Description
Technical field
The present invention is relevant with touch technology, and especially relevant with technology in order to the noise resistivity that strengthens contactor control device.
Background technology
Along with science and technology is showing improvement or progress day by day, the operation interface of various electronic products is more and more hommization all.For example, see through Touch Screen, the user can directly make program, input message/literal/pattern with finger or pointer in on-screen options, saves the trouble of using other input media.In fact, Touch Screen normally is comprised of an induction panel and the display that is arranged at the induction panel rear.The position of touching on induction panel according to the user and the picture that presents of display at that time, electronic installation can be judged the meaning of this time touching, and carries out corresponding operating result.Existing touch technology roughly is divided into resistance-type, condenser type, induction, ultrasonic formula and several classes of optical profile type.Appearance formula (mutual-capacitance) touch technology has the advantage that can realize the multi-point touch scheme mutually, therefore is widely used in recent years in many products.
The induction panel of appearance formula touch control induction device comprises the electrode of making mainly with transparent conductive material mutually, and these electrodes interlock and are covered with whole induction panel.See also the induction installation vertical view shown in Fig. 1 (A), the electrode 12 that is parallel to directions X in this example is drive electrode (drive electrode) more, and the electrode 14 that is parallel to Y-direction is induction electrode (sense electrode) more.Above-mentioned two kinds of different electrodes consist of the matrix pattern (pattern) that comprises a plurality of units induction region.Shown in Fig. 1 (A), every row drive electrode 12 is connected to a driver 16 separately, and every hurdle induction electrode 14 is connected to a receiver 18 separately.Generally speaking, these drivers 16 can sequentially be sent the driving signal, and 18 of these receivers can continue to receive induced signal.
Fig. 1 (B) is the partial enlarged drawing of Fig. 1 (A), and Fig. 1 (C) is the front view of Fig. 1 (B).As previously mentioned, a unit induction region 20 is by drive electrode 12 and induction electrode 14 definition.In this example, drive electrode 12 and induction electrode 14 are arranged at and are parallel to each other and perpendicular to two Different Plane of Z direction.Because two electrodes are designed to have different current potentials, therefore there is the line of electric force 32 of some therebetween.When user's finger 30 during near unit induction region 20, because finger 30 has the character of a similar ground connection, the part line of electric force 32 that drive electrode 12 and induction electrode are 14 can be attracted by finger 30, causes the mutual capacity of 14 of drive electrode 12 and induction electrodes to reduce.The output signal that is connected to the receiver 18 of this induction electrode 14 can reflect this and hold mutually variable quantity.Send the position of the driver 16 that drives signal when occuring according to the position of this receiver 18 and touching, subsequent conditioning circuit can be judged the coordinate of touch points on the X/Y direction.
What must illustrate is to be subject to pointing 30 line of electric force that affect and mainly to be distributed in regional 22A and the 22B that indicates among Fig. 1 (B), namely two fringe regions of drive electrode 12 and the confluce of induction electrode 14 in vertical view.Because the cause of shielding effect, the most line of electric force in below, confluce of induction electrode 14 and drive electrode 12 can not be subject to pointing 30 too much influences.Easy speech, the line of electric force that above-mentioned mutual appearance variable quantity mainly comes from regional 22A and 22B changes.
In the prior art shown in Fig. 1 (A), drive electrode 12 is the identical strip electrode of width with induction electrode 14.Yet the electrode pattern of existing induction panel is not limited to this, and Fig. 2 (A) and Fig. 3 (A) are other two kinds of existing electrode patterns.In Fig. 2 (A), drive electrode 12 is wider than induction electrode 14.But, for each unit induction region among Fig. 2 (A), the zone that user's touching can affect electric force lines distribution is limited to two fringe regions of drive electrode 12 and induction electrode 14 confluces equally, such as regional 23A and the 23B that indicates among Fig. 2 (B).
In Fig. 3 (A), each drive electrode 12 and induction electrode 14 are respectively a rhombus.Fig. 3 (B) is the partial enlarged drawing of Fig. 3 (A).Adjacent driven electrode 12 in the same row links to each other with the bridge that is parallel to directions X; Adjacent induction electrode 14 in the same hurdle links to each other with the bridge that is parallel to Y-direction.Unit induction region 20 in this example is by two drive electrodes 12 and two induction electrode 14 definition.Unit induction region 20 in Fig. 3 (B) mainly is the touching impact that electric force lines distribution among the regional 24A-24D can be subject to the user.Can be found out that by Fig. 3 (B) regional 24A-24D roughly is equal to cornerwise nearby sphere of unit induction region 20.
For the degree of accuracy of touch-control to a certain degree is provided, unit induction region 20 areas among Fig. 1 (B), Fig. 2 (B) and Fig. 3 (B) are usually roughly the same, for example are all 5 millimeters of 5 millimeters *.Concerning single unit induction region, the mutual appearance variable quantity that the user causes is larger, more is not easy to be subject to noise, the position that subsequent conditioning circuit also more can correct interpretation touch points.Adopt in the electronic system of multi-point touch function at some at present, in order to increase mutual appearance variable quantity, to resist the noise that refers to that simultaneously action is introduced, the potential difference (PD) that drive electrode 12 and induction electrode are 14 is raised to tens volts more.Except the power consumption height, the shortcoming of this way is that interlock circuit all must have can bear high-tension characteristic, therefore causes the hardware cost of Touch Screen significantly to rise.
Summary of the invention
For addressing the above problem, the present invention proposes a kind of new mutual appearance formula touch control induction device.By suitably shape and the configuration of design driven electrode and induction electrode, in onesize unit induction region, can effectively comprise more zones that can be subject to user's touching impact, and then variable quantity is held in lifting mutually, the signal noise ratio of promotion feeling induction signal (signal to noise ratio, SNR) namely.Have good location accuracy and noise resisting ability according to mutual appearance formula touch control induction device of the present invention and electronic system.Compared to the prior art that adopts high potential difference, according to comparatively power saving of mutual appearance formula touch control induction device of the present invention, the hardware cost is also lower.
