Abstract

A liquid crystal display panel includes a sub-pixel array, a plurality of scan lines, and a plurality of data lines. The sub-pixel array has a plurality of sub-pixels arranged in array. Any two neighboring scan lines of the scan lines and a row of the sub-pixels disposed between the two neighboring scan liens are electrically connected. The sub-pixels arranged in odd rows are electrically connected to the odd-numbered data lines, and the sub-pixels arranged in even rows are electrically connected to the even-numbered data lines. Thus, the liquid crystal display panel is able to reduce mura phenomenon through the above-mentioned layout. A driving method of the above-mentioned liquid crystal display panel is also provided.

Claims (27)

1. A liquid crystal display panel, comprising:

a sub-pixel array comprising a plurality of sub-pixels arranged in array;

a plurality of scan lines, wherein any two neighboring scan lines of the scan lines and a row of the sub-pixels disposed between the two neighboring scan lines are electrically connected; and

a plurality of data lines, wherein the sub-pixels arranged in odd rows are electrically connected to the data lines which are odd-numbered, and the sub-pixels arranged in even rows are electrically connected to the data lines which are even-numbered.

2. The liquid crystal display panel as claimed in claim 1 , wherein each of the sub-pixels comprises:

an active device electrically connected to one of the scan lines and one of the data lines; and

a pixel electrode electrically connected to the active device.

3. The liquid crystal display panel as claimed in claim 1 , wherein in a same row of the sub-pixels, the sub-pixels arranged in even columns are connected to one of the scan lines, and the sub-pixels arranged in odd columns are connected to another one of the scan lines.

4. The liquid crystal display panel as claimed in claim 1 , wherein two neighboring sub-pixels of the sub-pixels in a same row are together connected to one of the data lines.

5. The liquid crystal display panel as claimed in claim 1 , wherein the sub-pixels comprise a plurality of first primary color sub-pixels arranged in a same row, a plurality of second primary color sub-pixels arranged in a same row, and a plurality of third primary color sub-pixels arranged in a same row, and the first, the second, and the third primary color sub-pixels in each column are alternately arranged in sequence.

6. The liquid crystal display panel as claimed in claim 5 , wherein in a same column of the sub-pixels, the neighboring first, second, and third primary color sub-pixels together form a pixel unit.

7. The liquid crystal display panel as claimed in claim 1 , wherein the sub-pixels comprise a plurality of first primary color sub-pixels arranged in a same column, a plurality of second primary color sub-pixels arranged in a same column, and a plurality of third primary color sub-pixels arranged in a same column, and the first, the second, and the third primary color sub-pixels in each row are alternately arranged in sequence.

8. The liquid crystal display panel as claimed in claim 7 , wherein in a same row of the sub-pixels, the neighboring first, second, and third primary color sub-pixels together form a pixel unit.

9. The liquid crystal display panel as claimed in claim 7 , wherein the first primary color sub-pixels of the sub-pixels are arranged in a first column, a fourth column, . . . , and a (3m+1)th column, the second primary color sub-pixels of the sub-pixels are arranged in a second column, a fifth column, . . . , and a (3m+2)th column, the third primary color sub-pixels of the sub-pixels are arranged in a third column, a sixth column, . . . , and a (3m+2)th column, and in represents a natural number.

10. The liquid crystal display panel as claimed in claim 1 , further comprising a plurality of dummy sub-pixels disposed at two sides of the sub-pixels and electrically connected to the outermost two data lines.

11. The liquid crystal display panel as claimed in claim 1 , wherein the outermost two data lines are electrically connected to each other.

12. The liquid crystal display panel as claimed in claim 1 , further comprising a common electrode, wherein polarities of the neighboring sub-pixels with respect to the common electrode are opposite.

13. A driving method for driving the liquid crystal display panel as claimed in claim 1 , the driving method comprising:

inputting a signal with a first polarity to the odd-numbered data lines and inputting a signal with a second polarity to the even-numbered data lines.

14. The driving method as claimed in claim 13 , wherein a signal with a positive polarity is inputted to the odd-numbered data lines, and a signal with a negative polarity is inputted to the even-numbered data lines, so as to drive the sub-pixel array through applying a column-inversion driving method.

15. The driving method as claimed in claim 13 , wherein a signal with a first inverted polarity is inputted to the odd-numbered data lines, and a signal with a second inverted polarity opposite to the first inverted polarity is inputted to the even-numbered data lines, so as to drive the sub-pixel array through applying a dot-inversion driving method.

16. A liquid crystal display panel, comprising:

a sub-pixel array comprising a plurality of sub-pixels arranged in array;

a plurality of scan lines, wherein any two neighboring scan lines of the scan lines and a row of the sub-pixels disposed between the two neighboring scan lines are electrically connected; and
