For example, if you use the projector to project movies in dark rooms, the brightness range of 1000-1200 lumens is reasonable.Ĭontrast ratio: A parameter that reflects the brightness ratio between an image’s lightest and darkest areas. Currently, there is no standard to assess the brightness of the projector accurately.īrightness depends heavily on the environment and projection space. The projector’s brightness depends on the ambient light density, the screen quality, and the image size. Basically, the higher the ANSI lumens, the brighter the image quality. Projector brightness: Brightness is measured in ANSI lumens.

On the other hand, if you use a projector to make high-tech drawings, digital photos, or Excel spreadsheets that contain heavy-duty detailed images, you need a high-resolution projector like SXGA (1400 × 1050) or UXGA (1600 × 1200). If you use a projector to make simple PowerPoint presentations, display charts, or graphs, just a projector with SVGA (800 × 600) or XGA (1024 × 768) resolution is enough. Resolution: Based on the needs used to select the appropriate resolution. Select the specifications for the projectorĭo you understand and know the specifications of the projector or not? Here are some basic specifications to help you choose a suitable projector. Important criteria when choosing a projector A. As a result, this technology does not usually appear on conventional projector models. LCoS can produce high-resolution images but is often larger in size, heavier in weight, and has a higher selling price than DLP or 3LCD. It reflects the same light as DLP but does not use many microscopic mirrors but is a liquid crystal-like 3LCD. 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.
