Rotating the principle of outdoor LED display is not complicated, the hardware structure is relatively simple, but to make the outdoor display LED display can be stable display of the image or text, you need to overcome the three technical difficulties:
For outdoor rotation LED display, its hardware structure and implementation of the principle are relatively simple, but to ensure that the image can be stable to show the text, in the technical field need to do three points:
1. On the rotation of the screen body to show the phenomenon of drag and drop because of its screen is a single outdoor LED display rotating scan to achieve a cylindrical image display, which makes the pixel display in the horizontal appear viscous, which will form Smear the imagination.Then solve this problem about the outdoor rotating screen rendering effect.
2. With regard to the problem of the rotary screen control circuit, when the system of the rotary screen is operating, the control circuit, as the rotor of the motor rotates, ensures a stable supply environment for the rotating circuit and the display.
3. On the screen brightness of the problem due to the rotation of the outdoor LED display electronic screen works determine the general compared to the ordinary flat outdoor LED display, display each column of the time to be much less, to solve the problem of screen brightness It is very critical.
To make the design of the rotating outdoor LED display has a good display, you need to solve these three problems in the design. For the rotation of the outdoor LED display power supply, the use of fixed at the base of the brush and the rotating metal rail or metal wheel contact way to the system power supply, is a relatively simple and reliable method.
