Fig. 1 schematically illustrates an application scenario of a display method according to an embodiment of the present disclosure. It should be noted that fig. 1 is only an example of a scenario in which the embodiments of the present disclosure may be applied to help those skilled in the art understand the technical content of the present disclosure, but does not mean that the embodiments of the present disclosure may not be applied to other devices, systems, environments or scenarios.
As shown in fig. 1, an electronic device 100 may be included in the application scenario. The electronic device 100 may be, for example, a full-screen mobile phone, a tablet computer, or any other electronic device including a display screen.
Electronic components such as a camera of the electronic apparatus 100 may be disposed behind the display screen so as to be hidden inside the electronic apparatus 100. As shown in fig. 1, for example, a camera of the electronic device may be hidden behind one display area 110 in the display screen.
According to the embodiment of the present disclosure, a camera is placed behind the display area 110, and in order to improve the light transmittance of the display area 110, the pixel density of the display area 110 may be less than that of other areas on the display screen. However, the pixel density of the display area 110 is different from that of other areas, so that the display effect of the display area 110 is different from that of other areas.
The present disclosure provides a display method, which may reduce a difference between a display effect of the display area 110 and display effects of other areas, make the display effect of the display screen more natural, and improve user experience.
Fig. 2 schematically shows a flow chart of a display method according to an embodiment of the present disclosure.
As shown in fig. 2, the method includes operations S201 to S204.
In operation S201, a display screen is lit in response to a lighting instruction.
According to an embodiment of the present disclosure, the lighting instruction may be, for example, a lighting instruction generated by a user clicking an unlock button when the electronic device is in a screen lock state. Alternatively, the lighting instruction may be, for example, an instruction for controlling the electronic device to display the content on the display screen.
In operation S202, a target brightness value is obtained.
The target brightness value may be, for example, a brightness value of the display screen determined by the electronic device according to the brightness of the current environment. The target brightness may be adapted to the brightness of the current environment to enable the user to see the display content on the display screen clearly.
According to the embodiment of the disclosure, for example, a corresponding relationship table between the brightness of the current environment and the target brightness value may be stored in the electronic device, and the electronic device determines the target brightness value by sensing the brightness of the current environment and looking up the corresponding relationship table.
According to the embodiment of the present disclosure, the target brightness value may also be set by the user himself, for example. And under the condition that the target brightness value is set by the user, the electronic equipment acquires the target brightness value set by the user.
In operation S203, a target grayscale value of the first region and a target grayscale value of the second region are determined based on the target luminance values. The first area and the second area belong to a display area of a display screen. The first region corresponds to the first pixel, and the second region corresponds to the second pixel. The density of the first pixels of the first region is less than the density of the second pixels of the second region. The target gray-scale value of the first area is a gray-scale value obtained by accumulating a first compensation value, and the first compensation value is used for reducing the difference between the brightness of the first area and the brightness of the second area caused by the difference between the pixel density of the first area and the pixel density of the second area.
According to an embodiment of the present disclosure, the target gray scale value may be a gray scale value that the pixel should output in order for the display screen to reach the target brightness. According to the embodiments of the present disclosure, since different colors are output even at the same gray scale value, the luminance may be visually different for the different colors. For example, blue may be visually brighter than yellow. Therefore, in order to achieve the same target brightness of the display screen, pixels outputting different colors may correspond to different target gray scale values. For example, to achieve a target brightness for the display screen, the target gray scale value for the pixel outputting blue may be less than the target gray scale value for the pixel outputting white.
Specifically, for example, the target brightness of the electronic device may be half of the maximum brightness that can be achieved by the electronic device, and when an image is output on the display screen, the electronic device needs to determine the target gray-scale value of each pixel according to the image that needs to be output currently and the target brightness that needs to be achieved. For example, the image may include yellow, the pixel in the display screen may be caused to output yellow by controlling the ratio of R, G, B, and the electronic device may determine to output yellow and the luminance of the display screen reaches half of the maximum luminance, for example, by looking up the correspondence between yellow, the target luminance, and the target gray scale value, and output the target gray scale value for the yellow pixel. For another example, the image may further include purple, the pixel displaying purple outputs purple by controlling the proportion of R, G, B, and the electronic device may determine to output purple by querying the corresponding relationship between purple, the target brightness and the target gray-scale value, and the brightness of the display screen reaches half of the maximum brightness, and output the target gray-scale value of the pixel displaying purple.
In operation S203, a target gray-scale value of each pixel may be determined according to the target brightness value and the color output by each pixel. And the target gray-scale value of the pixel of the first area and the target gray-scale value of the pixel of the second area are different for the same color due to the difference of the pixel density of the second area and the first area.
According to an embodiment of the present disclosure, for example, in the electronic device 100 shown in fig. 1, the first region may be, for example, the display region 110. The second area may be, for example, an area of the electronic device 100 other than the display area 110. The pixel density of the first region is less than the pixel density of the second region.
