Light-Penetrated Adhesive for Narrow Border Display Structural Strength
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional LCD display devices with narrow borders face issues of insufficient structural strength and light leakage or shadowing at the edge of the active area due to the extension of opaque frames and rubber into the pixel region, affecting image quality.
Innovation Solution
A display device design featuring a light-penetrated supporting frame, an optical film assembly, and a light-penetrated adhesive member, where the adhesive member has distinct portions for the non-pixel and pixel regions, and a connecting circuit board with a reflective surface to enhance structural strength and reduce light leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a plastic frame and rubber are used to support the non-pixel region, then structural strength is improved, but light leakage and shadowing occur at the edge of the active area
Solution Approach 1:
The patent changes the optical property of the adhesive member from opaque to light-penetrated (transparent), allowing light to pass through the adhesive member and eliminate shadowing effects at the edge of the active area while maintaining structural support function
Solution Approach 2:
The light-penetrated adhesive member serves as an intermediary component between the frame and the display panel, replacing the traditional opaque rubber seal while maintaining the bonding function and eliminating light leakage issues
2Area of stationary object
If the border width is reduced for narrow border design, then the display area is increased, but structural strength becomes insufficient
Solution Approach 1:
The patent changes the material parameter of the adhesive member from opaque to light-penetrated, enabling the adhesive member to extend into the pixel region and provide structural support while maintaining optical performance for narrow border design
3Area of stationary object
If the frame and rubber are extended to the pixel region, then the border area is reduced, but light leakage occurs at the edge of the active area
Solution Approach 1:
The patent applies the principle of changing optical properties by using a light-penetrated adhesive member instead of opaque rubber, allowing the adhesive member to be extended into the pixel region without causing light leakage or shadowing at the edge of the active area
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

AI summary
A display device includes a supporting frame, a display panel, an optical film assembly, and a light-penetrated adhesive member. The supporting frame includes a first supporting portion, and the display panel is disposed on the supporting frame. The display panel includes a pixel region and a non-pixel region, and the non-pixel region is disposed outside of the pixel region. The optical film assembly is partially disposed between the first supporting portion and the display panel. The light-penetrated adhesive member is disposed between the first supporting portion of the supporting frame and the optical film assembly. The light-penetrated adhesive member includes a first portion disposed corresponding to the non-pixel region and a second portion disposed corresponding to the pixel region. The configuration can achieve the narrow border design, provide a sufficient structural strength, or improve the light leakage or shadow issue at the edge of the active area.
