Absolute Maximum Ratings
The maximum supply voltage for I/O and VCC is 3.6V. The operating temperature ranges from -20°C to +70°C, while the storage temperature ranges from -30°C to +80°C.

Electrical Characteristics
The typical supply voltage for I/O is 1.8V, and for VCC is 2.8V. The LED forward voltage is typically 3.0V, with an input backlight current of 20mA per LED.

Optical Characteristics
The display has a typical brightness of 380 Cd/m² and a contrast ratio of 1000:1. The response time is 30-35ms, and the viewing angle is 85 degrees in all directions.

Environmental/Reliability Tests
The module undergoes various tests including high and low temperature operation and storage, thermal shock, electrostatic discharge, vibration, and shock tests, following IEC and GB standards.

Precautions for Use
Handle the display carefully to avoid mechanical shock and damage. Avoid applying excessive force to the display surface. Use specified solvents for cleaning and ensure proper grounding to prevent static electricity damage. Store the modules away from direct sunlight and in environments free from harmful gases.
