What is a "rear-projection television"?
A rear-projection television is a type of TV that uses a large screen and a projection system to display images. Inside the TV, a light source projects images onto a mirror, which then reflects the image onto the screen from behind. This technology allowed for larger screen sizes compared to traditional cathode-ray tube (CRT) TVs, making it popular in the past for home entertainment. However, rear-projection TVs are bulky, require more space, and have largely been replaced by flat-panel technologies like LCD, LED, and OLED, which are thinner and more energy-efficient.
Example
The rear-projection TV was bulky, so we had to rearrange the furniture to fit it properly.
We had to adjust the viewing angle on the rear-projection television to get the best picture quality.
Rear-projection TVs were popular in the early 2000s, but now most people prefer slim LED screens.
