Problems solved by technology

[0003] At present, naked-eye 3D display devices using existing solid-state gratings (including solid-state lens gratings and solid-state slit gratings, etc.), on the one hand, will cause breakpoints or jagged edges in the 2D display screen due to the light-splitting effect of the grating, such as , resulting in bad phenomena such as zigzag cutting to the displayed text, therefore, it is not suitable for 2D display; Display, the moiré phenomenon is very serious in 3D display in the vertical screen direction, or can only achieve good 3D display in the vertical screen direction, but the moiré phenomenon is very serious in the 3D display in the horizontal screen direction, and it is impossible to take into account the horizontal screen 3D display in two orientations, orientation and portrait orientation

Embodiment 1

[0077] see figure 1 As shown in the schematic diagram, the present invention provides a stereoscopic display device 10, and the stereoscopic display device 10 is compatible with a 2D display mode, a horizontal screen stereoscopic display mode and a vertical screen stereoscopic display mode. The stereoscopic display device can be any device with a display function such as a mobile phone, a Pad, a notebook computer, a display, a game audio-visual device, and the like.

[0078] The stereoscopic display device 10 includes a display screen 13 and a grating 15 opposite to the display screen 13 .

[0079] see figure 2 , in this embodiment, the display screen 13 includes a plurality of display units 131 , that is, pixel units. A plurality of display units 131 are arranged in a matrix. Preferably, the pixel density of the display screen 13 is above 300PPI.

[0080] In this embodiment, the grating 15 is set opposite to the display screen 13 and is located on the light emitting side...

Embodiment 2

[0099] The stereoscopic display device provided by Embodiment 1 will be further described in detail through a specific embodiment below. See Figure 7 , The three-dimensional display device of the present embodiment comprises from top to bottom: a glass cover plate 21, a first optical adhesive layer 22, a grating 15, a second optical adhesive layer 24, a first polarizer 25, a display screen 13, and a backlight module Group 27.

[0100] The glass cover 21 may be a tempered glass cover 21 , that is, the glass cover 21 is made of tempered glass. When the tempered glass is damaged by external force, the fragments will become honeycomb-like obtuse-angled small particles, which are not easy to cause serious harm to the human body; the impact strength of tempered glass with the same thickness is 3 to 5 times that of ordinary glass, and the bending strength is 5 times that of ordinary glass. 3 to 5 times that of glass; tempered glass has good thermal stability, and can withstand a t...

Embodiment 3

[0138] See Figure 10 , the structure of the stereoscopic display device of this embodiment is similar to that of Embodiment 2. The stereoscopic display device of this embodiment comprises from bottom to top: backlight module 35, display screen 13, optical film 33, optical glue layer 32 and glass cover 31, wherein the optical film 33 includes a second polarizer and a single-layer grating on the second polarizer (the single-layer grating is a UV-LENS lens grating), and the single-layer grating is integrally formed with the second polarizer to form the optical film33. A first polarizer (not shown) may also be arranged between the backlight module 35 and the display screen 13 .

[0139] In this embodiment, the single-layer grating includes a plurality of curved lenses arranged in parallel, wherein the bottom surface of the curved lens coincides with the upper surface of the second polarizer.

Abstract

The invention relates to the technical field of stereo display and discloses an optical grating, a stereo display device with the same and a display method. The stereo display device is compatible toa 2D display mode, a cross screen stereo display mode and a vertical screen stereo display mode, and comprises a display screen and the optical grating opposite to the display screen. The shape and the size of the optical grating match with the shape and the size of the display screen. The optical grating is a single-layer optical grating. The single-layer optical grating is a UV-lens lens opticalgrating and comprises multiple parallelly arranged optical grating units. The optical grating units are obliquely arranged related to the long edges or short edges of the display screen. The includedangle of the long edge and the corresponding short edge is between 30 degrees or 40 degrees. According to the invention, compatibility to the 2D display mode, the cross screen 3D display mode and thevertical screen 3D display mode can be achieved; the optical grating, the device and the method are advantaged in that the moire effects are low and problems of forming of breaking points or sawtooth-shaped cutting during 2D display are weakened; and display effects of each display mode can be effectively ensured.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a grating, a three-dimensional display device with the grating and a display method. Background technique [0002] The naked-eye 3D display device usually includes a display panel and a grating arranged on the display panel. When performing naked-eye 3D display, the stereoscopic image is first arranged, that is, the left-eye image and the right-eye image are arranged and displayed on the naked-eye 3D display screen according to certain rules. On the panel, at the same time, cooperate with the spectroscopic effect of the grating, send the left eye image to the user's left eye, and send the right eye image to the user's right eye, so that the user can watch 3D images. Due to objectively getting rid of the shackles of ancillary equipment such as stereo glasses, improving viewing comfort and broadening application fields, naked-eye 3D display technology can provide users wit...
