![]() Performance is superb, and likewise black levels are incredible with deep blacks and bright whites. There’s a reason videophiles flock to LCoS projectors, and contrast ratio, an important image quality spec, proves why. Usually, price is a bit higher, mostly in the thousands. I’ve got a hulking Sony VPL-VW60 home theatre projector with LCoS technology onboard and, while not nearly as portable as my ZTE Spro2 or BenQ GV1, the VPL-VW60 delivers top-tier image quality with lush color reproduction and gorgeous black levels. The likes of JVC and Sony use proprietary LCoS tech, D-ILA and SXRD respectively. DLP, LCD, and LED projectors are far more portable. The lightest LCoS projectors clock in a but over 10 pounds. There’s extremely high resolution, and SVGA LCoS projectors don’t even exist. Therefore, it’s at once a reflective technology and one which opts for LCDs rather than mirrors. However, an LCoS projector passes light through LCD panels which gets modulated by liquid crystals. At its core, LCoS employs liquid crystal chips that have a reflective backing similar to DLP. LCoS, or liquid crystal on silicon, arrives as a sort of LCD-DLP fusion. ![]() Light-emitting diode (refers to light source, not projection type).My BenQ GV1 and ZTE Spro2 projectors are LED devices, making use of an LED light source and DLP projection technology. However, maintenance of LED projectors minimizes overhead since there’s a filterless design, and long lamp life. Black levels, motion blur, color accuracy, and artifacting depends on the underlying projection source, DLP vs LCD. Like LCD and DLP projectors, these can be incredibly inexpensive or bank account-emptying. As opposed to the 1,000-5,000 hour lamp life of most projectors, LED projectors instead boast upwards of 20,000 hours. But rather than a traditional lamp, LED projectors instead use high efficiency bulbs which substantially increase lamp life. In fact, LED projectors may use DLP or LCD technology. Whereas DLP and LCD projectors refer to projection technology, LED concentrates on light source. LED is a common term in lighting technology, standing for light-emitting diode. This doesn’t affect three-chip DLP projectors, but single-chip DLP projectors might experience artifacting. However, DLP projectors may be plagued with rainbow artifacts where bright objects may give off the appearance of a sort of light trail. Motion blur isn’t a huge issue on most DLP projectors, with crisp, sharp images during fast-motion sequences in action flicks and sports. Likewise, color accuracy, while varying quite a bit by device, oftens shines with DLP projectors. Light output on DLP projectors tends to be robust, and suitable for atmospheres with ambient light such as classrooms and conference rooms. DLP projector are easily the most common, with the vast majority of home theatre projector utilizing DLP technology. Price varies quite a bit, from a couple hundred dollar to ten of thousands. These can be found as single-chip DLP projectors, or three-chip DLP projectors with red, green, and blue DLP chips. There’s typically a physical color wheel, which is a literal spinning wheel full of color filters used to generate sequential colors. DLP Projector and BenefitsĪ DLP, or digital light processing, projector makes use of tiny mirrors which in turn reflect light toward a screen. So, buckle up for a deep dive into the world of digital projection. Then, I’ll offer a comparative analysis of their advantages and limitations, with the key points summarized at the end in an easy-to-reference list. In this article, I’ll explain how each technology works and reveal its maximum capabilities. All of these technologies offer many advantages over film and CRT projectors-smaller size, lower weight, less heat generation, and more efficient energy usage-and each one has its own strengths and weaknesses for different applications. Today, film has been almost completely replaced by digital-video projectors that are based on one of three imaging technologies: LCD, LCoS, and DLP. Many home-theater buffs remember those huge, heavy boxes with the bulging red, green, and blue eyes. Meanwhile, cathode-ray tube-based video projectors were developed in the 1950s using red, green, and blue CRTs to project electronic video images onto a screen. For the first half of their history, they relied exclusively on film to provide moving images that were projected onto a screen, and that technology continued to be used in commercial cinemas until around 2000. Motion-picture projectors have come a long way since their hand-cranked progenitors over a century ago.
