Display Panel Reflection Reduction Member for Thin Bezel Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices face challenges in minimizing thickness and enhancing aesthetic appearance due to the presence of a top case that increases thickness and creates a stepped surface, reducing the sense of beauty in design, and the bezel width that affects visual appeal.
Innovation Solution
A display device design featuring a reflection reduction member on the outer substrate to reduce external light reflectivity and static electricity, including a non-reflective conductive pattern and an electricity removing layer, which are integrated into the structure to minimize thickness and enhance visual appeal by eliminating the need for a separate external cover and reducing bezel width.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a top case is provided to cover the panel driver, then the panel driver is protected from exposure, but the thickness of the display device increases and a stepped portion is formed at the front surface
Solution Approach 1:
The top case is merged with the display panel by forming it as an integral part of the panel structure. The case is formed to extend along the front surface of the display panel, eliminating the need for a separate protective cover and reducing overall thickness while maintaining protection functionality.
Solution Approach 2:
The case is designed to extend along the front surface dimension of the display panel rather than adding thickness in the vertical dimension. This dimensional approach allows the case to provide protection without increasing the display device thickness.
2Reliability
If a top case is provided to cover the panel driver, then the panel driver is protected from exposure, but a stepped portion is formed at the front surface reducing sense of beauty
Solution Approach 1:
The top case is merged with the display panel structure, creating a seamless integration that eliminates stepped portions at the front surface. The case is formed to extend along the front surface of the display panel, providing protection while maintaining a flush, aesthetically pleasing surface.
3Reliability
If a separate external cover is used to protect the panel driver, then protection is achieved, but device complexity and manufacturing steps increase
Solution Approach 1:
The protective case is merged with the display panel as an integral component. The case is formed to extend along the front surface of the display panel, eliminating the need for a separate external cover and reducing device complexity.
Solution Approach 2:
The display panel structure is designed to serve multiple functions: it provides the display functionality and simultaneously forms the protective case structure. This multi-functionality eliminates the need for separate protective components.
4Shape
If bezel width is reduced to enhance aesthetic appearance, then visual appeal is improved, but space for panel driver connections is reduced
Solution Approach 1:
The panel driver connections are moved to the side surfaces of the display panel rather than requiring horizontal space in the bezel area. This vertical/dimensional relocation allows for reduced bezel width while maintaining adequate connection space.

AI summary
Disclosed is a display device. The display device includes a display panel, which includes a display area and a non-display area surrounding the display area, and a panel driver connected to the display panel in the non-display area of the display panel. The display panel includes an outer substrate configured to include a gate line and a data line that intersect with each other, an inner substrate coupled to a bottom of the outer substrate, and a reflection reduction member formed on the outer substrate to overlap at least one selected from the gate line and the data line, and configured to reduce a reflectivity of external light by a line.
