The present invention is one and divides an application that the applying date of original application is: on Dec 5th, 2007; Original applying number is: 200710196471.4; Former invention and created name is: display and display system.

Technical field

(Liquid Crystal Display LCD), and is particularly related to a kind of driving mechanism that is applied to LCD to the present invention relates to a kind of LCD.

Background technology

LCD is used for the monochrome display like computing machine and electronic watch the earliest; Now has become the main flow that shows in the science and technology; And in computer monitor or television indicator industry, LCD all replaced cathode-ray tube (CRT) (cathode ray tube, CRT).In addition, thus the shortcoming of many LCDs also has been overcome the quality of having improved LCD.For instance, compare with the passive type array display, active formula array display can reduce ghost phenomena (ghosting), and can promote resolution, color range, visual angle, contrast and reaction time, and has extensively replaced the passive type array display.

Yet the major defect of traditional twisted nematic (twisted nematic) LCD is narrow visual angle and low contrast, even the visual angle of active formula array display is still much smaller than the visual angle of cathode-ray tube (CRT).Particularly, when the spectators that are positioned at the LCD dead ahead watched high-quality image, other spectators that are positioned at the LCD both sides just can't watch high-quality image.Therefore, multi-domain vertical alignment liquid crystal displays just arises at the historic moment and is used to promote the visual angle and the contrast of LCD.Fig. 1 (a)～Fig. 1 (c) illustrates the basic function of the pixel of homeotropic liquid crystal display 100, and for asking clarity, the LCD of Fig. 1 only illustrates single territory (domain).In addition, Fig. 1 (a)～1 (c) and Fig. 2 illustrate the manner of execution of the GTG operation of LCD.

LCD 100 comprises first polaroid 105, first substrate 110, first electrode 120, first both alignment layers 125, a plurality of liquid crystal 130, second both alignment layers 140, second electrode 145, second substrate 150 and second polaroid 155.Generally speaking, first substrate 110 and second substrate 150 are made up of clear glass, and first electrode 120 and second electrode 145 are made up of the electrically conducting transparent material such as indium tin oxide (Indium Tin Oxide).(polyimide PI) constitutes, and under static state, can make liquid crystal 130 homeotropic alignments by pi usually for first both alignment layers 125 and second both alignment layers 140.When operation, the light source (not shown) can send light beam from first polaroid, 105 belows, and wherein first polaroid 105 is attached on first substrate 110.First polaroid 105 usually with first direction with light beam polarizationization, and first polaroid 105 is vertical each other with the polarization direction of second polaroid 155, and second polaroid 155 is attached on second substrate 150.So the light beam that light source sends can't pass through first polaroid 105 and second polaroid 155 simultaneously, only if the polarization direction of light beam is rotated between the polarization direction of 90 ° and arrive first polaroid 105 and second polaroid 155.For asking clear expression; A spot of liquid crystal only is shown among the figure; And in fact; Liquid crystal is the molecular structure just like column; Wherein the liquid crystal diameter be about and liquid crystal length be about

so; In the pixel region of long 300 μ m, wide 100 μ m, high 3 μ m, 10,000,000 liquid crystal molecules of surpassing are arranged approximately.

In Fig. 1 (a), liquid crystal 130 homeotropic alignments, and the polarization direction that the liquid crystal 130 of homeotropic alignment can't rotary light source are so the light beam that light source sends can't pass through LCD 100.So for all colors and liquid crystal layer spacing (cell gap), LCD 100 can provide optics dark state (optical black state) and very high contrast completely.Therefore compare with the Twisted Nematic LCD of traditional low contrast, multi-domain vertical alignment liquid crystal displays provides sizable improvement on contrast.Yet shown in Fig. 1 (b), when applying electric field between first electrode 120 and second electrode 145 time, liquid crystal 130 can redirect to lateral attitude.Liquid crystal under lateral attitude can be with the polarization direction half-twist of the polarized light through first polaroid 105, thereby makes light beam can pass through second polaroid 155.The degree that liquid crystal tilts is proportional to electric field intensity, and is used for controlling the light quantity (being the brightness of pixel) through LCD.Generally speaking, (thin-film-transistor, TFT) correspondence is disposed in the single pixel a single thin film transistor (TFT).But in color monitor, single one thin film transistor (TFT) correspondence is disposed at as in the red bluish-green solid color component member (color component).

Yet as far as watch the spectators of LCD 100 in different visual angles, its light beam of watching is not uniform.Shown in Fig. 1 (c), because liquid crystal 130 broadsides (with the light polarization direction rotation) are over against the spectators that take back 172, so spectators 172 can see complete bright pixel.In addition, because liquid crystal 130 broadside portion are over against the spectators 174 of centre, so spectators 174 can see the pixel of GTG.Relatively, because liquid crystal 130 broadsides are not almost over against the spectators that take over 176, so spectators 176 can see complete dark pixel.

The development of multi-domain vertical alignment liquid crystal displays is with the too small problem in visual angle that solves single domain (single-domain) homeotropic liquid crystal display.Fig. 2 illustrates the single pixel in the multi-domain vertical alignment liquid crystal displays (MVA LCD) 200.Multi-domain vertical alignment liquid crystal displays 200 comprises first polaroid 205, first substrate 210, first electrode 220, first both alignment layers 225, a plurality of liquid crystal 235,237, a plurality of thrust (protrusion) 260, second both alignment layers 240, second electrode 245, second substrate 250 and second polaroid 255; Wherein liquid crystal 235 constitutes first field of pixels, and liquid crystal 237 constitutes second territory of pixel.When applying electric field between first electrode 220 and second electrode 245 time, thrust 260 can make liquid crystal 235 topple over toward different directions with liquid crystal 237.Thus, territory, the left side (liquid crystal 235) meeting that the spectators 272 that take back are seen is like dim spot, and territory, the right (liquid crystal 237) can be like bright spot.In addition, the spectators 274 of centre can see the territory of two GTGs.Relatively, territory, the left side (liquid crystal 235) meeting that the spectators 276 that take over are seen is like bright spot, and territory, the right (liquid crystal 237) can be like dim spot.In any case, because the zone of individual pixel is all very small, so as far as these three spectators, its pixel status of experiencing is the effect of GTG.As previously mentioned, the degree that liquid crystal tilts depends on the electric field intensity between first electrode 220 and second electrode 245, and the GTG degree that spectators experienced is just directly relevant with the degree of liquid crystal inclination.Multi-domain vertical alignment liquid crystal displays also extends to and uses four territories, and also being about to single pixel segmentation is four territories, and makes and in vertical direction and horizontal direction symmetrical effect of wide angle can be provided all.Also proposed otherwise to form multi-domain vertical alignment liquid crystal displays at present; For example; Mr. Wang Xieyou has described a kind of multi-domain vertical alignment liquid crystal displays that need not thrust with regard to knowing in the U. S. application patent; Wherein the application case of this patent number is 11/227,595, open case number is " multi-domain vertical alignment liquid crystal displays (LARGE-PIXEL MULTI-DOMAIN VERTICAL ALIGNMENT LIQUID CRYSTAL USING FRINGE FIELDS) with big pixel and applying edge electric field " for 2007/0058122A1, title.Thus, multi-domain vertical alignment liquid crystal displays can provide the wide viewing angle of high-contrast and symmetry.

