The present invention relates to a kind of technical field of liquid crystal display, particularly a kind of multi-domain vertical alignment-type liquid crystal display panel and liquid crystal display with wide viewing angle.
Background technology
Liquid crystal display (Liquid Crystal Display, LCD) have the advantages such as light, thin, low power consumption, be widely used in the modernized information equipments such as computing machine, mobile phone and personal digital assistant (Personal Digital Assistant, PDA).At present, usually require liquid crystal display to have high-contrast, high brightness, high color saturation, the quick characteristic such as response and wide viewing angle on the market.
In order to realize wide viewing angle, also developed multiple different display in the prior art, as: twisted nematic (Twisted Nematic, TN) liquid crystal display adds view film, copline switch type (In-plane switching, IPS) liquid crystal display, fringe field switch type (Fringe FieldSwitching, FFS) liquid crystal display and multi-domain perpendicular alignment-type (Multi-domain VerticalAlignment, MVA) liquid crystal display etc.
In order to reach better display effect, existing liquid crystal display is a plurality of sub-pixels with a pixel segmentation often, utilizes on-off element to control respectively each sub-pixel, to realize more excellent display effect.
Fig. 1 is the part-structure synoptic diagram of existing a kind of multi-domain perpendicular alignment-type liquid crystal display, and liquid crystal display comprises thin-film transistor array base-plate, colored filter substrate and is clipped in liquid crystal layer between the two substrates.In order clearly to describe this structure, omitted colored filter substrate among the figure.As shown in Figure 1, this liquid crystal display comprises sweep trace 110 (comprising the Gn shown in the figure, Gn+1, Gn+2, Gn+3); Data line 120 (comprising the Dn shown in the figure, Dn+1, Dn+2, Dn+3, Dn+4, Dn+5) with described sweep trace cross arrangement; Per two adjacent scanning lines 110 and per two adjacent data lines 120 mutually intersection surround a pixel region 100, described pixel region 100 comprises the first pixel electrode SP1 and the second pixel electrode SP2 of to each other electricity isolation, the first film transistor T 1 that links to each other with described the first pixel electrode SP1, be used for this first pixel electrode of control SP1, and the second thin film transistor (TFT) T2 that links to each other with described the second pixel electrode SP2, be used for this second pixel electrode of control SP2.
The grid of the first film transistor T 1 and the second thin film transistor (TFT) T2 is electrically connected to respectively different sweep traces, is controlled its unlatching or is closed by the sweep signal that transmits on the sweep trace; Source electrode is electrically connected to respectively the different data line of polarity, in order to the signal on the respective data lines is sent to the sub-pixel of correspondence when it is opened.
Be positioned at the pixel region 100 of the capable n row of n in Fig. 1 as example, its first pixel electrode SP1 is by 1 control of the first film transistor T, and the grid of this first film transistor T 1 electrically is electrically connected to sweep trace Gn+1, and source electrode electrically is electrically connected to data line Dn; The second pixel electrode SP2 is controlled by the second thin film transistor (TFT) T2, and the grid of this second thin film transistor (TFT) T2 is electrically connected to sweep trace Gn, and source electrode is electrically connected to data line Dn+1.

Certainly, the present invention is not limited thereto, the first pixel electrode 201 of the present invention can only have at least one first occlusal area 2011 and not have the first extension occlusal area 2012, the second pixel electrode 202 can only have at least one second occlusal area 2021 and not have the second extension occlusal area 2022, in this embodiment, the first occlusal area 2011 and the second occlusal area 2021 are staggered, thereby, the first occlusal area 2011 extends into the second pixel electrode 202, the second occlusal areas 2021 and extends into the first pixel electrode 201.For this embodiment, can reach equally the effect of the embodiment of the invention.Do not repeat them here.Several embodiment that this kind situation is equally applicable to the following describes.The following examples only have at least one first occlusal area 2011 with the first pixel electrode 201 and at least one the first extension occlusal area 2012, the second pixel electrode 202 has at least one second occlusal area 2021 and at least one second extension occlusal area 2022 describes for example.
