Abstract
An electronic device includes a local dimming unit, a current driving unit, and a light-emitting diode zone. The local dimming unit generates a dimming control signal according to a current control command. The current driving unit generates a driving signal with a first current or a second current according to the dimming control signal, wherein the second current is greater than the first current. The light-emitting diode zone receives the driving signal and emits light according to the driving signal.
Claims20
An electronic device, comprising:
- a local dimming circuit, configured to generate a dimming control signal according to a current control command;
- a current driving circuit, configured to generate a driving signal with a first current for a general current control command or to generate the driving signal with a second current for a high current control command according to the dimming control signal, wherein the second current is greater than the first current;
- and
- a light-emitting diode zone, configured to receive the driving signal and emit light according to the driving signal,
- wherein the light-emitting diode zone comprises an edge zone having a first light-emitting diode electrically connected to two channels of the current driving circuit.
