Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without inventive step, are within the scope of the present application.
The embodiment of the application provides a display screen processing method which can be applied to electronic equipment. The electronic device may be a smartphone, a tablet, a gaming device, an Augmented Reality (AR) device, a data storage device, an audio playback device, a video playback device, a notebook, a desktop computing device, a wearable device such as a watch, glasses, a helmet, an electronic bracelet, an electronic necklace, an electronic garment, or the like, having a display screen.
Referring to fig. 1, fig. 1 is a first flowchart illustrating a display screen processing method according to an embodiment of the present disclosure. The display screen processing method specifically comprises the following steps:
101, acquiring first gray scale information of a first display area and second gray scale information of a second display area.
Please refer to fig. 2, wherein fig. 2 is a schematic structural diagram of a display screen and an optical element according to an embodiment of the present disclosure. The display screen 610 includes adjacent first and second display regions 612, 614, the pixel density in the first display region 612 being greater than the pixel density in the second display region 614. The second display region 614 has a lower pixel density than the first display region 612, and corresponding driving circuits are also less than the first display region 612, and the second display region 614 may have a higher light transmittance than the first display region 612. The second display region 614 allows the optical element 616 to acquire enough light signals through the second display region 614 to perform the corresponding function. For example, the optical element proximity sensor may emit a detection signal through the second display region and receive a reflection signal through the second display region, thereby obtaining an accurate proximity state. For another example, an optical element camera may be used to acquire an image of the optical signal transmitted through the second display region. The second display region has a low pixel density, and the density of a driving circuit connected to the pixel is also low, and the optical signal having a light transmittance sufficient for the second display region functions. The light transmittance of the second display region may be greater than 50%, 60%, or 70%, etc.
It should be noted that the second display region may be further processed to improve light transmittance. For example, the driving lines are made of transparent ITO instead of metal, and some film layers are made of highly transparent material instead of metal, which is not limited herein. The first display area and the second display area may be two adjacent display areas of the same display screen.
The pixel density of the second display area is lower, if the second display area and the first display area adopt the same driving signal, the brightness of the second display area and the first display area has obvious difference, the brightness of the second display area is lower than that of the first display area, and the second display area is obviously darker than that of the first display area. At this time, the method of the embodiment of the application can improve the luminance difference between the second display area and the first display area, and specifically, first gray scale information of the first display area and second gray scale information of the second display area are obtained. The gray scale represents the gradation levels with different brightness from the darkest to the brightest, and the more gradation levels, the more exquisite the picture effect can be presented. The first gray scale information includes brightness corresponding to different gradation levels, and the second gray scale information also includes brightness corresponding to different gradation levels. It should be noted that, the corresponding gradation levels of the first gray scale information and the second gray scale information may be the same or different. Illustratively, the first gradation information includes 64 gradation levels, the second gradation information includes 32 gradation levels, and the gradation levels of the first display region and the second display region are different and the brightness corresponding to the different gradation levels is also different. Further illustratively, the first gradation information and the second gradation information each include 64 gradation levels. Because the first display area and the second display area have different pixel densities and different maximum luminances, the luminances of the corresponding hierarchical levels are also different.
102, obtaining a first gray scale difference value according to the first gray scale information and the second gray scale information.
After different first gray scale information and second gray scale information are obtained, a first gray scale difference value of the first gray scale information and the second gray scale information is obtained through calculation.
And if the gradation levels of the first gradation information and the second gradation information are the same, obtaining the brightness difference value of each gradation level. In the high-brightness area, the brightness of one level in the second gray scale information corresponds to the brightness of a plurality of levels in the first gray scale information; in the middle brightness area, the brightness of one level in the second gray scale information corresponds to the brightness of one level in the first gray scale information; in the low luminance region, the luminance of a plurality of gradation levels in the second gradation information corresponds to the luminance of one gradation level in the first gradation information.
