Abstract

The invention discloses a dimming glass assembly, a method for preparing the dimming glass assembly and a vehicle window. The dimming glass assembly comprises a first glass substrate and a second glass substrate which are oppositely arranged, wherein a containing space is formed between the first glass substrate and the second glass substrate; a dye liquid crystal module located in the containingspace and comprising a first substrate, a second substrate and a dye liquid crystal layer, wherein the first substrate and the second substrate are provided with transparent electrodes, and the dye liquid crystal layer is arranged between the first substrate and the second substrate in a clamped mode. The dimming glass assembly satisfies at least one of the following conditions: the transparent electrode is formed of a far-infrared blocking material; an infrared radiation isolation film is arranged on the side, close to the external environment, in the containing space. Therefore, through thetransparent electrode or the infrared radiation isolation film formed by the far infrared blocking material, a good blocking effect on infrared radiation is achieved while the light transmitting effect of the dimming glass is not affected, and therefore the phenomena that glass on the inner side of a car window is overheated and the temperature in a car rises due to sunlight irradiation are effectively reduced.

Description

Technical field [0001] The present invention relates to the field of display, in particular, to a dimming glass assembly, a method and a window of a dimming glass assembly. Background technique [0002] The existing dimming glass window is divided in the summer, due to long-term sun exposure, the inside of the window is significantly increased, up to 65 degrees Celsius, resulting in a passenger in the car feels uncomfortable due to high temperature baking, and When the passengers in the car passes the dimming function of dimming glass through the touch operation, the passenger's hand will also generate a burning sensation due to overheating inside the window, in all, the existing dimming glass window has many in use. Incommunications and defects. [0003] Therefore, the current dimming glass assembly, the method of preparing dimming glass assemblies, and the window of windows remain to be improved. Inventive content [0004] This application is made based on the discovery of the...
