Decoding Micro-LED’s Current Driving Methods

Micro-LED a light emitting diode driven by electric currents, similar to traditional LEDs in display applications it can be driven using passive matrix or active matrix. A third current driving method is the new semi-active matrix driver, which uses a completely different method compared to existing models. Below we will introduce three different circuit designs and their basic theories.

For three decades, white LEDs have depended on rare earth materials such as yttrium aluminum garnet (YAG) layered onto a blue LED chip (Figure 1). Seoul Viosys Co., Ltd. (KOSDAQ: 092190) today announced that it has broken that dependence. It h... READ MORE