Fig. 3 is the fragmentary, perspective view of LCD 300.LCD 300 comprises first polaroid 302, and first polaroid 302 is attached on the substrate 305.Fig. 3 illustrates three pixel P (0,0), P (0,1), P (0,2), and each pixel comprises three color particles (color dot) CD_1, CD_2, CD_3.Colored filter (color filter) (not shown) is used for producing chromatic image.For instance, for color particle CD_1, CD_2, CD_3, colored filter has corresponding red window (red window), green windows and blue window respectively.Fig. 3 also illustrates the electrode of these color particles, but for asking consistent, these electrodes also are expressed as CD_1, CD_2, CD_3.The electrode of these color particles is formed on the upper surface of substrate 305, and the both alignment layers (not shown) can cover these electrodes.As shown in Figure 3, each color particle can have the corresponding switch element.Particularly; In arbitrary pixel; On-off element SE1, SE2, SE3 be corresponding color particle CD_1, CD_2, CD_3 respectively, and on-off element can be the n slot field-effect transistor (n-channel Field Effect Transistor) that adopts thin film technique (thin film technology) to process.

These on-off elements provide power supply via the control line of two kinds of different types, and wherein the control line of these two kinds of patterns is gate line (G0, G1, G2) and source electrode line (S0_1, S0_2, S0_3).With pixel P (0; 0) specifies for example; Then the grid of its on-off element SE1, SE2, SE3 is coupled to gate lines G 0; And the source electrode of its on-off element SE1, SE2, SE3 is coupled to source electrode line S0_1, S0_2, S0_3 respectively, and the drain electrode of its on-off element SE1, SE2, SE3 is coupled to the electrode of the color particle CD_1 of pixel P (0,0), CD_2, CD_3 respectively.(X, Y), then the grid of its on-off element SE1, SE2, SE3 is coupled to gate lines G Y, and the source electrode of its on-off element SE1, SE2, SE3 is coupled to source electrode line SX_1, SX_2, SX_3 respectively with pixel P.In typical liquid crystal, gate line is controlled by the integrated circuit (integrated circuit) that is called " line driver (row driver) ", and source electrode line is controlled by the integrated circuit that is called " row driver (column driver) ".The extra integrated circuit that is used for controlling polarity will detail in the back.Fig. 4 (a) illustrates the detailed method of application of the control line in the display 400, and control line is source electrode line and gate line (this can detail in the back).Electrically connect member and typically adopt transparent conductor, and the both alignment layers (not shown) is covered on the electrode such as indium tin oxide (ITO).Although Fig. 3 is also not shown, some display also can comprise storage capacitors, and wherein storage capacitors is the electrode that is coupled to the color particle, in order to keep suitable amount of charge.

Fig. 4 (a) illustrates the sub-fraction (six pixels) of display 400, and particularly, Fig. 4 (a) illustrates pixel P (0,0), P (0,1), P (0,2), P (1,0), P (1,1), P (1,2).Each pixel comprises three color particle CD_1, CD_2, CD_3 and three transistors.The display 400 of Fig. 4 (a) also comprises source electrode line S0_1, S0_2, S0_3, S1_1, S1_2, S1_3 and gate lines G 0, G1, G2, G3.Generally speaking, source electrode line SX_Z is corresponding with gate lines G Y act on pixel P (X, on color particle CD_Z Y), and pixel P (X Y) promptly is X pixel on Y is capable.Transistorized source electrode, grid and drain electrode are the electrodes that is coupled to source electrode line, gate line and color particle respectively.For asking clear expression, this with these transistors be expressed as transistor T (X, Y, Z), wherein transistor T (source electrode Z) is coupled to source electrode line SX_Z for X, Y, and transistor T (grid Z) is coupled to gate lines G Y for X, Y.In display 400, (drain electrode Z) is coupled to pixel P (X, color particle CD_Z Y) to transistor T for X, Y.For example, three color particle CD_1, CD_2, the CD_3 of pixel P (0,1) are coupled to transistor T (0,1,1), T (0,1,2), T (0,1,3) respectively.Transistor T (0,1,1), T (0,1,2), T (0,1; 3) grid is coupled to gate lines G 1, and transistor T (0,1,1), T (0,1,2), T (0; 1,3) source electrode is coupled to source electrode line S0_1, S0_2, S0_3 respectively, and transistor T (0,1,1), T (0; 1,2), the drain electrode of T (0,1,3) is coupled to color particle CD_1, CD_2, the CD_3 of pixel P (0,1) respectively.For asking clear expression, shadow representation is used in the zone of each pixel, and this shade only is used for key drawing 4 (a), does not have the meaning on any function.

Each bar gate line extends to the right from the left side of display 400, and in the control display 400 with all pixels in the delegation, and for the pixel on arbitrary row, display 400 can have corresponding gate line.In addition; Each bar source electrode line extends to the base from the top margin of display 400; And display 400 has many source electrode lines, and wherein the quantity of source electrode line is three times (that is color component members of a corresponding pixel of source electrode line) of the pixel quantity on arbitrary row.When display is operated, only there is a gate line can start (active) at every turn.For the thin film transistor (TFT) of traditional amorphous silicon (amorphous silicon) n channel metal oxide semiconductor transistor (NMOS TFT) technology; When the grid potential of n channel metal oxide semiconductor transistor was drawn high, this transistor just can start.All crystals pipe starting on the row (active row) will present the state of conducting by the forward grid impulse (positive gate impulse) that starts gate line, then can present the state that opens circuit because putting on the negative voltage on non-startup (non-active) gate line as for the transistor on other row.In other were used, the transistor on other row also can present the state that opens circuit because of the non-startup gate line of ground connection (grounding).For the thin film transistor (TFT) of monocrystalline silicon (single crystalline silicon) P-channel metal-oxide-semiconductor transistor (PMOS TFT) technology; When the transistorized grid potential of P-channel metal-oxide-semiconductor was dragged down, this transistor just can start.In addition, all source electrode lines all can start simultaneously, and every source electrode line can provide image data to the transistor that starts on the row (active row), wherein start row by starting gate line control.So according to the mode of operation of gate line and source electrode line, gate line is called bus (bus line) again, and source electrode line also can be described as data line (data line).Voltage can charge to a specific GTG (gray scale level) with liquid crystal capacitance, and produces color by optical filter.When transistor under non-startup, the electrode of color particle just is in the state of electrical isolation (isolated), thereby the intensity that can keep electric field is with the control liquid crystal.Yet parasitic leakage (parasitic leakage) is unavoidable, so final electric charge will all run off.For the few small-size screen of row (row) number, because voltage of each row through renewals of being everlasting, is not problem so leak electricity.But for the more large-sized monitor of number of lines, each row must be waited for the long time between the moment of twice renewal.Thus, some display can dispose one or more storage capacitors for the color particle.These storage capacitors are charged with the electric capacity of color particle, and under non-startup row state, provide so-called and keep (maintenance) electric charge.In addition, the material of bus and data line can comprise like aluminium (Al) or chromium non-printing opacity conductors (opaque conductor) such as (Cr).

