Display device having high aperture ratio and low power consumption
View Patent ↗A display device includes a plurality of pixels arranged in a column direction and a row direction, a plurality of data lines and a data driving part configured to apply data signals to the data lines. The data lines are connected with one of the pixels of a k-th column (‘k’ is a natural number) and one of the pixels of a (k+1)-th column in an odd-numbered row. The data lines are connected with one of the pixels of a (k+1)-th column and one of the pixels of a (k+2)-th column in an even-numbered row. As a result, a pseudo dot inversion drive pattern may be implemented while driving the data lines in accordance with a columnar polarity inversion scheme.

The display device of claim 1 , wherein the data diving part is configured to apply a data signal having a first polarity to an (m+1)-th data line (‘m’ is a natural number), and to apply a data signal having an opposed second polarity to each of an m-th data line and an (m+2)-th data line adjacent to the (m+1)-th data line during one frame.
3. The display device of claim 1 , further comprising:
a plurality of gate lines connected with the pixels, and
wherein an n-th gate line (‘n’ is a natural number) is connected with one of the pixels of an odd-numbered column, and an (n+1)-th gate line is connected with one of the pixels of an even-numbered column.
4. The display device of claim 3 , wherein a pair of the gate lines is disposed in between a corresponding pair of immediately adjacent pixel rows.
5. The display device of claim 4 , further comprising a gate driving part configured to apply respective gate signals to respective ones of the gate lines.
6. The display device of claim 5 , wherein the data driving part is disposed adjacent to a longer side of a display panel, and the gate driving part is disposed adjacent to a shorter side of the display panel.
7. The display device of claim 1 , wherein the pixels comprise red, green and blue pixels arranged in a row direction.
8. A display device comprising:
a plurality of pixels arranged in a column direction and in a row direction;
a plurality of data lines, each of the plurality of data lines being directly connected with one pixel of a (k+1)-th column (‘k’ is a natural number) and one pixel of a (k+2)-th column to provide data signals and not directly connected with a pixel of a k-th column in a j-th row (‘j’ is a natural number), a (j+1)-th row and a (j+2)-th row, and directly connected with one pixel of a k-th column and one pixel of a (k+1)-th column to provide data signals and not connected with a pixel of a (k+2)-th column in a (j+3)-th row, a (j+4)-th row and a (j+5)-th row; and
a data driving part configured to apply a-data signal to the plurality of data lines,
wherein the each of the plurality of data lines sequentially supplies data signals to the one pixel of the (k+1)-th column in the (j+2)-th row, the one pixel of the (k+2)-th column in the (j+2)-th row, the one pixel of the (k+1)-th column in the (j+3)-th row and the one pixel of the k-th column in the (j+3)-th row.
9. The display device of claim 8 , wherein the data diving part is configured to apply a data signal having a first polarity to an (m+1)-th data line (‘m’ is a natural number), and to apply a data signal having a second polarity to each of an m-th data line and an (m+2)-th data line adjacent to the (m+1)-th data line during one frame.
10. The display device of claim 8 , further comprising:
a plurality of gate lines connected with the pixels, and
wherein a n-th gate line (‘n’ is a natural number) is connected with one of the pixels of an odd-numbered column, and a (n+1)-th gate line is connected with one of the pixels of an even-numbered column.
