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, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
In the related art, since the display screen is provided with the plurality of different light-emitting areas, when the display screen displays images, if the brightness difference between the plurality of different light-emitting areas is too large, the brightness of the images displayed by the display screen is not uniform enough, and the quality of the images displayed by the display screen is reduced.
In order to solve the technical problem, embodiments of the present application provide a display control method, an apparatus, an electronic device, and a storage medium. The display control method can reduce the brightness difference between different areas of the display screen and improve the display quality. The display method can be applied to various electronic equipment with screens such as televisions, computers and displays.
Referring to fig. 1, fig. 1 is a first flowchart of a display control method according to an embodiment of the present disclosure. The display control method may include the steps of:
110. the first area on the display screen is divided into a plurality of second areas.
In some embodiments, the display screen may set a plurality of different brightness partitions, and the display screen may perform Local dimming (Local dimming) for the plurality of brightness partitions, so that the static contrast of the display screen is higher when the display screen displays a picture, and the image quality displayed by the display screen is better.
In some cases, if there are fewer luminance partitions and each luminance partition contains more pixels, the difference between the average backlight value and the maximum backlight value in one luminance partition is often large, and at this time, the backlight value of each luminance partition can be directly adjusted, so that the light leakage effect between different luminance partitions is reduced, and the display screen has higher display quality when displaying a picture.
It should be noted that the backlight value mentioned in the embodiment of the present application is a backlight PWM (Pulse Width Modulation) value in the corresponding luminance partition, where the backlight PWM value can be understood as a duty ratio between a high Pulse and a low Pulse of the luminance partition when displaying. When the backlight value is higher, the display brightness corresponding to the brightness partition is brighter. When the backlight value is low, the display brightness corresponding to the brightness partition is dark.
However, in some cases, if there are more luminance partitions and there are fewer pixels in each luminance partition, the average backlight value and the maximum luminance value in one luminance partition may be the same, resulting in higher luminance corresponding to the luminance partition, and if there is a luminance partition with a smaller backlight value beside the luminance partition, the luminance corresponding to the luminance partition with the smaller backlight value is lower, resulting in larger luminance difference between the two luminance partitions due to larger difference between the backlight values corresponding to the two luminance partitions. When human eyes observe the display screen, because the brightness difference of the two brightness partitions is large, an obvious halo effect can be seen on the display screen, and the display quality of the display screen is poor.
On the basis, the electronic device may determine one brightness partition as the first region among the plurality of brightness partitions, and then divide the first region to obtain a plurality of second regions, that is, the second regions are sub-regions of the first region.
In some embodiments, before dividing a first area on a display screen into a plurality of second areas, the electronic device may determine the number of pixels of each luminance partition provided on the display screen, and determine a luminance area as the first area if the number of pixels of a luminance partition is less than a preset number of pixels.
In some embodiments, after the first region is determined, the area of the first region may be determined, and then the first region may be divided into a plurality of second regions according to the area of the first region, for example, in the case that the area of the first region is smaller, the first region may be divided into 3 × 3 second regions, that is, 9 second regions. In the case that the first region has a larger area, the first region may be divided into 9 × 9 second regions, that is, 81 second regions.
It should be noted that, the division of the first area may be set according to actual situations, for example, in the case that the computing power of the electronic device processor is low, the first area may be divided into 3 × 3 second areas. The electronic device may further divide the first region into different numbers of second regions, such as 5 × 5, 7 × 7, and the like.
120. And determining a target area in the plurality of second areas, and determining a first backlight value corresponding to the target area.
In some embodiments, a second region at the midpoint among the plurality of second regions may be the target region. As shown in fig. 2, fig. 2 is a schematic view of a second region provided in the present application, wherein in the second region 3 × 3, the second region E may be taken as a target region.
It should be noted that, in the plurality of second areas, a target area may also be selected according to a requirement, for example, the second area a in fig. 2 is selected as the target area.
After determining the target area, the electronic device may determine a first backlight value for the target area. The electronic device may directly calculate a backlight value of the target area and determine the backlight value as the first backlight value.
In some embodiments, the electronic device may further calculate a third backlight value corresponding to the first region, and then determine the third backlight value as the first backlight value of the target region.
In some approaches, the electronic device may first determine an average backlight value and a maximum backlight value for the first region. And then determining a backlight weight value corresponding to the first area, and determining a third backlight value corresponding to the first area according to the backlight weight value, the average backlight value and the maximum backlight value.
Specifically, the following calculation formula can be adopted:
Duty|Seg(i,j)＝αPix(avg)+(1-α)Pix(max)
wherein pix (avg) is an average backlight value of the first region, pix (max) is a maximum backlight value of the first region, α is a backlight weight value corresponding to the first region, and a value range of α is between 0 and 1. Duty | Seg (i, j) is the third backlight value corresponding to the first region, i represents row, j represents column, and (i, j) represents the backlight in the ith row and jth column.
It should be noted that the backlight weight value may be set according to actual requirements, for example, in order to prevent the brightness of the entire first region from being too bright, the backlight weight value may be set to be larger. To make the brightness of the entire first region brighter, the backlight weight value may be set smaller.
130. And acquiring second backlight values respectively corresponding to other second areas except the target area in the plurality of second areas.
In some embodiments, the second backlight values corresponding to the second areas except the target area in the plurality of second areas may be calculated in the above manner.
For example, as shown in fig. 2, if the second area E is determined as the target area, the first backlight value of the target area is Duty | Seg (I, j), and then the second backlight value Duty | Seg (I-1, j-1) of the second area a, the second backlight value Duty | Seg (I, j-1) of the second area B, the second backlight value Duty | Seg (I +1, j-1) of the second area C, the second backlight value Duty | Seg (I-1, j) of the second area D, the second backlight value Duty | Seg (I +1, j) of the second area F, the second backlight value Duty | Seg (I-1, j +1) of the second area G, the second backlight value Duty | G (I, j +1) of the second area H, and the second backlight value Duty | Seg (I, j +1) of the second area I are calculated.
140. And determining a target backlight value corresponding to the first area according to the first backlight value and the second backlight value.
In some embodiments, after determining the first backlight value of the target area and the second backlight values corresponding to the plurality of second areas, the electronic device may add the first backlight value and the plurality of second backlight values to obtain an added value, and then divide the added value by the number of the second areas to obtain the target backlight value corresponding to the first area.
In some embodiments, the electronic device may further determine an adjustment parameter corresponding to the first region, and then determine a target backlight value corresponding to the first region according to the adjustment parameter, the first backlight value, and the second backlight value.
For example, the electronic device may first determine the target number of the second areas excluding the target area among the plurality of second areas, and then determine the first target value according to the first backlight value and the adjustment parameter; adding the first target value and the second backlight value to obtain a second target value; adding the target number and the adjusting parameters to obtain a third target value; and finally, dividing the second target value by the third target value to obtain a target backlight value corresponding to the first area.
In the embodiment of the application, the first area is divided into the plurality of second areas, and then the target backlight value of the first area is calculated through the backlight values of the plurality of second areas, so that the brightness difference of the first area relative to the brightness of other adjacent brightness partitions is not too large, the phenomenon of uneven brightness of a picture finally displayed by a display screen is avoided, and the display quality of the display screen is finally improved.

