Display Device With Overlapping Compensation Electrode and Wiring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display panels with atypical shapes face challenges in maintaining uniform luminance and image quality due to variations in display area dimensions and pixel arrangements, leading to inconsistencies in image display.
Innovation Solution
The design includes a base layer with defined display and non-display areas, featuring multiple display areas with varying protrusions, compensation electrodes, and compensation wiring that overlap in a plan view, ensuring uniform luminance by adjusting the number and arrangement of pixels and compensation patterns to match different display areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the display area has an atypical shape with protrusions, then the display device can achieve unique design and larger display area, but the luminance becomes non-uniform across different areas
Solution Approach 1:
The patent applies local quality by configuring different numbers of compensation patterns in different display areas. Specifically, the first display area has a first number of compensation patterns while the second display area has a second number of compensation patterns, allowing each area to be optimized for its specific geometric characteristics and pixel arrangement, thereby achieving uniform luminance across the entire atypical display area.
2Illumination intensity
If the number of pixels is adjusted to match different display areas, then the luminance uniformity is improved, but the device complexity increases
Solution Approach 1:
The patent implements local quality by adjusting the number of pixels and compensation patterns according to the specific requirements of different display areas. The first display area contains a first number of pixels with a first number of compensation patterns, while the second display area contains a second number of pixels with a second number of compensation patterns, optimizing each area independently to achieve uniform luminance while managing complexity.
3Illumination intensity
If compensation patterns are added to uniform luminance, then the luminance uniformity is improved, but the response speed difference between areas increases
Solution Approach 1:
The patent addresses this contradiction by locally optimizing the number of compensation patterns in each display area. The first display area has a first number of compensation patterns and the second display area has a second number of compensation patterns, allowing each area to achieve both uniform luminance and acceptable response speed according to its specific geometric and pixel arrangement characteristics.
