Description
Technical field
The utility model relates to a kind of contact panel and shielding layer thereof.
Background technology
The OGS technology refers to the technology that directly forms ITO conducting film and sensor on cover glass, and a glass plays the double action of cover glass and touch sensor simultaneously.Obtain the OGS touch-screen through the glass after the OGS technical finesse after cutting.The G/G touch technology that the OGS technology is more traditional has a lot of advantages, as, can save a slice glass substrate, can save one bonding process on production process, thereby be conducive to reduce production costs, improve product yield.And the OGS touch-screen obtained has the characteristics such as light, thin, that light transmission is good.
Yet, in existing OGS processing procedure, the BM layer (Black Matrix, black matrix) that is used as cabling shielding and decoration functions must have enough large optical density (OD, Optical Density) numerical value, to reach the effect of complete shading.When adopting non-black especially white material is as shielding layer, its optical density is relatively less, and this also requires significantly to promote the thickness of shielding layer to a certain extent, but this can cause more than whole mobile phone will thicken 1mm.In addition, if only be coated with one deck white photoresistance, will see under the white edge frame and have a black to look effect, yield only reaches 40%.

The accompanying drawing explanation
The diagrammatic cross-section of the contact panel that Fig. 1 is an embodiment.
Embodiment
For above-mentioned purpose of the present utility model, feature and advantage can be become apparent more, below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.A lot of details have been set forth in the following description so that fully understand the utility model.But the utility model can be implemented much to be different from alternate manner described here, those skilled in the art can be in the situation that do similar improvement without prejudice to the utility model intension, so the utility model is not subject to the restriction of following public concrete enforcement.
Refer to Fig. 1, it is the diagrammatic cross-section of the contact panel 100 of an embodiment.Contact panel 100 comprises transparency carrier 10, conductive layer 20, shielding layer 30 and protective seam 40.
Transparency carrier 10 includes source region (active area) 12 and framework (frame) district 14, wherein framework region 14 be centered around active area 12 around.Substrate 10 can be selected and be beneficial to finger touch and light transmission preferably glass, transparent glasses lens or transparent passivation (passivation) material make.
Conductive layer 20 is arranged on the active area 12 of transparency carrier 10.Conductive layer 20 comprises a plurality of capacitance touching control induction electrodes, and its transparency conducting layer that is island is for example indium tin oxide (the indium tin oxide of rhombus; ITO) layer.In one embodiment, electrode with a line is to utilize formation capacitance touching control induction electrode directly to connect, the electrode of same row utilizes the bridging structure of conduction to be electrically connected, the resulting touch-control signal of the capacitance touching control induction electrode of every a line and each row can be passed to flexible circuit board (flexible print circuit by conductor structure, FPC) (not shown), be sent to integrated circuit (IC) (not shown) in touch control display apparatus via flexible circuit board again, carry out the processing of touch-control signal.
Shielding layer 30 is arranged on the framework region 14 of transparency carrier 10, for blocking pin configuration, and can block via this transparency carrier 10 and attempt to penetrate the light of this shielding layer 30.Shielding layer 30 comprises the white light resistance layer 32 that is arranged on framework region 14, is arranged on the black light resistance layer 34 on white light resistance layer 32 and is arranged on the grey photoresist layer 36 on black light resistance layer 34.
The composition of white light resistance layer 32 is mainly resin, and its Main Function is to make the position corresponding to framework region 14 of contact panel 100 be shown as white, thereby plays good decorative effect.The thickness of white light resistance layer 32 can be
(dust)～
be preferably
The composition of black light resistance layer 34 is mainly resin.Because the iris action of 32 pairs of light of white light resistance layer a little less than, therefore need black light resistance layer 34 as assisting the optical density that further improves shielding layer 30.The thickness of black light resistance layer 34 can be
if thickness is too large, broken string may appear in ITO, and the impedance meeting increases.Be preferably
The composition of grey photoresist layer 36 is mainly resin.Due to the thinner thickness of black light resistance layer 34, likely there is a little leak, therefore can use grey photoresist layer 36 that the leak of black light resistance layer 34 is blocked, realize farthest stopping that light penetrates.The thickness of grey photoresist layer 36 can be
be preferably
Protective seam 40 covers on transparency carrier 10 comprehensively, completes the making of contact panel 100 as shown in Figure 1.The material of protective seam 40 is such as being the materials such as acryl resin, silicon nitride, monox or silicon oxynitride.
The shielding layer 30 of above-mentioned contact panel 100 comprises white light resistance layer 32, black light resistance layer 34 and grey photoresist layer 36, interaction by three photoresist layers, thereby can guarantee that naked eyes see only have white photoresistance reflectively realize white OGS, solved again the problem of white good productive rate simultaneously.
It is below the specific embodiment part.
