ML86V8208 display controllers

Oki Electric Industry Co. Ltd has launched the ML86V8208, a chip that integrates video signals and conforms to NTSC, PAL and Secam video signals. The product includes a video decoder, scaling functions for small and mid-sized LCDs and various video control functions. The ML86V8208TC will be available in volume from May 2005, and the ML86V8208RTC will be available from August 2006.

According to Oki, "in-vehicle" and portable LCD TVs have used analogue signals to lower cost, but have had difficulty in displaying high-definition images because the resolution is limited to 100,000 pixels. To suit HDTV nowadays, LCD panels include a digital interface and can display 300,000 to 400,000 pixels, and the trend has also been applied to smaller TV monitors. However, it is necessary to have a digital video signal processing controller to display high definition images on such devices. Such controllers are said to have been cumbersome because required multiple chips for the video decoder, scalers and on-screen-display control.

Oki claims that its chip succeeded in integrating all these functions. The product is equipped with a video decoder that aims to enhance tolerance for non-standard video signals. The incoming video signal is converted into pixels suitable for W-VGA and VGA LCDs through interlace-to-progressive converter and scaling. The chip is designed for the small and mid-sized 6-10-inch LCDs.
