Abstract:
A driver device for driving light emitting elements comprises a data latch having an input coupled to an input signal, a current control circuit having an input coupled to the data latch, and an output coupled to the input of an output stage, the latter being configured to drive the light emitting elements. The driver device has a power control circuit having an input coupled to the output of the data latch and an output coupled to the input of the current control circuit. The power control circuit is configured to control the current control circuit and the latter is configured to deliver a first current when the data inputted to the power control circuit is in a first state and a second current when at least part of the data inputted to the power control circuit is in a second state.
