In a fast changing world, people seldom see a device or equipment that lasts for a long time these days. There are always new inventions, different models, or upgrades cropping up one after the other and as consumers people highly anticipate the faster and better kind than what they already have. Therefore it is quite a surprise that a mini projector (投影仪) is still in use today not only in small scale businesses, schools, or homes but in big corporations and institutions as well. Sure it has a few additional features(特征)here and there but the main function is the same.

  A mini projector today has been fitted with top of the line parts and high quality materials to ensure its efficiency and performance can meet the demands of whoever it is for. It is so designed that it can be used indoors or outdoors with the same functions. The mini projector, as the name suggests, is handy and compact and can easily be brought anywhere by just one person. It can support a broader scope of signals now; USB and card readers are now installed(安装) to cope with the pieces of equipment that people use today to store data.

It can be used at home where it can provide as a form of entertainment or start a conversation during family reunion times. It makes it possible for family members to share with others the photos and videos of one particular vacation, or just to play a series of beautiful landscapes.

Offices also benefit from a mini projector especially during an important meeting or presentation. With at par resolution(标准的分辨率), employees can easily decipher(辨认) the text or data with the use of a mini projector, its bright LED light is sufficient enough to provide a bright and clear image without distortion(变形). Users can now bring this anywhere with them and can be especially useful on a location where the voltage(电压) is unknown.

Perhaps one of the more common places where a mini projector is used constantly is in schools. Teachers or professors use this as an aid to a lesson or discussion to provide better visual aids than usual and to even give their lectures with the use of a mini projector and minimize the use of a board and writing pen. It is often said that children have a very short attention span but they remember things more when things are presented to them visually. This is the perfect use of a mini projector in classrooms where kids easily forget their lesson for the day. Teachers use this to show the class pictures or explanations that tie with the topics for students to remember.