Electrode in these LCDs can have positive polarity (positive polarity) or negative polarity (negative polarity).In the figure frame of taking over continuously (successive frames), electrode can replace switch polarity and reduce to avoid image quality.If at each figure frame, liquid crystal all rotates same direction, just same polarity will cause the liquid crystal deterioration for a long time, and image quality will reduce.The mode of two kinds of control polarity is direct current V-com (DC V-com) and exchanges V-com (AC V-com) that wherein V-com is transistorized common reference voltage.In direct current V-com, the signal of source electrode driver also will directly be controlled the polarity of color particle except the brightness of control color particle, and the fixed value of common reference voltage V-com for not changing.In exchanging V-com, common reference voltage V-com is periodically-varied via the V-com reference circuit, and the data of source electrode line only are used to control the brightness of color particle, and extra circuit (not shown) can be used for controlling the polarity of color particle.In exchanging V-com, when liquid crystal (being the color particle) when still being applied in identical effective voltage, the voltage range that acts on the source electrode line can be less than the required voltage range that acts on the source electrode line of direct current V-com drive system.

If all on-off elements all have identical polarity chron, switch polarity still can cause the image problem like film flicker (flicker), then can carry out space average (spatial averaging) and reduce film flicker.Particularly, these on-off elements are arranged in through driving mechanism (driving scheme) and have positive-negative polarity.In addition, (cross talk) phenomenon of crosstalking in order to reduce, the on-off element of positive polarity and negative polarity need be arranged in uniform kenel, and this also makes electrical more even distribution.

Can use many on-off element driving mechanisms, and three kinds of main on-off element driving mechanisms are on-off element point counter-rotating (point inversion) driving mechanism, the capable counter-rotating of on-off element (row inversion) driving mechanism and on-off element row counter-rotating (column inversion) driving mechanism respectively.Fig. 4 (b)～4 (d) illustrates different on-off element driving mechanisms, in the electrode of color particle, representes positive polarity with "+", and with "-" expression negative polarity.In on-off element point inversion driving mechanism, the on-off element of alter polarity constitutes the draughtboard pattern.Fig. 4 (b) is that illustration goes out on-off element point inversion driving mechanism with display 410, and wherein display 410 has identical basic layout (layout) with display 400.Particularly, when ordinal number X added that ordinal number Y adds Z (being X+Y+Z) for odd number, then (X, color particle CD_Z Y) had positive polarity to pixel P.On the contrary, when ordinal number X added that ordinal number Y adds Z (being X+Y+Z) for even number, then (X, color particle CD_Z Y) had negative polarity to pixel P.Yet when changing to next figure frame, all color particles all can switch polarity and the polarity of changeabout.

In the capable inversion driving mechanism of on-off element, have identical polarity with the on-off element in the delegation, but the polarity of on-off element can be opposite with the polarity of on-off element on the adjacent lines on arbitrary row.Fig. 4 (c) is that illustration goes out the capable inversion driving mechanism of on-off element with display 420, and wherein display 420 has identical basic layout with display 400.In Fig. 4 (c), when ordinal number Y was even number, then (X, color particle CD_Z Y) had positive polarity to pixel P.On the contrary, when ordinal number Y was odd number, then (X, color particle CD_Z Y) had negative polarity to pixel P.Yet when changing to next figure frame, all color particles all can switch polarity and the polarity of changeabout.

In on-off element row inversion driving mechanism, the same on-off element that lists has identical polarity, but arbitrary polarity that lists on-off element can be opposite with the polarity of on-off element on the adjacent columns.Fig. 4 (d) is that illustration goes out the capable inversion driving mechanism of on-off element with display 430, and wherein display 430 has identical basic layout with display 400.In Fig. 4 (d), when ordinal number X added that ordinal number Z is odd number, then (X, color particle CD_Z Y) had positive polarity to pixel P.On the contrary, when ordinal number X added that ordinal number Z is even number, then (X, color particle CD_Z Y) had negative polarity to pixel P.Yet when changing to next figure frame, all color particles all can switch polarity and the polarity of changeabout.

Although display 410,420,430 has identical basic layout, but corresponding driving mechanism differs very big, and corresponding driving circuit is also very different.In the capable inversion driving mechanism of on-off element, vertical crosstalk phenomenon can significantly reduce.On the contrary, in on-off element row inversion driving mechanism, the crosstalk phenomenon of level can significantly reduce.In addition, among both, the phenomenon of image flicker all can reduce through space average in the capable inversion driving mechanism of on-off element and on-off element row inversion driving mechanism.By the crosstalk phenomenon that reduces level and vertical direction simultaneously, on-off element point inversion driving mechanism can provide best image quality.In addition, for capable inversion driving mechanism of on-off element or on-off element row inversion driving mechanism, have better space average effect, can further significantly reduce the phenomenon of image flicker by on-off element point inversion driving mechanism.

Yet, to compare with the capable inversion driving mechanism of on-off element, the efficiency of energy utilization of on-off element point inversion driving mechanism is relatively poor, cost of manufacture is expensive, and more difficult on the implementation.Particularly, on-off element point inversion driving mechanism can't be applicable to and exchange among the V-com.Thus, the machine-processed direct current V-com drive system of just must arranging in pairs or groups of traditional on-off element point inversion driving, and the power supply of need arrange in pairs or groups high-tension source electrode driver and high voltage.Therefore the capable inversion driving mechanism of on-off element compared with on-off element point inversion driving mechanism applicable to exchanging among the V-com, and the capable inversion driving of on-off element is machine-processed available lower voltage-operated, and has lower electrical source consumption.In addition; The integrated circuit that can implement on-off element point inversion driving mechanism needs the manufacturing process of high voltage (12 volts); And the integrated circuit of implementing the capable inversion driving mechanism of on-off element only needs the manufacturing process of low-voltage (5 volts), and the required cost of its high voltage appearance manufacturing process is much larger than the cost of low-voltage manufacturing process.In addition, implement the die size of nude film (die) size of the machine-processed integrated circuit of on-off element point inversion driving greater than the integrated circuit of implementing the capable inversion driving mechanism of on-off element.Thus, no matter be on cost of manufacture or energy dissipation, adopt on-off element point inversion driving mechanism all than adopting the capable inversion driving mechanism of on-off element to come expensively.But, image quality can improve because adopting on-off element point inversion driving mechanism really.So, being necessary to propose a kind of method or system, it can avoid the expensive manufacturing cost and the high-energy consume of conventional switch element point inversion driving mechanism, and the on-off element point inversion driving image quality that mechanism is appeared still can be provided.

Embodiment

As previously mentioned, compare, adopt the conventional liquid crystal of on-off element point inversion driving mechanism generally better image quality can be provided with the LCD that adopts the capable inversion driving mechanism of on-off element.Yet, compare with the LCD that adopts the capable inversion driving mechanism of on-off element, adopt the manufacturing cost of the machine-processed LCD of on-off element point inversion driving comparatively expensive, and energy dissipation is higher.Use principle of the present invention,, adopt the display of the novel on-off element point inversion driving mechanism of the present invention to have lower cost of manufacture and lower operating power with the display in comparison that adopts the capable inversion driving mechanism of on-off element.

