摘要： Provided is a projection television TV having a digital micro mirror device (DMD) which includes micro-mirrors to reflect light from a light source according to an ‘on’ or ‘off’ state of the micro mirrors. An illuminating block provides light to the DMD in a uniform optical intensity. A projecting block projects the light reflected from the DMD onto a screen. The projection TV features a projection aperture positioned in the projecting block or the illuminating block arranged perpendicularly to an optical axis. The projection aperture forms an optical path and includes projection areas to pass the light and blocking areas to block the light. The projection area and the blocking area are formed on a cross section of the light with a predetermined space.
