Abstract
A display panel and a driving method thereof and a display device are disclosed, and the display panel includes two sets of pixel driving circuits; and, for every two adjacent pixel columns for each primary color, an operating voltage line for one pixel column is connected to a first set of pixel driving circuits via a connection point located at a side of a pixel array where the pixels in the first row of a pixel array are located, and an operating voltage line for the other pixel column which is connected to the second set of pixel driving circuits via a connection point located at a side of the pixel array where the pixels in the last row of the pixel array are located. The display panel can ensure the uniformity of the display luminance of the whole display panel.
Claims13
A display panel comprising:
- a first set of pixel driving circuits and a second set of pixel driving circuits;
- and
- a pixel array;
- wherein the display panel includes at least three primary colors, the first set of pixel driving circuits includes a first group of sub-driving circuits having one-to-one correspondence with the at least three primary colors, and the second set of pixel driving circuits also includes a second group of sub-driving circuits having one-to-one correspondence with the at least three primary colors;
- and
- wherein, for every two adjacent pixel columns for each primary color, an operating voltage line that connects with all sub-pixels of the same primary color in one pixel column is connected to a same sub-driving circuit corresponding to the primary color in the first set of pixel driving circuits via a connection point located at a side of the pixel array where pixels in a first row of the pixel array are located;
- and another operating voltage line that connects with all sub-pixels of the same primary color in the other pixel column is connected to another same sub-driving circuit corresponding to the primary color in the second set of pixel driving circuits via a connection point located at a side of the pixel array where pixels in a last row of the pixel array are located.
A method for driving a display panel provided a first set of pixel driving circuits, a second set of pixel driving circuits, and a pixel array, the method comprising:
- for every two adjacent pixel columns for each primary color, connecting an operating voltage that connects with all sub-pixels of the same primary color in one pixel column to a same sub-driving circuit corresponding to the primary color in the first set of pixel driving circuits via a connection point located at a side of the pixel array where pixels in a first row of the pixel array are located, and connecting another operating voltage that connects with all sub-pixels of the same primary color in the other pixel column to another same sub-driving circuit corresponding to the primary color in the second set of pixel driving circuits via a connection point located at a side of a pixel array where pixels in a last row of the pixel array are located;
- and
- allowing the operating voltages connected to the first and second sets of the pixel driving circuits to be equal.
