Problems solved by technology

[0002] Glasses-free 3D display technology enables viewers to take off 3D glasses, which improves viewing comfort. However, ordinary glasses-free 3D display devices have the problem of viewing area flipping whether they are dual-viewpoints or multi-viewpoints. The right eye may receive the image for the right eye, and the same right eye may receive the image for the left eye, so the 3D image cannot be viewed normally, and it is easy to cause visual fatigue, which is not suitable for long-term viewing, and the resolution of the existing multi-viewpoint 3D display also varies. Therefore, it is necessary to provide a new 3D display to solve the above problems

Embodiment 1

[0015] Please refer to figure 1 Embodiment 1 of the present invention provides a multi-viewpoint LED autostereoscopic display device, which has at least two viewpoints. The display device includes an LED display screen 1 and a grating 2 arranged on the picture output side of the LED display screen 1, and may also include a computer 3. Connect with the LED display 1. Through the special design of the pixels 11 and the grating 2 of the display screen, the reversal of the viewing area can be effectively reduced and the resolution can be improved. Specifically, the pixel 11 of the LED display screen 1 is synthesized by RGB three primary color light-emitting chips, which is different from the liquid crystal display in that its RGB sub-pixels are integrated into one LED lamp bead, that is, one pixel, which cannot be divided. The pixels in this embodiment are arranged in the following manner, the pixels in the i-th row are moved by ni=mod(round(i-1)×tanθ), N) pixels than the pixels ...

Embodiment 2

[0022] As a preferred implementation manner, the grating stripes 21 in this embodiment form an angle θ with the vertical direction of the LED display 1 , θ=81°. The pixel distribution of the first row is to set V0, V1, V2 ... VN-1 cyclically from left to right, wherein, N is the number of viewpoints, and the pixels in the i-th row move ni=mod( round(i-1)×tanθ), N) pixels, round() is a rounding function, mod(round(i-1)×tanθ), N) means round(i-1)×tanθ divided by N Take the remainder, if ni is positive, it will be shifted to the right, otherwise it will be shifted to the left. For example, when θ=81° and the viewpoint is 9, the pixels in the first row are V0, V1, V2...V8...V0, V1, V2...V8, and the pixels in the second row are V2, V3, V4...V1...V2 , V3, V4...V1, and so on. The inclination angle of grating stripes does not change with the number of viewpoints, but the arrangement of pixels is related to the number of viewpoints and the inclination angle of the grating, and the pi...

Abstract

The invention is applied to the technical field of stereoscopic display and provides a multi-viewpoint LED (Light Emitting Diode) free stereoscopic display device. The multi-viewpoint LED free stereoscopic display device comprises an LED display screen and optical gratings; pixels of the LED display screen are synthesized by RGB (Red Green Blue) three-primary-color light emitting chip; the ith row of pixels which are obliquely arranged on the LED display screen for the pixels at the same viewpoint are moved by ni is equal to mod(round(i-1) is multiplied by tantheta),N) pixels relative to the pixels of the i-1th row; theta is larger than 0 degree and smaller than or equal to 85 degrees; N is the number of viewpoints; a pitch of the optical gratings is expressed as follows: Nd costheta is less than or equal to P is less than or equal to (N plus 0.5)d costheta; the distance D between the optical grating and the LED display screen is equal to (P is multiplied by L) / (E plus P). According to the multi-viewpoint LED free stereoscopic display device, the optical gratings and the pixels are obliquely arranged; the visual range of the same viewpoint in the horizontal direction is expanded; the visual area overturn is reduced to a certain extent; the resolution ratio of the viewpoints is compensated by the adjacent pixels on two sides for the pixels of the same viewpoint; in addition, the pixels of the same viewpoint are obliquely arranged and are uniformly distributed on the whole screen, so that the display pictures are more uniform; the comfort is improved.
