Capacitor Placement in Gate Driving Circuits for Narrow Border Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display panels face challenges in achieving a narrow border design due to the additional width contributed by capacitors in gate driving circuits, which hinders the reduction of border width and affects display efficiency.
Innovation Solution
The capacitors are strategically arranged above or below the signal lines in the array substrate, eliminating their contribution to the border width and allowing for a more compact design by integrating them within the signal line regions, thereby reducing the overall border width.

If capacitors are arranged in conventional gate driving circuits, then the gate driving circuit function is achieved, but the border width increases
Solution Approach 1:
The capacitor is moved from a planar arrangement to a three-dimensional arrangement by placing it above or below the signal line, utilizing the vertical dimension to eliminate the capacitor's contribution to border width while maintaining its electrical function
Solution Approach 2:
The capacitor is nested within the signal line region by positioning it above or below the signal line, allowing the capacitor to occupy space that does not increase the border width while still performing its function

AI summary
An array substrate, a display panel and a display apparatus are provided. The array substrate includes a display region and a non-display region. The non-display region is provided with multiple gate driving circuits and multiple signal lines disposed outside the gate driving circuits. Each gate driving circuit includes at least one Thin Film Transistor and at least one capacitor. The capacitor includes a first plate and a second plate, and the capacitor is located above or below the signal lines. Since the capacitor is not arranged in a gate driving circuit region, a size of the gate driving circuit may be reduced. Accordingly, a width of a border of the display apparatus is further reduced, thereby achieving a narrow border design.
