Display device and driving method thereof and display controller device

Invention field

The present invention relates to be provided with display device and the driving method and the display controller device of pixel at each intersection point of many signal line and multi-strip scanning line.

Background of invention

In recent years, the equipment that personal computer and TV (TV) etc. have display frame generally has the feature thin, light, that power consumption is low, and extensively utilizing with LCD (LCD) is the flat-panel monitor of representative.During this,, research and develop thin film transistor energetically owing to can obtain not have the good display image of crosstalking between neighbor.

As shown in Figure 6, general thin film transistor 211 have many signal line of comprising SL (SL1 ..., SL n), multi-strip scanning line GL (GL1 ..., GL m) and each intersection point that is located at these signal wires SL and sweep trace also line up a plurality of pixels 216 of array-like simultaneously ... display board 212, drive the signal-line driving circuit 214 of many signal line SL and drive the scan line drive circuit 213 of multi-strip scanning line GL.

Described signal-line driving circuit 214 is at each horizontal scanning period, and the view data DT that the outside is supplied with successively is transformed into parallel mode, and the view data of the 1 horizontal pixel array share that will obtain thus again is transformed into aanalogvoltage respectively, supplies with each signal wire SL.Scan line drive circuit 213 is supplied with and is selected signal voltages, so as 1 vertical cycle one by one or many select multi-strip scanning line GL by group successively.

With reference to Figure 15 described view data DT is described.Supply with signal from external tuner 150, DVD device 151 and VTR device 152 etc. with the form of vision signals such as NTSC, and after it being transformed into the display control signal of compositions such as view data DT and clock signal clk and synchronizing signal SYCN in video source 153, supply with the signal-line driving circuit 214 of thin film transistors 211 with control device 215 through demonstration shown in Figure 6.Omit signal-line driving circuit 214 among Figure 15.

Show with control device 215 described signal-line driving circuit 214 of control and scan line drive circuits 213.Show with 215 pairs of signal-line driving circuits of control device 214 and supply with view data DT, source electrode synchronizing signal SSP and source electrode clock signal SCK, scan drive circuit 213 is supplied with grid synchronizing signal GSP and gate clock signal GCK.And, show with control device 215 common built-in a plurality of line storages, so that the form of view data DT has been transformed into output usefulness from input.

, this demonstration control device of the indivedual exploitations of exploring degree that in the past cooperated thin film transistor etc.Its main cause is that the memory capacity of built-in line storage is with exploring degree difference.

The act object lesson is illustrated: use under the situation of control device in the demonstration of XGA (1024 * 768) usefulness, can constitute line storage with 1024 words, and the demonstration of HDTV (1920 * 1080) usefulness needs 1920 words with control device, differs nearly 1 times.Use control device though available LSI constitutes demonstration, the ratio that line storage accounts in the circuit scale of this LSI is big, determines the cost (chip size) of LSI according to the memory capacity of built-in line storage.

Therefore, even the greatly different demonstration of intensive exploring degree is with control device (being unified into maximum exploring degree), also be difficult to find because of cooperating maximum exploring degree to determine the cost advantage that the memory capacity universalization brings, so present situation for each exploring degree is developed, does not add unification.

On the other hand, disclose a kind of method in Japan's publication application publication " the flat 8-211846 of patent disclosure number (on August 20th, 1996 is open) ": in the one-tenth piece Driving technique that each horizontal pixel array partition is become the individual block of pixels of N (N is equal to or greater than 2 integer) drive, importing 2 pixels, output 2 pixels carries out under the situation that high-resolution shows, 2 the source electrode driver unit adjacent with picture drive, and the memory space of line storage is reduced.When high-resolution shows that the demonstration of usefulness is adopted the method with control device, can reduce the memory space of required line storage, thereby can show that the demonstration of usefulness is comprehensive with control device with low exploring degree.