In the capable inversion driving mechanism of on-off element, the transistor on the identical gate line has identical polarity (asking for an interview Fig. 4 (c)).In one embodiment of this invention, the transistor may command on same gate line is positioned at the color particle that a plurality of row make progress.Fig. 5 illustrates according to the sub-fraction of the display 500 of one embodiment of the invention (six pixels), and particularly, Fig. 5 illustrates pixel P (0; 0), P (0,1), P (0,2), P (1; 0), P (1; 1), P (1,2), and each pixel comprises three color particle CD_1, CD_2, CD_3 and three transistors.Fig. 5 also comprises source electrode line S0_1, S0_2, S0_3, S1_1, S1_2, S1_3 and gate lines G 0, G1, G2, G3.Each bar gate line extends to the right from the left side of display 500, and controls in the display 500 with all pixels in the delegation.The color particle that corresponding certain delegation of single the gate line of the display 400-430 of Fig. 4 (a)-4 (d) makes progress; Different with it is; The color particle that single gate line of the display 500 of Fig. 5 controlled can be positioned at surpass more than one row to, literary composition details in the back and this names a person for a particular job.Each bar source electrode line extends to the base from the top margin of display 500, and display 500 has many source electrode lines, and wherein the quantity of source electrode line is three times (that is color component members of a corresponding pixel of source electrode line) of the pixel quantity on arbitrary row.When display is operated; Only there is a gate line to start at every turn; And will present the state of conducting by the forward grid impulse that starts gate line at all crystals pipe that starts on the row, then can present the state that opens circuit as for the transistor on other row because putting on the negative voltage on the non-startup gate line.In addition, all source electrode lines all can start simultaneously, and every source electrode line can provide image data to the transistor that starts on the row, wherein start row by starting gate line control.So according to the mode of operation of gate line and source electrode line, gate line is called bus again, and source electrode line also can be described as data line.Voltage can charge to a specific GTG with liquid crystal capacitance, and produces color by colored filter.When transistor under non-startup, the electrode of color particle just is in the state of electrical isolation, thereby the intensity that can keep electric field is with the control liquid crystal.Yet parasitic leakage is unavoidable, so final electric charge will all run off.For the few small-size screen of number of lines, because voltage of each row through renewals of being everlasting, is not problem so leak electricity.But for the more large-sized monitor of number of lines, each row must be waited for the long time between the moment of twice renewal.Thus, some display can dispose one or more storage capacitors for the color particle.These storage capacitors are charged with the electric capacity of color particle, and under non-startup row state, the so-called electric charge of keeping are provided.

In display 500, transistorized source electrode, grid and drain electrode are coupled to the electrode of source electrode line, gate line and color particle respectively.For asking clear expression, this with these transistors be expressed as transistor T (X, Y, Z), wherein transistor T (source electrode Z) is coupled to source electrode line SX_Z for X, Y, and transistor T (grid Z) is coupled to gate lines G Y for X, Y.Display 500 is just that with the main difference of display 400-430 connected mode is different, and in display 500, these transistor may command that are coupled to identical gate line are positioned at the color particle that different rows makes progress.For example, the row that the color particle (can be the first color particle) that transistor T (0,1,1) is controlled is positioned at gate lines G 1 top upwards, and the row that the color particle that transistor T (0,1,2) is controlled (can be the second color particle) is positioned at gate lines G 1 below is upwards.In display 500, when ordinal number X added that ordinal number Z is even number, then (X, Y, the color particle of Z) being controlled were positioned at transistor T (X, Y, Z) top to transistor T.When ordinal number X added that ordinal number Z is odd number, then (X, Y, the color particle of Z) being controlled were positioned at transistor T (X, Y, Z) below to transistor T.Thus; When gate lines G 1 starts; A color particle just can start the color particle that these row that are positioned at gate lines G 1 top make progress since the every interval of the first color particle, and the color particle that makes progress of these row that are positioned at gate lines G 1 below a color particle just can start since the every interval of the second color particle.As previously mentioned, when application switch element row inversion driving device, these color particles by transistor controls have identical polarity, and wherein these transistors are coupled to same gate line.As shown in Figure 5, just the polarity pattern of the display (shown in Fig. 4 (b)) that the polarity pattern that is constituted at the color particle among Fig. 5 can be machine-processed with adopting on-off element point inversion driving is identical.

Because the transistorized connected mode of display 500 changes, so the shape of the pixel of display 500 is different from the shape of the pixel of display 400-430.For asking clear expression, shadow representation is used in the zone of the pixel of each display 500, and this shade only is used for key drawing 5, does not have the meaning on any function.In display 500, pixel P (0,1) comprises three color particle CD_1, CD_2, CD_3, and these three color particles are coupled to transistor T (0,1,1), T (0,1,2), T (0,1,3) respectively.Yet color particle CD_1, the CD_3 of the color particle CD_2 of pixel P (0,1) and pixel P (0,1) is positioned at different row upwards.In detail, transistor T (0,1,1), T (0,1,2), T (0; 1,3) grid is coupled to gate lines G 1, and transistor T (0,1,1), T (0,1; 2), the source electrode of T (0,1,3) is coupled to source electrode line S0_1, S0_2, S0_3 respectively, and transistor T (0,1,1), T (0; 1,2), the drain electrode of T (0,1,3) is coupled to color particle CD_1, CD_2, the CD_3 of pixel P (0,1) respectively.Yet the color particle CD_1 of pixel P (0,1), CD_3 are positioned at delegation and make progress, and this journey is to being above gate lines G 1, and the row at the color particle CD_2 of pixel P (0,1) place is to being below gate lines G 1.In display 500, pixel P (1,1) comprises three color particle CD_1, CD_2, CD_3, and these three color particles are coupled to transistor T (1,1,1), T (1,1,2), T (1,1,3) respectively.Yet color particle CD_1, the CD_3 of the color particle CD_2 of pixel P (1,1) and pixel P (1,1) is positioned at different row upwards.In detail, transistor T (1,1,1), T (1,1,2), T (1; 1,3) grid is coupled to gate lines G 1, and transistor T (1,1,1), T (1,1; 2), the source electrode of T (1,1,3) is coupled to source electrode line S1_1, S1_2, S1_3 respectively, and transistor T (1,1,1), T (1; 1,2), the drain electrode of T (1,1,3) is coupled to color particle CD_1, CD_2, the CD_3 of pixel P (1,1) respectively.Yet the color particle CD_1 of pixel P (1,1), CD_3 are positioned at delegation to make progress, and this journey is to being below gate lines G 1, and the row at the color particle CD_2 of pixel P (1,1) place is to being above gate lines G 1.

In display 500, these transistors in each bar gate line replace control and are positioned at the color particle that first row makes progress and second row makes progress.By alternately utilizing these transistors, the present invention can adopt the mode of the capable counter-rotating of on-off element to reach the effect of on-off element point counter-rotating.Yet in certain embodiments of the present invention, being positioned at first row is not that symmetry (uneven) distributes with second row these color particles upwards upwards.For example, on the gate line in one embodiment of this invention, whenever just be coupled to second row color particle upwards at a distance from three transistors, other transistor then is coupled to first row color particle upwards.Because the first, the 3rd color component member and the second color component member skew in vertical direction of each pixel make display 500 be characterised in that the color arrangement of skew.This characteristic is applicable to staggered color scheme (delta type color layout), and compares with traditional candy strip color scheme (stripe pattern color layout), and staggered kenel color scheme has higher image quality.

Yet, to compare with staggered kenel color scheme, the candy strip color scheme has better literal display quality.To use the display of striped pattern color configuration, some embodiment of the present invention comprises that a kind of novel driving mechanism is to promote the color arrangement.Particularly, in pixel 500, why the characteristic that this skew color is arranged produces, and is to surpass a row to above color particle because the transistor on the gate line is coupled to.This novel driving mechanism postpones source signal, to arrange these color component members again.

