摘要： Disclosed is a liquid crystal display panel, a method for driving the same, and a liquid crystal display apparatus using the same which can improve visibility and transmittance in a multi-domain VA mode. The liquid crystal display panel includes a plurality of sub-pixels each having first and second gray scale regions which are split up and down and have different areas, the first and second gray scale regions of one sub-pixel having a staggered arrangement with respect to those of an adjacent sub-pixel; a plurality of thin film transistors for independently driving the first and second gray scale regions; a plurality of data lines connected to the thin film transistors, for generating first and second data signals to be respectively supplied to the first and second gray scale regions; and a plurality of gate lines for driving the plurality of thin film transistors by a horizontal period unit. The thin film transistors are connected to the first and second gray scale regions so that the first gray scale regions are driven when one of the plurality of gate lines is driven and the second gray scale regions are driven when another gate line is driven.

摘要： The present invention is directed to a liquid crystal display device and a method for driving the same for a fast transition into a bend state at initial operation such as immediately after power is inputted in a liquid display device with an OCB mode. According to one feature of the present invention, as power is inputted, a timing controller controls to output at least one of a gate voltage for a scan signal, a data voltage for a picture signal, and a driving voltage for a backlight by outputting a first switching signal to a switching unit, and controls to output one of an external bias voltage and a common electrode voltage by outputting a second switching signal to the switching unit so that fast transition into bend state of liquid crystal arranged in a LCD panel is accomplished. As a result, by applying a voltage of less level than that of the typical common electrode voltage to the LCD panel, as DC voltage of at least 10 volt to 20 volt is applicable to a common electrode, time for transition into bend state can be reduced at initial operation of the liquid crystal display device using the LCD panel with OCB mode.
