or a CMOS (Complementary Metal-Oxide-Semiconductor), so that subsequent adjustment and sensing may be performed according to the pixel level, and the display adjustment region may be made finer. It should be noted that the present application is not limited to the method for determining the illumination level of the external illumination.
In practical application, the illumination grade division can be realized according to the color value range of the color sub-pixels in the display panel, such as the color value range [0,255] of the RGB sub-pixels, the illumination grade can be divided into 256 grades, and the higher the illumination grade is, the higher the corresponding ambient light intensity is.
It should be understood that the light level (1-256 light intensity levels) and the color level (1-256 color level levels) of the pixel are all discrete values, but each discrete value may have a plurality of continuous parameters, for example, a light level may include a plurality of continuous ambient light intensities, and an ambient light intensity range composed of the plurality of continuous ambient light intensities is divided into a light level; similarly, a color level may comprise a plurality of consecutive pixel values, and the specific division standard is not limited in this application and may be determined as appropriate.
Therefore, the continuous environment light intensity can be sequentially divided into a plurality of sections, and a plurality of continuous environment light intensity numerical values corresponding to each section are determined as one illumination grade, namely, a first corresponding relation between different illumination grades and different environment light intensity numerical values is established. Thus, in the embodiment of the present application, when the magnitude of the electrical signal represents the magnitude of the ambient light intensity, that is, when the second corresponding relationship between different ambient light intensity values and different electrical signals is determined, the third corresponding relationship between different electrical signals and multiple illumination levels may be further determined by combining the two corresponding relationships, so as to determine the illumination level corresponding to the currently obtained electrical signal according to the third corresponding relationship. In practical application, each level of light sensation can be directly corresponding to a certain level of light and shade level compensation (i.e. gray level sub-pixel level compensation), so as to ensure the output effect of the display content of each sub-display area.
In the present application, the determination method, the representation method, the storage method, and the like of each correspondence are not limited, and may be determined as appropriate.
S43, comparing the illumination level corresponding to each sub-display area with the illumination level of the corresponding sub-display area at the previous moment to obtain the illumination level variation of the corresponding sub-display area;
in practical applications, in the case that, for any sub-display area on the display panel of the electronic device, the illumination condition irradiated to the sub-display area changes, which causes the user to be uncomfortable in watching the display content of the sub-display area, and the displayed display content is unclear, the gray sub-pixels corresponding to the sub-display area need to be adjusted according to the pixel compensation implementation method provided in the embodiment of the present application, so as to implement compensation adjustment of the sub-pixels of corresponding colors, and the specific adjustment compensation size is determined according to the variation of the illumination condition.
Therefore, after determining the illumination level corresponding to each sub-display area, the embodiment of the application may compare the illumination level with the illumination level at a previous moment in the corresponding sub-display area, determine, by the electronic device itself, the sub-display area with the changed illumination condition and the sub-display area with the unchanged illumination condition, and determine the comparison result, such as the illumination level difference, as the illumination level variation of the corresponding sub-display area.
It can be understood that, in combination with the above description of the illumination levels, in general, a plurality of continuous electrical signals correspond to the same illumination level, and the electrical signals sensed by the same sub-display area at adjacent times may change, but if the change is not large, for example, the illumination conditions at adjacent times do not change obviously, the electrical signals before and after the change may still correspond to an illumination level, in this case, the user's eyes may not feel the change, and may not make pixel compensation adjustment.
If the lighting conditions at adjacent time points change obviously, the electrical signals before and after the change corresponding to the sub-display area may correspond to different lighting levels, such as changing from the lighting level of X1 order to the lighting level of X2 order at the previous time point, but not limited to such a change amount. In this case, the user's eyes often feel obvious illumination changes, and the current illumination conditions may cause discomfort to the user's eyes, affect the definition of the display content, and so on. Therefore, the embodiment of the present application can record the illumination level variation of the sub-display area according to the condition, and use the illumination level variation as a reference for subsequently adjusting the gray sub-pixel corresponding to the sub-display area.
