Light-Transmitting Display Panel for Camera Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display panels in electronic devices, such as mobile terminals, lack light transmission capabilities, which limits the display area and screen-to-body ratio due to the need for separate placement of light-sensitive devices like cameras.
Innovation Solution
A display panel design that incorporates light-transmitting regions, allowing both light transmission and light emitting display functions, enabling flexible placement of light-sensitive devices within the display panel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a through hole is provided in the display panel for camera operation, then the light sensitive device can operate properly, but the display area is limited and screen-to-body ratio is reduced
Solution Approach 1:
The display panel integrates multiple functions into a single structure: it provides both display functionality and light transmission for the camera. The display panel includes a light-transmitting region that allows the camera to operate without requiring a separate through-hole, thereby eliminating the need to sacrifice display area while maintaining camera functionality.
Solution Approach 2:
The patent merges the camera aperture function with the display panel structure by creating a light-transmitting region within the display panel itself. This combines the previously separate functions of display and camera light reception into a unified structure, allowing the camera to be positioned behind the display without compromising either function.
2Reliability
If the display panel and photosensitive device are disposed separately, then each component can function independently, but the screen-to-body ratio is reduced and display area is limited
Solution Approach 1:
The patent merges the photosensitive device with the display panel structure by positioning the camera behind the light-transmitting region of the display panel. This integration allows both components to maintain their independent functionality while occupying a unified spatial arrangement, thereby increasing the screen-to-body ratio without compromising component independence.
Solution Approach 2:
The patent transitions from a planar arrangement where the camera and display are separate to a three-dimensional arrangement where the camera is positioned behind the display panel. This dimensional change allows the light-sensitive device to receive light through the display panel from the front, enabling integration without compromising functional independence.
