Display Module Bearing Structure for Wide Viewing Angle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices do not consider the view angle, resulting in a limited viewing experience, especially in scenarios where the display is viewed from various angles, such as in vehicles or outdoor environments.
Innovation Solution
A display module comprising a backplane, a middle frame, a backlight module, and a display panel, where the backlight module and display panel are laminated on the backplane, with a bearing structure extending towards the center of the backlight module, and the view angle is optimized to be greater than or equal to 45°, enhancing visibility from different angles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display module uses a conventional structure without view angle optimization, then the structure is simple and easy to manufacture, but the viewing angle is limited and visibility from various angles is poor
Solution Approach 1:
The patent applies asymmetry by designing the bearing structure with different extension lengths in different directions. The bearing structure extends towards the center of the backlight module with varying lengths, creating an asymmetric configuration that optimizes light distribution and achieves a viewing angle of ≥45° in multiple directions without requiring complex additional components
Solution Approach 2:
The patent utilizes the spatial dimension by extending the bearing structure in specific directions towards the center of the backlight module. This dimensional arrangement of the bearing structure modifies the light path and viewing geometry, achieving enhanced view angles through spatial configuration rather than adding complex optical elements
2Adaptability or versatility
If the bearing structure is extended further towards the center to improve view angle, then the viewing angle increases, but the distance between the display panel and backlight module increases, potentially affecting light efficiency
Solution Approach 1:
The patent applies local quality by configuring the bearing structure with different extension lengths in different regions/directions. Rather than uniformly extending the bearing structure, it is extended selectively towards the center of the backlight module in specific directions, optimizing local light distribution to achieve ≥45° viewing angles while maintaining overall light efficiency
Solution Approach 2:
The patent utilizes parameter changes by adjusting the extension length and directional orientation of the bearing structure. By modifying these geometric parameters of the bearing structure, the patent optimizes the balance between achieving enhanced viewing angles and maintaining efficient light transmission from the backlight module to the display panel