Fig. 6 illustrates the display 600 according to this novel driving mechanism of employing of one embodiment of the invention.Fig. 6 is similar with Fig. 5, and its difference only is that some signal that puts on the source electrode line can be postponed, so similarly explanation just no longer repeats.Particularly, postponing source signal S0_2_D, S1_1_D, S1_3_D, to put on source electrode line S0_2, S1_1, S1_3 respectively last.In one embodiment of this invention, postponing source signal is to produce via the delay circuitry (delay circuitry) in the time controller (time controller).In another embodiment of the present invention; The time control lag unit of one independent (separate) (time control delay unit) collocation puts on source electrode line S0_2, S1_1, last source signal S0_2, S1_1, the S1_3 (like the use-pattern of Fig. 5) of S1_3, and this timing period equals single row during upgrading.The traditional element control lag unit or change (minor modification) by a small margin service time of can arranging in pairs or groups let this traditional element produce with this and postpone source signal, and this point will be explained in the back more in detail.

As shown in Figure 6, after use postponed source signal, color of pixel component member just can be arranged again, particularly six the pixel P (0,0) shown in the display 600, P (0,1), P (0,2), P (1,0), P (1,1), P (1,2).For asking clear expression, shadow representation is used in the zone of the pixel of each display 600, and this shade only is used for key drawing 6, does not have the meaning on any function.

The pixel P of display 600 (0,1) comprises transistor T (0,1,1), T (0,2,2), T (0,1,3).The grid of transistor T (0,1,1), T (0,1,3) is coupled to gate lines G 1, yet the grid of transistor T (0,2,2) is coupled to gate lines G 2.Thus, the single pixel of display 600 is controlled by many gate lines.As previously mentioned, only there is a gate line to start, so the single color of pixel particle of display 600 charged in the different periods at every turn.Yet the spectators that can not be shown device 600 to the fine delay next bar gate line from arbitrary gate line perceive.

Fig. 7 illustrates a kind of time chart of simplifying with source signal S0_1, S0_2_D, S0_3, S1_1_D, S1_2, S1_3_D, and it is last that wherein these source signal put on source electrode line S0_1, S0_2, S0_3, S1_1, S1_2, S1_3 respectively.In Fig. 7, the horizontal line that is expressed as G0, G1, G2, G3 represent respectively that gate lines G 0, G1, G2, G3 start during.In addition, the preparation pixel that will write data is indicated on signal pattern inside.In addition, by source signal S0_2, S1_1, S1_3 are postponed a row to update time, just can produce source signal S0_2_D, S1_1_D, S1_3_D respectively.

As shown in Figure 7, when gate lines G 0 started, pixel P (0,0) obtained data by source electrode line S0_1, S0_3, and pixel P (1,0) obtains data by source electrode line S1_2.In addition, as shown in Figure 6, when gate lines G 0 starts, transistor T (0; 0,1) upgrade the color particle CD_1 of pixel P (0,0) by the data on the source electrode line S0_1, and transistor T (0; 0,3) upgrade the color particle CD_3 of pixel P (0,0) by the data on the source electrode line S0_3, and transistor T (1; 0,2) upgrades the color particle CD_2 of pixel P (1,0) by the data on the source electrode line S1_2.Yet when carrying out aforementioned renewal, color particle CD_1, the CD_3 of the color particle CD_2 of pixel P (0,0) and pixel P (1,0) do not upgrade with new data as yet.

When gate lines G 1 started, pixel P (0,0) obtained data by source electrode line S0_2; And pixel P (0,1) is by source electrode line S0_1, S0_3 and obtain data, and pixel P (1 again; 0) obtain data by source electrode line S1_1, S1_3, pixel P (1,1) obtains data by source electrode line S1_2 in addition.In addition, as shown in Figure 6, when gate lines G 1 starts, transistor T (0; 1,1) upgrade the color particle CD_1 of pixel P (0,1) by the data on the source electrode line S0_1, and transistor T (0; 1,2) upgrade the color particle CD_2 of pixel P (0,0) by the data on the source electrode line S0_2, and transistor T (0; 1,3) upgrades the color particle CD_3 of pixel P (0,1) by the data on the source electrode line S0_3.In addition, transistor T (1,1,1) upgrades pixel P (1 by the data on the source electrode line S1_1; 0) color particle CD_1, and transistor T (1,1; 2) upgrade the color particle CD_2 of pixel P (1,1) by the data on the source electrode line S1_2, and transistor T (1; 1,3) upgrades the color particle CD_3 of pixel P (1,0) by the data on the source electrode line S1_3.Thus, in this renewal, pixel P (0,0), all color particles of P (1,0) all are updated.Yet, so far only have the color particle of pixel P (0,1), P (1,1) part not to be updated yet.

When gate lines G 2 started, pixel P (0,1) obtained data by source electrode line S0_2; And pixel P (0,2) is by source electrode line S0_1, S0_3 and obtain data, and pixel P (1 again; 1) obtain data by source electrode line S1_1, S1_3, pixel P (1,2) obtains data by source electrode line S1_2 in addition.In addition, as shown in Figure 6, when gate lines G 2 starts, transistor T (0; 2,1) upgrade the color particle CD_1 of pixel P (0,2) by the data on the source electrode line S0_1, and transistor T (0; 2,2) upgrade the color particle CD_2 of pixel P (0,1) by the data on the source electrode line S0_2, and transistor T (0; 2,3) upgrade the color particle CD_3 of pixel P (0,2) by the data on the source electrode line S0_3.In addition, transistor T (1,2,1) upgrades pixel P (1 by the data on the source electrode line S1_1; 1) color particle CD_1, and transistor T (1,2; 2) upgrade the color particle CD_2 of pixel P (1,2) by the data on the source electrode line S1_2, and transistor T (1; 2,3) upgrade the color particle CD_3 of pixel P (1,1) by the data on the source electrode line S1_3.Thus, in this renewal, pixel P (0,0), P (1,0), P (0,1), all color particles of P (1,1) all are updated.Yet, so far only have the color particle of pixel P (0,2), P (1,2) part not to be updated yet.

Application is disclosed in structure and the method for Fig. 5-Fig. 8, Fig. 9 (a)-Fig. 9 (c), and the display with on-off element point inversion driving mechanism can be implemented by specific integrated circuit, and wherein this IC design becomes to be used for implementing the capable inversion driving mechanism of on-off element.Further; Application is disclosed in structure and the method for Fig. 5-Fig. 8, Fig. 9 (a)-Fig. 9 (c); Display with on-off element point inversion driving mechanism also can be implemented by specific integrated circuit, and wherein this IC design becomes to be used for implementing the capable inversion driving mechanism of on-off element.

