Specific embodiment
The explanation of following embodiment is, with reference to additional schema, to be used to illustrate the particular implementation that the present invention may be used to implement
Example.The direction term that the present invention is previously mentioned, for example " on ", D score, "front", "rear", "left", "right", " interior ", " outward ", " side "
Deng being only the direction with reference to annexed drawings.Therefore, the direction term for using is to illustrate and understand the present invention, and is not used to
The limitation present invention.
In figure, the similar unit of structure is represented with identical label.
Refer to the structural representation of Fig. 1 and the preferred embodiment that Fig. 2, Fig. 1 are liquid crystal display panel of the invention；Fig. 2
It is the scanning drive chip group and the structural representation of comparing unit of the preferred embodiment of liquid crystal display panel of the invention.The liquid
LCD panel 10 includes data wire 11, scan line 12 and the pixel cell being staggered to form by data wire 11 and scan line 12
13, wherein liquid crystal display panel 10 also includes data driving chip 14, at least two scanning drive chip groups 15 and compares single
Unit.Wherein scanning drive chip group includes at least two scanning drive chips, and data driving chip 14 is connected with data wire 11, uses
In giving the input data signal of data wire 11；The scanning drive chip of scanning drive chip group 15 is connected with corresponding scan line 12,
For being input into scanning signal to scan line 12；Comparing unit (not shown in figure 1) is connected with two scanning drive chips respectively, uses
In the scanning signal exported according to one scan driving chip, the scanning signal to the output of another scanning drive chip carries out signal benefit
Repay, setting value is less than with the difference of the scanning signal for two scanning drive chips is exported.In order to preferably compensate behaviour
Make, the scanning signal of the comparing unit scanning drive chip output later to output scanning signal carries out signal compensation.Certainly this
In scanning drive chip group may also comprise more than two scanning drive chips, comparing unit is driven by the scanning to combination of two
Dynamic chip carries out signal compensation, so that the difference of the scanning signal pulse of all of scanning drive chip output is smaller.
Fig. 2 is refer to, wherein scanning drive chip group 15 includes the output scanning signal He of scanning drive chip 151 earlier
The later scanning drive chip 152 of output scanning signal.The comparing unit includes comparison amplifier 161 and signal output interface
162.The output scanning signal first input end that scanning drive chip 151 passes through delayer 163 and comparison amplifier 161 earlier
Connection, the later scanning drive chip 152 of output scanning signal respectively with second input and signal of comparison amplifier 161
Output interface 162 is connected, and the output end of comparison amplifier 161 is connected with signal output interface 162.
When the liquid crystal display panel 10 of this preferred embodiment is used, data driving chip 14 is by data wire 11 to corresponding
The input data signal of pixel cell 13, scanning drive chip is input into scanning letter by scan line 12 to corresponding pixel cell 13
Number.Because the output pulse of the scanning signal of different scanning driving chip has differences, comparing unit here is scanned to output
The scanning signal of the later output of scanning drive chip 152 of signal carries out signal compensation.Specifically as shown in Fig. 2 wherein scanning
Driving chip 151 exports scanning signal prior to scanning drive chip 152.
Scanning drive chip 151 exports scanning signal first, and be input into corresponding scanning signal to picture line by line by scan line 12
Plain unit 13 carries out display driving；The scanning signal of the output of scanning drive chip 151 simultaneously is input into comparing by delayer 163
The first input end of amplifier 161, to cause that the scanning signal that can be subsequently produced with scanning drive chip 152 carries out contrast behaviour
Make.
The subsequent output of scanning drive chip 152 scanning signal, the scanning signal is input into second defeated to comparison amplifier 161
Enter end；Comparison amplifier 161 is contrasted according to the scanning signal of first input end, the scanning signal to the second input, from
And calibration factor is generated, and export to signal output interface 162 calibration factor from output end.Such as the scanning of first input end
More than the scanning signal of the second input, then the calibration factor for comparing amplification 161 devices generation is just, such as first input end to signal
Less than the scanning signal of the second input, then the calibration factor of the generation of comparison amplifier 161 is negative to scanning signal.
Then signal output interface 162 receives the calibration factor of the output end output of comparison amplifier 161, and synchronous signal is defeated
Outgoing interface 162 receives the output scanning signal of scanning drive chip 152, and signal output interface 162 is according to the calibration factor to scanning
The scanning signal of the output of driving chip 152 is calibrated, and such as calibration factor is just, then the output of scanning drive chip 152 to be swept
Retouch signal and be amplified treatment, such as calibration factor is negative, then the scanning signal to the output of scanning drive chip 152 is carried out at diminution
Reason；So that the difference of the scanning signal of the output of scanning drive chip 151 and the scanning signal of the output of scanning drive chip 152 can be with
Less than setting value, the setting value can be set according to the requirement of user.Last signal output interface 162 is by the scanning after calibration
Signal is exported to corresponding scan line 12 line by line.
Due to the scanning signal that comparing unit is exported according to scanning drive chip 151, to the output of scanning drive chip 152
Scanning signal carries out the positive compensation or negative compensation of signal, so that scanning drive chip 151 and scanning drive chip 152 are exported
The difference of scanning signal can be less than setting value.
Specifically as shown in Figure 3 A and Figure 3 B, Fig. 3 A are the difference before the comparing unit calibration of liquid crystal display panel of the invention
The oscillogram of the scanning signal of scanning drive chip；Fig. 3 B be liquid crystal display panel of the invention comparing unit calibration after not
With the oscillogram of the scanning signal of scanning drive chip.Different scanning driving chip before Fig. 3 A, comparing unit calibration
The scanning signal of (scanning drive chip 301A and scanning drive chip 302A) with larger amplitude difference, and in Fig. 3 B,
The scanning letter of the different scanning driving chip (scanning drive chip 301B and scanning drive chip 302B) after comparing unit calibration
Number amplitude it is essentially identical, so as to liquid crystal display device caused by the difference of the scanning signal for avoiding different driving chip
Display is bad.
Liquid crystal display panel of the invention and liquid crystal display device are by setting comparing unit so that different driving chip
Scanning signal output pulse differences are smaller, so as to improve the display effect of liquid crystal display device.
The present invention also provides a kind of liquid crystal display device, and the liquid crystal display device includes backlight and LCD
Plate.The liquid crystal display panel includes data wire, scan line, pixel cell, data driving chip, scanning drive chip group and ratio
Compared with unit.Pixel cell is staggered to form by data wire and scan line；Data driving chip is connected with data wire, for data wire
Input data signal；Comparing unit is connected with two scanning drive chips respectively, for what is exported according to one scan driving chip
Scanning signal, the scanning signal to the output of another scanning drive chip carries out signal compensation, to cause two scanning drive chips
The difference of the scanning signal of output is less than setting value.
Preferably, the scanning signal of scanning drive chip output later to output scanning signal carries out signal compensation.
Preferably, the comparing unit includes comparison amplifier, and scanning drive chip passes through to prolong output scanning signal earlier
When device be connected with the first input end of comparison amplifier；The output later scanning drive chip of scanning signal, puts with comparing respectively
