TC90240XBG Frame Rate Converter for
100/120 Hz TVs
Description
Current high-definition LCD TV panels
occasionally show motion blur and judder
in some video scenes. To resolve this
problem, LCD TV panel makers are
building panels that refresh at 100/120
Hz instead of the typical 50/60 Hz. This
provides a very sharp picture without the
blur associated with LCD TVs. Toshiba’s
TC90240XBG is designed to take 50/60
Hz input signal, generate additional
frames and output the signal at 100/120
Hz. The device uses LVDS inputs and
outputs to make it very easy to integrate
into an existing LCD TV chassis. In
addition, the TC90240XBG provides de-
juddering to convert content from 24 Hz
to make it appear smooth when
displayed at 100/120 Hz. The
TC90240XBG also offers picture
management functions to improve picture
quality.
