BACKGROUND OF THE INVENTION 1.

2. Description of the Related Art FIG. 12 shows a structure of a pixel portion of a conventional active matrix liquid crystal display device. In FIG. 12, 1
1 is a signal line (Vs), 12 is a scanning line (Vg), 13 is a thin film transistor (TF) located at the intersection of the signal line and the scanning line.
T), 14 are pixel electrodes (Vp) connected to the TFT, 1
Reference numeral 5 is a liquid crystal capacitance equivalent to a liquid crystal element, 16 is a storage capacitance that assists the liquid crystal capacitance, and 17 is a counter electrode (VCOM) connected to the liquid crystal capacitance. In many cases, the storage capacitor 16 is commonly connected to the counter electrode 17 in parallel with the liquid crystal capacitor 15 or connected to the scanning line in the preceding stage or the succeeding stage. FIG. 12 shows the former example.

FIG. 13 shows an example of drive waveforms of a liquid crystal display device having a pixel structure as shown in FIG. As shown in Figure 13,
Once in the frame period, the voltage Vg of the scanning line becomes high potential and the TFT is turned on. The voltage Vs of the signal line at this time is held in the liquid crystal capacitance and the storage capacitance, and the voltage Vp of the pixel electrode
Becomes equal to the voltage Vs of the signal line. Further, when the voltage Vg of the scanning line becomes low and the TFT is turned off, the voltage Vp of the pixel electrode is slightly decreased due to the punch-through voltage due to the parasitic capacitance of the TFT. As a result, the voltage Vp of the pixel electrode and the counter voltage VCOM which have reached are reached. The potential difference Vlc between the voltage and the voltage becomes the voltage applied to the liquid crystal.

In the next frame period, the polarities of the signal line voltage Vs and the counter voltage VCOM are inverted with respect to the previous frame, and so-called frame AC drive is performed. When displaying the same gradation, the potential difference between the pixel voltage Vp and the counter voltage VCOM in each frame, that is, the liquid crystal applied voltage Vl
Although the sizes of c are equal, the sign of Vlc is inverted for each frame. Actually, in order to reduce flicker caused by a slight difference between positive and negative liquid crystal applied voltages, the signal line voltage and the counter voltage are inverted every horizontal scanning period within one frame period, and the liquid crystal is applied to adjacent scanning lines. The polarities of the voltages are different. In this way, the driving method for inverting the polarity of the liquid crystal for each line is called line inversion driving, and the driving method for inverting the counter voltage for each horizontal scanning period to perform the line inversion driving is called counter inversion driving.

There is a drive method called independent capacitive coupling drive (hereinafter referred to as independent CC drive) as opposed to the counter inversion drive.
This driving method is disclosed in, for example, Japanese Patent Laid-Open No. 2001-83943. FIG. 14 shows an example of a pixel structure in independent CC drive. 14, those having the same functions as those in FIG. 12 are designated by the same reference numerals, and the description thereof will be omitted. Reference numeral 31 is a storage capacitance line (Ve). In FIG. 14, the storage capacitor 16 is the counter electrode 1.
It is not connected to 7, but connected to the storage capacitance line 31. The storage capacitance line 31 is driven independently of the scanning line 12 and the counter electrode 17.

FIG. 15 shows a drive waveform of the independent CC drive.
In FIG. 15, the opposite voltage VCOM is a constant voltage, and the pixel voltage Vp is changed through the storage capacitor by periodically changing the voltage Ve (hereinafter referred to as a compensation voltage) of the storage capacitor line for each frame by two values. Frame AC drive is used.

FIG. 16 shows a driving waveform of the compensation voltage Ve when the scanning lines Vg1 to Vg4 are sequentially selected. As shown in FIG. 16, the direction of polarity reversal of the compensation voltage Ve changes line by line, and line inversion driving as shown in FIG. 17 can be performed.

As described above, since the counter voltage can be made constant in the independent CC drive, the power consumption can be reduced as compared with the counter inversion drive. Further, in the independent CC drive, although the counter voltage is constant, the AC drive of the liquid crystal is performed through the storage capacitor, so that the voltage amplitude of the signal line is limited to the voltage range of one polarity of the liquid crystal, and the charge and discharge of the signal line capacitance is performed. Power consumption can be reduced. Further, the independent CC drive has an advantage that the voltage amplitude of the scanning line can be made smaller than that of the conventional CC drive in which the storage capacitance is arranged on the scanning line at the preceding stage or the succeeding stage.

