no. 1 approach

[0081] Such as figure 2 As shown in FIG. 1 , it is a structural schematic diagram of the naked-eye stereoscopic display device in the first embodiment of the present invention. The naked-eye stereoscopic display device comprises: a light splitting device 21, a polarization state controller 230, a display panel 250, a backlight plate 240, a light splitting device driver 200, a polarization state controller driver 231, a display panel driver 251 and a synchronous control device, wherein

[0082] The spectroscopic device driver 200 is used to drive the spectroscopic device 21 to work;

[0083] A polarization state controller driver 231, configured to drive the polarization state controller 230 to work;

[0084] The display panel driver 251 is used to drive the display panel 250 to work;

no. 2 approach

[0129] In the example of the second embodiment of the present invention, the first liquid crystal lens grating and the second liquid crystal lens grating used by the spectroscopic device can not only adopt the double-layer liquid crystal lens grating with the same electrode structure design, but also can use a 2D / The double-layer solid-state lens grating structure with 3D switching function requires that the positions of the microlenses formed in the corresponding double-layer lenses are different, which are used to generate the light splitting effect at the first moment and the second moment respectively, so as to transmit light to the two eyes respectively. Different images, and through the combination of two time frames, the images received by each eye can achieve the display effect of full-resolution images.

[0130] In an example of the second embodiment of the present invention, the above-mentioned double-layer solid lens grating includes: a single-refraction lens and a ...

Embodiment 1

[0164] Such as Figure 15 Shown is a schematic diagram of a naked-eye stereoscopic display device in Example 1 of the second embodiment of the present invention.

[0165] The naked-eye stereoscopic display device 100 is in a non-electrically controlled state, wherein the first single-refraction convex lens 105a and the second single-refraction convex lens 105b are a single-refraction lens array. The single lens grating length of the first single refractive index convex lens 105a and the second single refractive index convex lens 105b is the same, and as Figure 15 The dotted line in the middle indicates that the lens arrays of the first single-refractive index convex lens 105a and the second single-refractive index convex lens 105b differ by half a period in arrangement. The first alignment layer 103a and the second alignment layer 103b align the liquid crystal cells 104a and 104b.

[0166] see Figure 15 , the light emitted by the display panel 101 that provides images is ...

Abstract

The invention provides an autostereoscopic display device which comprises a backlight plate, a display panel for displaying two-dimensional (2D) images or three-dimensional (3D) images, a light splitting device for transmitting provided images in 2D mode and dividing incident images into right-eye images and left-eye images in 3D mode and a polarization controller. The polarization controller is arranged between the display panel and the light splitting device, is used for rotating the vibration direction of light provided by the display panel in 2D mode at 90 degrees, and cannot change the vibration direction of the light provided by the display panel in 3D mode. Autostereoscopic display is achieved by using the light splitting device and the polarization controller, and the problem of descending of backlight utilization rate in the prior art can be avoided effectively.

Description

technical field [0001] The invention relates to the technical field of stereoscopic display, in particular to a full-resolution naked-eye stereoscopic display device. Background technique [0002] In the stereoscopic display technology, the principle of binocular parallax is used to make the user feel close to the real stereoscopic feeling. The current stereoscopic display technology is divided into two categories: glasses type and naked eye type. Generally speaking, the naked-eye stereoscopic display device has the advantages of being convenient to use and conforming to the daily viewing habits of human eyes, but the naked-eye stereoscopic display device also has its inherent defects. [0003] At present, the implementation methods of naked-eye stereoscopic display generally include parallax slit grating, micro-cylindrical lens array, and directional backlight. However, these methods all adopt the method of space division to display stereoscopic images, which will cause t...
