Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
As mentioned in the background art, the conventional display panel is prone to have a problem of unnatural transition between the secondary screen area and the primary screen area during design, which results in a poor display effect of the display panel. Then, the display panel displays images with colors, characters, lines and the like in most of time in the using process, so that display deviation still exists in the display process of the produced display panel, and the display effect is influenced.
Based on the above problem, the present embodiment proposes the following solutions:
fig. 1 is a schematic flowchart of a display simulation method of a display panel according to an embodiment of the present invention, and fig. 2 is a schematic diagram of a display panel according to an embodiment of the present invention. Referring to fig. 1 and fig. 2, the present embodiment provides a display simulation method for a display panel, where the display panel includes a main screen area 1 and a sub-screen area 2 adjacent to the main screen area 1, and a sub-pixel density of the main screen area 1 is greater than a sub-pixel density of the sub-screen area 2. The display simulation method of the display panel comprises the following steps:
step 110, acquiring any non-pure color image; wherein the resolution of the non-solid image is the same as the resolution of the display panel.
Specifically, the sub-screen area of the display panel is a transparent display area, and corresponds to an area where optical sensors such as a camera are arranged, and the optical sensors such as the camera can realize a photosensitive function by penetrating through the sub-screen area. The sub-pixel density of the auxiliary screen area is smaller than that of the main screen area, so that more light can penetrate through the auxiliary screen area, and normal work of optical sensors such as a camera is guaranteed. The non-solid image is an image with inconsistent display colors, such as an image with characters, lines or colors, and an exemplary non-solid image can be a color image, an image with characters, a map or the like. The resolution ratio of the non-pure color image is the same as that of the display panel, and the sub-pixels of the display panel are guaranteed to have corresponding pixel points in the non-pure color image.
And step 120, determining display sub-pixels corresponding to the sub-pixels of the display panel in the non-pure color image according to the position coordinates of the sub-pixels of the display panel, and setting the sub-pixels except the display sub-pixels in the non-pure color image to be in an off state.
Specifically, the non-solid color image includes a plurality of pixel points, and the display sub-pixels are pixel points corresponding to the sub-pixels on the display panel in the non-solid color image. And setting the sub-pixels except the display sub-pixels in the non-pure color image to be in a closed state, so that all lightened pixel points in the adjusted non-pure color image correspond to the sub-pixels in the display panel.
Step 130, adjusting the current display brightness of the display sub-pixels corresponding to the main screen area of the display panel in the non-pure color image to be 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 auxiliary screen area.
Specifically, since the sub-pixel density of the main screen area is greater than that of the sub-screen area, in order to ensure the display consistency of the display panel, the brightness of the sub-pixels of the main screen area or the sub-screen area is usually required to be adjusted. For example, in the sub-pixels with the same color and the same display gray scale, the sub-pixel brightness of the main screen area is smaller than that of the sub-pixel brightness of the sub-screen area. The brightness of the display sub-pixels corresponding to the main screen area is adjusted to be preset brightness, for example, the brightness of the display sub-pixels corresponding to the main screen area is reduced, so that the display effect of the non-pure-color image accords with the actual display effect of the display panel. For example, when the sub-pixel density of the main screen area is 2 times that of the sub-screen area, and the preset ratio is 4, the brightness of the sub-pixels displayed in the main screen area is adjusted to be one fourth of the current display brightness.
The display simulation method of the display panel provided by the embodiment of the invention comprises the steps of obtaining any non-pure color image with the resolution same as that of the display panel; determining display sub-pixels corresponding to the sub-pixels of the display panel in the non-pure color image according to the position coordinates of the sub-pixels of the display panel, and setting the sub-pixels except the display sub-pixels in the non-pure color image to be in an off state; and adjusting the current display brightness of the display sub-pixels corresponding to the main screen area of the display panel in the non-pure-color image to be 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 auxiliary screen area. The display simulation method for the display panel provided by this embodiment adopts the existing non-solid color image, and closes the pixel points in the non-solid color image that do not correspond to the sub-pixels of the display panel, so that all the lighted pixel points in the adjusted non-solid color image correspond to the sub-pixels in the display panel, and the adjusted non-solid color image conforms to the actual display effect of the display panel by adjusting the display brightness of the display sub-pixels in the non-solid color image that are opposite to the main screen area. According to the simulation method provided by the embodiment, a complex calculation program is not needed to be designed, and the simulation of the display effect of the display panel with the auxiliary screen area on any color picture can be realized only by adjusting any existing non-pure color picture, so that the design of the display panel can be adjusted according to the simulation, and the actual display effect of the display panel is better.

The preset gray scale can be determined according to the current display gray scale of the display sub-pixels, the sub-pixel density of the main screen area, the sub-pixel density of the auxiliary screen area and the gamma value, for example, the current brightness of the display sub-pixels can be determined according to the current display gray scale of the display sub-pixels, the brightness ratio of the sub-pixels of the main screen area to the sub-pixels of the auxiliary screen area under the same display gray scale is determined according to the ratio of the sub-pixel density of the main screen area to the sub-pixel density of the auxiliary screen area, the brightness reduction degree of the sub-pixels of the main screen area is determined according to the brightness ratio, and the preset gray scale of the display sub-pixels corresponding to the main screen area in the non-solid-color image is determined according to the reduced brightness and the gamma value. The gamma value may be 2.1 or 2.2, and the specific value of the gamma value may be determined according to the display requirement of the display panel, which is not specifically limited in this embodiment. In the embodiment, the gray scale of the display sub-pixel corresponding to the main screen area in the non-solid color image is adjusted through the current display gray scale of the display sub-pixel, the sub-pixel density of the main screen area, the sub-pixel density of the sub-screen area and the gamma value, so that the adjusted non-solid color image accords with the actual display effect of the display panel, the design of the display panel can be adjusted according to the adjusted non-solid color image, and the actual display effect of the display panel is better.
Optionally, the preset gray level n is determined by the following formula:
LN＝(N/255)2.2*Lmax；
n＝(LN/p/Lmax)1/2.2*255；
wherein L isNP is the square of the ratio of the sub-pixel density of the main screen area to the sub-pixel density of the sub-screen area, LmaxThe brightness corresponds to 255 gray levels.
Specifically, first, the maximum display brightness L of the display panel is determinedmaxCalculating the current display brightness L of the display sub-pixel by the current display gray scale N of the display sub-pixel and a gamma formulaN. In order to ensure the display consistency of the display panel, the brightness of the display sub-pixel corresponding to the main screen area is adjusted to be LNP, calculating L according to the gamma formulaNThe gray scale corresponding to/p is the preset gray scale n. For example, the sub-pixel density of the main screen area is 400PPI, the sub-pixel density of the auxiliary screen area is 200PPI, and in order to ensure that the brightness of the main screen area per unit area and the brightness of the auxiliary screen area per unit area are the same under the same display gray scaleThe brightness is the same, and the brightness of the sub-pixels in the main screen area needs to be adjusted to be one fourth of the original brightness. The gamma value in this embodiment is set to 2.2, and in practical application, the gamma value can be adjusted according to actual conditions.
According to the embodiment, the display gray scale of the sub-pixels in the main screen area is adjusted according to the gamma formula, so that the display effect of the adjusted main screen area is ensured to accord with a gamma curve and the actual display requirement of the display panel.
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: acquiring a gray scale simulation diagram of a display panel; the display gray scales of the sub-pixels of the display panel in the gray scale simulation graph are the same and are not 0; and determining the sub-pixels corresponding to the sub-pixels in the gray-scale simulation image in the non-pure-color image as display sub-pixels.
