ABSTRACT:
A projection apparatus includes a screen to display a picture thereon, an upper cabinet to support the screen, an optical engine provided in a lower portion of the upper cabinet to project an image beam toward the screen, a circuit unit to drive the optical engine, a lower cabinet to accommodate the optical engine and the circuit unit, and a partition plate provided in the lower cabinet to partition the lower cabinet into an upper accommodating portion and a lower accommodating portion to allow the lower cabinet to separately accommodate the optical engine and the circuit unit. In the projection apparatus, the optical engine and the driving circuit are separated from each other, thereby improving a cooling efficiency and a working efficiency, and providing a design having various appearances.
