The second aspect of this embodiment * is because the control signal is switched during each scanning period. As shown in the figure, no matter where the scanning line is, When the control line is at the L level, there is no difference in the time relative to the writing of the portrait data. Therefore, there is also no difference in the effective electric energy between the pixel P (1,] ·) and the pixel P (m, j). , And no brightness distortion is generated in the scan display of the same color.

Therefore, the problem of lowering the holding rate can also be solved. In the second aspect of the foregoing one embodiment, no matter during each scanning line period Switching the control signal or any position of the scanning line can also eliminate the difference between the time when the control signal is at the L level and the time when the image data is written.

However, in the common reverse driving, the polarities of the daytime image signals at the same time must be the same. Therefore, the capacity of the signal line and the counter electrode is combined to change the potential of the counter electrode. In this case This is because it is caused by a decrease in contrast or an increase in crosstalk.

Here, the cancel signal may be formed with the opposite polarity to the image signal by the sum of the control signals of the control lines CA and C B. Therefore, the overlap of the cancel signal is not limited to the above-mentioned form, and it may be overlapped with the control signal at the level, or with any of the control signals. According to the fifth aspect of the above-mentioned one embodiment, the cancellation signal prevents the potential of the counter electrode from changing.

For example, as shown in Figure 1, when the number of signal lines Dj is equal to the number of added control lines CA and CB, and the widths of these signal lines and control lines are all the same, the average value of the image signals is calculated from the above-mentioned integrated value. f is twice the size of the average value, and a voltage opposite to the polarity of the image signal is superimposed on the control signal, and the level conversion of the overlapped signal is performed. However, in this case, the size of the cancellation signal is set to twice the average value, because the number of control lines for overlapping cancellation signals is formed to be 1/2 of the number of signal lines. With regard to such a structure, as shown in FIG. 15 ′, during the display of one item i, the integration circuit 10 integrates the image signal of the next i + 1th line (in the figure, the period of integration #).

Due to this, the level conversion circuit 1 2 converts the control signal to a level based on the integrated value, and outputs the level converted after the effective display period of the first line ends. Control signal (~ CB / output # in the figure). Then continue this situation and start the display of the i + 1th line. In this way, according to this situation, the cancellation signal is calculated at any time because the level of the image signal is taken into account, so It can eliminate the effect of the image signal level, and it can be formed to completely remove the change in the potential of the counter electrode. ≪ Other implementations > Seal of the Consumers ’Cooperative of the Central Government Bureau of the Ministry of Economic Affairs (please read the precautions on the back first) fill in (Page) Hereinafter, other embodiments of the present invention will be described with reference to the drawings.

For this reason, during a horizontal scanning period, only the pixels (P (l, l), P (1,4), P (1,4), ...:, P (1, j) located on the control line CA side of the first row are included. ), P (1, j + 3) ...), both the switching element TD and the switching element CA are turned ON. The image data supplied from the signal line to these pixels is written. Here, the image data is supplied in accordance with the image signal corresponding to the data. However, in this case, it is shown as Di and D3 in the figure. The same polarity is used in 1 horizontal scanning period, and 毎 1 The inverted polarity during the horizontal scan provides the image signal. In addition, the same applies to image signals supplied through signal lines D5, D7, ... other than the illustration. "For this reason, first, the above-mentioned first line displays image data during operation. As shown in the figure, the image signal is supplied with + polarity, and the pixels formed in the 1st row and the jth column and the 1st row and the j + 3th column are written into the portrait data with the + polarity.

