Electronic Panel Spacer Design for Glare Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic panels face a reduction in visibility and display quality due to internal light leakages, particularly caused by external light being reflected at angles that result in glare, which existing technologies have not effectively addressed.
Innovation Solution
The electronic panel design includes a base substrate with a pixel definition layer and spacers, where the spacers are positioned to control the reflection angles of external light, ensuring that the ratio of the spacer thickness to the total thickness is equal to or greater than 0.3, and the angles of the spacers and signal lines are inclined to reduce light reflection at 30°, thereby minimizing glare and improving visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional display structures are used, then manufacturing is simpler, but visibility is reduced due to internal light leakages and glare from external light reflection
Solution Approach 1:
The patent introduces a spacer layer positioned at a specific height above the pixel definition layer, creating a three-dimensional structure that controls light reflection angles. This vertical dimension allows the spacer to block reflected light from reaching the viewer's eyes, reducing glare without complicating the horizontal layout of the display structure
Solution Approach 2:
The spacer acts as an intermediary element between the pixel definition layer and the external environment. It mediates the interaction between external light and the display by controlling reflection angles, thereby reducing glare while maintaining structural simplicity
2Object-affected harmful factors
If the spacer thickness is increased to control light reflection, then visibility improves, but the ratio of spacer thickness to total thickness must be precisely controlled
Solution Approach 1:
The patent specifies that the spacer thickness should be 1/4 to 1/2 of the pixel definition layer thickness, establishing an optimal parameter range that balances light reflection control with manufacturing feasibility. This quantitative parameter control ensures effective glare reduction without requiring excessive manufacturing precision
