HP 47 inch MediaSmart 1080p LCD HDTV "Out of the box" digital media platform. Enjoy videos, pictures and music from home network + digital media delivered over your broadband Internet connection + 3 x HDMI

Sony are doing well with their consumer television business. According to a January 17, 2007 press release posted on the company website, Sony is a the most popular TV brand in the USA. With its Bravia LCD flat panel television and Grand WEGA rear projection microdisplays, Sony Electronics achieved number one total TV market share in the United States in dollars and units for 2006 (Jan to Nov).

Sony’s KDS-50A2020 Full HD RPTV has a native resolution of 1080p (1920 x 1080). It incorporates Sony’s SXRD microdisplay technology as well as its video signal processing WEGA Engine. The KDS-50A2020 has an impressive contrast ratio of up to 10,000 and a blistering 2.5ms response time. Sound quality has not been ignored as they come with SRS TruSurround XT audio enhancement technology.

Technology Features

Sony’s SXRD Microdisplay Technology

Sony’s SXRD (Silicon X-tal Reflective Display) could be considered as an evolutionary development of LCoS (Liquid Crystal On Silicon) technology. Among Sony’s LCoS competitors are Syntax-Brillian (Gen II LCoS), JVC (D-ILA - Digital Direct Drive Image Light Amplifier) and newcomer MicroDisplay Corporation.

MicroDisplay, a new HDTV manufacturer, received a “Best Buzz” award from Insight Media for its Liquid Fidelity single-chip LCOS technology, demonstrated at this year’s Consumer Electronics Show. According to Insight Media, MicroDisplay received the award this year by offering what they believe to be “the best and only single-chip LCOS powered set available today”. MicroDisplay produce a 1080p RPTV with one LCOS instead of three panels (eg. Sony and JVC). When MicroDisplay begins manufacturing large rear projection TVs for its first OEM brand partners, Memorex and Akai, the reduced complexity of a single LCoS panel should give it a cost advantage.

LCoS, the predecessor technology, is a combination of both the reflective approach of DLP (millions of actuated micro-mirrors on a chip reflect light required for the display) and the transmissive approach of LCD (millions of liquid crystals act as valves passing through light required for the display). In LCoS, liquid crystals are applied to a reflective mirror substrate with the polarization of liquid crystals being used for light transmission control and the mirror below reflecting the light or not as required for image display. LCOS microdisplays are mostly of a three-chip configuration for the three primary colors. As with DLP microdisplays, LCoS relies on projecting the three primary colors rapidly enough so that the eye combines them into a single color.

Sony’s SXRD technology differs from LCoS competitors in that the liquid crystal cell gap measures less than 2um which is far thinner than conventional high temperature Poly-Silicon liquid crystal or LCOS(Liquid Crystal On Silicon) microdisplay devices. Additionally, the TN (Twisted Nematic) liquid crystal, commonly used in projection devices, is replaced by Sony’s unique “Vertically Aligned Liquid Crystal” material where liquid crystals molecules are aligned vertically to the cell substrate. This is a significant technology development overcoming a long-standing challenge. It will improve alignment layer durability and ensure longevity of the high resolution.

NuVision is a relatively new arrival on the wide screen high definition manufacturing scene. It has recently released two 16:9, 1080p (1920 x 1080 pixel resolution) high definition LCD TVs to add to its existing LCD range. An example of NuVision’s emphasis on pushing technological boundaries is its newly released, and reviewed, 1080p LED DLP rear projection TV, the 52 inch 52LEDLP, which utilizes Luminus’s PhlatLight LED chipset to replace the conventional color wheel and lamp assembly used by DLP systems.

In regard to the 42 inch 42LCM1 1080p LCD TV, NuVision have produced an LCD with impressive brightness, contrast and response time. So how do they compare with similar size LCD televisions from more well known brands?

The Sharp DT-500 DLP projector is part of Sharp’s High Definition Home Theatre Projector series and has a native resolution of 1280 x 768 (WXGA) provided by a DarkChip 2 DLP chip by Texas Instruments.

The DT-500’s brightness level of 1200 ANSI lumens is the highest in Sharp’s high definition home theatre projector range and more than suitable for its intended home theatre application. At 1200 lumens a moderate amount of ambient light is tolerable while still projecting a suitably bright projected image. The 4,000:1 contrast ratio is excellent.

Texas Instruments DarkChip 2 DMD Microdisplay Chipset

The Sharp DT-500 projector is based on microdisplay technology having a single Texas Instruments DarkChip 2 DLP chip. The chip has millions of tiny mirrors that switch on and off some 15,000 times per second to create the video output required. This sort of speed is required for delivering sharp pictures for sport and other fast movement video.

One of the features obtained with using the DarkChip 2 DMD is BrilliantColor which is a Texas Instruments trademarked technology for delivering improved brightness and a wider range of colors. Traditionally, most display devices render images using a combination of the three primary colors red, green and blue. The full gamut of colors visible to the human eye cannot be reproduced using this approach, with the color space subset covered not including vivid colors such as yellow and cyan commonly seen in nature. By processing up to six color channels BrilliantColor allows vendors, such as Sharp, to create multi-primary color systems by adding colors such as yellow, cyan and magenta colors for color rendering. As well as increasing the color space which can be rendered with the added color filters the system also utilizes the light source more efficiently with a 50% increase of 50% brightness. In the case of the XV-Z3000, Sharp are using a 6-segment color wheel capable of x5 speed. The higher speed and large number of segments greatly reduces the possibility of viewers noticing any rainbow effects associated with single chip/color wheel DLP projection systems. (read more..)