In addition, the control signals of the control lines C A and C B maintain the above-mentioned state, and the switching element T CA element is still ON state * the switching element T CB is still 0 F F state. Because of this, only the pixels (P (2,1), P (2,4), P (2, j)), P (2, j + 3) .......), both the switching element T d and the switching element T CA are turned on, and the image data is written in these pixels. Here, the polarity of the image signal is changed as described above. Reversed, so this paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm) -26-413 SO 09? A7 B7 V. Description of the invention After the polarity of the opposite polarity is written to 0, the control signal of the control line c A is set to the high level, and the control signal of the control line C B is set to the L level. * The gate signal of G 4... Is the Η level (not shown in the figure), and the image data is written to the pixels of each row. For this reason, it is distinguished by 1 scan from time ti to t2 During this period, the image data is written to the pixels P (i 'j) and P (i, j + 3) (i = 1, 2' ......, m; j = 1, 5 ..... ... n- 3). Figure 21 (a) is a polar pattern with a portrait shadow of 0 This means that the pixels of the image data are written in. However, the parts with no polarity of 0 in the figure indicate that the pixels of the image data have been written in the scanning area before time t1. Cooperative Du Printing (please read the precautions on the back before filling this page) Secondly, since the 20th figure becomes time t2, the next display of the scanning area is started, and the control signal of the control line CA is set to the L level. The control signal of the control line CB is set to Η level, the above-mentioned switching element D is in the FF state, and the switching element T CB is in the ON state. That is, it replaces the pixel P (i, j) and P (i, j + 3), and set the pixels P (i, j + 1) and P (i, j + 2) to a state where image data can be written. Then, as above, first scan The gate signal of the sight line Gi is set to the Η level | it only lies in the pixels (P (1, 2), P (1, 3)) located on the control line CB side of the first row... P (1 + j + 1), P (1, j + 2), ...), the switching element T d and the switching element T CB are in the 0 N state, and the picture is written with a + polarity in these pixels This paper size applies to China's national standard (CNS > A4 size (210X297mm) -27-Printed by the Shelling Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs 439009 A7 B7 V.

In this figure, Figure 2B is also the pixel of the image data written with the polarity of the image signal with the mark ○. In addition, the part of the circle that is not marked with the ◦ mark indicates that the scanning area before time 2 is the time ~ The pixels of the image data written in the above-mentioned scanning area at t2; these pixels are equivalent to the pixels in which the circle of the 21A is marked with the 0 mark in the polarity of the image signal. As shown by the circles, the polarity reversal in this state is similar to the 1Η reversal of the polarity reversal during each horizontal scanning. After that, the display operation is similarly repeated, and the pixels P (i, j) and P (i, j + 3) or the pixels P (i, j + 1) and (i, j) are selected in each scanning area. +2) Then write the image data.

Description of the invention (% shown in the figure, regardless of the position of the scanning line * When the control signal is at the L level There is no difference between the time and the relative time when the image data is written. Therefore, there is no difference in the effective voltage between the pixel p (1, j) and the pixel: (· m, j), and the scanning display with the same color can also be eliminated. Brightness distortion However, in the case of the above display operation, there is a problem of reducing the retention rate of the image signal at each pixel. Here, as shown in FIG. 26, between the switching elements T ^ and TCB The holding capacity C is set at intervals. In this way, the problem of the decrease in the holding rate can also be solved. The second aspect of the previous embodiment is that the control signal is switched during each scanning period, regardless of the scanning line.

However, there are cases where it is intended to be driven using the control signal generation mode of the first aspect of the other embodiment shown in FIG. 20. In this case, the fundamental problem cannot be solved. Since the difference in the effective voltage between the pixel P (1, j) and the pixel p (m, j) in the first aspect of the other embodiment is eliminated, the difference in the voltage value is also considered to be compensated by an appropriate method.

This figure also has the same representation as the above-mentioned Figures 2 1 and 24. The polarity distribution shown in Figure 30 is closer to the point than the polarity distribution shown in Figures 2 and 24. The expression is reversed * so * the display operation according to this aspect is more difficult to be noticed due to the flicker than the display operation of the first * 2 aspect of the other embodiments described above. However, the polarity of the image signals must be the same at the same time during the common inversion driving. Therefore, due to the combination of the capacity between the signal line and the counter electrode, the potential of the counter electrode is changed.

Any one of the liquid crystal display device formed in the first aspect of the other embodiment of the present invention shown in FIG. 19 and the liquid crystal display device formed in the third aspect of the other embodiment of the present invention shown in FIG. 27 is used. First, at time t8, when the display of a certain display scanning area is started, the control signal of the control line CA is set to the Η level, and the pixels P (1, j) and P on the control line CA side of the first row are set.

The control signal of the bit control line CA overlaps the same cancellation signal as described above. As described above, since the cancellation signal of the counter electrode potential is prevented from overlapping with the control signal, it is possible to suppress a decrease in contrast or an increase in crosstalk. Here, the cancel signal is the sum of the control signals of the control lines CA and C B, and it is also possible to make the image signals to have opposite polarities. Therefore, the overlap of the cancel signal is not limited to the above-mentioned form, and it may be superposed on the control line set to the Η level or the control signal superimposed on one of them.