Step S44, comparing the target color value corresponding to each sub-display area with the target color value at the previous moment of the corresponding sub-display area to obtain the color variation of the corresponding sub-display area;
in combination with the above description about the color values of the pixels, the color values of the sub-display areas are composed of the values of the color sub-pixels included therein, and when the value of any color sub-pixel changes, the color values of the sub-display areas will change, so that the colors presented by the sub-display areas will also have differences.
Wherein, for any sub-display area, under the condition that the lighting condition is determined, that is, under the condition that the corresponding lighting level is determined, the color values of the color sub-pixels included in the sub-display area are different, such as RGB (a) i 、B i 、C i ) In addition, the comfort level requirements of the eyes of the user on the parameters of the sub-display area, such as brightness, color temperature, saturation, etc., may be different, and the color difference between the color seen by the user and the target color value of the sub-display area may also be different. As in the case of light level determination, the user views the target color RGB (A) 1 、B 1 、C 1 ) May be considered clear and comfortable, but in viewing the target color RGB (a) 2 、B 2 、C 2 ) May be considered unclear or uncomfortable.
Therefore, in practical applications, not only the eye comfort and the definition of the user watching the display content are influenced by the external lighting conditions, but also the eye comfort and the definition of the user watching the display content are influenced by the target color values of the sub-display areas. The embodiment of the application mainly has the advantages that the target color value of the same sub-display area is unchanged at adjacent moments, but the illumination condition is changed, namely under the condition that the illumination level is changed, the adjustment of the gray sub-pixels is realized according to the variable of the illumination level change, and the requirements of users on comfort and clarity in watching are met. The method for implementing pixel compensation adjustment according to color value variation is not described in detail herein.
Step S45, if the color variation is smaller than or equal to a first color threshold, calling a pixel color level adjustment rule of the electronic equipment;
as described above, the pixel level adjustment rule of the present application may be obtained by performing a plurality of measurement tests by using a professional optical instrument before the product is shipped, and summarizing and analyzing results of the plurality of measurement tests, and the detailed measurement test process is not described in detail in the present application. It should be noted that the multiple measurement tests are performed under a certain determined target color value, that is, the multiple measurement tests are used to analyze and determine the correspondence between the variation of the illumination level irradiated to each sub-display area of the display panel and the color level compensation value of the gray sub-pixel correspondingly configured to the sub-display area in order to meet the requirements of comfortable viewing and clear content of the user's eyes, it can be understood that the correspondence here is a non-linear correspondence, and the specific content is not described in detail in this application and may be determined according to the situation.
In some embodiments, as analyzed above, the above pixel tone scale adjustment rule may be represented by an adjustment curve, the slope or weighting coefficient of which is not linear, and which may be measured by an optical device in the design stage and preset to a generalized equilibrium point most suitable for human retina comfort (which may be determined by statistics and the like, and the implementation process is not described in detail), and the application does not limit the acquisition manner of the adjustment curve (i.e., the pixel tone scale adjustment rule), and which may be determined and stored before the electronic device is shipped.
Therefore, when the color variation of any sub-display area is detected to be less than or equal to the first color threshold, the target color value of the sub-display area can be considered to be substantially unchanged, direct adjustment of the color sub-pixels can be omitted, and only the adverse effect of the illumination level variation on the display state needs to be considered. The first color threshold may be a very small value, and even the color variation may be required to be equal to zero.
Step S46, determining a gray sub-pixel color level compensation value corresponding to the illumination level variation according to the pixel color level adjustment rule;
in combination with the above description about the color level of the gray sub-pixel, the color level of the gray sub-pixel is 256 discrete values, which may be denoted as Y1 to Y256, and according to the above detection, after determining the illumination level variation of any sub-display region at the current time, if the illumination level is changed from the X1 level to the X2 level, the gray sub-pixel color level compensation value corresponding to the sub-display region at the current time is determined according to the predetermined pixel color level adjustment rule capable of representing the correspondence between the illumination level variation and the gray sub-pixel color level positive/negative compensation value.
