Abstract

PURPOSE:To constitute the title system so that displayed characters can be classified separately and clearly by varying the display direction length, in case a display mode of other part than a character part in one unit display area is the same as a display mode of its adjacent unit display area. CONSTITUTION:A display means 12 in which unit display areas for displaying a character to be displayed, respectively have been set in a matrix shape is prepared. Subsequently, at the time of displaying a character in a unit display area 62, in case it has been judged that a display mode of other residual part than a character part is the same as a display state at least in the vicinity of the side end part of one unit display area of the adjacent unit display area along the display direction of the character, a classification is performed against the adjacent unit display area by varying the display direction length of the one unit display area 62. In such a way, the characters displayed on the display means 12 can be classified mutually and clearly.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a method for displaying characters, etc. on a display device in which a unit display area is set for each character to be displayed.

2. Description of the Related Art In small-sized computers called calculators, liquid crystal display devices are used as output devices for various data such as calculation results. This liquid crystal display device is classified into a segment type and a dot matrix type. In the dot matrix method, dot-shaped pixels are formed in the display area, and a desired character or the like is displayed by changing the display mode of these pixels. Furthermore, when displaying characters on such a dot matrix type liquid crystal display device, the display area is divided into unit display areas of a predetermined size, and a desired character is displayed in each unit display area. . Such a unit display area is
For example, 8×16 dots are selected.

FIG. 8 is a diagram showing a display state of the display device 1 configured by a typical conventional liquid crystal display device or the like. In the conventional display device 21, the displayed characters (
For example, the hiragana "shi"> is, for example, a unit display area of 8 x 16 dots 2a, 2b, 2c, ... (hereinafter referred to as
(referred to as unit area; when collectively referred to, it is indicated by reference numeral 2)
displayed every time.

Such a display device 1 is used, for example, as a display device of a text processing device called a so-called word processor. That is, for example, a sentence to be input in hiragana is input, and then a hiragana/kanji conversion key provided in the text processing device is operated to obtain a desired kanji display. In such a case, the hiragana display before pressing the hiragana/kanji conversion key is 6, in which the character "shi" is displayed in reverse in a so-called white state, as shown in the unit area 2C of FIG. The shaded area in FIG. 8 is, for example, an area that is visually recognized as black. When a hiragana/kanji conversion key or the like is operated on such a reversely displayed hiragana column, the desired kanji is displayed in black.

Problems to be Solved by the Invention When using the display device 1 as described above, if an error occurs when inputting a hiragana character, the cursor that displays the input location of the character can be moved to place it on the erroneous character. Move the cursor and input legal characters.

At this time, for example, the unit area 2b where the cursor is superimposed
The display mode switches between an inverted (white) display of the character and a non-display state, thereby realizing a display mode in which the inverted display character blinks, making it easy to determine the placement position of the character to be corrected. I'm trying to get recognized.

In such a case, in the unit area 2a of the next character to be displayed, the character "shi" is also displayed inverted (outlined), and therefore the unit area 2a in FIG.
, 2b, the character “shi” and the unit area 2b
The display mode of the non-display period becomes the same, making it impossible to distinguish between the two, and the unit area 2b to which the cursor was moved
There is a problem in that it becomes difficult to recognize the character in the unit area 2a that follows.

In order to solve this problem, in each unit area 2, the 16 dots at the right end of Figure 8 are designated as division area 1 or 3 (area shown surrounded by a two-dot chain line in Figure 8), and this is set to the lighting state. It is envisaged that the technology will leave it as is. In this way, the dividing area 3 separates the displayed characters in the unit area 2 adjacent to the right in FIG. 8, and the above-mentioned problem is solved. However, in such technology, the rightmost unit area 2 of the display device 1
In a, the classification area 3 at the right end remains lit pointlessly, and the power consumption increases unnecessarily.
There is a problem in that it becomes an impediment to realizing efficient display operations.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems and to provide a display method in which displayed characters can be clearly distinguished individually and display effects can be significantly improved.

Means for Solving the Problems The present invention comprises a display means in which unit display areas for displaying characters to be displayed are set in a matrix, and in one unit display area, the remaining parts other than the character part are displayed. If the aspect is the same as the display aspect of at least the one unit display area side end of adjacent unit display areas along the display direction of the character, the length of the one unit display area in the display direction is changed. This is a display method characterized by the following.

According to the present invention, a display means is prepared in which unit display areas for displaying characters to be displayed are set in a matrix. When displaying a character in a unit display area, the display mode of the remaining part other than the character part is the same as the display mode of at least one unit display area side edge of the adjacent unit display area along the display direction of the character. If it is determined that the unit display area is the same, the length of the unit display area in the display direction is changed so that a division is made between the unit display area and the adjacent unit display area.

On the other hand, if the above-mentioned condition is not satisfied, the process of changing the length of the unit display area in the display direction is not performed, and in the unit display area at the end of the display means along the display direction, the length in the display direction is undesirably changed. The change process is performed to prevent an undesired display mode from being realized. Thereby, the characters displayed on the display means can be clearly distinguished from each other, and an efficient display operation can be realized.

A conversion key 54 for converting inputted kana characters into kanji characters, a cancel key 55, an adoption key 56, a new line key 57, and an input key 58 are provided.

FIG. 4 is a diagram showing the stored contents of the display buffer 59 set in the RAM 18. The display unit 12 of this embodiment is realized by, for example, a liquid crystal display element, and the displayed characters are, for example, 8×16 dots. It consists of pixels. Therefore, characters to be displayed are stored in the same bit pattern in the display buffer 59 as well.

