According to the structure of the present embodiment display driver circuit, the voltage lost in capacitance compensation scan line is driven to the display
The process of coupling amount is illustrated.Now, due to increased compensating line and capacitor line, voltage is made to couple to pixel on pixel electrode
Voltage VpixelInfluence formula be：Δ V=(Voff–Von)·(Cgs+Cft)/(2Cgs+Cst+Clc+nCft), wherein VoffAnd VonIt is
The closing voltage and cut-in voltage of scan line, CgsIt is the parasitic capacitance of film transistor device, CstIt is storage capacitance, ClcIt is liquid
Brilliant electric capacity, wherein, ClcIt is the variable related to the GTG of liquid crystal panel, CftIt is the first compensation between capacitor line and scan line
Electric capacity, n is the quantity of the first compensating electric capacity formed between every capacitor line and scan line.
By taking first pixel electrode A of square frame in Fig. 2 as an example, the scan line in Fig. 2 is respectively defined as the first scan line
G1, the second scan line G2, three scan line G3 and the 4th scan line G4, and make first pixel electrode A connection of square frame in Fig. 2
Capacitor line Lc11 by positioned at its connection pixel electrode A corresponding first scan line G1 and compensating line G ˊ between other sweep
Line G2, G3, G4 are retouched, then the first compensating electric capacity quantity C for being formed between this capacitor line Lc11 and scan line G1, G2, G3, G4ft
Quantity for 4 (if it is worth noting that, capacitor line Lc11 of its connection bypasses the corresponding scan lines of pixel electrode A of its connection
Other scan lines G2, G3, G4 between G1 and compensating line G ˊ, then this capacitor line Lc11 only with the first scan line G1 formed first
Compensating electric capacity Cft, then n is for 1).Now, pixel voltage V on pixel electrode ApixelInfluence formula be：Δ V=(Voff–
Von)·(Cgs+Cft)/(2Cgs+Cst+Clc+4Cft)。
With reference to Fig. 3, Fig. 3 is the time diagram of the input signal of display driver circuit of the present invention.With reference to Fig. 2 and Fig. 3,
In the t1-t2 time periods, when the input signal of the first scan line G1 is high level, the input signal of compensating line G ˊ is low level,
Pixel electrode A is opened, and pixel electrode A is charged normal.When the input signal of the first scan line G1 is low level, according to formula
Δ V1=(Voff–Von)·(Cgs+Cft)/(2Cgs+Cst+Clc+4Cft), the pixel voltage V on pixel electrode ApixelDecline Δ V1.
Now, the second scan line G2 starts input high level, and pixel electrode is opened, according to formula Δ V2=(Von–Voff)·
Cft/(2Cgs+Cst+Clc+4Cft), the pixel voltage V on pixel electrode ApixelRise Δ V2.When the second scan line G2 is input into low electricity
Usually, because the input signal of compensating line G ˊ is low level, to the pixel voltage V of pixel electrode ApixelInfluence is not produced, then root
According to formula Δ V2=(Voff–Von)·Cft/(2Cgs+Cst+Clc+4Cft), the pixel voltage V on pixel electrode ApixelΔ V2 has dropped.
Then, three scan line G3 starts input high level, and pixel electrode A is again turned on, according to formula Δ V2=(Von–
Voff)·Cft/(2Cgs+Cst+Clc+4Cft), the pixel voltage V on pixel electrode ApixelRise Δ V2 again.When three scan line
During input low level, because the input signal of compensating line G ˊ is still low level, to the pixel voltage V of pixel electrode ApixelStill not
Influence is produced, then according to formula Δ V2=(Voff–Von)·Cft/(2Cgs+Cst+Clc+4Cft), the pixel voltage on pixel electrode A
VpixelDecline Δ V2 again.
Then, the 4th scan line G4 starts input high level, and pixel electrode A is again turned on, according to formula Δ V2=(Von–
Voff)·Cft/(2Cgs+Cst+Clc+4Cft), the pixel voltage V on pixel electrode ApixelRise Δ V2 again；When the 4th scan line
During G4 input low levels, a pulse period terminates, and the input signal of compensating line G ˊ is changed into high level, now according to formula Δ V1
=(Von–Voff)·(Cgs+Cft)/(2Cgs+Cst+Clc+4Cft), the pixel voltage V on pixel electrode ApixelDecline Δ V1 again.
Be can be seen that within a pulse period according to above-mentioned analysis, the pixel voltage V on pixel electrode ApixelDecline
Δ V1 and Δ V2, equally also rises Δ V1 and Δ V2, and rise Δ V1 within the pulse period and decline Δ V1 time
Number is identical, and it is also identical with the number of times for declining Δ V2 to rise Δ V2, and the time of a pulse period is only 7.7 μ s or so, then
Make pixel electrode A pixel voltage V in very short timepixelThe number of times that raising and lowering occurs is identical, and raising and lowering
Variable quantity is also identical, and then realizes the compensation to the voltage coupling amount lost in scan line.
