Problems solved by technology

[0004] Cylindrical lens type and grating type are the two commonly used implementation methods for naked-eye stereoscopic displays. However, cylindrical lens is a low-light device, which is complicated in process and high in production cost. Once the production is completed, the lens parameters are not easy to change. Compared with the conversion between three-dimensional and three-dimensional, grating autostereoscopic display has many advantages such as easy production, outstanding three-dim...

Embodiment 1

[0032] Such asfigure 1 As shown, the display is OLED, and the display content is that the odd and even pixel columns are the patterns of the corresponding pixel columns of the left and right eye patterns respectively. The material of the grating substrate is PU, and the slit grating is composed of a mixed system of PI and pseudogem-bisDPI[2.2]PC. The mass ratio of pseudogem-bisDPI[2.2]PC to PI is 1:100. The display device realizes the display of 3D scene after being irradiated by ultraviolet light for 30ms at ambient temperature.

Embodiment 2

[0034] Such as figure 1 As shown, the display is OLED, and the display content is that the odd and even pixel columns are the patterns of the corresponding pixel columns of the left and right eye patterns respectively. The material of the grating substrate is PI, and the slit grating is composed of a mixed system of PU and pseudogem-bisDPI[2.2]PC. The mass ratio of pseudogem-bisDPI[2.2] PC to PU is 1:50. The display device realizes the display of 3D scenes after being irradiated by ultraviolet light for 25ms at ambient temperature.

Embodiment 3

[0036] Such as figure 1 As shown, the display is an LCD, and the display content is that the odd and even pixel columns are the patterns of the corresponding pixel columns of the left and right eye patterns, the grating substrate material is PMMA, and the slit grating is composed of a mixed system of PAA and pseudogem-bisDPI[2.2]PC. The mass ratio of pseudogem-bisDPI[2.2]PC to PAA is 1:20. The display device realizes the display of 3D scene after being irradiated by ultraviolet light for 30ms at ambient temperature.

Abstract

The invention discloses an optically controlled grating type free and stereo display device which comprises a display and a grating plate, wherein the grating plate is adhered to the display; the center line of the grating plate is aligned with the center line of a display screen; and the content displayed by the display is a synthetized image which is preprocessed and has binocular parallax. Theoptically controlled grating type free and stereo display device is characterized in that the grating plate is composed of photochromic grids and transparent grid arranged at intervals; the photochromic grids are in a transparent state without the ultraviolet irradiation so as to realize two-dimension display for the display, and is deep blue under the ultraviolet irradiation so as to realize three-dimension display. The optically controlled grating type free and stereo display device has the advantage of simple structure, is convenient to use, and has a good three-dimensional effect, and thecontent of the types for the information display devcie is enriched.

Description

technical field [0001] The invention relates to the technical field of stereoscopic display devices, in particular to an optically controlled grating free stereoscopic display device and a preparation method thereof. Background technique [0002] With the continuous development of modern science and technology, people's requirements for display technology are getting higher and higher. Among them, 3D stereoscopic display technology has become more and more popular in recent years because of its "realism" and "interactivity". [0003] There are two mainstream trends for realizing 3D display today: stereoscopic display that requires wearing auxiliary glasses and naked-eye stereoscopic display that does not need to wear any auxiliary glasses. Obviously, the naked-eye 3D display is more comfortable and present than the 3D display with auxiliary glasses. [0004] Cylindrical lens type and grating type are the two commonly used implementation methods for naked-eye stereoscopic di...