Therefore, due to the influence of the image signal level, the counter electrode voltage cannot be completely removed. Changes. Here, in the sixth aspect of this other embodiment, the means for superimposing the control signal after specific determination of an appropriate cancellation signal will be described. The 32nd circle is a block diagram showing the configuration of the means for calculating the overlap of the cancellation signal. The figure 1 1 0 in the circle is an integrating circuit. The integral is included in the image signal during a horizontal scanning period, and the integrated value is sequentially output to the sample holding circuit.

Here, the level conversion in the level conversion circuit 1 12 is based on the number and size of the signal line Dj and the control line CA and CB ( Width), etc., so that it can appropriately remove the change in the potential of the counter electrode. For example, as shown in FIG. 19, the number of signal lines Dj is equal to the number of addition control lines CA and CB, and these signal lines When the width of the control line is exactly the same, the average value of the image signal is calculated from the integrated value, which is twice the size of the average value. A voltage of the opposite polarity to the polarity of the image signal is superimposed on the control signal, and the signal is calculated. Level conversion. However, at this time, the size of the cancellation signal is twice the average, which is because the number of control lines overlapping the cancellation signal is formed to 1/2 of the number of signal lines. For such a structure, as shown in FIG. 3 3 As shown in the figure, during the display of an item i, the image signal of the next i + 1 line is integrated by the integration circuit 1 10 (the period of t integration # in the figure). Here, the image signal is supplied to During the effective display period of the 1 horizontal scanning period, if the circle indicates that the integration operation is completed before the end of the 1 horizontal scanning period. Then, when the integration operation is completed, the unitary value obtained at this time is output to the sample holding circuit 1 1 1 and starts outputting to the level conversion circuit 1 1 2. For this reason, the level conversion circuit 1 1 2 is for level conversion control signals based on the integrated value, which starts after the end of the effective display period of the i-th row Output the level-converted control signal (β output | in the figure).

In addition, in this case, because it is related to the switching element TD, the switching element TCA has the same structure as the switching element T CB (meaning that amorphous silicon is formed between the electrodes), so it maintains the voltage dependence of the switching elements TD, TCA, and T CB with a capacity of 150,152.

[Effect of the invention] As explained above, according to the present invention, a control line parallel to the signal line is provided on the liquid crystal panel. The signal ON / OFF of the control line is used to control the second switching element. Therefore, the pixels to be read in the image data can be selected by the signal applied to the control line. Because of this, the effect of reducing the number of signal lines for the number of pixels and avoiding the narrow pitch of the terminal portion of the data driver is obtained. However, because the number of signal lines can be reduced, power consumption can be reduced, and at the same time, the power consumption can be reduced. The effect of preventing an increase in the size of the liquid crystal display device and further achieving a significant cost reduction of the liquid crystal display device is obtained. In particular, since the combination of the predetermined control lines is driven alternately by the driving of each scanning line movement, the relative timings of the driving and the control line driving for all scanning lines are made the same. Because of this, it is possible to prevent the effective voltage of the added signal from forming a different state for each pixel, and to prevent the effect of scanning distortion when forming a scanning display. * Also, because the signals are driven by signals of different polarities, Adjacent identical signals, so you can get a reverse drive that can form a near-point reversal, and you can suppress it (please read the precautions on the back before filling this page) -n · In--n ϋ--n--ϋ.

Furthermore, because the voltage that cancels the voltage according to the signal line is superimposed on the control line *, it is obtained when the common reverse drive is used. It can also suppress the change in the potential of the counter electrode, and can prevent the effect of lowering the contrast or increasing the crosstalk. Furthermore, because the voltage is superimposed based on the average value of the voltage added to the signal line, the signal line signal can be released. The effect of the signal level is completely eliminated, and the change in the potential of the counter electrode is completely eliminated. In addition, because of the ability to prevent the voltage from being added to the pixel voltage when the voltage of the control line is changed, scanning distortion can be improved. It is necessary to add a voltage for compensating the changed voltage, so that it has the effect of suppressing power consumption.
