Description
Technical field
The present invention relates to a kind of drive unit that is applicable to LCD, particularly relate to a kind of driving method with high aperture (Aperture Ratio) and pel array of the pel array Driving technique that stable grey menu (Grey-scalePicture) can be provided.
Background technology
Generally speaking, LCD is distinguished according to type of drive, can be divided into passive type and active driving LCD.The LCD that adopts on the common mobile phone is passive type and drives LCD, the LCD of this type of kenel is because capacitive coupling (Capacitor Coupling) phenomenon is comparatively serious, and cause image quality low, such as ghost, contrast (Contrast) difference and reaction rate wait the generation of phenomenon slowly, add that it adopts multitask mode to drive usually, come complicated manyly than active drive type LCD by contrast, therefore, the LCD of this type is if will reach high-res, high image quality, it is very difficult that the target of full-colorization just seems, but, therefore often be applied to some comparatively in the monitor market of low order because its manufacturing cost is comparatively cheap.
The film transistor type LCD that is adopted on general mobile computer or the monitor is active drive formula LCD, the LCD of this type has been improved the shortcoming of the driving LCD of above-mentioned passive type, make the image quality and the resolution of LCD can do further lifting, its main key is the switchgear that it adopts thin film transistor (TFT) to rotate as the control liquid crystal molecule.
Seeing also shown in Figure 1ly, is the synoptic diagram of film crystal tube drive circuit.It comprises: data (be data, below all be called data) line 103, gate line 105, thin film transistor (TFT) 107, liquid crystal capacitance 109 and storage capacitors 111.At first in LCD, current potential is how to be applied on the liquid crystal molecule of each pixel (Pixel) at this, does a simple declaration.In active driving LCD, each pixel has a thin film transistor (TFT) 107, its gate is connected to the gate line of horizontal direction, can be described as gate line 105 again, source electrode be connected to vertically to data line, also can be described as data line 103, drain then is to be connected to pixel electrode (Pixel Electrode), be stressed that especially at this, source electrode and drain can be connected to data line and these two current potentials of pixel electrode separately, in operating process, be not to be set in to decide potential operations, but operating in the potential range that liquid crystal molecule allows always.
The function mode of this LCD, at first, gate line 105 of interior at one time one-shot, in order to all thin film transistor (TFT)s on this gate line 105, comprise that thin film transistor (TFT) 107 opens, send into corresponding data signal via data line 103, in order to pixel electrode is charged to suitable current potential.Then close thin film transistor (TFT) 107, up to the next time of write signal again again, electric charge is kept on the liquid crystal capacitance 109 therebetween; Restart next bar gate line this moment, sends into its corresponding data signal.So in regular turn the data of whole image is write finish after, more again from article one gate line write signal.Make the mutual influence of each pixel lower greatly because of so simple type of drive, and make the quality of LCD image quality and the electrical specification of thin film transistor (TFT) produce very big relevance, such as the pass electric current in the thin film transistor (TFT), drive current, stray capacitance (ParasiticCapacitance) and switching rate etc.
In addition, storage capacitors 111 is in order to assisting the storage of electric charge, thus its.Yet storage capacitors also has an important function in addition, promptly reduce the current potential coupling effect, be meant the current potential that is applied on the liquid crystal molecule at this represented current potential, be pixel electrode shared between pixel and the pixel and the potential difference (PD) between the pixel electrode, when thin film transistor (TFT) cuts out, pixel electrode is not connected to any potential source, but be in the state of unsteady (Floating), this moment pixel electrode around if any potential change arranged, this potential change can pass through stray capacitance, and be coupled to pixel electrode, cause the change of current potential, thereby influence is applied to the current potential on the liquid crystal molecule.Though increase storage capacitors the current potential coupling effect is reduced, but in general, because in two pixel electrodes of storage capacitors, having a pixel electrode at least is to make with lighttight metal, therefore increase the area that storage capacitors promptly increases storage capacitors, the peristome branch that this means light-permeable in the pixel reduces, and makes the luminescence efficiency of LCD integral body reduce.Therefore if want to reach the purpose of high aperture, normally form with complete self-aligned (Full Self Alignment), reduce the size of stray capacitance and storage capacitors by source/drain area.
