Abstract

There is disclosed an information display apparatus in which a control apparatus main body for controlling a plasma display apparatus for displaying video can disconnectably be connected to a substrate for outputting video data toward the control apparatus main body via a connector. The substrate includes: a RAM and ROM in which information is stored; a video control unit which uses the information to create the video data; and a CPU for controlling the RAM, ROM, and video control unit, the control apparatus main body includes a power source unit for supplying power to the substrate, and the power source unit is connected to the substrate via the connector.

Claims

1. A video display apparatus comprising:

a display control unit which controls a display apparatus for displaying video; and

a video data creation unit which outputs video data toward the display control unit, the display control unit being connected to the video data creation unit via a connector so that the units can be attached/detached with respect to each other,

wherein the video data creation unit comprises;

a storage device which stores information;

a data creation device which uses the information recorded in the storage device to create the video data; and

a control device which controls the storage device and data creation device,

the display control unit comprises a power supply device which supplies power to the video data creation unit, and

the power supply device is connected to the video data creation unit via the connector,

wherein the display control unit further comprises;

a display apparatus which displays the video; and

a detection device which detects contact or access of a member into a display screen of the display apparatus,

wherein the detection device is connected to the control device via the connector or another connector, and

the control device controls the data creation device so that the video data is created based on the information from the detection device,

wherein the video display apparatus further comprises a receiving unit which receives a signal output from a remote controller and provides a control signal corresponding to the received signal to the display control unit and the video data creation unit,

wherein the control device controls the storage device and data creation device based on at least the control signal,

wherein the display control unit further comprises a display controlling device which controls the display apparatus and the power supply device based on at least the control signal.

2. The video display apparatus according to claim 1, wherein the data creation device creates the video data such that a track of the member is drawn in the display screen in response to the contact or access of the member detected by the detection device.

3. The video display apparatus according to claim 1, wherein a program which defines control processing by the control device is stored in the storage device.

4. The video display apparatus according to claim 1, wherein the display apparatus is a plasma display panel.

5. The video display apparatus according to claim 3,

wherein the program comprises an operating system program and various application programs executed on the operating system program,

wherein the control device controls, when the power is supplied, executing the operating system program and the application program, so that the control device causes the data creation device to create the video data based on the application program.
