Auxiliary Spacer Design for LCD Panel Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In liquid crystal display panels, spacers can easily slide off pillows and into the display region when subjected to external forces, causing scratches and defects like light leakage. Increasing the number of spacers to prevent this reduces the aperture ratio of pixels, affecting the display effect.
Innovation Solution
A liquid crystal display panel design featuring a plurality of main spacers between substrates and auxiliary spacers around the main spacers, with the auxiliary spacers having a greater height than the main spacers. The auxiliary spacers limit the movement of main spacers, preventing them from sliding into the display region and reducing the need for light-shielding layers.

Engineering Contradiction Analysis
1Reliability
If the number of spacers is increased to prevent scratching of display components, then the reliability of spacer positioning is improved, but the aperture ratio of pixels deteriorates
Solution Approach 1:
The spacer system is segmented into two functional types: main spacers that provide primary support and positioning, and auxiliary spacers that prevent sliding without requiring light-shielding layers. This segmentation allows the auxiliary spacers to be positioned in regions where they do not block light, thus maintaining aperture ratio while improving positioning reliability.
Solution Approach 2:
Auxiliary spacers act as intermediary elements between the main spacers and the display region. They prevent the main spacers from sliding into the display region by providing additional contact points with the pillows, thereby protecting the display components without requiring increased density of light-shielding layers.
2Area of stationary object
If auxiliary spacers are added around main spacers, then the aperture ratio is improved, but the device complexity increases
Solution Approach 1:
The auxiliary spacers are integrated with the main spacers to form a unified spacer assembly. Both types of spacers work together as a coordinated system to maintain cell gap and prevent sliding, where the auxiliary spacers enhance the functionality of the main spacers rather than operating independently.
Solution Approach 2:
The auxiliary spacers are positioned in a different spatial arrangement around the main spacers, utilizing the lateral dimension to provide prevention functionality without occupying the vertical display region. This dimensional arrangement allows them to fulfill their protective role while minimizing impact on aperture ratio.

AI summary
The disclosure provides a liquid crystal display panel and a display apparatus. The liquid crystal display panel of the disclosure includes: first and second substrates assembled to form a cell, a plurality of main spacers therebetween, and an auxiliary spacer around at least a portion of the main spacers. Height of the auxiliary spacer is greater than or equal to that of the main spacer. The display panel further includes: pillows on side of the first substrate close to the second substrate and each abutting against a corresponding main spacer. An orthographic projection of the main spacer on the first substrate falls within an orthographic projection of the pillow on the first substrate, and an orthographic projection of the auxiliary spacer on the first substrate does not overlap with the orthographic projection of the pillow on the first substrate.
