Embodiment approach

[0010] Specific implementation methods, such as Figure 5 As shown, add a Z axis:

[0011] (1) For printing of silver or other metal nanoparticles, add the Z axis to the printing drawing design, and the X, Y, and Z are insulated from each other. The X, Y, and Z axes can be straight lines, broken lines, curves, etc.

[0012] (2) Copper wire printing technology, adding Z axis in the design of printing drawings, X, Y, and Z are mutually insulated, and the X, Y, and Z axis wiring can be straight lines, broken lines, curves, etc.

[0013] Within the spirit of the present invention and the protection scope of the claims, any modification and change made to the present invention will fall into the protection scope of the present invention.

[0014] figure 1 is a single touch

[0015] figure 2 Is the effective point of double touch

Abstract

The invention discloses a projection-type capacitive touch film 'ghost point' eliminating method. According to the achievement principle, two points cannot be uniquely determined in X-dimensionality and Y-dimensionality, so that Z-dimensionality is introduced, and the two points are uniquely determined. The projection-type capacitive touch film 'ghost point' eliminating method comprises the steps of integrating with a specific process, namely integrating with a metal nano-particle printing technology and a copper lead printing technology or printing Z-axis, wherein the Z-axis can be designed to be a straight line, a curve and other shapes.

Description

technical field [0001] The invention belongs to the fields of digital modeling, electronic application and the like. Background technique [0002] Projected capacitive touch film is a kind of sensing film mainly packaged with fine wires. It integrates the advantages of precise sensing positioning, flexibility and high transparency. It is used for precise touch positioning of touch screens above 12 inches, and is also used in precise Interactive projection. [0003] Projected capacitive technology is a kind of horizontal and vertical electrode arrays made on the surface of glass or transparent film. These horizontal and vertical electrode capacitance changes are used to detect finger touches. According to the difference in capacitance generation, it is divided into two types: Type: self-capacitance film and mutual capacitance film. Self-capacitance is the capacitance between the sensing block and the ground. When an excitation signal is applied to the sensing block, due to ...
