FS-LCD Driver IC Family

This series of driver IC is designed for FS-LCD panel use. FS stands for Field Sequential. FS-LCD uses the same panel process as TN that the panel works with RGB LED switching effect to produce a colorful display. FS-LCD driver targets at the applications which require both color display and low cost, such as games, toys, ELA, weather forecast station… etc.