If the first gray scale information and the second gray scale information have different hierarchical levels and the first gray scale information has more hierarchical levels, the brightness of one hierarchical level in the second gray scale information corresponds to the brightness of one or more hierarchical levels in the first gray scale information. For example, also with the luminance of the second gradation information as a standard, the second gradation information includes 32 gradation levels, the first gradation information includes 64 gradation levels, and the luminance of one gradation level in the second gradation information corresponds to the luminance of two gradation levels in the first gradation information. Of course, different correspondence strategies may be employed in different luminance regions. For example, at the level 1-10 of the second gradation information, the luminance of one gradation level in the second gradation information corresponds to the luminance of one gradation level in the first gradation information, that is, corresponds to the level 1-10 in the first gradation information. At levels of 11-22 levels of the second gradation information, the luminance of one level in the second gradation information corresponds to the luminance of two levels in the first gradation information, i.e., to levels of 11-44 levels in the first gradation information. At the 23-21 gradation levels, the luminance of one gradation level in the second gradation information corresponds to the luminance of three gradation levels in the first gradation information, i.e., corresponds to the 45-64 gradation levels in the first gradation information.
103, adjusting at least one brightness voltage curve in the first display area and the second display area according to the first gray scale difference value, so that the adjusted gray scale difference value of the first display area and the second display area is smaller than the first gray scale difference value.
After the first gray scale difference value of the first display area and the second display area is obtained, the brightness voltage (gamma) curve of the first display area and/or the second display area can be adjusted, so that the brightness of the first display area and the brightness of the second display area are the same or close to each other under each gray scale level, the brightness display effect of the first display area and the brightness display effect of the second display area are close to each other, and the display difference of the first display area and the second display area is reduced.
If the first display area and the second display area share one gamma curve, the pixel density of the two display areas is different, the maximum brightness is definitely different (the number of pixels in the unit area of the second display area is less), and the gray scale performance of the two display areas cannot be considered. For example, the gamma curve makes the first display region have 64 gradation levels, the maximum brightness of the second display region is smaller, the high brightness part of the gamma curve is completely unused, and the gradation level is affected, and the second display region may have only 40 gradation levels using the gamma curve. Illustratively, the gradation levels of the first gradation information and the second gradation information are the same, so that the two display areas respectively use one gamma curve, which can satisfy that the two display areas can both have better gradation effect (for example, both have 64 gradation levels), the display effect of the two display areas is better, and the display areas can not be blurred due to insufficient gradation in a darker area because of insufficient gradation, and the luminance difference of the two display areas can be reduced, so that the two display areas transition more naturally, and the difference between the two display areas is reduced. For example, the luminance range of several gradation levels in which the luminance of the first gradation information is the largest is enlarged, and the luminance range of several gradation levels in which the luminance of the second gradation information is the largest is minimized.
Referring to fig. 3, fig. 3 is a schematic flowchart of a second display screen processing method according to an embodiment of the present application. The display screen processing method specifically comprises the following steps:
first gray scale information of a first display area and second gray scale information of a second display area are obtained 201.
202, obtaining a first gray scale difference value according to the first gray scale information and the second gray scale information.
And 203, adjusting at least one brightness voltage curve in the first display area and the second display area according to the first gray scale difference value, so that the adjusted gray scale difference value of the first display area and the second display area is smaller than the first gray scale difference value.
The steps corresponding to 201-203 in this embodiment are the same as the steps corresponding to 101-103 in the above embodiment, and are not described herein again.
204, first color information of the first display area and second color information of the second display area are acquired.
Referring to fig. 4 and 5, fig. 4 is a schematic diagram illustrating an arrangement of a plurality of sub-pixels of a first pixel in a first display area according to an embodiment of the present disclosure; fig. 5 is a schematic view illustrating an arrangement of a plurality of sub-pixels of a second pixel in a second display region according to an embodiment of the present disclosure. The first display region includes a plurality of first pixels 622, the second display region includes a plurality of second pixels 642, and an arrangement manner of a plurality of sub-pixels 624 of the first pixels 622 is different from an arrangement manner of a plurality of sub-pixels 644 of the second pixels 642. Illustratively, the plurality of sub-pixels 624 of the first pixel 622 of the first display region are in a Pentile arrangement, and the plurality of sub-pixels 644 of the second pixel 642 of the second display region are in a standard RGB arrangement. In another example, the plurality of sub-pixels of the first pixel of the first display region may also be in a Pentile arrangement, and the plurality of sub-pixels of the second pixel of the second display region may also be in a Delta arrangement. Because the arrangement modes of the sub-pixels of the first display area and the second display area are different, if the same color driving signal is adopted by the second display area and the first display area, the colors of the second display area and the first display area are obviously different.
