Embodiment
Fig. 2 is the circuit diagram according to the portable electric device of one embodiment of the invention.With reference to Fig. 2, portable electric device 200 comprises a plurality of Touch Screen 210a～210c, screen control circuit 220 and CPU (central processing unit) 230.Wherein, screen control circuit 220 is electrically connected Touch Screen 210a～210c.CPU (central processing unit) 230 is electrically connected screen control circuit 220.
Further, screen control circuit 220 comprises a plurality of input port 221a～221c, multiplexer 222, controller 223, transmission interface 224 and clock generator 225.Wherein, input port 221a～221c is corresponding one by one with Touch Screen 210a～210c respectively, and is electrically connected with Touch Screen 210a～210c.Multiplexer 222 is electrically connected input port 221a～221c.In addition, multiplexer 222 can be chosen one from a plurality of input port 221a～221c, to export the signal that a certain input port was transmitted to controller 223.Moreover controller 223 is electrically connected multiplexer 222, transmission interface 224 and clock generator 225.
For making those skilled in the art can more understand the operation of portable electric device 200, Fig. 3 is the flow chart according to the portable electric device of one embodiment of the invention, below referring to the interactively of each member of Fig. 2 and Fig. 3 portable electric device 200.
As shown in step S310, at the beginning, screen control circuit 220 can be proofreaied and correct Touch Screen 210a～210c.After treating that Touch Screen 210a～210c all proofreaies and correct, as shown in step S321 and S322, the state being pressed with reference to Touch Screen 210a～210c, and determine whether by one of Touch Screen 210a～210c, produce touching signals and trigger pip.For instance, as shown in Figure 2, the state that Touch Screen 210a～210c all can be pressed with reference to itself, and determine whether to produce separately a touching signals and a trigger pip.Therefore,, if when Touch Screen 210a is pressed, Touch Screen 210a will produce touching signals SCT1 and trigger pip STR1.Relatively, if when Touch Screen 210b is pressed, Touch Screen 210b will produce touching signals SCT2 and trigger pip STR2.By that analogy, the generation of touching signals SCT3 and trigger pip STR3.
Moreover multiplexer 222 can be chosen one from input port 221a～221c, and the touching signals SCT that the input port of choosing is transmitted sends controller 223 to.For example: when Touch Screen, 210a is pressed, and input port 221a is when be selected, and touching signals SCT1 will be transferred into controller 223.In addition, the trigger pip STR that Touch Screen 210a～210c produces all can be transferred into clock generator 225.Thus, as shown in step S330, clock generator 225 can produce a clock signal clk with reference to trigger pip STR, and controller 223 operates with reference to clock signal clk with transmission interface 224.
It should be noted that controller 223 meeting foundation are in order to merge some set of Touch Screen 210a～210c.Thus, as shown in step S341 and S342, controller 223 defines the touch point of each Touch Screen 210a～210c with reference to a reference point, and converts touching signals SCT to a coordinate figure VAL under a set with reference to described reference point.For instance, Fig. 4 is the structural representation according to the Touch Screen of one embodiment of the invention, at this hypothesis portable electric device 200, Touch Screen 210a and 210b are only set, and the resolution of Touch Screen 210a and 210b is 480x800.In addition, the left side of Fig. 4 is the definition that controller 223 carries out each touch point of Touch Screen 210a and 210b in the situation that not setting up some set, the definition that the right-hand part of Fig. 4 carries out each touch point of Touch Screen 210a and 210b in the situation that setting up some set for controller 223.
As shown in Figure 4, do not setting up under some set, to be the touch point P11 of take separately respectively to be had and P21 define as benchmark for Touch Screen 210a and 210b.Therefore, concerning Touch Screen 210b, the touch point P21 that is positioned at its lower left is its reference point, therefore the coordinate figure of touch point P21 is (0,0).Relatively, be positioned at the top-right touch point P22 of Touch Screen 210b, its coordinate figure is (480,800).Yet when the touch point of Touch Screen 210a and 210b combines, Touch Screen 210a and 210b will all be take touch point P11 and be defined as benchmark.Therefore,, concerning Touch Screen 210b, the touch point P21 that is positioned at its lower left will be no longer its reference point, and the coordinate figure of touch point P21 will change to (480,0).Relatively, be positioned at the top-right touch point P22 of Touch Screen 210b, its coordinate figure will change to (960,800).
Thus, in the present embodiment, screen control circuit 220 can be controlled a plurality of Touch Screens.Relatively, with prior art in comparison, portable electric device 200 can be along with the reduction of screen control circuit 220 configuration quantity, and towards compact trend development, and has characteristic and the advantage of being convenient to carry.In addition,, along with the reduction of screen control circuit 220 configuration quantity, the complexity of portable electric device 200 operating systems also can relatively be lowered.
Continue referring to Fig. 2 and Fig. 3, about the interactively of 230 of the CPU (central processing unit) of screen control circuit 220 and rear end, will be described below.Concerning CPU (central processing unit) 230, it is to link up by transmission interface 224 and the controller 223 in screen control circuit 220.For fear of the operational mistake of CPU (central processing unit) 230, in step S351, the touching signals that input port 221a～221c can produce with reference to Touch Screen 210a～210c and produce look-at-me.For example: when input port 221a receives the touching signals SCT1 that Touch Screen 210a produces, input port 221a will produce look-at-me SIT.
In addition, in step S352 and S353, CPU (central processing unit) 230 can judge whether to receive look-at-me SIT, and in the situation that receiving look-at-me SIT, acquisition carrys out the coordinate figure VAL of self-controller 223.Thus, CPU (central processing unit) 230 is carried out corresponding operation with reference to coordinate figure VAL.Moreover as shown in step S360～S380, when Touch Screen 210a～210c is not all pressed, clock generator 225 will stop clocking CLK, so that controller 223 shut-down operations.In addition, CPU (central processing unit) 230 can transmit a reset signal RST to controller 223, so that controller 223 is reset by transmission interface 224.
It is worth mentioning that, the Touch Screen 210a～210c of the present embodiment can be for example the combination of resistance touch screen, capacitance touch control screen or above-mentioned Touch Screen.For instance, if when Touch Screen 210a is resistance touch screen, Touch Screen 210a can adopt the induction technology of four-wire type.Relatively, touching signals SCT1 is now the set of the signal that in Touch Screen 210a, 4 electrode X+, X-, Y+, Y-produce.Moreover the transmission interface 224 of the present embodiment can be for example inter-integrated circuit (inter integrated circuit, I2C) interface or Serial Peripheral Interface (SPI) (serial peripheral interface, SPI).Although the present embodiment has been enumerated the embodiment of Touch Screen and transmission interface, it is not in order to limit the present invention, and those skilled in the art can change according to design the embodiment of Touch Screen and transmission interface.
In sum, the present invention utilizes screen control circuit that the touch point of a plurality of Touch Screens is merged into some set.Thus, screen control circuit can define the touch point of each Touch Screen with reference to a reference point, and then a plurality of Touch Screens are merged into a Touch Screen.Thus, the present invention can control a plurality of Touch Screens by single screen control circuit, and then reduces the consumption of portable electric device hardware space and the complexity of operating system.
Although the present invention discloses as above with embodiment; but it is not in order to limit the present invention; technical field technician under any; without departing from the spirit and scope of the present invention; can change arbitrarily or be equal to replacement, therefore the scope that protection scope of the present invention should be defined with the application's claim is as the criterion.
