Amazing Action — 100Hz Clear Motion Drive

Excitement and energy will fill your living room just as if you're in a stadium as JVC's exclusive 100Hz Clear Motion Drive feature using original interpolation technology and the MPRT method to evaluate response speed work together to significantly reduce blurring and ghosting on images for much more comfortable and natural viewing enjoyment. The driver has also been improved fivefold to complement the high specifications of Full HD panels equipped with the new 100Hz Clear Motion Drive II.

Original interpolation technology and algorithm

JVC's 100Hz Clear Motion Drive uses a high-precision interpolation algorithm, which detects movement in images and increases the frame rate to 100Hz 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 50Hz TV to display a single frame. Through this method, brighter moving images without flickering or blurring can be achieved. This high-speed 100Hz drive is a beneficial technology derived from D.I.S.T. technology perfected over the years.

Response speed and MPRT

Boosting panel response speed is a key element for reducing blurring or ghosting that can appear on images produced by LCD TVs, and competition is fierce within the industry for developing new techniques to improve the native response speed of panels. JVC is again at the forefront of this issue as it quickly recognised that it was more important to improve the panel's hold-time performance rather than just response speed itself, and focused attention on a method called MPRT that measures the rate of image blurring. The method accurately evaluates how the human eye perceives motion-blur when compared to conventional response speed of the panel. As is shown in the graph, the comparative performance between 50Hz and 100Hz drives is noteworthy: the 100Hz driven panel with a native response speed of 8ms achieves a superior MPRT figure compared to the 50Hz driven panel with the native response speed of a theoretical 0ms. In other words, you enjoy far less blurring or ghost images with a 100Hz driven panel.

100Hz Clear Motion Drive II for Full HD Panels

JVC's 100Hz Clear Motion Drive II found on Full HD models detects image data from more than 8000 surrounding dots in a frame to create a pixel and calculate movement in the current frame to the next. This process is performed on all 2.07 megapixels in a frame using a dedicated LSI with an original algorithm and represents a fivefold improvement over the original drive that used interpolation for complex movement in all directions. Moving news tickers or sub-titles on the screen and even scenes with very rapid panning that include diagonal movement will be reproduced clearly without significant loss in overall brightness and detail. Additionally, 10-bit quantisation process allows the use of 1 billion colours for rich, natural colour reproduction.
