Embodiment Construction
[0041] The parallel LED driving method based on three-dimensional display includes the following steps:
[0042] 1) Decompose the entire LED screen into M rows×N columns of sub-screens, each sub-screen contains i rows×j columns of color LED tubes, each sub-screen corresponds to a driving circuit, and the images of each sub-screen are displayed in parallel at the same time;
[0043] 2) Each driving circuit sends a column of image signals in the sub-screen to a column of LEDs on the sub-screen at the same time, so that a column of LEDs is displayed at the same time, and the image display of the entire sub-screen is realized through sequential scanning of different columns;
[0044] 3) The image displayed on each sub-screen is a binary image, and the grayscale image is realized through the sequential superposition of binary images;
[0045] 4) The display time of each row of LEDs is 1 / [R×F×(2 x -1)×j] seconds, where R is the motor speed (rotation / second), F is the number of imag...
