Luminance Non-uniformity
31% maximum With a white screen, max difference between any 2 of 5
points is defined as follows:
Lnu(%) = (1- (Lmin/Lmax)) x 100%
Luminance Control (typical)
Dimming range 50:1 initial, 100:1 stabilized (Lmax after > 15 minutes
at max. lum., then Lmin at min. lum; dimming range =
Lmax/Lmin)

Safety and EMI
The display will not inhibit the end product from compliance with UL1950, CSA22.2,
and IEC950.The display will not inhibit the end product from complying with FCC Part
15, Subpart J, Class B or EN55022 Class B when housed in a suitable enclosure.
Reliability and Backlight Life
The demonstrated system MTBF is to be greater than 30,000 hours with a 90%
confidence level at 25 °C. Refer to the following table for backlight life.
Table 5. Backlight Life.
Usage Backlight life (typical to 50% of initial luminance)
Continuous at full luminance 20K hours
Continuous at half luminance 100K hours
Typical use using ABC* 35K hours
* Automatic brightness control
