摘要
A display device comprises an array of light emitting diode zones in a display area. The display device further comprises a control circuit to generate dimming signals to control respective duty cycles for driving the light emitting diode zones during a frame. The display device further comprises an array of driver circuits distributed in the display area of the display device. Each of the driver circuits receives the respective duty cycle for the frame at a first time and receives an update signal at a second time. Each driver circuit drives one of the light emitting diode zones according to the respective duty cycles of the dimming signals in response to the update signal. Different groups of driver circuits start driving the respective light emitting diode zones at different respective offset times during the frame.
