Description
Technical field
The present invention relates to a kind of LCD device array substrates and driving method, relate in particular to a kind of array base palte of thin-film transistor LCD device and the driving circuit on this array base palte is carried out method of driving.
Background technology
Thin-film transistor LCD device (Thin Film Transistor-Liquid CrystalDisplay is hereinafter to be referred as TFT-LCD) is one of present most popular flat-panel monitor.TFT-LCD generally comprises display panels, scan drive circuit and data drive circuit.Wherein, display panels comprises color membrane substrates and the tft array substrate that box is provided with, and is clipped in the liquid crystal layer between the two substrates, and scan drive circuit and data drive circuit link to each other with TFT on-off element on the array base palte respectively.Be illustrated in figure 1 as the array base-plate structure synoptic diagram on existing a kind of TFT-LCD, it comprises underlay substrate 1, the liquid crystal pixel electrodes 2 that is arranged on the underlay substrate 1, arranges with matrix form, be arranged on data line 3 and sweep trace 4 between liquid crystal pixel electrodes 2 ranks, data line 3 links to each other with data driving chip 8, sweep trace 4 links to each other with scanner driver 9, a common data line 3 corresponding 2, one sweep traces of control one row liquid crystal pixel electrodes, the 4 corresponding control delegation liquid crystal pixel electrodes 2 that connect that connect.Connect active electrode 5 on each liquid crystal pixel electrodes 2, corresponding each source electrode 5 all is provided with drain electrode 6, and drain electrode 6 is connected on the corresponding data line 3, is arranged with grid 7 at every pair of source electrode 5 and drain electrode 6, and grid 7 is connected on the corresponding scanning line 4.Source electrode 5, drain electrode 6 and grid 7 are promptly formed the TFT on-off element.
When array base palte was worked, data line was used for the video data signal of data driving chip (IC) is sent to the drain electrode of TFT on-off element, controls the voltage of liquid crystal pixel electrodes with this; Sweep trace is used for the scanning drive signal of scanner driver is sent to the grid of TFT on-off element, controls closing and opening of TFT on-off element with this.When liquid crystal indicator was worked, for a frame picture, data driving chip was transferred to drain electrode with video data signal by data line, and scanner driver is line by line to sweep trace input scan drive signal.When scanning drive signal is high level, can pass through gate turn-on source electrode and drain electrode, video data signal is transferred to liquid crystal pixel electrodes.Because be connected with common electric voltage in the public electrode that is oppositely arranged with liquid crystal pixel electrodes, so between liquid crystal pixel electrodes and public electrode, can form certain voltage.The change of this voltage swing can further change the transmitted light intensity size of the liquid crystal that is arranged between liquid crystal pixel electrodes and the public electrode, thereby realizes that image shows.In liquid crystal indicator, each liquid crystal pixel electrodes i.e. a liquid crystal display, usually be divided into three pixel electrodes of red, green, blue, the color film of corresponding color is set in the above, as red (R), green (G), blue (B) three primary colours, the data line that connects a liquid crystal pixel electrodes in fact generally has three, connects the voltage on three pixel electrodes of control red, green, blue respectively, promptly can realize colored the demonstration.
But the subject matter that exists in the above-mentioned technology is: the first, for TFT-LCD, the chip for driving of control Driver Circuit comprises scanning drive chip and data driver, all be absolutely necessary, and the cost of chip for driving occupies significant proportion in the TFT-LCD production cost, and data driving chip makes that the whole cost of existing TFT-LCD product is higher because its complicated texture ratio scanner driver is more expensive; Second, for preventing that liquid crystal pixel electrodes is aging, the technological means that prior art adopts usually is the video data signal of reversal data line input, be reverse signal voltage, for example the common electric voltage in the public electrode is set at steady state value 6V, and the video data signal of data line input is set at 0V～12V, then the magnitude of voltage between liquid crystal pixel electrodes and the public electrode can-6V～+ change between the 6V, make that the alternating voltage between liquid crystal pixel electrodes and the public electrode is changed to positive voltage and negative voltage.Voltage by setting video data signal can make the order of magnitude of positive voltage and negative voltage equate with respect to the intermediate value symmetry, thereby guarantees performance unanimity such as display brightness.But, because the data line on the LCD device array substrates, the source electrode of sweep trace and TFT on-off element, there is juxtaposition in drain electrode, so inevitably between each circuit and element, produced stray capacitance, between gate electrode opens and closes during conversion since the voltage at stray capacitance two ends undergo mutation, thereby produced a feed-trough voltage (Kickback), the polarity of this Kickback voltage is constant, so that liquid crystal pixel electrodes just, reverse voltage is behind the Kickback voltage that superposeed, just, the order of magnitude of negative voltage is asymmetric, thereby can cause the display quality deterioration, bright slightly and dark slightly picture appears significantly alternately, be scintillation, also ghost can occur, defectives such as cross-talk.
