Problems solved by technology

This solution requires too high accuracy in the moving distance, not only requires moving in the horizontal direction, but also moves outward for a certain distance in the vertical direction, and can only realize 2D / 3D display switching, and cannot solve the crosstalk problem of the visual zone
In addition, 2D / 3D display switching can also be achieved by adding a layer of liquid crystal layer to the original convex lens and controlling the liquid crystal layer to form convex lenses with different orientations. Limited by current technology, the curvature of the liquid crystal convex lens cannot reach the size of ordinary convex lenses, making 3D The three-dimensional effect is weakened, and only 2D / 3D display switching can be realized without solving the crosstalk problem of the viewing zone

Abstract

The invention discloses a two-dimensional / three-dimensional switchable display and a method of controlling thereof. The display comprises a display device, and a first lenticulation layer, a second lenticulation layer, and a third lenticulation layer disposed in front of the display device, and a control unit. Divergent light emitted by a same point light source of the display device forms parallel light, converging light, and parallel light in sequence. The control unit controls the third lenticulation layer to move in a straight line along an optical axis thereof. When a front-side focus of the third lenticulation layer is overlapped with a front-side focus of the second lenticulation layer, a three-dimensional image is formed. When the front-side focus of the third lenticulation layer is not overlapped with the front-side focus of the second lenticulation layer, a two-dimensional image is formed. The two-dimensional / three-dimensional display is convenient to switch. In two-dimensional display, no resolution loss exists, and in three-dimensional display, visual area width reduces obviously and crosstalk is reduced, so that three-dimensional sensor is better, and display quality of the display is effectively improved.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a two-dimensional / three-dimensional switchable display. Background technique [0002] At present, autostereoscopic display technology is developing rapidly under the active promotion of major manufacturers and the stimulation of increasing customer demand. Autostereoscopic display equipment allows people to get rid of the shackles of glasses in traditional stereoscopic display, allowing people to easily display at any time and anywhere. Feel free to experience the stereoscopic display effect of images or videos. At present, the mainstream method of autostereoscopic display is lens raster autostereoscopic display, which uses the refraction effect of the lens on the outgoing light to separate the light from different viewpoints, and then enters the left and right eyes of the person respectively, thereby achieving the effect of stereoscopic display. For details, plea...
