Table 4. Optical Characteristics.
Luminance
Typical | 1000 NITs at screen center, initial |
Minimum | 900 NITs at screen center, initial |
|
|
Contrast Ratio |
|
Dark room ambient | 200: 1 typical, 150:1 minimum |
500 Lux ambient | 150:1 typical |
3K Lux ambient | 50:1 typical |
100K Lux ambient | 3:1 typical |
Color Coordinates |
|
White field | x = .339 typical |
| y = .353 typical |
|
|
Luminance |
|
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 |
|
Horizontal | ±70 degrees typ., White/black CR ≥ 5 |
Vertical | |

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.
UsageBacklight 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 |
