Transparent Display Gate Driver Layout for Zero-Bezel Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display apparatuses with self-light emitting elements face issues such as degradation due to external environmental factors, visibility of bezel areas, and reduced transmittance, which affect reliability and image quality.
Innovation Solution
A display apparatus design featuring a wiring substrate with link wirings and a gate driver disposed on a light emitting part, where display units with light emitting elements are spaced apart and connected via bonding members, allowing the gate driver to be positioned overlapping the light emitting part, thereby minimizing bezel area and maintaining high transmittance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the gate driver is disposed on a separate substrate or in the bezel area, then the reliability is improved by avoiding dim defects, but the bezel area increases and transmittance decreases
Solution Approach 1:
The gate driver is merged with the light emitting part by disposing the gate driver over the light emitting part in a first direction, integrating two previously separate components into a unified structure that eliminates the need for additional bezel space
2Reliability
If the gate driver is disposed on a separate substrate or in the bezel area, then the reliability is improved by avoiding dim defects, but the transmittance decreases
Solution Approach 1:
The gate driver is positioned in a first direction over the light emitting part, utilizing the vertical stacking dimension rather than horizontal expansion, which maintains high transmittance while ensuring reliable operation
3Area of stationary object
If display units are disposed closely together, then the zero bezel area is achieved, but the risk of dim defects increases
Solution Approach 1:
The gate driver is nested within the light emitting part area by disposing it over the light emitting part, allowing display units to be arranged closely without increasing bezel area while maintaining reliability through proper spatial configuration
