Display Panel Support Bars Prevent Light Leakage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display panels experience light leakage due to weak peripheral support and deformation in the frame area, caused by a large gap between substrates, which leads to ineffective support and structural instability.
Innovation Solution
The display panel incorporates a color resist structure with a first black matrix and first color resist portion arranged in stack, along with support bars between the color resist structure and the substrate, providing enhanced support in the frame area to prevent light leakage and structural deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the gap between substrates is increased to accommodate color resist structure, then the support capability is improved, but the structural stability deteriorates due to deformation
Solution Approach 1:
The support bars are divided into multiple segments with different lengths, where longer support bars are positioned in the frame area and shorter support bars are positioned in the display area. This segmentation allows differential support across the panel, maintaining structural stability while providing enhanced support where needed.
Solution Approach 2:
The patent applies different support bar lengths at different locations: longer support bars in the frame area provide enhanced local support where the substrate gap is larger, while shorter support bars in the display area maintain overall structural stability. This local differentiation resolves the contradiction between needing strong support and maintaining stability.
2Reliability
If support bars are added to enhance peripheral support, then light leakage is reduced, but device complexity increases
Solution Approach 1:
The support bars serve multiple functions: they provide structural support to prevent substrate deformation, maintain the substrate gap for color resist accommodation, and prevent light leakage in the frame area. By combining these functions into a single component, the patent avoids increasing device complexity while improving reliability.
Solution Approach 2:
The support bars are integrated with the color resist structure, combining the support function with the color resist function. This merging reduces the number of separate components needed, thereby preventing an increase in device complexity while still achieving light leakage prevention through enhanced peripheral support.
3Ease of manufacture
If uniform support bars are used across the panel, then manufacturing is simplified, but effective support in frame area is insufficient due to deformation
Solution Approach 1:
Instead of uniform support bars, the patent uses support bars with different lengths positioned at different locations. Longer support bars are placed in the frame area where greater support is needed to counteract deformation, while shorter support bars are placed in the display area. This local differentiation improves support effectiveness while remaining manufacturable.
Solution Approach 2:
The support bar lengths are dynamically adjusted based on the local requirements of different areas. The varying lengths allow the support structure to adapt to the different mechanical demands of the frame area versus the display area, providing effective support without requiring complex manufacturing processes.
