Abstract
An image display apparatus includes a display panel formed by arranging in juxtaposition a face plate carrying thereon a phosphor and a rear plate carrying thereon electron-emitting devices within a housing. The phosphor is so arranged as to be irradiated with electrons emitted from the electron-emitting devices to display images. The image display apparatus further includes an air blower for causing air to flow between the display panel and the housing.
Claims27
An image display apparatus comprising:
- a display panel formed by arranging in juxtaposition a face plate carrying thereon a phosphor and a rear plate carrying thereon electron-emitting devices, said phosphor being so arranged as to be irradiated with electrons emitted from said electron-emitting devices to display images;
- a housing containing said face plate and said rear plate, said housing having a flow path connecting a space in contact with said rear plate with a space in contact with said face plate;
- and
- air blowing means for causing air to flow through said flow path.
An image display apparatus comprising:
- a display panel formed by arranging in juxtaposition a face plate carrying thereon a phosphor and a rear plate carrying thereon electron-emitting devices, said display panel having an outer surface on which a thermally conductive member having a higher thermal conductivity than said face plate and said rear plate is arranged;
- a housing containing said display panel, said display panel being arranged within said housing in such a manner that a space is formed between said rear plate and an inner wall of said housing;
- and
- air blowing means for causing air to flow through said space.
An image display apparatus comprising:
- a display panel formed by arranging in juxtaposition a face plate carrying thereon a phosphor and a rear plate carrying thereon electron-emitting devices;
- a housing containing said display panel, said display panel being arranged within said housing in such a manner that a space is formed between said rear plate and a wall of said housing facing said rear plate, said housing having an opening in a wall of said housing facing said face plate;
- and
- air blowing means for causing air to flow through said space.
