Abstract
The invention relates to a metal grid type touch panel structure and a manufacturing process thereof. The metal grid type touch panel structure comprises a protective layer, an OCA layer and a touch sensing layer which are sequentially arranged from outside to inside. An inner surface and an outer surface of the touch sensing layer are both provided with metal grids, a window is arranged in the middle of the touch sensing layer, circuits are distributed around the window, and the inner surface of the touch sensing layer is provided with an insulated ink layer for covering the circuits. The manufacturing process of the metal grid type touch panel structure refers to that the insulated ink layer is connected to the inner surface of the touch sensing layer in a printed mode. According to the metal grid type touch panel structure and the manufacturing process thereof, a explosion-proof membrane in the prior art is replaced by the insulated ink layer, so the light-transmitting rate of the window of the product is improved, the production cost of the product is lowered, and the reliability testing passing rate of the product is improved.
Description
Technical field
The present invention relates to the capacitive touch screen of the individual layer mutual tolerance structure in electronic product contact panel, specifically touch panel structure provided the and manufacture craft of a kind of wire netting lattice.
Background technology
Metal grill (Metal mesh) is a kind of transparent metal conductive material, and its resistance is low, and transmittance is high, and bending property is excellent, is widely used in middle large scale touch-screen at present.
Existing wire netting lattice contact panel; in order to protect metallic mesh material reverse side circuit; the phenomenon such as prevent the product function that causes due to scuffing bad; adopt the mode attaching blow-out disc at the whole plate of the reverse side of metallic mesh material; play protection product form and the effect of perimeter circuit, be convenient to subsequent processing and entirely fit operation.
But, adopt the mode attaching blow-out disc protection circuit to there is following shortcoming: 1, because blow-out disc has hidden product form, product form transmittance to be reduced; 2, blow-out disc unit price is high, adds the production cost of product.
Summary of the invention
The present invention is directed to the problems referred to above, provide a kind of transmittance high and the wire netting lattice that cost is low is touch panel structure provided and manufacture craft.
The touch panel structure provided technical scheme of wire netting lattice in the present invention is: a kind of wire netting lattice is touch panel structure provided, comprise the protective layer, OCA layer and the touch-control sensing layer that set gradually from outside to inside, inside and outside two surfaces of described touch-control sensing layer are provided with metal grill, the middle part of described touch-control sensing layer is form, be furnished with circuit around, the inside surface of described touch-control sensing layer be provided with the insulating oil layer of ink covering described circuit.
Further, described protective layer adopts cover plate.
Further, the inner side of described insulating oil layer of ink is provided with the coating layer protecting described form.
The technical scheme of the manufacture craft that the wire netting lattice in the present invention is touch panel structure provided is: described insulating oil layer of ink adopts mode of printing to be connected on the inside surface of described touch-control sensing layer.
Further, after described insulating oil layer of ink is completed for printing, carries out overlay film and protect described form.
Technique effect of the present invention is: the present invention adopts insulating oil layer of ink to replace blow-out disc of the prior art, improves the transmittance of product form, reduces the production cost of product, improves product reliability and trusts test percent of pass.
Embodiment
For enabling above-mentioned purpose of the present invention, feature and advantage become apparent more, and below in conjunction with embodiment, the present invention is further detailed explanation.
A kind of wire netting lattice in the present invention is touch panel structure provided, and comprise the protective layer, OCA layer and the touch-control sensing layer that set gradually from outside to inside, protective layer adopts cover plate usually.
Inside and outside two surfaces of touch-control sensing layer are provided with metal grill, and the middle part of touch-control sensing layer is form, is furnished with circuit around, the inside surface of touch-control sensing layer is provided with the insulating oil layer of ink covering circuit.
The inner side of insulating oil layer of ink can also be provided with the coating layer of protection form.
The touch panel structure provided manufacture craft of above-mentioned wire netting lattice is: protective layer, OCA layer and touch-control sensing layer adopt existing common process to make, and before full bonding process, form perimeter circuit adopt insulating oil layer of ink in mode of printing printing carry out protection circuit; After insulating oil layer of ink is completed for printing, overlay film protection form can also be carried out; Finally, full bonding process is gone to.
The present invention adopts the mode of printing insulating oil layer of ink on the circuit of form periphery to replace blow-out disc of the prior art, because insulating oil layer of ink does not hide form, therefore improves the transmittance of product form; Again because the cost of dielectric ink is lower than blow-out disc, reduce the production cost of product; In addition, also improve product reliability and trust test percent of pass.
Above to invention has been the enough detailed description with certain singularity.Belonging to those of ordinary skill in field should be appreciated that, the description in embodiment is only exemplary, make under the prerequisite not departing from true spirit of the present invention and scope change and all should belong to protection scope of the present invention.The present invention's scope required for protection is undertaken limiting by described claims, instead of limited by the foregoing description in embodiment.
