Projectors are particular devices including a unique type of tech jargon associated with them. Unlike mobile phones or computers, where the technical terms such as RAM, OS, megapixels are generally understood by every other non-technical persons, the language normally used to describe a projector can confuse a teenager too. It sometimes helps us to understand the terms like LCD, DLP, aspect ratio, lumens, contrast ratio etc. if you can understand these terms well, they will help you to make a better purchase further.  The epson vs250 projector review includes all the necessary terms and technical ideas regarding a 3LCD projector that everyone needs to know about.

How will you choose a projector before going to buy one? First, you need to know all the basic types of projectors are available in the market.

  • DLP projectors: Digital Light Processing or DLP projectors were developed in the late 1980’s as a new technology. In today’s world, DLP is one of the leading projection display technology and about 85% of all digital cinema use a DLP projector. The colors in a DLP projector are normally produced by any type of light source such as a lamp that emits light towards the color wheel. This color wheel is consists of numerous microscopic mirrors. The actual number of these mirrors matched up to the pixel resolution of that projector. The high brightness and image quality are the main reason why people prefer DLP projectors.
  • LCD projectors: LCD projectors are the latest updated versions of the previous DLP projectors. They both face quite a tough competition between them. The LCD projectors are now produced by Epson who are using their unique 3LCD technology powered by 3 LCD screens and includes a powerful metal-halide lamp. In general, LCD projectors are quite cheaper and more lightweight compared to the DLP projectors. Due to its portability, these LCD projectors are mainly used in homes and official presentations as well. The epson vs250 projector review states that the 3LCD projector offers high brightness and you will get the extremely high quality of HD images.
  • LCoS projectors: it is a mix between the DLP and LCD technology. LCOS stands for “liquid crystal on silicon”. These types of projectors are expensive choices. Now, these types are participating in the existing market. The technology uses a mixture of crystal and individual mirrors that are supported by a silicone backplane to project the images. Most of the LCOS projectors include an extremely high resolution which is in the SXGA range 1365×1024. This is the reason why these projectors are comparatively more expensive. The initial price starts at around a thousand dollars. So, LCOS devices are not for home or personal uses. Only the large companies can afford to buy an LCOS projector.
