Embodiment
Below, with reference to description of drawings example of the present invention.Fig. 1 is the block diagram of structure of the electro-optical device 10 of this example of expression.
As shown in the figure, this electro-optical device 10 has control circuit 12, storer 13, Y driver 14, X driver 16 and light source 18, and simultaneously, transversely (directions X) is provided with 360 horizontal scanning lines 112, (Y direction) is provided with 480 column data lines 114 on the other hand, along the longitudinal.And, the corresponding arrangement of respectively reporting to the leadship after accomplishing a task of pixel 100 and these sweep traces 112 and data line 114.Thereby in this example, pixel 100 is arranged in the rectangular of vertical 360 row * horizontal strokes, 480 row, forms viewing area 100a.
This viewing area 100a becomes the device substrate that has formed pixel electrode and keeps certain clearance to bond together mutually with the transparent relative substrate with common electrode, and liquid crystal is clipped in structure in this gap.
Here, video data Data is the data according to the brightness (gray-scale value) of every kind of primary colors specified pixel of RGB.In this example, as described later, 1 vertical scanning period (1 frame) is divided into every kind of look continuous field of RGB, and then each is divided into the 1st son field and the 2nd son field, in the 1st and the 2nd sub, and the vertical scanning difference of viewing area 100a.Therefore, control circuit 12 becomes after the storage 1 frame part, in each son field, reads the video data of corresponding colouring component to the video data Data from the upper level unit feeding at least storer 13, supply to the structure of X driver 16.In addition, control circuit 12 is controlled for luminous the extinguishing also of all kinds that is undertaken by light source 18 described later.
The detailed operation of Y driver (scan line drive circuit) 14 is narrated in the back, and this is a circuit of supplying with sweep signal in each sweep trace 112 of 1～360 row, and is corresponding with the 1st and the 2nd son field, according to predetermined each sweep trace 112 of select progressively.Here, among the figure sweep signal that supplies to the 1st row～the 360 horizontal scanning line 112 is designated as Y respectively
-1, Y
-2, Y
-3..., Y
-360
X driver (data line drive circuit) 16 is transformed to the data-signal of the voltage that is suitable for driving liquid crystal to the video data of the 1 row pixel portion that is positioned at selected sweep trace 112, supplies to pixel 100 through data line 114 respectively.Here, among the figure data-signal that supplies to the 1st row～the 480 column data line 114 is designated as X respectively
-1, X
-2, X
-3..., X
-480
Light source 18 is the so-called back light units that comprise red LED 18R, green LED 18G, blue led 18B, for viewing area 100a, shines the light of a certain look of red (R), green (G), blue (B) equably.Here, luminous by each LED in the control circuit 12 control light sources 18.
Secondly, with reference to the structure of Fig. 2 pixels illustrated 100.
As shown in the drawing, in pixel 100, the source electrode of n channel-type TFT (thin film transistor (TFT)) 116 connects data line 114, and simultaneously, drain electrode connects pixel electrode 118, and on the other hand, grid connects sweep trace 112.
In addition, make relatively, simultaneously, in this example, apply certain voltage LCcom by the time with pixel electrode 118 for the shared common electrode 108 of being provided with of all pixels.And, liquid crystal layer 105 is clipped between these pixel electrodes 118 and the common electrode 108.Thereby,, constitute the liquid crystal capacitance that forms by pixel electrode 118, common electrode 108 and liquid crystal layer 105 in each pixel.
Though do not illustrate especially, yet on each opposite face of two substrates, respectively friction treatment is set alignment films, make long axis direction for example about 90 degree distortion continuously between two substrates of liquid crystal molecule, on the other hand, each back side one side at two substrates is provided with the polarizer that makes the axis of homology consistent with direction of orientation respectively.
Therefore, if the voltage effective value that is applied on the liquid crystal capacitance is 0, then owing to carry out about 90 degree optically-actives along the distortion of liquid crystal molecule by the light between pixel electrode 118 and the common electrode 108, so optical transmission rate maximum, on the other hand, along with this voltage effective value increases, the result that liquid crystal molecule tilts to direction of an electric field, its optical activity disappears, so the minimizing of the light quantity of transmission, and transmissivity becomes minimum (normal white mode) gradually.
Thereby,, watch by the user under in each pixel from the emergent light of light source 18 by the state that is applied to the voltage effective value restriction on the liquid crystal capacitance, thus, can realize that so-called gray scale shows.