Yet, the technology that the flat 8-211846 communique of patent disclosure discloses, it consists of adjacent source electrode driver and connects data bus, so be limited to the source circuit plate that forms source electrode driver and be 1 situation, can not be used for Japan's publication communique for example " the flat 10-105131 of patent disclosure number (on April 24th, 1998 is open) " and wait the own scale of putting down in writing of display board big, thereby the source circuit plate is divided in the structure of polylith (reference).

Embodiment

Embodiment 1

Illustrate that according to Fig. 1 to Fig. 5 an embodiment of the present invention is as follows.

As mentioned before, in the prior art, even use 2 demonstration control device that low exploring degree XGA plate is used in the high-resolution HDTV plate, can not be put to practicality, its reason is that existing demonstration is separate with control device, does not have the mechanism of interchange of data.

Therefore, among the present invention, be taken as between the display controller device structure of swap data mutually.Like this, the display controller device that 2 low exploring degree XGA plates are used can be used for high-resolution HDTV plate, and be put to practicality, obtain the unified cost advantage of bringing.It is the XGA plate that low exploring degree plate is shown here, the example when the high-resolution plate is the HDTV plate.

Fig. 1 illustrates the composition of the display controller device 1 of an embodiment of the present invention.Display controller device 1 mainly has input part 2, input and output portion 4, row storage part 5 and control part 3.

Input part 2 is accepted the data input from the outside of display controller device 1, and together with view data DT, input represents that the demonstration of effective period allows signal DE and clock signal clk together.These show that allowing signal DE and clock signal clk is display control signal.Allow signal DE and clock signal clk to output to capable storage part 5 and input and output portion 4 these view data DT, demonstrations that are input to input part 2, shown in thick arrow No.1 10,11.Controlled 3 control of the switching of output place, in the XGA time spent that this display controller device 1 is used as low exploring degree, the storage part 5 of only going is output place.In the HDTV time spent that this display controller device 1 is used as high-resolution, row storage part 5 and input and output portion 4 timing in accordance with regulations alternately become output place.

Input and output portion 4 has as the function of input part with as these two kinds of functions of function of efferent, and utilizes the control of control part 3, handoff functionality selectively.Input and output portion 4 is when working as efferent, and view data DT, demonstration that input part 2 is sent allow signal DE and clock signal clk to output to the outside of display controller device 1.On the other hand, when input and output portion 4 works as input part, acceptance allows signal DE and clock signal clk from view data DT, the demonstration of the outside of display controller device 1, and with these view data DT of outside input, show and allow signal DE and clock signal clk to deliver to capable storage part 5, shown in thick arrow No.1 12.

Row storage part 5 is used for the form of view data from input with transforming to output usefulness, wherein has the 1st line storage the 6, the 2nd line storage 7 and the traffic pilot (MUX) 9 of use as required.These the 1st, the 2nd line storages 6,7 are respectively the 1024 word line storages that adapt to the XGA of low exploring degree, and are divided into the memory block that can independently control.

Specifically, the composition of the 1st, the 2nd line storage 6,7 is: have the line storage of 2 512 words, as the memory block that can independently control.The 1st line storage 6 is made of the 1st row storage block (line storage A) 6a and the 1st row storage block (line storage B) 6b, and the 2nd line storage 7 is made of the 2nd row storage block (line storage A) 7a and the 2nd row storage block (line storage B) 7b.

This is because when being used for HDTV plate shown in Figure 4, parallel input odd number of images data DT_O and even image data DT_E, the 1st line storage 6 of (1,1M) if master controller, then the 1st row storage block 6a becomes and is used for odd number, and the 1st row storage block 6b becomes and is used for even number.The 2nd storer 7 is also identical.The 1st storer 6 of slave controller (1,1S) in contrast.

As indicated above, the view data input of row storage part 5 is had from the input of input part 2 with from these two systems of input of input and output portion 4.Utilize the control of control part 3, make as XGA when using, only use input from input part 2, and as HDTV when using, all obtain using from the input of input part 2 with from these two systems of input of input and output portion 4.

