Abstract
The present invention relates to a kind of preparation method of anti-peeping code input device, utilize existing waste mobile phone screen, it is transformed, the polarizer of liquid crystal display screen of mobile phone top layer is removed, the screen now seen is white screen, and the top layer polarizer of removal is fabricated into polarising glass, if wanting to see clearly the content on display, user wearing polarized glasses are then needed, this function can effectively control visual range, reach peep-proof effect；Mobile phone screen touch screen functionality is retained, and password can be directly inputted on screen with reference to random keyboard, and the physical keyboard that the payment POS that the general supermarket of contrast, market are used is carried, random keyboard can improve confidentiality, pay safer；Smart mobile phone network-connectable, preferably can be docked with payment system；All kinds of app of installation can be downloaded, is integrated with life, makes it more intelligent；The design carries out secondary utilization to the old mobile phone being eliminated, and cost is not only greatly reduced but also more meets environmental protection theory.
Description
Technical field
The present invention relates to cipher input equipment technical field, specifically a kind of making side of anti-peeping code input device
Method.
Background technology
In today of electronic commerce times, the particularly all kinds of microcomputers of domestic, international popularization and application, computer network
Network is serviced, and too busy to get away use can input the cipher input of information code.The most frequently used cipher inputting keyboard is ten numerals of 0-9
The function key such as key and acknowledgement key.Because the arrangement position of each key is fixed, there is no peep-proof measure, it is special when user inputs password
When not being that password needs to repeatedly input, position data are easy to be spied on or be stolen pressed key for digit and the institute of the password, not only
Psychological burden is brought to user, and will also result in unnecessary risk.Peep-proof liquid crystal display of the prior art is set
Standby cost is higher, and can not be applied to payment system.
The content of the invention
It is higher for above-mentioned peep-proof liquid crystal display cost of the prior art, and payment system etc. can not be applied to
Problem, the present invention provides a kind of preparation method of anti-peeping code input device.
In order to solve the above technical problems, the technical solution adopted by the present invention is：
A kind of preparation method of anti-peeping code input device, comprises the following steps：
Step one：Waste and old smart mobile phone is taken, the top layer polarizer of LCDs is removed, retains bottom polarizer so that
Uniform light intensity is obtained on mobile phone screen；
Step 2：The top layer polarizer for taking step one to remove, is fabricated to polarising glass, the visible range of coloured image is only limited
In the dead astern of polarising glass；
Step 3：Polarising glass coordinates the random keyboard and touch-screen of mobile phone, you can as anti-peeping code input device, to reach
Prevent other people from spying on the purpose of trading password.
The preparation method of the polarising glass is：The top layer polarizer that step one is removed is cut into two circles, is attached to eye
On mirror holder, polarising glass is produced.
Beneficial effects of the present invention：
The preparation method for the anti-peeping code input device that the present invention is provided, using existing waste mobile phone screen, changes to it
Make, the polarizer of liquid crystal display screen of mobile phone top layer is removed, the screen now seen is white screen, by the top layer polarizer system of removal
It is made polarising glass, if it is desired to see the content on display clearly, then need user wearing polarized glasses, this function can be controlled effectively visually
Scope, reaches peep-proof effect；Mobile phone screen touch screen functionality is retained, can be directly defeated on screen with reference to random keyboard
Enter password, the physical keyboard that the payment POS machines that the general supermarket of contrast, market are used are carried, random keyboard can improve confidentiality,
Pay safer；Smart mobile phone network-connectable, preferably can be docked with payment system；All kinds of app of installation can be downloaded, with life
Loose joint rail, makes it more intelligent；The design the old mobile phone that is eliminated is carried out it is secondary utilize, cost but also is more not only greatly reduced
Meet environmental protection theory.
Embodiment
With reference to embodiment, the present invention is further elaborated.
A kind of preparation method of anti-peeping code input device, comprises the following steps：
Step one：Waste and old smart mobile phone is taken, the top layer polarizer of LCDs is removed, retains bottom polarizer so that
Uniform light intensity is obtained on mobile phone screen；
Step 2：The top layer polarizer for taking step one to remove, is fabricated to polarising glass, the visible range of coloured image is only limited
In the dead astern of polarising glass；
Step 3：Polarising glass coordinates the random keyboard and touch-screen of mobile phone, you can as anti-peeping code input device, to reach
Prevent other people from spying on the purpose of trading password.
The preparation method of the polarising glass is：The top layer polarizer that step one is removed is cut into two circles, is attached to eye
On mirror holder, polarising glass is produced.
LCD relies on polarized light piece and light in itself.Available light towards dissipating at random from all directions, and polarised light is then
There is the light wave of certain direction of vibration, light only parallel with polarizer could can hinder by polarized light piece, that is, polarized light piece
Disconnected all light not parallel with itself.There are two polarized light pieces in liquid crystal display, 1, incident polarization mating plate, remove and polarization
The not parallel light in mating plate polarization direction, 2, outgoing polarization mating plate, light quantity, shape are passed through by the deflection angle of liquid crystal torsion according to light
Into image.Only light has been torqued into itself matches with second polarized light piece polarization direction, and light is just able to penetrating for maximum.
LCD is exactly made up of the orthogonal polarizing filter of two such, so should in the case of normal no power
Block all light for attempting to penetrate.But, due to being filled with twisted liquid crystal between two filters, so projecting the in light
After one polarized light piece, it can be turned round and turn 90 degrees by liquid crystal molecule, finally be passed from second polarization mating plate.On the other hand, if
For liquid crystal plus a voltage, molecule can be rearranged and is substantially parallel again, light is no longer reversed, so just by second partially
The mating plate that shakes is blocked.
In a word, when incident polarizer and outgoing polarization piece polarization direction are into 90 degree of angles, liquid crystal power-up is hindered light
It is disconnected, it is not powered, project light.When incident polarizer is parallel with outgoing polarization piece, light will be powered up to liquid crystal to be projected, and be not added with
It is electric then be blocked light.
We make using above-mentioned liquid crystal display principle " anti-peeping code input device ", key technology is liquid
Two " polarizers " of crystal display screen " top layer " and " bottom " are separated, so that the visual range of downscaled images.
First：We retain the bottom polarizer of liquid crystal display screen of mobile phone, but remove top layer polarizer, so that in hand
Uniform light intensity is obtained on machine screen.Then, we make polarising glass, so that the visible range of coloured image be limited only within
The dead astern of glasses.Finally, " random keyboard " and " touch-screen " is coordinated, you can reaching prevents other people from spying on bank card business dealing password
Purpose." top layer " polarizer that this patent only needs to would sit idle for mobile phone is removed, and coordinate " polarising glass ", " touch screen functionality " with
" random keyboard " can be completed.
