Micronas GmbH has released the FRC-Q, its fifth generation of motion estimation/compensation (ME/MC) frame-rate converters, rendering the Real Motion experience on Full HD 1080p LCD, PDP and OLED TVs.

LCD displays feature inherent weaknesses of motion-blur and film-judder, with negative impact on the consumers' TV viewing experience. PDP displays have large area flicker, which can be reduced by improving the display frame rate to levels higher than 60Hz. Micronas' truD technology when partnered with the latest generation of high frame-rate displays can give solutions to the issues and gives the audience the ultimate flat-panel TV experience.

More to come
DisplaySearch is anticipating to be released over 13.5 million 100/120Hz LCD TVs in 2008, and is expected to have steady growth in the coming years. The FRC-Q has been created for this rapidly increasing 120Hz FHD flat-panel TV segment, with enhanced picture capacity, more defined details on very fast panning scenes, and improved motion-blur reduction. In a single-chip configuration, the converters generate 120Hz video, and in a two-chip parallel configuration, they give 240Hz video from 50/60Hz video content or 24fps movie sources.

"With the fifth-generation FRC-Q, Micronas is banking on the success of its proven truD Technology," said Johann Weierer, product marketing manager, Micronas. "Our technology increases picture quality at Full HD resolution and gives the perfect solution for 120Hz and 240Hz LCD TVs," he added.

Reduced system costs
Aside from improving video performance, the FRC-Q is expected to reduce system costs. Memory requirements are lowered to a single DDR2 DRAM. It is aimed at substantially lowering power use, drawing away the need for a heat sink, which provides integration into today's ultrathin flat-panel TVs. Finally, it has a compact high-level command interface to quickly connect to a variety of host CPU software architectures.

Micronas' latest frame-rate converter can drive large LCD panels directly. LVDS interfaces on both I/O reduce cost and pin-out and the minimized electrical noise improves signal quality throughout the design. The low-noise behavior is improved by the use of spread-spectrum clocks throughout the IC.

The FRC-Q is providing samples to qualified OEMs presently. Mass production will resume in Q4 08. Micronas will highlight this and other innovative application-specific IC system solutions for consumer electronics in booth 105 at IFA 2008 in Berlin, Germany, from Aug. 29-Sept. 3, 2008
