Embodiment
Fig. 1 has shown the operating system 1 of motor vehicle with vertical view, wherein, yet this operating system 1 have touch-screen 2 and be associated with this screen 2 at this unshowned computing unit.With vertical view, this screen 2 is shown in Fig. 1, thereby the user interface 3 of the diagram form that is provided by this screen can be provided.Except the middle section that information is shown therein, this user interface 3 also has a plurality of virtual keys 4, described button in this embodiment with up and down stackedly respectively the mode in row be arranged in left hand edge and the right edge of screen 2.In addition, in this embodiment, user interface 3 for example demonstrates status bar 5 and is used for adjusting volume 8 in the centre in the zone of bottom zone 6.Certainly, the present invention is not restricted to user interface shown in Figure 13.On the contrary, the present invention can be applicable on all user interfaces that can illustrate of screen, and irrelevant with the quantity of button 4 and shape thereof and arrangement.
Fig. 2 has shown screen 2 with the longitudinal sectional drawing of the line A-A in Fig. 1.As can finding out, screen 2 has visual sensing disc 7, and it extends on display device 8, by means of this display device 8, user interface 3 is shown.This visual sensing disc 7 is interpreted as sensor element transparent, dish type, and it extends on display device with the finger that obtains user for example with respect to the position by the shown user interface of this display.In this embodiment, this visual sensing disc 7 has two overlapping films 9 and 10, in this unshowned resistance matrix between this film 9 and 10, the place is applied with voltage in this resistance matrix, this voltage descends towards another edge from an edge and produce " short circuit ", transfer overvoltage value thus when two films 9,10 contact.This measurement by magnitude of voltage or obtain and to determine to activate point or contact point.That is, if the user is pressed against film 9 on film 10, can determine contact point by obtaining this voltage.Thus, this screen is resistive touch formula screen.According to this embodiment, visual sensing disc 7 is configured in display device 8 in integrated mode, thereby this display device 8 self does not have other (protection) disc, and perhaps visual sensing disc 7 forms the disc of display device 8.Yet according to alternative also can imagining at this unshowned embodiment, except (protection) disc of display device 8 additionally arranges visual sensing disc 7 and subsequently visual sensing disc 7 is installed to thus on display device with the correspondingly structure of (protection) dish.
According to an alternative embodiment, this touch-screen 2 is enacted in the screen of condenser type work, and therein, film 9,10 the surface that faces with each other are provided with metal oxide layer, wherein applies at the place, a bight of this coating the voltage that produces electric field.Capacitive character and ohmic touch-screen are general known, therefore can not elaborate it at this.
In the surface 11 freely that deviates from the film 9 of display device 8 or visual sensing disc 7 by contact, the position of finger on visual sensing disc 7 that can be by the user that will obtain and the virtual key 4 of user interface 3 one is associated operating operation system 1.Due to particularly in motor vehicle touch-screen 2 be positioned to away from the driver, so accuracy reduces.Difficulty is for the driver, in the situation that this sight only longways deviating road touch reliably the button 4 of expectation or the function of activate expecting.
Therefore, screen 2 advantageously has a plurality of setting elements 12, and it can be known by user's sense of touch ground.Aptly, each button 4 of user interface 3 is assigned the setting element of a corresponding sense of touch at this.
This setting element 12 is fabricated in the zone of the button 4 that illustrates under it by the Laser Processing to the surface 11 of visual sensing disc 7.Particularly by using the laser grinding method that setting element 12 is configured to recess 13 in surface 11, it has the degree of depth of 0.05mm to 0.1mm.Advantageously, by the seamed edge 14 restriction setting elements 12 of so-called gradual change or the zone that correspondingly is recessed into.Fig. 2 is schematically illustrated as recess 13 with this setting element 12, and Fig. 3 exemplarily shows one in the seamed edge 14 of gradual change with the detailed view that amplifies.The seamed edge 14 of this gradual change does not have acute angle, and particularly is provided with rounding section.By the minimum degree of depth of setting element 12 and the seamed edge 14 of this gradual change, do not hinder the visuality of passing on the user interface that is provided by display device of visual sensing disc 7 after being positioned at it.Thus, screen 2 is as broad as long in appearance for the user, yet but this setting element 12 is known on user's sense of touch ground.
Alternatively or additionally can stipulate, make surface 11 roughening in the zone of setting element 12 by Laser Processing, thereby the user knows higher friction valve and can position thus in the zone of setting element 12 or button 4, realizes correct operation to operating system 1 in simple mode equally thus.
The advantage that the screen 2 of making thus or operating system 1 have is, in the situation that do not affect outward appearance, the user can be known by means of setting element 12 senses of touch ground by simple mode the layout of button wherein, needn't change the basic structure of screen 2 or visual sensing disc 7 for this reason.Another advantage is, enough the required thickness/degree of depth of the several interval parts between film 9,10 is processed visual sensing disc 7, yet this external activation point place guarantees the high susceptibility of visual sensing disc 7 by the thickness/degree of depth (Sticke) that reduces.
Fig. 4 has shown an alternative embodiment, therein, replace the surface 11 of the Laser Processing of film 9 to produce in the following manner the recess 13 that is used to form setting element 12, that is, film 19 is keeping film 9 and 10 basically to keep each other being out of shape on the direction of film 10 in zone between the interval parts 15 of spacing.Make in the zone of film 9 between interval parts 15 on the direction of film 10 by deep-draw, thus the recess that is activating the point same generation in place and can be known by user's sense of touch ground.According to this embodiment, interval parts 15 is arranged and is orientated corresponding to the arrangement of the virtual key 4 on user interface 3, makes recess 13 be arranged in the zone of corresponding button 4.The formation of the interval parts 15 further auxiliary tanks by being provided with differing heights or the setting of recess.Therefore, for example between the interval parts 15 of two vicinities, less interval parts 16 can be set, it keeps film 9 and film 10 to keep spacing in the zone of recess 13.This is particularly favourable in the visual sensing disc 7 of condenser type work.
The arbitrary shape that can realize setting element 12 by this favourable structural scheme or the processing scheme of visual sensing disc 7.Therefore, can imitate simple button and slide block or roller by the corresponding moulding of each recess 13 or each setting element 12.Therefore, for example can realize the setting element of band shape in the zone of volume adjusting, the user can streak to adjust volume with finger thereon.Preferably, the profile of each Laser Processing on surface 11 is corresponding to the profile at its lower button 4 that shows of user interface 3.Certainly also can imagine, but the setting element that the net grid that surface 11 is known by Laser Processing with being provided with sense of touch are known to form a plurality of correspondingly senses of touch by Laser Processing.This particularly provides, and shown user interface 3 is configured to dynamic user interface, and for example the layout of button 4 changes at work or additional button can gradually occur and existing assembly can die down therein.