Each view data DT that is about to be input to capable storage part 5 is stored in the 1st line storage 6 or the 2nd line storage 7 by the timing of the clock signal clk of input together from left end during allowing signal DE for " height " level showing.In the 1st, the 2nd line storage 6,7 which side view data DT that will input by control part 3 control be stored in.For example, when view data DT is stored in the 1st line storage 6 successively, carry out reading view data from the opposing party's the 2nd line storage 7.Like this, between the 1st and the 2nd line storage 6 and 7, each is exercised view data DT and deposits and read not only by turns with view data DT but also carry out.

From row storage part 5 when reading view data hierarchy number can select 1 system or many body system as required.Here, be: when using use, read by 2 systems as XGA as the situation shown in the example; When using use, read by 1 system as HDTV.

As indicated above, the input part 2 of control part 3 control display controller devices 1, input and output portion 4 and the running separately of row storage part 5.Control part 3 uses according to this display controller device 1 is used with use or as HDTV as XGA, makes the running of each one adapt to the exploring degree.Exploring degree specification signal with the outside input carries out the setting of this exploring degree, and when for example exploring degree specification signal was " height " level, it was HDTV that control part 3 is judged into purposes.

Specifically, control part 3 makes each row of view data rotate not only but also carry out the deposit operation and the read operation of the view data of the 1st and the 2nd line storage 6 and 7.And display controller device 1 operates with the 1st pattern and the 2nd pattern according to the control of control part 3.

In the 1st pattern, do not carry out transmitting, only will be stored in the 1st or the 2nd line storage 6,7 from 1 view data of going share of input part 2 inputs by the view data of data input and output portion 4.

In the 2nd pattern, bear the view data that the view data of the respective picture of driving sends here by input and output portion 4 with other display controller device 1 view data of 1 row share of 1 system of the regulation that will divide from input part 2 input and by 2 systems and be stored in the described the 1st or the 2nd line storage 6,7, and the view data beyond the respective picture is sent to the regulation display controller device 1 of bearing driving by data input and output portion 4.

Control part 3 also judges with regard to this display controller device 1 it is to use as master controller (Master), still as slave controller (Slaver) under the situation that HDTV uses.During the use used as HDTV, owing to use in 1, two of two display controller device any to become master controller, another becomes slave controller as shown in Figure 4.The control part 3 of 3 pairs of slave controllers of control part of master controller sends the running control signal that bus direction between control master controllers and the slave controller is switched usefulness, promptly controls the running control signal that the function of the input and output portion 4 of slave controller is used.The control part 3 of slave controller switches the function of input and output portion 4 according to the running control signal that master controller sends.Main specification signal with the outside input carries out this principal and subordinate's setting, and when for example main specification signal was " height " level, it was master controller that control part 3 is judged as this display controller device.

Then, with Fig. 2～Fig. 5 low exploring degree display and the high-resolution display that loads this display controller device 1 is described.Here, for easy, to description and the explanation in the scan line drive circuit omission accompanying drawing.

As shown in Figure 2, supply with view data DT from the tuner 50 of outside, DVD device 51, VTR device 52 etc. with the form of vision signals such as NTSC, and after video source 53 was transformed into view data DT, clock signal clk and synchronizing signal SYCN, the driving circuit portion of display board 55 was supplied with in the demonstration through comprising one or more display controller devices 1 with control device 54.Display board 55 has the composition identical with above-mentioned display board shown in Figure 6 211.Example is equipped with the situation of HTV plate as the high-resolution display of display board 55 among Fig. 2, thereby shows that the display controller device 1 with control device 54 is 2.

Fig. 3 is with the low exploring degree display of XGA plate 16 as display board 55, has HGA plate 16,14,1 above-mentioned display controller device 1 of signal-line driving circuit.Signal-line driving circuit 14 drives many signal line (not shown) of XGA plate 16, has the source circuit plate 15L, the 15R that separate separately in left picture and the right picture.Source circuit plate 15L goes up and forms 4 source electrode driver SD1～SD4, and source circuit plate 15R goes up and forms 4 source electrode driver SD5～SD8.

