Display Panel Boundary Definition via Slope-Adaptive Pixel Arrangement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In display devices with both high-resolution and low-resolution areas, the boundary between these regions is visually recognizable due to definition deterioration caused by luminance differences, leading to a decrease in overall image quality.
Innovation Solution
A display device design that includes a low-resolution area with a polygonal shape overlapping an optical module, where unit pixels and transmission areas are arranged differently based on the slope of the boundary with the high-resolution area, combined with a timing controller that applies color weights to compensate for luminance differences, converting 3-color data to 4-color data and back to 3-color data to enhance the low-resolution area's definition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If a low-resolution area is created by reducing pixel density to secure light transmissivity for the optical module, then light transmissivity is improved, but definition deterioration occurs in the low-resolution area
Solution Approach 1:
The patent applies local quality by creating different pixel arrangements in different regions: the low-resolution area has a first pixel arrangement with lower density for light transmissivity, while the boundary area has a second pixel arrangement with higher density and different patterns to improve definition. This localized differentiation resolves the contradiction between light transmissivity and definition.
Solution Approach 2:
The display area is segmented into multiple regions with different pixel arrangements: the low-resolution area superposed on the optical module, the boundary area surrounding it, and the high-resolution area. Each segment has optimized pixel density and arrangement patterns to balance light transmissivity and definition requirements.
2Use of energy by moving object
If unit pixels are arranged in lower pixel density in the low-resolution area, then light transmissivity is secured, but visual recognition of the boundary area becomes problematic
Solution Approach 1:
The patent implements local quality by designing specific pixel arrangements for the boundary area that differ from both the low-resolution and high-resolution areas. The boundary area uses intermediate pixel density and specific patterns (including transmission areas and dummy pixels) to smoothly transition between regions, preventing visual recognition of boundaries while maintaining light transmissivity.
Solution Approach 2:
The patent addresses boundary visual recognition by introducing dimensional variations in pixel arrangement patterns. Different boundary areas (first, second, third, fourth boundary areas) use different pixel arrangements oriented in different directions, creating a multi-dimensional transition that reduces visible boundaries.
3Use of energy by moving object
If the display area is divided into high-resolution and low-resolution areas, then light transmissivity for the optical module is improved, but the boundary area between these regions becomes visually recognizable
Solution Approach 1:
The patent segments the display area into distinct zones with different pixel arrangements: low-resolution area, multiple boundary areas (first through fourth), and high-resolution area. Each segment has optimized characteristics that collectively create a smooth visual transition, reducing the visibility of boundaries while maintaining the low-resolution area for optical module light transmissivity.
Solution Approach 2:
The patent applies asymmetry by using different pixel arrangements for different boundary areas surrounding the low-resolution area. Each boundary area has a unique pattern asymmetrically designed to match its position and orientation, preventing uniform visual recognition of boundaries while optimizing light transmissivity in the low-resolution area.
