Distinguish the Common Cathode from the Common Anode of LED Display Pin
Abstract: Find out the common cathode and the common anode: firstly, we find out one power supply (from 3V to 5V) and one resistance of 1K (or several hundreds of ohms); the VCC will be connected to the any two feet of th...
Explanation of Important Parameters of LED
Abstract: 1.Forward current If: It is the forward current when the light-emittingdiode normally gives off light. The IF which is less than 0.6IFm shall be chosen according to the requirement in actual use. 2.Forward volta...
Influence of the constant current drive and non-constant current drive on the LED Display
Abstract: Effect of Display: Because the light emitting diode(LED) basically belongs to current sensitive device and the decentrality of the positive voltage drop is high and related to the temperature; in order to ensure...
