Below with reference to Fig. 1 to Fig. 5, the capacitance touch screen 1000 according to the individual layer of the embodiment of the present invention is described.
As shown in Figure 1, multiple driver unit 100 is comprised according to the first conductive array of the capacitance touch screen 1000 of the individual layer of the embodiment of the present invention, second conductive array comprises multiple receiving-member 200, and each receiving-member 200 comprises body 210 and Received signal strength enhanced portion 220.In one embodiment of the invention, multiple driver unit 100 is set parallel to each other, and multiple receiving-member is set parallel to each other.

Driver unit 100 disconnects in the first conductive array and the second conductive array intersection to form multiple driver unit section, and connected driver unit section is one another in series electrical connection.Adjacent driver unit section is connected by wire jumper 400.Between wire jumper 400 and the second conductive array, be provided with insulation course, thus make driver unit 100 and receiving-member 200 electrical isolation.
In an example of the present invention, wire jumper 400 can be metal jumper, such as carbon film wire jumper.
The space formed between multiple driver unit section is formed in the body 210 of the receiving-member being suitable for accommodation Received signal strength enhanced portion 220 and being formed with Received signal strength enhanced portion 220 at least partially.
As shown in Figure 1, each driver unit section is configured to rhombus, and each Received signal strength enhanced portion 220 has rhombus outline, and rhombus outline is suitable for the space that formed around multiple driver unit sections of the surrounding of described Received signal strength enhanced portion 220.Be understandable that, the shape of driver unit section is not limited thereto, and also can be other shapes, such as circular, oval or trapezoidal etc.But it should be noted that, the concrete structure of above-mentioned driver unit 100 is for exemplary purposes, instead of in order to limit the scope of the invention.
Multiple driver unit 100 provides pumping signal to multiple receiving-member 200 in turn, and in other words, at one time in section, multiple receiving-member 200 receives the pumping signal provided by same driver unit 100.Thus, when object touches capacitance touch screen, can the coordinate of high-precision locking touch point.
As shown in Figure 2, Received signal strength enhanced portion 220 comprises multiple first cantilever designs extended along the direction away from described receiving-member body 210 from described receiving-member body 210.In an example of the present invention, the first cantilever design can be strip.

In an example of the present invention, multiple 3rd cantilever portion 130 is mutually the same along the direction length away from vertical cantilever portion 120.
Be understandable that, the length of multiple 3rd cantilever portion 130 also can be different.As shown in Figure 3, in both sides vertically protruding two group of the 3rd cantilever portion 130 along vertical cantilever portion 120 symmetry in vertical cantilever portion 120.Often organize the 3rd cantilever portion 130 and comprise the 5th cantilever 130a, the 6th cantilever 130b, the 7th cantilever 130c and the 8th cantilever 130d.In an example of the present invention, the 5th cantilever 130a, the 6th cantilever 130b, the 7th cantilever 130c and the 8th cantilever 130d is strip and size is different.Thus, by there is the pumping signal enhanced portion of said structure, thus the ability that driver unit 100 provides pumping signal is added.But it should be noted that, the concrete structure of above-mentioned pumping signal enhanced portion is for exemplary purposes, instead of in order to limit the scope of the invention.
The driver unit 100 of structure shown in Fig. 3 and receiving-member 200 are carried out capacitance touch screen 1000 shown in slotting formation Fig. 4.Adopt the capacitance touch screen 1000 shown in Fig. 4, because all there is better coupling in the direction (longitudinal direction in Fig. 4) of the first conductive array and the direction (transverse direction in Fig. 4) of the second conductive array, the direct capacitance of the first conductive array and the second conductive array and the capacitance change of touch front and back more greatly, thus can reduce the requirement of hardware detecting circuit.
Individual layer capacitance touch screen, relative to double-layer capacitive touch screen, owing to the first conductive array and the second conductive array being placed at grade, reduces the volume of capacitance touch screen, and enhances the receiving ability of signal, and saved cost.
The location of capacitance to touch point coordinate detected for receiving-member Rx2 is below described.
As shown in Figure 5, capacitance touch screen 1000 mutual capacitance value is under normal circumstances 10pf (pico farad), driver unit Tx1, and when Tx2, Tx3, Tx4 send pumping signal in turn, receiving-member Rx2 end can detect 9pf, the capacitance of 6pf, 5pf, 8pf.When the touch-sensitive area having conductive body A (such as pointing) close to capacitance touch screen 1000, the electric charge that driver unit 100 senses becomes many, the electric charge that receiving-member 200 senses diminishes, thus can by the coordinate setting of conductive body between driver unit Tx2 and driver unit Tx3, and in the coordinate points of driver unit Tx3.
According to the capacitance touch screen of the embodiment of the present invention, by constructing Received signal strength enhanced portion on the body of the receiving-member of the second conductive array, add the area that the second conductive array receives pumping signal, thus add the ability that receiving-member receives pumping signal, add the surveyed area of the change of the mutual capacitance of detection first conductive array and the second conductive array.Further, independent conductor portion is equivalent to the distance furthered between driver unit and receiving-member, makes the mutual capacitance variable quantity between driver unit with receiving-member increase and become one to stablize accurate linear change, is convenient to detect, improves the precision judged.When there being conductive body to touch capacitance touch screen, the existence due to independent conductor portion can cause the change of the quantity of electric charge of the first conductive array and the second conductive array, utilizes the change of this quantity of electric charge to be convenient to locate the coordinate of touch point.In the manufacture course of products of reality, production cost can be reduced to a certain extent, enhance product performance.
By adjusting the value that can adjust mutual capacitance to the spacing of the degree of depth of inserting and the first conductive array, the second conductive array and independent conductor of the first conductive array and the second conductive array, and the linearity can be adjusted by adjustment driver unit and receiving-member length that is middle and edge, the precision of coordinate setting can be improved.
Below with reference to Fig. 6, the contactor control device according to the embodiment of the present invention is described.
