Display Brightness Adjustment via Shared Sub-pixel Identification Codes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display technologies require significant storage space for correction and identification data of pixels, which occupies excessive space and is inefficient in adjusting display brightness effectively.
Innovation Solution
A method and device that generate brightness correction and edge correction data for sub-pixels, using a mapping table to store and adjust display brightness by configuring identification data for sub-pixels based on their locations in center or edge areas, sharing codes to reduce storage needs.

Engineering Contradiction Analysis
1Manufacturing precision
If correction data and identification data of all pixels are stored separately, then brightness correction and edge correction can be precisely implemented, but storage space is excessively occupied
Solution Approach 1:
The patent merges brightness correction data and edge correction data into a unified identification data structure. Each pixel's identification data contains both brightness correction information (first code) and edge correction information (second code), eliminating the need for separate storage of correction data and reducing overall storage requirements while maintaining correction precision.
Solution Approach 2:
The identification data structure is designed to serve multiple functions simultaneously: it provides brightness correction for all pixels, edge correction for boundary pixels, and location identification. This multi-functional design eliminates redundant data storage while maintaining all necessary correction capabilities.
2Reliability
If separate correction data is stored for each pixel, then display defects can be eliminated, but the data amount occupies too much storage space
Solution Approach 1:
The patent combines multiple correction functions into a single identification data structure per pixel. The first code handles brightness correction and the second code handles edge correction, allowing both defect elimination functions to operate from unified data storage rather than requiring separate data sets.
Solution Approach 2:
The patent implements location-based data configuration where pixels in different locations (center vs. edge) have appropriately configured identification data. Center pixels receive brightness correction codes while edge pixels receive both brightness and edge correction codes, optimizing storage by providing only necessary correction data for each location.

AI summary
Provided is a method for adjusting display brightness, including: generating brightness correction data of each sub-pixel; generating edge correction data of the pixel in an edge display area; setting first codes for first sub-pixels based on the brightness correction data; setting first codes and one second code for second sub-pixels based on the brightness correction data and the edge correction data; storing a mapping table; configuring identification data of the first and second sub-pixels as first codes if the pixel is located in a center display area; configuring identification data of the first sub-pixel as a second code and identification data of the second sub-pixel as the first or second code if the pixel is located in the edge display area; storing the identification data of the first and second sub-pixels; and adjusting the display brightness of the display panel based on the mapping table and the identification data.