That is, the display buffer 59 is divided, for example, into unit storage areas 60a, 60b, . . . (generally referred to by reference numeral 60 when necessary) of 8×16 bits. Each unit storage area 60 stores one character. Note that the unit storage area 60a corresponds to the rightmost display area on the display section 12.

FIG. 5 is a flowchart for explaining the moving cattle of this embodiment, FIG. 6 is a diagram showing the display state of the display section 12, and FIG. 7 is a diagram showing an example of the display on the display section 12. . This embodiment will be described with reference to these drawings. First, in step n1, the processing device 1 that is powered on
1, the memo key 34 is operated. As a result, the processing device 11 is set to a mode for inputting text using the character input key group 29. Following the settings, the processing device 11
Determine whether the input mode is kana manual mode. If negative, operate key 44 at step n3.
, return to step n2. If the determination at step n2 is affirmative, then at step n4, the desired character is input using the character entry key group 29.

In step n5, the input characters are stored in the display buffer 59 in the RAM 18, and in step r, the stored contents are displayed in reverse on the display section 12. This state is shown in FIG. 6(2). Next, in step n7, it is determined whether a kana/kanji conversion operation has been performed to convert the input hiragana string into kanji as shown in FIG. 6(2). This operation is performed by operating the conversion key 54. If the determination is affirmative, in step n8, the dictionary function stored in the ROM 17 shown in No. 1I2I is searched to extract the corresponding kanji, and for example, as shown in the character "upper" of the unit storage area 60d in FIG. is memorized.

If the determination in step n7 is negative, it is determined in step n9 whether or not to perform the correction work. If this judgment is negative, the process returns to step n4, and the processes of steps 04 to n9 are repeated; if the judgment of step n9 is affirmative, the process proceeds to step n10, where the cursor key group 27. to move the cursor 61 shown in FIG. 6 to the desired display position. In other words, the explanation will be based on the assumption that, as shown in Figure 6 (2), when "Hashibashi" should have been entered, "Hashihishi" is entered incorrectly as shown in Figure 6 (3). .

In such a case, move the cursor 61 to the character "hi".
move above. Such a movement operation of the cursor 61 designates, for example, the start address of each unit storage area 6o shown in FIG. 4 in the display buffer 59. In the following description, when the cursor 61 moves to the second character position from the rightmost end on the display section 12, that is, in the display buffer 59, the unit display area 6
The following explanation assumes that 0b is specified. step n
In il, the unit storage area 60 following the unit storage area 60b
The first along the arrangement direction of a (direction toward the right in Fig. 4)
The 16th bit row of dots is scanned. subsequent step n
At step 12, it is determined whether or not there is a display dot. If there is a display dot, then in step r113, the blinking width N of the character on which the cursor 61 is placed on the display section 12 is decremented by one.

Here, the blinking width N is usually 8 bits, for example,
Therefore, in the display example of the display section 12 shown in FIG.
Unit display areas 62a, 62b, . . . each 8×16 dots
- When the cursor is placed on a unit display area 62b (generally referred to by reference numeral 62 when necessary), the entire unit display area 62b blinks.

If the determination at step n12 is negative, the process moves to step rr14 without passing through step n13.

In step n14, the character to be displayed is displayed blinking. That is, if the determination at step n12 is negative, the blinking width N is 8 bits, and therefore, for example, the 8x16 unit display area 62b shown in FIG. 7(2)
The dot part flashes, while in step n12
If the judgment is affirmative, the blinking width N is 7 bits, and therefore the rightmost 1×16 dot in the unit display area 62b continues to be lit.

Therefore, the problem with the prior art explained with reference to FIG. 8 can be solved by the dividing strip 63 displayed in this way. In other words, a situation in which the display character in the unit display area 62a becomes the same as the display mode when the unit display area 62b is not lit and becomes impossible to identify is prevented.

Further, if the display position to be corrected is the rightmost end of the display section 12, that is, the unit display area 62 in FIG. 7(2)
If a is to be corrected, step nl 1. n1
2, the next succeeding unit storage area 60 does not exist, so the determination at step n12 is negative, and step n
The blinking display of the character is performed without performing the processing described in No. 13 above. Thereby, even if a blinking display is performed in the unit display area 62a, it is possible to prevent the occurrence of an undesired display as described in the related art.

Following the above-described processing, a desired correction operation is performed in step n15, the cursor 61 is returned to the desired position in step n16, and processing such as input is continued.

As described above, in this embodiment, the characters displayed on the display unit 12 can be immediately and easily identified even if the characters are blinking due to the above-described correction operation. Further, it is possible to prevent an undesired display from occurring at the rightmost end of the display section 12.

According to the present invention as described above, the display mode of the remaining portion other than the character portion in the unit display area is such that the display mode of the remaining portion other than the character portion in the unit display area is at least at the end of the adjacent unit display area on the side of the one unit display area along the display direction of the character. If it is determined that the display mode is the same as that of the adjacent unit display area, the length of the unit display area in the display direction is changed to create a division between the unit display area and the adjacent unit display area. On the other hand, if the above-mentioned condition is not satisfied, the process of changing the length in the display direction of the unit display area is not performed, and the length in the display direction is undesirably changed in the unit display area at the end of the unit display area along the display direction in the display means. Length change processing is performed to prevent an undesired display mode from being realized.This makes it possible to clearly distinguish the characters displayed on the display means from each other, and also to efficiently Display operations can be realized.
