As shown in Fig. 2, each column box is the column pixel electrode on scan line G, one end of every capacitor line Lc with Pixel electrode connection on scan line G, the other end extend to the electric field region of compensating line G ˊ, capacitor line Lc and scan line G It insulate between compensating line G ˊ, and also insulate between every capacitor line Lc.In addition, every two adjacent groups compensated scanning line 10, The capacitor line Lc of 20 ... N is also insulation.

Further, every group of compensated scanning line 10, the scan line G in 20 ... N and compensating line G ˊ are by the same scanning Driver is drawn.

In the present embodiment, compensating line G ˊ and scan line G setting are arranged in same layer, capacitor line Lc and scan line G in difference Layer, is provided with insulating materials between capacitor line Lc and compensating line G ˊ and scan line G, so that between capacitor line Lc and scan line G, And capacitor is respectively formed between capacitor line Lc and compensating line G ˊ.According to the volume of the capacitor between capacitor line Lc and scan line G and The volume of the capacitor of capacitor line Lc and compensating line G ˊ, using the capacitor between capacitor line Lc and scan line G as the first compensating electric capacity, The capacitor of capacitor line Lc and compensating line G ˊ are the second compensating electric capacity.Wherein, enabling the first compensating electric capacity is Cft, then the second compensating electric capacity For Cft+Cgs

At this point, the second scan line G2 starts input high level, 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 inputs low electricity Usually, since the input signal of compensating line G ˊ is low level, to the pixel voltage V of pixel electrode ApixelIt does not have an impact, 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, third 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 third scan line When input low level, since the input signal of compensating line G ˊ is still low level, to the pixel voltage V of pixel electrode ApixelStill not It has an impact, 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 When G4 input low level, a pulse period terminates, and the input signal of compensating line G ˊ becomes high level, at this time according to formula Δ V1 =(Von–Voff)·(Cgs+Cft)/(2Cgs+Cst+Clc+4Cft), the pixel voltage V on pixel electrode ApixelDecline Δ V1 again.

It 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 rises Δ V1 within a pulse period and decline time of Δ V1 Number is identical, and the number for rising Δ V2 and decline Δ V2 is also identical, and the time of a pulse period is only 7.7 μ s or so, then Make pixel electrode A pixel voltage V in a very short period of timepixelThe number 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.
