The operation of the automatic display on / off apparatus according to the embodiment of the present invention by the above configuration is as follows.

First, when power is applied to the automatic display on and off device, the controller 1 initializes and sets the operating environment of the automatic display on and off device according to the flowchart of FIG. 3.

The ROM section 4 contains program data for making a command according to the flowchart shown in FIG. 3, and the control unit 1 reads the data so that the off time and the on time are in the automatic display off and on registers. Instructions for setting are performed.

The control unit 1 operates the display of the display unit 2 and repeats the operation of turning on the display of the display unit 2 if it does not check by determining whether the key and the timer are checked.

The controller 1 checks the timer if no key is input and increments 1 second if 1 second occurs, and returns to the key check determination step if 1 second does not occur and checks the key to input a key from the key matrix 3. If so, the key is input, the keys are sorted, the display on register is cleared, the key routine is performed, and the display of the display unit 2 is turned on again.

The controller 1 determines whether it is day or night, and if it is day, it determines whether the current time is equal to the automatic display off register time.

Then, if the current time is equal to the automatic display off register time, the control unit 1 gives the display register a delay of 299 seconds, turns off the display, checks the key and timer again, and the current time matches the automatic display off register time. Otherwise, it determines whether the delay of the display-on register is 299 seconds.

In addition, if the delay time of the display on register is equal to 299 seconds, the control unit 1 switches to the clock mode, clears the display on register and turns on the display of the display unit 2. Otherwise, the control unit 1 is set to 1 in the display on register. The delay time is added to the second, and the display of the display unit 2 is turned on.

The controller 1 judges the time and, if it is night, determines whether the current time is equal to the automatic display off register time.

If the current time is equal to the automatic display ON register time, the controller 1 clears the display ON register, turns on the display, and if it is different, determines whether the delay time of the display ON register is equal to 299 seconds.

If the delay time of the display on register is equal to 299 seconds, the control unit 1 turns off the display of the display unit, checks the key and timer, and if it is wrong, adds the delay time to the display on register by one second and turns on the display. The operation of the off device is made.

The effect of the present invention can reduce the power consumption by automatically turning on the display during the daytime when not in use, and automatically turn off the display during the night time without giving inconvenience to users of the product. .
