Eye Tracking Display System for Coplanar 3D Image Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In scenarios where multiple 3D displays are tiled together to display a stereoscopic image, the viewer may perceive a bent image due to misalignment between the displays.
Innovation Solution
A display device comprising a main display, an extended display, an eye tracking circuit, and an image processing circuit that detects the viewer's eye position, divides an original image into partial images, and converts the second partial image to be displayed on the extended display in a way that appears coplanar with the main display.

Engineering Contradiction Analysis
1Area of stationary object
If multiple 3D displays are tiled together to display a stereoscopic image, then the display area is increased, but the viewer perceives a bent image due to misalignment between the displays
Solution Approach 1:
The patent changes the display parameters (pixel positions, coordinates) of the extended display based on the detected viewing position. By dynamically adjusting these parameters, the system compensates for the physical misalignment between displays, making the combined image appear flat and coplanar to the viewer despite the displays being arranged at different angles or positions
Solution Approach 2:
The patent implements a feedback mechanism where the eye tracking circuit continuously detects the viewer's eye position, and this information is fed back to the image processing circuit. The image processing circuit then adjusts the pixel positions on the extended display based on this feedback, creating a closed-loop system that maintains image flatness adaptively as the viewer moves
2Ease of operation
If the extended display is positioned at a different angle to increase viewing flexibility, then the ease of operation is improved, but the image appears bent to the viewer
Solution Approach 1:
The patent makes the display system dynamic by continuously adjusting the pixel positions on the extended display based on the viewer's eye position. This dynamic adjustment allows the system to maintain image flatness regardless of the fixed physical angle of the extended display, enabling viewing flexibility without sacrificing image quality
Solution Approach 2:
The system changes the display parameters (pixel coordinates, positions) in real-time based on the detected viewing position. This parameter adjustment compensates for the angular misalignment between displays, allowing the extended display to be positioned at flexible angles while maintaining the perception of a flat, coplanar image

AI summary
Disclosed are a display device and an operating method thereof. The display device includes an eye tracking circuit, a main display, an extended display, and an image processing circuit. By the eye tracking circuit disposed in the main display, the image processing circuit obtains a viewing position of eyes of a user. The image processing circuit divides an original image into a first partial image and a second partial image. The first partial image is adapted to be displayed on the main display, and the second partial image is adapted to be virtually displayed on an extended virtual display. The image processing circuit converts any pixel position on the extended virtual display into a corresponding pixel position on the extended display based on the viewing position, so as to convert the second partial image into a converted second partial image to be displayed on the extended display.
