A display device, naked-eye 3D display system and virtual reality glasses

Abstract

The invention discloses a display device, a naked-eye 3D display system and virtual reality glasses, relates to the field of display technology, and solves the technical problem of low light utilization rate of the display device. The display device includes a backlight source and a polarizer disposed on the light-emitting side of the backlight source, and the display device also includes a plurality of liquid crystal screens stacked on the light-emitting side of the polarizer, and each of the liquid crystal screens includes multiple The light adjustment units included in the plurality of liquid crystal screens are arranged in a staggered manner; each light adjustment unit adjusts the light to make the light emitted by the backlight refract and shoot to the target position or undergo total reflection. . The display device is applied to naked-eye 3D display or virtual reality display.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display device, a naked-eye 3D display system and virtual display glasses. Background technique [0002] In the field of display technology, precise control of the propagation direction of the light emitted from the display device can enable more light to hit the target position (such as the human eye), thereby effectively improving the utilization rate of the light of the display device and improving the display. The display effect of the device. [0003] Exemplarily, as figure 1 As shown, the display device capable of precisely controlling the propagation direction of the light emitted by it includes a backlight 1', a polarizer 2', a first substrate 3', a liquid crystal molecular layer 4' and a second substrate 5' which are sequentially stacked. , wherein, the first substrate 3' is provided with a plurality of strip electrodes 31', and the second substrate 5' is provided w...

Problems solved by technology

[0004] The inventors of the present application found that, for the display device with the above-mentioned structure, since each light adjusting unit 6' needs to adjust the propagation direction of the light emitted by the backlight 1', so that it all shoots to the target position, that is, The refraction angles of the light emitted from each light adjustment unit 6' are different, and the refractive indices of the liquid crystal prisms equivalent to each light adjustment unit 6' are different. Therefore, the deflection states of the liquid crystal molecules corresponding to each light adjustment unit 6' are all different, thereby making The deflection state of the liquid crystal molecules located between two adjacent light adjusting units 6' is chaotic, which makes the propagation direction of the light directed to this part of the liquid crystal molecules chaotic, and cannot be directed to the target position, resulting in the low utilization rate of the light of the display device. high
