Narrow Bezel Flat Panel Display Recessed Connection Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing narrow bezel flat panel displays face limitations in reducing the bezel area due to the presence of a connection member that increases the non-display area, degrading the aesthetic quality.
Innovation Solution
A recess is formed on the end side of the thin film transistor substrate to allow the connection member to pass through, minimizing the bezel area and preventing damage by reducing the distance between the connection member and other structural components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a connection member is disposed along one end of the thin film transistor substrate to connect the display panel and driving unit, then the electrical connection is achieved, but the bezel area increases due to the required spacing for the connection member
Solution Approach 1:
The connection member is extracted from the traditional position along the end edge of the thin film transistor substrate and relocated to pass through a recess formed on the end surface. This extraction from the harmful position eliminates the need for additional spacing that would otherwise increase the bezel area, while maintaining the essential electrical connection function.
Solution Approach 2:
The connection member is transitioned from a planar arrangement along the end edge to a three-dimensional arrangement passing through a recess. By utilizing the vertical dimension and forming a recess on the end surface, the connection member can be positioned without increasing the horizontal bezel area, effectively moving the problem from a two-dimensional constraint to a three-dimensional solution.
2Reliability
If additional spacing is provided to prevent friction and damage to the connection member, then the connection member is protected, but the non-display area increases
Solution Approach 1:
The connection member is nested within a recess formed on the end surface of the thin film transistor substrate. This nesting structure allows the connection member to be protected from friction and damage by surrounding structural components while occupying minimal additional space, as the recess utilizes the existing thickness dimension rather than requiring additional lateral spacing.
Solution Approach 2:
The recess structure provides beforehand cushioning and protection for the connection member by surrounding it with structural components. This preventive design eliminates the need for additional spacing to prevent friction and damage, as the connection member is already protected by its position within the recess before any potential contact with other components.

AI summary
A flat panel display includes a display panel comprising a display area and a non-display area which is disposed on a outside of the display area and has at least one recess on one end side thereof; a driving substrate disposed on a rear surface of the display panel; and at least one connection member connected to the display panel and the driving substrate through at least one recess.