Seeing also shown in Figure 2ly, is the synoptic diagram of the drive unit of existing known 3N*1 type of drive thin film transistor (TFT) array.Wherein comprise respectively from left to right, in order to show green pixel G222, in order to show blue pixels B225 with in order to showing red pixel R227, and the coupling capacitance 201～219 in each pixel.The characteristic of 3N*1 type of drive is distributed as for the polarities of potentials at the online pixel electrode of same horizontal gate +++--+++--+++---..., that is to say that being is a unit with three pixels, every a unit, the polarities of potentials of pixel electrode just changes once.Though can reduce the generation probability of transverse electric field, the uneven problem of picture brightness can take place, its cause description is as follows:
1, with pixel G222, because of adjacent two data line polarity identical, therefore there is not transverse electric field between two data lines, aperture opening ratio is very high, but its coupling capacitance (Coupling Capacitance) 205,207 has the effect that is equal to addition, makes reciprocal effect (Cross Talk) is become big.The situation of pixel R227 can also this be analogized.
2, with pixel B 225, because adjacent two data line polarity are different, therefore for the pixel B between these two data lines, its coupling capacitance 209,211 has the effect of subtracting each other, and makes reciprocal effect diminish.
Thus, can cause on the same picture brightness that the pixel B 225 in three pixels presented and pixel G, R222,227 brightness disproportionations that presented, thereby cause the shown image of panel can present inharmonious sense.Though the type of drive with 3N*1 can improve aperture opening ratio, but can produce the inharmonic shortcoming of picture.
This shows that the driving method of above-mentioned existing pel array still has defective, and demands urgently further being improved.For the defective of the driving method that solves existing pel array, relevant manufacturer there's no one who doesn't or isn't seeks solution painstakingly, but does not see always that for a long time suitable design finished by development, and this obviously is the problem that the anxious desire of relevant dealer solves.

Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, its concrete grammar of driving method, step, feature and the effect thereof of the pel array that foundation the present invention is proposed, describe in detail as after.
The following stated is based on the film transistor type LCD, but has the knack of this skill person when knowing that this kind type of drive goes in any similar array display drive apparatus.
This film transistor type LCD, constituted by thin-film transistor array base-plate, colorful filter array substrate and liquid crystal layer, wherein thin-film transistor array base-plate is by a plurality of thin film transistor (TFT)s with arrayed, and a pixel of corresponding configuration with each thin film transistor (TFT) is formed.Then comprised two pixel electrodes in each pixel, wherein a slice pixel electrode is electrically coupled to a common electric potential, and another sheet pixel electrode then is coupled to by thin film transistor (TFT) and is controlled the data line whether therewith pixel electrode electrically connects mutually.
Above-mentioned thin film transistor (TFT) is to comprise gate, drain and source electrode, is used as the switch module of liquid crystal display.Wherein, each pixel is controlled by one to four thin film transistor (TFT), because renewal frequency is higher, fuzzy image when making image energy have preferable contrast and can reduce picture and move, so be otherwise known as is active LCD, for imaging in the LCD Panel best but also be that price is the most expensive.Desirable film transistor type LCD is required to have high aperture and stable grey menu.So-called aperture opening ratio is meant the printing opacity ratio, just can allow the light source can be fully and more effectively cast out and reduce the ratio of light sources consume on the tft liquid crystal panel.The LCD that aperture opening ratio is high more has higher brightness and lower power consumption.In addition, so-called grey menu is meant by black to white gradually layer, just a pictures is by complete black slowly thin out, change to till the white always, so the sensation just as gradually the layer, and LCD can be complete present this gradually variation of layer, just need to consider the characteristic of thin film transistor (TFT) to design current potential dexterously.
Seeing also shown in Figure 3ly, is the driving circuit synoptic diagram that is adopted when implementing the driving method of pel array according to a preferred embodiment of the present invention.In the present embodiment, pel array 30 has comprised many data lines 306～324, many gate lines 327～333, a plurality of pixel 340～366, and a plurality of respectively according to the current potential of each gate line 327～333 and provide path 370～396 to pixel 340～366 with the current potential on the data line 306～324.For example, in the film transistor type LCD, in these paths 370～396 each is made up of thin film transistor (TFT) respectively, and be the control line of its gate, and electrically connect mutually with pixel electrode and its source/drain end of each pixel 340～366 with data line 306～324 with gate line 327～333.
