Window Member Air Gaps for Bezel Color Definition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face challenges in aesthetically integrating a bezel area with the transmission area, often resulting in step differences and potential damage during manufacturing, which can lead to issues like delamination and bubble formation when coupled with other elements.
Innovation Solution
A display device with a window member that includes a base member with air gaps of varying sizes for the bezel area, filled with color particles, and an insulating layer, allowing for a seamless integration of the bezel with the transmission area, reducing step differences and preventing delamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a separate bezel component is used to define the bezel area, then the bezel can be clearly defined and provide aesthetic design, but step differences occur between the bezel area and transmission area, and delamination or bubble formation may happen during coupling
Solution Approach 1:
The patent merges the bezel area and transmission area into a single integrated window member structure. The window member includes a single substrate with both the transmission area (for displaying images) and the bezel area (for aesthetic design and circuit protection) formed as one unified component, eliminating the need for separate bezel components and preventing delamination or bubble formation at interfaces.
2Shape
If a separate bezel component is used, then the bezel can be defined, but manufacturing complexity increases and potential damage occurs during coupling with other elements
Solution Approach 1:
The patent combines the window member and bezel into a single integrated component, reducing the total number of parts and assembly steps. This integration simplifies the manufacturing process by eliminating the need to separately manufacture, handle, and couple a separate bezel component, thereby reducing manufacturing complexity and the risk of damage during assembly.
3Illumination intensity
If the window member is made completely transparent for the transmission area, then image transmission is optimized, but the bezel area cannot be aesthetically integrated without appearing as a separate component
Solution Approach 1:
The patent applies different optical properties to different regions of the window member. The transmission area is made transparent to optimize image transmission, while the bezel area is given a different appearance (such as a colored or opaque coating) to achieve aesthetic design. This local differentiation allows each area to fulfill its specific function while maintaining overall visual integration.
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 solution enables a visually appealing bezel area integration without step differences, enhancing the aesthetic design and preventing damage during manufacturing, while ensuring secure coupling with other elements.
Implementation Method 1
a base member in which a plurality of air gaps are defined in an area of the base member corresponding to the bezel area; and a color member in the air gaps to define the color of the bezel area
Implementation Method 2
The particles may include pigments, dyes, or mixed particles of the pigments and the dyes, each of which has the color of the bezel area
Implementation Method 3
Each of the air gaps may have an average cross-sectional size equal to or greater than about 10 nm and equal to or smaller than about 1000 nm
