Display Panel Pixel Circuit Segmentation for Seamless Multivision
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge lies in manufacturing very large flat panel display devices with display panels exceeding 100 inches, where multivision apparatuses using multiple panels often exhibit heterogeneity at boundaries due to differing edge regions, affecting visual quality compared to single-panel displays.
Innovation Solution
A display panel design featuring a first region with a specific pixel circuit and a second region with a distinct pixel circuit structure, both configured to collectively display a single image, and a multivision apparatus comprising interconnected display panels with these regions to form a seamless image across the screen.

1Area of stationary object
If multivision apparatuses use a plurality of display panels to form very large displays, then the display size can exceed 100 inches, but heterogeneity appears at the boundaries due to edge regions not displaying images
Solution Approach 1:
The patent applies local quality by implementing different pixel circuit structures in different regions of the display panel. Specifically, edge region pixels use a first pixel circuit structure while inner region pixels use a second pixel circuit structure. This allows each region to be optimized for its specific function, eliminating the heterogeneity at boundaries while maintaining uniform visual quality across the entire display surface.
2Manufacturing precision
If a single display panel is used for very large displays, then visual quality is uniform, but manufacturing becomes difficult and costs increase for panels 100 inches or greater
Solution Approach 1:
The patent applies segmentation by dividing the display panel into multiple regions with different pixel circuit structures. The display panel is segmented into edge regions with first pixel circuits and inner regions with second pixel circuits. This segmentation allows the panel to be manufactured in a modular fashion, improving ease of manufacture while maintaining visual quality uniformity across the entire display.
3Ease of manufacture
If edge regions of display panels are designed for non-display functions, then manufacturing is simplified, but heterogeneity appears at boundaries affecting visual quality
Solution Approach 1:
The patent applies universality by designing pixels in edge regions to serve dual functions. Instead of having edge region pixels serve only non-display functions, they are configured with first pixel circuit structures that enable both display functionality and edge-specific operations. This multi-functionality eliminates heterogeneity at boundaries while maintaining manufacturing simplicity.

AI summary
A multivision apparatus may include a display panel that includes a display screen including a first region and an adjacent second region. The first region may include first pixels, and the second region may include second pixels. The first pixels and the second pixels have different structures. The display panel may display a single image across the first region and the second region of the display screen. The multivision apparatus may include an array of interconnected display panels configured to collectively display an image, based on each given display panel displaying a separate sub-image in the first and second regions of the given display panel.
