Even.
Specifically, in above-mentioned common electric voltage compensation circuit provided in an embodiment of the present invention, as shown in Fig. 2 detection module can
To be realized by time schedule controller, display device can also include front end system.Front end system can working as display panel
The corresponding data is activation of preceding display picture Pattern gives time schedule controller Tcon, Tcon detection pattern analysis common electric voltages
The fluctuation situation of Vcom, once detecting that this pattern causes Vcom that big ups and downs occur, then the GPIO port of Tcon can be given
Vcom compensation circuits send enable signal (the specific signal that enables can be high level), open Vcom compensating modules to display surface
Plate is compensated so that in display panel Vcom keep stabilization, if the Pattern for detecting do not cause Vcom fluctuate or
Vcom fluctuations less (not less than predetermined threshold value), then do not send enable signal (sending low level signal), Vcom compensating modules
It is not turned on, saves power consumption.
Specifically, as shown in Fig. 2 when Vcom compensation circuits are opened, the public voltage signal Vcom_In of display panel is input into
To the normal phase input end of operational amplifier OP, the common electric voltage feedback signal Vcom_ of the currently displaying picture of display panel
Feedback is input to the inverting input of operational amplifier OP, then by output end after operational amplifier OP is processed
The common electric voltage thermal compensation signal of Vcom OUT is input to display panel again, so as to weaken display panel common electric voltage ripple in itself
It is dynamic.As shown in figure 3, Vcom_In produces big ups and downs, the common electric voltage value of feedback Vcom_Feedback according to display panel leads to
The treatment of operational amplifier is crossed, the thermal compensation signal fluctuation of final output end Vcom OUT outputs is substantially improved.

Shown in oscillogram, wherein, the 1st, 2,3 row correspondences first group of RGB, the 4th, 5,6 row second group of RGB of correspondence, the vertical line m left sides represent negative
Polarity, vertical line m the right representing positive polarity.The G of the polar signal being input into from each sub-pix, first row R pixels and secondary series
The signal polarity of pixel input is conversely, reach balanced polarities；The signal polarity that tertial B pixels are input into the R pixels of the 4th row
Balance can not be reached, so as to cause common electric voltage Vcom to produce fluctuation as shown in fig. 4 a.Each sub-pix input of wherein the first frame
Signal in, for just, the signal polarity of the 4th row R pixels is negative and more than the 3rd row B pixels to the signal polarity of the 3rd row B pixels
Signal, thus the first frame public voltage signal Vcom to negative polarity direction fluctuate；In the signal of each sub-pix input of the second frame,
3rd row B pixels signal polarity be it is negative, the 4th arrange R pixels signal polarity be just and less than the 3rd arrange B pixels signal, therefore
The public voltage signal Vcom of the second frame still fluctuates to negative polarity direction, due to identical with the signal fluctuation direction of previous frame,
Therefore public voltage signal Vcom polarity keeps the fluctuation of previous frame polarity；The rest may be inferred, the 3rd frame, the 4th frame signal wave emotionally
As shown in fig. 4 a, and the corresponding common electric voltage wave principle of display picture as shown in Fig. 4 b- Fig. 4 d is identical for condition, does not make herein in detail
State.

Under display picture shown in Fig. 4 a, Fig. 4 b and Fig. 4 d, common electric voltage Vcom fluctuations are larger, and it is several that time schedule controller Tcon detects this
During individual display picture pattern, after the fluctuation situation of analysis common electric voltage Vcom (Vcom fluctuations are more than predetermined threshold value), can send
Enable signal and open common electric voltage Vcom compensation, so as to improve picture quality；And it is public under display picture as illustrated in fig. 4 c
Voltage Vcom fluctuates smaller (almost not having), and time schedule controller Tcon does not send enable signal, and Vcom compensating modules are not turned on, i.e.,
In the case of display picture quality is out of question, the power consumption of common electric voltage Vcom compensation circuits is reduced.
