The MG1203D series LCD modules are 122 × 32 dot displays with a module size of 68.0 mm × 31.75 mm and various backlight options (EL or LED). The document provides detailed mechanical dimensions, absolute maximum ratings, electrical and optical characteristics, as well as pin‑out and initialization instructions.
Key features include a 5.0 V logic supply (4.75‑5.25 V typical), input voltage range 0‑6 V, viewing angles up to 40°, contrast ratios around 1000, and operating temperature from –20 °C to 70 °C. The datasheet also contains block diagrams, RAM mapping and power supply recommendations for both logic and backlight circuits. This manual is written in Chinese.
