Display apparatus and method for driving the same

A display apparatus, comprising:

• a first base substrate;
• a second base substrate facing the first base substrate;
• a plurality of gate lines arranged on the first base substrate to sequentially receive a plurality of gate signals;
• a plurality of data lines to receive a data signal, the data lines being electrically insulated from and crossing with the gate lines to define a plurality of pixel areas, each pixel area comprising an effective display area configured to display an image and a non-effective display area adjacent to the effective display area;
• a plurality of pixels arranged by row in the pixel areas, wherein each row of pixels corresponds to one of the plurality of gate lines;
• and
• a black matrix disposed between the first base substrate and the second base substrate to partially cover the effective display area of a pixel corresponding to a last gate line, wherein the black matrix covers a first portion of the effective display area of the pixel corresponding to the last gate line but does not cover the first portion of the effective display area of a pixel corresponding to another gate line;
• wherein each pixel comprises:
• a first sub pixel to receive the data signal in response to a corresponding gate signal, the first sub pixel being charged to a first pixel voltage;
• and
• a second sub pixel to receive the data signal in response to the corresponding gate signal, the second sub pixel being charged to a second pixel voltage, and
• wherein a pixel corresponding to a gate line other than the last gate line further comprises:
• a voltage controller to control the first pixel voltage and the second pixel voltage in response to a next gate signal after the corresponding gate signal.

A method for driving a display apparatus, comprising:

• charging a first sub pixel to a first pixel voltage and charging a second sub pixel to a second pixel voltage in response to a present gate signal, the first sub pixel and the second sub pixel being arranged in a first pixel corresponding to a last pixel row;
• controlling a voltage level of a third pixel voltage charged in a third sub pixel and a fourth pixel voltage charged in a fourth sub pixel in response to the present gate signal, the third sub pixel and the fourth sub pixel being arranged in a second pixel corresponding to a previous pixel row before the last pixel row;
• and
• controlling a voltage level of the first pixel voltage and the second pixel voltage in response to a dummy gate signal received from a dummy gate line, the dummy gate line being connected to the first pixel corresponding to the last pixel row.
