Specifically, one of the pair of substrate members includes a common electrode, and the other substrate member includes a segment electrode corresponding to a pixel electrode. Each substrate member includes an alignment film that is in contact with the liquid crystal layer. In an unlit state where no display voltage is applied, the liquid crystal molecules of the liquid crystal layer are initially aligned in a state predetermined by the regulating force of the alignment film, and in a lighted state where the display voltage is applied, the liquid crystal molecules are aligned in the direction of the electric field. . Information is displayed by the light-off state and the light-on state based on the change in the alignment state of the liquid crystal molecules.

Further, the display device 1 includes the liquid crystal display units 10 and
14, the liquid crystal control units 11 and 15, the common drivers 12 and 16, and the segment drivers 13 and
17 are provided.

Lines for characters are composed of lines with a predetermined number of dots,
Specifically, the line feed detecting unit 25 is configured to set 1 for which all dots are turned off.
Display information in which blank lines, which are dot lines, are continuous for a number of times corresponding to the height of one character is detected as line feed information. Then, information indicating the presence / absence of a line feed and its position is compared with the comparison unit 28
And a line feed deletion unit 29.

The space position detecting section 26 detects space information, which is a single character line consisting of only blank lines existing between characters from the back of the display information stored in the upper screen bitmap 23, and outputs the space information. Detect if is on the last line. That is, the space position detection unit 26 is a component related to a detection unit that detects whether a character to be divided exists in the upper and lower liquid crystal display units 10 and 14 by dividing display information. When the space information is on the last line, there is no display information to be divided, and when the space information is not on the last line, it is determined that there is information to be divided. In the display device 1, display information for one character line is specific display information of a predetermined unit. Here, one character line is used. However, the present invention is not limited to one character line. For example, two or more character lines such as chapters and sentences may be used.

When the space position detecting section 26 first detects that the space information is on a line other than the last line, information indicating the position is given to the shift amount calculating section 27. The shift amount calculation unit 27 calculates a shift amount, which is an information amount after the position, and gives the calculated shift amount to the comparison unit 28.

The comparing unit 28 stores the shift amount calculating unit 2 within the information amount after the line feed position detected by the line feed detecting unit 25.
It is determined whether or not the shift amount calculated in Step 7 can be accommodated, and the determination result is given to the line feed deletion unit 29. When it is determined that the information can be accommodated, the line feed deletion unit 29 deletes the display information of the shift amount calculated from the information amount after the detected line feed position. Then, the display information after the deleted information is packed with the information before the deleted information, and the display information thus processed is provided to the upper screen bitmap 23 again.

The shift amount calculated by the shift amount calculating section 27 is also given to the moving amount calculating section 31.
The movement amount calculation unit 31 subtracts the given shift amount from the display information amount of a predetermined height of one character. That is,
The amount of display information divided by the lower liquid crystal display unit 14 is calculated. The calculation result is provided to the movement control unit 33. The movement control unit 33 extracts the display information of the amount calculated by the movement amount calculation unit 31 from the top of the lower screen bitmap 24 and adds the display information to the rear of the upper screen bitmap 23, thus moving the information. I do.

The shift amount calculated by the shift amount calculating section 27 is further provided to the lower screen extracting section 21. The lower screen extracting unit 21 re-extracts new display information corresponding to the given shift amount, that is, display information subsequent to the display information newly stored in the upper screen bitmap 23, from the bit information holding unit 6, The display information thus processed is provided to the lower screen bitmap 24. Specifically, the judgment result of the comparing unit 28 is also used as the lower screen extracting unit 2
1 is also given. Based on the determination result, the lower screen extracting unit 21 extracts the information to which the information of the shift amount is added as the lower display information when all the display information of one character line to be divided can be displayed on the lower side. Do it again. If all the display information for one character line to be divided cannot be displayed on the lower side, information obtained by subtracting the information of the shift amount is extracted again as the lower display information. Therefore, the line feed detecting unit 25, the shift amount calculating unit 27, the comparing unit 28, and the line feed deleting unit 29
It is a component related to a moving means for moving one information to the other information side or the other information to the one information side with respect to the specific display information to be divided.

When the line feed information is not detected by the line feed detecting section 25, the comparison result of the comparing section 28 is inverted by the inverter 32, and the output is supplied to the space inserting section 30. The space insertion unit 30 overwrites the space information by the shift amount from the rear of the information stored in the upper screen bitmap 23 and gives the space information to the upper screen bitmap 23. In this way, the display information divided upward is erased.

First, at step a12, the display information of the last one dot row of the upper display information 40c is fetched. In the next step a13, it is determined whether or not all of the acquired display information is space information. If it is not the space information, the process returns to step a12 to fetch the display information of the previous dot row by one dot, and repeats the processing of steps a12 and a13 until all the display information becomes a line that is space information. When all the lines are space information, the process proceeds to step a14, and the shift amount, which is the information amount acquired in steps a12 and a13, that is, the upper display information amount of the display information for one character line to be divided is calculated. I do. In the next step a15, display information for one character line to be divided is fetched.

Subsequently, in step a16, the line feed information is deleted based on the position information detected in the previous step, and in step a17, the display information after the line feed information is reduced to the information before the line feed. Step a18
Now, the display information captured in the previous step is added. Thus, the divided display operation ends.
