It is beneath to coordinate appended schema elaborate by specific embodiment, when the purpose, the skill that are easier to understand the present invention
Art content, feature and its it is reached the effect of.
Brief description of the drawings
Fig. 1 is the structural representation of touch sensor of being commonly seen for one.
Fig. 2 is for the structural representation according to the height of embodiment of the present invention parsing touch sensing device.
The realization, functional characteristics and advantage of the object of the invention will be described further referring to the drawings in conjunction with the embodiments.
Embodiment
Present disclosure explanation is related to above, with following embodiment is demonstrated with explaining essence of the invention
God and principle, and provide the present invention patent claim further explain.Feature for the present invention, implementation and work(
Effect, hereby coordinates schema to make preferred embodiment detailed description as follows.
In order to effectively lift the signal analytic ability of existing touch sensor, the present invention be directed to this target propose it is a kind of compared with
Good improved device, it is for a high parsing touch sensing device.Wherein, in order to be able to technology of the present invention is better understood
Content, also referring to the schematic diagram of structure shown in Fig. 1 and Fig. 2, the present invention will carry out detailed be described as follows accordingly.
First, as shown in figure 1, it is the structural representation of touch sensor of being commonly seen for one.As illustrated, a ultrasonic group
Part 10 is, to be detected to tested object 20, and to provide sensing result, wherein, it is to make with multiple in ultrasonic component 10
Sensing unit for sending and receiving signal (as shown by arrows), to be detected to tested object 20.Due to ultrasonic group
The operating principle of part 10 mainly by one probe launches sound wave, encounter tested object 20 interface 21 produce bounce-back ripple, then by
Probe is detected, you can learn the relative position and sensing results of interface and probe.The technology of this some actually section now
Person known to skill, and the simultaneously invention emphasis of non-invention, therefore with regard to the thin portion technology contents of this ultrasonic assembly portion point, the present invention is simultaneously
Without repeating.
Afterwards, a cushion (buffer) 30 is disposed on the surface of ultrasonic component 10, in one embodiment, cushion
30 material for example can be organic material, inorganic material or the hybrid material (example being mixed with organic material and inorganic material
Such as：Dimethyl silicone polymer, Polydimethylsiloxane, PDMS).As shown in figure 1, putting down due to cushion 30 and non-fully
The material of sliding (smooth), therefore with that may have asking for surface roughness (roughness) on the interface 21 of tested object 20
Topic, therefore, the present invention is to be provided with one on this interface 21 to fill and lead up layer 40, and its structure is referred to shown in Fig. 2.
As shown in Fig. 2 the side for filling and leading up layer 40 be have a smooth surface 41, also, fill and lead up layer 40 be disposed on buffering
On the surface of layer 30, to manifest the smooth surface 41 simultaneously.Therefore according to embodiments of the present invention, fill and lead up layer 40 be can profit
Tested object 20 is contacted with this smooth surface 41, to reduce the table between the interface 21 of tested object 20 using smooth surface 41
Surface roughness.In general, after the surface roughness of contact interface is improved, then commonly seeing dry caused by surface roughness
Disturb and noise can effectively be prevented, then the present invention thereby can further lift the sensing precision of sensor.It is worth saying
It is bright, due to the present invention mainly use provide this have smooth surface 41 fill and lead up layer 40 lifted touch sensing device it
Signal analytic ability, therefore the numerical value such as the relevant material that this fills and leads up layer 40, thickness and surface roughness, then be all that the present invention is necessary
Design focal point that is kind plus considering.
Specifically, according to embodiments of the present invention, filling and leading up the material selection of layer 40 for example can be：It is organic material, inorganic
Material or the hybrid material that is mixed with organic material and inorganic material are (for example：Dimethyl silicone polymer,
Polydimethylsiloxane, PDMS), as shown in Fig. 2 its thickness T have to be larger than 3 microns (μm).As for, fill and lead up layer 40 it
Acoustic reactance value (acoustic impedance) then should be greater than 1.2 * seconds/rice of newton3, surface pencil hardness (surface pencil
Hardness 3H need to) be more than.In addition, according to embodiments of the present invention, the surface roughness for filling and leading up layer 40 more should be greater than delaying
The surface roughness of layer 30 is rushed, for example, need to be less than or equal to by filling and leading up the surface roughness of layer 40 by 10 microns, as cushion 30
Surface roughness be then greater than or equal to 3 microns.
Still further, in order to remove the interference between tested object 20 caused by surface roughness, this hair completely
Layer 40 is filled and led up selected by bright, its surface roughness more can be compensated further through a software, for example：Directly by surface
Roughness as background value deduct, then using the method, also can effectively by it is known because surface roughness and caused by interference and
Noise is removed completely.For example, the signal intensity received by touch sensing device can be by deduction roughness (i.e. background value)
Integral area represent, when carry out quantitative analysis when, you can effectively by originally because disturbing and making an uproar formed by surface roughness
Sound is removed completely, further preferably realizes the goal of the invention of the present invention.
Therefore in summary, disclosed herein height parsing touch sensing device be for one kind it is novel and not seen before
Design, it is that using one there is smooth surface to fill and lead up layer, to be contacted using this specific layer of filling and leading up with tested object,
Thereby improve the surface roughness on contact interface.Wherein, because the interference caused by surface roughness and noise can have
Effect ground prevented, therefore disclosed herein touch sensing device naturally have preferably signal analytic ability with perceive benefit.
For another aspect, according to disclosed herein height parse touch sensing device, this sensing device further not only can pin
Improvement is carried out to existing touch sensor outer with application, more can further be used for the solution of future technology robot finger touch
Analysis ability, all can using the present invention, therefore compared to known techniques, disclosed herein touch sensing device, it is clear that with compared with
Good sensing benefit and analytic ability, it is real that there is splendid industry development, in the potentiality of development, not only virtually to be carried with wide
The category that the high present invention can be applied, further promotes its industrial applicability.
Therefore, the purpose and effect of the obvious present invention are to be substantially better than prior art, and disclosed herein skill
Art feature, Method means are with being to be significantly different than current programme the effect of reaching, and non-in fact is that those skilled in the art can be easily
Complete winner, therefore possessing has patent requirement.
Many embodiments described above are only technological thought and features to illustrate the invention, and its purpose makes to be familiar with this
The personage of skill can understand the content of the present invention and implement according to this, when can not with the restriction present invention the scope of the claims, i.e.,
Generally the equivalent change made according to disclosed spirit or modification, should cover in the scope of the claims of the present invention.
