Detailed Description

The principles and features of this invention are described below in conjunction with the following drawings, which are set forth by way of illustration only and are not intended to limit the scope of the invention.

In the description of the present invention, it should also be noted that, unless otherwise explicitly specified or limited, the terms "disposed," "mounted," and "connected" are to be construed broadly, e.g., as meaning fixedly connected, detachably connected, or integrally connected; can be mechanically connected or connected by pipelines; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As shown in fig. 1 and 2, the naked eye 3D display device based on the POV principle includes a motor 3, a rotary vane 4 is fixedly connected to an output end of the motor 3, and a plurality of RGB beads 5 are uniformly arranged on a blade of the rotary vane 4. The display equipment further comprises a controller, the motor 3 and the RGB lamp beads 5 are electrically connected with the controller, and the controller controls the rotating speed of the motor 3 and the on-off, light and shade and color of the RGB lamp beads 5 according to the input 3D display image.

POV (persistence of vision) principle, which is called persistence of vision. That is, when the human eyes observe the scenery, the light signal is transmitted into the brain nerve, a short period of time is needed, after the action of the light is finished, the visual image does not disappear immediately, the residual vision is called 'afterimage', and the phenomenon of vision is called 'persistence of vision'.

Vision is actually imaged by the lens of the eye, and the photoreceptor cells sense light and convert the light signals into nerve currents which are transmitted back to the brain to cause human vision. The sensitization of the photoreceptor cells is by some of the photopigments, which take some time to form, which forms the mechanism of visual pause.

The invention is designed based on the principle, the rotary vane 4 rotates at high speed, a plurality of RGB lamp beads 5 are equally distributed on each blade of the rotary vane 4, each RGB lamp bead 5 is electrically connected with the controller, and the controller controls each RGB lamp bead 5 to complete the actions of switching, brightness and color control.

Therefore, the controller can calculate the staying position of the blade of the rotary vane 4 at a certain time node through the rotating speed of the motor 3, analyze and judge the light and shade and color information of each pixel point of the 3D image corresponding to the staying position of the blade of the rotary vane 4 according to the input 3D image information needing imaging, and control the on-off, light and shade and color information of each RGB lamp bead 5 on the blade to be consistent according to the information. In the rotation process of the motor 3, the controller performs the operation control in real time, so that the 3D image content to be displayed is displayed. Based on the POV principle, the visual effect of naked eye 3D is generated.
