OM4068H LCD driver for low multiplex rates
The OM4068 is a low-power CMOS LCD driver, designed to drive Liquid Crystal Displays (LCDs) with low multiplex rates. It generates the drive signals for any static or multiplexed LCD containing up to three backplanes and up to 32 segment lines and can be easily cascaded for larger LCD applications. All necessary functions for the display are provided in a single chip, including on-chip generation of LCD bias voltages, resulting in a minimum of external components and lower power consumption. A 3-line bus structure enables serial data transfer with most microprocessors/microcontrollers. All inputs are CMOS compatible