In addition, use disclosed structure of the present invention and method, the display with on-off element point inversion driving mechanism can be implemented by specific integrated circuit, and wherein this IC design becomes to be used for implementing on-off element row inversion driving mechanism.Particularly, whenever making progress at a distance from a row of display, transistor and corresponding color particle are configured in an other side of source electrode line.Figure 10 illustrates the part according to the display 1000 of one embodiment of the invention.In display 1000, transistorized source electrode, grid and drain electrode are coupled to the electrode of source electrode line, gate line and color particle respectively.For asking clear expression, this with these transistors be expressed as transistor T (X, Y, Z), wherein transistor T (source electrode Z) is coupled to source electrode line SX_Z for X, Y, and transistor T (grid Z) is coupled to gate lines G Y for X, Y.Display 1000 is just that with the main difference place of display 400-430 connected mode is different, and in display 1000, these transistor may command that are coupled to the identical sources polar curve are positioned at the color particle that different lines makes progress.For example, transistor T (0,1; 2) the color particle of being controlled (can be the first color particle) is positioned at right-hand row of source electrode line S0_2 upwards; And the row that the color particle that transistor T (0,2,2) is controlled (can be the second color particle) is positioned at source electrode line S0_2 left upwards.In display 1000, when ordinal number Y was odd number, then (it is right-hand that the color particle of Z) being controlled is positioned at source electrode line SX_Z for X, Y for transistor T.When ordinal number Y was even number, then (the color particle of Z) being controlled was positioned at source electrode line SX_Z left to transistor T for X, Y.Thus, each row pixel upwards adds a horizontal particle spacing (horizontal dot spacing) (being the spacing between the color particle level) with color particle width in pixel level interval that adjacent lines make progress.For example, in pixel 1000, three color particle CD_1, CD_2, the CD_3 of pixel P (0,1) are coupled to transistor T (0,1 respectively; 1), T (0,1,2), T (0,1,3); And three color particle CD_1, CD_2, the CD_3 of pixel P (0,0) are coupled to transistor T (0,0,1), T (0 respectively; 0,2), T (0,0,3).In addition, pixel P (0,1) and pixel P (0,0) be horizontal alignment not, that is the color particle CD_1 of the color particle CD_1 of pixel P (0,1) and pixel P (0,0) be positioned at different lines to.In detail, transistor T (0,1,1) all is coupled to source electrode line S0_1 with both source electrodes of T (0,0,1).Yet the color particle CD_1 of transistor T (0,1,1) and pixel P (0,1) is positioned at the right side of source electrode line S0_1, and the color particle CD_1 of transistor T (0,0,1) and pixel P (0,0) is positioned at the left side of source electrode line S0_1.Similarly, the color particle CD_2 of transistor T (0,1,2) and pixel P (0,1) is positioned at the right side of source electrode line S0_2, and the color particle CD_2 of transistor T (0,0,2) and pixel P (0,0) is positioned at the left side of source electrode line S0_2.In addition, the color particle CD_3 of transistor T (0,1,3) and pixel P (0,1) is positioned at the right side of source electrode line S0_3, and the color particle CD_3 of transistor T (0,0,3) and pixel P (0,0) is positioned at the left side of source electrode line S0_3.As previously mentioned, when application switch element line inversion driving device, these color particles of being controlled by transistor have identical polarity, and wherein these transistors are coupled to same source electrode line.Shown in figure 10, just the polarity pattern that the color particle is constituted among Figure 10 can be identical with the polarity pattern of the display (shown in Fig. 4 (b)) that adopts on-off element point inversion driving mechanism.Yet, under the considering who saves energy and reduce cost, adopt on-off element row inversion driving device still to be worse than the capable inversion driving device of employing on-off element to implement the mode of on-off element point counter-rotating with the effect of the mode of enforcement on-off element point counter-rotating.

In the embodiment of Figure 10, the color component member in adjacent two row is also unjustified.Thus, Figure 10 adopts the color scheme of triangular form.Yet some embodiment of the present invention comprises a kind of driving mechanism of novelty, is used for arranging again these color component members to reach the color scheme of triangular form.

Particularly, Figure 11 (a) illustrates the display 1100 according to one embodiment of the invention, and wherein display 1100 adopts this novel driving mechanism.Figure 11 (a) is similar to FIG. 10, and its difference is that the source electrode data can produce skew when specific gate line starts.Particularly, time control offset units (time control shift unit) 1140a is configured in before the source electrode line, and when every gate line at a distance from started, the source electrode data can squint and input in the source electrode line of adjacency.In detail, when ordinal number was gate line (like gate lines G 0, the G2) startup of even number, the source electrode data can squint and input in the source electrode line on the source electrode line the right that originally should import.For example, source electrode data S0_1 squints and inputs to source electrode line S0_2.In addition, source electrode data S0_2, S0_3, S1_1, S1_2, S1_3 squint and input to source electrode line S0_3, S1_1, S1_2, S1_3, S2_1 respectively.When ordinal number was the gate line startup of odd number, the source electrode data just can not squint.Yet the source electrode line S0_1 of display 1100 high order ends only can receive source electrode data S0_1 forever.For asking clear expression, will extraly represent " s " through the source electrode line after the migration process, shown in source electrode line S0_2s.

Explain this shift into because of best mode be to explain Figure 10 and Figure 11 (a) simultaneously.For example, when the gate lines G among Figure 10 0 started, the data that be sent to the color particle CD_1 of pixel P (0,0) were positioned on the source electrode line S0_1, and these data can be received by transistor T (0,0,1).When gate lines G 1 started, the data that be sent to the color particle CD_1 of pixel P (0,1) were positioned on the source electrode line S0_1, and these data can be received by transistor T (0,1,1).By Figure 10 (and Figure 11 (a)) can know learn transistor T (0,0,1) not horizontal alignment in transistor T (0,1,1).Yet in Figure 11 (a), when gate lines G 0 started, the data-bias of color particle CD_1 that be sent to pixel P (0,0) was to source electrode line S0_2s, and these data can be received by transistor T (0,0,2).When gate lines G 1 started, the data that be sent to the color particle CD_1 of pixel P (0,1) were positioned on the source electrode line S0_1, and these data can be received by transistor T (0,1,1).Shown in Figure 11 (a) (and Figure 10), transistor T (0,0,2) horizontal alignment is in transistor T (0,1,1).Shown in similar reason, all color particle of pixel P (0,0) will horizontal alignment in pixel P (0,1), P (0,2) corresponding color particle.Thus, adopt the offset manner of aforementioned (also can narrate in detail more afterwards) can make each row in the display 1100 in the pixel level alignment.

Generally speaking, source electrode data SX_Y is skew and input to source electrode line SJ_Ks, and wherein J equals Y and adds X divided by 3 later integral parts, and K equals to add 1 again behind the Y congruence 3.Formula (1) and formula (2) provide the formula of J and K respectively:

J=X+1NT (Y/3) formula (1)

K=(Y MOD 3)+1 formula (2)

In other words, source electrode line SX_Y receives source electrode data SM_N, and wherein M equals X and deducts Y divided by the integral part after 3, and N equals Y and adds 1 back congruence 3 earlier, then adds 1 again.Formula (3) and formula (4) provide the formula of M and N respectively:

M=X-INT (Y/3) formula (3)

N=((Y+1) MOD 3)+1 formula (4)

Shown in Figure 11 (a), after adopting the delay source signal,, particularly will describe with six the pixel P (0,0) in the display 1100, P (0,1), P (0,2), P (1,0), P (1,1), P (1,2) just the color of pixel particle can be arranged again.For asking clear expression, shadow representation is used in the zone of each pixel, and this shade only is used to explain Figure 11 (a), does not have the meaning on any function.

Figure 11 (a) also illustrates the basic embodiment of time control offset units 1140a.Particularly, come to select the source electrode data, detail and the mode preamble of selecting is existing for source electrode line SX_Y with multiplexer (Multiplexer) MXY.When ordinal number was the gate line startup of even number, the control end (not shown) of each multiplexer just can receive enabling signal, and when ordinal number was the gate line startup of odd number, the control end of multiplexer just can be in the state of non-startup (inactive).

