Display Device Drive Element Area Aperture Ratio
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid crystal panels face a reduced aperture ratio due to the presence of scan lines and signal lines formed from low-resistive metal materials within the active area, which also leads to potential moire interference and reduced display quality.
Innovation Solution
The placement of scan lines, signal lines, and switching elements in a drive element area within the peripheral region instead of the light control area, allowing for a higher aperture ratio and preventing overlap with the liquid crystal display panel's scan and video signal lines, thereby enhancing display quality and supporting larger screen sizes with higher resolution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If scan lines and signal lines are arranged in the active area, then the display can function with standard pixel driving, but the aperture ratio is reduced
Solution Approach 1:
The patent moves the scan lines and signal lines from the two-dimensional active area plane to a separate peripheral region, effectively using spatial reorganization to resolve the conflict between functional requirements and aperture ratio optimization
2Reliability
If scan lines and signal lines are placed in the active area, then pixel driving is enabled, but moire interference occurs reducing display quality
Solution Approach 1:
The patent extracts the scan lines and signal lines from the active area and relocates them to the peripheral region, removing the source of moire interference while preserving the essential pixel driving function through alternative routing
3Reliability
If scan lines and signal lines are positioned in the light control area, then electrical connection is established, but the aperture ratio cannot reach 100%
Solution Approach 1:
The patent segments the display structure into distinct functional zones: the light control area dedicated solely to optical functions with 100% aperture ratio, and the peripheral region housing all electrical driving elements, thereby eliminating the trade-off between electrical connection and aperture ratio

AI summary
According to one embodiment, an electronic apparatus includes a first substrate, a second substrate opposed to the first substrate, a liquid crystal layer held between the first substrate and the second substrate, an active area in which pixels are arranged, and a peripheral area positioned in a periphery of the active area. The peripheral area includes a drive element area in which a drive element configured to drive each of the pixels is arranged.
