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

VSEngineering 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

Engineering Contradiction:
Improveelectrical connectionVSAvoidbezel area
Core Design Contradiction:
ReliabilityVSArea of stationary object

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.

Inventive Principle:
Principle #2Taking out (Extraction)

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.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

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

Engineering Contradiction:
Improveconnection member protectionVSAvoidnon-display area
Core Design Contradiction:
ReliabilityVSArea of stationary object

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.

Inventive Principle:
Principle #7Nested doll (Nesting)

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.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)
