Flexible Driving Circuit Substrate Bending for Full-Screen Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display panels cannot achieve a full screen display with a front screen ratio of 100% due to their narrow bezel design, limiting the user experience.
Innovation Solution
The design of an array substrate with a flexible driving circuit substrate that includes a pixel driving circuit in the display area, a gate driving circuit on the sides, and a data driving circuit below, which is bonded to a support plate with the gate and data driving circuits partially bent to the other surface, ensuring only the display area is on the light-emitting surface, thereby increasing the screen ratio.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the gate driving circuit and data driving circuit are disposed on the front surface of the display area, then the driving circuits can be easily connected, but the screen ratio is reduced due to the occupation of display area
Solution Approach 1:
The patent moves the gate driving circuit and data driving circuit from the front surface (2D plane) to the back surface of the display panel, utilizing the third dimension (depth/thickness) to resolve the conflict between connection ease and screen ratio. This allows the driving circuits to be connected while not occupying the front display area, thereby maintaining high screen ratio.
Solution Approach 2:
The driving circuits are nested within the back surface structure of the display panel, specifically disposed in grooves formed on the back surface. This nesting approach allows the driving circuits to be integrated into the panel structure without protruding or occupying additional space, thus maintaining a sleek profile and high screen ratio.
2Area of stationary object
If the bezel is made narrow to approach full screen display, then the screen ratio is improved, but the driving circuits cannot be properly disposed
Solution Approach 1:
By transferring the driving circuits to the back surface dimension, the patent enables narrow bezel design on the front surface while providing adequate space on the back surface for driving circuit disposal and connection, thus resolving the contradiction between screen ratio and manufacturing ease.
3Area of stationary object
If the driving circuits are disposed on the back surface in grooves, then the screen ratio is improved, but the connection process becomes more complex
Solution Approach 1:
The patent segments the display panel into distinct functional zones: the front surface for display area and the back surface for driving circuit disposal. The grooves on the back surface further segment the space to organize different driving circuits, making the complex connection process more manageable and systematic.

AI summary
The application provides an array substrate, a display panel, and a display device. The display panel comprises the support plate and the array substrate. The backlight surface of the flexible driving circuit substrate of the array substrate is bonded to the support plate in the display area. The area where the flexible driving circuit substrate is provided with the gate driving circuit and the data driving circuit is bent and attached to the other surface of the support plate. The light emitting surface of the display panel only has a display area capable of displaying pictures, which alleviates the problem that the existing display panel cannot fully display.
