Embodiment

[0033] The present invention provides a method for controlling POV display devices to display images, which is mainly used to control POV rotating LED display devices to display color images, and its operation principle diagram is as follows figure 1 As shown, its radial color modulo technology based on color images can quickly perform image modulo operations after reading images of any color and content through a program on a mobile terminal. The image display angle and other functions are finally converted into a set of data that can run on the single-chip microcomputer to control the luminous intensity of RGB LED red, green and blue, and transmit the data to the POV rotating LED display device through the wireless data transmission module displayed on the The present invention also provides a method for displaying animations, which is mainly used to control the POV rotating LED display device to display color animations, and each frame of the animation is respectively model...

Abstract

The invention provides a method for controlling a POV display device to display images and animation. The method for displaying color images comprises the following steps that firstly, a round interesting area obtained from an image represented by an RGB color model serves as an image to be displayed; secondly, the image to be displayed is modularized in the radial direction and converted into a set of data which can operate on the display device and control light-emitting intensity of LED lamps; thirdly, the data are sent to the display device in a wireless mode, the display device extracts the data, and the LED lamps are controlled to display the image to be displayed in the rotating process. By means of the method for controlling the POV display device to display the images and the animation, free wireless switching between the images and the animation can be achieved for the display device, a user can zoom the images or the animation displayed by the display device, change the display angle, the content, the hue and the like of the images or the animation, and user experience is greatly improved.

Description

technical field [0001] The present invention relates to the technical field of information display, in particular to a method for controlling a POV display device to display images and a method for displaying animations. Background technique [0002] POV rotating LED display technology utilizes the persistence of vision of the human eye. When a mechanical structure (such as a motor, wheel, etc.) drives the LED column to rotate, the LED column will display the state of the position when it runs to a certain position, and the next After the position is displayed, the state of the next position is displayed. When the LED column rotates fast enough, one column of display devices can complete the display of all images. The scanning process is realized by rotating the mechanical structure to replace the position of the LED column. [0003] The existing POV rotating LED display device needs to use computer software to process the picture to be displayed first, generate picture dat...
