Dummy Pixel Color Arrangement for Display Boundary Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Reducing the bezel size of display devices to increase the screen-to-body ratio poses challenges in integrating optical devices within the screen, leading to display quality deterioration due to color shift and interference at the boundaries between pixel areas.
Innovation Solution
The integration of dummy pixels with varying light emission colors and arrangements at the edges of the second pixel area, surrounded by a first pixel area, to minimize interference and maintain display quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the bezel size is reduced to increase screen-to-body ratio, then the screen-to-body ratio is improved, but it becomes difficult to dispose the optical device to the bezel region
Solution Approach 1:
The optical device is nested within the screen area by creating a transparent region that allows light to pass through to the optical device. The pixel arrangement is designed so that pixels in the transparent region have different arrangements than pixels in the display region, enabling the optical device to be integrated within the screen boundaries while maintaining display functionality.
2Ease of operation
If the optical device is disposed within the screen, then the ease of disposing optical device is improved, but display quality deteriorates due to color shift at the boundary of regions with different pixel arrangement
Solution Approach 1:
Different pixel arrangements are applied to different regions: pixels in the display region follow one arrangement pattern, while pixels in the transparent region follow a different arrangement pattern. This local differentiation allows the boundary between regions to be optimized to minimize color shift and interference, thereby maintaining display quality while enabling optical device integration.
