Optical Structure for Large Area Display in Electronic Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large area displays face limitations in compactness and manufacturing cost due to the need for improved mounting structures and additional pixels in the bezel area, which can compromise the slimness and aesthetics of electronic devices.
Innovation Solution
An optical structure is implemented within the electronic device to generate ambient light around the active display area, making it appear larger and enhancing the viewing experience while allowing for a more compact design by hiding interconnection wires and components in a non-active area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the active display area is expanded to create a large area display, then the visual impact and viewing experience are improved, but the device complexity and manufacturing cost increase due to additional pixels and mounting structures required in the bezel area
Solution Approach 1:
The patent extracts the light-guiding function from the traditional bezel area mounting structures and relocates it to an optical film layer. This separates the display expansion function from the complex mounting infrastructure, allowing the active area to appear larger without proportionally increasing structural complexity.
Solution Approach 2:
An optical film is introduced as an intermediary element between the display pixels and the viewer. This film mediates the light distribution to create the effect of an expanded active area without requiring physical expansion of the pixel array or complex bezel mounting structures.
2Area of stationary object
If additional pixels and mounting structures are added to support a large area display, then the display quality is improved, but the device thickness and compactness deteriorate
Solution Approach 1:
The patent replaces mechanical mounting structures (bezel frameworks, wire harnesses) with an optical film-based solution. This substitution eliminates the need for thick structural support elements, maintaining device slimness while achieving the large area display effect through optical manipulation rather than mechanical expansion.
3Adaptability or versatility
If traditional mounting structures are used in the bezel area, then interconnection wires and components can be accommodated, but the design aesthetics and compactness are compromised
Solution Approach 1:
The patent moves the light-guiding function from the lateral bezel dimension to the optical film layer dimension. This dimensional shift allows component accommodation and light distribution functions to coexist without compromising the sleek, minimalist aesthetic of the device front surface.
