Abstract
A method includes sequentially coupling, by a switching module of a circuit, each cell of a plurality of cells to a driver module. Each cell of the plurality of cells includes a light emitting diode (LED) configured to activate based on a control voltage at a respective cell of the plurality of cells. The method includes driving, by the driver module, the control voltage of the respective cell based on a reference current when the switching module sequentially couples the respective cell to the driver module.
