最主要的是 Native contrast: 15,000:1

自從兩年前 SONY 推出 VW-100 SXRD, VW-50; 接著 JVC 推出 LCoS HD-1 將 DLP 陣營打得陣腳大亂以來
(跟據 AVSForum 最近的投票統計, 高階投影機在 AVSForum 會員的持有率為:


JVC RS1/HD1	134	47.52%
SIM2 C3X serie	11	3.90%
BENQ W9000/W10000	14	4.96%
SIM2 DOMINO 80	5	1.77%
SHARP Z21000/Z20000	14	4.96%
SONY PEARL	49	17.38%
SONY RUBY	26	9.22%
EPSON TW1000	8	2.84%
MARANTZ 1080P	5	1.77%
MITSUBISHI HC5000	16	5.67%

HD1, VW100, VW50 三者大致上(參與投票機種有限, 不過還是可以以比例方式相參考比較)占有 74%,其餘 26% 才由 LCD/LDP 兩大技術的眾多品牌/機種分食). 究其原因不外是 DLP 陣營龍頭, TI 沒辦法像 SONY/JVC 在基礎技術層面(晶片的 Native C/R), 和 D/I 技術上有所突破, 以致於各個投影機製造商也連帶的鬥志渙散. 終於在 DC3 推出三年後, TI 再次宣佈 Native C/R 15,000:1 的 dmd chip, DC4. 或許DLP 製造商又可以再次和 SONY/JVC 較勁。

另外, TI 也將在 CEDIA 展出 LED illumination 的 3x dmd's (DC4), 如果價格上可以和 SONY/JVC 一搏, 或3-chip conversion 可以有所突破的話, DLP 或許可以再來攪和一下市場. 不過由於價格/成本因素, 我個人還是比較看重單晶片 DC4 + LED illumination 在主力市場上的競爭力。

DLP(R) Products Announces New DarkChip(TM) 4

New Chipset to Increase Picture Quality and Contrast Ratios for DLP HDTVs and Projector Products
September 06, 2007: 05:00 AM EST

DENVER, Sept. 6 /PRNewswire/ -- DLP(R) Products from Texas Instruments (TI) today announced the introduction of a new chipset, DarkChip(TM) 4, that furthers the position of DLP as a leader in picture quality and contrast ratio. The new chipset is reported to deliver 30% or more increase in native contrast ratio depending upon the application. All DLP product lines, including DLP HDTVs, DLP 1-chip projectors and DLP 3-chip projectors currently feature products with various chipset iterations of DarkChip technology. The new DarkChip 4 will be available in a number of products in 2008.

"Using our current DLP chipsets, our customers have built some of the most competitive Home Theater products in the market, all with excellent picture quality," said Lars Yoder, vice president, DLP Front Projection Business Unit at TI. "We are proud to introduce the next generation of the DLP chip for future product implementations. It will provide our customers even more flexibility for designing projectors that can meet the needs of a wide range of markets."
The DarkChip 4 process was first developed for the high brightness and contrast picture quality requirements of the digital cinema industry, of which DLP Cinema(R) is the founder and uncontested world leader. The contrast improvements from DarkChip 4 are achieved by advances in mirror design lithography and other proprietary process changes.
DLP uses a streamlined optical system that efficiently reflects light to the screen, resulting in a stunning viewing experience -- crisper whites, ultra-rich blacks and images that "pop" on-screen, making it ideal for unforgettable presentations or movies. DLP-based products are known for their native contrast ratio levels which ultimately sets minimum product contrast ratio level for all scene content. Native contrast ratio also sets the "black level" of the system.
"We are constantly searching and innovating new ways to create simply the best HDTV experience. The better the native contrast performance our mirrors can deliver, the more images will jump of the screen," said Adam Kunzman, DLP HDTV business manager. "This breakthrough, combined with our other innovations, vibrant colors, high resolution, clarity and digital imaging, gives our customers a competitive and unique advantage in the marketplace".
At CEDIA (booth #620) DLP is showing multiple demonstrations, of the capabilities of the new chipset innovation. The DLP DarkChip(TM) 4 Theater features a 3 chip, 1080p DLP projector featuring the new chipset producing trillions of colors combined with a native contrast ratio of 15,000:1. Additionally, there is a demonstration of a DLP HDTV with DarkChip 4 and LED illumination with a native contrast performance beyond 100,000 to 1.
