Oki Electric Launches Display Controllers to be used in Middle / Small LCD TVs including In-vehicle Models
Conformed with the three world standards and integrates necessary video signal processing functions onto a single chip
ML86V8208
Tokyo, Japan, March 14, 2006 -- Oki Electric Industry Co., Ltd. (TSE: 6703) today announced the launch of ML86V8208, a chip that integrates all necessary video signals into a single chip and conforms to the three world standards for video signals. This chip includes a video decoder, scaling(*1) functions for small and mid-sized LCDs, and various video control functions, which are integrated into a single chip that helps lower costs for middle and small size LCDs. The standard chip, "ML86V8208TC," will be available in volume from May 2005, and "ML86V8208RTC," a version with in-vehicle quality, will be available from August 2006.
"The in-vehicle application chip will enable high reliability and quality compliant with ISO/TS16949, the quality management system standard for automobiles," said Akira Kamo, President of Silicon Solutions Company at Oki Electric. "Because we have expanded the operating temperature range for the standard chips, they can be used in TVs for kitchens, bathrooms, and even outdoors. We will continue to work on enhancing functions for digital TV broadcasting to contribute to making video media more accessible."
In-vehicle and portable LCD TVs have used analog signals for lower cost, but have had difficulty in displaying high definition images, as the resolution is limited to 100 thousand pixels. Nowadays, to suit high definition TV, LCD panels include a digital interface and can display 300 to 400 thousand pixels, and the trend to hi-definition has also been applied to smaller TV monitors. However, to display high definition images on such devices, it is necessary to have a digital video signal processing controller. However, such controllers have been cumbersome, as they have required multiple chips for video decoder, scalers, and on-screen-display (OSD) control.
Oki's ML86V8208 succeeded in integrating all these functions into a single chip. Conforming to NTSC(*2) , PAL(*3) , and SECAM(*4) -- the world's three TV signal standards, this chip is equipped with a video decoder to enhance tolerance for non-standard video signals, such as when reception of TV signal is weak, or for special VTR playback. The incoming video signal is converted into pixels suitable for W-VGA and VGA(*5) LCDs through I/P (interlace-to-progressive) converter and scaling. Designed with the small and mid-size 6-10-inch LCDs in mind, this chip does not use large memories and thus achieves video processing with excellent cost performance. It is also equipped with on-screen-display function, to display menus, etc.
Glossary
- *1 :Scaling
Converts the input picture resolution into display resolution by expanding and shrinking vertically and horizontally. Scaling is used to even out pixels horizontally or change the scale of central and peripheral screens (panoramic mode).
- *2 :NTSC (National Television Standards Committee)
This is a video signal format used in the U.S., Canada, Korea and Japan, etc. It has a field cycle of 60Hz, 525 lines, and a color sub carrier frequency of 3.58MHz.
- *3 :PAL (Phase Altering Line)
This is a video signal format used in Europe and China, etc. It has a field cycle of 50Hz, 625 lines, and a color sub carrier frequency of 4.43MHz.
- *4 :SECAM (Sequential Couleur AVEC Memoire)
This is a video signal format used in France and Russia, etc. It has a field cycle of 50Hz, 625 lines, and a color sub carrier frequency of 4.40/4.25MHz.
- *5 :W-VGA, VGA
Name of pixels used in LCD panels. W-VGA (Wide VGA) represents of 800 x 480 or 854 x 480 pixels, and VGA of 640 x 480. (The three colors R/G/B included in one pixel)
