Abstract
The invention discloses a modified capacitive touch screen comprising a top panel and a sensor layer disposed on one side of the top panel. A glue layer is arranged between the top panel and the sensor layer. The modified capacitive touch screen is characterized in that the top panel is made of a GLASS layer, a plurality of ITO wire layers are arranged between the GLASS layer and the glue layer, and an intermediate partition is arranged between each two adjacent ITO wire layer; in addition, two ITO wire layers are arranged between the GLASS layer and the glue layer and an intermediate partition is arranged between the ITO wire layers. The modified capacitive touch screen has the advantages that the structure is simpler, true multi-point touch can be realized, cost is greatly reduced, the thickness is smaller than that of other structures, machine design space is greatly expanded, the modified capacitive touch screen is good in using effect, and the service life of the modified capacitive touch screen is guaranteed.
Description
Technical field
The invention belongs to touch-screen field, specifically, relate to a kind of improved capacitive touch screen.
Background technology
Along with scientific and technological development, the progress of technology, touch-screen is widely used on the electronic products such as mobile phone, GPS, panel computer.Be all LENS+GLASS SENSOR structure at every projection-type capacitive touch screen on the market at present, LENS+FILM SENSOR structure.Said structure can be ITO FILM or ITO GLASS by top panel (GLASS or PET material), optical cement, bottom SENSOR(SENSOR material) form.
The material of top panel is GLASS or PET material, but the complex process of GLASS panel and SENSOR laminating needs high-end devices and laminated material, affect production efficiency and production capacity, so cause the touch-screen cost of GLASS panel high, complex process, price is also quite high.PET material is in outward appearance and touch texture and surperficial scratch-resistant hardness, more a bit weaker than GLASS panel, affects result of use and the serviceable life of touch-screen.
Summary of the invention
The technical problem to be solved in the present invention is to overcome above-mentioned defect, provide a kind of simple in structure, cheap, result of use is good and the improved capacitive touch screen of long service life.
For addressing the above problem, the technical solution adopted in the present invention is:
A kind of improved capacitive touch screen, comprise top panel and the sensor layer that is arranged on top panel one side, between top panel and sensor layer, be provided with adhesive-layer, it is characterized in that: described top panel is GLASS layer, between GLASS layer and adhesive-layer, be provided with at least two-layer ITO line layer, between adjacent ITO line layer, be provided with intermediate interlayer.
Say further:
Between described GLASS layer and adhesive-layer, be provided with two-layer ITO line layer, between ITO line layer, be provided with intermediate interlayer, and intermediate interlayer is the interlayer of being made up of silicon dioxide.
Furthermore:
Described adhesive-layer is the adhesive-layer of being made up of OCA optical cement, silica gel or acrylic glue.
Owing to having adopted technique scheme, compared with prior art, the top panel in the present invention comprises GLASS layer, between GLASS layer and adhesive-layer, be provided with two-layer ITO line layer, between two-layer ITO line layer, be provided with intermediate interlayer, the effect of intermediate interlayer is isolated levels ITO, prevents short circuit.Such design, reaches in structure and more simplifies, and can realize true multiple point touching, same, and cost of the present invention significantly reduces, and other the structure of Thickness Ratio of entirety is thin, has greatly expanded the design space of complete machine.In addition, result of use of the present invention is good, and has ensured serviceable life.
Below in conjunction with the drawings and specific embodiments, the invention will be further described simultaneously.

Such design, reaches in structure and more simplifies, and can realize true multiple point touching, same, and the cost of the present embodiment significantly reduces, and other the structure of Thickness Ratio of entirety is thin, has greatly expanded the design space of complete machine.In addition, the present embodiment result of use is good, and has ensured serviceable life.
Embodiment 2:
All the other are identical with described embodiment 1, and difference is, is provided with two-layer ITO line layer 32 between described GLASS layer 31 and adhesive-layer 2, be provided with intermediate interlayer 33, and intermediate interlayer 33 is interlayers of being made up of silicon dioxide between ITO line layer 32
In the present embodiment, top panel 3 comprises GLASS layer 31, between GLASS layer 31 and adhesive-layer 2, be provided with two-layer ITO line layer 32, two-layer ITO line layer 32 just can meet operation and the control under prior art condition, so selecting two-layer ITO line layer is optimal selection, in addition, the effect of intermediate interlayer 33 is isolated levels ITO, prevents short circuit.
Embodiment 3:
All the other are identical with described embodiment 1, and difference is, described adhesive-layer 2 is OCA optical cement, silica gel or acrylic glue.
What in the present embodiment, adhesive-layer adopted is the one in OCA optical cement, silica gel or acrylic glue.Wherein, best embodiment is to adopt OCA optical cement.
The present invention is not limited to above-mentioned preferred implementation, and anyone should learn the structural change of making under enlightenment of the present invention, and every have identical or akin technical scheme with the present invention, all belongs to protection scope of the present invention.
