PNX5120EH
a) General Description
The PNX5120EH is an advanced video picture improvement IC and the world's first solution,
NXP’s Motion Accurate Picture Processing (MAPP), to combine movie judder cancellation,
motion sharpness and vivid color management in a single device. Aimed primarily at digital
and hybrid flat panel televisions in the mid-end and high-end European,Asian and U.S.
consumer markets, it complies with relevant industry standards.LCD TVs represent a huge
and growing market, and the PNX5120EH offers manufacturers a unique combination of
richer color, dynamic motion, sensational sharpness, deep contrast, and full HD resolution.
Moreover, you can easily tailor that balance via the Automatic Picture Control tool (delivered
by NXP as part of a separate System Design-in Toolkit) to meet your own image quality
requirements.
