LIQUID CRYSTAL PIXEL AND PANEL INCLUDING THE SAME

摘要

A liquid crystal pixel and a panel including the same are provided to lower a voltage(Vrn) on another electrode of a liquid crystal cell as much as a lowered amount of a voltage(Vcn) on a pixel electrode of a liquid crystal cell(CLC), thereby exactly measuring a voltage of a pixel driving signal in the liquid crystal cell. A pixel driving signal(Vds) to be transmitted from a data line(DL) corresponding to the first thin film transistor(MN1) to a charging node(CN) is switched. The second thin film transistor(MN2) selectively connects a reference node(RN) to a common voltage line(CML). A liquid crystal cell is connected between the charging node and the reference node. The first capacitor(Crc) of a voltage correction function is connected between the reference node and the common voltage line. A common voltage(Vcom) is supplied to the common voltage line. While a scan signal of a high potential voltage is applied to a corresponding gate line, the first thin film transistor supplies a pixel driving signal(Vds) to a liquid crystal cell on a data line corresponding to the first thin film transistor through the charging node.
