Liquid Crystal Panel Light Blocking Strips Parallax Barrier
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manufacturing of parallax barrier displays is prone to inaccuracies due to manual processes, and the presence of an air layer between the parallax barrier and the display surface leads to light reflection and deterioration in displaying quality.
Innovation Solution
The solution involves forming light blocking strips on the array substrate and/or the color filter substrate, opposite to the side holding the liquid crystal layer, eliminating the need for a parallax barrier and reducing light interference by integrating the light blocking strips directly into the liquid crystal panel structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a parallax barrier is attached manually onto the display surface, then the stereoscopic display function is achieved, but the manufacturing accuracy is hard to be ensured and the process is complex
Solution Approach 1:
The patent merges the parallax barrier function directly into the liquid crystal panel structure by forming light blocking strips on the array substrate or color filter substrate. This integration eliminates the need for a separate parallax barrier component and manual attachment process, thereby ensuring manufacturing accuracy while maintaining the stereoscopic display function.
Solution Approach 2:
The array substrate or color filter substrate is given multiple functions: it serves as both the liquid crystal panel component and the parallax barrier. The light blocking strips formed on these substrates simultaneously perform the functions of liquid crystal display and stereoscopic parallax barrier, simplifying the overall structure and manufacturing process.
2Reliability
If a parallax barrier substrate with light blocking strips is attached onto the display, then the stereoscopic effect is achieved, but the device complexity increases due to additional components and assembly steps
Solution Approach 1:
The patent combines the parallax barrier function with the liquid crystal panel structure by forming light blocking strips directly on the array substrate or color filter substrate. This merger eliminates the need for a separate parallax barrier substrate and reduces the number of components, thereby simplifying the device structure while maintaining the stereoscopic effect.
3Ease of manufacture
If an air layer is maintained between the parallax barrier and display surface, then the parallax barrier can be attached, but light reflection and refraction occur which deteriorate the displaying quality
Solution Approach 1:
The patent merges the light blocking function directly into the liquid crystal panel structure, eliminating the air layer between the parallax barrier and display surface. By forming light blocking strips on the array substrate or color filter substrate, the invention removes the interface that causes light reflection and refraction, thereby improving display quality while maintaining manufacturing ease.
