This document introduces the features and characteristics of the LCM160321ZK graphic dot matrix LCD display module produced by Qingyun Innovation. The module has a 160*32 pixel LCD screen, which can display two lines, with each line capable of displaying 10 Chinese characters. It contains 8192 16*16 dot Chinese characters and 128 16*8 half-width alphanumeric characters. In addition, it provides a 64*256 dot drawing area and 4 sets of programmable 16*16 dot matrix character generation functions. The module has a wide power supply range from 2.7V to 5.5V and is designed for low power consumption. It provides three interface modes: parallel 8-bit/4-bit and serial 3-wire/2-wire. The module can display Chinese characters, ASCII codes, and dot matrix graphics, and is widely used in various instruments, household appliances, and information products.
This manual describes the Qingyun LCM160321ZK graphics LCD module, a 160 × 32 pixel display that includes a built‑in character ROM with 8192 Chinese characters and 128 alphanumeric symbols.