In the present embodiment, have a sweep trace between the adjacent two row pixel regions 200, have two data lines 220 between the adjacent two row pixel regions 200, namely be called the 2D1G structure.For example, have sweep trace G2 between the first row pixel region 200 and the second row pixel region 200, have data line D2 and data line D3 between first row pixel region 200 and the secondary series pixel region 200.
In the present embodiment, the grid of the first film transistor 203 and the second thin film transistor (TFT) 204 is electrically connected to respectively different sweep traces, by the unlatching of the corresponding thin film transistor (TFT) that connects of the sweep signal that transmits on sweep trace control or close; The source electrode of the first film transistor 203 and the second thin film transistor (TFT) 204 is electrically connected to respectively different data lines, so that the signal on the data line that when it is opened correspondence is connected is sent on the corresponding sub-pixel.For example, take the pixel region 200 that is positioned at the first row first row as example, the grid of the first film transistor 203 is electrically connected sweep trace G2, source electrode is electrically connected data line D1, drain electrode is electrically connected the first pixel electrode 201, and the grid of the second thin film transistor (TFT) 204 is electrically connected sweep trace G1, and source electrode is electrically connected data line D2, and drain electrode is electrically connected the second pixel electrode 202.
In the present embodiment, the odd data line in the described data line 220 connects the first pixel electrode 201 in the same row pixel region 200, and the even data line connects the second pixel electrode 202 in the same row pixel region 200.Single scan line in the described sweep trace 210 connects the first pixel electrode 201 of the odd-numbered line in the adjacent two row pixel regions 200 and the second pixel electrode 202 of even number line.
The first pixel electrode 201 can have identical polarity or different polarity with the second pixel electrode 202, and the preferred embodiments of the present invention are that the first pixel electrode 201 has different polarity with the second pixel electrode 202.Can drive by row counter-rotatings (Column Inversion) driving or some counter-rotating (Dot Inversion) and realize that the first pixel electrode 201 has different polarity with the second pixel electrode 202.
The below carries out the labor explanation as an example of row counter-rotatings drives and adjacent two data line D1, D2 and adjacent two sweep trace G1, G2 surround pixel region 200 example to the embodiment of the invention.
In same frame, adjacent two data line D1, D2 supply with respectively the voltage of opposed polarity, and for example, the voltage of data line D1 supply is positive polarity, and the voltage of data line D2 supply is negative polarity.When the scanning pulse signal on the sweep trace G1 is high voltage, the second thin film transistor (TFT) 204 that is electrically connected with sweep trace G1 is opened, reverse voltage on the data line D2 arrives on the second pixel electrode 202 by source electrode and the drain electrode of the second thin film transistor (TFT) 204, be used for to 202 chargings of the second pixel electrode, therefore, the pixel voltage that the second pixel electrode 202 has negative polarity, afterwards, scanning pulse signal on the sweep trace G1 is low-voltage from high-voltage variable, and this second pixel electrode 202 keeps the pixel voltage of this negative polarity until next frame comes interim; At this moment, scanning pulse signal on the sweep trace G2 transfers high voltage to by low-voltage, the first film transistor 203 that is electrically connected with sweep trace G2 is opened, positive polarity voltage on the data line D1 arrives on the first pixel electrode 201 by source electrode and the drain electrode of the first film transistor 203, be used for to 201 chargings of the first pixel electrode, therefore, the pixel voltage that the first pixel electrode 202 has positive polarity, afterwards, scanning pulse signal on the sweep trace G2 is low-voltage from high-voltage variable, and this first pixel electrode 201 keeps the pixel voltage of this positive polarity until next frame comes interim.Scan successively so, from top to bottom all bar sweep traces.Therefore, in same frame, the first pixel electrode 201 and the second pixel electrode 202 have respectively opposite polarity.First of the first pixel electrode 201 extends occlusal area 2012 and also has positive polarity, and second of the second pixel electrode 202 extends occlusal area 2022 and also has negative polarity.
