Abstract

An LED driving apparatus for driving an LED array including a plurality of digital-to-analog converters and a plurality of data latch circuits is provided. Each of the digital-to-analog converters is coupled to a corresponding LED, and outputs a driving current according to n-bits pixel data to drive the corresponding LED. Each of the plurality of data latch circuits stores the n-bits pixel data, and is coupled to a corresponding digital-to-analog converter to control the n-bits pixel data to be written into the corresponding digital-to-analog converter. Each of digital-to-analog converters includes n sub-driving current generating circuits. Each of the n sub-driving current generating circuits generates a sub-driving current having a current value corresponding to a bit order of a bit of the n-bits pixel data. The driving current is generated by summing up n sub-driving currents.
