Gate Driver Transparent Parts for Display Uniformity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transparent display devices exhibit visual inconsistencies between the display area and non-display areas, such as bezels, due to differences in appearance.
Innovation Solution
A gate driver is designed with circuit parts and transparent parts arranged in a manner that allows external light to pass through, with the circuit parts configured to perform specific functions and include extensions for wiring, ensuring a uniform visual appearance across the display and non-display areas by matching the size and shape of circuit parts in both areas.

If the gate driver is disposed in the non-display area with conventional circuit layout, then the circuit functionality is achieved, but the visual appearance becomes inconsistent between display and non-display areas
Solution Approach 1:
The gate driver circuit is divided into multiple circuit parts (first circuit part, second circuit part, third circuit part, etc.) that are disposed at different locations within the non-display area. Each circuit part contains specific circuit elements (transistors, capacitors, wirings) that perform specific functions. This segmentation allows the circuit to maintain functionality while achieving uniform visual appearance by distributing components across the non-display area rather than concentrating them in one location.
Solution Approach 2:
Different circuit parts are disposed at different locations within the non-display area, with each location having specific circuit elements configured for local functionality. For example, the first circuit part is disposed at a first location with specific transistors and capacitors, while the second circuit part is disposed at a second location with different circuit elements. This local quality approach ensures that each region of the non-display area has the appropriate circuit characteristics while maintaining overall visual uniformity with the display area.

If transparent parts are added between circuit parts to improve transparency, then visual consistency is improved, but device structure becomes more complex
Solution Approach 1:
The transparent parts are integrated into the existing circuit structure by disposing them between the circuit parts that are already distributed in the non-display area. The transparent parts serve dual purposes: they maintain electrical isolation between circuit parts while simultaneously improving light transmission and visual consistency. This merging approach combines the electrical function with the optical function without adding separate structural elements.
