This document introduces the Chinese character library graphic dot matrix LCD display module from Qingyun Innovation, including different models of LCD screen sizes and display capabilities, as well as the functions of the font ROM and GDRAM. The module features low power consumption design and flexible interface interface, and can be widely used in various instruments, household appliances and information products.
The Qingyun Innovation LCMxxZK series are graphic dot‑matrix LCD modules that include a Chinese character ROM (8192 16×16 characters) and a 64×256‑pixel graphics area. They operate from 2.7 V to 5.5 V, consume low power, and support parallel 8‑bit/4‑bit or serial 3‑wire/2‑wire interfaces.
The manual provides product introductions, mechanical dimensions, electrical parameters, pin assignments, hardware interface details, command tables, and example external‑interface applications for various models such as LCM6432ZK, LCM12232ZK, LCM12832ZK, LCM12864ZK, LCM128642ZK, LCM128645ZK and LCM16032ZK. This manual is written in Chinese.
| Screen resolution (LCM6432ZK) | 64 × 32 pixels, 2 lines, 4 Chinese characters per line |
|---|---|
| Screen resolution (LCM12864ZK) | 128 × 64 pixels, 4 lines, 8 Chinese characters per line |
| Operating voltage | 3 V or 5 V (selected by resistor on module) |
| Operating current (no backlight) | 1.2 mA at 3 V, 2 mA at 5 V |
| Backlight voltage/current (LCM6432ZK, yellow‑green) | 4.2 V, 60 mA |
| Supported interfaces | Parallel 8‑bit/4‑bit, Serial 3‑wire/2‑wire |
| Power‑supply range | 2.7 V to 5.5 V |
It supports parallel 8‑bit or 4‑bit mode and serial 3‑wire or 2‑wire mode.
The module can operate from 2.7 V up to 5.5 V.
The /RST pin is active low; pulling it low resets the module.
A yellow‑green LED backlight at 4.2 V, 60 mA is available.
