Embodiment Construction

[0031] Please refer to figure 1 . figure 1 A schematic diagram illustrating a liquid crystal display panel according to a first embodiment of the present invention. On the liquid crystal display panel 100, there are multiple data lines, such as D 1 、D 2 ; and multiple scan lines, such as G 1 , G 2 and G 3 . scan line G 1 , G 2 , G 3 , ... are substantially parallel to a first direction (horizontal direction), and the data line D 1 、D 2 , ... are arranged substantially parallel to a second direction (vertical direction). In addition, the scan line G 1 , G 2 , G 3 ...and data line D 1 、D 2 、D 3 , ... do not intersect each other.

[0032] On the liquid crystal display panel 100, the scanning line G 1 , G 2 , G 3 , ... and data line D 1 、D 2 , ... can enclose multiple display areas, and these display areas are arranged in an array. In each display area, a pixel P is configured, such as a pixel P 11 ,P 12 ,P 21 and P 22 . In this way, a pixel array (pix...

Abstract

The invention discloses a pixel circuit and a drive method thereof. The pixel circuit comprises a first scanning line, a second scanning line, a data wire, three switches and a pixel. Each of the three switches comprises a first end, a second end and a control end respectively. The pixel comprises a first sub-pixel and a second sub-pixel. The first end of the first switch is coupled with the datawire. The control end of the first switch is coupled with the first scanning line. The first end of the second switch is coupled with the second end of the first switch. The control end of the secondswitch is coupled with the second scanning line. The first end of the third switch is coupled with the data wire. The control end of the third switch is coupled with the first scanning line. The first sub-pixel is coupled with the second end of the second switch to penetrate the second switch and the first switch and then is coupled with the data wire. The second sub-pixel is coupled with the second end of the third switch to be coupled with the data wire through the third switch.

Description

technical field [0001] The present invention relates to a pixel circuit and its driving method, more specifically, to a pixel circuit capable of improving color washout and its driving method. Background technique [0002] Liquid crystal displays (LCDs) have gradually become the mainstream of the market due to their advantages of good space utilization efficiency, low power consumption, and no radiation. However, the market's requirements for liquid crystal displays such as wide viewing angle, high resolution, and large size are also a trend. [0003] However, when a user views a liquid crystal display with a larger viewing angle, the image viewed by the user will have a color washout phenomenon, which will result in distorted color display. The so-called color fading refers to the whitening of the picture when viewing the LCD display at a large viewing angle, that is, when viewing the LCD display at a larger viewing angle, the brightness of the middle and low gray scales i...
