Edge Bending Display Panel with Compensating Pixel for Uniformity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bending display devices face challenges in maintaining uniform display quality between flat and bending areas due to color and brightness differences, which affect user immersion and screen experience.
Innovation Solution
Incorporating a compensating pixel in the bending area of the edge bending display panel, which emits the same or matching color as the primary pixels, helps to minimize color and brightness differences, ensuring consistent display quality across both flat and bending regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a bending display device uses a uniform pixel structure across the entire display area, then the device structure is simple and easy to manufacture, but color and brightness differences occur between the flat area and the bending area, degrading display quality
Solution Approach 1:
The patent applies local quality by configuring different pixel structures in different regions of the display. Specifically, the bending area includes a compensating pixel with a different structure or configuration compared to the standard pixels in the flat area. This compensating pixel is designed to compensate for the color and brightness differences that occur when the display is bent, thereby maintaining uniform display quality across both flat and bending regions without requiring a completely different overall pixel structure
2Manufacturing precision
If the display panel includes additional compensating pixels in the bending area, then display quality and color uniformity are improved, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent implements local quality by introducing compensating pixels only in the bending area rather than throughout the entire display. This localized approach allows the patent to address the display quality issues in the bending region without significantly increasing the overall complexity of the device. The compensating pixels are strategically placed where needed to compensate for bending-induced color and brightness differences, while the majority of the display area maintains the standard, simpler pixel structure
Solution Approach 2:
The patent applies parameter changes by modifying the configuration or properties of the compensating pixel relative to the standard pixels. This could involve changing the pixel dimensions, the arrangement of sub-pixels, or other structural parameters to create a pixel that compensates for the optical distortions occurring in the bending area. By adjusting these parameters locally, the patent achieves improved display quality without requiring a complete redesign of the entire pixel structure
