ABSTRACT:
There is provided a display apparatus including a data drive IC. The data drive IC includes a current-mode analog to digital converter (DAC) comprising a plurality of dynamic circuits (instead of conventional level shifters). In response to an enable signal received, each of the dynamic circuits convert a bit of an image data signal received from a signal input circuit into a high voltage level and outputs the resulting signal to a current switch that outputs current to a current node connected to a pixel. The data drive IC including the dynamic circuit has reduced chip area and reduced power consumption (compared to conventional ones comprising a plurality of level-shifters).
