These functional entities may be implemented in the form of software, or in one or more hardware modules or integrated circuits, or in different networks and/or processor devices and/or microcontroller devices.
The exemplary embodiment first provides a Mura compensation method for a display panel, which can be applied to a terminal device. Referring to fig. 1, the method may include the steps of:
step S101: dividing a display area of the display panel into a plurality of areas; wherein the plurality of regions each include a central region and a peripheral region surrounding the central region.
Step S102: and calculating the difference value of the brightness of each peripheral area and the brightness of the corresponding central area, and obtaining the Mura compensation value of each peripheral area.
Step S103: and acquiring a preset compensation proportion value of each peripheral area, and respectively performing Mura compensation processing on each peripheral area according to the compensation proportion value corresponding to each peripheral area and the corresponding Mura compensation value.
According to the Mura compensation method of the display panel, the display area of the display panel is divided into a plurality of areas, each area comprises the central area and the peripheral area surrounding the central area, and Mura compensation is performed on the peripheral area by taking the respective central areas as reference points.
Hereinafter, the respective steps of the above-described method in the present exemplary embodiment will be described in more detail with reference to fig. 1 to 2.
In step S101, a display area of the display panel is divided into a plurality of areas; wherein the plurality of regions each include a central region and a peripheral region surrounding the central region;
for example, as shown in fig. 2, the display panel is an UHD (Ultra High Definition) display panel, and the display area is an area composed of 3840 columns of pixels and 2160 rows of pixels. The display area is divided into 9 areas on average, each area comprises a central area and a peripheral area surrounding the central area, and the central area is an area consisting of 80 columns of pixels and 80 rows of pixels, namely an 80-by-80 pixel area. It should be noted that the pixel structure of the central region may be changed according to the burn-in level of the display panel, for example, the central region may be a 12 × 12 pixel region, which is not limited herein.
In an embodiment, before the step of dividing the display area of the display panel into a plurality of areas in step S101, the method further includes:
step S1011, collecting images of the display area of the display panel under different gray scales by an optical collecting device, and averagely dividing the images into a plurality of areas.
For example, the display panel is controlled to display a specified image, such as a pure color, then the processing unit sends an instruction to an optical acquisition device, such as a CCD camera, the CCD camera captures the image of the display panel, converts the captured optical signal into a digital signal and transmits the digital signal to the processing unit, the processing unit divides the display panel into regions, and extracts and records the brightness value of the central region in each region and the brightness value of the peripheral region surrounding the central region in each region. It should be noted that the above process can be performed multiple times at different gray levels.
In step S102, a difference between each of the peripheral region luminances and its corresponding central region luminance is calculated, and a Mura compensation value for each of the peripheral regions is obtained.
For example, the obtained brightness value of the inner peripheral region of each region is compared with the brightness value of the corresponding central region, and the brightness difference between the inner peripheral region and the central region of each region is calculated, and then the Mura compensation value required to be added to each peripheral region is calculated according to the brightness difference. The detailed process can refer to the prior art and is not described herein.
In step S103, a preset compensation ratio value of each peripheral region is obtained, and Mura compensation processing is performed on the peripheral regions according to the compensation ratio value corresponding to each peripheral region and the corresponding Mura compensation value.
For example, if the preset compensation ratio value of the peripheral region in a certain region of the divided regions is a, and the Mura compensation value of a certain pixel unit in the peripheral region is X, the final Mura compensation processing data for the pixel unit is a × X, that is, a × X is the compensation data finally written into the display panel for the pixel unit.
In step S102, the Mura compensation values of the peripheral regions are calculated by the compensation value calculating means, and when the display panel displays a screen, the Mura compensation values are retrieved to compensate for the burn-in region, thereby making the screen display uniform.
The specific optimization method for each region is that, after the peripheral regions are subjected to Mura compensation, the brightness values in the peripheral regions are all consistent with the brightness values of the corresponding central regions, and in step S1011, the CCD camera feeds back the brightness values of the central regions in each region to a processing unit, and the processing unit performs calculation, so that the central regions in each region tend to be uniform, that is, the whole regions tend to be uniform. Meanwhile, the brightness value of the boundary line position between the regions is detected, and the boundary position is compensated by referring to the central brightness values of the upper, lower, left and right side regions. The preset compensation proportion value suitable for each peripheral area can be generated through calculation of the processing unit, when a display panel displays a picture, the preset compensation proportion value of each peripheral area can be obtained, and then Mura compensation processing is respectively carried out on each peripheral area according to the compensation proportion value corresponding to each peripheral area and the corresponding Mura compensation value. Meanwhile, the central area in each area is also compensated for brightness according to the compensation value calculated by the processing unit, so that the entire display screen of the display panel is displayed uniformly.
In an embodiment, the method further includes performing an update adjustment process on the preset compensation value of each peripheral region.
For example, the branding area and the branding degree of each display panel are different, and when the pixel composition of the central area in each area is changed and the number of areas of the divided areas of the display panel is changed, the preset compensation value of each peripheral area is affected, so that the preset compensation value of each peripheral area needs to be updated and adjusted according to different situations.
In an embodiment, the predetermined compensation ratio values corresponding to the peripheral regions are the same or not completely the same.
For example, if the branding area of the display panel is uniform, after the display panel is divided into a plurality of areas, the preset compensation proportion value corresponding to each peripheral area is also the same; however, most of the display panels have different branding areas and levels, i.e., the preset compensation ratios for the peripheral areas are not completely the same.
In an embodiment, the preset compensation ratio value and the corresponding Mura compensation value corresponding to each peripheral region are stored in the display panel.
For example, when the Mura compensation value is collocated with a preset compensation ratio value of a corresponding region, the compensation effect on the display panel can be good, and the display region of the display panel is enabled to be transited uniformly. And then storing the preset compensation proportion value and the corresponding Mura compensation value corresponding to each peripheral area into the display panel, and calling the compensation values at any time when the display panel displays pictures.
According to the Mura compensation method for the display panel, the display area of the display panel is divided into a plurality of areas, each area comprises the central area and the peripheral area surrounding the central area, and Mura compensation is performed on the peripheral area by taking the respective central areas as reference points.
It should be noted that although the various steps of the methods of the present disclosure are depicted in the drawings in a particular order, this does not require or imply that these steps must be performed in this particular order, or that all of the depicted steps must be performed, to achieve desirable results. Additionally or alternatively, certain steps may be omitted, multiple steps combined into one step execution, and/or one step broken down into multiple step executions, etc. Additionally, it will also be readily appreciated that the steps may be performed synchronously or asynchronously, e.g., among multiple modules/processes/threads.

And the adjusting unit is used for updating and adjusting the preset compensation proportion value of each peripheral area.
