Abstract

A display apparatus, including: a nonvolatile display device that retains display of information even after the power is cut, a data receiving device that receives data to be displayed on the nonvolatile display device, a volatile storage device that stores the data received by the data receiving device, a nonvolatile storage device that retains the storage of the data even after the power is cut, a display control device that causes the nonvolatile display device to display the data stored in the volatile storage device, a storage determining device that determines whether to store the data stored in the volatile storage device into the nonvolatile storage device, and a storage control device that causes the nonvolatile storage device to store the data stored in the volatile storage device when the storage determining device determines to store the data into the nonvolatile storage device.

Claims

1. A display apparatus, comprising:

a nonvolatile display device that retains display of information even after the power is cut;

a data receiving device that receives data to be displayed on the nonvolatile display device;

a volatile storage device that stores the data received by the data receiving device;

a nonvolatile storage device that retains the storage of the data even after the power is cut;

a display control device that causes the nonvolatile display device to display the data stored in the volatile storage device;

a storage determining device that determines whether to store the data stored in the volatile storage device into the nonvolatile storage device; and

a storage control device that causes the nonvolatile storage device to store the data stored in the volatile storage device when the storage determining device determines to store the data into the nonvolatile storage device.

2. The display apparatus according to claim 1, further comprising:

a storage instruction information receiving device that receives storage instruction information corresponding to the data; and

a reception determining device that determines whether the storage instruction information receiving device has received the storage instruction information,

wherein, when the reception determining device determines that the storage instruction information has been received, the storage determining device determines whether to store the data stored in the volatile storage device into the nonvolatile storage device, based on the storage instruction information.

3. The display apparatus according to claim 1, further comprising:

a determination criterion setting device that sets a determination criterion as a predetermined criterion for determining whether the data is stored in the nonvolatile storage device,

wherein the storage determining device determines whether to store the data into the nonvolatile storage device, based on the determination criterion set by the determination criterion setting device.

4. The display apparatus according to claim 1, further comprising:

an instructing device that gives an instruction to cause the nonvolatile storage device to store the data received by the data receiving device;

an notification device that makes a notification as to input of an instruction through the instructing device; and

an instruction determining device that determines whether the instructing device gives the instruction after the notification device makes a notification,

wherein, when the instruction determining device determines that the instructing device has instructed the nonvolatile storage device to store the data, the storage control device causes the nonvolatile storage device to store the data stored in the volatile storage device.

5. A data transmitting system, comprising:

a display apparatus comprising;

a nonvolatile display device that retains display of information even after the power is cut;

a data receiving device that receives data to be displayed on the nonvolatile display device;

a volatile data storage device that stores the data received by the data receiving device;

a nonvolatile storage device that retains storage of the data even after the power is cut;

a display control device that causes the nonvolatile display device to display the data stored in the volatile storage device;

a storage determining device that determines whether to store the data stored in the volatile storage device into the nonvolatile storage device;

a storage control device that causes the nonvolatile storage device to store the data stored in the volatile storage device when the storage determining device determines to store the data into the nonvolatile storage device;

a storage instruction information receiving device that receives storage instruction information corresponding to the data; and

a reception determining device that determines whether the storage instruction information receiving device has received the storage instruction information, wherein, when the reception determining device determines that the storage instruction information has been received, the storage determining device determines whether to store the data stored in the volatile storage device into the nonvolatile storage device, based on the storage instruction information; and

a client terminal comprising;

a data transmitting device that transmits data to be displayed on the nonvolatile display device of the display apparatus to the display apparatus;

an input device that inputs storage instruction information as information related with storage of the data to be transmitted by the data transmitting device into the nonvolatile storage device of the display apparatus; and

an input determining device that determines whether the input device has input the storage instruction information,

wherein, when the input determining device determines that the storage instruction information has been input, the data transmitting device relates the storage instruction information with the data and transmits the data to the display apparatus.

6. The data transmitting system according to claim 5,

the client terminal further comprising:

an image data determining device that determines whether the data to be transmitted by the data transmitting device includes first image data and second image data that is image data obtained by enlarging the first image data; and

a storage instruction information determining device that determines whether the storage instruction information input by the input device indicates that the data is not allowed to be stored into the nonvolatile storage device,

wherein, when the image data determining device determines that the data includes the first image data and the second image data, and when the storage instruction information determining device determines that the storage instruction information indicates that the data is not allowed to be stored into the nonvolatile storage device, the data transmitting device transmits only the first image data instead of the data.
