LCD Panel Buffers and Asymmetric Supporters for Ripple Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid crystal display (LCD) screens experience light leakage and liquid crystal ripples when pressed due to the movement of liquid crystals, which current designs fail to adequately suppress.
Innovation Solution
The introduction of buffers with varying heights between supporters in an LCD panel, which block the flow of liquid crystals and reduce ripples without adding extra supporters, while a black matrix covers the buffers' projection to maintain display functionality.

Engineering Contradiction Analysis
1Object-affected harmful factors
If photo spacers are disposed in each pixel unit as support structure, then light leakage is suppressed when LCD screens are squeezed or pressed, but liquid crystals oscillate and form ripples when external force is removed
Solution Approach 1:
The support structure is segmented into multiple supporters with different heights (first supporters and second supporters) arranged in an array. This segmentation allows different regions to have different support functions, preventing uniform liquid crystal displacement while maintaining overall structural stability and reducing ripple formation.
Solution Approach 2:
The invention uses asymmetrical supporters with different heights (first supporters taller than second supporters) to create a non-uniform support structure. This asymmetry prevents symmetric liquid crystal displacement that causes ripples, while still providing adequate support to suppress light leakage when the display is pressed.
2Object-affected harmful factors
If liquid crystals are pushed toward peripherals when pressed, then light leakage occurs, but adding more supporters increases device complexity
Solution Approach 1:
Different regions of the display have supporters with different heights tailored to local requirements. First supporters in certain regions are taller than second supporters in other regions, providing localized optimization for light leakage suppression without uniformly increasing complexity across the entire device.
Solution Approach 2:
The invention changes the height parameter of supporters to create different support levels. By varying the height parameter of supporters (first supporters vs. second supporters), the structure effectively suppresses light leakage without requiring a proportional increase in the number of supporters, thus avoiding excessive complexity.

AI summary
An LCD panel and an LCD apparatus are provided. The LCD panel comprises a first substrate, a second substrate, a plurality of supporters disposal between the first substrate and the second substrate and configured to support the first substrate and the second substrate, a plurality of liquid crystals filling a space formed by the first substrate, the second substrate, and the plurality of supporters, a plurality of buffers disposed between adjacent supporters, and a black matrix disposed on the second substrate. The plurality of the supporters includes a plurality of first supporters and a plurality of second supporters. In a direction perpendicular to at least one of the first substrate and the second substrate, a second supporter has a height smaller than a first supporter, and a buffer has a height smaller than the first supporter.
