Abstract

A display apparatus includes first-kind data lines and second-kind data lines. Each of the first-kind data lines is connected to one of two pixels arranged in a k-th pixel row and a (k+1)th pixel row. Each of the second-kind data lines is connected to two pixels arranged in different pixel columns in the k-th pixel row and the (k+1)th pixel row. At least two first-kind data lines are consecutively arranged.

First claim

What is claimed is:

1. A display apparatus comprising:
a plurality of gate lines;
a plurality of data line groups, each data line group of the plurality of data line groups comprising eight data lines sequentially arranged and repeating in a first direction in which the plurality of gate lines extend; and
a plurality of pixels connected to the plurality of gate lines and the eight data lines of each data line group of the plurality of the data line groups,
wherein the eight data lines comprise first-kind data lines and second-kind data lines,
wherein each of the first-kind data lines is connected to one of two pixels that are arranged in a k-th pixel row and a (k+1)th pixel row,
wherein each of the second-kind data lines is connected to two pixels that are arranged in different pixel columns in the k-th pixel row and the (k+1)th pixel row,
wherein the first-kind data lines comprise first, second, third, and fourth data lines, and the second-kind data lines comprise fifth, sixth, seventh, and eighth data lines,
wherein the first, second, third, fourth, fifth, sixth, seventh, and eighth data lines are arranged in an order of the third, fifth, sixth, first, second, seventh, eighth, and fourth data lines along the first direction, and
wherein each of the first, second, fifth and eighth data lines respectively receives a first data voltage having a first polarity, and each of the third, fourth, sixth and seventh data lines respectively receives a second data voltage having a second polarity opposite to the first polarity.

2. The display apparatus of claim 1 , wherein the at least two first-kind data lines that are consecutively arranged respectively correspond to the first and second data lines, wherein the third data line is disposed to be spaced apart from the first and second data lines, and wherein the fifth and sixth data lines are disposed between the third data line and the first and second data lines.

3. The display apparatus of claim 1 , wherein the first data line is connected to one of the plurality of pixels arranged in the (k+1)th pixel row, and wherein the second data line is connected to one of the plurality of pixels arranged in the k-th pixel row.

4. The display apparatus of claim 3 , wherein a first group of pixels of the plurality of pixels that is arranged in the k-th pixel row comprises first to sixth pixels connected to the second, third, fifth, sixth, seventh, and eighth data lines, wherein the a second group of the plurality of pixels that is arranged in the (k+1)th pixel row comprises seventh to twelfth pixels connected to the first, fourth, fifth, sixth, seventh, and eighth data lines, wherein the first to twelfth pixels are arranged in a pixel matrix of two rows by six columns, and wherein four pixels arranged in two consecutive pixel columns arranged in the pixel matrix respectively display red, green, blue, and white colors.

5. The display apparatus of claim 4 , wherein a first set of four pixels among a first set of six pixels arranged in a first pixel row of the pixel matrix display the red, green, blue, and white colors, and wherein a second set of four pixels among a second set of six pixels arranged in a second pixel row of the pixel matrix display the red, green, blue, and white colors.

6. A method of driving a display apparatus comprising:
providing pixels arranged in a pixel matrix of two rows by six columns;
connecting the pixels to a plurality of gate lines comprising first and second gate lines;
connecting the pixels to a plurality of data lines comprising first to eighth data lines, wherein the plurality of data lines comprise a first set of four lines and a second set of four lines;
connecting each of the first set of four data lines among the first to eighth data lines to one of the pixels arranged in a first pixel row and a second pixel row;
connecting each of the second set of four data lines among the first to eighth data lines to the pixels arranged both in the first pixel row and the second pixel row;
applying a gate signal to the first gate line during a horizontal period;
applying data voltages to six data lines of the plurality of data lines that are connected to the pixels arranged in the first pixel row; and
selectively applying data voltages to two data lines of the plurality of data lines that are not connected to the pixels arranged in the first pixel row when the data voltages are applied to the six data lines that are connected to the pixels arranged in the first pixel row.
