Display Panel Layout With Overlapping Gate Driver and Curved Edge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face challenges in minimizing bezel area and allowing the outer peripheral area to be modified into a curved shape while maintaining high pixel density in the central area.
Innovation Solution
The display device is designed with a substrate divided into a first area at the center and a second area surrounding it, where the gate driver is partially overlapping both areas, and the second area has a lower pixel density, enabling a curved shape and minimized bezel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the gate driver is disposed in a separate area from the pixel array, then the driver can be manufactured independently, but the bezel area increases
Solution Approach 1:
The gate driver is merged with the pixel array by disposing the gate driver area to overlap with the pixel array area. The gate driver is integrated within the display panel area rather than being separate, thereby reducing the bezel area while maintaining manufacturability through coordinated processing of both components together.
Solution Approach 2:
The gate driver is disposed in a region that overlaps both the first area (where first pixels are disposed) and the second area (where second pixels are disposed). This spatial arrangement in multiple overlapping zones allows the gate driver to share space with the pixel array, reducing the overall bezel area while maintaining independent functionality.
2Manufacturing precision
If the outer peripheral area has the same pixel density as the central area, then the display quality is uniform, but the outer peripheral area cannot be curved
Solution Approach 1:
The pixel array is divided into a first area with first pixels at a first pixel density and a second area with second pixels at a second pixel density. This local differentiation allows the outer peripheral area (second area) to have different properties that enable curved shape capability while the central area (first area) maintains high pixel density for uniform display quality.
Solution Approach 2:
The pixel array is segmented into multiple areas with different pixel densities. The first area contains first pixels at a higher density for quality display, while the second area contains second pixels at a lower density that can be curved. This segmentation allows different regions to serve different functional requirements simultaneously.
3Area of stationary object
If the gate driver area overlaps with the pixel array area, then the bezel area is minimized, but the manufacturing process becomes more complex
Solution Approach 1:
The gate driver area is preliminarily designed to overlap with specific regions (first area and second area) of the pixel array. This preliminary spatial arrangement allows both the gate driver and pixel array to be manufactured in a coordinated manner, reducing bezel area while managing manufacturing complexity through pre-planned integration.

AI summary
A display device (1000) includes a display panel (DP) which includes a plurality of pixels and includes a substrate divided into a first area (A1) disposed at the center and a second area (A2a-h) which encloses the first area (A1); and a gate driver including a plurality of stages configured to supply a gate signal to the pixels through gate lines. Each of the plurality of stages included in the gate driver is disposed in a gate area (GIA) which at least partially overlaps the first area (A1) and the second area (A2a-h), the plurality of pixels includes a plurality of first pixels disposed on the first area (A1) and a plurality of second pixels disposed on the second area (A2a-h), and the first pixels may be disposed in the first area at a first density and the second pixels may be disposed in the second area at a second pixel density which is lower than the first pixel density.
