Display Panel Data Compensation for Viewing Angle and Image Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display technologies face challenges in maintaining image quality when switching between different viewing angle improvement rates, leading to incorrect gray-scale generation and deterioration of display image quality.
Innovation Solution
A method for compensating display data of a display panel involves obtaining display data, determining a viewing angle improvement rate, obtaining a target compensation table based on this rate, and compensating the display data using this table. This approach allows for different target compensation tables to be used based on varying viewing angle improvement rates, preventing incorrect gray-scale generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the viewing angle improvement algorithm is enabled to improve viewing angle characteristics, then viewing angle performance is improved, but image quality deteriorates due to graininess
Solution Approach 1:
The patent applies dynamics by making the viewing angle improvement rate adjustable and image-dependent rather than fixed. The system dynamically selects different viewing angle improvement rates (0%, 50%, 100%) based on image characteristics and viewing conditions, allowing optimal balance between viewing angle performance and image quality for different scenarios
Solution Approach 2:
The patent changes the parameter of gray-scale values through compensation algorithms. By adjusting gray-scale parameters based on the selected viewing angle improvement rate and image characteristics, the system compensates for the graininess effect while maintaining improved viewing angle characteristics, thus resolving the contradiction between the two performance aspects
2Manufacturing precision
If the viewing angle improvement rate is changed to optimize for different images, then image quality can be improved, but debugging effect deteriorates due to incorrect gray-scales
Solution Approach 1:
The patent applies preliminary action by pre-establishing multiple compensation algorithms corresponding to different viewing angle improvement rates (0%, 50%, 100%). When the viewing angle improvement rate is changed, the system automatically selects the corresponding pre-configured compensation algorithm, ensuring correct gray-scales are generated without requiring re-debugging. This preliminary preparation of multiple compensation strategies eliminates the need for manual re-adjustment when switching between different viewing angle improvement rates
3Device complexity
If a single compensation algorithm is used for all viewing angle improvement rates, then device complexity is reduced, but image quality deteriorates when switching rates
Solution Approach 1:
The patent applies universality by designing a multi-functional compensation system where a single compensation module can handle multiple viewing angle improvement rates (0%, 50%, 100%) through different compensation algorithms. The system universally applies the appropriate compensation strategy based on the current viewing angle improvement rate, maintaining image quality across all operating conditions without requiring separate hardware paths for each rate

AI summary
A method of compensating for data of a display panel includes: obtaining display data of an image to be displayed; determining a viewing angle improvement rate for improving viewing angle of the display panel based on the display data; obtaining a target compensation table for compensating the display panel by a preset compensation algorithm based on the viewing angle improvement rate; and compensating for the display data based on the target compensation table.
