Display Boundary Structure Using Translucent Edge Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to reduce the visible contour between the frame region and the display region in a display apparatus, such as an electronic mirror, which affects its appearance.
Innovation Solution
The display apparatus incorporates an optical member with translucency, a transmissive member with a transmittance of 5% or more, and an electro-optical member with voltage-dependent optical characteristics, along with a housing that includes a protruding portion to cover the end portion of the electro-optical member, thereby reducing the boundary contour.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the display apparatus uses a conventional structure with clear boundaries between frame and display regions, then the internal structures are well-defined and easy to manufacture, but the contour at the boundary becomes visible and degrades appearance
Solution Approach 1:
The patent applies local quality by making the optical member translucent specifically at the boundary region between the frame and display areas. This localized translucency allows light to pass through the boundary contour, making it invisible from the front, while the rest of the structure maintains its conventional defined form for manufacturing purposes.
Solution Approach 2:
The translucent optical member acts as an intermediary element positioned at the boundary between the frame region and display region. It mediates the visual transition by allowing light transmission through the boundary contour, thereby eliminating the visible separation line without requiring fundamental changes to the overall structural design.
2Shape
If the display apparatus uses a translucent optical member to reduce boundary visibility, then the appearance is enhanced, but the internal structures become more difficult to detect and measure
Solution Approach 1:
The patent segments the optical member into different functional regions: a translucent portion at the boundary for aesthetic purposes and opaque or transparent portions in other areas for manufacturing and inspection purposes. This segmentation allows the translucent property to be localized only where needed for reducing boundary visibility.
Solution Approach 2:
The translucency is applied locally only to the boundary region of the optical member, not to the entire structure. This localized application ensures that internal structures remain visible and measurable in non-boundary areas, while the boundary contour becomes invisible from the front view.
3Shape
If the transmissive member has high transmittance to reduce contour visibility, then the boundary becomes less visible, but more light is transmitted which may affect display contrast
Solution Approach 1:
The patent applies translucency locally to the boundary region of the optical member, allowing light transmission specifically at the contour line to make it invisible. The rest of the optical member maintains its original optical properties, ensuring that display contrast and brightness are not compromised by excessive light transmission.
Solution Approach 2:
The patent uses partial action by implementing translucency only to the extent needed for boundary invisibility, rather than making the entire optical member translucent. This partial application of translucency ensures sufficient light transmission for contour elimination while avoiding excessive light transmission that would degrade display contrast.

AI summary
A display apparatus includes an optical member with translucency, a transmissive member, an electro-optical member, and a housing. The optical member includes a front surface corresponding to an observation side and a back surface lying behind the front surface. The transmissive member is provided on a peripheral edge of the back surface of the optical member. The transmissive member has a transmittance of 5% or more. The electro-optical member is provided on a side of the back surface of the optical member. The electro-optical member has optical characteristics varying with applied voltage. The housing includes a protruding portion. The protruding portion covers an end portion of the electro-optical member and protrudes toward the back surface of the optical member. An end portion of the transmissive member is located between an end portion of the optical member and the protruding portion.
