[0066] When the human eye observes the scene, the light signal is transmitted to the brain nerve, and it takes a short period of time. After the effect of light is over, the visual image does not disappear immediately. This residual vision is called "after image". This phenomenon of vision It is cal...

Abstract

The invention discloses a holographic display method and device and a readable storage medium, and the method comprises the following steps: determining a spiral tangent plane of a phase surface of aplane display source according to the angular speed and line scanning time of the plane display source; and assigning pixel data of each intersected pixel point of the spiral tangent plane and the holographic image to be displayed to the pixel point corresponding to the phase surface according to the mapping relationship between the phase surface and the pixels of the spiral tangent plane, and taking the assigned phase surface as display frame data. According to the scheme, the delay distortion is determined according to the angular velocity of the display source and the line scanning time, and the delay distortion is compensated and eliminated through the algorithm so as to display the undistorted holographic image.

Description

technical field [0001] The present invention generally relates to the field of display technology, and in particular to a holographic display method, device and readable storage medium. Background technique [0002] Relying on the principle of persistence of vision, the rotating holographic display achieves multi-phase display through the constant speed rotation of the display, and has reached the real three-dimensional display. [0003] With the improvement of display resolution requirements, LCD (Liquid Crystal Display; Liquid Crystal Display) or OLED (Organic Light-Emitting Diode; Organic Light-Emitting Diode; Organic Light-Emitting Diode) can be used as the display source. However, since LCD and OLED display in one frame , is refreshed line by line, and there is a display delay between adjacent lines. During the rotation of the display source, there will be a delay in the angular position of the pixel display, which will cause a frame of the original flat display to be d...
