Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
The present invention is a kind of protection pad pasting with contact forwarding function, structure as shown in Figure 1, comprise screen protector membrane body 1, the thickness of screen protector membrane body 1 is 0.1-0.5mm, the material of screen protector membrane body 1 is PET or tempered glass, material has high light transmittance and wearing quality, and high-flatness, a pair through hole 5 is had below screen protector membrane body 1, the center section of screen protector membrane body 1 is the corresponding display screen viewing area 3 matched with mobile phone screen, the top of corresponding display screen viewing area 3 is the touch point A9 corresponding with screen virtual button and touch point B10, as shown in Figure 2, the one side that touch point A9 and touch point B10 and screen fit all is coated with one deck ITO transparent conductive film 2, and ITO transparent conductive film 2 extends to through hole 5 along both sides, long limit, display screen viewing area 3 formation path, the hole wall of through hole 5 and around in, outer both side surface is also coated with one deck conductive metal film 4, conductive metal film 4 and ITO transparent conductive film 2 is followed successively by between through hole 5 peripheral inner surfaces and screen, conductive metal film 4 and ITO transparent conductive film 2 mutual conduction, the ITO transparent conductive film distributed around the both sides, long limit of corresponding display screen viewing area 3 can also substitute with conductive metal film.
There is a method for making for the protection pad pasting of contact forwarding function, specifically implement according to following steps:
Step 1, according to the concrete shape of mobile phone faceplate and the position of perforate and shape, and the materials processing screen protector membrane body 1 required;
Step 2, adopt existing flexible circuit board technology, conductive metal film 4 on the hole wall of the through hole 5 of screen protector membrane body 1 in step 1 and around inside and outside plated surface;
Step 3, be covered with one deck protector film outer surface release film 6 again in the outside surface of the screen protector membrane body 1 of step 2;
Step 4, by the whole inside surface of existing physical gas phase deposition technology by ITO sputtering of materials screen protector membrane body 1 in step 3, form one deck ITO transparent conductive film, so-called physical gas phase deposition technology specifically refers to adopt magnetron sputtered deposition technology or evaporation coating techniques;
On the ITO transparent conductive film 2 on the hole wall of step 5, through hole 5 in step 4, screen protector membrane body 1 inside surface through hole 5 peripheral circular region, long limit, corresponding display screen viewing area 3 and touch point A9 and touch point B10 plate layer of silicon dioxide restraining barrier;
Step 6, method by acid etching technique, retain the region covered by silicon dioxide blocking layer in step 5, then etched away by the ito thin film beyond these regions, etch the shape of ITO transparent conductive film 2;
Step 7, the screen protector membrane body 1 in step 6 to be cleaned, remove impurity;
Step 8, screen protector membrane body 1 inside surface with make-up machine one deck AB glue 7 closely overlayed in described step 7, the one side that AB glue 7 is attached with OCA optical cement fits with screen protector membrane body 1 inside surface;
The one side that step 9, AB glue 7 are in step 8 attached with silica gel is covered with one deck protection pad pasting inside surface release film 8 identical with screen protector membrane body 1 shape size again, obtains final product.
The present invention is before use contact transfer pad pasting, first by mobile phone screen wiped clean, then the protection pad pasting inside surface release film 8 of screen protector membrane body 1 inside surface is opened, screen protector membrane body 1 inside surface is also alignd with it towards mobile phone screen front, slowly be bonded on screen, touch point A9 shown in Fig. 1 and touch point B10 region alignment on the top of screen virtual key position and pad pasting will be ensured simultaneously, finally tear protection pad pasting inside surface release film 8, in operating handset process, when needing virtual return key or the virtual menu key clicking the top of screen upper left corner or the upper right corner, only need click the through hole 5 in Mobile telephone front panel screen protector membrane body 1 lower left angle or the lower right corner respectively.
Principle of work of the present invention is, because conductive metal film 4 and ITO transparent conductive film 2 are conductor, when finger contacts with the conductive metal film 4 around through hole 5, finger and conductive metal film 4 and ITO transparent conductive film 2 equipotential, its circuit effect and virtual key region touch point A9 identical with during the B10 of touch point (ignoring the resistance of conductive film self) in the direct touch screen of finger when so finger touch conductive metal film 4 contacts, so during conductive metal film 4 below finger touch screen around through hole 5, touch point A9 and B10 region, touch point ITO transparent conductive film 2 form coupling capacitance with the ITO transparent conductive film of mobile phone capacitive touch screen interlayer, the weak current produced by human body electric field will flow out from touch point A9 and B10 region, touch point, so the actual contact that touch-screen receives is touch point A9 and B10 region, touch point, system finally makes the response touching touch point A9 and B10 region, touch point virtual key.Core of the present invention to be plated in another pole plate of the ITO transparent conductive film (touch point A in Fig. 1 and touch point B region) with certain area corresponding with virtual key position on display screen as the electric capacity corresponding with the interlayer transparent conductive film in the capacitive touch screen on mobile phone on screen protector membrane body 1 surface; then the conductive film in touch point A9 and B10 region, touch point is connected to mobile phone faceplate bottom position beyond on-screen display (osd) area by an elongated ITO transparent conductive film 2 as wire, is difficult to the virtual key of the top of screen touched to avoid finger touch.
The present invention protects pad pasting by the mobile phone that subsides one are special; transfer to pointing the virtual key correspondence position contact being difficult to touch during user's single hand operation of mobile phone on the position that below mobile phone, beyond screen, finger can touch easily, and this is the function not available for existing sticking film for mobile phone.
If consideration problem of appearance; also other cabling mode can be used; can replace with common conductive metals film when the elongated ito thin film part playing wire effect is beyond on-screen display (osd) area; cabling mode can change into and passing through from protection pad pasting side; then be transitioned into pad pasting outside surface, thus avoid using through hole to reduce manufacturing process and to cut down finished cost.
