Notes:

• Forward Voltage (VF): Typical operating voltage is 3.2V at constant current drive. Ensure the backlight driver circuit can supply stable voltage within the 3.0V ~ 3.4V range.

• Forward Current (IF): Recommended driving current is 100mA (typical). Exceeding this value may reduce LED lifespan or cause overheating.

• Luminance:

  • Without Touch Panel (without TP): Typical brightness reaches 600 cd/m², suitable for high-brightness outdoor or sunlight-readable applications.

  • With Touch Panel (with TP): Typical brightness is 450 cd/m² due to light absorption by the touch panel layer.

• LED Life Time: Rated at ambient temperature of 25±3°C. Typical lifespan is 30,000 hours, with a guaranteed minimum of 20,000 hours under normal operating conditions.
