Element, N number of sub-pixel combinations can show 2NA grayscale.For example, if when a pixel is divided into 2 sub-pixels, 2 sons
Combination of pixels can show 4 grayscale, if a pixel is divided into 3 sub-pixels, 3 sub-pixel combinations can be with table
Reveal 8 grayscale.For a pixel is divided into 2 sub-pixels, due in a pixel there are three types of color, then altogether can be with
Show 43=64 grayscale i.e. 64 colors.
By taking the existing display screen for dividing design 64 colors of realization based on pixel as an example, according to the existing output side Source
Formula, since Source signal can only export 0,1 two states, respectively VSL voltage (0 state) and VSH voltage (1 state),
For fixed voltage value, in this case, can not meet different display pictures simultaneously is in the optimal display state of Flicker.
Theoretically, when the pressure difference between Δ V1 and Δ V2, that is, positive and negative frame pressure difference is smaller, Flicker is more excellent.Therefore to make
Flicker needs to make Δ V1 as close possible to Δ V2, i.e., " VSH-VCOML " is as close possible to " VCOMH-VSL " to optimal.This

Step 2, for any grayscale, the first common voltage, the second common voltage and the first source electricity of the determination are exported
Pole tension determines the second source electrode voltage value for making flashing be in optimum state under current gray, determines the second current source
Electrode voltage value is the corresponding second source electrode voltage of current gray.
For being divided into 2 sub-pixels, each pixel that can show 4 grayscale with a pixel, current display is adjusted
For one of grayscale, can be in most under current gray by adjusting the second source electrode voltage to adjust Flicker to it
Excellent, the second source electrode voltage when Flicker is optimal is the corresponding second source electrode voltage of current gray.Or it can also be first
It determines positive and negative frame pressure difference when Flicker being made to be in optimum state under current gray, is obtained by the calculating of positive and negative frame pressure difference formula
Obtain the corresponding second source electrode voltage of current gray.

VSL voltage, taking median is 1V, and under this state, grayscale L0, L1, L2 and L3 are not Flicker optimum state, and due to frame
Shield it is lower, human eye be easier to perception display screen flashing.
Using previous embodiment calculation method, can determine L0, L1, L2, tetra- kinds of grayscale of L3 correspond to Flicker it is optimal when
The voltage of VSL is respectively as follows: 0.8V, 0.95V, 1.1V and 1.2V.Voltage value according to Flicker VSL when optimal is defeated to source
Signal optimizes out, and the source output signal after optimization is as shown in Figure 3.At this point, each picture of display is in Flicker
Optimal state.This source method of adjustment can efficiently solve difference existing for the former source way of output and show picture
Flicker can not be adjusted to the problem of optimal state simultaneously.
Only need to adjust the VSL value that once can determine under corresponding different grayscale using present invention method, it is subsequent
Given voltage waveform is shown according to pixel, does not need routine adjustment.
Technical solution of the present invention is exported different by controlling Source output signal that is, according to the picture of actual displayed