[0009]

However, the independent C
The C drive has the following problems. That is, in the independent CC drive, the scanning line and the storage capacitance line are driven independently,
When the drive circuit for the storage capacitance line and the drive circuit for the scanning line are built in the vertical drive circuit, the number of outputs of the vertical drive circuit is required to be twice the number of the scan lines. This leads to an increase in the area of the vertical drive circuit. Further, when the vertical drive circuit is realized by a semiconductor integrated circuit (LSI), the chip area of the LSI increases substantially in proportion to the number of outputs, which causes a cost increase.

In recent liquid crystal display devices for mobile phones, the left and right picture frames of the liquid crystal module are minimized, and the liquid crystal screen is arranged at the center of the mobile phone set to improve the design. ing. An example thereof is shown in FIG. 181 is a mobile phone set main body, 182 is a liquid crystal screen, and 183 is a center line of the set main body 182. By designing the center line of the liquid crystal screen 182 to match the center line 183 of the set, the design is improved. In order to realize this, there is a method in which the liquid crystal module has a configuration as shown in FIG. In FIG.
191, a liquid crystal module, 192, an effective display area, 19
3 is a horizontal drive circuit, and 194 is a vertical drive circuit. Figure 1
In FIG. 9, the vertical drive circuit 194 is arranged along the same side as the horizontal drive circuit 193, which is a so-called frame-free three-side configuration. The independent CC drive has a problem that the chip size is large and it is difficult to adopt a three-side free configuration because the number of outputs of the vertical drive circuit is large. Although the drive circuits for both the scanning lines and the storage capacitance lines are collectively referred to as vertical drive circuits here, the drive circuits for the storage capacitance lines may be configured separately from the scan line drive circuits or built in the horizontal drive circuit. A configuration is also conceivable, and in this case as well, a similar problem occurs with respect to the number of outputs.

[0020]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below.

(Embodiment 1) FIG. 1 shows a first embodiment of the present invention. In FIG. 1, 71 is a signal line (Vs),
72 is a scanning line (Vg), 73 is a thin film transistor (TFT) located at the intersection of the signal line and the scanning line, 74 is a pixel electrode connected to the TFT, 75 is a liquid crystal capacitance equivalent to a liquid crystal element, and 76 is a liquid crystal capacitance. A storage capacitor to assist, 77 is a counter electrode (VCOM) connected to the liquid crystal capacitor, and 78 is a storage capacitor line (Ve). The storage capacitors of the pixels belonging to the odd-numbered scanning lines Vg1 and Vg3 are connected to the common storage capacitor line Ve1. The storage capacitors of the pixels belonging to the even-numbered scanning lines Vg2 and Vg4 are connected to the common storage capacitor line Ve2. Therefore, the number of storage capacitance lines is halved compared to the case of the conventional configuration of FIG.

FIG. 2 shows an example of drive waveforms in the case of normal drive in the configuration of FIG. The polarity of the storage capacitance line Ve1 is inverted after the scanning lines Vg1 and Vg3 are selected.
The storage capacitor line Ve2 has a polarity inversion after the scanning lines Vg2 and Vg4 are selected, and has a phase opposite to that of Ve1. As a result, the line inversion drive shown in FIG. 17 can be realized. However, in the scanning lines Vg1 and Vg3, the storage capacitance line Ve
The holding time of the pixel voltage from when the polarity of 1 is inverted to when the scanning line is selected in the next frame is different by twice the horizontal scanning period. The scanning lines Vg2 and Vg4 are also different. In such a case, since the time averages of the pixel voltages on the two scanning lines are different, the image quality is deteriorated, such as a difference in brightness even at the same gradation.

FIG. 3 shows a method for reducing the above-mentioned image quality deterioration. In FIG. 3, the selection order of the scanning lines is devised so that the scanning lines belonging to the pixels having the common storage capacitance line are continuously scanned. That is, the scanning line Vg3 is selected immediately after the scanning line Vg1 is selected, and the scanning line Vg4 is selected immediately after the scanning line Vg2 is selected. Even in this case, the holding time of the pixel voltage is different only in one horizontal scanning period, but if one horizontal scanning period is sufficiently smaller than one frame period, no difference in luminance will occur. In fact, the scanning lines in liquid crystal panels used in mobile phones etc. are 200 to 3
There are about 00 and it is 1 if the vertical blanking period is considered.
Since the frame period is 200 to 300 times or more as long as the horizontal scanning period, it is considered that there is almost no difference in luminance even if the holding time of the pixel voltage is different for one horizontal scanning period.
In addition, in the first embodiment, the selection order of the scanning lines in which the storage capacitance lines are made common is Vg1 → Vg3, but the order may be reversed.

