Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current narrow frame techniques for display devices require cutting the display area of a display panel to form special-shaped screens, which is complex and prevents light emission from the cutting area.
Innovation Solution
A display panel design with a transistor array substrate divided into display, bending, and driving areas, featuring a through-hole in the bending area that forms a light transmitting area when bent, allowing electronic components to be placed under the panel without cutting the display area, thus achieving a narrow frame without compromising light emission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If free-form cutting is performed on the display area to form special-shaped screens, then electronic components can be disposed in the special-shaped area, but the process becomes complicated and the cutting area cannot emit light
Solution Approach 1:
The patent moves the through-hole from the display area to the bending area, utilizing the Z-dimension (depth) by bending the bending area to create a light-transmitting path. This dimensional change allows electronic components to be placed underneath without cutting the display area, resolving the contradiction between component placement flexibility and process complexity
Solution Approach 2:
The bending area acts as an intermediary between the display area and the electronic components underneath. By creating a through-hole in the bending area and bending it, a light-transmitting channel is formed that allows light to pass through to electronic components, eliminating the need to cut the display area while maintaining component placement flexibility
2Adaptability or versatility
If free-form cutting is performed on the display area to form special-shaped screens, then electronic components can be disposed in the special-shaped area, but the cutting area cannot emit light
Solution Approach 1:
The solution utilizes the bending area as a separate zone that, when bent, creates a light-transmitting path in the Z-dimension. This allows light to reach electronic components underneath without removing or cutting any display area, thus preserving light emission capability while enabling component placement flexibility
Solution Approach 2:
The bent bending area with through-hole serves as an optical intermediary that transmits light from the display area to electronic components underneath. This mediator approach allows light to pass through the bending area to illuminate components without the cutting area losing its light emission capability

AI summary
The present disclosure provides a display panel and a display device. A through-hole is defined in a bending area of the display panel, and after the bending area is bent along a bending center line, the through-hole forms a light transmitting area, and the light transmitting area is disposed on a light path of an electronic component. Based on the light transmitting area formed after bending the through-hole, the electronic component can be disposed under the display panel, thereby achieving a narrow frame design.
