An approach for controlling pixel turn on and turn off within an LED array is described. Turn-on delays for pixels within the LED array is based on the duty cycles of the pixels. The pixels are grouped based on corresponding duty cycles. The turn-on on delay for each pixel is based on the group that includes the pixel, as well as position of the pixel within the group. The LED array is driven by circuitry in a CMOS backplane.

A lighting apparatus includes a light source, a main controller, a AC-DC converter, a dimmer signal extractor, a dimmer interface circuit and an isolating transformer. The AC-DC converter converts an external AC power to a driving current of a DC power for supplying power to the light source according to a control signal received by the main controller. The dimmer signal extractor generates the control signal supplied to the main controller according to a transformed signal. The dimmer interface circuit is connected to a dimmer. The dimmer is disposed on a wall to be operated by a user to generate a dimmer voltage. The dimmer voltage is converted to a dimmer signal. The isolating transformer has a secondary terminal connecting to the dimmer interface circuit and a first terminal connecting to the dimmer signal extractor.