In addition, in order to reduce influence, form memory capacitance 109 in each pixel from the charge leakage of the liquid crystal capacitance that has passed through TFT116.One end of this memory capacitance 109 connects pixel electrode 118 (drain electrode of TFT116), and on the other hand, the other end spreads all over whole pixels, and for example shared grounding is to the current potential Vss of electronegative potential one side of power supply.
Secondly, the work of the electro-optical device 10 of this example is described.Fig. 3 is the sequential chart of the vertical scanning work of expression electro-optical device 10.
As shown in the drawing, in this example, 1 vertical scanning period (1 frame) is divided into corresponding 3 fields with RGB, and then each is divided into the 1st and the 2nd son field.
Here, in 1 vertical scanning period, in the 1st son field of R field, control circuit 12 is controlled to feasible all LED that extinguishes for light source 18, simultaneously, with in Fig. 1 from top several odd line interlace line 112 and with this odd line interlace line below 2 row of adjacent even number line sweep trace 112 as 1 group, at each horizontal scan period (1H), sequentially select like that control Y driver 14 from top beginning.
Thus, as shown in Figure 3, in initial 1 horizontal scan period (1H) in the 1st son field of R field, has only sweep signal Y
-1, Y
-2Become H (height) level simultaneously, then, have only sweep signal Y
-3, Y
-4Become the H level simultaneously, and then, have only sweep signal Y
-5, Y
-6Become the H level simultaneously, same later on, the sweep signal of odd-numbered line and the even number line that is connected on odd-numbered line back order simultaneously becomes the H level, and is final, sweep signal Y
-359, Y
-360Become the H level simultaneously.
Thus, X driver 16 is exported the data-signal X of the pixel column that is positioned at odd-numbered line respectively for corresponding data line 114 in selected 2 row
-1, X
-2, X
-3..., X
-480, that is, and with the data-signal of the corresponding voltage of gray scale of R component.
Here, at the sweep trace 112 of selecting certain odd-numbered line, its sweep signal becomes under the situation of H level, owing to be positioned at the TFT116 conducting of pixel 100 of the sweep trace 112 of selected odd-numbered line, therefore when being conceived to a certain column data line 114, in the sweep trace 112 that this voltage of having the data-signal of row in mind is written to and selects and the pixel electrode 118 of the corresponding pixel of reporting to the leadship after accomplishing a task of the data line 114 of having row in mind.Wherein, in this example, when having selected odd-numbered line, owing to also select the sweep trace 112 of the even number line adjacent with its below simultaneously, so this voltage of having the data-signal of row in mind also is written to the sweep trace 112 of selected even number line and has in mind in the pixel electrode 118 of the corresponding pixel of reporting to the leadship after accomplishing a task of data line 114 of row.
Thereby, when the selection of sweep trace, if select simultaneously odd-numbered line sweep trace 112 and with the sweep trace 112 of its adjacent even number line in below, then with their corresponding 2 pixels 100 in, owing to write identical data-signal, therefore the transmission amount of these two pixels is corresponding with the voltage of this data-signal, becomes identical value.Therefore, when finishing, shown in Fig. 5 (a), in odd-numbered line and the even number line below it, so become identical gray scale at each broomrape and show in the 1st son field of R field.Wherein, finishing up to the 1st son field of R field, in light source 18, owing to extinguish all LED, therefore only is that the show state that writes formation of the 1st son field can't the observed person be watched.
Then, in the 2nd son of R field, control circuit 12 is controlled to for light source 18 and makes and only to make red LED 18R luminous that simultaneously, control Y driver 14 makes at each horizontal scan period (1H), from the sweep trace 112 of top beginning select progressively even number line.
Thus, as shown in Figure 3, in initial 1 horizontal scan period (1H) in the 2nd son field of R field, only be scanning wire size Y
-2Becoming the H level, in next horizontal scan period, only is sweep signal Y
-4Become the H level, same later on, sweep signal Y
-360Become the H level.
The control circuit 12 control Y drivers 14 feasible sweep traces 112 of only selecting even number line on the other hand, are controlled X driver 16 as described below.That is, control circuit 12 for X driver 16, is controlled to the data-signal of 1 row pixel portion of the sweep trace 112 that makes output together be positioned at selected even number line when the selection of each sweep trace.
