Stereoscopic Display Border Depth Error
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In large frame stereoscopic displays, the borders between panels create an error in depth of field, leading to discomfort for observers due to the inability to adjust the depth of field at these borders, as stereoscopic images cannot be generated there, resulting in a lack of embossed effect.
Innovation Solution
The method involves adding stripe segments adjacent to the borders between stereoscopic display panels, adjusting their width to match the depth of field of the adjacent images, and optionally dividing the border into portions with corresponding sub-stripe segments to create a floating frame with uniform depth of field, and adjusting the color of the stripe segments to blend with the border and image colors.

Engineering Contradiction Analysis
1Area of stationary object
If multiple stereoscopic display panels are assembled into a video wall to achieve large frame stereoscopic display, then the display area is increased, but borders between panels create depth of field errors causing observer discomfort
Solution Approach 1:
The patent introduces an intermediary element (the stripe segment) between the border and the stereoscopic image content. This stripe segment acts as a mediator that generates a floating frame effect, allowing the border area to participate in stereoscopic display and match the depth of field of adjacent images, thereby eliminating the depth of field error caused by panel borders while maintaining the large display area achieved through video wall assembly
2Shape
If borders are added between stereoscopic display panels to separate individual panels, then panel identification is improved, but the borders cannot generate stereoscopic images resulting in inconsistent depth of field
Solution Approach 1:
The patent applies local quality by making the stripe segments adjacent to the border have different properties from other areas. Specifically, the stripe segments near the border are designed to generate a floating frame effect that matches the depth of field of adjacent stereoscopic images, while other areas maintain normal stereoscopic display. This localized treatment ensures that the border area achieves both separation function and depth of field consistency

AI summary
A stereoscopic display method includes the following acts. A plurality of stereoscopic images are provided by providing a plurality of stereoscopic display panels. At least one border is disposed between two of the stereoscopic display panels adjacent to each other. At least one stripe segment is added in each of the stereoscopic images. The stripe segments are adjacent to the border, such that the stripe segments and the border form a floating frame when an observer observes the stripe segments and the border using both eyes of the observer. A width of each of the stripe segments is adjusted, such that a depth of field of the floating frame is substantially the same as a depth of field of the stereoscopic images adjacent to the floating frame.
