JVC’s New Clear Motion Drive II technology
June 21, 2007
Some JVC LCD TVs which feature full HD resolution will incorporate CMD II technology. JVC becomes the JVC was the first LCD maker to introduce high speed LCD technology with its launch last year of a 37-inch set with a 120Hz refresh rate.
JVC’s CMD II uses a frame doubling driver (120Hz) and motion interpolation to minimize blurring of moving images, 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 technique prevents moving images from blurring or flickering. By contrast to other frame doubling technologies, using an interpolated frame provides image brightness.
CMD technology was originally applied to a 720p LCD panel and detected only horizontal motion. With the arrival of the new full HD incarnation, JVC’s Clear Motion Drive is able to detect 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.
To get the optimum performance of the double-speed full HD panels, JVC uses its fifth generation D.I.S.T. (Digital Image Scaling Technology) engine. As a result, the images will have more natural shades of grey compared to other panels. JVC’s 10-bit panel renders more than one billion colors for rich, natural color reproduction. Also, with a 10-bit panel the reproducible color gamut is 102 percent based on the NTSC standard, displaying full edge-to-edge color of an NTSC picture. And finally, the single-chip processing ensures superior detection, analysis and control of the signal in real time.
