Jinrui Guang electrical welcome your call! Two display full-color LED display, as follows: (1) static display so-called static display, it refers to is when full-color LED display a character when the corresponding LED will be constant on pass or constant off two forms. This approach requires you to show common ground constant display of the block (common cathode) or connected to the positive supply (common anode). 8 segments each display block select line, respectively an 8-bit parallel I / O port 8 port line phase, I / O ports as long as the code output section, the corresponding character is instructed out, Shenzhen led display, and maintaining a small change until I / O outputs a new segment code. We at its static display mode, when you can get a smaller current high brightness, and it occupies less CPU time, the programming is very easy, but then, due to each LED display have equipped with a parallel output port, which take up a lot of I / O port resources, so that its hardware cost becomes high, so that more display digits when it is best not used in this way. (2) dynamic display mode for dynamic display mode, it is bit by bit you take turns lighting display, indoor led display, lights up the display in this way by imitation is commonly called bits scan. The requirements in this way show you monitor selected line segment is connected in parallel, mainly by an 8-bit I O port control /; and you bit line selection by additional I / O port line control. This way, when displayed, display turns gating, to make it possible to stabilize the display, you must use scanning mode, that is, at some point, we have only one strobe display, and sent over the corresponding Segment Enshi led display, perform appropriate delays (probably also delay time is about 1-5ms), followed by another strobe display, and will send the corresponding segment code, and so the cycle, then it can make full-color LED display you display the corresponding characters. If you are sure the cycle time is short enough, then we can use the human eye persistence of vision to achieve a sense of giving a display. System Features 1. All the information inputs are high-performance host controller through acquisition, digital processing to dedicated VLSI central processing core, with high-speed memory circuit, a dedicated digital processing circuits, it has the quality of high-performance strong and many other advantages. Power distribution system with comprehensive protection against overvoltage, overcurrent, undervoltage, phase, short circuit or other abnormal conditions have monitoring, automatic protection 2. Video twofold process: display control system with a pure video processing and computer information processing double processing performance. Making information clearer playback picture and flexible. 3. static constant current drive, ensure high-quality display. The fiber optic transmission of digital video signals: strong anti-led full-color display, high transfer rate, transmission distance. 5. The multi-adjustable brightness, easy to operate, easy to use. led display price | 金锐光 electricity (certified) | Enshi led display provided by the Science and Technology Co., Ltd. Yichang 金锐光.
