Abstract
The utility model discloses an inductive element and a light guide plate structure. The inductive element and the light guide plate structure comprise an inductive element layer and a touch layer, wherein the touch layer is positioned above the inductive element layer, and may be a housing case, a panel, a button and the like; the light guide plate is arranged between the inductive element layer and the touch layer; and the two sides of the light guide plate are provided with light sources. The inductive element and the light guide plate structure obtained by the utility model can emit light penetrating through the touch layer on a surface, so that the inductive element and the light guide plate structure can be operated normally under a dim-light or light-free environment without using external light rays or affecting the using effect.
Description
Technical field
The utility model relates to a kind of touch sensible structure, especially a kind of sensing element and light conducting plate structure.
Background technology
Along with science and technology development and raising that information input is required, original mechanical key mode is difficult to satisfy people's needs more, touch-key has replaced the mechanical type button gradually, such as touch-key mode in smart portable device use more and more wider.But existing touch key-press mode (as capacitance type touch key) usually need be by the operation of extraneous light, and this gives the low light level or the operation do not had under the luminous environment is made troubles, and influences result of use.
Summary of the invention
The purpose of this utility model be provide for the deficiency that solves above-mentioned technology a kind of carry illumination effect, at the low light level or there be not the sensing element and a light conducting plate structure that also can normally use under the luminous environment.
In order to achieve the above object, sensing element that the utility model is designed and light conducting plate structure, it comprises sensing element layer and touch layer, touch layer is positioned at sensing element layer top, touch layer can be a casing, panel, button etc., be provided with light guide plate between described sensing element layer and the touch layer, the light guide plate both sides are provided with light source.Light guide plate can be conducted the light of light source, this light can the uniform penetration surface touch layer, the sensing element layer also can penetrate light guide plate and touch layer simultaneously, sense the operation of user on touch layer, thereby guarantee at the low light level or do not have result of use under the luminous environment, and light source is positioned at the side, thereby the false sense of avoiding electrical Interference to produce should.In order to connect better more closely, described touch layer and light guide plate, light guide plate and sensing element layer can be bonding mutually.In order to play support effect well, the feel when increasing operation can be provided with the printing opacity middle layer between described touch layer and the light guide plate or between light guide plate and the sensing element layer or aforementioned both is provided with the printing opacity middle layer.Described printing opacity middle layer is that the material that can not influence translucent effect and inductive effects forms, and can be TPU layer or layer of silica gel or PC layer or PMMA layer, also can be bonding mutually between each layer.For typing is made up in above-mentioned printing opacity middle layer better, play supporting role well again, described printing opacity intermediate layer perimeter can be provided with bracing frame.
Resulting sensing element of the utility model and light conducting plate structure self can luminously penetrate the touch layer on surface, thereby need not by extraneous light, the low light level or do not have under the luminous environment also can normal running, do not influence result of use.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment 1;
Fig. 2 is the structural representation of the utility model embodiment 2;
Fig. 3 is the printing opacity middle layer partial sectional view of the utility model embodiment 3.
Among the figure: sensing element layer 1, touch layer 2, bracing frame 3, light guide plate 4, light source 5, printing opacity middle layer 6.
Embodiment
The utility model will be further described in conjunction with the accompanying drawings below by embodiment.
As shown in Figure 1, described sensing element of present embodiment and light conducting plate structure, it comprises sensing element layer 1 and the touch layer 2 that is used for the capacitance touch induction, touch layer 2 is positioned at sensing element layer 1 top, is provided with light guide plate 4 between described sensing element layer 1 and the touch layer 2, and light guide plate 4 both sides are provided with light source 5, but light guide plate 4 conducting light, and light source 5 is positioned at the side, thereby avoids the false sense of sensing element layer 1 to answer, and is bonding mutually between each layer.
This sensing element and light conducting plate structure are applied on the mobile phone, can make the luminous induction draw runner of full induction zone easily.Compound more changeable colored light effect promptly can be operated multimedia function easily, can be used as the volume bar again and use.
As shown in Figure 2, described sensing element of present embodiment and light conducting plate structure, embodiment 2 the basis on, all be provided with printing opacity middle layer 6 between described touch layer 2 and the light guide plate 4 and between light guide plate 4 and the sensing element layer 1, described printing opacity middle layer 6 is a layer of silica gel.
This sensing element and light conducting plate structure are applied on the car audio system, touch layer 2 is provided with various handle icon, in the past because car audio system often need be in the darker occasion use of light, can only solve the luminous problem of symbol by perforate, perforate is too small can not satisfy the luminous uniform needs of large icons, the excessive induction amount loss of perforate can be very big, causes induction insensitive.And this structure can increase the area raising induction sensitivity of induction zone because no longer need perforate, can take into account the luminous uniform needs of large icons requirement simultaneously, and practicality is stronger.
Printing opacity middle layer 6 in the present embodiment also can be TPU layer or PC layer or PMMA layer.
Embodiment 3
As shown in Figure 3, described sensing element of present embodiment and light conducting plate structure on the basis of embodiment 3, are provided with bracing frame 3 made of iron around 6 layer of silica gel of printing opacity middle layer.
