Problems solved by technology

[0003] The barrier-type naked-eye stereoscopic display technology requires that the stereoscopic image display layer be precisely aligned with the barrier, and the size error should be controlled to be less than the sub-pixel level. When the image moves to the front of the display screen, it is difficult to precisely locate it, so that the content of the advertising drawing cannot be displayed accurately and clearly

Embodiment 1

[0019] refer to Figure 1-5 , a precise display device for a static naked-eye three-dimensional advertising screen, comprising an outer screen 1, a grating detector 101, and an advertising screen protective case 3, the rear wall of the outer screen 1 is attached with a ring-shaped movable belt 2, and the movable belt 2 is far away from the The side wall of the outer screen 1 is fixedly connected with a plurality of advertising drawings 202, and the upper and lower ends of the movable belt 2 away from the side wall of the outer screen 1 are provided with a plurality of positioning holes 201, and the advertising drawings 202 are arranged in the upper and lower rows of positioning holes 201 Between, the inner walls of a plurality of positioning holes 201 are fixedly equipped with signal gratings 203, the parallel slits of each signal grating 203 have different sizes, and the center surrounded by the movable belt 2 is provided with a backlight plate 7, and the backlight plate 7 ser...

Embodiment 2

[0022] refer to figure 1 , a precise display device for a static naked-eye three-dimensional advertising screen, which is basically the same as Embodiment 1, and furthermore, four movable belt positioning columns 6 are arranged inside the advertising screen protective shell 3, and the four movable belt positioning columns 6 are divided into Two groups, each group of two are fixedly installed on the inner wall of the advertising screen protective shell 3 respectively, and the two groups of movable belt positioning columns 6 are arranged symmetrically, the movable belt positioning columns 6 have played a role in positioning the movable belt 2, and the movable belt 2 has been avoided. Slippage occurs during cycling.

Embodiment 3

[0024] refer to figure 1 and image 3 , a precise display device for a static naked-eye three-dimensional advertising screen, which is basically the same as Embodiment 1, and furthermore, the backlight 7 is arranged in parallel with the outer screen 1, which improves the clarity of the optical signal generated by each signal grating 203, Moreover, dark spots appearing in the external screen 1 are avoided, and the graphics display effect in the external screen 1 is improved.

[0025] Working principle: the backlight 7 provides a light source to transmit light to the signal grating 203, after superimposing the gratings with different sizes of parallel slits, the signal gratings 203 with different sizes of parallel slits are generated, and each signal grating The arrangement of the gratings of 203 is different. After the light passes through the parallel slits of different signal gratings 203, different patterns of light spots are generated. The light spots are optical signals, ...

Abstract

The invention discloses a precise display device for a static naked-eye three-dimensional advertising screen, which belongs to the field of three-dimensional display devices. The ring-shaped movable belt is fixedly connected with a plurality of advertisement drawings on the side wall of the movable belt away from the outer screen. By setting multiple positioning holes on the upper and lower sides of the advertising drawing, inside each positioning hole is a staggered arrangement of different signal gratings. There are light sources and multiple grating detectors on both sides of the three-dimensional advertising drawing, and the grating detectors receive specific optical signals. Finally, the stepping motor stops running and the electric push rod fixes the drawing on the display screen. When the grating detector does not match the optical signal, the stepping motor continues to work and fine-tune the position of the advertising drawing so that the advertising drawing is in line with the barrier. Precise alignment, so that the contents of the advertising drawings can be accurately and clearly displayed on the outer screen.

Description

technical field [0001] The invention relates to the field of three-dimensional display devices, in particular to a precise display device for a static naked-eye three-dimensional advertising screen. Background technique [0002] The static naked-eye three-dimensional advertising screen is an advertising screen that displays the advertising content through the barrier-type naked-eye three-dimensional display technology. The barrier-type naked-eye three-dimensional display technology requires multiple viewpoints to be sorted into three-dimensional images according to the barrier parameters. Alignment enables the barrier to block the interfering image and allow the image of a specific viewpoint to enter the eyes of the person, thereby making the advertisement have a naked-eye three-dimensional effect, making the advertisement content vivid and improving the advertising effect of the advertisement. [0003] The barrier-type naked-eye stereoscopic display technology requires that...
