Liquid Crystal Display Assembly Vertical Component Stacking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current liquid crystal display assemblies face a challenge in achieving high light transmittance due to the increased non-transparent area required for more pixel units and thin-film transistors, which reduces the window area and light transmittance.
Innovation Solution
The liquid crystal display assembly design includes a first substrate with thin-film transistors, pixel parts, and empty parts, and a second substrate with corresponding components, where projections of the first substrate's components cover the second substrate's components, optimizing the arrangement to decrease the non-transparent area and increase light transmittance by aligning and staggering red, green, and blue pixels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If more pixel units and thin-film transistors are disposed to achieve high resolution, then display resolution is improved, but non-transparent area increases and light transmittance decreases
Solution Approach 1:
The patent applies dimensional change by stacking thin-film transistors and pixel parts in the vertical dimension (one on first substrate, one on second substrate) rather than only in the planar dimension. This allows more components to be packed into the same display area without increasing the non-transparent area in the light path direction, thereby maintaining high light transmittance while achieving high resolution.
Solution Approach 2:
The patent implements nesting by placing the first thin-film transistor on the first substrate and the second thin-film transistor on the second substrate such that they are positioned at the same vertical level, with the first pixel part and second pixel part overlapping in the vertical direction. This nested arrangement allows multiple functional elements to occupy the same spatial footprint, reducing the overall non-transparent area and improving light transmittance.
2Measurement precision
If more thin-film transistors are disposed to increase pixel units, then display resolution is improved, but window area decreases
Solution Approach 1:
The patent resolves this contradiction by utilizing the vertical dimension to accommodate additional thin-film transistors and pixel parts. By positioning components on both the first and second substrates at corresponding vertical levels, the design increases component density without reducing the window area, as the overlapping arrangement maintains the same light path cross-section.
Solution Approach 2:
The patent merges the first thin-film transistor and second thin-film transistor into a vertically integrated structure, along with the overlapping pixel parts. This merging of multiple components into a compact vertical assembly allows more pixel units to be packed into the same display area, thereby maintaining or increasing window area while improving display resolution.

AI summary
A liquid crystal display assembly is provided. The liquid crystal display assembly includes a first substrate, a second substrate, and a liquid crystal layer. First component units are disposed on a bottom surface of the first substrate. Second component units are disposed on a top surface of the second substrate. The first component units and the second component units have a one-to-one correspondence. A first thin-film transistor and a second thin-film transistor overlap with each other along a direction perpendicular to the first substrate and the second substrate.