Thus, the X driver is exported the data-signal X that is positioned at selected even number line pixel column respectively for corresponding data line 114
-1, X
-2, X
-3..., X
-480
Here, at the sweep trace 112 of selecting certain even number line, its sweep signal becomes under the situation of H level, when being conceived to certain column data line 114, this voltage of having the data-signal of row in mind is written to and selects in the pixel electrode 118 of the sweep trace 112 and the corresponding pixel of reporting to the leadship after accomplishing a task of the data line 114 of having row in mind.
On the other hand, in the pixel of odd-numbered line, do not write owing in the 2nd son field, do not carry out, so keep by the 1st sub the voltage that writes.
Thereby, when the 2nd son of R field finishes, shown in Fig. 5 (b), in odd-numbered line, keep by the gray scale that writes generation in the 1st son, on the other hand, in even number line, become the gray scale that the 2nd time of being undertaken by the 2nd son field writes generation.
Here, in the 2nd son field,, keep becoming original gray scale by writing in the 2nd son field by the gray scale that writes generation in the 1st son field because red LED 18R is luminous, so for even number line, writes up to finishing.Therefore, by top row, the ratio of watching with original gray scale is high more more, and for becoming following row, the ratio of watching with original gray scale is low.But if on average watch, then in even number line, the ratio of watching with original gray scale roughly becomes half, in odd-numbered line, finishes owing to write in the 1st son field originally, watch with original gray scale, so the reduction of resolution can not become problem.
In this example, even finish in the selection of the even number line to the 2nd son of R field, in the retrace interval till the next G of the beginning field, control circuit 12 is controlled to also that to make that red LED 18R continues luminous.
Like this, in the 2nd son field and retrace interval subsequently of R, in full-color image, watch the image of R component by the observer.
Secondly, the G field is described.The R field is the work that writes based on the data-signal of the video data Data of R component, and the G field is the work that writes based on the data-signal of the video data Data of G component, becomes the work identical with the R field.
Thereby, in the 1st son field of G field, extinguish all LED, sequentially select 112 liang of row of sweep trace of odd number and even number line from top beginning, according to the video data of the pixel that is positioned at selected odd-numbered line pixel column, write data-signal with the corresponding voltage of gray scale of G component.Then, in the 2nd son, just green LED 18G is luminous, begins just sequentially to select the sweep trace 112 of even number line from above, in the pixel column of selected even number line, writes the data-signal with the corresponding voltage of gray scale of G component.Therefore, in the 2nd son field and retrace interval subsequently of G, in full-color image, watch the image of G component by the observer.
Also identical about the B field of following, execution writes the work based on the data-signal of the video data Data of B component.Promptly, in the 1st son field of B field, all LED extinguish, sequentially select 112 liang of row of sweep trace of odd-numbered line and even number line from top beginning, video data according to the pixel of the pixel column that is positioned at selected odd-numbered line, write data-signal with the corresponding voltage of gray scale of B component, then, in the 2nd son field, only light blue led 18B, sequentially only select the sweep trace 112 of even number line from top beginning, in the pixel column of selected even number line, write data-signal with the corresponding voltage of gray scale of B component.Therefore, in the 2nd son field and retrace interval subsequently of B, in full-color image, watch the image of B component by the observer.
Thereby, in the son of R, G, B, owing to generate the primary colour image of R component, G component, B component respectively,, then watch the full-color image that has synthesized by the observer if therefore watch at 1 frame.
Like this, if according to this example, then in the 1st son field, by selecting sweep trace 112 simultaneously at per two row, select the mode in the past (with reference to Fig. 7) of 1 horizontal scanning line to compare with each, can approximately shorten half during writing needed the writing of data-signal with the corresponding voltage of gray scale of each chrominance component of RGB.Therefore, in this example, even the R field during length identical, also can guarantee the 2nd sub-field period more longways.And, in this example,, make a certain look LED luminous owing to spread all over the 2nd son and retrace interval, therefore compare between the lengthening light emission period with mode in the past, its result can carry out brighter demonstration.
At this moment,,, therefore in each zoning, there is not the different undesirable situation of brightness, in addition, do not need the complexity control of the light source of each zoning because bright 1 of a kind of color dot gets final product about the LED of all kinds in the light source 18.And then the structure of lighting device is also uncomplicated.
And in above-mentioned example, adopting the data-signal that is written in 2 row in the 1st son field is the signal of odd-numbered line, in the 2nd sub, make the LED of the look that is written into luminous, simultaneously, for the pixel of the even number line of select progressively, write the structure of the data-signal of identical colouring component.If fix this relation, then the grade of the pixel of even number line is poorer than the pixel of odd-numbered line usually.
