Transparent Display Gaze Control for Dual-Sided Image Differentiation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transparent display technologies are limited in their application scope and do not effectively utilize gaze detection to enhance communication between users on opposite sides of the display.
Innovation Solution
A transparent display apparatus with a sensor device for detecting a user's viewpoint, allowing the controller to display individually selectable images based on gaze detection, enabling images to be viewed from both sides of the display with controlled transparency states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a transparent display apparatus displays images to users on both sides, then communication between users is enabled, but the display cannot show different images to different users simultaneously
Solution Approach 1:
The display apparatus displays different images to users on opposite sides by controlling the transparency state of individual pixels or regions. The controller adjusts the transparency of pixels in the first region for the first user while maintaining different transparency states for pixels in the second region for the second user, enabling each user to see a customized image tailored to their viewing side.
2Ease of operation
If the display layer transitions between transparent and non-transparent states, then image visibility is controlled, but the ability to provide different views to different users is limited
Solution Approach 1:
The display region is divided into multiple regions (first region and second region) that can be independently controlled. The controller can set the transparency state of pixels in each region separately, allowing the first region to display an first image for the first user while the second region displays a second image for the second user, thereby achieving multi-user display flexibility.
3Extent of automation
If gaze detection is implemented, then user interaction is enhanced, but the device complexity increases
Solution Approach 1:
The sensor device automatically detects the viewpoint or gaze direction of the first user without requiring manual input. The controller uses this detection information to automatically determine which selection image the first user is viewing and subsequently controls the pixels to display the appropriate corresponding image to the second user, enabling gaze-based selection automation.
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 enhanced communication by allowing users on opposite sides of the display to see different images, expanding the use applications of transparent displays, particularly in fields like medical communication.
Implementation Method 1
a display layer arranged between the first substrate and the second substrate, and having pixels that can transition between a transparent state of transmitting background light and a non-transparent state of displaying an image

AI summary
A transparent display apparatus includes a first substrate having a first surface, a second substrate having a second surface, a display layer having pixels, a display region provided in a region where the first substrate, the second substrate, and the display layer overlap, a controller, and a sensor device for detecting a viewpoint of the first user. The controller displays a plurality of individually selectable selection images toward the first user in the display region (screen), determines a gaze image, which is the selection image gazed by the first user, from detection information of the sensor device, and controls a state of pixels so that the corresponding image based on the gaze image is displayed to the second user on an opposite side to the first user.
