Sanyo EP58B specifications LA7605M

Scan Converter IC for Flat Panel Displays		Video Signal Processor
LC74986NWF	LA7605M

Overview		Overview
The LC75986NWF is a video signal processing IC that performs resolution conversion, IP conversion, and image quality corrections	The LA7605M is a flat panel display color TV signal-processing I2C bus controller IC that supports all the broadcast standards used
without requiring external memory. It can convert and display a wide variety of video signal formats for display on a flat panel	worldwide.
display. In particular, its image quality correction function adjusts the image quality to be optimal for display on a flat panel.
Its OSD function can display characters with a size optimal for the panel used. A video signal processing system for flat panel		Functions and Features
displays can be implemented easily by combining this IC with video converter, A/D converter, and microcontroller ICs and an
LCD panel.		VIF/SIF bloc
