Solution Overview

Problem

Existing AMOLED display structures face challenges in miniaturization due to the need for additional circuit boards to house driver chips and control circuits, leading to space inefficiencies in electronic devices.

Innovation Solution

A flexible display structure with a bendable substrate and integrated functional assemblies, including a TFT array layer, light emitting layer, and touch control layers, where the substrate is connected through bendable regions with metal wiring, allowing for the integration of driving chips, sensors, and electromagnetic shielding, thereby reducing internal space requirements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If driver chips and control circuits are provided on additional circuit boards, then device functionality is complete, but internal space of the electronic device increases

Engineering Contradiction:

Improvedevice functionalityVSAvoidinternal space

Core Design Contradiction:

ReliabilityVSVolume of stationary object

Solution Approach 1:

The patent merges the driver chip and control circuit from separate circuit boards into the display module itself. The driver chip is integrated into the display assembly, and the control circuit is incorporated within the same structural unit, eliminating the need for additional standalone circuit boards and reducing overall device volume while maintaining complete functionality.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The display module is designed to perform multiple functions simultaneously: it serves as both the display interface and the housing for driver chips and control circuits. This multi-functional integration allows a single component to fulfill multiple roles that previously required separate dedicated components, thereby saving space.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If multiple separate components are used for display and control functions, then functional independence is maintained, but device complexity increases

Engineering Contradiction:

Improvefunctional independenceVSAvoidnumber of components

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines multiple functional components into an integrated display assembly where the display panel, driver chip, and control circuit coexist within a unified structure. This merging reduces the total number of discrete components and simplifies the overall device architecture while preserving the functional independence of each subsystem through dedicated integration zones.

Inventive Principle:

Principle #5Merging (Combining)
