Podcast Episode Transcript

Welcome to the Best Video Projectors Podcast. This is the spot for you to learn about video projectors and video projector technology. Let's get into focus.

Picture this: you're watching a football game. The quarterback drops back, the ball sails across the field. On a DLP projector, that ball might leave a tiny rainbow trail. On an LCD projector, the grass might look a little soft. On an LCoS projector, it looks like you're at the stadium. Same game. Same screen. Three totally different pictures. Why? Because of the chip inside the projector. And most buyers never even think about it.

Focusing on DLP, LCD and LCoS Projector Chips

So today, we're going to open up the hood and look at the three big families of projector brains: DLP, LCD and LCoS. I know, those acronyms sound like alphabet soup. But I promise you, by the time we're done, you'll know exactly how each one creates the image you see, why one might be perfect for your Friday night movies, and why another one is the secret weapon for bright family rooms. And you'll never look at a projector the same way again.

DLP Projectors

Let's start with DLP, which stands for Digital Light Processing. This is the chip inside a ton of projectors, especially the portable ones. Here's how it works: Imagine a chip covered in millions of microscopic mirrors. Each mirror is one pixel. They flip on and off thousands of times per second. To create color, most DLP projectors use a spinning color wheel with red, green, and blue segments. The mirrors bounce light through that wheel, and your brain blends the flashes together into a full-color image. It's fast, it's efficient and it's why so many gaming and portable projectors use DLP. Take the BenQ TH575. It's a DLP projector with around 3,800 lumens, 1080p and a price tag near $550. For a bright living room, that kind of punch is hard to beat.

But DLP has a quirk. Some people see little flashes of red and green in fast motion, especially when something bright moves across a dark background. It's called the rainbow effect, and it's why some people can't watch DLP at all. If you're one of them, you'll know within the first few minutes of a demo. If you're not? You might never notice it.

LCD Projectors

Now, here's the crazy part: the projector next door might be doing the exact same job with three tiny stained-glass windows instead. That's LCD, which stands for Liquid Crystal Display. Instead of mirrors, LCD projectors use three separate liquid crystal panels: one red, one green, one blue. Think of each panel like a stained-glass window. Light shines through all three at the same time, then the projector combines them into a single image. Because the colors are handled simultaneously rather than one after another, LCD projectors can get incredibly bright. Epson's Home Cinema 3800, for example, pumps out around 3,000 lumens, and it often lands around $1,300. For a family room with a few windows, that's a serious advantage.

The tradeoff? LCD panels have tiny gaps between the pixels. On a big screen, especially if you sit close, you can sometimes see a faint grid pattern. It's like looking through a screen door. Some people never notice it. Others can't unsee it. If you're the type who notices, look at a 4K LCD model, because the higher pixel density really helps.

LCoS Projectors

Now we get to the favorite of home theater purists: LCoS, which stands for Liquid Crystal on Silicon. This is the fancy one. Instead of letting light shine through a panel, LCoS reflects light off a silicon backing. The light passes through the liquid crystal layer, hits the silicon and passes through again on the way out. That double pass gives better contrast and color purity. The result is incredibly smooth, with deep blacks and almost no visible pixel structure. Sony calls their version SXRD. JVC calls theirs D-ILA. These are the projectors that make movie lovers go quiet. The Sony VPL-XW5000ES is a laser LCoS projector that can cost around $4,000. But when you're watching a dark scene in a blackout theater, you'll understand why people pay for it.

OK, so if LCoS is so great, why doesn't everyone buy one? The short answer is money. LCoS is more expensive to make, and that cost shows up in the price. It's also usually bigger and heavier because the optical engine is more complex. So if you're looking for a cheap, portable projector to throw in a backpack, LCoS is not it. But if you're building a dedicated home theater and you want the best picture money can buy, LCoS is the only answer.

Which Projector Chip Is Best for Specific Use Cases?

So how do you choose? Let's match the technology to your situation. If you watch sports in a bright room, don't let anyone sell you LCoS. You'll be paying for black levels you can't even see. Go with a bright LCD or DLP model instead. If you're gaming and you want low input lag and easy portability, DLP is your friend. If you're building a blackout basement theater and movies are your obsession, LCoS is the only answer. And if you're on a budget but still want a great all-rounder, a good three-panel LCD projector from Epson or a DLP from BenQ or Optoma will make you happy. Just remember: The best projector isn't the one with the highest number on the box. It's the one that fits your room, your content, and your eyes.

Let's bring it all together. DLP uses a chip full of tiny mirrors and a color wheel. It's fast, efficient and great for gaming and portability. LCD uses three liquid crystal panels. It's bright, sharp and often a better value. LCoS uses reflective silicon to deliver the smoothest, most cinematic image with the deepest blacks. When you're comparing projectors, don't just look at the brightness number or the resolution. Ask what's inside. Ask if it's DLP, LCD or LCoS. That one question will tell you more about the picture quality than almost anything else on the spec sheet.

Questions and Answers

• Why do identical scenes look completely different on DLP, LCD and LCoS projectors?
  Because of the specific chip technology inside the projector that creates the image.

• How does DLP technology create an image?
  It uses a chip covered in millions of microscopic mirrors that flip on and off, bouncing light through a spinning color wheel.

• What is the "rainbow effect" associated with DLP?
  Tiny flashes of red and green seen in fast motion, particularly when bright objects move across a dark background.

• How does LCD technology differ from DLP in processing color?
  LCD uses three separate liquid crystal panels (red, green and blue) and handles colors simultaneously rather than sequentially.

• Why do home theater purists prefer LCoS?
  It reflects light off a silicon backing for a double pass, yielding better contrast, color purity, deep blacks, and no visible pixel structure.

• Why isn't LCoS used by everyone?
  It is more expensive to manufacture, and the units are typically larger and heavier.
