JPH04186285A - Display terminal lifetime information supply device - Google Patents

Abstract

PURPOSE:To improve the convenience of the use of a display terminal by notifying lifetime information such as the remaining time until the display terminal reaches the end of its life, information on the fact that the display terminal has reached the end of the life based on a set lifetime and an actual operating time measured by a timer. CONSTITUTION:A time memory 5 stores the total time measured by a timer 4, and a decision unit 8 compares the lifetime set in a lifetime setting unit 7 with the energizing time. When an operator turns on a life display switch 10, the total energizing time and the preset lifetime or the remaining time until the energizing time reaches the lifetime, are displayed on a life information display unit 9, and the operator knows the actual operating time of a CRT display 1 before the display reaches the end of its life, and can decide the replacing period of time of the display. Further, when the energizing time of the timer 4 reaches the lifetime, the display unit 9 automatically displays it, and thus fatigue of eyes, etc. due to the use of the degraded display can be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a lifespan information providing device that notifies lifespan information of a display screen used as a monitor of a computer or the like.

(Prior Art) Display terminals used as computer monitors and the like generally include CRT displays, liquid crystal displays, and plasma displays. Such display terminals have a limited lifespan and deteriorate over time, so they must be replaced periodically.

Conventionally, the time to replace the display terminal is notified to the user as a service provided by the manufacturer that delivered the display terminal. In other words, when a predetermined time or number of days has passed from the manufacturing date or delivery date, the manufacturer will notify the user, for example, ``X hours (Y years) have passed since delivery. The reality was that the company was encouraging people to replace their CRT displays by issuing notifications such as "It's time to replace your CRT display."

(Problem to be Solved by the Invention) However, the above conventional example is only a unilateral notification from the manufacturer, and is not based on actual operating time. Therefore, if the operating time is short, unnecessary replacement will be prompted, whereas if the operating time is long, the replacement will be notified after the deterioration has progressed considerably, which is not suitable for the actual situation.

The present invention has been made based on the above-mentioned circumstances, and an object thereof is to provide a lifespan information providing device for a display terminal that can easily notify accurate lifespan information without human intervention.

[Structure of the invention]

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a means for setting a life time of the display terminal in advance in a display terminal for monitoring such as an electronic computer, and an actual operating time of the display terminal. The present invention is characterized by comprising: means for measuring the life time; and means for creating and notifying the life information of the display terminal based on the set life time and the measured actual operating time.

(Operation) According to the present invention having the above configuration, while the life time of the display terminal is set in advance, the actual operating time of the display terminal is measured. Then, based on the set life time and the measured actual operating time, for example, a notification that the life time has been reached or life information such as the remaining time until the life time is reached can be notified.

(Example) Hereinafter, the present invention will be explained based on illustrated embodiments.

FIG. 1 is a block diagram showing the configuration of an embodiment of a display terminal life information providing device according to the present invention, and FIG. 2 is an external configuration diagram thereof.

This embodiment device uses a CRT display 1 as a display terminal.
This CRT display 1 is driven by a CRT controller 2.

Further, in order to particularly provide life information, a power supply detection section 3, a timer 4, a time memory 5, a battery 6, a life time setting section 7, a determination section 8, a life information display section 9, a life time The display switch 10 is configured to include a display switch 10.

The energization detection section 3 detects when the power switch 11 is turned on and starts a timer 4, and stops the timer 4 when the power switch 11 is turned off.

Timer 4 is the power supply time, that is, CRT display 1
It counts the actual operating time of

The time memory 5 accumulates and stores the energization time counted by the timer 4. This time memory 5 is backed up by a battery 6.

The life time setting section 7 sets and registers the life time of the CRT display 1 in advance.

The determination unit 8 compares the energization time cumulatively stored in the time memory 5 with the life time set in the life time setting unit 7 and supplies the determination result to the life information display unit 9.

As shown in FIG. 2, the lifespan information display section 9 is provided at the lower end of the display screen 12, and can be composed of, for example, a liquid crystal display. This life information display section 9 normally does not display anything, but when the life display switch 10 is operated, the accumulated energization time, that is, the CRT display 1
Displays operating hours, etc. Further, when the life time has been reached, a notification is given that the life of the CRT display 1 has expired, regardless of whether the life display switch 10 is operated.

In the above configuration, when the power switch 11 is turned on, the CRT
When the display 1 is put into a driving state, the energization detection section 3 detects energization and starts the timer 4 at that timing. The timer 4 measures the energization time, that is, the actual operating time of the CRT display 1, until the power switch 11 is turned off and the energization is cut off.

The time memory 5 stores the energization time measured by the timer 4, and the determination section 8 compares the life time set in the life time setting section 7 with the energization time.

During this time, when the operator turns on the lifespan display switch 0, the lifespan information display section 9 displays the total energization time and set lifespan time, or the remaining time until the lifespan is reached. Thereby, the operator can know the actual operating time of the CRT display 1 before it reaches the end of its life, and can accurately judge when to replace it.

On the other hand, when the timer 4 reaches the life time, the timer 4 automatically displays the information on the life information display section 9.
be made into For this reason, CRTs that have deteriorated over time and have reached the end of their service life.
Eye fatigue caused by using the display 1 for a long period of time can also be avoided.

In this embodiment, the CRT display 1 is used as an example of a display terminal, but the present invention is not limited to this and can be applied to various display terminals such as a liquid crystal display and a plasma display. Further, the life display section 9 does not need to be constructed separately with a liquid crystal display or the like, and an appropriate area of the CRT display 1 can be used. Further, the lifespan information is not limited to the lifespan time, and various information related to the lifespan can be displayed, such as the number of times the power switch 11 is turned on. Furthermore, when the life span has been reached, a notification may be provided with an alarm sound or voice as well as a display.

〔Effect of the invention〕

As described above, according to the present invention, accurate life time information can be easily notified without human intervention, and the usability of a monitor display terminal such as a computer is improved.