According to the embodiment of the disclosure, since the pixel density of the first region is less than that of the second region, if the pixels in the first region and the second region output the same gray-scale value, the luminance of the first region is less than that of the second region, which results in inconsistent display effect of the electronic device 100.
In order to make the display effects of the first and second regions of the electronic device 100 consistent, a target gray scale value of the first region is determined based on a target brightness value, and a target gray scale value of the second region is determined based on the target brightness value in operation S203. The target gray-scale value of the first area is a gray-scale value obtained by accumulating a first compensation value, and the first compensation value is used for reducing the difference between the brightness of the first area and the brightness of the second area caused by the difference between the pixel density of the first area and the pixel density of the second area.
For example, in order to make the luminance of the display area 110 of the electronic device 100 reach a target luminance value, that is, the luminance of the other areas except the display area 110 are consistent, a target gray-scale value of the first area and a target gray-scale value of the second area may be determined according to the target luminance value, respectively, in operation S203. And the target gray-scale value of the first area is the gray-scale value after the first compensation value is accumulated.
Specifically, for example, the target luminance is reached when the target gray-scale value output by the second region is 128, and the target gray-scale value output by the first region for reaching the target luminance may be 128+ offset. Wherein, the offset is the first compensation value, and the offset is greater than 0.
According to an embodiment of the present disclosure, for example, a first correspondence table and a second correspondence table may be stored in the electronic device. The first corresponding table is used for indicating that the pixels of the first area output target gray-scale values corresponding to different colors under different target brightness, and the second corresponding table is used for indicating that the pixels of the second area output target gray-scale values corresponding to different colors under different target brightness.
Specifically, the target luminance is half of the maximum luminance. For example, one pixel in the first area needs to output red, and the other pixel in the second area also outputs red, and the target gray-scale value corresponding to the pixel in the first area outputting red and having the brightness reaching half of the maximum brightness is determined by querying the first corresponding table. For example, querying the first mapping table to determine that the target grayscale value may be 128+ offset. Similarly, the target gray-scale value corresponding to the pixel of the second region outputting red and having a luminance reaching half of the maximum luminance may be 128, for example, by referring to the second correspondence table.
In operation S204, display data is output based on the target grayscale value of the first region and the target grayscale value of the second region.
For example, the pixels of the first and second regions may be controlled to output colors according to respective target gray-scale values.
According to an embodiment of the present disclosure, a transition region is further included between the first region and the second region. For example, a portion of the first region close to the second region is set as a transition region, or a portion of the second region close to the first region is set as a transition region, or a portion of the first region close to the second region and a portion of the second region close to the first region are set as transition regions.
The following description is schematically made by taking an example in which a portion of the second region close to the first region includes a transition region.
Fig. 3 schematically illustrates a schematic view in which the second region may include a transition region according to an embodiment of the present disclosure.
In the electronic device shown in fig. 3, a display screen 200 of the electronic device may include a first region 210 and a second region 220. The pixel density of the first region 210 is less than the pixel density of the second region 220.
As shown in fig. 3, the second region 220 may include a transition region 221 and a non-transition region 222.
According to an embodiment of the present disclosure, the display method may further include determining a target gray scale value of a transition region based on the target luminance value, the transition region outputting the display data based on the target gray scale value, the transition region belonging to the second region.
According to an embodiment of the present disclosure, the target gray-scale value of the transition region is controlled based on the target luminance value such that the display effect of the transition region is between the non-transition region 222 and the first region 210.
For example, the target grayscale value of the transition region may be controlled to be greater than the target grayscale value of the first region and less than the target grayscale value of the second region, where the transition region belongs to the second region.
According to the embodiment of the disclosure, the transition area is arranged between the second area and the first area, and the target gray-scale value of the transition area is controlled between the first area and the second area, so that the brightness of the first area and the second area is gradually changed, the user cannot feel suddenly changed, the brightness of the display screen looks more consistent, and the visual effect of the display screen is better.
It should be understood that in the embodiment shown in fig. 3, the transition region is disposed in the second region 220, and similarly, the transition region may be disposed in the first region 210, or both the first region 210 and the second region 220 may be disposed in the transition region.
Embodiments according to the present disclosure are described below with the transition region disposed in the second region, it being understood that the following embodiments may also be applied to embodiments in which the first region includes the transition region.
Fig. 4 schematically illustrates a schematic view of a transition region 221 according to an embodiment of the present disclosure.
As shown in fig. 4, the transition region 221 includes a plurality of first pixel circles, which may be, for example, pixel circles R1 to R4, around the first region.
According to the embodiment of the present disclosure, the target gray-scale values of the pixel circles R1 to R4 may be sequentially increased, for example.
According to an embodiment of the present disclosure, the transition region corresponds to a third pixel, and a density of the third pixel of the transition region is greater than a density of the first pixel of the first region and less than a density of the second pixel of the second region.
