Under-Screen Camera Display Layout for Higher Screen-to-Body Ratio
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Front-facing cameras pose a barrier to achieving high screen-to-body ratios in display devices, as designs such as camera area reduction, grooves, or holes affect aesthetics and require additional mechanical structures that risk damage.
Innovation Solution
An under-screen camera display screen with a display area and non-display area, featuring a bending and wiring area where pixel circuits are disposed to drive light-emitting devices, allowing the camera area to function as both a display and a light-transmitter, increasing the screen-to-body ratio by minimizing the non-display area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If front-facing camera is disposed on the display screen, then camera functionality is achieved, but screen-to-body ratio is reduced
Solution Approach 1:
The patent merges the camera area with the display area by implementing an under-screen camera design where the camera and display share the same physical space. The display screen is disposed on the light-receiving side of the camera, allowing both functions to coexist in the same region, thereby achieving camera functionality without sacrificing screen-to-body ratio.
Solution Approach 2:
The display screen serves multiple functions: it acts as both a display device and a protective cover for the under-screen camera. The same physical structure (display screen) fulfills both display and camera protection roles, eliminating the need for separate mechanical structures and maximizing screen-to-body ratio.
2Reliability
If grooves or holes are dug for camera placement, then camera functionality is achieved, but aesthetics are degraded
Solution Approach 1:
The camera and display are merged into a single integrated structure where the display screen is disposed directly on the light-receiving side of the camera. This eliminates the need for grooves or holes, maintaining a smooth, aesthetic surface while achieving camera functionality.
3Reliability
If lifting camera mechanism is added, then camera functionality is achieved, but device complexity and damage risk increase
Solution Approach 1:
The patent extracts and eliminates the lifting camera mechanism entirely by adopting a static under-screen camera design. The camera is fixed beneath the display screen without any moving parts, removing the complexity and damage risk associated with mechanical lifting structures while maintaining camera functionality.
Solution Approach 2:
The display screen serves as both the display interface and the protective cover for the under-screen camera, eliminating the need for separate mechanical protection structures. This multi-functional design reduces overall device complexity while maintaining camera functionality.
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
The under-screen camera display screen enhances light transmittance and maintains camera functionality while improving the screen-to-body ratio by optimizing the layout of pixel circuits and wiring areas, enabling dual functions of light-transmission and display.
Implementation Method 1
After bending the bending area, the wiring area and at least a part of the bending area are attached to a non-display side of the under-screen camera display screen
Implementation Method 2
a first pixel circuit that is configured to drive a light-emitting device corresponding to the under-screen camera area to emit light

AI summary
An under-screen camera display screen includes a display area and a non-display area. The display area includes an under-screen camera area. The non-display area that is located on a side of the display area and close to the under-screen camera area includes a bending area and a wiring area, and the wiring area is located on a side of the bending area away from the display area. After bending the bending area, the wiring area and at least a part of the bending area are attached to a non-display side of the under-screen camera display screen. A first pixel circuit that drives the light-emitting device corresponding to the under-screen camera area to emit light is disposed in the wiring area of the non-display area. A display device is also provided.
