DISPLAY DEVICE, AND METHOD OF CONTROLLING DISPLAY DEVICE
First Claim
1. A display device comprising:
- a connection section to which a plurality of interface boards can be connected in a replaceable manner;
a communication section adapted to communicate with the interface board connected to the connection section;
a determination section adapted to determine a type of the interface board connected to the connection section;
a power control section adapted to control supply of power to the interface board connected to the connection section;
an operation receiving section adapted to receive a selection operation adapted to select any of the interface boards connected to the connection section; and
a display section adapted to display an image based on image information input from the interface board selected by the selection operation to the communication section,wherein in a state in which the power control section supplies the power to a first interface board connected to the connection section but does not supply the power to a second interface board based on the types of the plurality of interface boards determined by the determination section, when the operation receiving section receives the selection operation of selecting the second interface board, the power control section stops supplying the power to the first interface board, and then starts supplying the power to the second interface board after stopping the supply of the power to the first interface board.

Abstract
A projector includes a connection section to which two interface boards can be connected in a replaceable manner, a board communication section, a determination section, a power control section, and an operation receiving section adapted to receive a selection operation of the interface board, and in the state in which the power control section supplies the power to one interface board but does not supply the power to the other interface board, when the selection operation of the other interface board is received, the power control section stops supplying the power to the one interface board, and then starts supplying the power to the other interface board.

5. A method of controlling a display device including a connection section to which a plurality of interface boards can be connected in a replaceable manner, an operation receiving section adapted to receive a selection operation adapted to select any of the interface boards connected to the connection section, and a display section adapted to display an image based on image information input from the interface board selected by the selection operation, the method comprising:
-
determining a type of the interface board connected to the connection section; and stopping supply of power to a first interface board in a case of receiving the selection operation of selecting a second interface board in a state in which the power is supplied to the first interface board connected to the connection section but the power is not supplied to the second interface board based on the types of the plurality of interface boards determined, and then starting supply of the power to the second interface board after stopping the supply of the power to the first interface board.
