DATA DRIVER AND DISPLAY APPARATUS HAVING THEM

摘要

The purpose of the present invention is to provide a display apparatus containing a data driver having a reduced circuit area. The display apparatus comprises: a display panel containing a plurality of gate lines and a plurality of pixels connected to a plurality of data lines respectively; a gate driver driving the gate lines; a data driver driving the data lines; and a timing controller which provides a clock signal, a line latch signal and a data signal to the data driver and controls the gate driver. The data driver comprises: a digital-analog converter which consecutively receives data signals corresponding to the data lines respectively and outputs analog image signals; and a switching output unit which consecutively outputs the analog image signals synchronized by the clock signal and output from the digital-analog converter as analog driving signals corresponding to the respective data lines.