Figure 11 (c) is the simplification calcspar according to the display 1101b of another embodiment of the present invention.Display 1101b is similar with display 1101a and adopt identical member, its difference only to be that display 1101b will control offset units 1140a the time and replace to time control offset units 1140b.For asking narration to simplify, the member that display 1101b is identical with display 1101a just repeats no more.In display 1101b, make row driver 930 directly drive all source electrode lines of liquid crystal cells 910 by removing time control offset units 1140a.Yet control offset units 1140b setup time between time controller 915 and row driver 930.Particularly, time control offset units 1140b can squint the column data C_DATA that sends from time controller 915, is sent to the offset column data SC_DATA of row driver 930 with generation.Thus, row driver 930 still can provide the offset source number of poles to the source electrode line of liquid crystal cells 910 according to SS_DATA.

Figure 11 (d) is the simplification calcspar according to the display 1101c of yet another embodiment of the invention.Display 1101c is similar with display 1101a and adopt identical member, its difference only to be that display 1101c will control offset units 1140a the time and replace to time control offset units 1140c.For asking narration to simplify, the member that display 1101c is identical with display 1101a just repeats no more.In display 1101c, make row driver 930 directly drive all source electrode lines of liquid crystal cells 910 by removing time control offset units 1140a.Yet control offset units 1140c setup time between time controller 915 and video data generator 905.The video data D_DATA of part can be controlled offset units 1140c skew to produce skew video data SD_DATA by the time.Other video data D_DATA and delay video data DD_DATA can be provided to time controller 915, and time controller 915 produces offset column data SC_DATA for row driver 930, and produce column data R_DATA for line driver 920.Particularly, counterpart capable to video data can be squinted.Because these skew video datas, so row driver 930 will the offset source number of poles number of it is believed that DS_DATA provides the source electrode line to the liquid crystal cells 910.

As previously mentioned, an advantage of the present invention is by time control offset

units

1140a, 1140b, 1140c and is applied to the conventional components that on-off element is listed as the counter-rotating display, just can create on-off element point counter-rotating display.Yet for reducing the member cost, time control offset units can be integrated with the described one or more members of Figure 11 (b)-11 (d).For example; Time control offset units 1140a can integrate with row driver 930; And time control offset units 1140b can integrate with time controller 915 or row driver 930, and time control offset units 1140c can integrate with time controller 915 or video data generator 905.Generally speaking, will control the cost that offset units is integrated in time controller 915 or the video data generator 905 time and will be integrated in the cost in the row driver 930 less than controlling offset units the time.

For example, Figure 12 (a) illustrates the sub-fraction (six pixels) of display 1200, and wherein display 1200 adopts the horizontal stripe colored filter to arrange.Particularly, Figure 12 (a) comprises pixel P (0,0), P (1,0), P (2,0), P (3,0), P (4,0), P (5,0), and each pixel comprises three color particle CD_1, CD_2, CD_3 and three transistors.These color particles in the pixel 1200 are homeotropic alignments, and the display 400 that is different from Fig. 4 (a) adopts horizontally.In addition, the color component member between different pixels is horizontal, that is display 1200 adopts the horizontal stripe colored filter to arrange.Figure 12 (a) also comprises source electrode line S0, S1, S2, S3, S4, S5 and gate lines G 0_1, G0_2, G0_3, G0_4.Generally speaking, source electrode line SX is corresponding with gate lines G Y_Z act on pixel P (X, on color particle CD_Z Y), and pixel P (X Y) promptly is X pixel on Y is capable.Transistorized source electrode, grid and drain electrode are coupled to the electrode of source electrode line, gate line and color particle respectively.For asking clear expression, this with these transistors be expressed as transistor T (X, Y, Z), wherein transistor T (source electrode Z) is coupled to source electrode line SX for X, Y, and transistor T (grid Z) is coupled to gate lines G Y_Z for X, Y.In display 1200, (drain electrode Z) is coupled to pixel P (X, color particle CD_Z Y) to transistor T for X, Y.For example, three color particle CD_1, CD_2, the CD_3 of pixel P (1,0) are coupled to transistor T (1,0,1), T (1,0,2), T (1,0,3) respectively.Transistor T (1,0,1), T (1,0,2), T (1,0; 3) source electrode is coupled to source electrode line S1, and transistor T (1,0,1), T (1,0,2), T (1; 0,3) grid is coupled to gate lines G 0_1, G0_2, G0_3 respectively, and transistor T (1,0,1), T (1; 0,2), the drain electrode of T (1,0,3) is coupled to color particle CD_1, CD_2, the CD_3 of pixel P (1,0) respectively.For asking clear expression, shadow representation is used in the zone of each pixel, and this shade only is used to explain Figure 12 (a), does not have the meaning on any function.

Each bar source electrode line extends to the base from the top margin of display 1200, and same all pixels that list in the control display 1200, and for arbitrary pixel that lists, display 1200 can have corresponding source electrode line.In addition; Each bar gate line extends to the right from the left side of display 1200; And display 1200 has many gate lines, and wherein the quantity of gate line is three times (that is color component members of a corresponding pixel of gate line) that list pixel quantity arbitrary.When display is operated, only there is a gate line to start at every turn.In addition, all source electrode lines all can start simultaneously, and every source electrode line can provide image data to the transistor that starts on the row, wherein start row by starting gate line control.

The display of similar use vertical stripes colored filter, the display of usage level striped colored filter also can adopt different on-off element driving mechanisms.Three kinds of main on-off element driving mechanisms are respectively on-off element point inversion driving mechanism, the capable inversion driving mechanism of on-off element and on-off element row inversion driving mechanism.Figure 12 (b) illustrates display 1210, and wherein display 1210 has the basic layout identical with display 1200, and display 1210 adopts on-off element point inversion driving machine-processed.In Figure 12 (b), when ordinal number X added that ordinal number Y adds ordinal number Z (being X+Y+Z) for odd number, then (X, color particle CD_Z Y) had positive polarity (being expressed as "+") to pixel P.On the contrary, when ordinal number X added that ordinal number Y adds ordinal number Z (being X+Y+Z) for even number, then (X, color particle CD_Z Y) had negative polarity (being expressed as "-") to pixel P.Yet when changing to next figure frame, all color particles all can switch polarity and the polarity of changeabout.

In the capable inversion driving mechanism of on-off element, have identical polarity with the on-off element in the delegation, but the polarity of on-off element can be opposite with the polarity of on-off element on the adjacent lines on arbitrary row.Figure 12 (c) is that illustration goes out the capable inversion driving mechanism of on-off element with display 1220, and wherein display 1220 has identical basic layout with display 1200.In Figure 12 (c), when ordinal number Y added ordinal number Z and is even number, then (X, color particle CD_Z Y) had positive polarity to pixel P.On the contrary, when ordinal number Y added ordinal number Z and is odd number, then (X, color particle CD_Z Y) had negative polarity to pixel P.Yet when changing to next figure frame, all color particles all can switch polarity and the polarity of changeabout.

In on-off element row inversion driving mechanism, the same on-off element that lists has identical polarity, but arbitrary polarity that lists on-off element can be opposite with the polarity of on-off element on the adjacent columns.Figure 12 (d) is that illustration goes out on-off element row inversion driving mechanism with display 1230, and wherein display 1230 has identical basic layout with display 1200.In Figure 12 (d), when ordinal number X was even number, then (X, color particle CD_Z Y) had positive polarity to pixel P.On the contrary, when ordinal number X was odd number, then (X, color particle CD_Z Y) had negative polarity to pixel P.Yet when changing to next figure frame, all color particles all can switch polarity and the polarity of changeabout.

