Description

Touch panel structure provided

Technical field

The utility model relates to a kind of touch panel structure provided, relates in particular to a kind of auxiliary articulamentum of metal that utilizes and is electrically connected the touch panel structure provided of quality to strengthen transparency conducting layer because of what connect that shielding layer has a ladder difference of height.

Background technology

In the prior art, general traditional capacitance type touch-control panel mainly is to add insulation course after forming transparency conducting layer, at last, add metal level to distinguish X and Y circuit, and be used as bridge formation structure or bridge joint rete by metal level, so that X or each infall of Y circuit can be connected in series is disclosed as TaiWan, China M355426 patent and M388686 patent.

In the prior art of above-mentioned M355426 patent and M388686 patent, the outer rim of contact panel can dispose and be electrically connected circuit, such as constituting by transparent conductive material, in order to transmit electric signal, can utilize lighttight shielding layer to be electrically connected circuit simultaneously, produce vision and beautify effect to cover.Therefore, X in the visible area of contact panel and Y circuit just can utilize the electrically conducting transparent articulamentum and be connected to and be electrically connected circuit, so the electrically conducting transparent articulamentum must cover shielding layer (that is being positioned at the contact panel outer rim) and substrate on the substrate.But, shielding layer can produce the ladder difference of height with substrate because of the thickness of itself, make the coverage rate of electrically conducting transparent articulamentum be easy to change or instability variation, and then the problem of electric contact or bad connection, the fiduciary level that influences the product yield and manipulate take place because of processing procedure.

Therefore, need a kind of additional transparent conduction articulamentum that utilize to cover touch panel structure provided on the electrically conducting transparent articulamentum, to solve in the above-mentioned prior art because of the not good problem that is caused of electrically conducting transparent articulamentum coverage rate.

The utility model content

Fundamental purpose of the present utility model is providing a kind of touch panel structure provided, comprise the shielding layer of storehouse on glass substrate, the electrically conducting transparent articulamentum, conductive pattern layer, insulation course and metal are assisted articulamentum, wherein conductive pattern layer is configured to X and Y circuit in orthogonal mode, and be arranged in the visible area of contact panel, and shielding layer is positioned at outside the visible area, and the shielding layer of electrically conducting transparent articulamentum cover part, make shielding layer be connected to conductive pattern layer by the electrically conducting transparent articulamentum, the electrically conducting transparent articulamentum of insulation course overlay masking layer and part, the insulation course of the auxiliary articulamentum cover part of metal and the electrically conducting transparent articulamentum of part.

Therefore, of the present utility modelly touch panel structure providedly can strengthen and solve the electrically conducting transparent articulamentum causes electric contact or bad connection because of the ladder height difference problem by the auxiliary articulamentum of metal.

Embodiment

Those skilled in the art below cooperate Figure of description and element numbers that embodiment of the present utility model is done more detailed description, so that can implement after studying this instructions carefully according to this.

Consult Fig. 1, be the touch panel structure provided synoptic diagram of the utility model.As shown in Figure 1, touch panel structure provided shielding layer 20, electrically conducting transparent articulamentum 30, conductive pattern layer 32, insulation course 40 and the metal of storehouse on glass substrate 10 that comprise of the present utility model assisted articulamentum 50, wherein conductive pattern layer 32 is configured to orthogonal X and Y circuit, and be arranged in the visible area of contact panel, and visible area is meant and display device (the scheming not shown) image that is produced can be demonstrated and be available for users to carry out the zone of touch operation through transmission.

Shielding layer 20 is stacked on the glass substrate 10, and is positioned at outside the visible area, and is positioned at the outer rim of glass substrate 10.Shielding layer 20 is made of light tight material, can be the combination of black material, black matrix" (Black Matrix) or look resistance and plated film, in order to cover the light that display device is launched.

The shielding layer 20 of electrically conducting transparent articulamentum 30 cover parts and glass substrate 10 make shielding layer 20 to be connected to the conductive pattern layer 32 of storehouse on glass substrate 10 by electrically conducting transparent articulamentum 30.Because shielding layer 20 thickness own can be poor with glass substrate 10 generation ladder heights, so the 30 meeting formation of electrically conducting transparent articulamentum have stepped 34 unsmooth surface.

In addition, electrically conducting transparent articulamentum 30 and conductive pattern layer 32 can be made of transparent conductive material, and such as indium tin oxide (ITO), and electrically conducting transparent articulamentum 30 can further be connected to external circuit (scheming not shown).

Insulation course 40 can be by silicon dioxide (SiO ₂) constitute, and cover shielding layer 20 and the part electrically conducting transparent articulamentum 30, and the auxiliary articulamentum 50 of metal covers partial insulating layer 40 and electrically conducting transparent articulamentum 30 partly at least, in order to reinforcement 30 pairs of glass substrates 10 of electrically conducting transparent articulamentum and shielding layer 20 storehouse quality, can avoid taking place to peel off mutually and cause electric bad.

The auxiliary articulamentum of metal 50 is made of conductive metallic material, and the conductive metallic material of the auxiliary articulamentum of metal can comprise silver-colored line, aluminium, copper or aluminium copper.The structure that is noted that Fig. 1 applicable to the X circuit of conductive pattern layer 32 and Y circuit at least one of them.

The characteristics of above-mentioned the utility model method for making are, utilize the auxiliary articulamentum of metal to cover insulation course and electrically conducting transparent articulamentum, cause electric badly to avoid the electrically conducting transparent articulamentum that glass substrate and shielding layer are taken place to peel off mutually, and then improve the yield of product and actually use operational fiduciary level.。

The above only is in order to explain preferred embodiment of the present utility model; be not that attempt is done any pro forma restriction to the utility model according to this; therefore; all have in that identical utility model spirit is following do relevant any modification of the present utility model or change, all must be included in the category of the utility model intention protection.
