How to Operate G121EAN01.1?
To ensure optimal performance and longevity of the G121EAN01.1, proper handling and operation are essential. Follow these key guidelines:
1. Handling and Cleaning: The display surface and front polarizer are fragile. Avoid scratches, pressure, or dropping the module. Clean the screen gently using a soft, lint-free cloth and wipe off any water immediately to prevent discoloration or spots.
2. Electrical and Connector Safety: Always power off the module before connecting or disconnecting the input connector. Avoid twisting, bending, or tilting the signal interface connector during installation. Ground yourself properly to prevent electrostatic discharge (ESD) damage.
3. Mechanical and Environmental Considerations: Do not open, modify, or apply direct force to the module, including the reflector sheet and LED light bar. Extreme temperatures can affect brightness, response time, and lamp performance. Continuous operation at low temperatures may reduce luminance and accelerate lamp aging.
4. Usage Recommendations: Avoid displaying static images for prolonged periods to prevent image retention. Use screen savers or periodically refresh content when fixed patterns are shown. Ensure the module is mounted in landscape orientation for specifications to apply accurately.
