MTBF Demonstration 40,000 hours with confidence level 90% Note 1 Note 3
Note1:
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.
Note2:
Evaluation should be tested after storage at room temperature for one hour.
Note 3
: The MTBF (exclude the CCFL ) calculation is based on the assumption that the failure rate
distribution meets the Exponential Model.
