[0002] With the development of display technologies, full-screen display panels have received extensive attention because they have a large screen-to-body ratio and ultra-narrow borders, which can greatly improve the visual effect of viewers compared with ordinary display panels.

[0042] The present invention will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present invention, rather than limiting the present invention. Additionally, it should be noted that for the sake of description, only parts related to the present invention are shown in the drawings, not all structures.

[0043] As mentioned in the background art, when the existing display panel is designed, there are prone to problems such as unnatural transitions between the secondary screen area and the main screen area, resulting in poor display effects of the display panel. After research, the inventor found that the reason for this problem is that when the existing display panel is designed and completed, usually only the gray-scale images of the display panel are simulated. When the display effect of the gray-scale images meets the requirements, the display panel will be put into production. Then, during the use of the display panel, most of the time it displays images with colors, texts, lines, etc., resulting in display deviations still existing during the display process of the produced display panel, affecting the display effect.

[0044] Based on the above problems, the following solutions are proposed in this embodiment:

[0045] Figure 1 It is a schematic flowchart of a display simulation method for a display panel provided by an embodiment of the present invention. Figure 2 It is a schematic diagram of a display panel provided by an embodiment of the present invention. Referring to Figure 1 and Figure 2 , this embodiment provides a display simulation method for a display panel. The display panel includes a main screen area 1 and a secondary screen area 2 adjacent to the main screen area 1. The sub-pixel density of the main screen area 1 is greater than that of the secondary screen area 2. The display simulation method of the display panel includes:

[0046] Step 110, obtain any non-solid-color image; wherein, the resolution of the non-solid-color image is the same as that of the display panel.

[0047] Specifically, the secondary screen area of the display panel is a transparent display area, corresponding to the area where optical sensors such as cameras are set. Through the secondary screen area, the optical sensors such as cameras can achieve the photosensitive function. Among them, the sub-pixel density of the secondary screen area is less than that of the main screen area, ensuring that more light can pass through the secondary screen area and ensuring the normal operation of the optical sensors such as cameras. The non-solid-color image is an image with inconsistent colors throughout the whole picture, such as an image with texts, lines or colors. Exemplary non-solid-color images can be color images, images with texts or maps, etc. The resolution of the non-solid-color image is the same as that of the display panel, ensuring that each sub-pixel of the display panel has a corresponding pixel point in the non-solid-color image.

[0048] Step 120, determine the display sub-pixels in the non-solid-color image corresponding to each sub-pixel of the display panel according to the position coordinates of each sub-pixel of the display panel, and set the sub-pixels other than the display sub-pixels in the non-solid-color image to the off state.

[0049] Specifically, a non-solid-color image includes multiple pixel points, and a display sub-pixel is a pixel point in the non-solid-color image corresponding to a sub-pixel on the display panel. By setting the sub-pixels other than the display sub-pixels in the non-solid-color image to the off state, all the lit pixel points in the adjusted non-solid-color image correspond to the sub-pixels on the display panel.

[0050] Step 130: Adjust the current display brightness of the display sub-pixels in the non-solid-color image corresponding to the main screen area of the display panel to a preset brightness, where the ratio of the current display brightness to the preset brightness is a preset ratio, and the preset ratio is determined according to the ratio of the sub-pixel density of the main screen area to the sub-pixel density of the secondary screen area.

[0051] Specifically, since the sub-pixel density of the main screen area is greater than that of the secondary screen area, to ensure the display consistency of the display panel, it is usually necessary to adjust the brightness of the sub-pixels in the main screen area or the secondary screen area. For example, at the same display gray level, among the sub-pixels of the same color, the brightness of the sub-pixels in the main screen area is less than that of the sub-pixels in the secondary screen area. By adjusting the brightness of the display sub-pixels corresponding to the main screen area to the preset brightness, such as by reducing the brightness of the display sub-pixels corresponding to the main screen area, the display effect of the non-solid-color image conforms to the actual display effect of the display panel. Exemplarily, when the sub-pixel density of the main screen area is twice that of the secondary screen area, the preset ratio is 4, and the brightness of the display sub-pixels in the main screen area is adjusted to one-fourth of the current display brightness.

