Abstract

This display device includes a display unit, a receiving unit, and a control unit. The display unit displays a first screen having a selection item display area. The receiving unit receives a command for selecting a selection item displayed in the selection item display area. The control unit displays, on the basis of alarm information which indicates that an error has occurred, an alarm mark image in the selection item display area. When the alarm mark image is displayed in the selection item display area, the control unit assigns, to the receiving unit, a function of receiving an alarm mark selection command which is the command for selecting the alarm mark image. When the receiving unit receives the alarm mark selection command, the control unit displays, on the display unit, a second screen for indicating the content of the error.

First claim

displaying an alarm mark image, indicating that an error related to the work machine is occurring, on a display unit of a display device that displays a display related to the work machine; and displaying the alarm mark image in place of a selection item corresponding to a command accepted by an operation unit of the display unit, which is displayed on the display unit together with the alarm mark image.

2 . The control method for the work machine according to claim 1 , wherein the command is changed to another command along with displaying the alarm mark image.

3 . The control method for the work machine according to claim 2 , wherein the another command causes the display unit to display a screen showing contents of the error.

4 . The control method for the work machine according to claim 3 , wherein the command causes another screen to be displayed that differs from a screen showing the contents of the error.

5 . The control method for the work machine according to claim 1 , wherein the selection item is arranged outside of the display unit and facing the operation unit.
