Hybrid Display Panel Structure for Narrow-Bezel Screen Splicing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional LCD panels have large pitches when spliced, affecting visual effect, while Mini LED and micro LED panels have lower resolution and higher costs, making it challenging to reduce the gap between spliced screens effectively.
Innovation Solution
A hybrid panel is designed with an LED substrate in the non-display region, increasing the display area and reducing the pitch between adjacent display regions by thinning the LED substrate and using side or back surface bonding techniques to minimize bezel width.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If LCD panels are spliced, then large size display is achieved, but large pitch between display regions affects visual effect
Solution Approach 1:
The patent combines LCD and LED technologies into a hybrid panel structure. The LCD panel provides the main display area with high resolution, while the LED substrate is integrated into the non-display region to emit light and reduce the visible pitch between spliced panels, creating a unified visual effect that merges the advantages of both display technologies
Solution Approach 2:
The LED substrate is positioned in the non-display region (bezel area) of the LCD panel, utilizing the lateral dimension rather than competing for display space. This dimensional placement allows the LED to reduce the pitch between spliced panels without compromising the LCD's resolution, effectively addressing the gap issue in the horizontal dimension while maintaining vertical display quality
2Length of stationary object
If Mini LED or micro LED panels are used, then pitch between display regions is reduced, but resolution decreases and cost increases
Solution Approach 1:
The patent applies different display technologies to different regions of the panel. The LCD technology is used in the main display region where high resolution is critical, while the LED technology is applied locally in the non-display region where its primary function is to reduce pitch and emit light, not to provide high-resolution imagery. This local differentiation allows each technology to excel in its designated area
3Area of stationary object
If LED substrate is integrated in non-display region, then display area is increased and pitch is reduced, but manufacturing complexity increases
Solution Approach 1:
The LED substrate serves multiple functions simultaneously: it acts as a light source to reduce the pitch between spliced panels, it forms part of the hybrid display structure to increase effective display area, and it provides structural support for the overall panel assembly. This multi-functionality reduces the need for separate components, thereby managing manufacturing complexity despite the hybrid nature of the panel
