| Oki Electric's Display Controllers for Middle/Small LCD TVs Oki Electric Industry has 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 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. 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, PAL, and SECAM - 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 LCDs through I/P 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. write your comments about the article :: © 2006 Computing News :: home page |
