Solution Overview

Problem

The thickness of the drive chip in flexible display screens causes the screen body to bend, affecting the display effect due to its thickness, which complicates manufacturing and increases costs.

Innovation Solution

Incorporating a groove in the support structure to receive the drive chip, ensuring it does not protrude and bend the screen, thereby maintaining display quality while simplifying the manufacturing process and reducing costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the drive chip is positioned below the support structure, then the flexible substrate can be supported properly, but the thickness of the drive chip causes the screen body to bend and affects display effect

Engineering Contradiction:
Improvesupport functionVSAvoidscreen body bending
Core Design Contradiction:
ReliabilityVSShape

Solution Approach 1:

The support structure is designed with a groove at the position where the drive chip is located, creating a local recessed structure. This allows the drive chip to be embedded into the groove, making the surface of the support structure flush with the top of the drive chip, thereby preventing screen body bending while maintaining proper support function.

Inventive Principle:
Principle #3Local quality

2Shape

If additional support structures like double-sided tapes are used to prevent bending, then display effect is maintained, but manufacturing complexity and costs increase

Engineering Contradiction:
Improvescreen body flatnessVSAvoidmanufacturing complexity
Core Design Contradiction:
ShapeVSDevice complexity

Solution Approach 1:

The support function and the bending prevention function are merged into a single integrated support structure. The groove is formed as an integral part of the support structure through molding or machining, eliminating the need for separate components like double-sided tapes or additional support elements, thereby simplifying manufacturing while maintaining screen body flatness.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

Disclosed are a flexible display screen and a flexible display apparatus. The flexible display screen comprises a display device (21), a flexible substrate (22), a support structure (23) and a drive chip (24). The display device (21) is positioned on the flexible substrate (22), and the flexible substrate (22) is positioned on the support structure (23). A groove (25) is provided in the support structure (23), and the groove (25) is used to receive the drive chip (24). Since the groove (25) for receiving the drive chip (24) is provided in the support structure (23) of the flexible display screen. The drive chip (24) will not cause the screen body of the flexible display screen to bend, thereby not affect the display effect of the flexible display screen.
