Jinrui Guang electrical welcome your call! Two full-color LED display screen, as follows: (1) the so-called static display static display, it is referred to as full-color LED display a character when the corresponding LED will be constant on ON or OFF constant two forms. This approach requires you to display a constant common ground display block (common cathode) or connected to the positive supply (common anode). 8 segments each display line selection blocks respectively with one 8-bit parallel I / O port 8 port line phase, I / O ports as long as the code output section, the corresponding character is led out of the smart screen instructions and keep little changed until the I / O outputs a new segment code. We at its static display mode, when you can get a smaller current high brightness, and it takes less CPU time, the programming is very easy, but then, as a result of each LED display must equipped with a parallel output port, which take up a lot of I / O port resources, this way, it becomes high hardware costs, so that more digits in the display is best not used in this way. (2) dynamic display mode for dynamic display, it is a one way you take turns lighting displays, according to this by way of imitation lit display is commonly called bit scan. The requirements in this way show you monitor select line segments are connected in parallel, mainly by an 8-bit I O port control /; and you bit line selection by additional I / O ports line control. This way, when displayed, you turn the strobe display, to make it possible to stabilize the display, you must use the scanning mode, that is, at some point, we have only one strobe display, and sent over the corresponding Segment led display manufacturer of intelligent, appropriate delay (probably also delay time is about 1-5ms), followed by another one strobe display, and will send the corresponding segment code, and so on ad infinitum, then it You can make full-color LED display you display the corresponding characters. If we can ensure that the cycle time is short enough, we can take advantage of the human eye's persistence of vision effect, to achieve a sense of giving a display. A distribution box distribution box are generally composed of several core components, power switch, AC contactor, sub-switch, timer, SPD. Currently led display wholesale smart, I selected distribution box standardized configuration is basically divided into general distribution boxes and smart power distribution box in two ways: Normal distribution box: distribution box is equipped with a timer, the timer switch can power to the display. Intelligent Power Distribution Box: intelligent distribution box can display real-time temperature and humidity on the screen, intelligent brightness control, you can use the software at any timing or switching power display. Our power distribution box by size classification: 15kW, 30kW, 60kW, 45KW, 90kW, 120kW, 150kW, 180kW.
