Display Panel Pixel Circuit Transition for Uniform Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices experience significant differences between various display areas, leading to sudden changes in the viewing experience due to varying numbers of pixel circuits driving light-emitting elements, which affects the overall user experience, especially in low-gray-scale panels.
Innovation Solution
A display panel design that includes a transition display area with a specific arrangement of sub-display areas, where the number of pixel circuits for each light-emitting element in the transition area is between that of the first and second sub-display areas, smoothing the transition between different display effects to reduce visual differences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different display areas use different numbers of pixel circuits per light-emitting element, then display flexibility and functional integration are improved, but display consistency and viewing experience deteriorate
Solution Approach 1:
The patent applies local quality by creating different pixel circuit configurations in different display areas. The first display area uses a first pixel circuit structure, the second display area uses a second pixel circuit structure, and the transition display area uses a third pixel circuit structure that combines elements of both. This allows each area to have optimized local characteristics while maintaining overall display consistency through the transition area that gradually changes the pixel circuit configuration.
Solution Approach 2:
The transition display area acts as an intermediary between the first and second display areas. It contains a gradient of pixel circuit configurations that smoothly transition from the first type to the second type, preventing abrupt changes in display characteristics. This intermediary zone with intermediate pixel circuit structures bridges the gap between different display areas, ensuring visual continuity.
2Manufacturing precision
If a transition display area with intermediate pixel circuit configurations is introduced, then display consistency is improved, but device complexity increases
Solution Approach 1:
The display panel is segmented into three distinct display areas: first display area, transition display area, and second display area. Each area has its own characteristic pixel circuit configuration. This segmentation allows the complex transition from one pixel circuit type to another to be divided into manageable zones, with the transition area containing intermediate configurations that bridge the gap between the two main display areas.
Solution Approach 2:
The patent changes the parameters of pixel circuits gradually across the transition display area. The pixel circuits in the transition area have configurations that are intermediate between the first and second display areas, creating a gradient transition. This parameter change approach allows smooth visual transition while managing complexity by systematically varying circuit characteristics rather than introducing entirely new structures.

AI summary
A display panel includes a first display area, a second display area, and a transition display area there-between. The first display area includes a plurality of first sub-display areas, the second display area includes a plurality of second sub-display areas, and the transition display area includes at least one sub-transition area. A first sub-display area of the plurality of first sub-display areas, a second sub-display area of the plurality of second sub-display areas and a sub-transition area include a same number of light-emitting elements. Number of pixel circuits for driving each light-emitting element in one of the at least one sub-transition area is greater than number of pixel circuits for driving each light-emitting element in one of the plurality of first sub-display areas and is smaller than number of pixel circuits for driving each light-emitting element in one of the plurality of second sub-display areas.
