Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to improving the operability of a terminal device mainly including a keyboard and a C11ff' display device.

(Background Art) In the work of displaying a large number of characters on a CRr display device (hereinafter abbreviated as CR"T") and comparing and checking the displayed contents with other document contents, an operator You must be careful not to memorize the location of the inside correctly (1~) and not to misread it as a part you are not paying attention to.

Conventionally, there is a "cursor'" as a pointer for this purpose, but since it is a pointer for each character, when there are many displayed characters, the number of key presses to move it becomes extremely large.

Since the speed at which humans press keys is extremely slow compared to the speed at which they read characters, this large number of key presses is a major factor in lowering work efficiency.

Furthermore, since the display state of the part that the operator is paying attention to is the same as the display state of the part that the operator is not paying attention to, operational errors (misreading) due to unnecessary information are likely to occur, resulting in significant eye fatigue.

(Problem to be solved by the invention) In view of the above-mentioned problems, it is an object of the present invention to provide a method for highlighting arbitrary positions of a display character list on CI(,T) line by line by pressing a key. The purpose of this feature is to significantly reduce errors, eye strain, and the number of key presses.Reflexon is a display system for a display device that has a screen that displays display data stored in memory and a keyboard that controls the display. In, Refresh 3
- the memory has information regarding the brightness of the display, the keyboard has a line movement key for moving a specified line, and a brightness change key for changing the information regarding the brightness, and when the brightness change key is operated, the specified line A display control method for a display device that controls the brightness of a display device.

(Structure and operation of the invention) FIG. 1 is a block diagram for explaining one embodiment of the present invention, in which 1 is a main control unit (hereinafter referred to as CPU), 2 is an input device, such as a keyboard device. be. 3 is T”
Di') device, 4 is the main memory (MN member V), 5 is the font memory (]aNi'), 6 is the refresh memo IJ
(REF), 7 CRT control & ft, 8 C
RT

In such a configuration, data input from the keyboard device 2 or data input from a host device (not shown) is temporarily stored in the information 4. Also, if necessary, FDD
3 is also stored. Furthermore, they are displayed on the CRT 8 in the order in which they were input. CR, 'I' When displaying on 8, CR
, T8 are stored in the refresh memory 6. Character codes of display data are stored in the refresh memory 6 in correspondence with display positions of T8. This refresh memory 6 stores line attributes and character codes as shown in FIG. 2 (1), and the line attributes are as shown in FIG. It includes a brightness designation part, a standard brightness designation part, and a high brightness designation part, and is provided for each row.Also, the alphanumeric characters in 0 in Figure 2 (1) l are located at the left end in Figure 2 (a) in the row attributes. In the character code, the alphanumeric characters on the left side of 0 are rows, and the alphanumeric characters on the right side are columns. Characters, symbols, etc. expressed in code are displayed.

Next, a display method of a display according to an embodiment of the present invention will be explained with reference to the display screen of FIG. Note that the keyboard device 2 has a brightness change key (for changing the brightness of lT8).
IcI u and the down key that moves the cursor position to the line at the bottom of the screen as a line movement key to move the specified line.
[)] ''' and an up key T + m 11 to move the cursor position to the upper line of the screen. In this state, when comparing the displayed content with other document content, use the down key or up key to move the cursor to the comparison position (100 in FIG. 4).

If the brightness key is pressed here, the line attribute of cl (FIG. 2) is changed and all displayed characters, symbols, etc. on the line where the cursor is located are emphasized (110 in FIG. 4). This is set as the emphasis mode.

This highlighting method is as follows: (1) The line where the cursor is located is designated as high brightness. The other rows are standard brightness or low brightness. (
2) Leave the line where the cursor is as is and specify low brightness for the other lines. There are other methods. Figure 3 (1)) shows the first
A case is shown in which the cursor is on a line and the brightness key is pressed on the first line, and in this case, the first line in the shaded area is all highlighted. When performing the above comparison at another position while in the above emphasis mode, use the down key or up key to move the cursor to the desired position.The previously highlighted line will be displayed normally and the new line will be highlighted. be done.

FIG. 3(C) shows a state in which the cursor has been moved to the second line using the down key from the state in FIG. 3(1)),
Figure 3 (Similar to bl, the shaded area shows the highlighted area. When the above work is completed and there is no longer a need for highlighting, just press the brightness key again to cancel the emphasis mode ( 120 in Figure 4).

In this way, the brightness key has a lock function that performs a toggle operation to switch between the emphasis mode and modes other than this each time the key is pressed.

In the above explanation, a lamp that lights up when in emphasis mode is attached to the brightness key, but operability for the operator is improved by displaying that it is in emphasis mode on the CR and T screens.
Of course it will.

(Effects of the Invention) As described above, the present invention has the following effects.

a) Since only the desired part on the CR,T is highlighted and the other parts are not highlighted, errors in work (misreading) and eye fatigue are reduced.

1)) Since the highlighted part is moved line by line, the number of key presses required for movement is reduced.