In FIG. 3, four scanning lines are used as a unit and the selection order of the scanning lines is Vg1 → Vg3 → Vg2 → Vg4. However, as shown in FIG. 4, the odd scanning lines and the even scanning lines are completely replaced. Alternatively, the odd-numbered scan lines may be first scanned, and then the even-numbered scan lines may be scanned (and vice versa). That is, the interlace scanning is 2: 1. The drive waveform of the storage capacitance line is as shown by Ve1 to Ve4 in FIG. Also in this case, as in FIG. 3, the holding time of the pixel voltage of the scanning lines belonging to the same storage capacitance line is different by one horizontal scanning period. In such interlaced driving, the polarity inversion phases of pixels in adjacent scanning lines are shifted by a half frame period, which brings about an effect that flicker can be reduced.

FIG. 5 shows another method for reducing the image quality deterioration that occurs when the storage capacitor lines are shared as shown in FIG. That is, the pixel voltage holding times are made equal by alternating the scanning line selection order for each frame period. In FIG. 5, in an odd frame, Vg1 → Vg
3, and Vg3 → Vg1 in even frames. By performing the scanning in this manner, the sum of the holding times of the pixel voltages becomes equal in the two frame periods, so that no luminance difference occurs. The same applies to the method of selecting Vg2 and Vg4.

In the first embodiment, the case where the two storage capacitance lines of the odd lines or the even lines are shared is described, but if there is no problem in the image quality,
More storage capacity lines may be shared.

(Embodiment 2) FIG. 6 shows a second embodiment of the present invention. 6, those having the same functions as those in FIG. 1 are designated by the same reference numerals, and the description thereof will be omitted. Reference numerals 121 and 122 denote storage capacitance lines (Ve). In FIG. 6, the configuration of the commonly connected storage capacitance line Ve is different from that in FIG. That is, for the signal line Vs1, the storage capacitors belonging to the four scanning lines Vg1 to Vg4 are connected to the common storage capacitor line Ve1. For the signal line Vs2, four scanning lines Vg1 to Vg
The storage capacitors belonging to No. 4 are connected to the common storage capacitor line Ve2. In other words, the adjacent signal lines Vs1 and Vs
At s2, storage capacitors are connected to different storage capacitor lines. Note that the signal lines Vs3, Vs4, and Vs further adjacent to each other
5, Vs6 ... Are not shown, but these storage capacitance lines are similar to the signal lines Vs1 and Vs2.
1, Ve2, Ve1, Ve2 ... With such a configuration, the number of storage capacitance lines is halved as compared with FIG. In addition, the storage capacitance line Ve1
It is possible to perform column inversion drive as shown in FIG. 7 by driving and Ve2 in opposite phases. In general, in the column inversion drive, the polarity of the signal line voltage can be made the same for one frame period, so that there is an effect that the charge / discharge power of the signal line capacitance can be reduced. As the drive waveform, as shown in FIG. 8, a drive waveform in which the scanning capacitor lines Vg1 to Vg4 are selected and then the polarities of the storage capacitor lines Ve1 and Ve2 are inverted can be considered. However, in the method of FIG. 8, for example, in the scanning lines Vg1 and Vg4, the holding time of the pixel voltage differs by three times the horizontal scanning period, which may cause a large luminance difference. Therefore, as shown in FIG. 9, for example, by alternating the selection order of the scanning lines Vg1 to Vg4 using four frame periods, it is possible to equalize the holding time of the pixel voltage in four frames.

In the second embodiment, the case where the storage capacitance lines of four pixels are shared by the same signal line has been described. However, if there is no particular problem with the image quality, more storage capacitance lines can be used. You may make it common. Further, although the adjacent signal lines are connected to different storage capacitance lines, they may be connected to the same storage capacitance line in units of RGB, for example.

