Specular and diffuse reflection coefficients for device A and device B. The uncertainty was calculated by taking the average of ten measurements
| Device A | Device B | |
|---|---|---|
| R s | 0.071 ± 0.002 | 0.025 ± 0.001 |
| R d (cd/m2 · lx) | 0.064 ± 0.001 | 0.027 ± 0.001 |
Because device A has higher specular and diffuse reflection coefficients, its display has higher reflectivity, and therefore increased glare
