LCoS (Liquid crystal on silicon) technology is considered a hybrid image technology between DLP and 3LCD. Three important stages of creating an image of 3LCD technology include: creating color from white light beams (red, blue, green), creating images with LCDs, and finally, the combination of creating image and projecting to outside.

One-chip systems are cheap, so they are more commonly used in projectors, while expensive three-chip systems are used in movie theaters.ģLCD Technology (Liquid Crystal Display): Projector technology was born in 1980 by the Epson brand then, about eight years, Epson has granted the rights to use third parties such as Panasonic, Sony, and Sharp. The DLP system has been developed into two types one uses a DLP chip and uses three DLP chips. In addition to electronic components, the DLP system also contains about 2 million microscopic mirrors. Specifically, the projector is divided into three basic types: DLP projector, 3LCD projector, LCOS projector.ĭLP (Digital Light Processing) Technology: The mind is an optical semiconductor chip that was invented in 1987 by Dr.
These technical criteria will be analyzed in detail in the following section. Projector manufacturing technology is judged on the technical standards that affect projector quality, such as brightness, resolution, and contrast. When you want to output images from external sources, these images must undergo some optical conversion combined with the electrons that occur inside the projector, also known as manufacturing technology projectors. – In addition to education, projectors are also widely used in many other fields such as health, military. – Can create a home cinema, serving the needs of watching movies, watching soccer to help connect people. – Become an effective support tool for study and work, bring high efficiency, and save more time. – Easily exchange and transfer information quickly, gradually replacing boring handwritten documents. – Create data presentation slides for presentations in study and work. So what is the real use of projectors in everyday life: The introduction of projectors is a strong affirmation of our human intelligence, thereby contributing an important and positive impact to all humanity’s scientific and technological development.
Compatibility, connection with devicesĪ projector is a digital device or an intermediate processing system used to convert image and video data from peripherals such as PCs, laptops, smartphones into a bright image on any screen that the naked eye can see.
