Table 3. The electrochromic display operation using the supercapacitor charged with OPV under ambient lighting.
| Working environment | illuminance (lx) | Tlight (K) |
 (V) |
 (V) |
tch (min) | ΔVsc per ECD update (mV) |
|---|---|---|---|---|---|---|
| Filing, copying, etc. | 300 | 3001 | 1.62 | 0.75 | 61.6 | 15 |
| writing, typing, reading, data processing | 500 | 2885 | 2.06 | 0.85 | 48.8 | 20 |
| Technical writing | 750 | 2849 | 2.41 | 0.85 | 41.8 | 36 |
The light illuminance and temperature levels for different lighting conditions, open circuit voltage (
), maximum voltage to which the supercapacitor was charged (
), charging time (tch) and supercapacitor voltage drop per one display state change operation ΔVsc.
