Abstract

PURPOSE:To enable the erasing and writing of characters in optional positions at a high speed with a panel of large display capacity which can display many characters, by separating a liquid crystal which uses a small number of electrodes and is fast in response and a liquid crystal which is slow in response and uses a large number of electrodes in >=2 regions, and providing scanning electrodes and signal electrodes so as to intersect with each other in the respective regions. CONSTITUTION:Just one line - several lines can be displayed in a monitor region as shown by (a) in the input operation of a composite liquid crystal display panel, but 1-40 lines can be displayed in a main display region B. The display on such composite liquid crystal and the writing of documents are accomplished in the region A. For example, the operator inputs and displays ''it is fine today'' in the region A and instructs the movement if there are no errors, then the displayed content is moved as it is to the 1st line of a main display region B as shown by (b). The content of the 2nd line is then made in the region A and is moved to the region B. The display region A of small capacity which uses a small number of electrodes and is fast in response is used for the part where writing and correction are carried out frequently and the display region B of large capacity consisting of the liquid crystal using many electrodes is used as a large image plane area and the displayed contents are made movable between both display regions.

ている。However, because these terminal display devices display a large number of characters and types of characters, unlike segment-type displays such as those used in calculators and watches, multiple scanning electrodes and multiple signal electrodes intersect, and there is a gap between the two electrodes. By interposing a layer of liquid crystal between the dots and selecting the intersection points to which voltage is applied, the structure is such that any combination of dots can display arbitrary characters.

多数の電極を近接配置することができない。This is called a matrix type LCD, and in order to achieve an easy-to-read display with high dot density, it is necessary to increase the number of dots by increasing the number of electrodes. However, with the commonly used TN (twisted nematic) liquid crystal,
Due to the crosstalk effect, it is difficult to obtain a sufficient drive margin when the number of scanning electrodes is increased, and it is impossible to arrange a large number of electrodes close to each other in a limited area.

FIG. 1 shows the display section of the composite liquid crystal display panel, where A is the monitor area and B is the main display area. The monitor area A is composed of a TN liquid crystal, and the main display area B is composed of a memory liquid crystal such as a cholesteric nematic phase transition mode liquid crystal.The monitor area A is an area that displays the content currently being input. Therefore, only a limited number of lines is required.Moreover, since the monitor area A is composed of a TN liquid crystal in this way, scanning is performed in such a way that it is not affected by the crosstalk effect. The number of electrodes is limited.As a result, the display area is narrow and only a few lines can be displayed.
Since it is sufficient to display a limited amount of content that is currently being input, there is no problem with the size of the display area. As shown in Table 1, TN LCD has a fast response speed, so it is suitable for displaying the content currently being input, and corrections to input content can be made quickly and freely. .

画面で構成される。The main display area B uses a liquid crystal with a memory effect, has electrodes arranged in high density, and has a large display capacity so that a large number of characters can be displayed. This main display area B is an area in which the contents input in the monitor area A are moved and displayed, and is composed of a screen having a size of, for example, JIS, ^5.

る。Therefore, by sequentially moving the content created in monitor area A to main display area B and displaying it, you can view the displayed content in a large area of about one page, so you can grasp the overall status and Suitable for checking relationships. However, as mentioned above, although a storage liquid crystal can have a large number of scanning electrodes, its response speed is slow. However, main display area B only displays the content created in monitor area A, and is not frequently erased or written to.
There is no problem even if the response speed is slow. If it is necessary to correct the content in main display area B, move only that line to monitor area A, make the correction in monitor area A, and then return it to the original line in main display area B. The contents in display area B can also be quickly and freely corrected.

As shown in (A), only one or a few lines can be displayed in the monitor area A, but as many as 1 to 40 lines can be displayed in the main display area B, for example. When a document is created using this composite liquid crystal display panel, it is mainly created in the monitor area A. For example, input and display "It's sunny today" in monitor area A,
If there are no mistakes as a result of checking, give the movement instruction,
The displayed content remains as it is in main display area B 1 as shown in (b).
Moved to line 1. Next, copy the contents of the second line to monitor area A.
, and move it to main display area B. By repeating such operations, the next line is created in the monitor area A and moved to the main display area B, thereby making it possible to display characters on the entire large screen of the main display area B. The content created and displayed in monitor area A is displayed in main display area B.
The operation to move to the main display area B may be executed by the operator issuing a special movement instruction, or the movement to the main display area B may be executed automatically when the displayed content fills the entire screen of the monitor area A. You may also do so.

移動させる。FIG. 3 is a diagram showing an operation when partially correcting the display contents in the main display area B. As shown in (A), the line number l in the main display area B corresponds to each line. For example, in the second line that says "40% chance of rain tomorrow", "40%" is displayed.
If the error is "50%", specify the line number and temporarily move the contents of the second line to the monitor area A as shown in (b).

