Embodiment
(first embodiment)
See also Fig. 2 A and Fig. 2 B, Fig. 2 A is the exploded view of the contactor control device of the utility model first embodiment, and Fig. 2 B is the fragmentary cross-sectional view of Fig. 2 A.Contactor control device 1 of the present utility model comprises a light guide 10, a plurality of light emitting module 12 and a plurality of touch sensing module 14, and described a plurality of light emitting modules 12 and described a plurality of touch sensing module 14 can be arranged on the same substrate 16.Superimposed on substrate 16 time when light guide 10, the light that light emitting module 12 is produced can enter in the light guide 10 smoothly.Below do more detailed description with regard to each element of contactor control device 1 respectively.
Has at least one external series gap 102 on the light guide 10, in order to light guide 10 is distinguished to constitute a plurality of leaded light blocks 104.In other words, any two 104 of adjacent light guide zone pieces in the light guide 10 have an external series gap 102 at least.Each leaded light block 104 has incidence surface 104a, exiting surface 104b and bottom surface 104c respectively.At this, light guide 10 also has a plurality of grooves 106, and each groove 106 is in order to the light emitting module 12 of a ccontaining correspondence, and superimposed on substrate 16 time when light guide 10, each light emitting module 12 can be placed among external series gap 102 or the groove 106.
Close light emitting module 12 of incidence surface 104a and the light that light emitting module 12 is produced import leaded light block 104, exiting surface 104b is in connection with incidence surface 104a and have astigmatic patterned layer 104d, and astigmatic patterned layer 104d derives in the leaded light block 104 in order to the light that light emitting module 12 is produced.On practice, light guide 10 is a kind of flat light guide structure, exiting surface 104b and bottom surface 104c are respectively the last lower plane of described dull and stereotyped light guide structure, and exiting surface 104b and bottom surface 104c are parallel to each other haply, and incidence surface 104a is the side of described dull and stereotyped light guide structure between last lower plane, so incidence surface 104a can be respectively in connection with exiting surface 104b and bottom surface 104c.At this, the position (external series gap 102 or groove 106) that incidence surface 104a places according to light emitting module 12 is formed on by external series gap 102 or the groove 106 and is designed to be suitable for receive the light that light emitting module 12 produces, make light can enter each the leaded light block 104 in the light guide 10 smoothly, and light can be transmitted by the total reflection mode in light guide 10.
By on the other hand, the leaded light block 104 of each light emitting module 12, corresponding configuration can constitute single luminous touch control unit (as the luminous touch control unit 3 of Fig. 6) with the touch sensing module 14 of corresponding configuration, and each luminous touch control unit 3 can be by each self-corresponding touch sensing module 14 independently to control the luminous of its corresponding light emitting module 12.In this embodiment, though separate with external series gap 102 on the light guide 10 and form each leaded light block 104, but the leaded light block 104 of each luminous touch control unit 3 still has at least part to link to each other with the leaded light block 104 of adjacent luminous touch control unit 3, and make light guide 10 still be single sheet, be placed on the substrate 16 and aim at separately touch sensing module 14 one by one and in manufacture process, directly be located easily with one step.
On the other hand, astigmatic patterned layer 104d on the exiting surface 104b can be an ink design layer, a sand blasting pattern layer or a printing net-point patterned layer, in order to change the total reflection condition in the corresponding leaded light block 104, make light to penetrate out leaded light block 104 from exiting surface 104b.On practice, the utility model does not limit the production method of astigmatic patterned layer 104d, and the area coverage of astigmatic patterned layer 104d on exiting surface 104b can be decided in its sole discretion by the user.
For instance, a chart board 20 more can be placed in light guide 10 tops, and that the size dimension of light guide 10, chart board 20 and substrate 16 is roughly is consistent, makes contactor control device 1 outer surface behind the storehouse present smooth shape.At this, chart board 20 has a transmission region 202 at least and presents a symbol pattern, if the symbol pattern of desire performance is bigger, the area coverage of then astigmatic patterned layer 104d on exiting surface 104b should correspondingly increase, the light that makes light emitting module 12 produce can penetrate by the transmission region 202 on chart board 20 via exiting surface 104b, and then shows described symbol pattern.In addition, chart board 20 can be a pattern adhesive tape (pattern tape), therefore has very narrow thickness (for example being 0.2mm), is pasted on the light guide 10 and can directly it be sticked together face.
