JVC Announces 2nd Generation High-Speed LCD TV Technology

JVC today announced its second generation Clear Motion Drive (CMD) high-speed LCD television technology that delivers crisp fast action images, typically a weakness in LCD performance. JVC’s new Clear Motion Drive II technology, like the original, features a refresh rate of 120 frames per second (120Hz), double the typical rate. But CMD II has been designed specifically for full HD (1920 x 1080) displays and improves motion detection fivefold compared to the original high speed driver.

Three JVC full HD LCD TVs incorporating CMD II will be available in the U.S. this fall as part of a new JVC High Speed 2 series. JVC was the first to introduce high speed LCD technology with its launch last year of a 37-inch set with a 120Hz refresh rate.

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, JVC’s Clear Motion Drive detects 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.
