Among the -1 to 6-M / 2, the first TFT gate G1 and the second TFT gate G2 connected to an arbitrary data line 6-j are two scans assigned to one display line. When the lines 8-i and 8-i + 1 (i = 1 to 2N) are independently connected to form two display pixels and color display is performed, the pixel electrodes 1 (i, j) (i = 1-N,
j = 1 to M), the red pixel electrode R, the green pixel electrode G, and the blue pixel electrode B are sequentially arranged in the lateral direction to form one color pixel.

In the present embodiment, as an example, 1120
× 780 color pixels (Number of pixels: 1120 × 3 × 78

Is to be driven.

As a drive circuit for driving the active matrix type liquid crystal display panel 1 having such a structure, the structure shown in FIG. 12 is used in this embodiment. That is, the drive circuit is composed of the data electrode drivers 2 and 3, the scan electrode driver 4, the data processing circuit 15, and the timing generation circuit 16.

The data electrode drivers 2 and 3 drive the odd-numbered and even-numbered data lines of the data lines 6-1 to 6-1680, respectively, and have 840 outputs, respectively.

The scan electrode driver 4 is connected to the scan line 8-1.

The scan electrode driver 4 is controlled to drive (an odd number of 1559 to 1559) in a time-divisional manner within one horizontal scanning period, and the data driver control signal Dcon is output to drive the scan line 8-i during the driving period. Data lines 6-1 to 6-167

During the driving period of -i + 1, the data lines 6-1 to 6-16
The data electrode drivers 2 and 3 are controlled to apply even line data to 80 (even number).

13 and 14 are timing charts for explaining the operation of the drive circuit of this embodiment. As shown in the figure, in this embodiment, the display data for one line is divided into odd line data and even line data, and is written in one horizontal period in a time division manner. Further, in synchronization with this, the scan electrode driver 4 outputs a scan voltage. That is, the scanning voltage is output to the first scanning line for 1-line (odd number) data and the second scanning line for 1-line (even number) data, respectively. By repeating this, 1560 scanning lines are driven in one frame period (one vertical period). Second Embodiment FIG. 12 shows a configuration diagram of an active matrix type liquid crystal display device and a driving circuit thereof according to a second embodiment of the present invention. The structure of the second embodiment is the same as that of the first embodiment.

That is, as a drive circuit for driving the active matrix type liquid crystal display panel 1 having the configuration of FIG.
The data electrode drivers 2 and 3, the scan electrode driver 4, the data processing circuit 15, and the timing generation circuit 16 are included.

The functions of the data electrode drivers 2 and 3, the scan electrode driver 4, and the data processing circuit 15 are the same as those of the first embodiment. The timing generation circuit 16 divides one vertical scanning period into a first period (odd frame) and a second period (even frame). Applying data, one scan line 8 for each display line
-I (i = 1 to 1559 odd number) are sequentially driven, and in the even frame, the data lines 6-1 to 6-1680 are driven.
Even line data is applied to (even number) so that only the other scanning line 8-i + 1 is sequentially driven for each display line so that the horizontal synchronizing signal Hsync and the vertical synchronizing signal V
The sync driver outputs the scan driver control signal Scon and the data driver control signal Dcon to control the data electrode drivers 2 and 3 and the scan electrode driver 4.

15 and 16 are timing charts for explaining the operation of the drive circuit of this embodiment. As shown in the figure, in the present embodiment, first, in the odd-numbered frame, the data of the odd-numbered line data among the display data for one line is set to 1
Writing is performed in the horizontal period, and in synchronization with this, the scan voltage is output from the scan electrode driver 4 of the odd line. Then, in the next even frame, the even line data of the display data for one line is written in one horizontal period, and the scan voltage is output from the scan electrode driver 4 in synchronization with this. That is, 1
So-called interlaced scanning is performed in which 780 lines (odd scanning lines) are scanned during a frame period (odd frame) and 780 lines (even scanning lines) are scanned during a next frame period (even frame).

As described above, in the first and second embodiments, in the active matrix circuit configuration, one display line in the scanning direction is composed of two scanning lines (gate bus), and the same data line is used. When two connected TFT gates G1 and G2 are independently connected to two scanning lines to form two display pixels and color display is performed, the red pixel electrode R and the green pixel are arranged in the horizontal direction. The pixel electrode G and the blue pixel electrode B are arranged in order to form one color pixel,
Two scan lines are driven in a time division manner to display.

As a result, as shown in FIG. 17, the number of drive circuits is doubled on the scan electrode side, but is halved on the data electrode side, which is about three quarters as a whole. In the current technology, the circuit cost is data electrode side: scan electrode side = 3:
Since it is 1, the overall cost reduction rate is about 3/5
Becomes Further, the connection pitch is halved on the scanning electrode side, but doubles on the data electrode side. Since the pixel configuration of the display panel for OA use is a vertical stripe, the pixel pitch is, for example, 0.1 mm on the data electrode side and 0.3 mm on the scanning electrode side, and even if the scanning side is halved, the connection yield is particularly high. Is never reduced.

j) (i = 1 to N, j = 1 to M), the red pixel electrode R, the green pixel electrode G, and the blue pixel electrode B are sequentially arranged in the lateral direction to form one color pixel.

For example, as shown in FIG. 19, in a display panel having N = 16 display lines in the scanning direction,
16 × 2 scan lines are used as the first scan lines 8-1 to 8-
16 and the second scanning lines 9-1 to 9-16, and groups (10-1 to 10-) each having N routes = 4 lines.

In this active matrix type liquid crystal display device, one of the groups of the first scanning lines 8-1 to 8-N and one of the groups of the second scanning lines 9-1 to 9-N are used.
One of them is selected in time division, and the first scan line 8-i and the second scan line 8-i are selected.
Display data is written to the pixel electrodes 1 (i, j) (j = 1 to M) on the display lines in which both the scanning lines 9-i are simultaneously selected, and line-sequential scanning is performed to display.

In this embodiment, as an example, 640 ×
An active matrix type liquid crystal display panel 1 having 400 color pixels (the number of pixels is 6420 × 3 × 400) is a driving target.

As a drive circuit for driving the active matrix type liquid crystal display panel 1 having such a structure, the structure shown in FIG. 18 is used in this embodiment. That is, the drive circuit is composed of the data electrode drivers 2 and 3, the scan electrode drivers 4 and 5, the data processing circuit 15, and the timing generation circuit 16.

The case of a book (FIG. 19) will be described as an example. For example, by outputting the drive voltage from the output driver Da1 of the scan electrode driver 4 and the output driver Db1 of the scan electrode driver 5, the drive voltage is applied to the scan line groups 10-1 and 11-1. As a result, in the first display line, the upper and lower two TFT gates T1 and T2 are both turned on, and the data signal is written in the pixel electrode.
Only the TFT gate T1 is turned on in the fourth display line, and only the TFT gate T2 is turned on in the fifth, ninth, and thirteenth display lines, so that no data signal is written to the pixel electrodes of the other display lines. . That is, writing is performed only when the two TFT gates T1 and T2 are simultaneously turned on.

FIG. 20 shows a timing chart for explaining the operation when there are 16 display lines. As shown in the figure, the output drivers Da1 to Da of the scan electrode driver 4 are shown.
4 and scan electrode driver 5 output drivers Db1 to Db4
From the above, one display line is selected at the timing when the drive voltage outputs are simultaneously turned on, and line-sequential scanning is performed from 1 to 16 lines.

As described above, in the case where the number of display lines on the scanning side in this embodiment is 400, it suffices to construct two scan electrode drivers 4 and 5 having 20 output drivers. The number can be greatly reduced.
