Abstract
The invention discloses a double-sided metal wired capacitive screen functional plate comprising a glass substrate, wherein the top surface of the glass substrate is sequentially provided with an upper shadow eliminating layer, an upper metal wiring layer and a top shadow eliminating layer from the top down; the bottom surface of the glass substrate is sequentially provided with a lower shadow eliminating layer, a lower metal wiring layer and a bottom shadow eliminating layer from the top down; metal wiring is performed on the whole surfaces of both the upper and lower metal wiring layers, the impedance of the upper shadow eliminating layer is matched with that of the upper metal wiring layer, and the impedance of lower upper shadow eliminating layer is matched with that of the lower metal wiring layer. According to the double-sided metal wired capacitive screen functional plate provided by the invention, a traditional ITO wiring mode is abandoned, and double-sided metal wiring is used, so that conductive performance of the functional plate is greatly improved; transmittance of the functional plate is enhanced by using the shadow eliminating layers matched with metal wiring, so that metal wiring traces are not significant, a metal circuit shape is not prone to appear on the appearance of the plate; and in addition, ITO coating and ITO yellow light technologies are not needed during manufacturing, so that cost and production time of products are saved, efficiency is improved, productivity is increased, and production value is enhanced.
Description
Technical field
The present invention relates to touch screen technology field, specifically a kind of capacitance plate functional sheet of double-sided metal cabling.
Background technology
With growing day by day, the intelligent electronic device such as mobile phone, panel computer of multimedia equipment, in life everywhere
It can be seen that, these equipment mostly use touch-screen as its collection and the instrument of identification information, and touch-screen is because permeability is strong, manipulation
Simple the advantages of, obtain increasingly being widely applied.
At present, the application of capacitive touch screen is the most universal, and the capacitive touch screen of wherein double-layer glass structure is compared
Single-glass structure, has the advantages that to support true multiple spot, the degree of accuracy is higher, translucency is high, hand-written effect is good.Double glazing knot
Structure generally comprises cover plate and functional sheet, and its touch function is realized on functional sheet.
At this stage, the face interior cabling on functional sheet is ITO cablings, and ITO cablings have been got over due to the limitation of electric conductivity
To be more difficult to meet the requirement of touch-screen handling.
The content of the invention
It is an object of the invention to provide a kind of capacitance plate functional sheet of double-sided metal cabling, the functional sheet uses two-sided gold
Category cabling, improves electric conductivity, and with good penetrability, outward appearance is less prone to metallic circuit shape.
The technical solution adopted for the present invention to solve the technical problems is：
A kind of capacitance plate functional sheet of double-sided metal cabling, including glass substrate, glass substrate top surface are sequentially provided with from the bottom to top
On disappear shadow layer, upper metal routing layer and top disappear shadow layer, glass substrate bottom surface is from top to bottom sequentially provided with down the shadow layer that disappears, lower metal walks
Line layer and bottom disappear shadow layer, and upper metal routing layer and lower metal routing layer are whole face metal routing, it is described on disappear shadow layer and upper gold
Belong to routing layer matches impedances, under disappear shadow layer and lower metal routing layer matches impedances.
The beneficial effects of the invention are as follows, give up traditional ITO cabling modes, using double-sided metal cabling, it is greatly enhanced
The electric conductivity of functional sheet；Using the shadow layer that disappears matched with metal routing, strengthen the transmitance of functional sheet, make metal routing
Vestige is not obvious, and outward appearance is less prone to metallic circuit shape；In addition, during fabrication without ITO plated films and ITO gold-tinted techniques, section
Cost-saving and product activity duration, raising efficiency, the production capacity that increases, the lifting output value.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples：
Fig. 1 is structural representation of the invention.
Specific embodiment
As shown in figure 1, the present invention provides a kind of capacitance plate functional sheet of double-sided metal cabling, including glass substrate 1, glass
The top surface of substrate 1 is sequentially provided with the shadow layer 2a that disappear, upper metal routing layer 3a and top and disappears shadow layer 4a, the bottom surface of glass substrate 1 from the bottom to top
The shadow layer 2b that disappear, lower metal routing layer 3b and bottom is from top to bottom sequentially provided with down to disappear shadow layer 4b, upper metal routing layer 3a and lower metal
Routing layer 3b is whole face metal routing, it is described on disappear the matches impedances of shadow layer 2a and upper metal routing layer 3a, under disappear shadow layer
The matches impedances of 2b and lower metal routing layer 3b.
During specific manufacture, glass substrate 1 can be using conventional function sheet glass, and the shadow layer 2a that above disappear disappears the work of shadow layer 2b with
The effect that industry parameter will combine after the etching of gold-tinted metal routing is adjusted scope, reaches effect optimal；Upper metal routing layer 3a
With plated film and the gold-tinted technique of lower metal routing layer 3b according to parameter request normal operation, when debugging disappears shadow scope, plated film ginseng
Number need to reach high-low limit value, the crawl of shadow scope of being easy to disappear and determine adjustment direction；Disappear shadow layer 4a and bottom of top disappears shadow layer 4b mono-
On the other hand aspect can also strengthen the shadow effect that disappears as the protective layer of metal routing.
The above, is only presently preferred embodiments of the present invention, and any formal limitation is not made to the present invention；Appoint
What those of ordinary skill in the art, in the case where technical solution of the present invention ambit is not departed from, all using the side of the disclosure above
Method and technology contents make many possible variations and modification, or the equivalent reality for being revised as equivalent variations to technical solution of the present invention
Apply example.Therefore, every content without departing from technical solution of the present invention, is done according to technical spirit of the invention to above example
Any simple modification, equivalent, equivalence changes and modification, still fall within the range of technical solution of the present invention protection.
