摘要： The present invention provides a display apparatus and its cooling method in which optical assemblies can be prevented from being smudged by dusts entered into the apparatus so that an excellent image can be obtained and the heat generated in the apparatus can be cooled sufficiently.
A display apparatus comprises a housing having a screen on its front surface and a closed structure, an optical block having a closed structure and a coupling means for coupling the housing and the optical block in a closed fashion to circulate the air.
Further, a display apparatus comprises a housing having a screen on its front surface and a closed structure, an optical block having a closed structure, a light source, first cooling means for cooling the light source and a second cooling means for cooling the optical block.
As a method of cooling the display apparatus, at least the optical block is arranged to have a closed structure and the optical block is cooled by circulation of the air.
Further, as a method of cooling the display apparatus, the light source is cooled by the first cooling means and the optical block is cooled by the second cooling means.
