TIME DIVISION MODULATION WITH AVERAGE CURRENT REGULATION FOR INDEPENDENT CONTROL OF ARRAYS OF LIGHT EMITTING DIODES

摘要

Current is provided to a segment of light emitting diodes in a plurality of segments of light emitting diodes. Embodiments generate a current and sequentially and separately switch the current to each segment of light emitting diodes in the plurality of segments of light emitting diodes for a corresponding period of time, where the corresponding period of time is based on an average current of the generated current.
