Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing organic light-emitting display panels face challenges in improving resolution without increasing technology complexity or manufacturing processes.
Innovation Solution
The design includes sub-pixel units defined by a bank, with multiple sub-pixels of the same color, each with independent first electrodes, and pixel circuits arranged in a rectangular array to control sub-pixels in a non-rectangular array, allowing for high-resolution display modes and efficient wire layout.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple sub-pixels with independent first electrodes are arranged in a non-rectangular array within sub-pixel units, then resolution is improved, but wire layout complexity increases
Solution Approach 1:
The display panel is divided into multiple sub-pixel units, each containing multiple sub-pixels with independent first electrodes. This segmentation allows each sub-pixel to be independently controlled by its own pixel circuit, enabling high-resolution display while maintaining manageable wire layout through modular organization
Solution Approach 2:
The patent transitions from traditional rectangular array arrangement to a non-rectangular array arrangement of sub-pixels within sub-pixel units. This dimensional reorganization optimizes the spatial distribution of sub-pixels, improving resolution by enabling more efficient use of the display area while the modular sub-pixel unit structure keeps wire layout complexity controlled
2Ease of manufacture
If pixel circuits are arranged in a rectangular array to control non-rectangular sub-pixel arrays, then manufacturing ease is improved, but adaptability to different display modes is reduced
Solution Approach 1:
The display is segmented into multiple sub-pixel units that can be independently configured. Each sub-pixel unit contains multiple sub-pixels that can be selectively activated, allowing the same rectangular pixel circuit array to support various display modes (full resolution, half resolution, quarter resolution) by controlling different combinations of sub-pixels
Solution Approach 2:
The patent implements dynamic display mode switching capability where the same physical structure can operate in different resolution modes. By dynamically controlling which sub-pixels within each sub-pixel unit are activated, the system adapts between full resolution mode (all sub-pixels on) and lower resolution modes (selective sub-pixel activation), providing versatility without changing the manufacturing structure
