Autostereoscopic Display View Shifting for Compact 3D Lenses
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Glassless display apparatuses face challenges in maintaining an optimal viewing distance and reducing the distance between the display panel and the lenticular lens, which affects the stereoscopic image quality if the distance is not correctly optimized.
Innovation Solution
A display apparatus and method that utilize a visual field divider and a controller to adjust the position and pixel values of images on a display panel, ensuring that the second view image is shifted inversely proportional to the distance between the display panel and the visual field divider, allowing for sequential arrangement and mixing of pixel values to maintain a 63 mm distance between view images for a 3D effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of stationary object
If the distance between the display panel and the lenticular lens is reduced, then the weight and manufacturing cost are reduced, but the viewing distance cannot be maintained at the optimal reference distance of 3m
Solution Approach 1:
The patent changes the parameter of image position by shifting the second view image based on the distance between the display panel and the lenticular lens. The controller adjusts the position of the second view image in the second image frame according to this distance parameter, allowing the system to maintain optimal viewing conditions even when the physical distance between components is reduced.
2Ease of manufacture
If the distance between the display panel and the lenticular lens is reduced, then the manufacturing cost is reduced, but the stereoscopic image quality deteriorates
Solution Approach 1:
The patent changes the parameter of image position by shifting the second view image based on the distance between the display panel and the lenticular lens. The controller adjusts the position of the second view image in the second image frame according to this distance parameter, allowing the system to maintain optimal viewing conditions even when the physical distance between components is reduced.
3Weight of stationary object
If glass material is removed to reduce weight and cost, then the device becomes more compact, but the distance optimization between display panel and lenticular lens becomes more critical
Solution Approach 1:
The patent replaces the mechanical/optical system that relies on fixed physical distances with a digital processing system. The controller dynamically adjusts the position of the second view image through digital rendering, substituting the need for precise mechanical spacing with software-based position control. This allows flexibility in component placement while maintaining image quality.

AI summary
An autostereoscopic multi-view display apparatus is provided. The display apparatus (100) includes: a display panel (110) configured to include a plurality of pixels including a plurality of sub pixels and to display an image frame; a visual field divider (slanted lenticular lens or parallax barrier) configured to be disposed on a front surface of the display panel; and a controller configured to render and to display a first image frame (20) composed of half of the views (view 1, view 3 ...) and a second image frame (40) composed of the other half of the views (view 2, view 4 ...). Each subpixel (10) corresponds to a mix of different views and the distribution of the views over the subpixels is based on a distance between the display panel and the visual field divider and is shifted between the first image frame (40) and the second image frame (40).