[0052] The display simulation method for a display panel provided by an embodiment of the present invention includes obtaining a non-solid-color image with any resolution the same as that of the display panel; determining the display sub-pixels in the non-solid-color image corresponding to the sub-pixels of the display panel according to the position coordinates of the sub-pixels of the display panel, and setting the sub-pixels other than the display sub-pixels in the non-solid-color image to the off state; and adjusting the current display brightness of the display sub-pixels in the non-solid-color image corresponding to the main screen area of the display panel to a preset brightness, where the ratio of the current display brightness to the preset brightness is a preset ratio, and the preset ratio is determined according to the ratio of the sub-pixel density of the main screen area to the sub-pixel density of the secondary screen area. The display simulation method for the display panel provided by this embodiment uses an existing non-solid-color image. By turning off the pixel points in the non-solid-color image that do not correspond to the sub-pixels of the display panel, all the lit pixel points in the adjusted non-solid-color image correspond to the sub-pixels on the display panel, and by adjusting the display brightness of the display sub-pixels corresponding to the main screen area in the non-solid-color image, the adjusted non-solid-color image conforms to the actual display effect of the display panel. The simulation method provided by this embodiment does not require designing a complex calculation program. Only by adjusting an existing arbitrary non-solid-color image can the simulation of the display effect of any color picture on the display panel with a secondary screen area be realized, so that the design of the display panel can be adjusted according to the simulation, making the actual display effect of the display panel better.

[0053] Optionally, adjusting the current display brightness of the display sub-pixels corresponding to the main screen area of the display panel to a preset brightness includes adjusting the current display gray level of the display sub-pixels corresponding to the main screen area of the display panel to a preset gray level.

[0054] Among them, the preset gray level can be determined according to the current display gray level of the display sub-pixels, the sub-pixel density of the main screen area, the sub-pixel density of the secondary screen area, and the gamma value. Exemplarily, the current brightness of the display sub-pixels can be determined according to their current display gray level, the ratio of the sub-pixel density of the main screen area to the sub-pixel density of the secondary screen area can be used to determine the brightness ratio of the sub-pixels in the main screen area to the sub-pixels in the secondary screen area under the same display gray level, the brightness reduction degree of the sub-pixels in the main screen area can be determined according to this brightness ratio, and the preset gray level of the display sub-pixels corresponding to the main screen area in the non-solid color image can be determined according to the reduced brightness and the gamma value. Among them, the gamma value can be 2.1 or 2.2, etc. The specific value of the gamma value can be determined according to the display requirements of the display panel, and this embodiment does not make specific limitations. In this embodiment, the gray level of the display sub-pixels corresponding to the main screen area in the non-solid color image is adjusted through the current display gray level of the display sub-pixels, the sub-pixel density of the main screen area, the sub-pixel density of the secondary screen area, and the gamma value, so that the adjusted non-solid color image conforms to the actual display effect of the display panel, and thus the design of the display panel can be adjusted according to the adjusted non-solid color image, making the actual display effect of the display panel better.

[0055] Optionally, the following formula is used to determine the preset gray level n:

[0056] L N =(N / 255) 2.2 *L max ;

[0057] n=(L N / p / L max ) 1 / 2.2 *255;

[0058] Among them, L N is the current display brightness corresponding to the current display gray level N of the display sub-pixels, p is the square of the ratio of the sub-pixel density of the main screen area to the sub-pixel density of the secondary screen area, and L max is the brightness corresponding to 255 gray levels.

[0059] Specifically, first calculate the current display brightness L max of the display sub-pixels according to the maximum display brightness L N of the display panel, the current display gray level N of the display sub-pixels, and the gamma formula. To ensure the display consistency of the display panel, the brightness of the display sub-pixels corresponding to the main screen area is adjusted to L N / p, and calculate L NThe gray level corresponding to / p, that is, the preset gray level n. Exemplarily, the sub-pixel density of the main screen area is 400 PPI, and the sub-pixel density of the secondary screen area is 200 PPI. To ensure that the brightness per unit area of the main screen area is the same as that of the secondary screen area under the same display gray level, the brightness of the sub-pixels in the main screen area needs to be adjusted to one-fourth of the original. The gamma value in this embodiment is set to 2.2. In practical applications, the gamma value can be adjusted according to actual situations.

