Problems solved by technology

When this kind of sensor realizes its function, there is a limitation of the sensing detection distance. If the original structure design of the touch panel or film is unreasonable, there will be a situation of insensitivity during detection, which will affect the use of the product.
[0005] And, above-mentioned two kinds of switches all exist the defect that assembly is inconvenient

Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0022] FIG. 1 shows the layer structure diagram of the first embodiment of the touch sensitive film of the present invention. As shown in the figure, the touch sensitive film of this embodiment includes a touch panel and a conductive circuit layer; the touch panel 1 is a layer of film sheet, and the touch panel has two surfaces: a touch surface 11 for touch sensing and its back side (not shown in the figure); a layer of pattern symbols 21 is printed on the back of the touch surface 11 to form a pattern symbol layer 2; Touch key line 31 and its circuit lead-out line 32 . Wherein, the pattern symbol 21 corresponds to the capacitive touch key line 31 overlapping up and down.

[0023] A layer of plastic layer 4 can also be coated on the outside of the conductive circuit layer 3 to achieve an integrated structure and improve the antifouling ability of the ...

Abstract

The invention discloses a touch sensitive film, comprising a touch panel and an electric conducting circuit layer, wherein the touch panel is provided with a touch face and a back face of the touch face; the touch panel is a film sheet; a pattern symbol layer is printed on the back face of the touch face; and the electric conducting circuit layer is a layer of capacitance sensitive touch key circuit and circuit outgoing lines thereof, which is printed outside the pattern symbol layer. By adopting the structure, the touch sensitive film is simple in structure, short in sensitive distance and high in sensitivity of key touch sense. A plastic layer is coated outside the electric conducting circuit layer, thus forming an integrated enclosed structure, thus realizing water resistance, moisture resistance, anti-pollution and other effects, thereby avoiding influences on the touch sensitive film due to changes of external environments so as to further improve touch life of keys.

Description

technical field [0001] The invention relates to the field of touch-sensitive switches, in particular to a touch-sensitive film. Background technique [0002] Touch sensor switches are widely used in people's daily life, such as induction cooker, refrigerator and other fields. There are mainly two types of touch-sensitive switches in the prior art: touch-type and film-type: [0003] Touch type: The panel is shaped to avoid the air, and then a hard touch switch is added to realize the touch function. Since this kind of sensor is equipped with a switch after the panel is evacuated, the moisture resistance and anti-fouling performance of the sensor are poor, and the operator needs to directly touch the switch itself during operation, which will affect the life of the product; [0004] Thin-film type: Paste an inductive film on the bottom of the touch panel to realize the touch function. When this kind of sensor realizes the function, there is a limitation of the sensing detec...
