Abstract

A light-emitting diode (LED) assembly comprises a plurality of LED cells and a driving circuit. Each of the LED cells includes an LED and a transistor. The LED includes first and second LED layers and an LED electrode. The first LED layer includes a III-V compound semiconductor. The second LED layer is over the first LED layer. The LED electrode is over the second LED layer. The first LED layer is free of an LED electrode. The transistor includes a drain region connected to the first LED layer. The driving circuit is configured to drive the LED cells.
