Abstract

PURPOSE:To contrive the improvement of the man-machine interface without damaging the emitting face of a display device by displaying only a field to be inputted at the position of a cursor in all input enable fields so as to allow an operator to confirm a maximum input character string. CONSTITUTION:In synthesizing a display data field and a cursor by the refresh counter 6 of a field generation system, a pulse is counted to update the display on the screen of the display device 5 and a display updating coordinate address is generated at high speed. Moreover, a cursor coordinate address instructed by a display control means is stored in a cursor coordinate register 7. The coincidence between the registers 6, 7 and the cursor coordinate address of an input enable field setting plane 1 is detected by a coincidence circuit 8 and the read of a field read circuit 10 is continued until the comparison section 9 confirms the setting of the plane 1. Then the data is processed by the synthesis circuit 4 and only the input enable field is displayed on the screen of the display device.

Description

[Detailed Description of the Invention] [Summary] The present invention provides an inputtable field generation method to be displayed on a display screen, which includes a comparison unit for a cursor coordinate address and an inputtable field coordinate address, and an inputtable field generation method corresponding to the cursor coordinate address. The field reading section that reads fields generates only inputtable fields of arbitrary length corresponding to the cursor coordinate address on the screen, clearly indicating the recognition of inputtable fields on the display screen, and does not shorten the life of the display. This is what made it possible.

[Industrial application field]

The present invention relates to a field generation method that allows inputtable fields to be displayed on a display screen as an output device of a computer or the like in a manner that is easy to see and does not damage the light emitting surface of the display.

In recent years, new media such as the Captain System have been put into practical use one after another, and word processors, personal computers, etc. are being used in offices and factories, and the role of displays is increasing. It is often necessary to input information and display an input area. This input possible area (
Man-machine ink for displaying inputtable fields (fields) that are easy to see on the face and that do not damage the fluorescent surface of displays such as CRTs [Prior art] In computer systems, data and When inputting messages manually using a keyboard, etc., it is common practice to display the input start position with a cursor on the display screen. Areas or input-enabled fields are generated and displayed on a display screen.

FIG. 5 is a block diagram employing a conventional inputtable field generation method. In this conventional method, an inputtable field setting plane 100 is provided that stores in advance the positions at which inputtable fields should be generated corresponding to all display addresses on the display screen, and this plane is sequentially read out in response to address instructions from a refresh counter to generate fields. Part 10
2 and the synthesis circuit 103 to the display 104, the contents of the display memory 105 and the cursor generator 106.
It was intended to be displayed together with a cursor 107 generated from.

The conventional display display described above simultaneously displays all inputtable fields 108 in colored or white (inverted color) on the screen of the display 104, as shown in FIG.

[Problem that the invention seeks to solve]

However, in the above-mentioned conventional manual field generation method, all fields other than those specified by the cursor are also displayed, so if it is a CRT display, the light emitting surface ('W light surface) of the display part will be displayed. A so-called burning phenomenon occurred, which could damage the CRT and shorten the life of the cathode ray tube.

In addition, when an operator inputs data or messages, they often change their line of sight between the keyboard and the display, and in addition to the field they are trying to enter, fields that have not yet been entered are also displayed. There was a problem with the man-machine interface, which was difficult to see.

The present invention is intended to solve the above-mentioned problems, and an object of the present invention is to provide an inputtable field generation method in a display device that does not damage the light emitting surface of the display and can improve the man-machine interface. do.

[Failure to solve the problem]

FIG. 1 is a block diagram for explaining the principle of the present invention.

Means for achieving the above object of the present invention includes a comparison unit 9 that compares a cursor coordinate address and an inputtable field coordinate address and detects a match, and an inputtable field setting brain that sets an inputtable field corresponding to the matched address. This field generation method is characterized in that it is equipped with a field reading unit 10 that reads out fields from 1, and displays only inputtable fields corresponding to the current display position of the cursor on the screen of the display 5.

[Effect]

The cursor display indicates the position of data to be input from the keyboard or the like, and the input field displays the input character string length, such as the number of digits and characters of the data to be input. In the present invention, only the part of the inputtable field where the cursor is displayed is displayed, and when the cursor moves to another inputtable field, the previous inputtable field display disappears and only the inputtable field at the new cursor position is displayed. Therefore, when the operator shifts his line of sight to the screen, his line of sight immediately goes to the input field to which input is to be made, making it easier to see. Further, since necessary input fields are not displayed, there is less damage to the light emitting surface.

