Embodiment Construction

[0041] The following will clearly and completely describe the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0042] Traditional glass generally achieves functions such as shading, heat insulation, and privacy protection through filming. Taking the side window glass of a car as an example, when viewed from the inside of the car, the light transmittance of the side window of the film is about 35% to 50%. In poor light conditions such as night or cloudy days, it is difficult for the driver to see the rearview mirror clearly through the side window with film. If there is no film, there are proble...

Abstract

The invention discloses a dimmable panel, intelligent window glass, a manufacturing method and a control method. In the dimmable panel, through a first driving electrode and a third driving electrode,the light transmittance of a first dimmable area can be independently adjusted; and through a second driving electrode and a fourth driving electrode, the light transmittance of a second dimmable area can be independently adjusted, so that independent partition control over the light transmittance of the first dimmable area and the light transmittance of the second dimmable area can be achieved.A first retaining wall is arranged in the first dimmable area, and the first liquid crystal layer of the first dimmable area is divided into a plurality of first liquid crystal units through the firstretaining wall; and the upper limit value and the lower limit value of the light transmittance of the first dimmable area can be adjusted through the first retaining wall, so that the light transmittance ranges of the first dimmable area and the second dimmable area are different.

Description

technical field [0001] The invention relates to the technical field of liquid crystal devices, and more specifically, to a dimmable panel, smart window glass, a manufacturing method and a control method. Background technique [0002] With the development of science and technology, liquid crystal devices can not only be used in electronic equipment with display functions, but also can be used as dimmable panels, which are widely used in smart window glass. Compared with ordinary glass windows with a fixed light transmittance, the dimmable panels made of liquid crystal devices can adjust the light transmittance based on user needs, and can meet the user's needs for various light transmittance. [0003] At present, dimmable panels are widely used in smart window glass. Compared with traditional glass with fixed light transmittance, smart window glass can adjust the light transmittance by controlling the deflection of liquid crystal molecules to meet the light transmittance requ...
