Abstract

The invention relates to a grating device capable of achieving 2D / 3D conversion. The grating device comprises a frame-shaped machine frame, two grating recycling guide rails, a flexible slit grating, an upper locator, a lower locator, a grating tensioning and weighing unit and a plurality of grating recycling units. The grating device enables an LED display screen to directly have the three-dimensional display function, can achieve switch display between a 2D display mode and a 3D display mode according display contents, is simple in manufacturing process and can easily achieve production and manufacturing of large LED three-dimensional displayers.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a grating device capable of realizing 2D / 3D conversion and a display including the device. Background technique [0002] Glasses-free 3D displays have become a research hotspot in the display field at this stage because they can watch 3D images without the need for viewers to wear glasses or helmets. At present, LCD displays are used to refit naked-eye stereoscopic displays, but the size is limited by the size of the LCD display itself, and it is impossible to provide a larger-sized naked-eye stereoscopic display. Sometimes there will be problems such as weak light and difficult to realize 2D / 3D mode switching. [0003] Because LED display technology has the advantages of high brightness, environmental protection and energy saving, fast response, impact resistance and stable performance, LED display screens are widely used as displays, display boards, bulletin boards, etc. in o...
