The Basics: We’re not sure if JVC plans to add any new models to their line of HD-ILA rear-projection televisions, which are based on LCOS technology, so the HD-65S998 and its little brother, the 58-inch HD-58S998, could represent your last chance to get a big-screen JVC RPTV. This 65-inch, 1080p model includes a number of advanced features and technologies, including JVC’s 32-bit Genessa processing chip with Digital Image Scaling Technology and a five-point color management system. The TV uses three native 1080p D-ILA devices and a new optical engine designed to reduce cabinet depth and improve image contrast. The company’s “HD Range 150 MHz Digital Super Detail” is a focusing technology designed minimized motion blur and thus improve detail in faster-moving scenes. This rear-pro has an adjustable iris to lower the light output, and Smart Picture adjusts the image’s brightness based ...

Introduction If you are in the market for a rear-projection TV, chances are you have heard the terms DLP, LCD, SXRD and maybe HD-ILA. DLP’s commercials brag about “millions of tiny mirrors” that produce an HD picture with a spinning color wheel. Although the color wheels in single-chip DLP sets are getting faster and have more segments than they did just a few years ago, I believe the more moving parts that a TV has, the greater the chance for errors, such as the “screen door” and “rainbow” effects, as well as long-term maintenance problems. LCD direct-view TVs are currently the hottest thing on the market, but rear-projection LCD TVs never gained popularity and had a soft picture and weak black levels. Sony’s current rear-projection technology is called SXRD and is a three-chip micro-display technology that uses liquid crystals instead of individual mirrors. JVC has their own “flavor” of this liquid crystal on silicone technology, ...

Introduction When looking for a large TV, the usual suspects that are on the top of most people’s wish lists are plasmas, rear-projection DLPs, rear-projection LCDs and the ever-growing but still very expensive large direct view LCD displays. One technology that is sometimes overlooked is LCOS, which stands for Liquid Crystal On Silicon. Essentially a hybrid of LCD and DLP, LCOS uses liquid crystals that are applied to a reflective mirror; the light is modulated by the liquid crystals as it passes through them. DLP, on the other hand, uses a reflective technology that bounces the light either towards or away from the light by tilting the mirrors. JVC uses a type of LCOS called D-ILA, which stands for Direct-Drive Image Light Amplifier, in their rear projection TVs and stand-alone projectors. D-ILA uses three chips, one for red, one for green and one for blue, unlike DLP’s spinning color wheel. The HD61Z575 is the largest ...