Because the first pixel electrode 201 and the second pixel electrode 202 be indentation respectively, and the first pixel electrode 201 and the second pixel electrode 202 are engaged, therefore, first the extending the second pixel electrode 202 that occlusal area 2012 had respectively negative polarity and surround of the first pixel electrode 201 with positive polarity, in a preferred embodiment of the invention, the first extension occlusal area 2012 and second extends occlusal area 2022 and is arranged side by side, the first the second pixel electrode 202 that is all had up and down negative polarity that extends occlusal area 2012 with positive polarity surrounds, therefore, the polarity with adjacent the second pixel electrode 202 is opposite respectively can to regard polarity that first of the first pixel electrode 201 extends occlusal area 2012 as.Has opening 108 between the first pixel electrode 201 and the second pixel electrode 202, therefore, extend between occlusal area 2012 and adjacent the second pixel electrode 202 first and also to have opening, because under the electric field action that the first voltage that extends positive-negative polarity between occlusal area 2012 and adjacent the second pixel electrode 202 forms, can extend liquid crystal molecule in the occlusal area 2012 and topple over and in pixel region 200, form a plurality of territories towards different directions respectively in zone up and down so that have first of positive polarity.
In like manner, second the extending the first pixel electrode 201 that occlusal area 2022 had respectively positive polarity and surround of the second pixel electrode 202 with negative polarity, in a preferred embodiment of the invention, the second the first pixel electrode 201 that is all had up and down positive polarity that extends occlusal area 2022 with negative polarity surrounds, because under the electric field action that the second voltage that extends negative positive polarity between occlusal area 2022 and adjacent the first pixel electrode 201 forms, can extend liquid crystal molecule in the occlusal area 2022 and also topple over and in pixel region 200, form a plurality of territories towards different directions respectively in zone up and down so that have second of negative polarity.
When next frame, the polarity of voltage counter-rotating that data line D1, D2 supply with, be that data line D1 is transfused to reverse voltage, data line D2 is transfused to positive polarity voltage, therefore, the first pixel electrode 201 is charged the pixel voltage of negative polarity, and the second pixel electrode 202 is charged the pixel voltage of positive polarity.Similarly, tilt and a plurality of territories of formation in pixel region 200 towards different directions respectively at the first extension occlusal area 2012 of the first pixel electrode 201 and the second liquid crystal molecule that extends in the occlusal area 2022 of the second pixel electrode 202.
During the varying in size of the pixel voltage that is charged when the first pixel electrode 201 and the second pixel electrode 202, the quantity in the territory that then forms in pixel region will double.
Therefore, the liquid crystal molecule in each pixel region 200 tilts and the formation multiple domain towards a plurality of directions respectively.When pixel region 200 has larger area, the liquid crystal molecule in each zone in the first pixel electrode 201 and the second pixel electrode 202 can extend by increasing respectively first in the first pixel electrode 201 the second quantity of extending occlusal area 2022 of occlusal area 2012 and the second pixel electrode 202 and further segment each pixel electrode, so that can both be well controlled.So, adopt the display panels of this dot structure to have good wide viewing angle characteristic.And, because extending occlusal area 2012, first in the first pixel electrode 201 have opposite polarity with its besieged second adjacent pixel electrode 202, in the second pixel electrode 202 second extends occlusal area 2022 and has opposite polarity with its besieged first adjacent pixel electrode 201, therefore, adopt the display panels of this dot structure to have the fast liquid crystal molecule response time.Further, adopt the display panels of this dot structure not need to arrange bulge-structure, therefore, when display panels was not worked namely not making alive, liquid crystal molecule can be good at the state of being kept upright, so, have high contrast.
In addition, the display panels of the embodiment of the invention is by red (R) in pixel, green (G), arrange respectively in blue (B) three sub-pixels and have jagged the first pixel electrode 201 and the second pixel electrode 202, and the first pixel electrode 201 and the engaged structure of the second pixel electrode 202, there be not overlapping the arranging between the adjacent subpixels in this Pixel Design structure, therefore, arranging of the pixel region of whole display panels is very regular, the overlapped capacitive coupling problem that causes because of pixel and data line can not occur, and can not affect red (R) in the colored filter substrate in the existing display panels, green (G), arranging of blue (B) look resistance layer.
