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)

 

 

Ambient Light Sensor

 

Response

Visible light filtered ~420 to 675nm @ 50% pts.

Field of view

±50 degrees typical to half sensitivity

Dynamic range

0 to 3000 Lux typ.; assumes 18% scene reflectance

 

 

Viewing Angle

(See Figure 10)

 

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.
