LCD Module (LCM) Technology

LCMs are an easy way to incorporate an LCD display into a microprocessor controlled product. Modules relieve the burden of designing complex LCD driver circuits. The smarts that come built in with the module take commands from a microprocessor and does the actual work of driving the display. All the user has to do is command the module with digital instructions.

LCD Module Construction Types

Chip On Board (COB) construction is the most common type of LCD module on the market today. This type of module has the LCD glass mounted via a bezel to a printed circuit board (PCB) containing the LCD driver ICs. A 8 bit parallel interface is provided to directly interface to a microprocessor (MPU).
