JVC Launches LCD TV Line Featuring 2nd Generation High-Speed Technology
A new line of JVC full HD LCD televisions featuring the company's second generation high-speed LCD technology was announced today. The new flat panel sets feature the company's Clear Motion Drive II technology with a 120 frames per second (120Hz) frame rate, double the typical rate, to deliver crisp fast action images. To further enhance performance, the new line uses 10-bit LCD panels for more accurate color reproduction and more natural grey scaling.
JVC's Clear Motion Drive II 10 bit 120Hz technology will be offered in three new sets – the 37-inch LT-37X898, the 42-inch LT-42X898 and the 47-inch LT-47X898. JVC was the first to introduce high speed LCD technology with the launch of Clear Motion Drive in Japan in 2005. The technology's second generation, Clear Motion Drive II, has been designed specifically for full HD (1920 x 1080) displays and improves motion detection fivefold compared to the original high speed driver.
To reduce blurring of moving images, JVC's CMD II uses a frame doubling driver (120Hz) and motion interpolation. A JVC algorithm detects the movement in images and increases the frame rate to 120Hz to create an interpolated image that is displayed as two frames – the original plus the newly interpolated frame – in the same time it takes a conventional (60Hz) set to display a single frame. This delivers moving images without blurring or flickering. And compared to other frame doubling technologies, inserting an interpolated frame maintains image brightness.
JVC's original CMD technology was applied to a 720p LCD panel and detected only horizontal motion. In its new full HD incarnation and in contrast with most other frame doubling technologies, JVC's Clear Motion Drive is multi-directional, detecting image data from more than 8,000 surrounding dots in a frame to create a pixel and calculate movement from the current frame to the next. This process is performed on all two million pixels (1920 x 1080) in a frame to interpolate for movement in all directions.
An indication of CMD's ability to deliver sharp images is the panel's motion picture response time, or MPRT. Though liquid crystal response time has long been used as a measure of LCD TV performance, JVC considers MPRT, a relatively new measurement gaining wider use, to be a better performance indicator. MPRT measures the rate of image blurring and is based on how the human eye perceives speed. A faster MPRT means less blurring. JVC research shows that for any given liquid crystal response time, the MPRT will be significantly better at 120Hz than at 60Hz. In addition, the improvement is more apparent at lower response times. A 120Hz-driven LCD panel with an eight millisecond liquid crystal response time will achieve an MPRT figure that's superior to what a 60Hz-driven panel with a zero millisecond liquid crystal response time can achieve. As a result, the 120Hz panel will have less blurring of moving images.
To further enhance performance, JVC's CMD II TVs use a 10 bit IPS LCD panel, which renders more than one billion colors for rich, natural color reproduction, provides natural gray scaling and provides 64 times smoother gradation than does an 8 bit panel. To get the most out of the advanced 10 bit 120Hz panel, JVC's high-speed LCDs feature the company's fifth generation D.I.S.T. (Digital Image Scaling Technology) engine on the JVC-exclusive 32-bit Genessa chip, which combines all core image processing circuits together in a single chip that allows for faster communication among circuits. What's more, the panel features IPS (In Plane Switching) technology for a wide 178-degreee viewing angle.
Specifications include a contrast ratio of 2000:1, 4.5msec response rate, 500cd/m2 brightness, and a 178-degree viewing angle.
All three JVC LCD TVs include three HDMI v1.3 inputs, one RS-232 interface, one PC input, one Smart Video input, two component inputs, one S-Video input, three AV inputs, one optical digital audio output and one fixed audio output.
Each set's sound package includes MaxxAudio, a suite of five psychoacoustic DSP technologies that compensate for the limitations of small speakers. The sound package also includes a 20-watt amplifier, JVC's Twin Oblique Cone speakers, Advanced Hyper Surround Plus, and JVC's Smart Sound, which maintains a constant volume level as content changes (such as from program material to commercial).
A universal remote control is included with each set, offering direct selection of five different video inputs.
JVC's new Clear Motion Drive II LCD TVs will be available this month as part of JVC's new Procision series of premium-level products to be sold through a select group of dealers. The 37-inch LT-37X898, the 42-inch LT-42X898 and the 47-inch LT-47X898 will sell for about $2,100, $2,600 and $3,300, respectively.