It can be seen that the gray sub-pixel tone compensation value, for example, a discrete value in Y1 to Y256, will depend on the absolute value of the difference between X1 and X2, and the value of the product of the slope or the weighting coefficient and the target color value RGB (a, B, C) on the adjustment curve, and specifically, the gray sub-pixel tone compensation value can be made as close as possible to the value, so as to improve the pixel compensation effect.
Illustratively, when the display color of a certain sub-display region is RGB (255, 0) # FF0000, i.e., standard positive red, the color is already the "most red" color value of the RGB color. If the external illumination condition is not good, for example, the illumination irradiated to the sub-display area is too bright or too dim, the display content (i.e., the display content viewed by the user) of the sub-display area may be distorted due to reasons such as contrast, and the like, and at this time, the improvement can be performed according to the conventional brightness adjustment method, but the effect is not ideal. The pixel compensation provided by the embodiment of the application can solve the problem of distortion of real content by adjusting the bright and dark color levels.
Therefore, in the above manner, when the light level of the electrical signal to be light-sensed and converted at the start time is X1 level and the target color value of the sub-display region is RGB (A1, B1, C1), the compensation value of the gray sub-pixel tone level required for the sub-display region can be determined to be Y1 level; at the next moment, the illumination level of the illumination received by the sub-display area is determined to be X2 level, and if the target color value of the sub-display area is still RGB (A1, B1, C1), a corresponding gray sub-pixel color level compensation value, such as a color level positive compensation value or a color level negative compensation value, needs to be determined according to the illumination level variation, i.e., an absolute value of a difference between X2 and X1.
And step S47, adjusting the gray sub-pixels correspondingly configured in the corresponding sub-display areas by using the gray sub-pixel tone compensation values so as to change the content display states of the corresponding sub-display areas.
As to the specific implementation process of step S47, this application is not described in detail herein, and it can be understood that, in practical applications, according to the pixel compensation implementation method provided in this application, the target color value of the sub-display area may not be changed, and the color value of the sub-display area in the eyes of the user may be changed, so that the display content of the sub-display area looks clearer to the user, and does not bring discomfort to the eyes of the user.
In summary, since a gray sub-pixel is disposed in at least one sub-display region of a display panel of an electronic device, in the using process of the electronic device, the ambient light intensity of each sub-display region is detected in real time, and after the illumination level to which the sub-display region belongs is determined, if the illumination level of a certain sub-display region at the current moment changes relative to the illumination level at the previous moment, but the target color value of the sub-display region is basically unchanged, the application can determine that the illumination level of the sub-display region changes according to the pixel color level adjustment rule, and the required gray sub-pixel color level compensation value is used to adjust the corresponding gray sub-pixel, so as to change the content display state, such as brightness, definition, of the sub-display region, and the like, so that the user feels objective and comfortable with eyes, the display content of the whole display panel is clearer, and no extra gate film or other film is needed, thereby reducing the cost of the device, and ensuring the product adaptability to the harsh external illumination environment.
In still other embodiments provided in the present application, in combination with the analysis described in the foregoing embodiments, if the color variation is greater than the first color threshold and the illumination level variation is equal to zero, that is, the illumination level is not changed, in this case, a color pixel adjustment rule of the electronic device may be invoked, so as to determine a color sub-pixel compensation value corresponding to the color variation according to the color pixel adjustment rule, and adjust the color sub-pixels correspondingly configured in the corresponding sub-display regions by using the color sub-pixel compensation value, specifically, electrical performance parameters of the color sub-pixels, such as voltage/current values, may be adjusted, and a specific adjustment implementation method is not limited.
The process of acquiring the color pixel adjustment rule is similar to the process of acquiring the pixel tone scale adjustment rule, and the difference is as follows: when the color pixel adjustment rule is obtained, the illumination level is used as a constant, the color value of each sub-display area is used as a variable, measurement and analysis are performed for multiple times by using professional optical equipment, and under the condition that a certain illumination level is unchanged, the color value of each sub-display area changes, the adjustment amount of each color sub-pixel contained in the corresponding sub-display area reaches, the adjustment termination condition can be met, if the comfortable area of eyes of a user and the clear area of contents are reached, and the final adjustment amount is recorded as the color sub-pixel compensation value of the sub-display area under the illumination level.
