Embodiment Construction

[0035] Such as figure 2 and 3 As shown, the 2D / 3D switchable autostereoscopic display device of the present invention includes a light guide plate 10 , a first light source 40 , a second light source 50 and a reflection plate 30 . The light guide plate 10 is disposed between the reflection plate 30 and the liquid crystal display 20 , the first surface of the light guide plate 10 faces the liquid crystal display 20 , and the second surface of the light guide plate 10 faces the reflection plate 30 . The first surface of the light guide plate 10 has a plurality of phosphor powder coating areas, such as the phosphor powder coating area 11, and these phosphor powder coating areas are distributed in a periodic band shape.

[0036] The first light source 40 is disposed on one side wall of the light guide plate 10 , the second light source 50 is disposed on the other side wall of the light guide plate 10 , and the two side walls are opposite to each other. The first light source 40...

Abstract

The invention discloses a 2D/3D (two-dimensional/three-dimensional) switchable autostereoscopic display device and a 2D/3D (two-dimensional/three-dimensional) switchable autostereoscopic display method. The autostereoscopic display device comprises a light guide plate, a first light source, a second light source and a reflector plate, wherein the light guide plate is arranged between the reflector plate and a liquid crystal display screen; the first surface of the light guide plate is opposite to the liquid crystal display screen; the second surface of the light guide plate is opposite to the reflector plate; the first light source and the second light source are arranged on the lateral wall of the light guide plate; a plurality of fluorescent powder coating areas are arranged on the first surface; the fluorescent powder coating areas are periodically distributed in a strip manner; and the light emitted from the first light source displays a 2D image, and the fluorescent powder coating areas is stimulated for lighting by the light emitted by the second light source so as to display a 3D image. The autostereoscopic display device disclosed by the invention has the advantages of simple structure and better display effect of the 2D and 3D images, and can conveniently and fast switch between 2D/3D two display modes.

Description

technical field [0001] The invention relates to autostereoscopic display technology, in particular to a 2D / 3D switchable autostereoscopic display device and a method thereof. Background technique [0002] Stereoscopic display is the main type of three-dimensional display, which uses parallax to realize the depth sensitivity of human eyes. Stereoscopic display can be divided into stereoscopic display that needs to wear auxiliary glasses device and automatic stereoscopic display that does not need to wear any auxiliary glasses device. Autostereoscopic display technology can be used in military, medical, data visualization, engineering, entertainment, virtual business trade and education, and has become a research hotspot in the field of display technology in the world. [0003] The parallax projection technology separates the left and right eye images by controlling the images displayed on the LCD screen by controlling the light emitted from the light guide plate. Among them...
