Present embodiment has adopted resistive touch screen framework commonly used (to be called for short FG, be that film is to the glass framework), its upper strata (promptly assembling the surface of back to the user) is a touch layer 10, touch layer 10 adopts the mylar PET (being called ITO Film in the industry) of sputter ITO (being indium tin oxide), has certain flexibility and good deformation-recovery ability.
The lower floor of resistive touch screen framework is a basic unit 30, and basic unit 30 adopts the glass (being called ITO Glass in the industry) of sputter ITO (being indium tin oxide), and glass wherein generally adopts chemically reinforced glass, has suitable hardness.
One conductive layer 20 is set between touch layer 10 and the basic unit 30.Conductive layer 20 adopts a conducting film, and this conducting film has also comprised the interface 21 of touch-screen and flexible circuit board (FPC).
The principle of work of resistance type touch control screen is, between ITO Film and ITO Glass, feed the voltage of the three ten-day period of hot season, go to touch ITO Film formation depression by finger or pointer, the ITO Glass of lower floor is by the variation that touches and produce voltage then, transferring digital signals to via the A/D controller again does calculation process by computer and obtains (X, Y) shaft position, and then reach the order ground of location.
In the touch-screen of present embodiment, touch layer 10, conductive layer 20 are prior art with 30 threes' of basic unit material, mutual alignment and annexation etc., also do not have change in the utility model, repeat no more herein.
In the utility model, basic unit 30 is provided with conductive path 31 deviating from a side surface of conductive layer 20 (usually, in Zhi Hou the assembling procedure also be in the face of the electronic installation mainboard a side).Conductive path 31 is an electrical path that links up, and is arranged on the idle outside surface of basic unit 30.
Certainly, in other embodiment of the present utility model, also can adopt other job operations of the prior art, in basic unit 30, form conductive path 31.
More specifically, as shown in Figure 5, present embodiment has the design feature in a larger area visual window zone 11 in heart zone therein at touch-screen, conductive path 31 is designed to three-back-shaped distribution around visual window zone 11, can increase the length of conductive path 31 significantly, optimize its result of use.
The shape of conductive path 31 also can be done corresponding distribution according to the idle region shape or the area of basic unit's reality of different area, be aided with three-back-shaped, technological means such as bow font etc. simultaneously and increase its line length, the general equal functional requirement of satisfying as the radio built-in aerial.
One end of conductive path 31 also electrically connects with the antenna feed point 32 of touch-screen, so as in follow-up packaging technology by the radio receiver signal feedback point electric connection on the electronic installation mainboards such as mode such as metal clips and mobile phone, realize its function.
Further, as shown in Figure 6, in this concrete enforcement, the side surface that basic unit 30 deviates from conductive layer 20 is divided into the first area 33 corresponding with the visual window zone 11 of touch-screen 10, and first area 33 is with the second area 34 of outside surface.
After so dividing, on first area 33, be provided with an insulation course (not shown) earlier.Conductive path 31 is arranged in the second area 34.
And, in this concrete enforcement, the thickness of insulation course is identical with the thickness of conductive path 31, makes basic unit 30 deviate from a side surface of conductive layer 20 after being provided with conductive path 31 and insulation course, still have good flatness, be beneficial to the installation and the electrical requirement in later stage.
In other specific embodiments, also can control the thickness of insulation course or conductive path, make the thickness of insulation course be slightly larger than the thickness of conductive path, also can realize its function substantially.
The manufacturing process of touch-screen of the present utility model is below described:
As previously mentioned, and reference is shown in Figure 6, and touch-screen has comprised stacked successively touch layer 10, conductive layer 20 and basic unit 30 at least.
At first, the side surface that basic unit 30 is deviated from conductive layer 20 is divided into the first area 33 corresponding with the visual window zone 11 of touch-screen, and first area 33 is with the second area 34 of outside surface.
Thereafter, technologies such as use screen printing are printed dielectric film on first area 33, form an insulation course.The function of this insulation course is that the operation for following process conductive path 31 provides the good working condition.
Then, by magnetic control splash technology, form conductive path 31 in second area 34, conductive path 31 can be chromium, nickel or nickel-chrome material.
In concrete enforcement, the thickness of control conductive path 31 is identical with the thickness of insulation course, or is slightly less than the thickness of insulation course, so that the basic unit 30 that is provided with behind conductive path 31 and the dielectric film still keeps good flatness.
Key of the present utility model is to deviate from basic unit 30 to form a conductive path 31 as the radio built-in aerial on the side surface of conductive layer 20.
Because the printing in the visual window zone of touch-screen is generally finished on the ITO of touch-screen Film (being touch layer), and radio built-in aerial (being conductive path 31) is above the ITO Glass (being basic unit 30) attached to touch-screen and avoid the visual window zone, so the radio built-in aerial is hidden in the visual window zone shell in addition of electronic installation, the radio built-in aerial is not visible in the front of electronic installation.
Embodiment 2:
Referring to Fig. 4 and shown in Figure 7, present embodiment is the specific embodiment of electronic installation of the present utility model, and the electronic installation described in the present embodiment is the mobile phone of band touch-screen.
The touch-screen of band radio built-in aerial is installed in the handset front case with the attitude of touch layer 10 towards handset front case 1.
Basic unit's rear side of touch-screen is equipped with cell phone mainboard.Radio receiver signal feedback point (not shown) on the cell phone mainboard is connected with wireless antenna feed point 32 on the touch-screen shown in Fig. 5 by metal clips.So just finished being connected of radio built-in aerial and cell phone mainboard.
Because mobile phone inside also must be provided with antenna for mobile phone, for overcoming the interference of mobile phone signal and radio receiver signal as far as possible, near the generally preferred bonnet that antenna for mobile phone is arranged on mobile phone.Owing to used the touch-screen that has the radio built-in aerial of the present utility model, the radio built-in aerial is arranged on the position near the mobile phone protecgulum as much as possible, therefore form the spacing of antenna for mobile phone and radio antenna with regard to the thickness space of having utilized mobile phone as much as possible, make mobile phone have more excellent technique effect in use.
Aforementioned electronic includes but not limited to mobile phone, portable electronic device PMP (portable multimedia player), multifunction game player PSP (PlayStation Portable), personal digital assistant PDA portable electron devices such as (Personal Digital Assistant).
More than though embodiment of the present utility model has been described, it will be understood by those of skill in the art that these only illustrate, protection domain of the present utility model is limited by appended claims.Those skilled in the art can make numerous variations or modification to these embodiments under the prerequisite that does not deviate from principle of the present utility model and essence, but these changes and modification all fall into protection domain of the present utility model.