When using use, show that control element 1 with the 1st mode operating, does not use the input and output portion 4 of display controller device 1, only will allow signal DE and clock signal clk send to capable storage part 5 from view data DT, the demonstration of outside through input part 2 as XGA.Here, reading view data from row storage part 5 is 2 systems, exports the view data of left picture 17L and the view data of right picture 17R simultaneously.

The sequential chart of the low exploring degree display of employing XGA plate 16 is identical with above-mentioned Fig. 8.Will through view data (being IN_DT among the figure) DT1, the DT2 of input part 2 input, DT3 ..., DT1024 timing by clock signal clk during show allowing signal DE for " height " level begins to be stored in successively the 1st line storage 6 (from its left end) from view data DT1.But in the present embodiment, the 1st, the 2nd line storage 6,7 constitutes by a pair of storage block, thereby specifically, deposits: from the left end of the 1st storage block 6a to right-hand member, then from the left end of the 1st storage block 6b to right-hand member.

When view data is stored in the 1st line storage 6, with the view data DT1 of picture left end and the view data DT513 of picture central authorities is starting point, by left end simultaneously view data (the figure for O_DT) DT1, the DT2 before the 2nd line storage 7 is read 1 row of having deposited, DT3 ..., DT1024.As indicated above, the 1st, the 2nd line storage 6,7 constitutes by a pair of storage block, thereby specifically, reads simultaneously from the 2nd row storage block 7a and the 2nd row storage block 7b respectively.

The view data DT1 of picture left end is the 1st view data that should be written to left picture 17L, reads this data from the 2nd row storage block 7a.With the view data DT1, the DT2 that read from the 2nd row storage block 7a successively, DT3 ..., DT512 begins to be input to successively 4 source electrode driver SD1～SD4 that drive left picture 17L from the source electrode driver SD1 of left end.On the other hand, the view data DT513 of picture central authorities is the 1st view data that should be written to right picture 17R, reads this data from the 2nd row storage block 7b.With the view data DT513, the DT514 that read from the 2nd row storage block 7b successively, DT515 ..., DT1024 begins to be input to successively 4 source electrode driver SD5～SD8 that drive right picture 17R from the source electrode driver SD5 of left end.At this moment output frequency is half of incoming frequency.

With view data DT1, the DT2 of follow-up 1 row share, DT3 ..., DT1024 is stored in the 2nd line storage 7 successively, specifically, therefore is stored in the 2nd storage block 7a, 7b, its step with above-mentioned to the 1st storage block 6a, 6b to deposit step identical.Meanwhile, by 2 systems from the 1st storer 6 read view data DT1, DT2, DT3 ..., DT512 and view data DT513, DT514, DT515 ..., DT1024, its step is identical with above-mentioned step of reading from the 2nd storage block 7a, 7b.

Every like this, successively row carries out writing and reading of view data in turn at the 1st line storage 6 and the 2nd line storage 7.

On the other hand, Fig. 4 is with the HDTV plate 26 high-resolution display as the display board 55 of Fig. 2, has HDTV plate 26, signal- line driving circuit 24 and 2 and constitute the display controller device 1,1 that shows with control device.

Signal-line driving circuit 24 drives many signal line (not shown) of HDTV plate 26, has the source circuit plate 25L, the 25R that separate separately in left picture and the right picture.Source circuit plate 25L goes up and forms 7 source electrode driver SD1～SD7, and source circuit plate 25R goes up and forms 7 source electrode driver SD8～SD14.

