12/31/2023 0 Comments Digital projector definition![]() DLP projectors use this color technology to deliver cinema-like quality. The color wheel spins RGB patterns in front of the light source at high speeds. This prevents light from traveling onto the screen. In the “On” position, the mirror reflects light toward the screen, creating a visible pixel. In the “Off” position, mirrors reflect light away from the projection lens. Up to 16 million cycles per second.Įach mirror creates an image in response to video source data. These mirrors ( magnified above) manipulate light to create an image. The mirrors must change position on a microscopic suspension hinge at incredible speeds. Developed by Texas Instruments®, the DLP chip, aka digital micromirror device (DMD), differentiates DLP from LCD projectors.Įach mirror on a DLP chip is about the size of a red blood cell. DLP projectors beam light through a color wheel, reflection mirrors, then finally a lens. What is a DLP Projector?ĭLP stands for Digital Light Processing. If you’d like to check out the full range of ViewSonic projectors, click here. If you’d like to learn more about what DLP projectors are, and the benefits you can achieve through using them, read on. It’s even the number one technology in cinema – used in 85% of all movie theaters. DLP technology is widely used in education, business, and home entertainment. The more pixels, the sharper the image.īy packing millions of mirrors into a tiny space, DLP projectors deliver stunning images. The advantage of using so many mirrors is simple. Browse through the different styles of DLP and LCD projectors to find the one that best suits your needs.Imagine projecting a huge image using millions of tiny, little mirrors. Understand your intended usage and most important requirements to help with your selection process. Remember that both projector types will offer a range of good, bad and mediocre performance. Robust feature sets and options across every price point make projectors an accessible technology upgrade for personal and business environments. They're also typically quieter as projectors go. 3LCD projectors deliver exceptional brightness while using less power in many cases.However, they also require more maintenance and upkeep, particularly with changing out filters and preventing dust buildup. LCD projectors tend to be less expensive.DLP projectors tend to have more mirrors and therefore more pixels to project your desired images and videos in higher definition.DLP projectors provide sharp, high-quality projections with the potential for 3D capability as well.What special features are available and how important are they in making this decision?Ĭonsider these factors to help you decide between a DLP or LCD projector:.Will the projector need to travel for use at other locations?.What level of quality is acceptable for the projector? The price point will likely go up as the quality does.Is this a business or personal purchase? What is the intended use?.What is the budget range for this purchase?.LCD projector, it can be helpful to look at available features, strengths and your intended use for the device.Ĭonsider these key points to help guide your projector buying decision and be sure to read our projector buying guide: ![]() When weighing your options of DLP projector vs. This series of open and closed pixels generates a rainbow effect of colors in the projector's output. Polarized light moves through the panels and opened and closed pixels determine whether light goes through or is blocked. The LCD projector channels light first through a metal-halide lamp and then through a prism or group of dichroic filters (the "liquid crystal") that divide the light into a trio of panels to handle the red, blue and green elements in the display. Liquid Crystal Display (LCD) projectors offer more contemporary options for showing video, still images or digital files and data than its predecessors. A DLP chip is vital in the capture and projection of your media files, and a spinning color wheel shines red, blue and green light to create patterns that translate into the intended images being projected. Comprised of chipsets, DLP itself relies on optical micro-electro-mechanical technology that involves the use of a digital micromirror device, or a myriad of tiny mirrors. ![]() Today, DLP front projectors operate in a standalone manner, typically for education in classrooms and business settings. DLP, or digital light processing technology, came out in 1987. ![]()