Note that external series gap 102 can be used for separating the light in the two adjacent light guide zone pieces 104.Particularly, external series gap 102 can be considered a kind of air dielectric and refractive index approximates 1, and light guide 10 is to be used for guiding light to advance, thereby the refractive index of light guide 10 is usually much larger than 1.That is to say, when the arbitrary leaded light block in the light guide 10 104 is passed to external series gap 102 with light, be equivalent to enter optically thinner medium that light can depart from the normal refraction of exit facet from optically denser medium.Therefore, under the situation with external series gap 102, the light that penetrates out from leaded light block 104 can reflect away at exit facet towards periphery, very is not easy in the adjacent leaded light block 104 of the level of entering.Therefore, (with concrete instance, the width of external series gap 102 can be 3~5mm) to the external series gap 102 that the utility model can be by proper width, effectively isolates the light in each leaded light block 104.
Certainly the utility model does not limit the shape of external series gap 102 at this, as long as light guide 10 can be arranged in pairs or groups mutually with external series gap 102, make the light in the per two adjacent light guide zone pieces 104 can not interfere with each other, be spiritual place of the present utility model, can do suitable variation in this technical field person.
Please continue referring to Fig. 2 A and Fig. 2 B, light emitting module 12 major functions are to produce light, make each light emitting module 12 pairing leaded light block 104 to give out light and are discovered by the user.On practice, the light emitting module 12 that is arranged in any two adjacent light guide zone pieces 104 can be each other back to setting, and the relative distance of each light emitting module 12 on substrate 16 should zoom out as far as possible.At this, light emitting module 12 can be light-emitting diode or other suitable light-emitting component, and the utility model is not limited at this.For instance, light emitting module 12 can be made up of a plurality of light-emitting diodes, and each light-emitting diode can send the light of different wave length, and light emitting module 12 also can be selected single arbitrarily or make up a plurality of light-emitting diodes to produce the light of specified wavelength.
Described a plurality of touch sensing module 14 contacts the bottom surface 104c of light guide 10 respectively, and each touch sensing module 14 corresponding one of them leaded light block 104 that is to say that all there is a touch sensing module 14 any leaded light block 104 below.When the leaded light block 104 of touch sensing module 14 sensing correspondences is subjected to touching, export a drive signal according to this with control light emitting module 12.At this, touch sensing module 14 can comprise touching sensor conductor and touching sensing element (will in following detailed description) again.But whether the leaded light block 104 of touching sensor conductor sensing correspondence is touched by an object, and the touching sensing element can detect the equivalent capacitance value variable quantity of touching sensor conductor.
Specifically, see also Fig. 3, it is the operating principle schematic diagram of the touch sensing module of embodiment of the present utility model.As shown in Figure 3, each touch sensing module 14 has a touching sensor conductor 142 and a touching sensing element 144.On practice, described touching sensing element 144 can be incorporated in the control chip 146, when the leaded light block 104 of correspondence is subjected to touching, touching sensing element 144 can be according to the equivalent capacitance value variable quantity that detects touching sensor conductor 142, output drive signal is to light emitting module 12, with the lighting mode of decision light emitting module 12.In addition, control chip 146 more can be integrated the touching sensing element 144 of each touch sensing module 14 in the contactor control device 1, when different leaded light blocks 104 is subjected to touching, control chip 146 can be wanted corresponding which light emitting module 12 that drives to judge by detecting inner touching sensing element 144.With this, the use that the control chip of sharing 146 can be saved circuit element.
Angle from practical operation, if chart board 20 is placed in light guide 10 tops, when the user can touch symbol pattern on the chart board 20, touch sensing module 14 judges according to an equivalent capacitance variation amount of chart board 20, leaded light block 104 and other peripheral element whether leaded light block 104 is touched.When the result of described judgement showed that leaded light block 104 is touched, corresponding touch sensing module 14 output drive signals were to light emitting module 12, whether produced the wave-length coverage that light or control light emitting module 12 change the light that is produced with control light emitting module 12.With this, touch sensing module 14 can determine the lighting mode of light emitting module 12.
For instance, when light emitting module 12 is not luminous, touched by an object if touching sensor conductor 142 is sensed corresponding leaded light block 104, then touch sensing module 14 can start light emitting module 12 and emit beam.On the contrary, if light emitting module 12 has been in luminance, and senses by an object when touching sensor conductor 142 and to touch, then touch sensing module 14 can be closed light emitting module 12 and be stopped to emit beam, and perhaps changes the color of light emitting module 12 emitted lights.In fact, described touching sensor conductor 142 can be considered a capacitive sensing test point, when user's finger touches corresponding leaded light block 104, can to touching sensor conductor 142, excite a charge inducing value via the leaded light block 104 of correspondence, therefore can cause the change of electric capacity.Then, touching sensing element 144 can be by detecting the equivalent capacitance value amplitude of variation size of corresponding leaded light block 104, and then judge whether corresponding leaded light block 104 is touched.It is noted that all the touch-control startup is luminous but all can make touching sensor conductor 142 excite charge inducing value person, and is not limited to the part of human body.
