Description

DETAILED DESCRIPTION OF THE INVENTION [Outline] The present invention, in an abnormality display processing method for displaying an abnormal state on a display screen, is displayed on a predetermined portion of the screen which is temporarily stopped by the abnormality detection. After saving the saved screen contents, an abnormal message is displayed for a predetermined time in the saved screen area, and then the saved screen contents are returned to the original screen repeatedly while the abnormality is detected. As a result, the abnormal display is intermittently displayed on an arbitrary screen without providing a specific abnormal display area.

[Industrial application field]

The present invention relates to an abnormality display processing method for intermittently displaying an abnormality on an arbitrary screen.

[Problems to be solved by conventional technology and invention]

Conventionally, in a device using a display screen such as an LCD (liquid crystal), in order to inform the user (user) that an abnormal state has occurred in the device, a predetermined area on the screen, for example, one line at the top is displayed. In other words, it was fixedly secured as a system information display area, and abnormal messages were displayed in this area together with other system areas. In this way, the system information display area is provided and the abnormal message is displayed in this area. Therefore, in a small display device such as an LCD having only a display area for eight lines, the display area is displayed due to the abnormal display. However, there is a problem in that one line is occupied and the display screen area becomes narrow.

Also, there is a method to display an abnormal message on an arbitrary screen when an abnormal state occurs, but in this method, the area displaying the abnormal message is occupied by the abnormal message and is displayed in the area. There was a problem that it was not possible to reexamine the original contents that had been used.

[Means for solving problems]

In order to solve the above-mentioned problems, the present invention saves the screen content displayed in a predetermined part on the screen that is temporarily stopped by the detection of an abnormality, and then saves the abnormality in the saved screen area. The process of displaying the message for a predetermined time and then returning the saved screen contents to the original screen is repeatedly executed while the abnormality is detected.

Means for solving the problems using the configuration of one embodiment of the present invention shown in FIG. 1 will be described.

In FIG. 1, the display screen 1 in the figure displays characters and the like. Area 1-1 in this display screen 1 is an example of an area for displaying an abnormal message.

An area 3-1 in the middle is an example of an area for storing data for displaying an abnormal message, and characters stored in the area 3-1 are displayed in the area 1-1 in the display screen 1. It

The abnormality detecting means 5 is for detecting an abnormality of the device equipped with the display screen 1, for example, an abnormality such as a voltage drop of the battery when the battery is driven.

The screen stop means 6 stops scroll processing and the like so that the contents displayed on the display screen 1 do not move.

The save means 7 saves the contents displayed in an arbitrary area of the display screen 1, for example, the area 1-1.

The abnormal message display means 8 displays an abnormal message in the area 1-1 saved by the save means 7.

The recovering means 9 restores the data temporarily saved by the save means 7 so as to be displayed in the original area 1-1.

The timer 10 displays an abnormal message in the area 1-1 by the abnormal message display means 8 for a predetermined time.

[Action]

When the configuration described with reference to FIG. 1 is adopted and an abnormal state occurs, for example, when the battery voltage drops below a predetermined threshold value, the abnormality detection unit 5 detects the abnormality and the screen stop unit 6 is detected.
To notify. Upon receiving this notification, the screen stop means 6 notifies the control unit 4 to stop the process of newly writing or scrolling the display data in the display screen memory 3. Next, the saving means 7 causes the display data stored in the area 3-1 of the display screen memory 3 to be temporarily saved in another area. After saving, the abnormal message display means 8 displays the abnormal message in the saved area 3-1.
Write in As a result, the drive circuit 2 displays an abnormality message in the area 1-1 of the display screen 1. After displaying this abnormal message for a predetermined time counted by the timer 10, the recovering means 9 causes the save means 7 to
The display data saved by is written into the area 3-1 in the display screen memory 3 in a manner to be returned. As a result, the display content initially displayed in the area 1-1 of the display screen 1 is displayed in a manner to be returned.

By repeatedly executing the above processing while the abnormal state is detected, the abnormal message and the display content originally displayed in an arbitrary area of the display screen 1, for example, the area 1-1 are displayed. Displayed alternately. Therefore, the abnormal message can be intermittently displayed in an arbitrary area without fixedly setting the specific area as the abnormal message display area.

〔Example〕

Next, the configuration and operation of one embodiment of the present invention shown in FIG. 1 will be described in detail.

In FIG. 1, the display screen 1 is for displaying characters, the area 1-1 is for displaying an abnormal message, the drive circuit 2 is for displaying characters on the display screen 1, and the display screen memory 3 is for displaying. Characters to be displayed on the screen 1 are stored in an expanded form, area 3-1 is an area for storing an abnormal message, and control unit 4 is a display screen in which expanded key input signals to be displayed on the display screen 1 are expanded. A unit for executing and controlling various processes such as writing to the memory 3, a unit for detecting an abnormality by the abnormality detecting unit 5, a unit for temporarily stopping a new writing in the display screen memory 3 for the screen stopping unit 6, and a saving unit. 7 is, for example, the area 3 in the display screen memory 3.
-1 to temporarily save the contents stored therein, the abnormal message display means 8 to write an abnormal message in the area 3-1 in the display screen memory 3, and the recover means 9 to be saved by the save means 7. The written contents are written back in the original area 3-1 and the timer 10 counts the time when the abnormal message is displayed in the area 1-1 of the display screen 1 by the abnormal message display means 8. Is.

Next, the operation of the configuration shown in FIG. 1 will be described in detail with reference to FIGS. 2 and 3.

In FIG. 2, the figure shows a state in which it is detected that an abnormality has occurred. This means that when the voltage of the power supply of the device to which the display screen 1 in FIG. 1 is attached, for example, the voltage of the battery, drops below a predetermined threshold value, it is detected as an abnormal state.

The figure shows a state in which screen processing is stopped. This means that the screen stopping means 6 in FIG. 1 notifies the control unit 4 to stop the process of writing in the display screen memory 3, for example, the scroll process corresponding to the key input signal.

The figure shows a state in which a part of the display is saved.
