Transparent Display Camera Module via Rear Projection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic display devices face challenges in achieving a high screen-to-body ratio while maintaining the integration and functionality of components like camera modules, as cutting grooves or drilling holes compromises aesthetics and waterproof/dustproof performance.
Innovation Solution
A display device with a primary screen featuring a transparent region, a secondary display, and an optical function processor that projects images and performs optical functions through this transparent area, allowing for a hidden camera module and maintaining the device's integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a groove or hole is cut in the display screen to accommodate the camera module, then the camera module can be integrated and external light can enter, but the aesthetics and waterproof/dustproof performance are compromised
Solution Approach 1:
The camera module is relocated from the front display surface to the rear side of the display screen, utilizing the z-dimension (depth) rather than compromising the x-y plane aesthetics. The light path is extended through the transparent display screen to reach the camera module positioned on the opposite side, thereby maintaining screen integrity while enabling camera functionality.
Solution Approach 2:
The transparent display screen serves as an intermediary element that allows light to pass through from the front surface to the camera module on the rear side. This mediator enables optical communication between the external environment and the hidden camera module without requiring physical openings in the display structure.
2Area of stationary object
If the screen-to-body ratio is increased to achieve better display effect, then the display area is maximized, but there is no space left for camera modules and other components
Solution Approach 1:
Instead of reducing display area to accommodate components on the front surface, the invention utilizes the third dimension by positioning the camera module on the rear side of the display screen. This vertical displacement allows the display screen to extend to the edges of the device body while still providing space for optical components through the transparent region.
Solution Approach 2:
The camera module is nested within the device body structure, with its optical path passing through the transparent display screen. This nesting arrangement allows the camera module to be housed within the available internal space without protruding or requiring additional external volume, thereby maintaining the maximized screen-to-body ratio.
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 a high screen-to-body ratio without compromising aesthetics or functionality, as the camera module can operate through the transparent region, maintaining the device's integration and waterproof/dustproof performance.
Implementation Method 1
the secondary display is located at a side of the primary display screen opposite to the display surface of the primary display screen, and is configured to project image light to the transparent region of the primary display screen for displaying in the transparent region
Implementation Method 2
in the first state, the first mirror is configured to reflect the image light of the secondary display to the transparent region
Implementation Method 3
in the second state, the first mirror is configured to reflect the light beams passing through the transparent region from the display side of the primary display screen to the optical function processor
Implementation Method 4
The second mirror is configured to reflect the image light of the secondary display to a reflecting surface of the first mirror in the first state, so that the image light of the secondary display is further reflected by the first mirror to the transparent region
