Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Auto-stereoscopic 3D display technology faces a challenge in reducing resolution when increasing the viewing range, leading to degraded image quality.
Innovation Solution
A display apparatus comprising a 3D display, an enhance display, and a mirror panel, controlled by a processor, which generates multiple image views and uses a virtual image to enhance resolution and prevent moiré effects, allowing conversion between 3D and 2D modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the viewing range is increased in auto-stereoscopic 3D display, then more viewers can view the 3D image simultaneously, but the resolution is reduced and image quality is degraded
Solution Approach 1:
A transparent display is introduced as an intermediary layer between the 3D display and the viewer. This transparent display shows a virtual image that corresponds to the 3D image, thereby improving resolution and preventing moiré effects without reducing the viewing range of the auto-stereoscopic 3D display.
2Manufacturing precision
If a transparent display is used to improve resolution, then image quality is enhanced, but luminance is reduced due to light blocking
Solution Approach 1:
The transparent display and the 3D display are controlled to operate in alternating periods. During the time when the 3D display shows the 3D image, the transparent display shows the virtual image. This periodic operation allows the transparent display to enhance resolution without continuously blocking light, thereby maintaining luminance.
3Manufacturing precision
If the transparent display operates continuously to maintain high resolution, then image quality is improved, but power consumption increases
Solution Approach 1:
The transparent display operates periodically rather than continuously, alternating its operation with the 3D display. This periodic operation maintains the high resolution benefit while significantly reducing power consumption by keeping the transparent display off during periods when the 3D display is active.

AI summary
A display apparatus includes a three dimensional (3D) display including a display panel, and a visual field separator provided on a front surface of the display panel, an enhance display provided at a first angle with respect to the 3D display, a mirror panel provided at a second angle with respect to the 3D display and provided between the 3D display and the enhance display, and at least one processor configured to operate in a 3D image provision mode and operate a two dimensional (2D) image provision mode. The at least one processor is configured to, in the 3D image provision mode, display an input image on the enhance display, provide a virtual image at a position in front of the front surface of the 3D display, and display a multiview image corresponding to the input image on the 3D display. The at least one processor is configured to, in the 2D image provision mode, display the input image on the enhance display, provide the virtual image at a position in front of the front surface of the 3D display, and turn off the 3D display.
