The relative rate of change Δ T of the light valve transmittance T is used to examine the crush resistance of the light valve.
And the relative change rate of delta T is [ (Ton before compression test Ton-Toff before compression test) - (Ton after compression test Ton-Toff after compression test) ]/(Ton before compression test Ton-Toff before compression test) x 100%, wherein Ton refers to the electrified light transmittance of the light valve, Toff refers to the non-electrified light transmittance of the light valve, and the electric field intensity of Ton before compression test is the same as that of Ton after compression test.
It is clear that a smaller value of the relative rate of change of deltat indicates a better pressure resistance of the light valve.

When no voltage is applied (off state), the light transmittance Toff of the light-adjusting film is 0.5%.

When no voltage is applied (off state), the light transmittance Toff of the light-adjusting film is 0.6%. When a 60 hz 220 v ac (on state) is applied, the total light transmittance Ton of the light-adjusting film is 61.1%.
