Flexible Display Structure for Hidden Module Light Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face challenges in incorporating modules such as cameras and sensors without increasing the size of the bezel part, which leads to visibility issues and potential interference with light sensitivity.
Innovation Solution
The display device incorporates a module within the display area by using a back plate with an opening and a flexible substrate with holes, along with light-transmitting areas in the thin-film transistor layer, allowing light to reach the module without increasing the bezel size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If modules such as cameras and sensors are disposed outside the display area, then they can be provided with the display device, but the bezel part size increases
Solution Approach 1:
The patent moves the module from the traditional lateral placement (outside display area) to a vertical integration within the display area by creating openings in the back plate and flexible substrate. This dimensional repositioning allows the module to be housed within the existing display footprint, eliminating bezel expansion while maintaining module functionality.
Solution Approach 2:
The module is nested within the display structure by placing it inside openings created in the back plate and flexible substrate. The module becomes embedded within the display assembly layers (back plate opening → flexible substrate opening → TFW layer → display elements), allowing compact integration without external protrusion.
2Adaptability or versatility
If modules are disposed outside the display area, then they can be provided with the display device, but the module becomes visible externally
Solution Approach 1:
The module is nested within multiple layers of the display structure including the back plate opening, flexible substrate opening, and TFW layer. This multi-layer nesting conceals the module from external view while maintaining its functional position within the display assembly.
Solution Approach 2:
The flexible substrate with its opening and the TFW layer act as thin film structures that cover and conceal the module while allowing light transmission. These flexible layers provide optical transparency or translucency, hiding the module from view while maintaining display functionality.
3Adaptability or versatility
If modules are disposed outside the display area, then they can be provided with the display device, but light sensitivity is compromised
Solution Approach 1:
The TFW layer incorporates light-transmitting areas with optimized optical properties that allow maximum light transmission to the module while maintaining display performance. The material composition and structural design of the TFW layer are optimized to minimize light absorption and maximize illumination reach to the embedded module.
Solution Approach 2:
The TFW layer is designed with localized light-transmitting areas positioned directly over the module opening, creating regions of high optical transmission where needed. This local optimization ensures that light reaches the module effectively without compromising the overall display quality in other areas.
