Display Panel Recess for Chip Embedding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display panels experience poor contact between chips and display components when bent, leading to reduced display effectiveness and shortened service life due to separation or deformation of pins.
Innovation Solution
A display panel design featuring a recess portion in the connection area with an exposed gate line layer, where the chip is embedded, and a connecting member with conductive particles and a concave-convex shape to maintain contact and stability even when bent, including a flexible film layer, buffer layer, and insulating layers to enhance connection resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display panel is bent, then flexibility and adaptability are improved, but the contact between chip pins and display component deteriorates
Solution Approach 1:
The recess portion is pre-formed in the display component at the connection area, creating a depression that will accommodate the chip in advance. This preliminary structural preparation ensures that when the panel is bent, the chip is already positioned in a location designed to maintain contact, preventing separation issues that would occur with flat mounting surfaces.
Solution Approach 2:
The recess portion creates a localized structural feature at the connection area between the display component and chip. This local modification allows the surrounding areas to remain flat and stable while the recessed area specifically accommodates the chip, providing differential mechanical properties that maintain contact stability during bending without compromising overall panel flexibility.
2Ease of manufacture
If the chip is mounted on a flat surface, then manufacturing simplicity is maintained, but contact stability during bending deteriorates
Solution Approach 1:
The recess portion is pre-formed in the display component at the connection area, creating a depression that will accommodate the chip in advance. This preliminary structural preparation ensures that when the panel is bent, the chip is already positioned in a location designed to maintain contact, preventing separation issues that would occur with flat mounting surfaces.
3Reliability

AI summary
A display panel is provided. The display panel includes a display component and a chip, wherein the display component includes at least one recess portion and a gate line layer, and the gate line layer is exposed on a bottom surface of the recess portion. The chip is connected to the display component, and at least one portion of the chip is embedded in the recess portion. The present disclosure can prevent a display component in the display panel from being in contact with a chip due to bending of the display panel.
