Compared with the prior art, the method can effectively realize functions required by a novel resistance-type touch screen, so that full touch of a flat screen mobile phone becomes true and the overall aesthetic perception and the brand new using experience of the mobile phone are enhanced greatly.
Description
Technical field
The present invention relates to a kind of collocation method of communication link, especially relate to a kind of collocation method of touch-screen circuit.
Background technology
Along with the development of touch screen (LTP) technology, touch screen functionality and outward appearance are all perfect further.The full frame touch of LTP progressively replaces original button keyboard, for the design of complete machine provides very big space.But traditional LTP line design just from the wiring of simple and mechanical touch-screen (Touch Panel) four limits, can not satisfy the demand of technical development, and be easy to cause Touch Panel electrical property bad.
Summary of the invention
Purpose of the present invention is exactly to provide a kind of realization touch function for the defective that overcomes above-mentioned prior art existence, improves the collocation method of the touch-screen circuit of mobile phone aesthetic degree.
Purpose of the present invention can be achieved through the following technical solutions:
A kind of collocation method of touch-screen circuit is characterized in that, this method for designing is controlled touch-screen by the reach the standard grade silver slurry cabling of the silver slurry cabling of circuit and the circuit that rolls off the production line of design.
The silver slurry line of the described circuit of reaching the standard grade places along Y direction in the insulator of touch-screen both sides, adopts the whole conducting film of reaching the standard grade to connect the horizontal component of electric field and silver slurry line of membrane keyboard again.
It is straight line that the described circuit that rolls off the production line adopts the centre of silver slurry line, the cabling mode of bending two ends, and the inner edge of silver slurry line is a straight line.
When there was the key area in the described circuit that rolls off the production line in the bottom, silver slurry line was drawn branch's silver slurry line and is connected button along the X-direction cabling in the centre of silver slurry line, and the key area is provided with conducting film.
The described silver slurry line width at narrow place is not less than 0.8mm.
Described Y-axis is a vertical direction.
Described X-axis is a horizontal direction.
The conducting film of described key area is separated setting with the conducting film of reaching the standard grade.
Compared with prior art, the present invention can effectively handle the realization of novel resistive touch screen requirement function, makes pure flat mobile phone realize fully putting to touch entirely becoming a reality, and has improved the aesthetic degree of mobile phone integral body and the complete new experience of use greatly.

Embodiment
The present invention is described in detail below in conjunction with the drawings and specific embodiments.
A kind of operational zone and function key area are the touch-screen (LTP) of one, the principle that realizes its function is: the marking current that keypad touched is derived by the silver slurry lead on next door, this root silver slurry has double action, being respectively two operating areas responds, guarantee to have stable and continuous electric field, the conducting film in two zones need couple together, and also wants reasonable Arrangement silver slurry lead thickness and bending radian simultaneously.
Reach the standard grade circuit silver slurry line 2 cabling as shown in Figure 1, employings electric field is an X-direction, promptly silver slurry line parallel is in Y-axis is put into the insulation of phone housing 2 both sides, the membrane keyboard horizontal component of electric field is connected with the silver-colored lead of starching.For the full frame touch of real embodiment, the conducting film of reaching the standard grade adopts whole effect, roll off the production line silver slurry line 2 cabling as shown in Figure 2, size according to the H value is arranged cabling, if H value hour and L place to the lower convexity radian again than greatly the time, Y-axis lower end silver slurry line be difficult to can TP lower end insulating regions in, need adopt straight line in the middle of the silver slurry in this case, the cabling mode that two ends are crooked slightly.When cabling, need make the straight line that is that silver slurry line inner edge may be many as far as possible, can guarantee on the straight line that is parallel to X-axis arbitrarily to be an approximate equipotential line.Silver slurry line 2 outer side edges are that straight line or radian limit directly do not influence linearity, but the width of silver slurry line 2 is determining resistance, and the narrowest place width should be not less than 0.8mm.At the knuckle of both sides circular arc, the crooked tendency of silver slurry line 2 is determining the size of the corresponding projection line A of form institute, and A value is more little, test linear setting-out be regularity be offset more little, good more to the electrical property of LTP integral body.
The LTP method for designing that a kind of operational zone and functional areas separate, reach the standard grade circuit silver slurry line 2 cabling as shown in Figure 3, the method for designing special feature of this kind is mainly in the disconnection of conducting film, this kind product is more special, is that the subregion has touch function in the TP bottom, and the ITO conducting film of key area wants effective collinearity test zone to separate, otherwise can influence the equal regional internal drop difference of electroplax, the electric field strong and weak difference, equipotential line is disorderly to distribute, and makes the linear setting-out skew of test.The circuit cabling that rolls off the production line is shown in Figure 4: be parallel to the X-direction cabling, draw branch's silver slurry line at the middle part of silver slurry line 2, and then draw two buttons, branch's silver slurry enters total silver-colored slurry place and disconnects, thereby can not form short circuit, otherwise the button place will not have effect.The electroconductive ITO layer that rolls off the production line must be integral body.It is to contact the purpose that reaches conducting by the ITO bus effectively with the silver slurry that the conduction of key area connects, and as can be seen, the conducting film of the key area and the range of linearity does not link to each other, separates, so that the touch area increases impedance, is easy to software and distinguishes signal.
In addition, also have a kind of cabling mode: the slit that a thicker silver slurry line 2 is parallel to two conducting films is to draw the mode of each push button signalling, and as shown in Figure 5, the outlet of this mode needs matching with mobile phone touch-screen Control Software to reach desirable purpose.
