MSC280 forms interface, and MSC and BSC275 form interface, and BSC275 correspondingly controls BS270 with by forward link signals
It is sent to mobile terminal 1 00.
Based on above-mentioned mobile terminal hardware configuration and communication system, the inventive method each embodiment is proposed.
Present terminal touch-screen selects capacitive touch screen mostly.Capacitance touch screen is one piece of four layers of compound glass screen：Most
Outer layer is glassivation；The second layer is conductive layer, and it is metal oxide to scribble one layer of nano indium tin ITO, the ITO；3rd
Layer is nonconducting glass screen；Most interior the 4th layer is also conductive layer, scribbles ITO.4th layer is screen layer, plays shielding internal
The effect of electric signal.
The figure etched in second layer ITO conducting wires module and the 4th piece of ITO conducting wire module is mutually perpendicular to, can be with
They are regarded as the draw runner of X and Y-direction consecutive variations, as shown in figure 3, Fig. 3 is embodiment of the present invention touch-screen set feeler
The principle sketch of position.One draw runner can treat as drives line 20, and it is sense wire 30 that another draw runner is treated as.Due to X, Y frame
In different surfaces, its intersection forms a capacitive node 102 to structure.When drive signal is applied in drives line, the electricity in drives line
Lotus can be couple on intersecting sense wire by capacitive node, so that measurable on sense wire couple signal to electric capacity, such as
Electric current and/or voltage.If during without conductive body close to the intersecting capacitive node of drives line and sense wire, the electricity of capacitive node
Hold coupling and keep constant.If conductive body contacts touch-screen, such as finger contacts touch-screen, and electric current in drives line can be caused to believe
Number change, and then cause the electric capacity of capacitive node to couple and change, the electric capacity of change can cause another layer of sense wire again
Electric capacity coupling signal change.Capacitance sensing circuit perceives capacitance variations and the position of capacitive node by scanning sense wire
Put, and then reach the purpose to touch-screen contact positioning.
Based on the operation principle of above-mentioned touch-screen, the drives line of touch-screen is set with vertical row in following the embodiment of the present application
Put, i.e., consistent with terminal device longitudinal direction, the sense wire of touch-screen is set with horizontal line, i.e., with the horizontal direction one of terminal
Cause.
