摘要: The present invention provides a transistor switch on light emitting device channel, the receiving control voltage VG. A current source circuit controls requiring minimum VR for normal operation. further dynamic headroom controller which compares VS at outflow end of with to determine relationship between and when VG is higher than reference VH, adjusts difference accordingly.
