Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The deformation between a color filter substrate and a thin film transistor array substrate in the blind hole light transmission region of liquid crystal display panels leads to non-uniform optical display, affecting the screen's optical uniformity.
Innovation Solution
A liquid crystal display panel design featuring a first transparent support in the blind hole light transmission region and second transparent supports in the periphery region, both made of transparent resin, to provide additional support and reduce deformation, with specific structural layers and vias to enhance light transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If a blind hole light transmission region is created to install electronic devices, then the screen-to-body ratio is improved, but substrate deformation and optical uniformity deteriorate
Solution Approach 1:
The patent applies local quality by introducing transparent support structures specifically in the blind hole light transmission region where support is needed, while maintaining the full-screen display appearance. The support structures are transparent to be visually imperceptible, providing localized reinforcement without affecting the overall screen uniformity or aesthetic quality.
2Length of moving object
If the cell thickness is reduced in the blind hole region, then the screen-to-body ratio is improved, but optical uniformity deteriorates due to non-uniform display
Solution Approach 1:
The patent implements local quality by creating a localized support structure in the blind hole region that compensates for the reduced cell thickness. The transparent support maintains the optical path and display uniformity in the thinned region, allowing the overall cell thickness to be reduced while preserving optical performance in the critical blind hole area.
Solution Approach 2:
The transparent support structure acts as an intermediary element between the substrates in the blind hole region. It mediates the mechanical stress and maintains the optical properties, allowing light to pass through while providing the necessary structural support for the thinned cell configuration.
3Stability of the object's composition
If transparent support structures are added to prevent substrate deformation, then optical uniformity is improved, but device complexity increases
Solution Approach 1:
The patent applies the color changes principle by using transparent support structures that are optically invisible. The supports have the same refractive index as the surrounding medium, making them imperceptible in the finished display. This allows complex structural support to be added without increasing visual complexity or affecting the aesthetic appearance of the display.

AI summary
A liquid crystal display panel includes a blind hole area, which includes a blind hole light transmission region and a blind hole periphery region surrounding the blind hole light transmission region. A first transparent support is disposed on a color filter substrate in the blind hole light transmission region, and the first transparent support is configured to support the color filter substrate and a thin film transistor array substrate in the blind hole light transmission region. A black matrix is disposed on the color filter substrate in the blind hole periphery region, and a plurality of second transparent supports are disposed corresponding to the black matrix. A problem with optical uniformity of a display panel can be resolved by the first transparent support located in the blind hole light transmission region.
