Description
[technical field]
The utility model relates to a kind of liquid crystal indicator, particularly a kind of active matrix liquid crystal display devices.
[background technology]
As everyone knows, liquid crystal indicator is to make backlight penetrate the purpose that liquid crystal reaches display image by Control of Voltage, if use the driven liquid crystal of identical polar continuously, can make liquid crystal produce inertia, make the display quality variation, simultaneously crosstalking between each pixel also can influence the demonstration image quality, so driving voltage must change polarity in proper order with certain, promptly adopts the reversal of poles driving method.Usually, reversal of poles can be divided into frame inversion driving (Frame Inversion), line inversion driving (LineInversion) and some inversion driving (Dot Inversion).Three kinds of inversion driving can be with document turnover when each frame output, and difference is: the driving polarity of the neighbor of frame inversion driving in a frame picture is identical; The line inversion driving comprises row counter-rotating and row counter-rotating, and row are reversed in the driving polarity difference of adjacent column pixel in the frame picture, and row is reversed in the driving polarity difference of adjacent lines pixel; The driving polarity difference of some inversion driving neighbor in a frame picture.The advantage of some inversion driving mode is effectively reduced the crosstalk noise in level and the vertical signal, effectively reduces film flicker, and promotes image quality.But some inversion driving power consumption is bigger.
For solving the big problem of some inversion driving power consumption, a kind of prior art driving method adopts the row inversion driving mode can reach the effect of an inversion driving.See also Fig. 1, a kind of liquid crystal indicator 10 of prior art comprises a liquid crystal panel 12, be used to drive the scanner driver 14 of the sweep trace GL1～GLn on this liquid crystal panel 12, be used to drive the data driver 16 of the data line DL1～DLm+1 on this liquid crystal panel 12, the time controller 18 of difference gated sweep driver 14 and data driver 16, be positioned at a plurality of thin film transistor (TFT) TFT (Thin Film Transistor) 11 of sweep trace GL1～GLn and data line DL1～DLm+1 intersection, and a plurality of pixel cell 13.Each pixel cell 13 comprises a pixel electrode (figure do not show), a public electrode (figure does not show) and is sandwiched in liquid crystal molecule (figure does not show) between two electrodes.The pixel electrode of each pixel cell 13 links to each other with a data line with the one scan line by a thin film transistor (TFT) TFT11.The a plurality of TFT 11 that are connected with each data line are alternately distributed the both sides in this data line.That is, (GL5...) continuous TFT 11 is positioned at the side of data line DL1～DLm+1 for GL1, GL3, and (GL6...) continuous TFT 11 is positioned at the opposite side of data line DL1～DLm+1 for GL2, GL4 with the even number line sweep trace with the odd line interlace line.
The data-signal that this scanner driver 14 provides scans each horizontal scanning line GL1～GLn successively, has only a horizontal scanning line to be scanned each time.When a horizontal scanning line was scanned, the TFT of delegation 11 that is connected with this horizontal scanning line that is scanned was unlocked.At this moment, data driver 16 is applied to a plurality of pixel electrodes that with this row TFT 11 are connected by data line DL1～DLm+1 with this row TFT11 that is in opening according to the gray scale voltage that image video signal produces.Because be applied in a stable reference voltage on all public electrodes usually, for example zero volt.Therefore be applied in one-row pixels unit 13 display image under the driving of gray scale voltage of gray scale voltage.
This data driver 16 adopts row inversion driving mode driving data lines DL1～DLm+1.As shown in FIG., during first frame scan, the vision signal that data driver 16 will have positive polarity offers and odd column data line (DL1, DL3, the pixel cell 13 that DL5...) is connected; The vision signal that data driver 16 will have negative polarity offers and even column data line (DL2, DL4, the pixel cell 13 that DL6...) is connected.Then, during second frame scan (figure does not show), data driver 16 is with the reversal of poles of vision signal, and the vision signal that therefore has negative polarity offers and odd column data line (DL2, DL4, the pixel cell 13 that DL6...) is connected; Vision signal with positive polarity offers and even column data line (DL3, the pixel cell 13 that DL5...) is connected.Therefore data driver 16 drives the type of drive of the pixel cell 13 realization point counter-rotatings of liquid crystal indicator.
Though above-mentioned improvement type of drive can solve the big problem of power consumption, but its pixel electrode is the vertical bar shape, and pixel is a rectangle, and therefore no overlapping part between the neighbor makes display device poor effect aspect display color.