In some embodiments, before dividing a first area on a display screen into a plurality of second areas, the electronic device may determine the number of pixels of each luminance partition provided on the display screen, and determine a luminance area as the first area if the number of pixels of a luminance partition is less than a preset number of pixels.
In some embodiments, after the first region is determined, the area of the first region may be determined, and then the first region may be divided into a plurality of second regions according to the area of the first region, for example, in the case that the area of the first region is smaller, the first region may be divided into 3 × 3 second regions, that is, 9 second regions. In the case that the first region has a larger area, the first region may be divided into 9 × 9 second regions, that is, 81 second regions.
It should be noted that, the division of the first area may be set according to actual situations, for example, in the case that the computing power of the electronic device processor is low, the first area may be divided into 3 × 3 second areas. The electronic device may further divide the first region into different numbers of second regions, such as 5 × 5, 7 × 7, and the like.

And then determining a backlight weight value corresponding to the first area, and determining a third backlight value corresponding to the first area according to the backlight weight value, the average backlight value and the maximum backlight value.
Specifically, the following calculation formula can be adopted:
Duty|Seg(i,j)＝αPix(avg)+(1-α)Pix(max)
wherein pix (avg) is the average backlight value of the first area, pix (max) is the maximum backlight value of the first area, α is the backlight weight value corresponding to the first area, Duty | Seg (i, j) is the third backlight value corresponding to the first area, i represents a row, j represents a column, and (i, j) represents the backlight of the ith row and the jth column.

203. The number of targets of the second area other than the target area among the plurality of second areas is determined.
In some embodiments, the target area is one of the plurality of second areas, and removing the target area from the plurality of second areas allows the target number of remaining second areas to be determined. As shown in fig. 2, in the second region 3 × 3, the number of the second regions is 9, and when one target region is removed, 8 second regions are left, and the number of targets is 8.
204. And determining a target backlight value corresponding to the first area according to the target number, the adjustment parameter, the first backlight value and the second backlight value.
In some embodiments, the electronic device may determine a first target value based on the first backlight value and the adjustment parameter; adding the first target value and the second backlight value to obtain a second target value; adding the target number and the adjusting parameters to obtain a third target value; and finally, dividing the second target value by the third target value to obtain a target backlight value corresponding to the first area.

Duty|Seg(i,j)’＝[Duty|Seg(i-1,j-1)+Duty|Seg(i,j-1)+Duty|Seg(i+1,j-1)+
Duty|Seg(i-1,j)+XDuty|Seg(i,j)+Duty|Seg(i+1,j)+Duty|Seg(i-1,j+1)+
Duty|Seg(i,j+1)+Duty|Seg(i+1,j+1)]/(X+N)