According to the embodiment of the disclosure, the method can reduce the difference in the display effect of the first area and the second area through a hardware technical means. The following describes a specific embodiment of this embodiment with reference to fig. 5A to 5C.
Fig. 5A schematically illustrates a schematic diagram of a pixel arrangement of a second region non-transition region according to an embodiment of the present disclosure.
Fig. 5B schematically illustrates a schematic diagram of a pixel arrangement of a second region transition region according to an embodiment of the present disclosure.
Fig. 5C schematically illustrates a schematic view of a pixel arrangement of the first region according to an embodiment of the present disclosure.
As shown in fig. 5A to 5C, the pixel density of the non-transition region of the second region is greater than the pixel density of the transition region of the second region, and the pixel density of the transition region of the second region is greater than the pixel density of the first region.
According to an embodiment of the present disclosure, the transition region may have a pixel arrangement in which pixels of the non-transition region are deleted according to a first predetermined rule, and the first region may have a pixel arrangement in which pixels of the transition region are deleted according to a second predetermined rule. As shown in fig. 5A and 5B, the pixels of the transition region may be arranged in such a manner that pixels of one row and one column in the middle of the non-transition region are removed. As shown in fig. 5B and 5C, the arrangement of the pixels of the first region may be an arrangement in which some rows of pixels and some columns of pixels are removed in the transition region.
According to the embodiment of the disclosure, the arrangement of the first pixels of the first region may be in accordance with a specific arrangement rule to ensure regular consistency of intervals formed between the pixels, so as to ensure convenience of the electronic device in performing later data optimization. For example, the first pixels may be evenly distributed in the first area.
According to an embodiment of the present disclosure, the density of the third pixels of the transition region may also be graded. For example, the density of the third pixels near the first region is less than the density of the third pixels far from the first region.
According to an embodiment of the present disclosure, in the transition region, the third pixel corresponds to the third pixel, and the density of the third pixel of the transition region is greater than the density of the first pixel of the first region and less than the density of the second pixel of the second region, the display method shown in fig. 2 may further include, on the basis of operations S201 to S204: and determining a target gray level value of the transition region based on the target brightness value, wherein the target gray level value is the gray level value obtained by accumulating the second compensation value, or determining the target gray level value of the transition region based on the target brightness value, and the target gray level value is the gray level value embodied by the third pixel corresponding to the transition region.
For example, in the scenario shown in fig. 3, a target gray level of the transition region 221 is determined according to the target brightness value, and the target gray level is a gray level obtained by accumulating the second compensation value. The target gray-scale value after accumulating the second compensation value may be between the target gray-scale value of the first area and the non-transition area of the second area. The method reduces the difference in the display effect of the first area and the second area through the combined action of hardware and software.
According to an embodiment of the disclosure, the transition region may be in the second region, for example, and the target grayscale value that is the grayscale value embodied by the third pixel corresponding to the transition region may be a grayscale value determined according to the color of the second region, the target brightness, and the second correspondence table of the target grayscale value. In other words, the target gray-scale value output by the third pixel of the transition region does not need to be compensated.
Another aspect of the present disclosure provides an electronic device. The electronic device may include a camera, a display screen, and a processor. The display area of the display screen includes a first area and a second area. The first region corresponds to the first pixel, and the second region corresponds to the second pixel. The density of the first pixels of the first region is less than the density of the second pixels of the second region. The camera sets up in the display screen below, and the collection region of camera corresponds with first region. The camera obtains ambient light through the interval between the first pixels corresponding to the first area. The processor is used for obtaining a target brightness value, determining a target gray-scale value of the first area and a target gray-scale value of the second area based on the target brightness value, and outputting display data based on the target gray-scale value of the first area and the target gray-scale value of the second area.
According to an embodiment of the present disclosure, the processor may, for example, perform operations S201-S204 described above with reference to fig. 2.
According to an embodiment of the present disclosure, the target gray-scale value of the first area is a gray-scale value obtained by accumulating a first compensation value, and the first compensation value is used to reduce a difference between the luminance of the first area and the luminance of the second area caused by a difference between the pixel density of the first area and the pixel density of the second area.
According to an embodiment of the present disclosure, a transition region is further included between the first region and the second region. The processor is further configured to determine a target gray scale value for a transition region based on the target luminance value, the transition region outputting display data based on the target gray scale value, the transition region belonging to the second region.
According to the embodiment of the present disclosure, a transition region is further included between the first region and the second region, the transition region corresponds to a third pixel, and the density of the third pixel of the transition region is greater than the density of the first pixel of the first region and less than the density of the second pixel of the second region. The processor is further configured to determine a target gray-scale value of the transition region based on the target brightness value, where the target gray-scale value is a gray-scale value obtained by accumulating the second compensation value, or determine a target gray-scale value of the transition region based on the target brightness value, where the target gray-scale value is a gray-scale value represented by a third pixel corresponding to the transition region.