When being used for the high-resolution display, load 2 described display controller devices 1, each display controller device 1 all operates with the 2nd pattern.In 2 display controller devices 1,1, one is master controller, and another is a slave controller.Here the display controller device 1 of left end is master controller 1M, and the display controller device 1 of right-hand member is slave controller 1S.Allow signal DE and clock signal clk from outside input odd number of images data DT_O, demonstration among the master controller 1M, allow signal DE and clock signal clk from outside input even image data DT_E, demonstration among the slave controller 1S.

And, form the BDB Bi-directional Data Bus 20 of the input and output portion 4,4 that is connected both sides between these master controllers 1M and the slave controller 1S, utilize the bus direction switching of the running control signal that master controller 1M supplies with slave controller 1S (switching the signal of function of the input and output portion 4 of slave controller 1S) this data bus 20 of control.Under the situation of HDTV, the view data of each row storage part 5 is read 1 system that is among master controller 1M and the slave controller 1S.

Fig. 5 is the sequential chart that adopts the high-resolution display of HDTV plate 26.Among the HDTV, with odd number of images data (IN_DT_O among the figure) DT1, DT3, DT5 ..., DT1919 and even image data (IN_DT_E among the figure) DT2, DT4, DT6 ..., DT1920 allows signal DE and clock signal clk to import simultaneously with demonstration.Wherein, odd number of images data DT1, DT3, DT5 ..., DT1919 allows signal DE and clock signal clk to be input to the input part 2 of master controller 1M with demonstration, even image data DT2, DT4, DT6 ..., DT1920 allows signal DE and clock signal clk to be input to the input part 2 of slave controller 1S with demonstration.

Among the master controller 1M, under the control of control part 3 (not shown), with the odd number of images data DT1 suitable, DT3, DT5 of the odd number of images data of 1 row share of input with left picture 27L (first half) ..., DT959 show to allow signal DE for begin to be stored in the odd number storer of the 1st line storage 6 of capable storage part 5 during " height " level successively from left end by the timing of the clock signal clk of input together, promptly the 1st goes storage block 6a.

On the other hand, among the slave controller 1S, under the control of storage part 3, with the input 1 the row share the even image data in, be equivalent to left picture 27L (first half) even image data DT2, DT4, DT6 ..., DT960 is together with the clock signal clk of input and show to allow signal DE to be sent to master controller 1M from input and output portion 4 by data bus 20, does not leave the capable storage part 5 of itself in.During this, slave controller 1S does not carry out the deposit data to the capable storage part 5 of itself.

Among the master controller 1M, like this with DT1, DT3, DT5, when the odd number of images data till the DT959 are stored in the 1st row storage block 6a successively from left end, to be equivalent to DT2 by what slave controller 1S sent like this with the left picture 27L (first half) of delegation, DT4, DT6, even image data till the DT960, allow signal DE and clock signal clk with the demonstration that sends together, show to allow signal DE be " height " level during, begin to be stored in the even number storer of the 1st line storage 6 of capable storage part 5, i.e. the 1st row storage block 6b successively from left end by the timing of clock signal clk.

Like this, the view data (odd number of images data and even image data) of left picture 27L that will be equivalent to the view data of 1 row share is stored in the 1st line storage 6 of master controller 1M, then switches both sides' processing between master controller 1M and slave controller 1S according to the running control signal of control part 3 outputs of master controller 1M.Then master controller 1M transmits the odd number of images data of importing by input part 2 to slave controller 1S next time.

Promptly, in the odd number of images data of the 1 row share that the control part 3 of master controller 1M will be imported, be equivalent to right picture 27R (latter half) odd number of images data DT961, DT963, DT965 ..., DT1919 is together with the clock signal clk of input and show to allow signal DE to be sent to slave controller 1S from input and output portion 4 by data bus 20, does not leave the capable storage part 5 of itself in.During this, master controller 1M does not carry out the deposit data to the capable storage part 5 of itself.

