Test condition
Maximum applied voltage: the maximum voltage that can be
continuously applied to a component in the dark;
Dark resistance: resistance value of 10 seconds after 10Lux
illumination is turned off;
Maximum power consumption: the maximum power consumption when the
ambient temperature is 25℃;
Bright resistance: After 2 hours of irradiation with 400-600Lux,
the test value under 10Lux light of standard light source (color
temperature 2854K);
Gamma value: The logarithm of the ratio of the standard resistance
value at 10Lux and 100Lux.
Lg (R10/R100)
Gamma = =Lg(R10/R100)
Lg (100/10)
R10 and R100 are resistance values of 10Lux and 100Lux illumination
respectively (tolerance of γ is ±0.1)
