Under-Screen Camera Display Panel Layout for Light Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In display panels with under-screen-camera structures, it is challenging to simultaneously achieve high light transmission and display resolution in the transparent display area corresponding to the camera.
Innovation Solution
The display panel incorporates a first display area with pixel units, a second display area capable of transmitting light with light-emitting device units, and a pixel auxiliary area with light-emitting driving units. The light-emitting driving units are configured to drive the connected light-emitting device units to emit light, allowing for improved light transmission and display resolution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the transparent display area uses a high density of connecting wires to achieve high display resolution, then the display resolution is improved, but the light transmittance deteriorates
Solution Approach 1:
The patent moves the light-emitting driving units from the transparent display area to the non-transparent first display area, utilizing the vertical dimension and spatial reorganization. This dimensional transition allows the connecting wires to be routed through the non-transparent area, freeing the transparent area for optimal light transmission while maintaining high resolution through the light-emitting device units.
Solution Approach 2:
The patent extracts the light-emitting driving units from the transparent display area and relocates them to the first display area. This separation removes the harmful factor (driving units and their connecting wires) from the transparent area, allowing it to focus solely on light transmission and display function, thereby resolving the contradiction between resolution and transmittance.
2Manufacturing precision
If the transparent display area is enlarged to accommodate more connecting wires for higher resolution, then the display resolution is improved, but the area available for light transmission deteriorates
Solution Approach 1:
The patent utilizes the spatial dimension by relocating driving units to the first display area, effectively creating a three-dimensional solution to a two-dimensional problem. This allows the transparent display area to maintain its full area for light transmission while achieving high resolution through the light-emitting device units controlled by the relocated driving units.
Solution Approach 2:
The patent segments the display panel into distinct functional areas: the first display area for housing driving units and non-transparent display, and the second transparent display area for light transmission and camera integration. This segmentation allows each area to optimize its specific function without compromise.
3Manufacturing precision
If the density of light-emitting device units is increased to improve display resolution in the transparent area, then the display resolution is improved, but the light transmittance deteriorates
Solution Approach 1:
The patent applies different qualities to different areas: the light-emitting device units in the transparent display area are designed with high emission efficiency and appropriate density to achieve high resolution, while the connecting wires and driving units are relocated to the non-transparent first display area. This local differentiation allows the transparent area to simultaneously achieve high resolution and maintain light transmittance.
