Engineering Contradiction Analysis
1Manufacturing precision
If individual pixel-level voltage compensation is performed on each pixel in the display panel, then brightness uniformity is improved, but computational burden increases significantly
Solution Approach 1:
The patent segments the display panel into multiple display areas, each containing multiple pixels. Instead of processing each pixel individually, the system performs voltage compensation at the display area level. This segmentation reduces the computational complexity from O(N) where N is the total number of pixels to O(M) where M is the number of display areas, significantly reducing the computational burden while maintaining brightness uniformity through area-level compensation parameters.
Solution Approach 2:
The patent merges multiple pixels into display areas for the purpose of voltage compensation. By combining the compensation needs of multiple pixels into a single area-level compensation parameter, the system reduces the number of calculations required. The merging approach allows the system to handle high-resolution displays efficiently by treating groups of pixels as unified compensation units rather than individual processing targets.
2Manufacturing precision
If display panel resolution and size are increased, then display quality is improved, but the number of pixels increases leading to heavier computation burden
Solution Approach 1:
The patent divides the high-resolution display panel into multiple display areas, enabling the system to manage the increased number of pixels through hierarchical organization. This segmentation allows the compensation system to scale efficiently with display resolution by maintaining a manageable number of area-level parameters even as the total pixel count increases to support higher resolutions and larger display sizes.
Solution Approach 2:
The patent introduces a new dimension of organization by grouping pixels into display areas with associated compensation parameters. This dimensional change from individual pixel processing to area-level processing creates an additional hierarchical level that decouples the computational complexity from the total pixel count, enabling high-resolution displays to be managed efficiently through area-based compensation strategies.

AI summary
The present disclosure provides a voltage compensation method, a device, a terminal device and a computer readable storage medium. The method includes: obtaining pixel information and position information of a target pixel to be compensated; determining an area compensation parameter corresponding to the target pixel according to the pixel information; performing a brightness compensation on the target pixel according to the position information of the target pixel in a display panel and the area compensation parameter. The voltage compensation method determines an area compensation parameter according to the pixel information after determining the pixel information of the target pixel point, so as to obtain a target display area in a display panel. After that, a voltage compensation operation is performed on the target display area. Accordingly, the voltage compensation does not need to perform individual voltage compensation for each pixel, thereby reducing the computational burden.
