Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dual view liquid crystal display technologies face challenges in achieving high-definition and high-luminance displays due to limitations in light utilization efficiency, pixel pitch, and substrate thickness, which restrict the separation angle and light blocking effects.
Innovation Solution
A liquid crystal display device with a barrier layer featuring a barrier pattern and an intermediate adjustment layer, where the barrier pattern is formed on a substrate and covered by the intermediate layer, allowing for adjustable distance between the color filter and barrier pattern, and incorporating multiple barrier parts with varying light absorption and reflection effects to enhance image separation and luminance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a barrier substrate is bonded onto the liquid crystal panel with UV curable resin to separate left and right images, then dual view display is achieved, but the gap between pixel and barrier pattern increases, reducing image definition
Solution Approach 1:
The invention merges the barrier substrate functionality into the color filter substrate by forming the barrier pattern directly on the color filter substrate. This integration eliminates the need for a separate barrier substrate and UV curable resin bonding layer, thereby reducing the gap between the pixel and barrier pattern while maintaining dual view display capability.
Solution Approach 2:
The invention extracts the barrier pattern formation process from the separate barrier substrate and relocates it to the color filter substrate. This extraction allows for direct formation of the barrier pattern at the pixel level, reducing the gap and improving image definition while preserving the light blocking function for dual view display.
2Manufacturing precision
If the color filter substrate thickness is reduced to decrease the gap, then image definition improves, but substrate strength and handling reliability deteriorate
Solution Approach 1:
The invention combines the barrier pattern formation with the color filter substrate, allowing the barrier pattern to be formed at the desired location without requiring thickness reduction of the color filter substrate. This maintains substrate strength and handling reliability while achieving the desired gap reduction for improved image definition.
3Adaptability or versatility
If a separate barrier substrate is bonded with UV curable resin, then dual view display is achieved, but the total thickness increases, complicating the structure
Solution Approach 1:
The invention merges the barrier substrate functionality into the color filter substrate by forming the barrier pattern directly on it. This integration eliminates the separate barrier substrate and UV curable resin bonding layer, thereby simplifying the overall structure and reducing total thickness while maintaining dual view display capability.
4Adaptability or versatility
If a black matrix is used as the barrier pattern to block light, then image separation is achieved, but light utilization efficiency decreases, reducing luminance
Solution Approach 1:
The invention applies local quality by forming the barrier pattern with selective light blocking properties at specific locations on the color filter substrate. The barrier pattern is designed to block light only in the necessary regions for image separation, while allowing light transmission in other regions, thereby improving light utilization efficiency and luminance compared to a complete black matrix.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enables high-definition and high-luminance dual view displays by optimizing the separation angle and light usage, reducing substrate thickness, and improving light blocking capabilities without the need for separate barrier substrates, thus enhancing overall display performance.
Implementation Method 1
An image separation angle is determined by a relationship between a pixel pitch and a distance between a pixel of the liquid crystal panel and the barrier pattern
Implementation Method 2
Because the black matrix blocks light, high luminance cannot be achieved
Implementation Method 3
bonding a barrier substrate on which a barrier pattern is drawn onto a liquid crystal panel with a UV curable resin
