Abstract

The invention discloses heatable laminated glass. The heatable laminated glass comprises an outer glass plate; an inner glass plate; an ink layer; a transparent conductive film at least partially covering the ink layer; at least a pair of bus bars which are arranged on the transparent conducting film and used for providing electric energy for the transparent conducting film; a resin layer arrangedbetween the inner surface of the outer glass plate and the outer surface of the inner glass plate; a conductive array which is arranged between the pair of buses and is in contact with the upper surface of the transparent conductive film on the ink layer; wherein the conductive array comprises a plurality of conductive elements arranged in M rows and N columns, and M and N are integers greater than or equal to 2; the sheet resistance of the conductive element is smaller than the sheet resistance of the transparent conductive film. The heatable laminated glass has the technical effects that the total heating power is not reduced, the process is simple to implement, and the transparent conductive film on the ink layer can provide effective and uniform heat supply for the ink area under thecondition of ensuring no overheating and no overcooling.

Description

technical field [0001] The invention relates to the field of vehicle glass, in particular to a heatable laminated glass. Background technique [0002] The transparent conductive film of coated heating glass is usually located inside the laminated glass. In order to avoid contact between the transparent conductive film and the ink printing surface, reduce process complexity, and improve the conductive stability of the film surface in the ink area, the transparent conductive film is usually deposited on the internal non-printing surface. noodle. For laminated glass with a three-layer structure, the ink printing surface is generally printed on the inner surface of the outer glass plate or the inner surface of the inner glass plate, so the transparent conductive film will be implemented on the outer surface of the inner glass plate, in order to avoid transparent conductive film and printing Surface contact, reduce process complexity, improve the conductive stability of the film...
