LCD-Modules already contains an IC - the LCD-Driver - to display the data.
There are different types of LCD-Drivers:
- Chip On Board (COB): The driver is placed on the LCD-PCB and is potted. It is mostly used at Character-Displays. One ore more Driver-ICs are placed at one Module. At dot-matrix LCD-Modules, it willl be replaced mostly with COG.
- Chip On Glass (COG): Flip Chip at ITO-Glass. Voltage generation and different interfaces like 8-Bit parallel, 4-wire/3-wire serial or I2C-Interface are often integrated. Few extrenal components are needed.