At this time, the method of the embodiment of the present application may improve the color difference between the second display area and the first display area, specifically, first obtain the first color information of the first display area and the second color information of the second display area.
A first color difference value of the first color information and the second color information is obtained 205.
After the first color information and the second color information are acquired, a first color difference value of the first color information and the second color information is acquired. Specifically, the display screen performs color mixing display by using three primary colors of RGB, that is, the display screen includes three pixels of RGB, and the first color difference value includes a difference value of three colors of RGB. Wherein, the RGB colors can be mixed into a plurality of colors, such as yellow, pink, etc., and the first color difference value can also include the difference value of other mixed colors.
And 206, adjusting the color display mode of at least one of the first display area and the second display area according to the first color difference value, so that the color difference value of the adjusted first display area and the second display area is smaller than the first color difference value.
After the first color difference value of the first display area and the second display area is obtained, the color display mode of the first display area and/or the second display area can be adjusted, so that various colors of the first display area and the second display area are the same or approximate, the color display effect of the first display area and the second display area is approximate, and the color display difference of the first display area and the second display area is reduced.
According to the embodiment of the application, the gamma curves and the color display modes of the first display area and/or the second display area are adjusted, so that the brightness and the color of each gray scale of the first display area and the second display area are the same or close to each other, the brightness display effect and the color display effect of the first display area and the second display area are close to each other, and the brightness display difference and the color display difference of the first display area and the second display area are reduced.
Wherein adjusting the display mode of at least one of the first display area and the second display area according to the first color difference value may include:
acquiring a corresponding target pixel rendering mode according to the first color difference value and the arrangement mode of a plurality of sub-pixels in the second pixel; and
the second display area is displayed using a target pixel rendering mode.
An appropriate Pixel Rendering manner may be selected from a plurality of Pixel Rendering manners (SPR) as a target Pixel Rendering manner according to an arrangement manner of a plurality of Sub-pixels in a second Pixel of the second display region. For example, if the plurality of sub-pixels of the second pixel in the second display region are arranged in Pentile, the first pixel rendering manner is a target pixel rendering manner, and if the plurality of sub-pixels of the second pixel in the second display region are arranged in standard RGB, the second pixel rendering manner is a target pixel rendering manner. And if the plurality of sub-pixels of the second pixel in the second display area are arranged in Delta, the third pixel rendering mode is a target pixel rendering mode. The target pixel rendering mode can be adjusted by combining the first color difference value. Illustratively, the drive signal (at least one of the drive voltage, the drive current, the drive period, etc.) of the R pixel is increased, and the drive signal (at least one of the drive voltage, the drive current, the drive period, etc.) of the B pixel is decreased. Of course, the driving signals of one or two or three of the pixels may also be adjusted according to the first color difference value. And the second display area is displayed by using the adjusted target pixel rendering mode.
Wherein the displaying of the second display area using the target pixel rendering mode may include:
acquiring first display information of a target pixel in a second display area and a plurality of second display information of a plurality of reference pixels around the target pixel;
determining target display information of the target pixel according to the first display information and the plurality of second display information; and
and driving the target pixel to display according to the target display information.
If the sub-pixels of the second pixel in the second display region are arranged in the standard RGB and have a low pixel density, the granular sensation is easily caused. The target pixel of the embodiment of the application not only comprises the first display information of the target pixel, but also comprises a plurality of second display information of a plurality of peripheral reference pixels. And ensuring that each target pixel can keep contact with surrounding pixel points, thereby eliminating granular sensation in the second display area.
Determining the target display information of the target pixel according to the first display information and the plurality of second display information may specifically include: and obtaining target display information according to different weights of the first display information and the plurality of second display information.
