2. Brightness
Procedure | - Full white pattern |
| - Use CL100 to measure brightness values of |
| P1~P9. |
| - Follow the brightness formula to calculate |
| brightness values. |
| ☼ Brightness Formula |
| Avg.(P1~ P9)x1.1m2 |
Criteria | - 900 lumens |
3. Ful On/Full Off Contrast
Procedure | - Full white pattern & full black pattern |
| - Use CL100 to measure brightness values of full |
| white pattern P5 & full black pattern B5 ( see im- |
| age: full white) |
| - Follow Contrast formula to calculate contrast |
| values. |
| ☼ Contrast Formula |
| P5/B5 |
| Note: P5=center of white image |
| B5=center of black image. |
Criteria | - 1400:1 |
4. Uniformity
Procedure | - Full white pattern |
| - Use CL100 to measure brightness values of |
| P1~P9 |
| (see image: full white). |
| - Follow the Uniformity formula to calculate |
| average values. |
| ☼ Uniformity Formula |
| ANSI Uniformity = Avg. (P1, P3, P7, P9) |
| /P5X100% |
Criteria | - 65% |