Then, after obtaining a plurality of measurement results according to the analysis and measurement manner, analyzing the color variation, the illumination level, and the color sub-pixel compensation value corresponding to the plurality of measurement results, so as to obtain the color pixel adjustment rule applicable to the scene, but not limited to the color pixel adjustment rule obtaining manner.
Referring to fig. 5, a schematic flow chart of a further alternative example of a pixel compensation implementation method proposed in the present application, an embodiment of the present application may be a further alternative refined implementation manner, or an extended implementation manner, of the pixel compensation implementation method described in the foregoing embodiment, as shown in fig. 5, the method may include:
s51, acquiring a content to be displayed;
step S52, determining target color values of all sub-display areas of the electronic equipment according to the content to be displayed, and outputting the content to be displayed;
step S53, acquiring the ambient light intensity of each sub-display area of the electronic equipment during the period of outputting the content to be displayed;
it can be understood that, during the usage of the electronic device, the electronic device displays the content, and the display panel is usually illuminated by the external light, and the application does not limit the execution process of the above steps, as the case may be.

Step S54, determining the illumination level variation and the color variation of the corresponding sub-display area based on the environmental light intensity and the target color value;
step S55, if the color variation is larger than the first color threshold and the illumination level variation is larger than zero, acquiring a gray sub-pixel tone scale compensation value corresponding to the illumination level variation and a color sub-pixel compensation value corresponding to the color variation;
in some embodiments, the manner of obtaining the gray sub-pixel tone scale compensation value corresponding to the illumination level variation and the process of obtaining the color sub-pixel compensation value corresponding to the color variation may refer to the description of the corresponding parts of the above embodiments, which is not repeated herein.
Wherein, according to different adjustment rules, the in-process of confirming grey level sub pixel colour gradation compensation value and colour sub pixel compensation value need be mutually in coordination to confirm to guarantee to carry out pixel compensation according to these two compensation values, can improve the definition of the display content in corresponding sub display area, and the comfort of eyes when the user watches.
In still other embodiments, when the illumination level of a certain sub-display area changes and the corresponding target color also changes significantly at an adjacent time of the electronic device, and the adjustment rule applicable to the situation is determined according to the above-mentioned multiple measurement statistical analysis manner, the illumination level variation and the target color worth color variation are both used as variables in the analysis process to analyze the simultaneous changes of the illumination level variation and the target color worth color variation, and influence on the content display state in the sub-display area is analyzed, so that the adjustment rule applicable to the scene is obtained by combining the multiple test measurement results.
It can be understood that the adjustment rule obtained in this embodiment is different from the single-variable pixel tone scale adjustment rule and the color pixel adjustment rule, and belongs to a double-variable adjustment rule, so that the adjustment rule can be directly invoked when it is determined that both the illumination level and the target color value are changed, and when it is determined that the content display state requirement of the sub-display area is satisfied, the required gray sub-pixel tone scale compensation value and/or the required color sub-pixel compensation value are/is determined, and the specific determination process is not described in detail.
Step S56, using the gray sub-pixel tone compensation value and the color sub-pixel compensation value to perform a coordinated adjustment on the plurality of color sub-pixels included in the corresponding sub-display area and the correspondingly configured gray sub-pixels, so as to change the content display state of the corresponding sub-display area.
As described above, in the embodiment of the present application, in the case that the gray sub-pixel color level compensation value and the color sub-pixel compensation value of any sub-display area are determined in the above manner, the gray sub-pixel color level compensation value and/or the color sub-pixel compensation value may be used to perform coordinated adjustment on a plurality of color sub-pixels included in the corresponding sub-display area and gray sub-pixels configured correspondingly, so as to change the content display state of the corresponding sub-display area, thereby solving the technical problem that, under a poor lighting condition, part of the display area of the electronic device is too bright and part of the display area is too dark, which causes discomfort when a user views the display content, and even the whole display content cannot be seen clearly.
