A digital projector is an electronic device that is capable of connecting to a computer or other device and projecting the video output onto a screen or wall. Digital projectors can be either fixed onto the ceiling, placed on a stand or can even be portable. Digital projectors are used in situations such as office training or presentation sessions, classroom teaching and home cinemas.
There are two types of digital projectors:
- Liquid Crystal Display (LCD) digital projectors
- Digital Light Processing (DLP) digital projectors
Liquid crystal display digital projectors are very popular, as they are lighter and can provide crisp projection. Digital light processing projectors make use of a set of tiny mirrors – one for each pixel of the image – and can provide higher quality images. DLP digital projectors are mostly used in theaters due to their capability of producing high-quality displays. There are many advantages associated with digital projectors. Digital projectors can provide high image resolution as well as ease of brightness and contrast adjustment compared to traditional projectors. Digital projectors can provide sharp pictures and also help in creating smaller, more detailed images.
