Description
Technical field
The present invention relates to display technique field, particularly a kind of formation method of display panel, display panel and display device.
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 frame reversed polarity conversion regime of liquid crystal indicator.Wherein, frame reversed polarity conversion regime refers to that the polarity of the voltage being applied to pixel electrode is repeated reversion by frame by frame.As shown in Figure 1, just (+) voltage is applied to all pixel electrodes in the first frame, and negative (-) voltage is applied to all pixel electrodes in the second frame.
Fig. 2 is the row reversed polarity conversion regime of liquid crystal indicator.Wherein, row reversed polarity conversion regime refer to the polarity of the voltage being applied to pixel electrode by line by line repeat reversion.As shown in Figure 2, just (+) voltage is applied to all pixel electrodes corresponding to odd line interlace line, negative (-) voltage is applied to all pixel electrodes corresponding to even number line sweep trace, and in the next frame, negative (-) voltage is applied to all pixel electrodes corresponding to odd line interlace line, and just (+) voltage is applied to all pixel electrodes corresponding to even number line sweep trace.
Fig. 3 is the row reversed polarity conversion regime of liquid crystal indicator.Wherein, row reversed polarity conversion regime refer to the polarity of the voltage being applied to pixel electrode by by column repeat reversion.As shown in Figure 2, just (+) voltage is applied to all pixel electrodes corresponding to odd column data line, negative (-) voltage is applied to all pixel electrodes corresponding to even column data line, and in the next frame, negative (-) voltage is applied to all pixel electrodes corresponding to odd column data line, and just (+) voltage is applied to all pixel electrodes corresponding to even column data line.
Fig. 4 is the some reversed polarity conversion regime of liquid crystal indicator.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 4, just (+) 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, 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 the next frame, 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.
Wherein, the reversal of poles mode of some reversion because seldom there is scintillation (Flicker) and crosstalk phenomenon (Crosstalk), display effect the best, and becomes main way.But, under identical common electric voltage, some reversion need the variation frequency of data line output voltage and changing voltage size maximum, the power consumption therefore putting reversion is maximum.
Based on the feature of above-mentioned each inverting method, in prior art, the type of drive of row reversion or row reversion usually can be adopted to realize a reversal of poles mode for reversion, to reduce the power consumption of reversal of poles.Fig. 5 is the part-structure schematic diagram of the display panels of prior art.Fig. 6 is the equivalent circuit diagram of display panels as shown in Figure 5.As shown in Figures 5 and 6, a display panels that can to realize some reversion by row reversion comprises: a plurality of data lines 11 and multi-strip scanning line 12, and multiple pixel cells that a plurality of data lines 11 and multi-strip scanning line 12 intersect to form.Each pixel cell includes TFT20 and pixel electrode 21, and the grid of each TFT20 is electrically connected with the sweep trace 12 below pixel electrode 21, that is, the partial metal layers below each pixel electrode 21 needs to be connected with sweep trace 12 as the grid of TFT20.The source electrode of each TFT20 is electrically connected with the pixel electrode 21 in the pixel cell at its place.Wherein, for arbitrary neighborhood two row pixel cell, the drain electrode of the TFT20 in one-row pixels unit is electrically connected with the data line 11 on the left of it, and the drain electrode of the TFT20 in another row pixel cell is electrically connected with the data line 11 on the right side of it.
But the metal level below each pixel electrode 21 of above-mentioned display panels need be connected with sweep trace 12 as the grid of TFT20, in order to ensure the normal formation of each TFT, metal level as the grid of TFT20 below each pixel electrode 21 need ensure certain width, but due to the restriction of processing procedure, as shown in Figure 4, the width of sweep trace 12 is identical with the width of the gate metal layer of TFT20, thus the aperture opening ratio causing above-mentioned display panels is low.