〔Example〕

An embodiment of the present invention will be described in detail below based on the drawings.

FIG. 2 is a prosock diagram of an embodiment to which the present invention is applied. First, I will explain its structure. The display device of this embodiment has an inputtable field (hereinafter abbreviated as field) in a part where the cursor is generated based on the memory of the inputtable field setting plane 1, and an inputtable field (hereinafter abbreviated as field) generated based on the memory of the inputtable field setting plane 1, and an inputtable field written in the display memory 2 from a display control means (not shown). Display data such as characters and symbols and a cursor generated by a cursor generating section 3 are synthesized by a synthesizing circuit 4 and displayed all at once on a display 5 such as a CRT.

The refresh counter 6 has a function of counting pulses and generating display update coordinate addresses at high speed in order to update the display on the display screen when synthesizing the display data, field, and cursor. Every time a count is made in the direction (X direction), an amplifier is counted in the vertical direction (Y direction). The cursor coordinate register 7 has, for example, an 8I function to hold a cursor coordinate address instructed by the display control means.

The configuration that generates the field includes an inputtable field setting plane 1, a match circuit 8 that detects the display update coordinate address of the refresh counter 6, a cursor coordinate address of the cursor coordinate register 7, and a match signal of the minus number circuit 8. A comparator 9 detects whether or not there is a field setting for the field setting plane 1 that can be entered at the display update coordinate address at that time, and reads out the field setting until the display is updated if the field setting is present. It consists of a field reading section 10, a field generating section 11 that generates fields from the read field setting data, and the like. For example, field settings for inputtable field setting plane l can be set by changing the field display coordinates to “
1", and other display coordinates are stored as "0". This inputtable field setting plane 1 is read out according to the instructions of the refresh counter 6. Therefore, the comparator 9 checks whether there is a field setting at the cursor coordinate address or not. That is, the cursor coordinate address and the field coordinate address are compared.

The field reading section 10 receives a signal indicating that the two addresses match, that is, an enable signal from the comparing section 9, and sends the subsequent data with field settings as valid to the field generating section 11. Data with field settings that are not consecutive (with 0" in between) is invalidated and is not input to the field generation section 11. However, in case the cursor is located in the middle of a field, the field reading section 10 It is also possible to hold the start coordinate address of the cursor coordinate address and generate a field by validating the field setting data before the cursor coordinate address at the next update readout.

The display memory 2 is read out according to the display update coordinate address of the refresh counter 6, and is further read out by the cursor generation unit 3.
receives the display update coordinate address and the cursor coordinate address, and generates a cursor to the synthesis circuit 4 when they match. Since the cursor generating section 3 also has a matching circuit for the cursor coordinate address and the display update coordinate address, the minus number circuit 8 may be used in common with this circuit.

The operation of the embodiment with the above configuration will be described. The field, cursor, and display data generated in each component are stored and sent out in character units, so when the synthesis circuit 4 calculates the logical sum of each data, each data is converted into a bit image using a character generator or the like. The synthesized bit image is stored, for example, in a bitmap memory.

This bit image is read out from the bitmap memory in rask format independently of the storage and displayed on the display 5 as shown in the example of FIG. According to the above configuration, input to one field using a keyboard is completed,
When the cursor 12 moves to the next field by operator operation or automatically, the inputtable field 13 corresponding to the cursor coordinate address is displayed, and the display of the previously displayed inputtable field 13' disappears, and as the cursor moves, the inputtable field 13 corresponding to the cursor coordinate address is displayed. Only inputtable fields corresponding to the cursor coordinate address are displayed one after another.

It should be noted that the present invention is not limited to the above-mentioned embodiments, and can be applied in various ways and implemented in accordance with the gist of the present invention. For example, the display is not limited to a CRT, but can also be applied to a night crystal display or a plasma display. Furthermore, the field display method is not particularly limited, such as underline display or frame display. Further, in the above embodiment, processing is performed character by character, but processing may be performed in a bitmap format.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, only the inputtable field where the cursor is located can be displayed out of all the inputtable fields, so that the operator can immediately direct his/her line of sight to the input area. The maximum input string length can be seen at a glance, improving the man-machine interface. Further, since unnecessary input fields are not displayed, the light emitting surface of the display is not illuminated for a long period of time, and the light emitting portions of the input fields are not damaged.

Therefore, there is an effect that the life of the display is not shortened.
