Abstract
A windowing device includes: a windowing module including a dimming transparent substrate and a semiconductor temperature adjustment element, the dimming transparent substrate being provided with different light transmittances when the dimming transparent substrate has different adjustment parameters; a temperature adjustment circuitry configured to input a current to the semiconductor temperature adjustment element and adjust a temperature of the semiconductor temperature adjustment element; a temperature sensor configured to detect a temperature of an environment where the windowing module is located; and a controller configured to input a circuitry adjustment signal to the temperature adjustment circuitry when the temperature detected by the temperature sensor is beyond a predetermined temperature range, as to adjust a temperature of the dimming transparent substrate to be within the predetermined temperature range.
