Abstract

A display apparatus includes a plurality of pixels arranged in rows and columns, each pixel column extends in a first direction and each pixel row extends in a second direction crossing the first direction, a first data line extending in the first direction and configured to transfer a data voltage to pixels included in at least two pixel columns, and for each pixel row, a first gate line extending in the second direction and disposed at a first side of the pixel row, and a second gate line extending in the second direction and disposed at a second side of the pixel row, the first and second sides of the pixel row are opposite to each other. In a pair of adjacent pixel columns, pixels, which are connected to the first gate line of their respective pixel row, are arranged in a zigzag arrangement in the first direction.

First claim

What is claimed is:

1. A display apparatus, comprising:
a plurality of pixels arranged in a plurality of pixel rows and a plurality of pixel columns and comprising red, green and blue pixels;
a first data line extending in a first direction and configured to transfer a data voltage to pixels in at least two adjacent pixel columns;
a first gate line extending in a second direction crossing the first direction, the first gate line being disposed at a first side portion of a first pixel row and connected to all red pixels of the first pixel row; and
a second gate line extending in the second direction, the second gate line being disposed at a second side portion of the first pixel row, the first and second side portions of the first pixel row being opposite to each other, wherein the second gate line is connected to all green pixels of the first pixel row,
wherein the first pixel row includes a first green pixel followed by a first red pixel followed by a second green pixel, followed by a second red pixel, without intervening pixels disposed therebetween, and
wherein the display apparatus further comprises a third gate line and a fourth gate line, wherein a second pixel row comprised entirely of blue pixels is disposed between the third and fourth gate lines, wherein the blue pixels disposed in the second pixel row are alternately connected to the third and fourth gate lines.

2. The display apparatus of claim 1 , wherein the red and green pixels of the first pixel row are alternately arranged.

3. The display apparatus of claim 1 , wherein the first gate line is driven prior to the second gate line.

4. The display apparatus of claim 1 , further comprising a second data line adjacent to the first data line, wherein the first data line and the second data line receive data voltages of different polarities from each other, and the data voltages charged in the plurality of pixels have a polarity inversion pattern where the data voltages charged in two neighboring pixels, disposed in a same pixel row and between the first and second data lines, have the same polarity.

5. A display apparatus, comprising:
a plurality of pixels arranged in a plurality of pixel rows and a plurality of pixel columns and comprising red, green and blue pixels, the plurality of pixel rows including a first pixel row including only green and red pixels, a second pixel row including only green and red pixels, and a third pixel row including only blue pixels, wherein the first pixel row is spaced apart from the second pixel row in a first direction and the second pixel row is spaced apart from the third pixel row in the first direction;
a first data line extending in the first direction and configured to transfer a data voltage to pixels in at least two adjacent pixel columns;
a first gate line extending in a second direction crossing the first direction, the first gate line being disposed at a first side portion of the first pixel row and connected exclusively to red pixels of the first pixel row;
a second gate line extending in the second direction, the second gate line being disposed at a second side portion of the first pixel row, the first and second side portions of the first pixel row being opposite to each other, wherein the second gate line is connected exclusively to green pixels of the first pixel row;
a third gate line extending in the second direction, the third gate line being disposed at a first side portion of the third pixel row; and
a fourth gate line extending in the second direction, the fourth gate line being disposed at a second side portion of the third pixel row, the first side portion of the third pixel row and the second side portion of the third pixel row being opposite to each other,
wherein the third and fourth gate lines are exclusively connected to the blue pixels disposed in the third pixel row and the blue pixels disposed in the third pixel row are alternately connected to the third and fourth gate lines.

6. The display apparatus of claim 5 , wherein the red and green pixels of the first pixel row are alternately arranged.

7. The display apparatus of claim 5 , wherein the first gate line is driven prior to the second gate line.

8. The display apparatus of claim 7 , further comprising a second data line adjacent to the first data line, wherein the first data line and the second data line receive data voltages of different polarities from each other, and the data voltages charged in the plurality of pixels have a polarity inversion pattern where the data voltages charged in two neighboring pixels, disposed in a same pixel row and between the first and second data lines, have the same polarity.

9. The display apparatus of claim 1 , wherein the display apparatus includes fewer data lines than gate lines.

10. The display apparatus of claim 1 , wherein there are ⅓, ¼, or ⅙ as many data lines within the display apparatus as there are gate lines.