Among the slave controller 1S, with the 1st row storage block 6a to master controller 1M deposit even image data DT962 that the odd number of images data will import by the input part 2 of itself in the same manner, DT964, DT966 ..., DT1920 is stored in the even number storer, i.e. the 1st row storage block 6a, simultaneously the odd number of images data DT961 that also master controller 1M is sent here by input and output portion 4, DT963, DT965 ..., DT1919 is stored in the odd number storer, it is identical that i.e. the 1st row storage block 6b, its mode and the 1st capable storage block 6b to master controller 1M deposit the even image data.

Like this, between master controller 1M and slave controller 1S, one side exchanges both sides' input data, and one side is finished the depositing of view data of 1 row share.

And, between this storage period, be starting point also simultaneously with the view data DT1 of picture left end and the view data DT961 of picture central authorities, from each the 2nd storer 7 of master controller 1M and slave controller 1S simultaneously by left end begin to read successively view data (O_DT_L the figure, O_DT_R) DT1, DT2 before 1 row of having deposited, DT3 ..., DT1920.In the present embodiment, the the 1st and the 2nd storer 6 of master controller 1M and slave controller 1S and 7 constitutes by a pair of capable storage block, so specifically, after reading view data since the 2nd row storage block 7a and the 2nd row storage block 7b by left end respectively, put up with it by traffic pilot 9 by 1 system and read.

The view data DT1 of the picture left end that master controller 1M reads at first is the 1st view data that should be written to left picture 27L.In the reading of view data, after reading from the 2nd row storage block 7a that deposits the odd number of images data and the 2nd row storage block 7b that deposits the even image data, by alternately output of multi-channel converter 9.To be with the view data DT1 of picture left end the first view data DT1 that reads successively, DT2, DT3 ..., DT960 begins to be input to successively 7 source electrode driver SD1～SD7 that drive left picture 27L from the source electrode driver SD1 of left end.

On the other hand, the view data DT961 of the slave controller 1S picture central authorities of reading at first is the 1st view data that should be written to right picture 27R.In the reading of view data, after reading from the 2nd row storage block 7a that deposits the even image data and the 2nd row storage block 7b that deposits the odd number of images data, by alternately output of multi-channel converter 9.To be with the view data DT961 of picture central authorities the first view data DT961 that reads successively, DT962, DT963 ..., DT1920 begins to be input to successively 7 source electrode driver SD8～SD14 that drive right picture 27R from the source electrode driver SD8 of left end.

At this moment output frequency is identical with incoming frequency, thereby finish with view data DT1, DT2, the DT3 of 1 row share ..., when DT1920 is stored in each the 1st line storage 6 of master controller 1M and slave controller 1S successively, each the 2nd line storage 7 of master controller 1M and slave controller 1S becomes the free time.With view data DT1, the DT2 of follow-up 1 row share, DT3 ..., DT1920 is stored in the 2nd line storages 7,7 of these free time, its mode is with above-mentioned that the 1st line storage 6,6 is deposited view data is identical.

Meanwhile, by picture left end and the beginning of picture central authorities, from each the 1st line storage 6,6 of master controller 1M and slave controller 1S by 2 systems read view data DT1, DT2, DT3 ..., DT960 and view data DT961, DT962, DT963 ..., DT1920, its mode is with above-mentioned to read view data from the 2nd storer 7,7 identical.

Like this, identical during with XGA, among master controller 1M and the slave controller 1S, to utilize separately the every successively row of control part 3 to make and write and read by turns in the 1st line storage 6,6 and the 2nd line storage 7,7 one sides, one side is carried out data conversion and is handled.

In sum, here with showing that the view data of that it(?) will per 2 pixels with control device import by 2 systems is transformed into the view data of each picture that is divided into 2 on the picture horizontal direction respectively and outputs to by 2 systems in the demonstration of high-resolution display of display driver portion, to interconnect and form 2 identical display controller devices 1 by data bus, 1 as the demonstration control device, make by the view data of 2 systems inputs one by one system be input to these display controller devices 1,1, and the respective picture view data in addition that each display controller device 1 will be born driving is sent to another display controller device 1 of bearing driving by data bus, and the view data of the respective picture that the view data of respective picture is sent here by data bus with another display controller device 1 is stored in built-in line storage 5, and be transformed into output image data.

