Programmable liquid crystal display module

Abstract

The invention discloses a programmable liquid crystal display module. The programmable liquid crystal display module is characterized by being provided with an independent MCU (Microprogrammed Control Unit) main control module, a special high-capacity Flash memory, an independent LCD (Liquid Crystal Display) backlight driving circuit and an SDRAM (Synchronous Dynamic Random Access Memory) graphic interface video memory, wherein the independent MCU main control module is used for initializing and driving an LCD display screen, receiving, transmitting and processing commands, controlling interface communication, creating, refreshing and alternately displaying interfaces; the special high-capacity Flash memory is used for storing Chinese and English vector character libraries and graphic libraries of vector and bitmap formats. The programmable liquid crystal display module has the beneficial effects that a graphic display driving control unit which is dependent of an application system is provided, and a communication control function with an application system is kept through a reserved interface, so that the programmable liquid crystal display module can be applied to any application system, repeated developing work is avoided, and convenience is brought to use.
