Abstract

PURPOSE:To reduce further the deterioration of a display device due to the screen display of a fixed pattern by turning off the power supply of the display device power supply control part when a human body detecting device detects that no person is in front of terminal equipment. CONSTITUTION:It is set by a time-out setting part 1 how many seconds after the last key input the power supply of the display device is to be turned off, and it is detected by an event generation detecting part 2 whether input from a keyboard or a plotting request or time-out are being generated or not. If an event is generated, it is decided by a time-out detecting part 3 whether or not the event is the time-out, and if the event is the time-out, the power supply of the display device is turned off by the display device power supply control part 5. If it is not the time-out, an event processing part 4 processes the generated event. Besides, even if the event is not generated when the human body detecting device detects the absence of the person in front of the terminal equipment, the power supply of the display device is turned off by the control part 5. Thus, the deterioration of the display device due to the screen display of the fixed pattern can be reduced further.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a computer terminal device.

[Prior art] Fig. 2 shows two examples of rX WTNDOW 5YST.
EM-CLibrary and Protco
l Reference (Digital Pres.
This is a flowchart of a conventional screen saver that was created based on the description of 9, published in 1988). In the figure, (1) is the timeout detection section.

(2) is an event occurrence (manual input from the keyboard, drawing request, or timeout) detection section, (3) is a timeout detection section, (4) is an event processing section, and (5) is a display device power control section.

Next, the flowchart shown in FIG. 2 will be explained.

The timeout setting section (1) sets the number of seconds after the last keystroke to turn off the display device, and the event detection section (2) detects whether input from the keyboard, drawing request, or timeout has occurred. To detect. When an event occurs, a timeout detection unit (3) determines whether the event is a timeout, and if it is a timeout, a 7 display device power control unit (5) turns off the power to the 9 display devices. If there is no timeout, the event processing unit (4) processes the event that has occurred.

The function of the conventional screen saver is realized in this way, and prevents the display device from deteriorating due to displaying one fixed pattern on the screen.

[Problem to be solved by the invention] Since the screen saver is configured like the functional heart of a conventional terminal device screen saver, it is possible to stop displaying on the display device for a certain period of time even if no one is looking at the display device. The issue that needed to be resolved was that it should not be used.

This invention was made to solve the above-mentioned problems, and an object of the present invention is to provide a terminal device that can immediately turn off the power of the display device when no one is present in front of the terminal device.

"Means for Solving the Invention" A terminal device according to the present invention includes a human body detection device that detects whether or not there is a person in front of the terminal device, and a human body detection device that detects whether or not there is a person in front of the terminal device. and a display device power control section that turns off the power of the display device of the terminal device when the display device is detected.

[Function] The terminal device according to the present invention immediately turns off the power of the display device as soon as there is no one in front of the terminal device.
Deterioration of the display device due to displaying a fixed pattern on the screen can be further prevented.

1 Examples of the invention] An embodiment of this invention will be described below.

FIG. 1 is a flowchart of a screen saver according to the present invention. In this example.

(1) is a timeout setting section, (2) is an event occurrence detection section, (3) is a timeout judgment section, (4) is an event processing section, (5) is a display device power control section, and (6) is a human body detection device. It is.

Next, the flowchart indicated by the first [Z+] will be explained.

The timeout setting section (1) sets the number of seconds after the last keystroke to turn off the display device, and the event detection section (2) detects whether input from the keyboard, drawing request, or timeout has occurred. To detect. When an event occurs, a timeout detection section (3) determines whether the event is a timeout, and if it is a timeout, a one display device power control section (5) turns off the power of one display device. If there is no timeout, the event processing unit (4) processes the event that has occurred. Even if no event has occurred, when the human body detection device (6) detects that there is no person in front of the terminal device, the display device power control section (5) turns off the power to the display device.

[Effects of the Invention] As described above, according to the present invention, when it is detected that there is no person in front of the human body detection device or the terminal device, the display device power control section turns off the power of the display device. This has the effect of further reducing the deterioration of the display device due to the screen display of the pattern.