る液晶表示パネルと同一機能を得ることができる。In this way, a small-capacity display area (A) made of a liquid crystal with a small number of electrodes but a fast response and a large-capacity display area (B) made of a storage liquid crystal with a large number of electrodes are separated. It is arranged. A small-capacity display area (A) made of a liquid crystal with a small number of electrodes but with a fast response is used for areas where writing and correction are frequently performed, and a large-capacity display area CB made of a liquid crystal that can have a large number of electrodes. By having a large screen area and making it possible to move the displayed content between the image display areas, it is possible to obtain substantially the same function as a liquid crystal display panel that can perform erasing and writing at high speed on a large-capacity screen.

使用することもできる。Although the TN liquid crystal is exemplified as a liquid crystal that has a small number of electrodes but has a fast response, other types of liquid crystals may be used as long as they have similar characteristics. In addition, as an example of a liquid crystal that can have a large number of electrodes, a cholesteric nematic phase transition mode memory liquid crystal has been shown as an example. It is also possible to use a DSM (dynamic scattering mode) liquid crystal that can have a steep threshold voltage.

り、違和感がなくなる。In FIGS. 2 and 3, the monitor area A is placed at the top of the main display area B, but it may be placed at the bottom, that is, below the 40th line. According to this, the text created in monitor area A is always moved to line 40, and the content from line 39 onwards that has already been moved to main display area B is sequentially shifted upward one line at a time. , just like when actually handwriting, the screen is filled in toward the bottom, which eliminates the sense of discomfort.

(a) is a plan view of the panel, and (b) is a side view of the panel. The panel is constructed by stacking a transparent upper plate 2 and a lower plate 3 and pasting them together using sealing parts 4a and 4b made of adhesive, and sealing the gap by injecting TN liquid crystal from the injection port 5a.Note 10 - A liquid crystal with a large operating margin, such as a storage liquid crystal, is injected from the inlet 5b and sealed. As a result, a monitor area is configured in the area A surrounded by the seal part 4a, and the seal part 4
The main display area is configured in the area @B surrounded by b. Upper plate 2
Electrodes 6a and 6b patterned in the horizontal direction in the figure are scanning electrodes, and electrodes 7a and 7 patterned in the vertical direction in the figure in the monitor area A and main display area B are scan electrodes.
b is a signal electrode formed on the inner surface of the lower plate 3; The signal electrodes 7a, 7b are connected to lead patterns 8a, 8b on the upper plate 2 in a direction perpendicular thereto. As a result, all the electrodes are concentrated on the upper plate 2,

である。Actually, a polarizing plate is stacked on the upper plate 2, and a polarizing plate and a reflecting plate are stacked on the lower plate 3. Note that the upper plate 2 and the lower plate 3 are transparent, and even in the plan view of (a), the seal portions 4a and 4b between the upper plate 2 and the lower plate 3 and each electrode are drawn so as to be visible from the outside. Of course, each electrode is also transparent.

Then, the elastane ink connector 10 is inserted above the signal electrode 7b, and the connector IO (
As shown in c), the signal type m7b is connected to the liquid crystal drive circuit on the printed circuit board 11. Other signal electrodes are led out to the upper plate 2 as indicated by 8b in the same manner as the signal electrode 7a in FIG.

なる。In this way, by leading every other electrode to the opposite side to reduce the pinch of the signal electrode, it is possible to further increase the display capacitance of characters. By arranging the electrode lead-out pattern, the electrode pitch can be reduced.Also, by increasing the number of dots in this way, graphic ink display is also possible.

For example, monitor area A is placed at the 20th line position in main display area B in FIG. , so that the text created in monitor area A is always moved to the 19th line immediately above, and the display above from the 19th line in the main display area is shifted upward one line at a time each time it is moved. You can also do it. When you want to correct a part of an already completed sentence as shown in Figure 3, specify the line you want to correct, and the entire text will scroll upwards or downwards, and the specified line will move to the monitor area in the middle. You can do it like this. According to this, since the preceding and succeeding sentences are placed one above the other, corrections can be made while easily checking the context of the sentences.

The structure is such that scanning electrodes and signal electrodes are provided in a crossing manner in each region. Therefore, a liquid crystal with a fast response speed is used to configure the monitor area where writing and corrections are frequently performed, and a liquid crystal with a slow response speed but with a large number of scanning electrodes is used to configure a large screen with a large display capacity. By allowing the displayed contents to be freely moved between the two, it is possible to obtain the same effect as writing and correcting at high speed on a large screen with a substantially large display capacity.
