Description
Technical field
The present invention is related to touch technology and especially related to the electrode pattern of self-tolerant touch control induction device.
Background technology
As science and technology is showing improvement or progress day by day, operation interface all more and more hommizations of various electronic products.For example, by touching
Control screen, user can directly with finger or stylus on the screen operation sequence, input message/word/pattern, eliminate the need for
The trouble of other input units.In fact, Touch Screen is typically by an induction panel and is arranged at the one of induction panel rear
Display forms.The position touched according to user on induction panel and the picture that display is presented at that time, electronics
Device can determine whether the meaning of this touching, and perform corresponding operating result.
Existing capacitance touching control technology can be divided into self-tolerant (self-capacitance) and mutual capacitance type (mutual-
Capacitance) two class.Compared with mutual-capacitive touch panel, self-capacitance type touch panel can be by the more simple individual layer electricity of processing procedure
Pole structure realizes, has the advantages that lower-cost, therefore is widely used in low-end electronic product.
Fig. 1 is a kind of electrode configuration of common self-capacitance type touch panel, multiple wide in induction region 100 and be similar to
The electrode (such as electrode 11~14) of right angled triangle is staggered up and down.In this example, each electrode is each attached to
One inductor (to keep drawing clear, only draws the first inductor 15 of connection electrode 11 and the second sense of connection electrode 13
Device 16 is answered as representative).User's touching can influence the magnetic line of force distribution of electrode perimeter, in turn result in the electricity that inductor detects
Capacitance changes.After testing result is provided to a controller (not illustrating) by these inductors, controller can judge according to this
The position that user touches occurs.
Other two kinds of existing electrode patterns are presented in Fig. 2 and Fig. 3.In fig. 2, the flat shape of each electrode is substantially square
Shape, and it is arranged as a matrix.In figure 3, the flat shape of each electrode be then comprising a central area with from the center
Four dendritic areas that domain is extended.It is proved by simulated experiment, the common shortcoming of three of the above electrode pattern is sensing
As a result the linearity is bad.For example, if imposing touching track as shown in Figure 4 A, obtained sense to the electrode in Fig. 3
Should result by for the irregular lines in Fig. 4 B, it is quite big with practical touch track difference.
The content of the invention
To solve the above problems, the present invention proposes a kind of new self-tolerant touch control induction device.By appropriately designed electrode
Shape and configuration, self-tolerant touch control induction device according to the present invention compared with the prior art have it is more good sensing result it is linear
Degree.
Itd is proposed a kind of self-tolerant touch control induction device according to the present invention, includes multiple induction electrodes.Each induced electricity
Pole respectively contains a central area and four elongated areas.Four elongated areas are to surround the central area to set and respectively connect
It is connected to the central area.The central area and four elongated areas generally comprise Yi " Swastika " pattern or Yi " Swastika " pattern.
It can be further understood on the advantages and spirit of the present invention by following detailed description and accompanying drawings.

Specific embodiment
A specific embodiment according to the present invention is a kind of self-tolerant touch control induction device, electrode shape and configuration mode
It is depicted in Fig. 5 A.It should be noted that a so-called word of the invention is that censure the invention that these embodiments are presented general herein
It reads, but it is covered scope and is not limited by these embodiments in itself.
Multiple induction electrodes (such as electrode 51,52) are included in this self-tolerant touch control induction device.In the plurality of induced electricity
In extremely, each induction electrode positioned at central area is surrounded by four other induction electrodes.Induction electrode 51 is presented in Fig. 5 B
Detail structure, as representative.Induction electrode 51 includes a central area 51A and four elongated area 51B.Four elongated areas
51B sets around central area 51A and is respectively connected to central area 51A.Central area 51A and four elongated area 51B are big
Cause to form Yi " Swastika " pattern.As shown in Figure 5 B, the turning point of each elongated area 51B includes a protruding portion 51C.Protruding portion 51C's
Flat shape is similar to a triangle, and extends from elongated area 51B away from the direction of central area 51A.It must say
Bright, the flat shape of each protruding portion 51C is not necessarily intended to as the isosceles triangle shown in Fig. 5 B.
Fig. 6 is the electrode pattern schematic diagram of the touch control induction device in another embodiment of the present invention.In this reality
Apply in example, the central area of each induction electrode generally comprises Yi " Swastika with four elongated areas " pattern.
In both the above embodiment, the induction region of each induction electrode all extends to the sensing of its adjacent induction electrode
The recess in region, and have staggeredly in positioning axial (X-axis, Y-axis).That is, each induction electrode by four its
He surrounds induction electrode, and all induction electrodes are interspersed in two positioning axial (X-axis, Y-axis).This electrode configuration
Mode can cause no matter position of touch where, user touch each inductor trigger testing result (that is, semaphore) all
It is more uniform, and then the comparatively ideal sensing result linearity can be provided.The experiment proved that if the electrode in Fig. 5 A is imposed such as Fig. 4 A
Shown touching track, obtained analogue inductive result will be for the irregular lines in Fig. 7.Compared to the induced junction in Fig. 4 B
Fruit, electrode configuration of the invention obviously can provide the sensing result for being closer to practical touch track.
As described above, the present invention proposes a kind of new self-tolerant touch control induction device.By the shape of appropriately designed electrode
And configuration, self-tolerant touch control induction device according to the present invention have the more good sensing result linearity compared with prior art.Value
It is noted that electrode pattern proposed by the invention is a true single layer structure, three-dimensional bridge structure need not be penetrated and come
Into, thus the complexity of design can be simplified, improve production dose rate.
Although the present invention is disclosed as above with preferred embodiment, however, it is not to limit the invention, any this field skill
Art personnel, without departing from the spirit and scope of the present invention, when can make a little modification and it is perfect, therefore the present invention protection model
It encloses to work as and is subject to what claims were defined.
