Multi-viewpoint Grating for Dual-View Stereoscopic Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display devices cannot achieve dual-view and stereoscopic displays simultaneously.
Innovation Solution
A display device comprising a first panel with multiple rows of sub-pixels and a second transparent panel, both guided by a multi-viewpoint grating that directs light to form multiple fields of view, allowing for dual-view and stereoscopic image visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple panels and grating are used to achieve multi-view and stereoscopic display, then both display modes are visible, but the device structure becomes more complex
Solution Approach 1:
The grating structure serves multiple functions simultaneously: it directs light to create multiple fields of view for dual-view display, while also maintaining the spatial configuration needed for stereoscopic perception. The transparent panel similarly contributes to both the optical path for multi-view and the depth structure for stereoscopic effects, reducing the need for separate dedicated components.
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 both multi-view and naked-eye stereoscopic displays, meeting user requirements for dual-view and stereoscopic capabilities.
Implementation Method 1
a multi-viewpoint grating which guides the light emitted from the plurality of rows of sub-pixels in respective first display groups in the first panel to the respective plurality of rows of sub-pixels in the second display groups on the second panel

AI summary
A display apparatus comprises a first panel (100) and a second panel (200) disposed in a spaced manner with the first panel (100). The first panel (100) comprises multiple first display groups and each first display group comprises multiple columns of sub pixels. The second panel (200) is a transparent panel and comprises multiple second display groups, and each second display group comprises multiple columns of sub pixels. Sub pixels in the first display groups are in a one-to-one correspondence with sub pixels in the second display groups. The display apparatus also comprises a multi-vision raster (300). The multi-vision raster can guide light sent by multiple columns of sub pixels in the first display groups on the first panel (100) to multiple columns of sub pixels of corresponding second display groups on the second panel (200) in a one-to-one correspondence manner, so that multiple vision fields are formed on a light emission surface of the second panel (200) and in each vision field, a three-dimensional image can be seen and the number of the vision fields is the same as the number of the columns of the sub pixels in the first display groups. When multiple users use the same display apparatus, the multiple users can see different three-dimension images in multiple different vision fields.
