They then pass into 3 separate liquid crystal prisms in order to converge the colors to form an image. Liquid Crystal Display (LCD) projectors use non-micro mirrors in order to split projected light into 3 primary colors of red, green, and blue. What’s the Difference between a DLP Projector and an LCD Projector? It requires more lumens than LCD to deal with ambient light.At full power it produces weaker yellows and reds.Rainbow effect or rainbow-colored afterimages.The device has more moving parts than LCDs.Film-like quality on HD videos (since it’s the tech used for modern cinemas).The pixels are less visible compared to LCDs.Available as portable handheld projectors.Let’s now discuss the pros and cons of a DLP projector. What are the Pros and Cons of a DLP Projector? Larry Hornbeck from Texas Instruments originally developed the DLP projector back in 1987.Įven though DLP was invented by Texas Instruments, the first DLP-based projector was instead developed by Digital Projection Ltd back in 1997 a full decade later. What is the History of DLP Projectors?ĭLP is essentially a set of chipsets that use a digital micro-mirror device to work and is based on optical micro-electro-mechanical technology. They coordinate with the light source in order to reflect and render digital imagery to any surface, specifically on projection screens. DLP Projector Buying GuideĪ single-chip DLP comes with a reflective surface with thousands of tiny mirrors. Every 1/50 or a fraction of a second, the retina combines the RGB light to see the full image. This technique is topnotch enough to deliver cinematic quality.ĭLP understands how the human eye works, after all. Thanks to persistence of vision, the blinking colors appear as one colored image to your naked eye. This wheel spins RGB patterns in front of the lamp at high speeds. Single-chip DLPs use the color wheel to create color. How a DLP Projector Works in Terms of Color Some parts partially reflect light in order to create gradients or shades of grey in between the brightness and the shadows. This prevents the light from going to the screen, creating the black levels. In the “Off” position, mirrors reflect light away. When on the position of “On”, the mirror reflects light towards the screen, which creates a visible pixel. It uses thousands of tiny mirrors coordinate by a powerful computer chipset in order to change and shift light reflection in accordance to the data provided by the digital video it’s attempting to render into a sharp, blur-free image.Įvery micro-mirror on the DLP projector creates an image in response to the data of the digital video. Incidentally, most digital cinema projectors nowadays use DLP tech. Just what is the DLP projector? What are the things you should consider before buying this projector type? What are DLP Projectors?Ī DLP (Digital Light Processing) projector is the projector that uses digital micro-mirror technology in order to display digital movies and TV shows on the big screen or widescreen. It might be confusing for some to deal with, but let’s take a step back and cover the most available of the projector types-the DLP projector. 3LCD Projector Technology: Which Is Better? Manufacturers range from BenQ and Optoma to Canon and Sony (and everything in between). There are also different models of projectors on top of the projector types. There are many types of projectors out there.
