General Description

The MAX8738 is an I2C-programmable VCOM-adjustment solution for thin-film transistor (TFT) liquid-crystal displays (LCDs). The MAX8738 simplifies the labor-intensive VCOM-adjustment process and replaces mechanical potentiometers, which significantly reduces labor costs, increases reliability, and enables automation.
