Color Coordinates

White field

x = .339 typical
y = .353 typical

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.