[0060] In this embodiment, the display gray level of the sub-pixels in the main screen area is adjusted according to the gamma formula to ensure that the display effect of the main screen area after adjustment conforms to the gamma curve and meets the actual display requirements of the display panel.

[0061] Optionally, determining the display sub-pixels corresponding to the sub-pixels of the display panel in the non-solid-color image according to the position coordinates of the sub-pixels of the display panel includes: obtaining a gray-level simulation diagram of the display panel; wherein, the display gray levels of the sub-pixels of the display panel in the gray-level simulation diagram are the same and not 0; and determining the sub-pixels in the non-solid-color image corresponding to the sub-pixels in the gray-level simulation diagram as the display sub-pixels.

[0062] Specifically, the non-solid-color image can be directly compared with the gray-level simulation diagram, and the pixel points at the corresponding positions in the non-solid-color image and the gray-level simulation diagram are determined as the display sub-pixels. Only by comparing the two pictures, the process of determining the display sub-pixels is relatively simple, which improves the simulation speed.

[0063] Optionally, the non-solid-color image includes a color image, an image with text, or a map.

[0064] Specifically, since the display screens in reality are usually non-solid-color images, this embodiment uses non-solid-color images for the display simulation of the display panel, which can intuitively determine the display effect of the display panel on non-solid-color images and facilitate the adjustment of the design of the display panel. The non-solid-color image can be a color image, an image with text, or a map. Figure 3 It is a schematic diagram of the simulation result of a display simulation method for a display panel provided by an embodiment of the present invention. Refer to Figure 3 , area 210 is the secondary screen area, and the remaining areas are the main screen areas.

[0065] Optionally, after adjusting the current display gray level of the display sub-pixels corresponding to the main screen area of the display panel to the preset gray level, it further includes:

[0066] Adjusting the display gray level of the display sub-pixels on the set boundary in the non-solid-color image, where the set boundary corresponds to the boundary of the main screen area adjacent to the secondary screen area.

[0067] Specifically, due to the different sub-pixel densities of the main screen area and the secondary screen area, the emission brightness is different under the same display gray level. Therefore, bright edges, dark edges, color deviation, etc. are likely to occur at the junction between the main screen area and the secondary screen area. The display gray level of some display sub-pixels on the set boundary in the non-solid color image can be increased or decreased to compensate for bright edges, dark edges, color deviation, etc. Thus, according to the simulation results, the driving data of the corresponding sub-pixels in the display panel can be adjusted. The simulation scheme provided in this embodiment simulates the compensation effect of the display panel by adjusting the display gray level of the display sub-pixels on the set boundary in the simulation image. According to the simulation results, the driving data of some sub-pixels in the display panel can be adjusted to improve the display effect of the display panel.

[0068] Optionally, after adjusting the gray level of the display sub-pixels corresponding to the main screen area of the display panel in the non-solid color image to a preset gray level, it further includes:

[0069] Setting the set sub-pixels other than the display sub-pixels in the non-solid color image to the on state, where the set sub-pixels include some sub-pixels in the area between the main screen area and the secondary screen area.

[0070] Specifically, by setting the set sub-pixels in the non-solid color image to the on state, compensation for bright edges, dark edges, color deviation, etc. is achieved. Thus, according to the simulation results, the pixel arrangement of the display panel can be adjusted. The simulation scheme provided in this embodiment simulates the compensation effect of the display panel by turning on some sub-pixels other than the display sub-pixels in the simulation image. According to the simulation results, sub-pixels at the corresponding positions can be added in the display panel to improve the display effect of the display panel.

[0071] An embodiment of the present invention further provides a display simulation device for a display panel. The display panel includes a main screen area and a secondary screen area adjacent to the main screen area, and the sub-pixel density of the main screen area is greater than that of the secondary screen area;

[0075] The grayscale adjustment module 330 is configured to adjust the current display brightness of the display sub-pixels corresponding to the main screen area of the display panel in the non-solid-color image to a preset brightness, wherein the ratio of the current display brightness to the preset brightness is a preset ratio, and the preset ratio is determined according to the ratio of the sub-pixel density of the main screen area to the sub-pixel density of the secondary screen area.

[0076] In this embodiment, an existing non-solid-color image is used.

[0078] The preset grayscale n is determined by the following formula:
