Transportation Please refer to Packing instruction Reliability Performance Electrostatic Discharge Requirements This display shall withstand 4kV for contact discharge and 8kV for air discharge of Electrostatic Discharge to meet the acceptance criteria as specified in EN55024. Hinge Life Mean time between failure (MTBF) For the purposes of demonstrating the MTBF of this product, a failure is defined as the inability of the product to function in accordance with this specification. A failure event interrupts the expected operation of the product and requires service or repair to restore the product to full functionality. The MTBF of this product shall be demonstrated to meet or exceed 50,000 hours @ 25 °C at a 90% lower confidence limit under all operating conditions as specified in previous section. ( Lamp life is not included ) All components including power and inverter shall be derate to 80% for active devices, 80% for capacitors and 50% for resistive components, except for polarized capacitors which may be operated at 90% of voltage - which are all calculated under worst case conditions. Mean Time Between Replace ( MTTR ) This display shall be well designed to take less than 5 minutes for replacing control board or inverter board. Note: If there is anything not clarified or specified on this specification, PVT sample shall be a standard reference.
