Display Panel With Sideways Light Emission For Under-Screen Camera
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In display devices, the area designated for an under-screen camera cannot display or image normally due to the need to remove the device film layer.
Innovation Solution
A display panel design featuring an array substrate with a first and second anode layer, a pixel definition layer with holes, a light-emitting layer, and a cathode layer, where the light-emitting portions connect the anode layers and emit light sideways from the vacancy area, allowing normal display and imaging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the device film layer is removed to dispose an under-screen camera, then the camera can be installed, but the area cannot display or image normally
Solution Approach 1:
The anode layer is divided into a first anode layer and a second anode layer, with the second anode layer positioned in the vacancy area to provide independent electrical connection and light emission capability, enabling the camera area to function independently while maintaining display functionality
Solution Approach 2:
Light emission is redirected from vertical (through the display stack) to lateral direction (sideways from the vacancy area edge), allowing the camera area to emit light in a different spatial dimension that does not interfere with the camera's optical path while still providing visible display output
2Adaptability or versatility
If the functional film layer is removed for camera placement, then camera integration is achieved, but normal light emission and display are compromised
Solution Approach 1:
The second anode layer is pre-positioned in the vacancy area during the manufacturing process, and the light-emitting layer is configured to extend into this area, ensuring that light emission capability is established before the device is assembled and tested
Solution Approach 2:
The light emission path is changed from vertical (through the display layers) to lateral (from the edge of the vacancy area), allowing light to be emitted from a different spatial location that does not require the traditional vertical optical path through the camera area
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables normal display and imaging from the area with the under-screen camera by emitting light sideways, ensuring the area can function despite the removal of the functional film layer.
Implementation Method 1
a light-emitting layer including a plurality of light-emitting portions, wherein each of the plurality of light-emitting portions is disposed in one of the plurality of holes, and the plurality of light-emitting portions cover and electrically connect the first anode layer and the second anode layer
