Abstract:
1. A liquid crystal display (LCD), comprising a TFT-LCD module which comprises a pixel for showing grayscale signal, a data line for transmitting a data signal to the pixel, and a first switching unit for controlling operation of the pixel; the pixel comprising a main sub-pixel and a secondary sub-pixel, and the TFT-LCD module further comprising: a pair of pixel capacitors for reallocating a voltage of the grayscale signal to the main sub-pixel and to the secondary sub-pixel in the same frame, and a second switching unit for controlling the reallocation, characterized in that: the secondary sub-pixel comprises a first sub-pixel and a number of n second sub-pixels, and the TFT-LCD module further comprises a number of n third switching units for controlling operation of each corresponding second sub-pixel, where n is an integer greater than 1; the TFT-LCD module further comprises a control unit for controlling the conduction of the third switching unit depending on the data signal carried by the data line and an adjusting unit for adjusting a number of the third switching units controlled by the control unit, the third switching unit comprises a control end coupled to the control unit, an input end coupled to the first sub-pixel, and an output end coupled to the second sub-pixel; when the LCD displays 3D images, the data signal comprises a grayscale signal and a black image signal; the third switching units controlled by the control unit turn on when the black image signal is transmitted by the data line; the third switching units controlled by the control unit turn off when the grayscale signal is transmitted by the data line; and the third switching units which are not controlled by the control unit remain turned on; when the LCD displays 2D images, the third switching unit turns on.
