CPT
(5) Judgment standard
10. INVERTER
Inverter Manufacturer ： TBD(SUMIDA 、 FOXCONN..)
*1) Efficiency should be calculated as below formulation：
CPT Confidential
Efficiency*1)
Output Current
Optical efficiency＝output Brightness（nits）/ Input power（watt）
Electrical efficiency＝output power（watt）/ Input power（watt）
Open circuit Voltage
Operating Frequency
Input voltage ripple
[Note] This Inverter design is following ：
Shutdown Time
In-rush current
Input Voltage
Start-up time
The judgment of the above test should be made as follow:
Pass ： Normal display image with no obvious non-uniformity and no line defect.
Partial transformation of the module parts should be ignored.
Fail：No display image, obvious non-uniformity, or line defects.
Duty Ratio
Item
• The degrees of unbalance： ＜10%
• The ratio of wave height：＜√2 ±15%
Electrical
Optical
A：The degrees of unbalance =︱Ip
B：The ratio of wave height = Ip (or I-p) / Irms
