[embodiment]
Shown in Fig. 2,3,4, in capacitance type touch control screen shown in the utility model, comprise transparent substrate 20, be generally clear glass and make.Side at substrate 20 is a face 21, and opposite side is an air surface 22.Face 21 1 sides of substrate are provided with touch screen rete 10, towards the backlight setting, are used for signal that touch sensitive point place produces and the metal routing by wherein to be transferred to chip and to calculate touch point position.Between substrate face 21 and touch screen rete 10, be provided with mask layer 30.
Generally include ITO layer 11 and conductive layer 12 in the touch screen rete 10, the metal routing 12a in the conductive layer 12 is used for ITO layer 11 is electrically connected with chip.In order not have influence on the visuality of touch screen backlight, metal routing 12a distribute usually be arranged on touch screen rete 10 around.In order to shelter from metal routing 12a, mask layer 30 also be arranged on substrate 20 around and corresponding with the pattern of metal routing 12a, be generally the shape of rectangle frame.Mask layer 30 preferably adopts high light-proofness material to make, and as potpourri of resin or metal or metal and metal oxide etc., is preferably the hopcalite of Cr and Cr.When mask layer adopts the potpourri of can metal oxide to make, be preferably between mask layer 30 and the touch screen rete 10 and set up one deck dielectric film 40, this dielectric film 40 covers whole mask layer 30, i.e. the pattern that the pattern of dielectric film 40 formation and mask layer 30 form is complementary, and plays insulating effect.
In capacitance type touch control screen described in the utility model, the structure of touch screen rete 10 can be various patterns, as long as it is arranged on the single face of substrate 20.As shown in Figure 3, in first embodiment of capacitance type touch control screen described in the utility model, what the structure of touch screen rete 10 adopted is the touch-screen rete structure of single-surface double-layer.Particularly; comprise the first direction ITO layer 11a, insulation course 13, second direction ITO layer 11b, conductive layer 12 and the rete protective seam 14 that are successively set on substrate face 21; the signal that the ITO of both direction senses contact position transfers to chip by the metal routing 12a in the conductive layer and calculates, thereby obtains the position of contact.And metal routing 12a is arranged on position all around, position around the mask layer 30 of corresponding substrate air surface 22 sides also is arranged on.
As shown in Figure 4, in second embodiment of capacitance type touch control screen described in the utility model, what the structure of touch screen rete 10 adopted is the touch-screen rete structure of bridge type.Particularly, comprise ITO layer 11, insulation course 13, conductive layer 12 and the rete protective seam 14 that is successively set on substrate face 21 1 sides.Wherein, the ITO11a of both direction, 11b are arranged on in one deck and mutually insulated, and the ITO of first direction is continuous; The ITO of second direction is cut off by the ITO of first direction and is electrically connected by the metal bridge 12b that is arranged in conductive layer.Equally, position around the metal routing 12a in the conductive layer is set at, position around the mask layer 30 of corresponding substrate air surface 22 sides also is arranged on.In this embodiment, described mask layer can adopt resin material to make, and need not to be provided with the dielectric film of mask film covering layer this moment between mask layer and the touch screen rete again.
Add man-hour, can adopt following step to process above-mentioned capacitance type touch control screen:
Elder generation's prepared substrate 20 is specially the substrate 20 of preparing required specification, is generally tempered glass etc., with the side to be processed (being face 21) of substrate 20 towards same direction setting; Clean up with the processing side with substrate 20 such as clean-out system, and dry.Make mask layer 30 in substrate face 21 1 sides again, when mask layer 30 adopts the material of potpourri of metals and/or metal oxide, adopt sputtering process to make, metal routing 12a distribution patterns adapts in the pattern of the cover plate that adopts during sputter and the default conductive layer.Process touch screen rete 10 in substrate face 21 1 sides again, at this moment, mask layer 30 between substrate 20 and touch screen rete 10 just in time can shelter from conductive layer metal routing 12a in the touch screen rete 10, has guaranteed not to be subjected to from the viewing area of substrate air surface 22 1 sides the influence of metal routing 12a.
When mask layer 30 adopts resin materials, can make one deck mask in substrate face 21 1 sides by coating processes, again to mask expose, development, etching, remaining mask forms mask layer 30; Metal routing 12a distribution patterns adapts in same with the default conductive layer of pattern of the employed figure of getting cover plate of when exposure.Process touch screen rete 10 in substrate face 21 1 sides again, at this moment, mask layer 30 just in time can shelter from and touch metal routing 12a.
In the job operation of above-mentioned capacitance type touch control screen, between mask layer 30 and touch screen rete 10, also can be provided with dielectric film 40, especially when mask layer 30 adopts the potpourri of metal and/or metal oxide to make.This dielectric film 40 can adopt the sensitization insulating material to make according to the operation of coating, exposure, development and etching.On the one hand, dielectric film 40 can separate mask layer 30 and 10 insulation of touch screen rete; On the other hand, dielectric film 40 can also increase the adhesion of substrate face 21 1 sides, makes that touch screen rete 10 is easier of substrate face 21 1 sides.
In above-mentioned job operation, by between substrate face 21 and touch screen rete 10 mask layer 30 being set, processing is got up very convenient.Utilize this mask layer 30 just can shelter from metal routing 12a, and do not need to be provided with again the transparent cover plate that is sprayed with black ink, thereby avoided the influence of cover plate to the touch screen transmissivity, make that the transmissivity of whole touch screen is higher, and there be not the reflection of cover plate to the ITO layer, make that the contrast of touch screen is higher, visual effect is better, thereby can reduce the use power of backlight greatly.Simultaneously,, avoided when adopting bilateral structure, need having processed the inconvenience that face 21 is implemented safeguard measure, made whole manufacturing procedure more easy, improved production efficiency a basic side because all retes are all processed in a basic side; And can guarantee the levelability of substrate air surface 22 1 sides, the feel during touch is better.
In addition, in order to cooperate the outward appearance of corresponding touch-control product integral body, mask layer 30 adds the material that has color after can selecting different materials for use in existing material, mask layer 30 can show different colors as required when making from the whole touch screen of substrate air surface 22 observations, thereby makes the touch-control product obtain better appearance.
The above embodiment has only expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
