Abstract
A display device includes a power key, and at least one processor that executes following: determination processing that determines, when turning on a light source in response to a user's operation on the power key, whether a power supply supplying power is a predetermined power supply or not, and control processing that displays, when the determination processing determines that the power supply is the predetermined power supply, a power-on continuation confirmation screen and continues, in case of detection of a confirmation operation from the user according to the power-on continuation confirmation screen, lighting of the light source.
Claims14
A display device comprising:
- a power key;
- and
- at least one processor that is configured to:
- detect a user operation of the power key in a state in which a light source is not turned on;
- turn on the light source in response to detecting the user operation of the power key;
- after turning on the light source and in response to detecting the user operation of the power key, determine whether a power supply supplying power is a battery power supply or an external commercial power supply;
- display, in response to detecting the user operation of the power key and in response to a determination that the power supply supplying power is the battery power supply, a power-on continuation confirmation screen to prompt a user to enter a confirmation operation to continue lighting the light source;
- detect whether a user enters the confirmation operation to continue lighting the light source;
- and
- continue, in response to detecting the confirmation operation from the user, lighting of the light source,
- wherein the at least one processor is further configured to, in response to a determination that the power supply supplying power is the external commercial power supply, skip the display of the power-on continuation confirmation screen and continue the lighting of the light source.
A control method of a display device including a power key and at least one processor, the method being executed by the at least one processor, and the method comprising:
- detecting a user operation of the power key in a state in which a light source is not turned on;
- turning on the light source in response to detecting the user operation of the power key;
- after turning on the light source and in response to detecting the user operation of the power key, determining whether a power supply supplying power is a battery power supply or an external commercial power supply;
- displaying, in response to detecting the user operation of the power key and in response to a determination that the power supply supplying power is the battery power supply, a power-on continuation confirmation screen to prompt a user to enter a confirmation operation to continue lighting the light source;
- detecting whether a user enters the confirmation operation to continue lighting the light source;
- and
- continuing, in response to detecting the confirmation operation from the user, lighting of the light source,
- wherein the method further comprises skipping the displaying of the power-on continuation confirmation screen and continuing the lighting of the light source, in response to a determination that the power supply supplying power is the external commercial power supply.
A non-transitory recording medium recording a program readable by at least one processor of a display device including a light source and a power key, the program being executable to control the at least one processor to execute processes comprising:
- detecting a user operation of the power key in a state in which the light source is not turned on;
- turning on the light source in response to detecting the user operation of the power key;
- after turning on the light source and in response to detecting the user operation of the power key, determining whether a power supply supplying power is a battery power supply or an external commercial power supply;
- displaying, in response to detecting the user operation of the power key and in response to a determination that the power supply supplying power is the battery power supply, a power-on continuation confirmation screen to prompt a user to enter a confirmation operation to continue lighting the light source;
- detecting whether a user enters the confirmation operation to continue lighting the light source;
- and
- continuing, in response to detecting the confirmation operation from the user, lighting of the light source,
- wherein the processes further comprise skipping the displaying of the power-on continuation confirmation screen and continuing the lighting of the light source, in response to a determination that the power supply supplying power is the external commercial power supply.
