Abstract
Embodiments relate to a micro light-emitting-diode (mLED) cell that includes a mLED and a controller. The controller receives a brightness data signal and generates a driving signal corresponding to the brightness data signal. The controller is coupled to the mLED for providing the driving signal that turns on the mLED for first times and turns off the mLED for second times for a duration of a cycle. The driving signal causes a current density in mLED to be above a threshold value when the mLED is turned on.
