ABSTRACT:
A projection-type display apparatus and a display method thereof are disclosed, the projection-type display apparatus including a coated portion which is formed on a surface of a substrate, and which scans a video onto a screen, and a patterned portion which is formed on another surface of the substrate in a serrated pattern, wherein the serrated pattern is formed on the substrate according to the surface area of the patterned portion and the depth of the serrated pattern. A serrated pattern is formed on a substrate forming a reflective portion to reflect a video on a screen, so the cooling surface area of the substrate is increased, thereby compensating for distortions in video scanned onto the screen.
