LCD and DLP are known to be two of the major ways that can be used in order to project different items. DLP stands for Digital Light Processing. This has a chip that comes with many microscopic mirrors and it also has a color wheel. These things will make sure that images will be available on the screen.
LCD projectors will make use of liquid crystal displays that will make sure that the images can be seen very well. The LCD is known to be less expensive as compared to the DLP probably because there are no moving parts that may become affected if in case the way that the projector has been set up is wrong.
