Embodiment 1

[0047] Such as Figure 1-3 As shown, the present embodiment provides a reflective 3D display device, including: a display panel 1, a human eye tracking unit, and a MEMS (rotary micro-electromechanical system) mirror 2; wherein, the display panel 1 includes multiple columns of pixels; The pixels include alternately arranged left-eye pixels L and right-eye pixels R; the left-eye pixels L are used to form left-eye images; the right-eye pixels R are used to form right-eye images; the human eye tracking unit is used to identify people Eye position information; a plurality of MEMS reflectors 2 are located on the side away from the display surface of the display panel 1, and are used to rotate according to the position information of the human eye, and adjust the light emission direction irradiated on the MEMS reflector 2, so that The light after passing through the display panel 1 enters human eyes to form a 3D display image.

[0048] Since the display panel in the display device o...

Embodiment 2

[0060] This embodiment provides a display method for a reflective 3D display device, and the reflective 3D display device is any one of the display devices in Embodiment 1. The display method specifically includes:

[0061] Controlling the left-eye pixel L in the display panel 1 to display a left-eye image, and the right-eye pixel R to display a right-eye image;

[0062] Identify the position information of the human eye through the human eye tracking unit;

[0063] According to the position information of the human eye, the MEMS mirror 2 is controlled to rotate, and the direction of light emitted on the MEMS mirror 2 is adjusted, so that the light passing through the display panel 1 enters the human eye to form a 3D display screen.

[0064] Specifically, when the reflective 3D display device in this embodiment adopts the display device in the first implementation mode in Example 1, that is, the plurality of MEMS mirrors 2 include a first MEMS mirror 21 and a second MEMS mirr...

Abstract

The invention provides a reflective 3D display device, belongs to the technical field of the display device and solves the problem that an existing 3D display device is high in power consumption and low in resolution. The reflective 3D display device provided by the invention comprises a display panel which comprises a plurality of columns of pixels, wherein the plurality of columns of pixels comprise left eye pixels and right eye pixels which are arranged alternately, the left eye pixels are used for forming a left eye image, and the right eye pixels are used for forming a right eye image; an eye tracking unit which is used for identifying position information of eyes; and an MEMS reflector which is located at the side deviating from a display surface of the display panel, is used for carrying out rotation according to the position information of the eyes and adjusting a light emitting direction irradiated on the MEMS reflector, so the light passing through the display panel is incident to the eyes to form a 3D display image.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a reflective 3D display device. Background technique [0002] Stereoscopic display, that is, 3D display technology, is mainly based on human vision to obtain two images of the same object at different angles, and project these two images into the left and right eyes of the person respectively, so that the images in the left and right eyes of the person With a certain parallax, the brain synthesizes the left-eye image and the right-eye image with parallax to produce depth perception, that is, to form a stereoscopic image display effect. [0003] Existing 3D display technologies are mainly divided into two categories: glasses-type and naked-eye-type. The glasses-type 3D display technology needs to wear special glasses, so it is not conducive to the use of portable devices. More emphasis is placed on naked-eye 3D display technology in mobile electronic products. The ...
