The STVM100 is a programmable VCOM adjustment solution for thin-film transistor (TFT) liquidcrystal displays (LCDs) to remove "flickers". It can replace a mechanical potentiometer, so that the factory operator can physically view the front screen when performing the VCOM adjustment. This significantly reduces labor costs, increases reliability, and enables automation. STVM100 provides a digital I2C interface to control the sink current output (IOUT). This output drives an external resistive voltage divider, which can then be applied to an external VCOM buffer. Three external resistors R1, R2, and RSET determine the highest and lowest value of the VCOM. An increase in the output sink current will lower the voltage on the external divider so that the VCOM can be adjusted by 128 steps within this range. Once the desired VCOM setting is achieved, it can be stored in the internal EEPROM that will be automatically recalled during each power-up. STVM100 is available in an 8-pin, 3mm x 3mm TDFN8 or 3mm x 3mm TSSOP8 package.
