  author={Xu Jing-jing and Cai Yan-jin},
The aim of this topic is to design 256×64 dots array LCD module by studying of driver and controller ST7920 which is used with driver ST7921 usually.This module can hold 64 Chinese characters of 16×16 dots in full pallel.Then it can also realize to lighten the light-sized LCD screen by assembly program and the use of MCU. In the concrete,we use controller chip ST7920 which only has driving force of 32 common and 64 segment.So to extend driving force of segment is need.Here we use driver chip… CONTINUE READING