The target pixel is any one second pixel in the second display area, and the reference pixel is a second pixel around the target pixel. For example, please refer to fig. 6, where fig. 6 is a schematic diagram of a pixel rendering method according to an embodiment of the present disclosure. The figure shows the positions and coordinates of the second pixels of the 9 second display areas, wherein the target pixel is a pixel corresponding to the coordinates (0,0) in the figure, and the reference pixels are four reference pixels at the upper, lower, left and right sides of the periphery of the target pixel. The weight of the first display information of the target pixel is 0.5, and the weight of each reference pixel is 0.125. And finally, the obtained target display information of the target pixel is obtained by calculating according to different weights of the original first display information of the target pixel and the second display area information of the reference pixel. In another example, the target pixel is any one of the pixels in the second display region, and the reference pixels are eight reference pixels connected to the periphery of the target pixel. The weight of the first display information of the target pixel is 0.5, and the weight of the second display information of each reference pixel is 0.0625. In another example, as shown in fig. 7, the target pixel is a pixel corresponding to coordinates (0,0) in the figure, and the reference pixels are pixels located right, left, below and at one corner of the target pixel. The weight of the first display information of the target pixel is 0.5, and the weight of each reference pixel is 0.125. It should be noted that the above-mentioned weight values are exemplary, and the weight of the display information of each pixel may be set as needed. The first display information and the second display information may include at least one of a driving voltage, a driving current, a driving time period, and the like.
Referring to fig. 8, fig. 8 is a third flowchart illustrating a display screen processing method according to an embodiment of the present disclosure. The display screen processing method specifically comprises the following steps:
301, acquiring first gray scale information of a first display area and second gray scale information of a second display area.
302, a first gray scale difference is obtained according to the first gray scale information and the second gray scale information.
The steps corresponding to 301-302 in this embodiment are the same as the steps corresponding to 101-102 in the above embodiment, and are not described herein again.
303, adjusting the brightness voltage curve of the transition region according to the first gray scale difference value, so that the gray scale difference value between the adjusted transition region and the second display region is smaller than the first gray scale difference value.
Referring to fig. 9, fig. 9 is another schematic structural diagram of a display screen and an optical element according to an embodiment of the present disclosure. The first display area 612 includes a transition area 622 adjacent to the second display area 614, and the first display area 612 further includes a main display area 624 other than the transition area 622, the transition area 622 being disposed between the main display area 624 and the second display area 614.
The brightness voltage (gamma) curve of the transition region is adjusted through the first gray scale difference value, so that the brightness of the transition region and the brightness of the second display region are the same or close to each gray scale level, and the brightness difference is relatively different because the pixel arrangement modes of the transition region and the main display region are the same. Through the buffering of the transition area, the whole display effect of the display screen can be transited uniformly. For example, the brightness of the transition region is between the second display region and the main display region, and the transition region is brighter than the second display region but darker than the main display region, so that the second display region can be well transitioned to the main display region. The transition region may sacrifice some of the brightness detail (e.g., more gray scale levels than the second display region but less gray scale levels than the main display region), or the brightness of the transition region for each gray scale level may be between the second display region and the main display region. Three gamma curves may be provided, and the second display region, the transition region and the main display region each have one gamma curve.
304, the first color information of the first display region and the third color information of the transition region are acquired.
The arrangement of the plurality of sub-pixels of the first pixel of the first display region is different from the arrangement of the plurality of sub-pixels of the second pixel of the second display region. Illustratively, the plurality of sub-pixels of the first pixel of the first display region are in a Pentile arrangement, and the plurality of sub-pixels of the second pixel of the second display region are in a standard RGB arrangement. In another example, the plurality of sub-pixels of the first pixel of the first display region may also be in a Pentile arrangement, and the plurality of sub-pixels of the second pixel of the second display region may also be in a Delta arrangement.
And 305, obtaining a second color difference value according to the first color information and the third color information.
After the first color information and the third color information are acquired, a second color difference value of the first color information and the third color information is acquired. Specifically, the display screen performs color mixing display by using three primary colors of RGB, that is, the display screen includes three pixels of RGB, and the second color difference value includes a difference value of three colors of RGB. Wherein, the RGB colors can be mixed into a plurality of colors, such as yellow, pink, etc., and the first color difference value can also include the difference value of other mixed colors.
And 306, adjusting the display mode of the transition region according to the second color difference value, so that the color difference value between the adjusted transition region and the second display region is smaller than the second display difference value.
After the second color difference value between the transition display area and the second display area is obtained, the color display mode of the transition area can be adjusted, so that various colors of the transition area and the second display area are the same or approximate, the color display effect of the transition area and the second display area is approximate, and the color display difference between the transition area and the second display area is reduced.