(Embodiment 3) FIG. 10 shows a third embodiment of the present invention. In FIG. 10, those having the same functions as those in FIG. Reference numerals 161 and 162 denote storage capacitance lines (Ve). In FIG. 10, the configuration of the commonly connected storage capacitance lines is different from that in FIGS. 1 and 6. That is, for the signal line Vs1, the scanning lines Vg1 and Vg3
The storage capacitors of the pixels belonging to the above are commonly connected to the storage capacitor line Ve1, and the storage capacitors of the pixels belonging to the scanning lines Vg2 and Vg4 are commonly connected to the storage capacitor line Ve2. Regarding the signal line Vs2, the connection relationship between the signal line Vs1 and the storage capacitance line is reversed. In other words, the storage capacitors in the pixel area of horizontal 2 dots × vertical 4 dots are connected to the storage capacitor lines Ve1 and Ve2 like a checkered pattern. With such a configuration, the number of storage capacitor lines is halved compared to the conventional configuration shown in FIG. Further, by driving the storage capacitance lines Ve1 and Ve2 in opposite phases,
It is possible to perform dot inversion drive as described above. Generally, the dot inversion drive has an advantage that a high-quality image with less flicker and crosstalk can be provided as compared with the line inversion drive and the column inversion drive. As the drive waveform, as in the second embodiment, as shown in FIG.
After selecting 1 to Vg4, the storage capacitance lines Ve1 and Ve are selected.
Although a drive waveform that inverts the polarity of 2 is conceivable, it is feared that a large luminance difference may occur between the scanning lines Vg1 and Vg4, and therefore, as shown in FIG. By alternating the selection order of, the holding time of the pixel voltage in the four frames can be made equal.

In the third embodiment, the case where the storage capacitance lines of two pixels are shared by the same signal line has been described. However, if there is no particular problem with the image quality, more storage capacitance lines can be used. You may make it common.

As described above, the number of outputs of the vertical drive circuit can be reduced by sharing the storage capacitance line in the independent CC drive. If the number of outputs of the vertical drive circuit can be reduced,
As shown in FIG. 19, it is possible to adopt a structure in which the three sides of the frame are free, and as shown in FIG. 18, the liquid crystal screen can be arranged at the center of the set main body. Although the drive circuit of the storage capacitance line is incorporated in the vertical drive circuit 194 in FIG. 18, it may be configured independently of the vertical drive circuit 194 or may be incorporated in the horizontal drive circuit 193.
This embodiment can be applied to either case.

[0032]

According to the embodiments of the present invention, in the independent CC drive capable of lowering the power as compared with the conventional one, by sharing the storage capacitance line in a plurality of pixels, the scale of the drive circuit for the storage capacitance line is increased. Can be reduced, and the number of outputs of the drive circuit for the storage capacitance line can be reduced. If the number of outputs of the storage capacity line drive circuit can be reduced, if the storage capacity line drive circuit is combined with the scanning line drive circuit to form a vertical drive circuit, the vertical drive circuit chip size can be made smaller and the cost can be reduced. Has the effect that is possible. This has the same effect whether the drive circuit for the storage capacitance line is independent of the drive circuit for the scanning line or incorporated in the horizontal drive circuit.

In addition, a vertical drive circuit is arranged in line with a horizontal drive circuit along one side of the liquid crystal panel, so-called frame 3
This has the effect that a side-free configuration can be easily realized. Furthermore, if a liquid crystal module to which a three-sided frame is applied is installed in a mobile phone, the liquid crystal screen can be placed in the center of the set body, which has the effect of improving the design. This effect can be obtained in the same manner when the drive circuit for the storage capacitance line is configured independently of the drive circuit for the scanning line or when it is built in the horizontal drive circuit.

Further, in the first embodiment of the present invention, since line inversion driving can be performed with a configuration in which the storage capacitor lines are made common, flicker and crosstalk are less than in simple frame inversion driving, and a high quality image is provided. It has the effect of being able to. Further, flicker can be further reduced by performing the interlaced scanning of 2: 1. Further, by alternating the selection order of the scanning lines for each frame, it is possible to reduce the luminance difference due to the difference in the holding time of the pixels belonging to the common storage capacitance line, and it is possible to provide a high-quality image.

Further, in the second embodiment of the present invention, since the column inversion drive can be performed with the configuration in which the storage capacitor lines are made common, flicker and crosstalk are less than in the simple frame inversion drive, and a high quality image is provided. It has the effect of being able to. In the column inversion drive, since the polarity of the signal line voltage is inverted for each frame, there is an effect that the charge / discharge power of the signal line capacitance can be reduced as compared with the line inversion drive. Further, by alternating the selection order of the scanning lines for each frame, it is possible to reduce the luminance difference due to the difference in the holding time of the pixels belonging to the common storage capacitance line, and it is possible to provide a high-quality image.

Further, in the third embodiment of the present invention, since the dot inversion drive can be performed with the configuration in which the storage capacitor lines are shared, flicker and crosstalk are generated as compared with the frame inversion drive, the line inversion drive and the column inversion drive. It has the effect of providing few and high quality images. Further, by alternating the selection order of the scanning lines for each frame, it is possible to reduce the luminance difference due to the difference in the holding time of the pixels belonging to the common storage capacitance line, and it is possible to provide a high-quality image.
