As shown in figure 1, liquid crystal panel drive system is generally divided into three parts, Part I is signal source 110, for producing
Raw picture signal, image information is provided to TCON chips 120, and combines image information, sends corresponding control signal；Second
It is TCON chips 120 to divide, for output control signal and the image information for meeting liquid crystal display panel needs；Part III is liquid
There are multiple pixels in crystal panel 130, liquid crystal panel.
TFT (Thin Film Transistor, thin film transistor (TFT)) the type LCD being widely used now under introducing first.
Due to using TFT, therefore also known as TFT thin film transistor monitor.TFT effect is the device for each pixel of active control
Part, thus equivalent to devising a field effect transistor switch pipe on each pixel.Multiple TFT101 constitute tft array,

Pixel P (i, j) chargings are turned on it is necessary to handle and the corresponding switches 204 of P (i, j), and data are given to signal wire 205 by data wire 206,
So that signal wire 205 applies voltages to pixel P (i, j).After pixel P (i, j) is fully charged, switch 204 disconnects.It need to point out
Even if switch 204 disconnects, the electric charge in electric capacity is also preserved, the liquid between pixel electrode 201 and common electrode 202
Brilliant molecule continues have electric field action, and such pixel P (i, j) can be shinny always, until being applied in before next voltage, by the electricity
Electric charge in appearance is discharged.Data wire 206 controls the voltage of a row pixel, and the switch of which pixel is opened, and data wire 206 is just

Driving 501, because single SCOF drives, 501 port number is limited, and to reach the purpose normally shown, the pixel of same type is pressed
The reduction of the port number of SCOF drivings is tackled according to horizontally arranged mode, with the type of pixel all same of a line.
Because Tri-gate panels only have a SCOF driving 501, drives line is poor to centre and to the line length of left and right
Away from larger, the drives lines 510 of such as SCOF drivings 501 to leftmost pixel arrive the drives of intermediate pixel with driving SCOF drivings 501
The length difference of moving-wire 511 is away from larger, therefore impedance is different, can so cause the intermediate pixel 502 and leftmost pixel 503 of same a line
Receive the identical drivings that same SCOF driving 501 is sent after, be actually added in intermediate pixel 502 and leftmost pixel 503
On driving voltage be different, and then intermediate pixel 502 is different with the actual gray of leftmost pixel 503, colour cast occurs.

Driving voltage for setting voltage when, its brightness value with set brightness value differ larger, then the voltage applied in the first pixel
Value is revised as after offset voltage value by original setting magnitude of voltage, can make brightness value when lighting and the setting of the first pixel
Brightness value is equal.
It is noted that ideally, when the magnitude of voltage applied in the first pixel is offset voltage value, the first pixel
Brightness value when lighting is equal with setting brightness value, in practical operation, is influenceed by environment, processing technology, characterization processes, i.e.,
When making the magnitude of voltage applied in the first pixel for offset voltage value, brightness when the first pixel is lighted can not be with setting brightness
Value is essentially equal, but has certain error, in practical operation, as long as the error is allowable error generally acknowledged in the industry, all
The brightness value being considered as when the first pixel is lighted is equal with setting brightness value.
In addition, while to the first pixel output drive signal, in addition to：To the second pixel output the second driving letter
Number, so that brightness when the second pixel is lighted is setting brightness value, the value for the driving voltage that the second drive signal includes is with setting
Determine magnitude of voltage equal.That is, liquid crystal panel drive is respectively to the first pixel drive signal different with the transmission of the second pixel, energy
Enough so that the brightness value when lighting of the first pixel and the second pixel is equal, it can thus avoid producing colour cast problem as far as possible.
