Abstract
The invention relates to a touch panel structure. Since an ITO (indium tin oxide)-film layer and a PET (polyethylene terephthalate) substrate are omitted, a produced TP (touch panel) is thinner. The invention further discloses a production technology of the touch panel structure. The production technology includes that an upper circuit is obtained by means of ITO ageing, film pressure drying, exposure, developing, etching, film stripping, silver paste printing, silver paste baking and lasering, a lower circuit is obtained by means of attaching a dry film layer on the back of an ITO, exposure and developing, the upper and lower circuits share one PET substrate, and a finished product is obtained by means of punching, FPC (flexible printed circuit) hot pressing and laminating. By the aid of the production technology, an OCA (optical clear adhesive) laminating technology is simplified, and alignment influence caused by a heating process is weakened.
Description
Technical field
The present invention relates to capacitance touching control product, specifically a kind of touch panel structure provided and production technology.
Background technology
Current GFF technological process: first aging by ITO, press dry film, exposure, development, etching, stripping, the printing of silver slurry, the baking of silver slurry, laser obtains rolling off the production line, then by OCA by roll off the production line fit to one piece, die-cut, the FPC hot pressing of sensor and glass gluing obtain touch-screen, the finished product structure complexity that existing technique is obtained, is fitted by two-layer ITO-film and forms.Its touch-screen is made up of a protective layer, two metallic circuit layers, two conductive membrane layers, two OCA and two substrates, and the finished product thickness obtained like this is comparatively large, and the trend that this and present society are tending towards ultrathin is disagreed.
Summary of the invention
The present invention is directed to the problems referred to above, provide a kind of ultrathin, cost low touch panel structure provided and easy to make, the simple touch panel structure provided production technology of flow process.
According to technical scheme of the present invention: a kind of touch panel structure provided, comprise the protective layer, OCA layer, metallic circuit layer, conductive membrane layer and the substrate layer that set gradually from outside to inside, the inside surface of described substrate layer is provided with photopolymer layer.
Further, described protective layer adopts cover plate.
Further, the frame-shaped structure of described metallic circuit layer to be surrounding be metallic circuit.
Further, described metallic circuit is starched by silver and is formed.
Further, described substrate layer is laminated polyester film.
Further, described photopolymer layer is Nano Silver photopolymer layer.
According to another technical scheme of the present invention: a kind of touch panel structure provided production technology, comprising:
First aging by ITO, press dry film, exposure, development, etching, stripping, the printing of silver slurry, the baking of silver slurry, laser reached the standard grade, described in reach the standard grade and be divided into protective layer, OCA layer, metallic circuit layer and conductive membrane layer from outside to inside successively;
Then enclose one deck photopolymer layer at the back side of described conductive membrane layer, rolled off the production line by exposure, development, a wherein said shared substrate layer of reaching the standard grade and roll off the production line;
Again by describedly reaching the standard grade, substrate layer and roll off the production line and obtain finished product through die-cut, FPC hot pressing, laminating.
Technique effect of the present invention is: the present invention makes certain improvements in original technical foundation, first aging by ITO, press dry film, exposure, development, etching, stripping, the printing of silver slurry, the baking of silver slurry, laser reached the standard grade, then one deck Nano Silver dry film is enclosed at the back side of this ITO, rolled off the production line by exposure, development, on to roll off the production line a shared pet substrate, then obtain finished product by die-cut, FPC hot pressing, laminating.One deck ITO-film that GFF constructs by this kind of technique changes Nano Silver dry film into, a slice OCA can be saved, simplify the attaching process of OCA, reduce heating processing cause to position influence, in addition, owing to having lacked one deck ITO-film and pet substrate, also make the TP made thinner, the trend of this and social ultrathin is also identical, and this type of dry film stable performance, is widely used.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
For enabling above-mentioned purpose of the present invention, feature and advantage become apparent more, and below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
In Fig. 1, comprise protective layer 1, OCA layer 2, metallic circuit layer 3, conductive membrane layer 4, substrate layer 5 and photopolymer layer 6 etc.
As shown in Figure 1, the present invention is a kind of touch panel structure provided and production technology, comprise the protective layer 1, OCA layer 2, metallic circuit layer 3, conductive membrane layer 4 and the substrate layer 5 that set gradually from outside to inside, protective layer 1 adopts cover plate usually, substrate layer 5 adopts laminated polyester film usually, and metallic circuit layer 3 is the frame-shaped structure of metallic circuit in surrounding, and centre covers without metallic circuit, transparent shape, metallic circuit is generally silver-colored line.
The present invention is provided with photopolymer layer 6 on the inside surface of substrate layer 5.Described photopolymer layer 6 is Nano Silver photopolymer layer, and its stable performance, is widely used, and has the function of impedance plating and etching.
Touch panel structure provided production technology of the present invention, first aging by ITO, press dry film, exposure, development, etching, stripping, the printing of silver slurry, the baking of silver slurry, laser reached the standard grade, described in reach the standard grade and be divided into protective layer 1, OCA layer 2, metallic circuit layer 3 and conductive membrane layer 4 from outside to inside successively; Then enclose one deck photopolymer layer 6 at the back side of described conductive membrane layer 4, rolled off the production line by exposure, development, a wherein said shared substrate layer 5 of reaching the standard grade and roll off the production line; Again by describedly reaching the standard grade, substrate layer 5 and roll off the production line and obtain finished product through die-cut, FPC hot pressing, laminating.One deck ITO-film that GFF constructs by this kind of technique changes photopolymer layer 6 into, a slice OCA can be saved, simplify the attaching process of OCA, reduce heating processing cause to position influence, in addition, owing to having lacked one deck ITO-film and pet substrate, also make the TP made thinner, become six layers from original nine layers, make touch panel structure provided more lightening.
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.
