2. Common applications of rear projection

At this stage, large screen rear projection TV can be roughly divided into three categories: plasma TV, LCD rear projection TV and DLP rear projection TV. They all have very high definition, especially plasma TV and LCD rear projection TV. However, although the first two products have obvious advantages, they are now subject to cost and manufacturing constraints, and the price is very expensive, which is not affordable for ordinary consumers. Now DLP rear projection TV has obvious advantages over traditional CRT TV, and is much cheaper than the other two products in terms of price. Therefore, for most home users, DLP rear projection TV is the reasonable choice

3. Development history of rear projection

In the development process of rear projection movement, the first generation adopts traditional 50 Hz interlaced scanning technology, while the second generation of high-end movement adopts 50 Hz progressive scanning or 100 Hz interlaced scanning technology. However, 100 Hz interlaced scanning and 50 Hz interlaced scanning are completely homogeneous products, which cannot eliminate large area flicker and interlane flicker at the same time. Changhong "Jingxian King" rear projection was the first in the world to adopt the 60 Hz frequency conversion progressive scanning technology, which is in the leading position in the world. The picture clarity and stability have been significantly improved, and it is called the third generation rear projection color TV.
