Light-Transmissive Display Panel for Unobstructed Two-Way Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing two-way communication systems and display devices with image pickup functions are either bulky, obstructive, or degrade image quality, making them unsuitable for portable applications and unable to maintain user eye focus during image display and capture.
Innovation Solution
A compact and lightweight display device with a light-transmissive display panel and an image pickup unit disposed on the back, using light-emitting elements with controlled emission by voltage or current, allowing simultaneous image display and capture without obstructing the view, achieved through a self-luminous panel design that transmits visible light and corrects for color and luminance deviations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a camera is disposed in front of the display screen to capture user images, then image pickup function is achieved, but the camera obstructs the monitor image and shades part of the display
Solution Approach 1:
The camera is moved from the front surface of the display screen to the back surface, utilizing the third dimension (depth) to resolve the spatial conflict between image capture and display functions. This allows both functions to coexist without mutual obstruction.
Solution Approach 2:
The display screen itself serves as an intermediary medium, allowing light to pass through it to reach the camera on the back surface. This transparent mediation enables the camera to capture images without blocking the display from the front.
2Adaptability or versatility
If a pinhole is formed on the display screen to allow image pickup, then simultaneous image display and capture is achieved, but the pinhole creates defects in the display image and reduces definition
Solution Approach 1:
The camera is extracted from the front surface of the display and repositioned on the back surface, eliminating the need for pinholes or openings in the display screen. This preserves the integrity and quality of the display surface.
Solution Approach 2:
The display screen acts as a transparent intermediary that allows optical signals to pass through to the camera without requiring physical openings, thereby maintaining display image quality while enabling image capture functionality.
3Ease of operation
If a special screen and projector display device are used to achieve two-way communication with eye contact, then communication quality is improved, but the device becomes large and heavy
Solution Approach 1:
The display screen serves multiple functions simultaneously: it displays images from the communication partner, allows the camera to capture the user's image through its transparency, and enables eye contact functionality. This multi-functionality eliminates the need for separate specialized components.
Solution Approach 2:
The display and image pickup functions are merged into a single integrated structure where the camera is positioned on the back of the display screen. This combination reduces the overall device complexity and weight compared to using separate projector and screen systems.

AI summary
A two-way communication device having a display device of novel structure and an image pickup device is provided. More particularly, a two-way communication system having a display device and an image pickup device is provided. The display device having an image pickup function includes an image pickup unit and a display panel in which light emitting elements which can transmit visible light at least and be controlled by voltage or current are arranged. A compact and lightweight device can be achieved without using a complicated optical system or an optical system having a long light path, whereby two parties can communicate while catching each other's eyes.
