Description
The STE2102 is a low power CMOS single-chip TFT controller/driver featuring an extremely low current consumption thanks to an innovative charge pump architecture. Designed to drive a 240 rows by 320RGB columns 262k colors graphic display, with amplitude modulation method, the STE2102 provides all the necessary functions in a single chip, including on-chip gate drivers supply, source drivers supply and source reference voltages generators, resulting in a minimum of externals components.
