Abstract
The present disclosure discloses a dimming method for a dimming glass, including: in response to a dimming level selected from a user, obtaining a light transmittance value corresponding to the selected dimming level according to a corresponding relationship between dimming levels and actual light transmittance of the dimming glass; obtaining a dimming voltage value corresponding to the light transmittance value according to a corresponding relationship between the actual light transmittance and dimming voltages of the dimming glass; and adjusting a voltage applied to the dimming glass to the obtained dimming voltage value, wherein the corresponding relationship between the dimming levels and the actual light transmittance of the dimming glass is dividing an adjustable range of the actual light transmittance of the dimming glass to obtain the actual light transmittance corresponding to different dimming levels. The present disclosure improves dimming effect of dimming glass.
