Problems solved by technology

SPDs still switch, but at a much slower rate
[0038] However, electrochromic materials, whose switching states are relatively slow, need to rely on chemical reactions, and take a long time at lower temperatures.
[0039] Therefore, due to these temperature limitations, the use of electrochromic, PDLC and SPD is also limited

Embodiment Construction

[0071] The following terms are used to describe the laminated glass of the present invention. Figure 1A and 1B A cross-sectional view of a typical vehicle laminated glass is shown in . The laminated glass consists of two layers of glass, an outer or outer layer 201 of glass and an inner or inner layer 202 of glass. They are permanently bonded together by a plastic adhesive interlayer 4 . The glass surface located on the exterior of the vehicle is referred to as surface one 101 . The side opposite to the glass outer layer 201 is a surface two 102 . The glass surface located inside the vehicle is referred to as surface four 104 . The side opposite to the glass inner layer 202 is the surface 3 103 . The second surface 102 and the third surface 103 are bonded together by the plastic adhesive interlayer 4 . It is also possible to add a masking layer 6 on the glass. The masking layer typically consists of a black enamel flake printed on one or more of surface two 102 or surfa...

Abstract

Functional layers do not have a good performance at lower temperatures. This limitation is overcoming by combining the functional layers with a resistive heating circuit. The heating circuit uses minimal power to maintain the glazing at or above the temperature required for acceptable operation.

Description

technical field [0001] The present application relates to the field of vehicle laminated glass. Background technique [0002] In response to government regulatory requirements to improve vehicle fuel economy, as well as increasing public awareness and demand for energy-saving and environmentally friendly products, vehicle original equipment manufacturers around the world are striving to improve the energy efficiency of vehicles. [0003] To improve energy efficiency, one of the key elements is lightweighting and solar control. Today, traditional and lower-cost materials and processes are gradually being replaced by innovative new materials and processes. These new materials and processes, although sometimes more expensive, are still more widely used than traditional materials and processes due to their lower weight and correspondingly improved fuel efficiency. Some new materials and processes bring more functionality in addition to the lighter weight advantage. Vehicle gl...