In addition, be in the present embodiment with as the preceding situation that distributes in the current potential mode of the pixel electrode described in Fig. 2 be the explanation that example is done circuit layout.For current potential that driving method provided by the present invention can be provided at data line 306～324 is under the situation of alternate positive and negative, can make the Potential distribution mode of pixel electrode of each pixel same as shown in Figure 2, by this when reducing reciprocal effect, also can provide brightness even, stable grey menu, and can possess advantages such as the transverse electric field ratio of reduction and high aperture in the lump, the present invention is divided into groups each pixel 340～366 earlier, and with the current potential of homophase phase place in fact (as just be similarly or be similarly negative) pixel electrode current potential as each pixel in each pixel groups, and with the current potential that is essentially inverted phases (as one for just another for negative) be respectively the pixel electrode current potential of each pixel in adjacent two pixel groups.Thus, the current potential that just can form pixel electrode as shown in Figure 2 is +++--+++--+++---... distribution mode.And in design path 370～396, then must make this pel array 30 to drive the two adjacent pixels that are positioned at adjacent two pixel groups intersections with same gate line (as gate line 330), and with same gate line drive a certain pixel that is arranged in same pixel groups and therewith adjacent the listing of pixel have the pixel of the pixel electrode current potential of the phase place of being different in essence.
For instance, if with pixel 340～344 is first pixel groups, pixel 346～350 is second pixel groups, pixel 354～358 is the 3rd pixel groups and pixel 360～364 is the 4th pixel groups, then must drive the pixel electrode of each pixel in first pixel groups and the 4th pixel groups with the current potential of same-phase (as positive potential) in fact, and to drive the pixel electrode of each pixel in second pixel groups and the 3rd pixel groups in fact with the current potential of the current potential anti-phase (as negative potential) that drives first pixel groups.
At the current potential with alternate positive and negative is under the prerequisite of the current potential that provided of data line 306～324, if the current potential by data line 306 beginning is respectively+-+-+-+-, then under the control of gate line 330, just the current potential that data line 306～324 is provided must be inducted into respectively in the pixel that need possess the comparative electrode current potential.At this, in order to simplify the numerous and diverse of circuit design, present embodiment is to be the object of design circuit path with the pixels of adjacent two row (that is, by gate line 327 with 330 folded one-row pixels and by gate line 330 and 333 another folded capable pixels).Therefore, the positive potential that is provided by data line 306 will enter into the pixel electrode of pixel 340 by the path of being controlled by gate line 330 370, makes that by this pixel electrode of pixel 340 is a positive potential.Next, because data line 309 negative potential that provides, therefore it can not be imported expection and should be on the pixel electrode of pixel 342 of positive potential.Replace, the negative potential that is provided by data line 309 will be fed to pixel 342 and be positioned at same row, and the current potential of the pixel electrode of its expection should be in the pixel 356 of negative potential.
Next, can be by the positive potential that data line 312 provided because enter in the pixel electrode of last pixel 344 in first pixel groups with the identical relation of pixel 340 with above-mentioned data line 306.For first pixel 346 in second pixel groups adjacent with first pixel groups, owing to originally just expect that the current potential of pixel electrode of this pixel 346 should be negative potential, therefore just can directly be provided for pixel 346 by data line 315 entrained negative potentials via path 376.After this, remaining pixel 348～366 also will be followed similar mode and be carried out driving.
In other words, after pixel groups is set, to with the current potential that is essentially same phase the pixel electrode current potential of each pixel in some pixel groups according to this embodiment of the invention, and with the current potential that the is essentially inverted phases pixel electrode current potential as each pixel in adjacent two pixel groups.In addition, more drive the two adjacent pixels that are positioned at adjacent two pixel groups intersections in this embodiment with same gate line, and drive a certain pixel that is arranged in a pixel groups with same gate line, and adjacent the listing of pixel has the pixel of the pixel electrode current potential of the phase place of being different in essence therewith.
