The current projector has 3 types of technology used:
     • CRT Projector: use cathode ray tube and has 3 color tubes that is blue, green, and red. These 3 color tubes can move to adapt the degree of pictures. This projector is the oldest type and no need much maintenance, but the appearance is not beautiful because the Projector has a large size. The advantage is it can project a picture to make it become a large picture in the lower price.
     • LCD Projector is uncomplicated system, so kame the Projector is widely use because it is low price. This Projector has vision problem called screen door effect or pixilation effect, which we can see pictures as dot, small square, and electric tube is high price. The projection on Projector LCD uses metal halide lamp to shine the light to the prism for spreading the light to 3 color silicon that is red, green, and blue for sending pictures as a video signal. When the light pass through the silicon, each pixel will open or close to provide pictures both the desired color level and gradient. The reason why we use metal halide tube because it can provide the precise temperature of colors and gradient and also give the light in some areas where is small size.
     • DLP Projector: uses Digital Light Processor technology of Texas Instrument that has the smallest light generator called Digital Micromirror Device (DMDs). This Projector works by using 2 DMD and using glass turntable to create color. The problem of this Projector is Rainbow effect that is people see the picture as white color and change to rainbow color. The solution of this problem is to use 3 DMD with the high speed of the plate’s rotation, and can precisely provide the main color.