In practice, the touching sensor conductor 142 of touch sensing module 14 has a sensing range 142a (shown in Fig. 2 A), and sensing range 142a is the zone of effectively sensing user touching.At this, the size of sensing range 142a should be proportional to the size of touching sensor conductor 142, in general, the size of sensing range 142a is generally the size that is equal to or is slightly larger than touching sensor conductor 142, and the scope that can touch when probably not being to use the person with finger presses.For instance, the size of described sensing range 142a probably is the scope of diameter 10mm.In addition, substrate 16 described in the utility model is a kind of printed circuit board (PCB) (PCB), and substrate 16 can be provided with the circuit element that possesses other function.For instance, when contactor control device 1 during as a control switch, substrate 16 more can be arranged in pairs or groups the pairing functional circuit of described control switch is set.On practice, described circuit board can be the soft printed circuit board (PCB) of flexible or the hard printed circuit board of flexible not, has in affiliated technical field and knows that usually the knowledgeable can freely replace.
What deserves to be mentioned is, light emitting module 12 of the present utility model is arranged on light guide 10 1 sides (just each light emitting module 12 is positioned at by the incidence surface 104a of each leaded light block 104), but not be arranged at the below of light guide 10, make integral thickness significantly to reduce.When traditionally light emitting module being arranged on the below of light guide, the integration thickness of light guide and light emitting module is about 2.8mm, and the utility model makes light guide 10 (about 0.6mm) add that the thickness of chart board 20 (about 0.2mm) significantly is reduced to 0.8mm because light emitting module 12 is arranged on light guide 10 1 sides.At this, the thickness of touch sensing module 14 is owing to having only 0.0356mm to 0.0712mm, so can ignore or be incorporated in the thickness of substrate 2.
Have in affiliated technical field and to know that usually the knowledgeable should understand, when using the capacitance type sensing technology, under the situation that integral thickness significantly reduces, can detect the sensing range 142a of identical size with littler touch sensing module 14, make the sensing sensitivity of touch sensing module 14 effectively to promote.With concrete instance, generally when judging that light guide 10 is whether touched, reaching 13pF with the equivalent capacitance value variable quantity of 14 sensings of touch sensing module usually is standard.If the equivalent capacitance value variable quantity of 14 sensings of touch sensing module does not reach 13pF, then judge not touched; Otherwise,, then judge touched if the equivalent capacitance value variable quantity of 14 sensings of touch sensing module surpasses 13pF.Touching sensor conductor in traditional touch-control sensing module generally needs the above size of diameter 10mm, can arrive above-mentioned equivalent capacitance value variable quantity by actual induction.Yet if when using the content that the utility model proposes and reducing the thickness of light guide 10, the diameter of the touching sensor conductor 142 in the touch-control sensing module 14 only needs 8mm can sense identical equivalent capacitance value variable quantity.That is to say that the utility model can reduce the touching sensor conductor 142 of configuration 36% area, and then save the cost of product.
With practical application, when contactor control device 1 of the present utility model is applied on the remote controller, when the user touches on the chart board 20 the corresponding symbol pattern, except the light that can switch touched symbol pattern present, more can control an appointed function.For example, when contactor control device 1 of the present utility model was applied to the cold air remote controller, different symbol patterns can corresponding opening/closing cool air, ON/OFF dehumidifying, lifting temperature or show the function of present temperature.Touch the symbol pattern of opening/closing cool air as the user after, the convertible color of described symbol pattern is opened or is closed with indication cold air, allows the present user mode of the easier identification remote controller of user by this.In other words, contactor control device 1 of the present utility model can arrange in pairs or groups traditional remote controller or control panel, and each function button display mode on improved remote control or the control panel allow each function on easier differentiation remote controller of user or the control panel.
