Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current liquid crystal display (LCD) devices face challenges in enhancing image quality due to limitations in light control and color layer arrangement, leading to suboptimal brightness and color accuracy.
Innovation Solution
The proposed display device incorporates a unique arrangement of color layers and light blocking layers between substrates, with differently sized color layers emitting distinct colors and strategically placed light blocking portions to optimize light transmission and control, along with a polarization layer to enhance image quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional uniform color layer arrangement is used, then manufacturing is simple, but image quality and color accuracy are insufficient
Solution Approach 1:
The patent applies local quality by making different color layers (first, second, and third color layers) have different sizes and arrangements within the pixel. Specifically, the first color layer has a first size, the second color layer has a second size, and the third color layer has a third size, with light blocking portions strategically placed at different locations for each color layer. This non-uniform local arrangement optimizes light transmission and color accuracy for each color channel, thereby improving overall image quality without requiring complete redesign of the entire display structure.
Solution Approach 2:
The patent segments the color layer structure by dividing the pixel into multiple distinct color layers (first, second, and third color layers) with different sizes and positions, rather than using a uniform color layer arrangement. Each color layer is further segmented with dedicated light blocking portions placed at specific locations. This segmentation allows independent optimization of each color channel's light transmission characteristics, improving color accuracy and image quality while maintaining a manageable manufacturing process.
2Manufacturing precision
If light blocking portions are strategically placed, then color accuracy improves, but device complexity increases
Solution Approach 1:
The light blocking layer applies local quality by placing light blocking portions at different locations corresponding to different color layers. The first light blocking portion is positioned for the first color layer, the second light blocking portion for the second color layer, and the third light blocking portion for the third color layer. Each light blocking portion is strategically located to control light transmission for its corresponding color, optimizing color accuracy through localized light management rather than uniform light blocking across the entire pixel.
3Illumination intensity
If differently sized color layers are used, then brightness and color representation improve, but manufacturing precision requirements increase
Solution Approach 1:
The patent implements local quality by assigning different sizes to different color layers based on their specific optical requirements. The first color layer has a first size optimized for its brightness and color transmission needs, the second color layer has a second size suited to its requirements, and the third color layer has a third size. This localized size optimization for each color layer improves overall brightness and color representation, while the systematic arrangement with corresponding light blocking portions helps manage the manufacturing precision requirements.

AI summary
A display device is capable of improving image quality including: a first and second substrate; a first and second color layer adjacent to each other between the first and second substrate, and arranged along a first direction; a third color layer including a first divided color layer adjacent to the first color layer in a second direction and a second divided color layer adjacent to the first divided color layer the first direction and adjacent to the second color layer in the second direction; a light blocking layer including a light blocking portion between the first and second color layer and a light blocking portion between the first and second divided color layer. The first, second and third color layer emit lights of different colors and at least two of them have different sizes. A width of the first and second light blocking portion is substantially equal.
