Curved LCD Module Isolation-Cushion Distribution for Thickness Uniformity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly process of curved liquid crystal display devices often results in uneven thickness and poor display effects due to improper distribution of isolation-cushion parts, which fail to accommodate varying sustained forces across the screen.
Innovation Solution
A curved liquid crystal display module with densely distributed strip-shaped isolation-cushion parts at the center and sparsely distributed dotted parts towards the edges, made of elastic materials like resin or glass, to maintain uniform thickness and accommodate different sustained forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If isolation-cushion parts are uniformly distributed across the curved screen, then the manufacturing process is simple, but the display effect deteriorates and thickness becomes uneven due to varying sustained forces
Solution Approach 1:
The patent applies local quality by varying the distribution density and shape of isolation-cushion parts according to their position on the curved screen. The center region uses densely distributed strip-shaped isolation-cushion parts, while edge regions use sparsely distributed dotted isolation-cushion parts. This local differentiation compensates for varying sustained forces at different positions, ensuring uniform thickness and optimal display effect across the entire curved screen.
2Manufacturing precision
If isolation-cushion parts are densely distributed at the center, then thickness uniformity is improved, but the device complexity increases
Solution Approach 1:
The patent segments the curved screen into different regions (center and edges) and assigns different isolation-cushion part configurations to each region. The center region receives densely distributed strip-shaped isolation-cushion parts to handle higher sustained forces, while edge regions receive sparsely distributed dotted isolation-cushion parts. This segmentation strategy achieves thickness uniformity without unnecessarily increasing device complexity throughout the entire screen.

AI summary
The present invention provides a curved liquid crystal display module and a liquid crystal display device. The curved liquid crystal display module includes a color filter substrate, an array substrate, and multiple isolation-cushion parts disposed between the color filter substrate and the array substrate. Wherein, the multiple isolation-cushion parts are densely distributed near a center position of the color filter substrate and the array substrate, and the multiple isolation-cushion parts are gradually sparsely distributed toward two edges. Through disposing the isolation-cushion parts to be densely distributed and strip-shaped at the center position, and to be sparsely distributed and dotted toward two edges, the device of the present invention is well suitable for different sustained force at different assembly locations of curved screen such that the curved liquid crystal display module can have a better display effect and an uniform thickness.
