Description
Technical field
It the utility model is related to touch screen technology field, more particularly to a kind of OGS touch screen.
Background technology
Touch-screen is a kind of input equipment, can conveniently realize interacting for people and computer and other portable mobile apparatus
Effect.In recent years, the capacitance touch screen based on tin indium oxide (ITO) transparent conductive film, particularly projecting type capacitor screen can enter
Row refers to identification more, realizes multi-point touch, is widely used in mobile interchange equipment, such as smart mobile phone, Portable tablet personal computer.
OGS is a kind of full fitting scheme that current most manufacturers use, and the full coating technique of most main flow at present.
OGS technologies are exactly that touch screen and protective glass are integrated, and ITO conductive layer is plated on the inside of protective glass, is directly being protected
Protect and plated film and photoetching are carried out on glass, due to saving a sheet glass and being once bonded, thinner and cost that touch-screen can be done
It is lower.
After first plated film traditional OGS there is ink area color, two layers of conductive film layer (lower floor ITO in printing-ink production method
With metallic conduction film layer) overlap joint the problems such as, and manufacture craft is more complicated；Film-plating process is effectively improved first printing-ink again after improvement
Ink area color and two conductive layers (lower floor ITO and metallic conduction film layer) overlap joint problem, and technique linking is smoothly, but this work
Skill is significantly larger than ITO conductive film layer coating film thicknesses due to ink printing step thicknesses.Causing ito film layer, climbing is deposited at ink edge
In ITO conductive film layer risk of breakage, product may cause open circuit to cause using process in user due to this position ito film fault rupture
Product function is unstable, or even gradually failure.Therefore optimization Product Process lifting product function yield makes as OGS touch screen
An urgent demand in field.
Utility model content
In view of the above-mentioned problems, the utility model provides, a kind of preparation technology is simple, the cost of material is low, process rate is high
OGS touch screen.
In order to solve the above technical problems, technical scheme is used by the utility model：A kind of OGS touch screen, including it is saturating
Bright cover-plate glass, the ink layer for being located at transparent cover plate glass surrounding, the metal level being located on ink layer, set on the metal layer with it is whole
The ITO conductive layer of individual glassy zone, the conductive carbon paste layer being located between metal level and viewfinder area, the guarantor being located on conductive carbon paste layer
Shield ink layer and the FPC being bundled on electrode circuit.
Further, the transparent cover plate glass is the soda-lime glass and alumina silicate chemically reinforced glass after reinforcing,
Thickness 0.5mm-2.0mm, at least 6 grades or more of Mohs' hardness.
Further, the ink layer insulation impedance is more than 10 10 powers, and the hardness after baking is in more than 4H.
Further, the protection ink layer insulation impedance being located on conductive carbon paste layer is more than 10 10 powers, face
Color approaches with periphery ink layer color.
From the above-mentioned description to the utility model structure, compared to the prior art, the utility model has following excellent
Point：
The utility model is introduced directly into conductive carbon paste technique in ink step regional metal layer and ITO layer, aids in transition two
Person directly overlaps, and avoids that to reduce product function at the step caused by the fracture of ITO conductive film layers bad, improves system
The long-time stability of journey yield and product, preparation technology is simple, the cost of material is low.
Brief description of the drawings
The accompanying drawing for forming the part of the application is used for providing further understanding to of the present utility model, of the present utility model
Schematic description and description is used to explain the utility model, does not form to improper restriction of the present utility model.In accompanying drawing
In：
Fig. 1 is a kind of structural representation of OGS touch screen of the utility model.
Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only explaining
The utility model, it is not used to limit the utility model.
Embodiment
With reference to figure 1, a kind of OGS touch screen, wrap enough transparent cover plate glass 1, be located at the ink layer of transparent cover plate glass surrounding
2nd, the metal level 3 that is located on ink layer, set on the metal layer and the ITO conductive layer 4 of whole glassy zone, be located at metal level with regarding
Conductive carbon paste layer 5, the protection ink layer 6 being located on conductive carbon paste layer and the flexible wires being bundled on electrode circuit between window area
Road plate 7, the described FPC being bundled on electrode circuit, connection and electric action are played, as signal output.
The transparent cover plate glass 1 is soda-lime glass and alumina silicate chemically reinforced glass after reinforcing, thickness
0.5mm-2.0mm, surface must be very smooth bright and clean, and light transmission will get well, and integrally have certain toughness, by pressure not yet
Slight crack, at least 6 grades or more of Mohs' hardness, it is ensured that mobile phone glass there are enough surface strengths, wear-resisting to be not easy to scratch occurs.
The insulation impedance of ink layer 2 is more than 10 10 powers, and shielding is good, high-temperature baking resistant, resistance to ultrasonic wave cleaning,
Acid-alkali-corrosive-resisting, the hardness after baking is in more than 4H.
The metal level 3 is using printing or vacuum coating mode, good conductivity, high-temperature baking resistant.
The ITO conductive layer 4 for setting whole glassy zone on the metal layer uses vacuum coating, and uses laser ablation work
Skill prepares required circuitous pattern.
The protection insulation impedance of ink layer 6 being located on conductive carbon paste layer is more than 10 10 powers, the same periphery of color
Ink layer color approaches.
Operation principle：It is bonded to each other by glass surface flaggy and film layer, forms mutual capacitance, when the finger of people touches screen
When, because human body has siphoned away a part of electric capacity, therefore the amount of mutual capacitance will be reduced, and now, then judge that this has finger to touch screen,
Again by relevant treatment, the position coordinates that finger touches is calculated.And conductive carbon paste is as ITO conductive film layers and metal conductive film
Layer auxiliary transition overlap joint, is eliminated because ink edge step highly causes the fracture of ITO conductive film layers to cause output signal is unstable to ask
Topic.
The utility model is introduced directly into conductive carbon paste technique in ink step regional metal layer and ITO layer, aids in transition two
Person directly overlaps, and avoids that to reduce product function caused by step goes out the fracture of ITO conductive film layers bad, improves system
The long-time stability of journey yield and product, preparation technology is simple, the cost of material is low.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
