Transparent and Reflective Mold Bezel Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display apparatuses face challenges in reducing the thickness of the bezel, which is visually recognized by users, as the width of the non-display area (bezel) is minimized, and existing solutions fail to effectively prevent dark portions from occurring, affecting the aesthetic and functional aspects of the display.
Innovation Solution
A display apparatus design incorporating a transparent mold that supports the display module and overlaps the non-display area, combined with a reflective mold having higher light reflectance than the transparent mold, to prevent light leakage and enhance light distribution, thereby reducing the perceived bezel thickness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the width of the non-display area (bezel) is reduced, then the aesthetic appeal and perceived modernity of the display apparatus is improved, but the area available for coupling constituents and the structural stability is reduced
Solution Approach 1:
The patent employs a composite structure combining a transparent mold (first mold) and a reflective mold (second mold) to create a hybrid support system. The transparent mold provides structural support while allowing light transmission, and the reflective mold provides additional support and light reflection, together compensating for the reduced structural area caused by the minimized bezel width.
Solution Approach 2:
The transparent mold acts as an intermediary element between the display module and the reflective mold, providing both mechanical support and optical functionality. This intermediary structure allows the system to maintain structural integrity with reduced bezel width by distributing loads through multiple components rather than relying solely on the bezel area.
2Shape
If the width of the non-display area (bezel) is reduced, then the visual aesthetic is improved, but the uniformity of light distribution in the edge display area is worsened, causing dark portions
Solution Approach 1:
The transparent mold serves as an optical intermediary that allows light to pass through to the edge display area while the reflective mold behind it reflects light forward. This dual-mold intermediary system compensates for the reduced light distribution area caused by the minimized bezel, ensuring uniform illumination without dark portions.
Solution Approach 2:
The reflective mold utilizes light reflection properties (optical property change) to redirect light into the edge display area. By changing the optical path of light through reflection, the system compensates for the reduced bezel width and maintains uniform light distribution across the display surface.
3Illumination intensity
If a reflective mold with high light reflectance is introduced, then light distribution uniformity is improved, but the device complexity increases
Solution Approach 1:
The patent merges the support function and the light reflection function into a single integrated reflective mold structure. The reflective mold simultaneously provides mechanical support for the transparent mold and performs light reflection to ensure uniform distribution, combining multiple functions to reduce overall device complexity.
Solution Approach 2:
The reflective mold is designed to perform multiple functions: it supports the transparent mold structurally and simultaneously reflects light to improve illumination uniformity. This multi-functional design reduces the need for separate components, thereby managing device complexity while achieving improved light distribution.

Function Achieved in This Case
The solution effectively reduces the thickness of the visually recognized bezel by ensuring consistent light distribution across the display area, improving the aesthetic appeal and functionality of the display apparatus.
Implementation Method 1
