In Fig. 1, Vcom is public electrode voltages, and public electrode voltages are also reference voltage in the present embodiment.
V0 ~ V7 is that show electrode voltage is also referred to as gamma voltage, using frame as 8 gamma voltage groups of period-producer, such as the
The V0 of one frame and the second frame forms gamma voltage group.According to the operation principle that pressure differential liquid crystal works, the pressure difference is liquid crystal
Driving voltage, different pressure differences corresponds to different grayscale, that is, the brightness that liquid crystal display is shown, forms in the present embodiment
8 grayscale.Certainly according to the requirement of display demand, 64 ranks or more can be designed to.
In the corresponding first frame of same pixel and the second frame, gamma voltage is equal with public electrode voltages difference, polarity
On the contrary, two gamma voltage constitutes gamma voltage group, two voltages that gamma voltage group includes are formed symmetrically with reference voltage
Relationship.In the present embodiment, 8 gamma voltage groups, every group of gamma voltage correspond to same grayscale.Two v7 corresponding are highests
Grayscale, two v0 corresponding are minimum gray scales, and minimum gray scale corresponds to pressure difference minimum, that is, brightness minimum.
It should be noted that in the present invention, every difference, voltage difference or pressure difference of being related to is equal, pressure is only represented
Difference value is identical.
In the present embodiment, because public electrode voltages are constant, according to the demand of display grayscale, in multigroup gamma voltage

Within the scope of corresponding first gamma voltage and the second gamma voltage；Or public electrode voltages can also be more than minimum gray scale and correspond to
Relative larger value in gamma voltage group, or correspond to the relative small value in gamma voltage group less than minimum gray scale.

Value it is different, the grayscale resulted between the adjacent two field pictures of pixel is different, and the switch speed between adjacent two frame is more than people
The recognizable set of eye, the persistence of vision of human eye can be appreciated that the mixed effect of different brightness in time, and then improve vision
Effect, but the brightness shown is different, human eye may feel that the effect of flicker.
In order to solve the problems, such as above-mentioned flicker, need to be adjusted by backlight, specific implementation is according to
One pressure difference and the second pressure difference are compared, and the first pressure difference then means that greatly brightness of display screen is larger, the second pressure difference compared with
It is small, mean that brightness of display screen is smaller.There are correspondence, backlight can be directed to display screen for backlight and display area
Region part is adjusted, and needs exist for control backlight to implementing local dimming compared with small pressure difference value correspondence image（local
dimming）It compensates.
