A projector is a device that integrates a light source, optics system, electronics and display(s) for the purpose of projecting an image from a computer or video device onto a wall or screen for large image viewing.
LCD TVs are incredibly popular, and prices continue to fall year after year. Yet they're still relatively expensive - you can still expect to pay between $1,000 and $3,000 for many of the high-tech models with large screen sizes.
