Embodiment Construction

[0018] To solve the problem of non-uniform heating in the working area of ​​the non-rectangular transparent conductive film, the present invention proposes a solution, that is, add a forced equipotential line between the positive and negative electrode leads of the film, and the forced equipotential line can be one or several metal wires.

[0019] As a conductive film with a heating function, its basic structure is to be equipped with electrode leads on a group of opposite sides of the film, and the electrode leads are connected to the positive and negative electrodes of the power supply to form a conductive circuit.

[0020] The present invention adds metal wires between positive and negative electrode lead wires. The metal wires are attached to the film by means of mechanical external force, bonding, etc., and the metal wires as equipotential lines should form good electrical contact with the film.

[0021] The principle of adding forced equipotential lines in the present in...

Abstract

The invention discloses a method for improving the heating uniformity of an electric heating film and an electric heating film with uniform heating. A plurality of equipotential lines are added between positive and negative electrode leads of a non-rectangular electric heating film. The equipotential lines can be obtained by Made of a variety of materials, it can be metal wires or strips, or other non-metallic conductive materials. There are one or more equipotential lines, and there is an interval between each equipotential line, and the intervals can be equal or unequal. The invention can effectively reduce the heating inhomogeneity caused by the inhomogeneity of the surface current density caused by the shape by adding the forced equipotential line, and improve the electric heating uniformity of the whole working area. The invention provides a reliable solution for the problem of heating uniformity of the irregular electric heating system for the first time, expands the application field of the thin film electric heating device, and solves the problem of uneven heating of the irregular electric heating system.

Description

technical field [0001] The invention belongs to the technical field of electric heating film and electric heating glass, and relates to a conductive film used on electric heating glass, in particular to a method for improving the heating uniformity of the electric heating film and related products. Background technique [0002] Transparent conductive films are divided into conductive films that can be attached to substrates, conductive coatings, and conductive films grown on substrates using various film growth techniques. The main functional layer of the conductive film is a metal film or a conductive oxide film. Transparent conductive film is a special functional material that combines both transparency and conductivity. Usually attached to transparent substrates such as glass, quartz, crystal, etc. Existing transparent conductive films mainly include metal film series, composite film series and oxide semiconductor films. Utilizing the conductive properties of the film,...
