DATA DRIVING METHOD FOR DRIVING A DISPLAY PANEL WHICH APPLYING A DIGITAL DRIVING VOLTAGE, A DATA VOLTAGE, AND AN ANALOGUE DRIVING VOLTAGE IN A DRIVING APPARATUS SUCCESSIVELY, A DATA DRIVING CIRCUIT FOR PERFORMING THE SAME AND A DISPLAY DEVICE HAVING THE SAME

摘要

PURPOSE: A data driving method for driving a display panel, a data driving circuit for performing the same, and a display device having the same are provided to prevent defect of burning a driving chip by secluding an analogue driving voltage in a state that the digital driving voltage is applied abnormally.;CONSTITUTION: A display device comprises a display panel and a drive unit(800) driving the display panel. The display panel comprises a plurality of pixels electrically connected to a plurality of gate lines and a plurality of data lines. Each pixel comprises the thin film transistor, the liquid crystal capacitor electrically connected to the thin film transistor, and the storage capacitor. The drive unit comprises a timing control unit(200), a first voltage generating unit(300), a second voltage generating unit(400), a gamma voltage generator(500), a data driving circuit(600) and a gate driving circuit(700). The first voltage generating unit includes a regulator. The second voltage generating unit includes a dc-dc converter.;COPYRIGHT KIPO 2010
