Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In display panels with under-screen-camera structures, it is challenging to simultaneously achieve sufficient light transmission and high 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 higher density of connecting wires to improve display resolution, then the display resolution is improved, but the light transmittance decreases
Solution Approach 1:
The patent moves the light-emitting driving units from the transparent display area to a pixel auxiliary area located in the non-transparent region. This spatial relocation to another dimension (from the display area to the auxiliary area) allows connecting wires to be positioned outside the light transmission path, thereby maintaining high light transmittance while achieving high display resolution through sufficient wire density in the transparent area.
Solution Approach 2:
The patent extracts the light-emitting driving units and their associated connecting wires from the transparent display area and places them in the pixel auxiliary area. This separation removes the harmful elements (connecting wires) from the light transmission path while preserving the light-emitting functionality in the transparent area.
2Illumination intensity
If the transparent display area is enlarged to improve light transmission, then the light transmittance is improved, but the display resolution decreases due to trace space limitations
Solution Approach 1:
By relocating driving units to the pixel auxiliary area in a different spatial zone (non-transparent region), the patent enables the transparent display area to be enlarged without being constrained by trace space for connecting wires. The wire density can be sufficiently maintained in the transparent area while the overall light transmission is improved through larger transparent area.
3Ease of operation
If connecting wires are placed within the transparent display area to drive light-emitting devices, then the display functionality is achieved, but the light transmittance is reduced due to wire obstruction
Solution Approach 1:
The patent extracts connecting wires from the transparent display area and relocates them to the pixel auxiliary area. This separation maintains the necessary display functionality through proper electrical connections while eliminating wire obstruction from the light transmission path, thereby improving light transmittance.
4Illumination intensity
If the pixel auxiliary area is used to place light-emitting driving units, then the light transmittance of the display area is improved, but the device structure becomes more complex
Solution Approach 1:
The pixel auxiliary area, which is part of the existing display panel structure in the non-transparent region, is utilized for housing light-emitting driving units. This multi-functional use of the auxiliary area (serving both as a structural element and as a location for driving units) avoids adding separate components, thereby reducing structural complexity while improving light transmittance.
