Equally, similar with the 2nd embodiment provided by the present invention, in the present embodiment, protect glass 310 and molybdenum oxide
The middle layer as AR high transmittance film layer can also be equally set between layer 340, on the surface of molybdenum oxide layer 340, can also be set
Set the superficial layer as fingerprint proof membrane.
In addition, for the present invention also provides In-cell or On-cell touch-screen displays, specifically comprising above-mentioned
Protection glass in embodiment and the liquid crystal display panel with touch function with the protection glass gluing.
The present invention also provides the method for forming molybdenum oxide layer on protection glass, this method is on protection glass, with gold
Category molybdenum is target, direct or indirect by way of magnetically controlled DC sputtering using the mixed gas of argon gas and oxygen as sputter gas
Plate one layer of molybdenum oxide layer.
As molybdenum oxide layer of the invention, there is good translucency and insulating properties.If only using argon gas as sputtering gas
The transmitance of body, the then molybdenum oxide layer prepared is lower, and reflectivity is higher, and appearance is conductive gold similar to mirror
Belonging to film in addition to argon gas, if being passed through some oxygen again, can change the transmitance of entire molybdenum oxide layer during sputtering
And electric conductivity.In the present embodiment, the ratio that oxygen accounts for mixed gas is not less than 18%, the molybdenum oxide layer formed with this condition
Effect it is best, the transmitance of obtained molybdenum oxide layer substantially plates molybdenum oxide layer in 99.8% -100% range, in glass
Afterwards, molybdenum oxide layer and the whole transmitance of protection glass composition are substantially close to transmitance (the protection glass for protecting glass itself
Between transmitance 91%-92%), therefore, increasing molybdenum oxide layer does not influence the transmitance of integral product.
If oxygen accounts for the ratio of mixed gas less than 18%, the transmitance of molybdenum oxide layer will cause to influence less than 99.8%
The transmitance of integral product；In the case where other conditions are constant, as the ratio that oxygen accounts for mixed gas gradually reduces, oxidation
The transmitance of molybdenum layer will be reduced gradually, and insulating properties can be deteriorated, and when oxygen proportion is 0, molybdenum oxide layer becomes conductive film, thoroughly
It crosses rate and then drops to 93%.However, the ratio that oxygen accounts for mixed gas is also not, the higher the better, when oxygen accounts for the ratio of mixed gas
When example is greater than 20%, the performance and oxygen of molybdenum oxide layer account for molybdenum oxide layer obtained when ratio of gas mixture is 18% -20%
It can be substantially the same, but sputtering yield can then reduce, and cause target consumption too big, cost is excessively high.
It is to be illustrated to preferable implementation of the invention, but the invention is not limited to the implementation above
