Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid crystal display devices face inefficiencies in light incident efficiency due to the shape of the side surfaces of the substrates, which affects the propagation and scattering of light, leading to reduced luminance and display quality.
Innovation Solution
The configuration of the liquid crystal display device includes a first substrate and a second substrate with a liquid crystal layer in between, featuring side surfaces with specific inclined angles and shapes that optimize light incident efficiency by controlling the protrusion and alignment of end portions, thereby enhancing light transmission and scattering for improved display performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If light is made incident on the side surface of the array substrate or counter-substrate, then light can be introduced into the liquid crystal layer, but the incident light efficiency is reduced due to the shape of the side surface causing light scattering and loss
Solution Approach 1:
The patent applies curvature to the side surface of the substrate by forming an inclined surface that extends from the side surface toward the liquid crystal layer. This curved/inclined structure guides light more effectively into the liquid crystal layer, reducing scattering and improving incident light efficiency while minimizing energy loss.
2Ease of manufacture
If the side surface of the substrate has a conventional shape, then manufacturing is simple, but light propagation and scattering are adversely affected, reducing luminance and display quality
Solution Approach 1:
The patent changes the geometric parameters of the side surface by forming an inclined surface with a specific angle (θ) relative to the side surface. This parameter modification optimizes light propagation and scattering characteristics, enhancing luminance and display quality while remaining compatible with conventional manufacturing processes.
