DLP vs. LCD Projectors: The Battle of Projection Technology
The age old war between DLP and LCD projectors wages on. But this time, in the 1080p battle, the camps have exchanged strategies.
The Prices, They’ve Dropped.
It was a DLP projector, the Optoma HD80, that was the first 1080p projector to break the price barrier with a low $2,699 street price this summer. At 1300 lumens bright with a 10,000:1 contrast ratio, the 1080p HD80 projector is quite a deal. Epson’s Home Cinema 1080 also came in at $2,699, but after a $300 mail-in rebate.
New “D7″ LCD Technology Improves Contrast and Brightness.
Now, the LCD camp has broken through the contrast ratio ceiling. The new “D7″ 3LCD panels are boosting Epson’s new Home Cinema 1080 UB projector to a record high 50,000:1 contrast ratio. Previous DarkChip3 DLP projectors have topped out at 12,000-15,000:1. Increased contrast ratio improves overall image definition, highlighting details in the clouds of a bright sky or revealing subtle textures hiding in shadows. The new D7 3LCD panels combine higher light output with better pixel alignment to improve image quality.
According to the 3LCD consortium, the new 1080p D7 3LCD chip delivers a 20 percent increase in aperture ratio. This reduces the space between each pixel, allowing more light to pass through it and diminishing what is called the “screen door effect.” The D7 chip also features C2Fine which deepens black levels and provides 12-bit color processing to produce over 68 billion colors. The new 1080p projectors to feature D7 3LCD technology include: Epson Home Cinema 1080 UB, Panasonic PT-AE2000U and the Sanyo PLV-Z2000.
Home Theater Projector Contrast Ratios Rocket Through the Roof
An important note about contrast: Contrast ratios like the record highs touted this fall are only discernable in completely dark rooms. Any bleed of light to hit the screen reduces the contrast of the image. While the projected image does benefit from the improved definition, the brightness, clarity, and color capabilities of the projector are also important factors for typical viewing environments.
New Epson Projector with 50,000:1 Contrast
The forthcoming Epson Home Cinema 1080 UB (for Ultra Black) is native 1920 x 1080 resolution and 1600 lumens bright with a 50,000:1 contrast ratio. The impressive contrast ratio brings startling definition to the image, and its 12-bit color processing brings true, natural color to it. It also features two HDMI 1.3 inputs, lens shift, and a 2.1 optical zoom for flexible home theater setup. The live demonstration was breathtaking because of the realistic depth of field and image detail.
New Panasonic 1080p Projector with 16,000:1 Contrast
Panasonic also built its next generation PT-AE2000U 1080p projector around the new D7 LCD panels. Additionally, it refined its auto-iris technology to provide a consistent 16,000:1 contrast ratio at 1500 lumens of brightness. Panasonic’s iris reads the light level of the video signal frame-by-frame and controls light output for maximum contrast accordingly.

Panasonic also went back to the drawing board for the glass lens design, honing the aspherical curves to best channel the light output. It also features three HDMI inputs this time, with the same 2x optical zoom and lens shift. And, as usual, Panasonic worked with Hollywood film colorists to refine the final color processing to ensure the PT-AE2000U projector produces a natural, film-like image that best matches the original content. Our live demonstration of the new projector featured 1080p Blu-Ray content of a music video. While the content itself was not so inspiring, the projector’s reproduction of it was nothing short of awesome. The colors were rich while refined, and the flesh tones absolutely natural and smooth.
Sanyo Enters 1080p Projector Race
Last but not least (we are going in alphabetical order here), Sanyo enters the true 1080p projector space with their new PLV-Z2000. With the new D7 LCD panels it outputs 1200 ANSI lumens at 15,000:1 contrast, in video mode. This is impressive since many manufacturers quote these ratings from data mode which is inherently brighter. This was Sanyo’s first time on the CEDIA floor and so their booth was small and not without ambient light issues. It was not an ideal demonstration. But with the strength of Sanyo’s engineering for quiet operation, precise color management, 14-bit gamma correction, and two HDM1 1.3 inputs that support the new Deep Color standard, this projector is sure to be a contender. Match that with what looks to be an aggressive price point and it could be the deciding factor in this battle of the DLP and LCD projector war.
Of course the war is not yet over. At Texas Instrument’s DLP booth, a new DarkChip 4 DLP chip was previewed. As part of an HD rear-projection TV with LED (light emitting diode) backlight, it claimed a 100,000:1 contrast ratio. The Dark Chip 4 projector running in their theater listed a 15,000:1 contrast ratio. We can’t wait to see it all next year.
