Transparent Display Structure for Camera Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The integration of an image collection device in mobile terminals for photographing functions compromises the aesthetics and reduces the display area ratio, as it requires a hole in the front, which affects the layout efficiency of display devices.
Innovation Solution
A display structure with a transparent first area for the image collection device, where the organic light emitting diodes are placed, and the driving circuits are positioned outside this area, allowing for a higher display area ratio and improved aesthetics by maintaining transparency and efficient wiring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a hole is opened in the front of the mobile terminal for installing the image collection device, then the photographing function is implemented, but the aesthetics and display area ratio are reduced
Solution Approach 1:
The patent extracts the driving circuit from the light emission area and places it in the non-light-emitting area. This separation allows the light emission area to be fully utilized for display purposes while the extracted driving circuit occupies the previously wasted non-emitting space, thereby increasing the display area ratio without compromising the photographing function.
Solution Approach 2:
The patent utilizes the non-light-emitting area (a different spatial dimension/zone within the display structure) to accommodate the driving circuit. By transitioning the driving circuit placement from the light emission plane to the non-emission plane, the display area is maximized while still providing space for necessary circuitry.
2Adaptability or versatility
If a hole is opened in the front of the mobile terminal for installing the image collection device, then the photographing function is implemented, but the aesthetics are affected
Solution Approach 1:
The driving circuit is extracted from the light emission area and relocated to the non-light-emitting area, eliminating the need for holes or openings in the front display. This extraction allows the front surface to maintain its aesthetic integrity while still accommodating the image collection device and providing space for driving circuits elsewhere in the structure.
3Ease of operation
If the driving circuit is formed in the circuit formation area (annular area) and organic elements are formed in the light emission area, then the display function is achieved, but the layout efficiency is reduced
Solution Approach 1:
The patent merges the driving circuit and organic light-emitting elements into a single integrated display structure where the driving circuit is positioned in the non-light-emitting area and the organic elements are positioned in the light emission area. This unified integration eliminates the need for separate circuit formation areas and improves layout efficiency while maintaining display functionality.