Therefore, as shown in Figure 4, also can adopt in the 1st son field, the data-signal that is written to 2 row is taken as the signal of even number line, in the 2nd son field, be provided with and only sequentially select odd-numbered line, write the frame of the data-signal of selected odd-numbered line, with the structure of mutual frame shown in Figure 3 repeatedly of certain cycle and frame shown in Figure 4.
Here, from the viewpoint that prevents that liquid crystal from worsening, data-signal is a benchmark with the voltage LCcom that is applied on the common electrode 108, according to low level voltage and high-order voltage overturn alternately (AC driving), if the cycle of the cycle of this AC driving and mutual frame shown in Figure 3 repeatedly and frame shown in Figure 4 is consistent, then the polarity that writes of the scan line that writes in the 2nd son field promptly writes polarity owing to be fixed in odd-numbered line and even number line by what the observer watched, therefore might become the reason of so-called flicker.Thereby, we can say that the inconsistent structure of cycle of cycle of making AC driving and mutual frame shown in Figure 3 repeatedly and frame shown in Figure 4 is the most desirable.
In addition, in example, in the 1st son field, employing is selected 2 horizontal scanning lines 112 simultaneously from top beginning, selects simultaneously more than 3 row and also can adopt, simultaneously, supply with the data-signal of selected a certain pixel column, on the other hand, the pixel column of data-signal is not supplied with in select progressively in the 1st son field in the 2nd son field, supplies with the structure of data-signal in selected sweep trace again.
As mentioned above, in the 2nd son, sequentially selecting from the top down under the situation of sweep trace, Shang Mian the row ratio of watching with original gray scale is high more, along with becoming following row, and the ratio reduction of watching with original gray scale.
Therefore, in the 2nd son field of certain frame, the pixel column of data-signal is not supplied with in select progressively in the 1st son field from the top down, in the 2nd sub of other frame, and also select progressively from bottom to top conversely.
And then, also can prepare the order of multiple choices in advance, employing is not supplied with the structure of the pixel column of data-signal according to a certain select progressively of being prepared in the 1st son, remove according to the position of pixel column and the dependent status that reduces with the ratio that original gray scale is watched.
In addition, in above-mentioned example, remove beyond the 2nd son field, in retrace interval, also make the LED of a certain look luminous, and if just luminous in the 2nd son just can access sufficient brightness, extinguish in then also can be during a whole period of retrace interval or a part.
In addition, in above-mentioned example, illustrated under the little situation of the effective value of the voltage of common electrode 108 and pixel electrode 118 and carried out the normal white mode that white shows, and also can adopt the normal black pattern of carrying out black display.
In addition, in example, used the TN type as liquid crystal, and the bistable typing that also can use BTN (bistable twisted to row) the strong dielectric type of type etc. to have memory property, high-molecular dispersed, perhaps in the liquid crystal (master) of certain molecules align, dissolve and have anisotropic dyestuff (guest) aspect the absorption of visible light, the liquid crystal such as GH (host and guest) type that dye molecule and liquid crystal molecule are arranged in parallel along the long axis direction and the short-axis direction of molecule.
In addition, also can adopt when not applying voltage, liquid crystal molecule is vertically arranged for 2 substrates, on the other hand, and when applying voltage, the so-called vertical orientated structure that liquid crystal molecule is arranged along horizontal direction for 2 substrates, can also adopt when not applying voltage, liquid crystal molecule is arranged along horizontal direction for 2 substrates, on the other hand, when applying voltage, the structure that so-called parallel (level) that liquid crystal molecule is arranged along vertical direction for 2 substrates is orientated.Like this, in the present invention,, can be suitable for various situations as liquid crystal or aligned.
Secondly, the example that electro-optical device 10 as described above is used for concrete electronic equipment is described.Fig. 6 is the oblique view that expression is useful in above-mentioned electro-optical device 10 structure of the portable telephone in the display unit.
Among the figure, portable telephone 1200 is removed beyond a plurality of action buttons 1202, with receiving mouth 1204, mouth piece 1206, possesses electro-optical device 10.In addition, as electronic equipment, remove with reference to beyond Fig. 6 explanation, can also enumerate LCD TV, direct viewing type devices such as the tape video camera of find a view type or monitor direct viewing type, guider, pager, electronic notebook, desktop computer, word processor, workstation, videophone, POS terminal, touch-screen, perhaps form and amplify the porjection type devices such as projector of projection downscaled images etc.