If will consider regular and the design simplification, be preferable with each self-contained identical pixel of each pixel groups in this suggestion.Further, if the number of pixels that each pixel groups comprised is 3 or 3 integral multiple, then because three kinds of colors of R, G, B of forming a point on the picture can be divided into same pixel groups, so can further reach the balance on the color.In addition, in fact, in each pixel groups the number of the pixel that can comprise and nonessential unalterable, have the knack of this operator and work as requiredly and adjusted according to self.
Seeing also shown in Figure 4ly, is the schematic flow sheet according to the driving method of the pel array of another preferred embodiment of the present invention.In the present embodiment, at first must be with the pixel in the pel array according to its place trip grouping, wherein a kind of mode of grouping is that as shown in Figure 3 embodiment is general.Yet the range of application of this and unrestricted present embodiment is in fact so long as be arranged in the pixel in the delegation and all can divide at same group.Moreover, except with the group pixels, also must also do corresponding grouping (step S400) by used data line when driving each pixel.Certainly, grouping herein can only be grouping in logic, and nonessential be the in fact grouping of circuit.
After through grouping, the relation (step S402) between the prime data line before in formal the driving, must judging a present data line of present control and be positioned at this present data line.If data line and prime data line belong to same data line group at present, just must drive the pixel (step S404) that the pixel that is driven with the prime data line adheres to different rows separately with the online data that is provided of present data.Otherwise,, then drive the pixel (step S406) that is connected in after the pixel that is driven by the prime data line with the data that present data line was provided if at present data line and prime data line do not belong to same data line group.
Seeing also shown in Figure 5ly, is the circuit when using according to the driving method of another preferred embodiment of the present invention.Circuit with reality, if with pixel 540 and 542 is first pixel groups, and be second pixel groups with pixel 544～548, then relative data line 506 and 509 also will be set to the first data line group, and data line 512～518 then can be configured to the second data line group.According to by the step that embodiment provided shown in Figure 4, at first data line 506 can be used to drive pixel 540.Next, when will judging the driving pixel of data line 509, because data line 509 (being aforesaid present data line this moment) belongs to same data line group with data line 506 (being aforesaid prime data line this moment), therefore data line 509 must be in order to the pixel (in circuit shown in Figure 5, promptly being used to drive pixel 552) that drives non-genus first pixel groups.Relative, in the driving pixel of judging data line 512, because data line 512 (being aforesaid present data line this moment) is not to belong to same data line group with data line 509 (being aforesaid prime data line this moment), therefore data line 512 will be used to drive pixel 554, just is positioned at the pixel after the pixel that is driven by the prime data line.
It must be noted that though aforementioned several embodiment are to be example with fixing passage (370～396 and 570～578), in fact these passages can be configured to change and its pixel of electric property coupling mutually according to corresponding controlling signal.
In order to make LCD can have brighter brightness and lower power consumption, what can improve is to reduce the thin film transistor (TFT) size and aperture opening ratio can be improved.Higher carrier mobility can make undersized thin-film transistor component can keep enough drive currents, and high aperture then can reduce parasitic size with overlap capacitance and storage capacitors and reach on processing procedure by the complete formed source/drain area of self-aligned.Because the hesitation that electric capacity caused is the big factors that causes the LCD brightness deficiency.
In sum,, can make the coupling capacitance generation in the pixel be equal to the effect of subtracting each other, reduce reciprocal effect so that the polarities of potentials of the data line about pixel is different by driving method provided by the present invention.Moreover, when the reciprocal effect degree of pixel G, pixel B and pixel R is all identical, more can therefore provide brightness even and stable grey menu.In addition, if on same horizontal direction with +++--+++--+++---mode arrange the current potential of pixel electrode, then more can further reduce the ratio of transverse electric field, make it have the advantage of high aperture.
The above, it only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, though the present invention discloses as above with preferred embodiment, yet be not in order to limit the present invention, any those skilled in the art, in not breaking away from the technical solution of the present invention scope, when the method that can utilize above-mentioned announcement and technology contents are made a little change or be modified to the equivalent embodiment of equivalent variations, in every case be the content that does not break away from technical solution of the present invention, according to technical spirit of the present invention to any simple modification that above embodiment did, equivalent variations and modification all still belong in the scope of technical solution of the present invention.
