Bezel-less Display Front Frame Optical Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display apparatuses with bezels appear aesthetically unpleasing due to the bezel's width and material differences from the display panel, and reducing bezel width exposes internal components, making a bezel-less design challenging.
Innovation Solution
A bezel-less display apparatus design featuring a front frame with multiple layers matching the display panel's color and light reflectivity, including a color layer, transparent layer, iodine layer, and anti-reflective coating, to integrate with the display panel and conceal internal components, and a cover member extending to cover side surfaces without a visible bezel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a bezel is provided to cover side surfaces of the display panel, then internal components are concealed and structural integrity is maintained, but the display apparatus appears aesthetically unpleasing and the display area is reduced
Solution Approach 1:
The front frame is designed with a black color that matches the black matrix region of the display panel, making the frame visually blend with the panel and eliminate the aesthetic displeasure caused by traditional bezels while maintaining structural integrity
Solution Approach 2:
The front frame incorporates multiple layers including a reflective layer and a non-reflective layer, creating a composite structure that mimics the optical properties of the display panel while providing mechanical support
2Area of stationary object
If the bezel width is decreased to increase display area, then the display area is increased, but internal components become exposed
Solution Approach 1:
The front frame extends not only horizontally to cover side surfaces but also vertically to cover the lower end of the display panel, using dimensional extension to conceal components while minimizing impact on display area
Solution Approach 2:
The front frame is strategically positioned to cover only specific areas where components are located (side surfaces and lower end), rather than uniformly covering the entire perimeter, thus minimizing the impact on display area while effectively concealing components
3Object-generated harmful factors
If a front frame is provided to conceal components in a bezel-less design, then component coverage is achieved, but light reflectivity mismatch creates visual discontinuity
Solution Approach 1:
The front frame uses a composite structure with a reflective layer having high light reflectivity and a non-reflective layer having low light reflectivity, allowing different portions of the frame to match the optical properties of different regions of the display panel
Solution Approach 2:
Different portions of the front frame have different optical properties: the reflective layer matches the reflective characteristics of the display panel in certain areas, while the non-reflective layer matches the absorptive characteristics in other areas, creating local optical matching to ensure visual continuity
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
The design achieves a sleek, aesthetically pleasing appearance by matching the front frame's color and light reflectivity with the display panel, effectively hiding internal components and eliminating the need for a bezel, thus enhancing the display apparatus's visual appeal and functionality.
Implementation Method 1
A third layer, disposed between the first layer and the second layer, the third layer including a transparent material. The plurality of layers may further include a fourth layer disposed between the second layer and the third layer, the fourth layer including an iodine (I) material.
Implementation Method 2
The plurality of layers includes a second layer disposed in front of the first layer and configured to decrease first light reflectivity of a third front surface of the front frame such that the first light reflectivity of the front frame corresponds to second light reflectivity of the non-display area.

AI summary
Provided is a display apparatus without a front chassis or a bezel. A front frame is provided on at least one side of a display panel to hide a chip-on-film and a printed circuit board coupled to the display panel that would be otherwise exposed to the outside. A front surface of the front frame may have a colour and light reflectivity corresponding to those of a non-display area of the display panel. Thus, the display panel and the front frame may appear to be integrally formed. Accordingly, a bezel-less display apparatus, in which no bezel is formed around the display panel, may be achieved.
