Display Panel Outer Array Substrate for Flatness Without Cover Glass
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The use of a cover glass in display panels increases costs and hinders lightweight and thin design, while also causing yield loss in the attachment process.
Innovation Solution
A display panel design where the array substrate is positioned on the outer side, covering the color filter substrate, eliminating the need for a cover glass and enhancing panel flatness, thereby simplifying the process and reducing thickness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a cover glass is attached to the outermost side of the LCD to ensure surface flatness, then the flatness is improved, but the cost increases and the thickness increases
Solution Approach 1:
The patent removes the cover glass component from the display panel structure entirely. The array substrate is repositioned to the outermost side where it provides both structural support and surface flatness, eliminating the need for a separate cover glass layer and thereby reducing overall thickness.
Solution Approach 2:
The array substrate is given dual functionality: it serves both as the functional display component and as the protective outermost layer that ensures surface flatness. This multi-functionality eliminates the need for the separate cover glass component.
2Shape
If a cover glass is attached to the outermost side of the LCD to ensure surface flatness, then the flatness is improved, but the cost increases
Solution Approach 1:
The cover glass component is extracted from the structure, eliminating material costs and processing costs associated with acquiring and attaching the cover glass.
Solution Approach 2:
The array substrate performs multiple functions including display functionality and surface protection, eliminating the need for additional components and reducing overall manufacturing costs.
3Shape
If a cover glass is attached to the outermost side of the LCD to ensure surface flatness, then the flatness is improved, but the yield loss increases due to attachment process complexity
Solution Approach 1:
The cover glass attachment process is completely removed from the manufacturing workflow. By eliminating this separate attachment step, the patent avoids the yield losses that occur during the attachment process, including misalignment, bonding failures, and handling damage.
Solution Approach 2:
The protective and flatness-providing functions are merged into the array substrate itself, which is already an integral part of the display panel. This eliminates the need for a separate attachment process and reduces manufacturing complexity.
4Shape
If a cover glass is used in the display panel structure, then the surface flatness is ensured, but the device weight increases
Solution Approach 1:
The cover glass component is removed from the structure, directly reducing the overall weight of the display device while maintaining surface flatness through the repositioned array substrate.

AI summary
The present disclosure relates to a display panel and a display apparatus. The display panel includes an array substrate, a color filter substrate, a driving chip, and a backlight structure; where the driving chip is electrically connected to the array substrate and is configured to control a voltage signal on the array substrate, the driving chip is disposed at an inner side of the array substrate, and the color filter substrate is located between the array substrate and the backlight structure. In the above structure, the array substrate may be covered on the outer side of the color filter substrate and the driving chip, thereby achieving the protection of the structure at an inner side of the array substrate.