(second embodiment)
Can not be sent in the adjacent leaded light block 104 in order to ensure light, the light-emitting area 104a of any two adjacent light guide zone pieces 104 is preferably can be not toward each other, air dielectric between promptly can be not only between two light-emitting area 104a in external series gap 102 more can have other to be suitable for the structure of shield lights.See also Fig. 4, it is the exploded view of the contactor control device of the utility model second embodiment.The places different with first embodiment are that the side 10a of the light guide 10 of the contactor control device 1a of second embodiment more is provided with shading member 18.
On practice, shading member 18 can be a kind of shading rubber belt in order to be covered in light guide 10 side 10a on every side, make light only can shed by the exiting surface 104b of each leaded light block 104, and can arrange in pairs or groups light emitting module 12 of shading member 18 forms a plurality of breach, makes light emitting module 12 ray cast can be entered in the leaded light block 104 of light guide 10.At this, the utility model does not limit the compound mode of shading member 18 and light guide 10, shading member 18 can stick in around the light guide 10, perhaps shading member 18 can be coated around the light guide 10, as long as there is shading member 18 to be arranged in external series gap 102, and in order to separate the light of each leaded light block 104, affiliated technical field person can its material of free conversion or compound mode.
(the 3rd embodiment)
See also Fig. 5, it is the exploded view of the contactor control device of the utility model the 3rd embodiment.The places different with second embodiment are that among the contactor control device 1b of the 3rd embodiment, shading member 18 does not directly contact light guide 10 and is arranged in the external series gap 102, only can be from the exiting surface 104b light that sheds to limit each leaded light block 104.On practice, the shading member 18 of the 3rd embodiment contactor control device 1b can be a kind of light-proof material and be placed on substrate 16 on, shading member 18 runs through the light of each leaded light block 104 in order to shaded portions.That is to say that shading member 18 is limited in the appointed area (for example in single leaded light block 104) in order to the transmission with light, and light only can be shed by exiting surface 104b in described appointed area.Certainly, the utility model more can utilize the housing of packing contactor control device 1b to serve as the shading member 18 of part, to save the cost of manufacture of shading member 18.
(the 4th embodiment)
See also Fig. 6, it is the part vertical view of the contactor control device of the utility model the 4th embodiment.The difference of the contactor control device 1c of the 4th embodiment and the contactor control device 1 of first embodiment is that each leaded light block 104 ' of contactor control device 1c is not connected to each other, and makes light guide 10 ' have a plurality of leaded light blocks 104 ' that disperse each other.At this, other relative positions of the 4th embodiment is identical with first embodiment with function, therefore repeats no more in present embodiment.
In addition, it is described to be similar to first embodiment, leaded light block 104 ', light emitting module 12 and touch sensing module 14 (with reference to figure 2A) can constitute single luminous touch control unit 3, because the leaded light block 104 ' of light guide 10 ' is independently of one another, therefore each luminous touch control unit 3 can become independently individuality, leaded light block 104 ' can be positioned on the substrate 16 in conjunction with location, touch sensing module 14 back in advance on the manufacture process.
(the 5th embodiment)
In addition, as shown in Figure 7, more can have specific shape in order to the groove 106 of ccontaining light emitting module 12.For instance, leaded light block 104 " but the edge indent forms groove 106, makes light emitting module 12 correspondence to be arranged in the groove 106.The contactor control device 1d of the 5th embodiment and the difference of the 4th embodiment are, each leaded light block 104 " shape more arrange in pairs or groups light emitting module 12 and have corresponding groove 106.For most of light that light emitting module 12 is produced can both enter leaded light block 104 smoothly ", incidence surface 104a can design groove 106 in advance to center on or coating light emitting module 12.That is to say that groove 106 is not limited in ccontaining light emitting module 12, more can assist incidence surface 104a to receive light.
At this, the utility model does not limit the true form of groove 106, as long as help incidence surface 104a to receive light, that groove 106 can be is square, semicircle, triangle or other suitable shape.
In sum, the contactor control device that the utility model embodiment is provided makes integral thickness significantly to reduce owing to the side that light emitting module is arranged on light guide, when using the capacitance type sensing technology, can effectively promote the sensing sensitivity of touch sensing module.In addition, the utility model is by the suitable external series gap of configuration of collocation, can limit the direction of dispersing of light in each leaded light block, and the light that makes each leaded light block be produced can not interfere with each other.When the user operates, the light that given out of each leaded light block of identification more easily, and then the controller of operational applications remote controller of the present utility model or other kind smoothly.
The above only is a preferable possible embodiments of the present utility model, is not so limits to claim of the present utility model, so the equivalence techniques that all utilization the utility model specifications and accompanying drawing content are done changes, all is contained in the scope of the present utility model.
