Briefly describe two smaller, lower-cost data projectors.
What will be an ideal response?
Student responses will vary, but should be drawn from the following information from the text.
Two types of smaller, lower-cost units are LCD projectors and DLP projectors.
• An LCD projector, which uses liquid crystal display technology, attaches directly to a computer or mobile device and uses its own light source to display the information shown on the computer screen. Because LCD projectors tend to produce lower-quality images, users often prefer DLP projectors for their sharper, brighter images.
• A digital light processing (DLP) projector uses tiny mirrors to reflect light, which produces crisp, bright, colorful images that remain in focus and can be seen clearly, even in a well-lit room. Some newer televisions use DLP instead of LCD or plasma technology.
