Fig. 1 is the cross-sectional view of the touch-screen of one embodiment of the invention, as shown in Figure 1, this touch-screen is typical OGS touch-screen 100, it comprises cover glass 110, described cover glass 110 has front and back, in its front, be formed with the touch controllable function layer 120 of one with it, this touch controllable function layer 120 is realized all touch sense function of touch-screen, with reference to figure 2, the touch-screen 100 of the present embodiment with display panels 130 in conjunction with time, by touch controllable function layer 120 and 130 pairs of subsides of display panels, preferably adopt optical cement 180, form touch-screen display.
In the present embodiment, at the back side of described cover glass 110, be directly provided with one deck molybdenum oxide layer 140.The setting of molybdenum oxide layer 140, can make the skin hardness of touch-screen reach 9H, and the hardness own compared with cover glass 110 is also high, and tool has good wearability, and can be good at preventing that screen surface is scratched.Simultaneously, experiment shows, due to the existence of molybdenum oxide layer 140, the four-point bending intensity of this touch-screen also on average improves 50-100MPa than existing touch-screen compressive strength, the falling height of the existing touch-screen of falling sphere Performance Ratio has improved 10cm, has good crash resistance energy.
With reference to figure 3; the cross-sectional view of the touch-screen of another embodiment; it shows another typical OGS touch-screen; it comprises cover glass 210; described cover glass 210 has front and back; in its front, be formed with the touch controllable function layer 220 of one with it, this touch controllable function layer 220 is realized all touch sense function of touch-screen.It is compared with the touch-screen in Fig. 1, and difference is that its molybdenum oxide layer 240 is to be indirectly arranged on cover glass 210, between molybdenum oxide layer 240 and cover glass 210, also has one deck for improving the AR high transmittance film layer 250 of transmitance.
The setting of above-mentioned molybdenum oxide layer 140, can make the skin hardness of touch-screen reach 9H, and the hardness own compared with cover glass 110 is also high, and tool has good wearability, and can be good at preventing that screen surface is scratched.Simultaneously, experiment shows, due to the existence of molybdenum oxide layer 140, the four-point bending intensity of this touch-screen also on average improves 50-100MPa than existing touch-screen bending strength, the falling height of the existing touch-screen of falling sphere Performance Ratio has improved 10cm, has good crash resistance energy.That is to say, identical surface property all can be obtained in the back side that molybdenum oxide layer is set directly at the back side of cover glass or is indirectly arranged on cover glass.
In addition, as preferably, on molybdenum oxide layer 240, be also provided with the anti-fingerprint film 260 of one deck, that is to say, molybdenum oxide layer 240 is not necessarily as the superficial layer of whole touch-screen.Yet after having increased anti-fingerprint film 260, the hardness of touch screen surface will decline to some extent, its hardness is the hardness of anti-fingerprint film 260, is conventionally merely able to reach 8H, and still, molybdenum oxide layer 240 still can significantly improve the wearing quality of whole touch-screen.Except wearing quality, bending strength and resistance to two data targets of performance that fall are all less than changing.
With reference to figure 4; the cross-sectional view of the touch-screen of another embodiment; it shows a typical G+G/G+P/G+F/G+F+F touch-screen; this touch-screen comprises cover glass 310 and is fitted in its positive touch screen function sheet 370; touch screen function sheet 370 is realized all touch sense function of touch-screen, between cover glass 310 and touch screen function sheet 370, preferably by optical cement 380, fits.The back side at described cover glass 310 is directly provided with one deck molybdenum oxide layer 340.
Equally; similar with the 2nd embodiment provided by the present invention, in the present embodiment, the middle layer as AR high transmittance film layer can also be set between cover glass 310 and molybdenum oxide layer 340 equally; on the surface of molybdenum oxide layer 340, also the superficial layer as anti-fingerprint film can be set.
In addition, for the present invention, also provide In-cell or On-cell touch-screen display, specifically, it comprises the cover glass in above-described embodiment and the display panels with touch controllable function of fitting with this cover glass.
The present invention also provides the method that forms molybdenum oxide layer on cover glass; the method is on cover glass; take metal molybdenum as target, and the mixed gas of argon gas and oxygen of take is sputter gas, by the mode of magnetically controlled DC sputtering, directly or indirectly plates one deck molybdenum oxide layer.
As molybdenum oxide layer of the present invention, there is good light transmission and insulativity.If only using argon gas as sputter gas, the transmitance of the molybdenum oxide layer of preparing is lower, and reflectivity is higher, the similar mirror of appearance, and be conductive metal film, in the process of sputter, except argon gas, if pass into again some oxygen, can change transmitance and the electric conductivity of whole molybdenum oxide layer.In the present embodiment; the ratio that oxygen accounts for mixed gas is not less than 18%; the effect of the molybdenum oxide layer forming is with this understanding best; the transmitance of the molybdenum oxide layer obtaining is in 99.8%-100% scope; at glass, substantially plate after molybdenum oxide layer; the whole transmitance that molybdenum oxide layer and cover glass form approaches the transmitance (between cover glass transmitance 91%-92%) of cover glass itself substantially, therefore, increases molybdenum oxide layer to the not impact of the transmitance of integral product.
If oxygen accounts for the ratio of mixed gas and is less than 18%, the transmitance of molybdenum oxide layer will be less than 99.8%, cause affecting the transmitance of integral product; In the situation that other conditions are constant, the ratio that accounts for mixed gas along with oxygen progressively reduces, the reduction that the transmitance of molybdenum oxide layer will be gradually, and insulativity can variation, at oxygen proportion, is 0 o'clock, and molybdenum oxide layer becomes conducting film, and transmitance drops to 93%.Yet, oxygen accounts for the ratio of mixed gas neither be more high better, when the ratio that accounts for mixed gas when oxygen is greater than 20%, it is substantially identical that the performance of molybdenum oxide layer and oxygen account for the molybdenum oxide layer performance obtaining when ratio of gas mixture is 18%-20%, but sputtering yield can reduce, cause target consumption too large, high cost.
More than that better enforcement of the present invention is illustrated, but the invention is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent variations or replacement under the prerequisite without prejudice to spirit of the present invention, and the distortion that these are equal to or replacement are all included in the application's claim limited range.
