Solution Overview

Problem

The existing liquid crystal display devices in notebook computers face interference issues during touch control due to the design of the housing and display module, leading to a less-than-ideal user experience and increased costs with the addition of a protective cover plate.

Innovation Solution

The display device incorporates a design where the array substrate is flipped, allowing the first polarizer to function as a protective cover, eliminating the need for a separate protective cover plate and integrating components within the display module, thus simplifying manufacturing and improving aesthetics.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a protective cover plate is added to eliminate interference during touch control, then the touch control experience is improved, but the device thickness and cost increase

Engineering Contradiction:
Improvetouch control experienceVSAvoiddevice thickness
Core Design Contradiction:
Ease of operationVSLength of moving object

Solution Approach 1:

The patent merges the protective cover plate function with the array substrate by flipping the array substrate and using its front surface as the protective cover. This integration eliminates the need for a separate protective cover plate, reducing device thickness while maintaining touch control functionality.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The array substrate is given multiple functions: it serves as both the display control component and the protective cover plate. By flipping the array substrate, its front surface becomes the external protective surface, allowing one component to fulfill multiple roles and eliminate the need for additional parts.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Length of moving object

If the array substrate is flipped to use the first polarizer as protective cover, then the device thickness is reduced, but the manufacturing complexity increases

Engineering Contradiction:
Improvedevice thicknessVSAvoidmanufacturing complexity
Core Design Contradiction:
Length of moving objectVSDevice complexity

Solution Approach 1:

The patent applies inversion by flipping the array substrate upside down, so that the front surface with the first polarizer becomes the external protective surface. This inverted configuration reduces device thickness while the patent addresses manufacturing complexity through optimized assembly processes.

Inventive Principle:
Principle #13The other way round (Inversion)

4Area of stationary object

If the array substrate is flipped to integrate components, then the screen-to-body ratio is enhanced, but the manufacturing process becomes more complex

Engineering Contradiction:
