Gate-in-Panel Driver Integration for Narrow Bezel Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current light emitting display technologies face limitations in downsizing the non-display area, particularly with the gate-in-panel system, which restricts further reduction in bezel width.
Innovation Solution
The solution involves integrating the gate driver within the display area and providing a low voltage supply line in the non-display area, allowing for a more compact design by minimizing the number of lines in the non-display area while maintaining reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the gate driver is disposed in the non-display area (gate-in-panel system), then the gate driver can be integrated into the display panel, but the non-display area width cannot be sufficiently reduced
Solution Approach 1:
The gate driver is extracted from the non-display area and relocated to the display area, allowing the non-display area to be minimized while maintaining gate driver functionality through alternative positioning
Solution Approach 2:
The gate driver is moved from a horizontal arrangement in the non-display area to a vertical arrangement along the gate lines in the display area, utilizing the vertical dimension to achieve compact integration without increasing bezel width
2Area of stationary object
If minimum lines are disposed in the non-display area, then the bezel can be narrowed, but the reliability of voltage supply may be compromised
Solution Approach 1:
The voltage supply system is segmented into high voltage lines for the light emitting diodes and separate low voltage supply lines for the pixel driving circuits, allowing independent optimization of each voltage path and ensuring reliable power delivery to different functional blocks
Solution Approach 2:
Display area low voltage supply lines act as intermediaries, extending voltage supply from the non-display area into the display area to ensure stable power delivery to pixel driving circuits while maintaining a compact overall design

AI summary
A light emitting display panel and a light emitting display apparatus using the same are disclosed, in which a gate driver is built in a display area and a low voltage supply line is provided in a non-display area. Each pixel in the display area includes a light emitting diode and a pixel driving circuit for driving the light emitting diode. The light emitting diode is connected with a high voltage line to which a first driving voltage is supplied, and is connected with a display area low voltage supply line to which a second driving voltage is supplied.
