Irregular Sub-pixel Arrangement for Display Diffraction Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Full-screen display panels struggle to achieve both a better display effect and a better shooting effect in the imaging region due to the conflicting requirements of high pixel density and weak diffraction effect, as regularly arranged non-light-transmitting sub-pixels enhance display but worsen imaging, while lower pixel density improves imaging but compromises display quality.
Innovation Solution
A display panel design featuring a first display region with both light-transmitting and non-light-transmitting sub-pixels arranged in a preset pixel structure, where non-light-transmitting sub-pixels are randomly and irregularly arranged to reduce diffraction effects, allowing for high pixel density and improved display and shooting performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If non-light-transmitting sub-pixels are regularly arranged to enhance display effect, then pixel density is increased, but diffraction effect is strengthened and shooting effect deteriorates
Solution Approach 1:
The patent applies asymmetry by transitioning from regular to irregular arrangement of non-light-transmitting sub-pixels. The irregular arrangement breaks the periodic structure that causes diffraction, thereby reducing the diffraction effect while maintaining high pixel density. This asymmetric distribution prevents the formation of regular diffraction patterns.
Solution Approach 2:
The patent implements local quality by differentiating the arrangement characteristics of non-light-transmitting sub-pixels in different regions. By making the arrangement locally irregular rather than globally regular, the patent reduces diffraction effects in the imaging region while preserving display quality in other areas.
2Object-generated harmful factors
If pixel density is reduced to weaken diffraction effect, then shooting effect is improved, but display effect deteriorates
Solution Approach 1:
The patent uses asymmetric irregular arrangement to achieve a win-win situation: high pixel density is maintained for display quality, while the irregular pattern itself reduces diffraction effects. This eliminates the need to reduce pixel density to improve shooting effect.
3Area of stationary object
If full-screen display is implemented to maximize display area, then display effect is improved, but imaging region quality deteriorates due to regular pattern diffraction
Solution Approach 1:
The patent applies asymmetry specifically in the imaging region by irregularly arranging non-light-transmitting sub-pixels, while maintaining regular or optimized arrangements in other display regions. This allows full-screen display area to be maximized while preventing diffraction effects in the critical imaging area.

AI summary
A display panel includes a first display region with multiple light-transmitting sub-pixels and multiple non-light-transmitting sub-pixels. The multiple light-transmitting sub-pixels and the multiple non-light-transmitting sub-pixels are arranged in a preset pixel arrangement structure in the first display region. The multiple non-light-transmitting sub-pixels are randomly arranged in at least one set region of the first display region.
