Embodiment 1

[0074] This embodiment provides a display device, including a display screen and at least one optical device located on the light-emitting side of the display screen, the outgoing light of the display screen is linearly polarized collimated light, and the optical device includes a plurality of mutually independent The optical unit corresponds to the pixel unit of the display screen one by one, the optical unit can refract the outgoing light of the display screen, and the optical unit passes through the pixel unit of the display screen The angle of refraction of the outgoing light rays is adjustable, and the outgoing angles of the collimated light rays emitted by adjacent optical units are different, so that the outgoing light rays of the display screen converge to two viewpoints to display a virtual image with a preset spatial depth.

[0075] In this embodiment, the outgoing light of the display screen is a linearly polarized collimated light, and the optical device includes a ...

Embodiment 2

[0102] This embodiment provides a display method, which is applied to the above-mentioned display device, and the display method includes:

[0103] Adjusting the angle at which the optical unit refracts the outgoing light of the display screen, so that the outgoing angles of the collimated light emitted by adjacent optical units are different, and the outgoing light of the display screen converges to two viewpoints to display A virtual image of spatial depth.

[0104] Further, the display method specifically includes:

[0105] Acquiring the spatial depth of the virtual image to be displayed by the display device, and determining the inclination angle of the equivalent rectangular prism corresponding to each optical unit according to the spatial depth of the virtual image to be displayed;

[0106] Divide each optical unit into m parts, and determine the difference between the refractive index of each part in each optical unit and the refractive index of the part with the small...

Embodiment 3

[0126] The display device of the present invention is further introduced below in conjunction with the accompanying drawings:

[0127] figure 2 It is a structural schematic diagram of an optical device according to an embodiment of the present invention. The optical device can refract the linearly polarized collimated light emitted from the display screen 1, so that the light beam can be accurately directed to human eyes. Wherein, the optical device includes from bottom to top: a base substrate 2 , a first electrode 5 , a liquid crystal cell 3 , a second electrode 6 and a base substrate 4 . Wherein, the display screen 1 may be an LCD display screen or an OLED display screen, but the light incident on the optical device needs to be a linearly polarized collimated light beam.

[0128] The upper surface of the base substrate 2 is provided with a first electrode 5, and the lower surface of the base substrate 4 is provided with a second electrode 6, both of the first electrode 5 ...

Abstract

The invention provides a display device and a display method thereof, which belong to the technical field of display. Wherein the display device includes a display screen and at least one optical device located on the light exit side of the display screen, the outgoing light of the display screen is linearly polarized collimated light, the optical device includes a plurality of mutually independent optical units, the The optical unit corresponds to the pixel unit of the display screen one by one, the optical unit can refract the outgoing light of the display screen, and the optical unit refracts the outgoing light passing through the pixel unit of the display screen The angle is adjustable, and the outgoing angles of the collimated light emitted by adjacent optical units are different, so that the outgoing light of the display screen converges to two viewpoints to display a virtual image with a preset spatial depth. Through the technical scheme of the invention, virtual image display with free space depth can be realized.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device and a display method thereof. Background technique [0002] In the existing virtual display device, two positive lenses are placed in front of the display screen, so that the focal length of the positive lens is greater than the distance from the display screen to the positive lens, so that the positive lens acts as a magnifying glass, and the image is enlarged and far away, so that the eyes The enlarged and far-reaching upright virtual image can be seen at the near eye and fused in the brain to produce stereoscopic vision. [0003] The disadvantages of the prior art solutions are: the two positive lenses are relatively thick, and the single lens will introduce optical aberration, so that the virtual display device will make people feel uncomfortable no matter whether it is worn or displayed on the screen, and the virtual display device The spatial dept...
