Description

DETAILED DESCRIPTION OF THE INVENTION (1) Technical Field of the Invention The present invention relates to a cursor display method in a display device.

(2) Prior Art and Problems In display devices consisting of a display section and a keyboard, a method of displaying a cursor on the display screen is widely adopted in order to facilitate character input from the keyboard. This cursor uses a rectangular display, an underline, etc. to clearly indicate the position where input should be made.
Normally, this cursor blinks at regular intervals.

As is well known, the cursor moves to the next display position on the right as characters are input from the keyboard.

Therefore, the above-described display device that causes the cursor to flicker has the drawback that when the operator operates the keyboard, the operator loses sight of the displayed position of the cursor momentarily.

(3) Purpose of the Invention The present invention was made to solve the above-mentioned drawbacks, and its purpose is to provide a cursor display method that facilitates character input by continuously displaying a cursor when characters are input from a keyboard. shall be.

(4) Structure of the Invention The present invention includes a display unit, a keyboard, and a first signal generating means for generating a luminance signal for displaying a blinking cursor on the display screen of the display unit, In a display device in which a cursor moves to the next display position in response to an input, a second signal generating means for emitting a luminance signal for displaying a cursor on the display screen at a constant brightness, and a discrimination device for discriminating an input signal from the keyboard. means, a switching means for switching between the first signal generating means and the second signal generating means, and a control means capable of variably setting a time for returning the switching means, wherein the cursor is placed on the display screen. When an input is made from the keyboard while the cursor is displayed in a blinking state, the cursor is displayed at a constant brightness and moved to the next display position, and after a time set in the control means has elapsed, the cursor becomes blinking. This is a cursor display method that is characterized by displaying a cursor.

(5) Examples of the invention The present invention will be explained below with reference to the drawings.

The drawing is a block diagram illustrating one embodiment of the present invention, in which 1 is a screen, 2 is a cathode ray tube, 3 is a brightness modulation section, 4 is a keyboard, 5 is a control section, 6 is a clock generation section, 7 is a control circuit, 8 is a discrimination section, 9, 10
11 is a signal generation section, 11 is a switching section, 12 is a delay circuit,
a, b are display positions, C is a cursor, D is input data, E, F are brightness control signals, G is grit, H,
H' is a switching signal, I is a key, P is a clock pulse, R is a variable resistor, and T is a time.

A signal generator 9 in the figure generates a brightness control signal E that causes a cursor C to blink on the screen 1 (the cursor blinks every T seconds), while a signal generator 10 causes a cursor C to blink on the screen 1. It has means for generating a brightness control signal F for displaying at a constant brightness.

Since the switching unit 11 is always connected to the contact A side, the cursor C on the screen 1 is displayed blinking every T seconds.

As shown in the drawing, if the key I of the keyboard 4 is operated with a blinking underline cursor C displayed at the bottom of the display position a, input data D is sent to the control unit 5. , characters inputted at display position a on screen 1 (characters based on input data D) are displayed. At the same time, the cursor C moves to the display position b on the right (the control section related to character display and cursor movement is the same as in the conventional system, so it is omitted).

When the input data D obtained by operating the key I of the keyboard 4 reaches the determining section 8, the determining section 8 issues a switching signal H, so that the switching section 11 is switched to the contact RO side. For this reason, the brightness control signal F is sent to the brightness modulation unit 3 of the cathode ray tube 2, so that the cursor C on the screen 1 does not blink even when moving to the display position b on the right, and is displayed at a constant brightness. It will be moved in a state.

On the other hand, since the switching signal H drives a delay circuit (for example, a monostable circuit), the switching section 11 is returned to the contact A side by the signal (switching signal) H' output after the delay time t.

Therefore, since the brightness control signal E is sent out, the cursor C, which has also been moved to the display position b, is displayed blinking again.

Note that by changing the value of the variable resistor R, it is possible to adjust the delay time t.

(6) Effects of the Invention As described above, the present invention has a means for displaying the cursor at a constant brightness during input by operating the keyboard, so there is no risk of the operator losing sight of the cursor while operating the keys. This has the advantage of further improving operability.