As previously mentioned; Compare with on-off element row inversion driving mechanism with the capable inversion driving mechanism of on-off element; On-off element point inversion driving mechanism provides better image quality, but the cost that will implement out driver that on-off element point reverses and various members is expensive many.Thus, the present invention can adopt driver and the member of lower cost to implement out on-off element point inversion driving mechanism, and it is machine-processed that wherein the driver of these lower costs and member should be used for the capable inversion driving of on-off element.

Figure 13 illustrates according to the sub-fraction of the display 1300 of one embodiment of the invention (six pixels).Particularly, Figure 13 illustrates the part of pixel P (0,0), P (1,0), P (2,0), P (3,0), P (4,0), P (5,0) and pixel P (1,1), P (3,1), and each pixel comprises three color particle CD_1, CD_2, CD_3 and three transistors.Figure 13 also comprises source electrode line S0, S1, S2, S3, S4, S5 and gate lines G 0_1, G0_2, G0_3, G0_4.Each bar gate line extends to the right from the left side of display 1300.Only can control the color particle that makes progress with delegation with the gate line of display 1200-1230 and compare, the color particle that the gate line of display 1300 is controlled can be positioned at and surpass more than one row upwards, and this preamble all details.In addition, each bar source electrode line extends to the base from the top margin of display 1300.Display 1300 has many gate lines, and wherein the quantity of gate line is three times (that is color component members of a corresponding pixel of gate line) at arbitrary pixel quantity that lists.When display is operated, only there is a gate line to start at every turn.All crystals pipe starting on the row will present the state of conducting by the forward grid impulse that starts gate line, then can present the state that opens circuit because putting on the negative voltage on the non-startup gate line as for the transistor on other row.In addition, all source electrode lines all can start simultaneously, and every source electrode line can provide image data to the transistor that starts on the row, wherein start row by starting gate line control.Voltage can charge to a specific GTG with liquid crystal capacitance, and produces color by colored filter.

In display 1300, transistorized source electrode, grid and drain electrode are coupled to the electrode of source electrode line, gate line and color particle respectively.For asking clear expression, this with these transistors be expressed as transistor T (X, Y, Z), wherein transistor T (source electrode Z) is coupled to source electrode line SX for X, Y, and transistor T (grid Z) is coupled to gate lines G Y_Z for X, Y.Display 1300 is just that with the main difference part of display 1200-1230 connected mode is different, and in display 1300, these transistor may command that are coupled to identical gate line are positioned at the color particle that different rows makes progress.For example, transistor T (0,0; 2) row that the color particle of being controlled (can be the first color particle) is positioned at gate lines G 0_2 top makes progress; And the row that the color particle that transistor T (1,0,2) is controlled (can be the second color particle) is positioned at gate lines G 0_2 below upwards.In display 1300, when ordinal number X added that ordinal number Z is even number, then (X, Y, the color particle of Z) being controlled were positioned at transistor T (X, Y, Z) top to transistor T.When ordinal number X added that ordinal number Z is odd number, then (X, Y, the color particle of Z) being controlled were positioned at transistor T (X, Y, Z) below to transistor T.Thus; When gate lines G 0_2 starts; The color particle that these row that are positioned at gate lines G 0_2 top make progress comes the first color particle to begin the color particle in every interval from the left number just can to start, and the color particle that makes progress of these row that are positioned at gate lines G 0_2 below comes the second color particle to begin the color particle in every interval from the left number just can to start.As previously mentioned, when application switch element row inversion driving device, these color particles of being controlled by transistor have identical polarity, and wherein these transistors are coupled to same gate line.Shown in figure 13, just the polarity pattern of the display (shown in Figure 12 (b)) that the polarity pattern that is constituted at the color particle among Figure 13 can be machine-processed with adopting on-off element point inversion driving is identical.

Because the transistorized connected mode of display 1300 changes, thus in the display 1300 adjacent two row to pixel and unjustified.For asking clear expression, shadow representation is used in the zone of the pixel of each display 1300, and this shade only is used to explain display 1300, does not have the meaning on any function.In display 1300, pixel P (0,0) comprises three color particle CD_1, CD_2, CD_3, and these three color particles are coupled to transistor T (0,0,1), T (0,0,2), T (0,0,3) respectively.In addition, pixel P (1,0) also comprises three color particle CD_1, CD_2, CD_3, and these three color particles are coupled to transistor T (1,0,1), T (1,0,2), T (1,0,3) respectively.Yet pixel P (0,0) and pixel P (1,0) be vertical alignment not.Particularly, pixel P (1,0) is than the low color particle height of pixel P (0,0).In display 1300, ordinal number be the row of even number to meeting skew ordinal number be the row of odd number to surpassing a color particle height, and this adjacent columns to vertical shift can avoid the color component member of neighbor horizontal.Thus, display 1300 adopts staggered colored filter configuration, but not the configuration of horizontal stripe colored filter.

The driving mechanism of the aforementioned novelty shown in Fig. 6, Fig. 7, Fig. 8, Fig. 9 (a)-Fig. 9 (c) can be used for arranging again these pixels, to reach the configuration of horizontal stripe colored filter.Figure 14 illustrates the display 1400 according to this novel driving mechanism of application of one embodiment of the invention.Figure 14 is similar with Figure 13, and its difference only is that some signal that puts on the source electrode line that ordinal number is an odd number can be postponed, so similarly explanation just no longer repeats.Particularly, postponing source signal S1_D, S3_D, S5_D, to put on source electrode line S1, S3, S5 respectively last.In one embodiment of this invention, postponing source signal is to produce via the delay circuitry in the time controller.In another embodiment of the present invention, an independent time control lag unit collocation is used at source electrode line S1, S3, S5 last (like the use-pattern of Figure 13), and this timing period equals single row during upgrading.Like preceding detailed explanation, the traditional element control lag unit or change by a small margin service time of can arranging in pairs or groups postpones source signal thereby let this traditional element produce.

Shown in figure 14, after using the delay source signal, color of pixel component member just can be arranged again, particularly six the pixel P (0,0) shown in the display 1400, P (1,0), P (2,0), P (3,0), P (4,0), P (5,0).For asking clear expression, shadow representation is used in the zone of each pixel, and this shade only is used to explain Figure 14, does not have the meaning on any function.Thus, display 1400 adjacent two row in pixel just can vertical alignment.In addition, also can align with delegation's color of pixel component member that makes progress.So display 1400 adopts the configuration of horizontal stripe colored filter.

On-off element point inversion driving mechanism is implemented out in the display explanation of Figure 14 by specific integrated circuit, wherein this IC design becomes to be used for implementing the capable inversion driving mechanism of on-off element.Like the display 500 of earlier figures 5, just the polarity pattern that the color particle among Figure 14 is constituted can be identical with the polarity pattern of the display that adopts on-off element point inversion driving mechanism.

Implement on-off element point inversion driving mechanism with specific integrated circuit, if wherein this IC design becomes to be used for implementing the capable inversion driving mechanism of on-off element, then the layout of Figure 13 (layout) just converts staggered color scheme to by the striped color scheme.Using the display of striped pattern color configuration, some embodiment of the present invention comprises that a kind of novel driving mechanism arranges to promote color, and this novel driving mechanism postpones source signal with color-arranged component member again.
