Hv490fhb-n80 Datasheet Access
Alternatively, an IGBT might have a part number pattern like "FGA" series from Fuji Electric. But the "hv490fhb-n80" doesn't fit that pattern. Maybe an optocoupler with high-voltage isolation.
Optical performance determines the quality of the displayed image. Based on a 1200:1 contrast ratio (Typical) (TM) and a view direction labeled Symmetry, these values are key to evaluating image quality in various lighting conditions: hv490fhb-n80 datasheet