By being taken as this composition, the memory capacity of each display controller device 1 built-in line storage can be with 1 display controller device and constitutes 1/2 of required memory capacity when showing with control device, thereby for example the demonstration of HDTV (1920 * 1080) usefulness is used in the control device, memory capacity as built-in line storage, though the demonstration that needs XGA (1024 * 768) usefulness is with roughly 2 times of control device, be used as the composition that demonstration that low exploring degree XGA uses is worked with control device but be taken as in advance, and make 2 this control device are used as the demonstration control device that high-resolution HDTV uses, just can tackle the memory capacity of the capable storage part 5 of display controller device 1.

Promptly, so just can shared formation hang down the display controller device and the demonstration that constitute high-resolution display controller device with control device of the demonstration of exploring degree with control device, thereby it is unified to seek display controller device (device) with the state that obtains cost advantage, and then can realize that display device at a low price.

Here, as showing that the view data of every N (N is equal to or greater than 2 integer) pixel being imported by the N system with control device is transformed into view data that is divided into each individual picture of N on the picture horizontal direction and the driving method that outputs to the display device of display driver portion by N * k (k is the integer that equals greater than 1) respectively, example N is 2, k is 1 situation, but also can be its outer example.

When using control device with 1 demonstration of a plurality of display controller devices 1 formation, in each display controller device 1, together with view data DT, input clock signal CLK and demonstration allow display control signals such as signal DE together, thereby which picture is each display controller device identification respective picture separately be, only the view data of respective picture is stored in the capable storage part 5 of itself, the view data of non-respective picture then is sent to other display controller device 1, thereby should be able to distinguish drive.Yet, in fact because the manufacture deviation of the relation of data transfer path length and each display controller device might produce defective.

Otherwise, in the present embodiment, make on the structure: when control device is used in the demonstration of formation high-resolution display, 1 master controller 1M in 2 display controller devices 1,1, control the driving of another slave controller 1S, thereby the defective that can avoid bringing the manufacture deviation of display controller device of each circuit of formation of the relation of data transfer path length to cause.

Again, when using control device with 1 demonstration of a plurality of display controller devices 1 formation, in each display controller device 1, together with view data DT, input clock signal CLK and show to allow display control signal such as signal DE together, thereby the demonstration that also can be taken as each display controller device 1 usefulness direct input itself on the structure is stored in capable storage part 5 with control signal with the view data that sends.Yet, in fact as indicated above because the manufacture deviation of the relation of data transfer path length and each display controller device 1 may produce defective when depositing the view data that sends with the display control signal of directly input.

Otherwise, in the present embodiment, make on the structure: when view data DT is sent to another display controller device 1, also transmit together and comprise the display control signal of the clock signal clk of input together, thereby the defective that can avoid bringing the manufacture deviation of display controller device of each circuit of formation of the relation of data transfer path length to cause.

Again, the total line number that view data is used is many, thus by be taken as like this can two-way transmission data BDB Bi-directional Data Bus, can make the small of control circuit itself.Yet when being taken as BDB Bi-directional Data Bus, the switching of bus direction needs the time, even the bus direction is switched in the pixel of for example numbering according to the rules decision, also may produce overtime.

Therefore, in the present embodiment, make on the structure shown in the sequential chart of Fig. 5, the odd number of images data of regularly directly importing at identical clock to the 1st row storage block 6a deposit and as the even image data of the view data that sends to the depositing of the 1st row storage block 6b, postpone several time clock but preferably make the driving timing of depositing that depositing of the view data that sends started regularly with respect to the view data of direct input on the structure.Like this, can guarantee the switching time of BDB Bi-directional Data Bus, can avoid bringing the bus direction to switch the defective that required delay causes.
