Description
Technical field
The present invention relates to a kind of driving method of liquid crystal indicator, relate in particular to and a kind ofly can solve green adhering to and cross-interference issue, and alleviate the driving method of the liquid crystal indicator of flicker.
Background technology
Figure 1 shows that the driving circuit calcspar of known tft liquid crystal display module.As shown in Figure 1, tft liquid crystal display module mainly comprises: and display panels (LCD panel), source electrode driver (Source Driver, SD), gate drivers (Gate Driver), time schedule controller (Tcon) and grayscale voltage generator (Gray Voltage Generator).The signal that sends LCD MODULE to comprises: R, G, B are the displayed image signals; DE is an enable signal; MCLK is a clock signal; Vsync, Hsync are respectively vertical synchronizing signal and horizontal-drive signal.Time schedule controller sends the signals such as polarity inversion signal POL, latch signal TP, row start signal STV, row clock signal CPV and output enable signal OE of start of line signal STH, positive phase to source electrode driver and gate drivers respectively, thereby display data is sent to the LCD panel.
In the industry cycle the liquid crystal display mode of Sheng Chaning is determined, and along with panel resolution specification difference, its timing control signal is also complicated, and time schedule controller is built in liquid crystal display mode certainly in may not being, but is decided in its sole discretion by downstream manufacturers.
The basic video picture unit of LCD panel is a sub-pixel, and this sub-pixel has capacity effect in panel construction, if on both sides in addition enough driving voltages will show that and this two voltage one is common voltage, another is a data line voltage.Because the sub-pixel of LCD panel has capacity effect, so if the voltage that is added on the electric capacity two ends is nonreversible, then the sub-pixel of Xian Shiing is charged for a long time by same voltage, this will accumulate certain quantity of electric charge for a long time between electrode, it is produced harmful effect, and serious meeting causes the liquid crystal polarization and the liquid crystal of this sub-pixel was lost efficacy, and slight influence also will make some background colors that show of LCD panel exist, and color contrast also can descend, and this can be more serious in high-resolution LCD panel.In order to reduce flicker, the voltage signal of driven element pixel need reverse at set intervals, and also need reverse between odd-numbered frame and the even frame simultaneously.
In liquid crystal indicator, time schedule controller offers source electrode driver and the various drive signals of gate drivers, and wherein the polarity inversion signal POL of positive phase is one-period property signal and is the time reference benchmark with start of line signal STH.In addition, press tft liquid crystal display control signal specification, the conversion of the high-low level of the polarity inversion signal POL of positive phase must be expert at valid in the specific time range after the start signal STH.
When Fig. 2 is odd-numbered frame, the synoptic diagram of corresponding relation between the polarity of voltage of the polarity inversion signal POL of positive phase and each sub-pixel of LCD panel.Only schematically listed the polarity of voltage distribution situation of each sub-pixel that source electrode driver drove among the figure.As shown in Figure 2, after having applied the polarity inversion signal POL of positive phase, the polarity of voltage of all adjacent subpixels all is positive and negative in twos opposite state.Wherein, "+" expression is a positive voltage with respect to common voltage, and "-" expression is a negative voltage with respect to common voltage.
When Fig. 3 is even frame, the synoptic diagram of corresponding relation between the polarity of voltage of the polarity inversion signal POL of minus phase and each sub-pixel of LCD panel.Still only schematically listed the polarity of voltage distribution situation of each sub-pixel that source electrode driver drove among the figure.As shown in Figure 3, after having applied the polarity inversion signal POL of minus phase, the polarity of voltage of all adjacent subpixels all is positive and negative in twos opposite state, and the polarity of voltage of all sub-pixels is all positive and negative opposite just with its situation when the odd-numbered frame.
When showing some special frames in twisted nematic type type (TN type) LCD panel, the general green phenomenon of picture color can take place, promptly so-called green adhering to; When the display window picture, the different of the color of the window left and right sides and other place can be taken place, promptly so-called lateral cross talk.
Because the existence of stray capacitance between signal wire and the common voltage COM, can cause common voltage COM fluctuation of generating period along with the output of each row signal line voltage, as shown in Figure 4, thereby cause the seal making alive of G sub-pixel less than normal, the general green phenomenon of picture color occurs.Simultaneously, estimate under the picture, also can cause flicker in flicker.
