Borderless Display Device Without Cover Glass
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional borderless display devices require expensive cover glass, increasing manufacturing costs and weight, and complicating the manufacturing process due to the need for additional assembly steps.
Innovation Solution
A borderless display device design where the display panel is exposed without a separate cover glass, supported by a guide panel and coupled to a middle frame, using an attaching member and light shielding parts to prevent light leakage and create a seamless, frameless appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a cover glass is used to cover the display module and middle frame, then the display device achieves a borderless appearance, but the manufacturing cost increases, weight increases, and manufacturing time increases
Solution Approach 1:
The patent extracts and removes the cover glass component from the display device structure. Instead of using a separate cover glass to achieve the borderless appearance, the design exposes the display panel directly, eliminating the need for this component and its associated manufacturing steps, thereby reducing cost and complexity while maintaining the borderless aesthetic
Solution Approach 2:
The patent merges the functions of the display panel assembly with the surrounding structure. The middle frame and display panel are integrated in a way that the display panel edges are directly visible without requiring a separate cover glass, combining structural support and aesthetic functions into a unified design
2Shape
If a cover glass is used to cover the display module and middle frame, then the display device achieves a borderless appearance, but the weight of the display device increases
Solution Approach 1:
The patent removes the cover glass component entirely from the structure. By extracting this heavy glass element and replacing it with a direct exposure design where the display panel edges are visible, the overall weight of the display device is reduced while maintaining the desired borderless appearance
3Shape
If a cover glass is used to cover the display module and middle frame, then the display device achieves a borderless appearance, but the manufacturing process becomes more complex and time-consuming
Solution Approach 1:
The patent extracts the cover glass component and its associated attachment processes from the manufacturing workflow. This elimination simplifies the manufacturing process by removing steps related to cover glass installation, handling, and alignment, thereby reducing process complexity and manufacturing time
Solution Approach 2:
The patent segments the display device into distinct functional components (display panel, middle frame, outer case) that can be manufactured and assembled independently. This modular approach simplifies the overall manufacturing process by allowing each component to be optimized and produced separately, then assembled without requiring complex cover glass integration
4Ease of manufacture
If the display panel is exposed without cover glass, then manufacturing cost and weight are reduced, but light leakage may occur at the edges
Solution Approach 1:
The patent introduces a light-shielding member as an intermediary component between the display panel and the surrounding structure. This mediator blocks light leakage paths without requiring a full cover glass, achieving the necessary light control while maintaining the cost-effective exposed design
Solution Approach 2:
The patent applies light-shielding properties locally at specific critical areas where light leakage occurs, rather than covering the entire display area with glass. This targeted approach uses light-shielding material only where needed to prevent leakage, maintaining the overall simplicity and cost-effectiveness of the exposed design
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design reduces manufacturing costs and weight by eliminating the need for cover glass, minimizes non-display regions, and enhances aesthetic quality by creating a flat, frameless surface while effectively blocking light leakage.
Implementation Method 1
The attaching member may have a black color, and may prevent light from being leaked to a side of the display panel
Implementation Method 2
a light shielding part for blocking light transmission may be provided between the display panel and the upper surface of the guide panel
Implementation Method 3
The attaching member may be formed of a material that allows light corresponding to a specific wavelength to be transmitted therethrough

AI summary
Disclosed herein is a borderless display device including a display panel, a cover, and a guide panel between the display panel and the cover. The guide panel is attached to the display panel through an attaching member. The guide panel includes a first light shielding portion protruding from a body portion of the guide panel towards the surface of the display panel, and a second light shielding portion protruding from the body portion towards the surface of the display panel, a first fastening portion protruding from the body portion towards the cover, and a second fastening portion protruding from the body portion towards the cover. The attaching member is disposed between the first light shielding portion and the second light shielding portion. A side surface of the cover protrudes from the planar surface towards the first direction, and is inserted between the first fastening portion and the second fastening portion.
