LCD module identification

摘要

A circuit and a method for an effective way to customize the display driver software of any type of LCD-display and any type of LCD-driver chip used in an LCD display system is achieved. This is important in a multiple sourcing environment where LCD driver chips and LCD modules from different vendors are used in LCD display systems. This is accomplished through identification and registration of the information relevant for the said software customization by storing said information in an LCD module identification register. A microprocessor controlling the LCD display system is reading this identification register and providing the software customization elements specific to the LCD-driver chip and to the LCD-module during an initialization step of the system.
