E3 is connected to E2 and SLS, corresponding to the pixel, through the third switch. The CC is a fourth switch including a control terminal, a first contact and a second contact. The control output of the fourth switch is connected to the FLS corresponding to this pixel. The first contact is connected to the fourth switch E2, and the second terminal of the fourth switch is connected to the CE. A fourth switch is turned on to change the pixel voltage E2 when the FLS provides a sweep signal that controls the voltage difference between the pixel E2 and the CE so that it does not equal zero during the time of turning on. In 2D mode, the FLS provides a sweep signal to control the first switch, the second switch, and the fourth switch. At pixel E1 and E2 of the pixel, a data signal comes from the DL to be able to display the image corresponding to the 2D image. E2 of the pixel is connected to the CE when the fourth switch is turned on, so that the pixel voltage E2 is first changed, and then the FLS turns off the first switch and the second switch. The SLS provides a sweep signal to turn on the third switch, so that the pixel E2 is electrically connected to the pixel E3. At E3 of the pixel, a data signal from the pixel E2 is input to be able to display the image corresponding to the 2D image, so that the pixel voltage E2 after the first change is changed for the second time through the pixel E3. The third switch adjusts the voltage difference between the pixel's E2 and the pixel's E3 so that it does not equal zero during the time of turning off. In this case, when scanning a FLS corresponding to a row of pixels, a SLS corresponding to the previous row of pixels is scanned, which is scanned later on adjacent to this row of pixels. In 3D mode, the SLS turns off the third switch, and the FLS provides a sweep signal to turn on the first switch and the second switch. At E1 of the pixel and E2 of the pixel, a data signal comes from the DL to be able to display the image corresponding to the 3D image. CC affects E2 of the pixel to change the voltage of E2 of the pixel. E3 of the pixel is in the image display state corresponding to the dark screen when the third switch is turned off.EFFECT: reduction of colour distortion in 2D and 3D mode, improvement of window format in 2D mode and reduction of cross-distortion of signals for two eyes in 3D mode.19 cl, 6 dwg
