Description
Technical field
The present invention relates to display technique, particularly a kind of bearing calibration of flicker of display panel, means for correcting.
Background technology
Liquid crystal indicator (LiquidCrystalDisplay, LCD) possesses the plurality of advantages such as frivolous, energy-conservation, radiationless, has therefore replaced traditional cathode-ray tube (CRT) (CRT) display gradually.Current liquid crystal display is widely used in the electronic equipments such as HD digital TV, desk-top computer, personal digital assistant (PDA), notebook computer, mobile phone, digital camera.
With thin film transistor (TFT) (ThinFilmTransistor, TFT) liquid crystal indicator is example, it comprises: display panels and driving circuit, wherein, display panels comprises multi-strip scanning line and a plurality of data lines, and adjacent two sweep traces and adjacent two data lines intersect to form a pixel cell, each pixel cell at least comprises a TFT.Driving circuit comprises gate driver circuit (gatedrivecircuit) and source electrode drive circuit (sourcedrivecircuit).Along with the cost degradation pursuit of the producer to liquid crystal indicator and the raising of manufacturing process, originally the glass substrate that the driving circuit integrated chip be arranged at beyond display panels is arranged at display panels becomes possibility, such as, grid-driving integrated circuit is arranged at array base palte (GateICinArray, GIA) upper thus simplify the manufacture process of liquid crystal indicator, and reduce production cost.
The basic functional principle of display panels and driving circuit is: gate driver circuit is by sending gate drive signal with pulling up transistor to sweep trace of being electrically connected of sweep trace, sequentially the TFT of every a line is opened, then the pixel cell of a full line is charged to voltage required separately, to show different GTGs to the data-signal that data line is sent by source electrode drive circuit simultaneously.Namely first to be pulled up transistor by it by the gate driver circuit of the first row and the thin film transistor (TFT) of the first row opened, then charged by the pixel cell of source electrode drive circuit to the first row.When the pixel cell of the first row is charged, this row thin film transistor (TFT) just cuts out by gate driver circuit, then the gate driver circuit of the second row is pulled up transistor by it and to be opened by thin film transistor (TFT) of the second row, then carries out discharge and recharge by source electrode drive circuit to the pixel cell of the second row.So sequentially go down, when the pixel cell of substituting the bad for the good last column, just charge from the first row again.
Electrically dissociate because liquid crystal molecule can produce along with long bias voltage, therefore the type of drive of general liquid crystal indicator drives for exchanging (AC), and namely data-signal changes back and forth between positive polarity and negative polarity.When voltage higher than public electrode of the voltage of pixel electrode, being just referred to as positive polarity, is that "+" represents; And when voltage lower than public electrode of the voltage of pixel electrode, be just referred to as negative polarity, represent with "-".At present, the interchange of liquid crystal indicator drives and can be divided into four kinds of modes, i.e. frame reversion driving, line inversion driving, row reversion drive and put reversion and drive.
Fig. 1 is the display frame schematic diagram under the some reversed polarity conversion regime of liquid crystal indicator when N frame.Fig. 2 is the display frame schematic diagram under the some reversed polarity conversion regime of liquid crystal indicator when N+1 frame.Point reversed polarity conversion regime refers to that the polarity of the voltage being applied to pixel electrode is opposite polarity by the pixel electrode that namely each pixel electrode is adjacent that repeats to reverse of pointwise, as shown in Figure 1, in N frame, just (+) voltage is applied to the odd line interlace line corresponding to odd column data line, all pixel electrodes of the even number line of even column data line, negative (-) voltage is applied to all pixel electrodes corresponding to the odd line interlace line of even column data line and the even number line sweep trace of odd column data line, and in N+1 frame, as shown in Figure 2, negative (-) voltage is applied to all pixel electrodes corresponding to the odd line interlace line of odd column data line and the even number line of even column data line, just (+) voltage is applied to all pixel electrodes corresponding to the odd line interlace line of even column data line and the even number line sweep trace of odd column data line.
For display panels, the best public electrode voltages that different GTGs is corresponding different, therefore, when arranging a certain public electrode voltages, the positive-negative polarity that can there is pixel electrode corresponding to some GTG is asymmetric, thus makes flicker (flicker) phenomenon that display panels can exist in various degree due to the positive-negative polarity asymmetrical voltage of the pixel electrode of the same position in adjacent two frames (namely brightness is different).
Therefore, be necessary to provide the technical scheme of improvement to overcome the above technical matters existed in prior art.
