Fig. 1 is the part schematic diagram of the touch control panel device of prior art; And
The part schematic diagram that Fig. 2 is the touch control panel device that proposed according to one preferred embodiment of the present invention.
Wherein, description of reference numerals is as follows:
Embodiment
Please refer to Fig. 2, its part schematic diagram that is the touch control panel device 100 that proposed according to one preferred embodiment of the present invention, as shown in Figure 2, touch control panel device 100 comprises that a transparency carrier 102, at least one decorative layer 104(show one deck in Fig. 2, but not limit by this), a plurality of printing opacity electric conduction routing 106 and a reflecting plate 108.Transparency carrier 102 can be the transmitting substrate (for example glass protection sheet) being applied on general contact panel, and transparency carrier 102 has in the one side of the corresponding frame region 110 of a frame region 110 and is formed with a printing opacity induction electrode layer 112.In general, printing opacity induction electrode layer 112 for example induces the position of touch of user on transparency carrier 102 in the mode of detecting capacitance variations, with the effect of performance touch-control location, its related electrode configuration and forming technique are common in prior art, therefore repeat no more in this.Below for the design of decorative layer 104, a plurality of printing opacity electric conduction routing 106 and reflecting plate 108, be described in detail respectively.
As shown in Figure 2, decorative layer 104 is formed in frame region 110, in this embodiment, decorative layer 104 is colored or white, such as can be with mode of printing, be formed at a colour (as redness etc.) ink layer or the white ink layer in frame region 110, but not limit by this, it also can be black ink layer, certainly in other color blocking layer with same effect is also encompassed in, the black that for example utilizes the long-pending mode in chemical Shen to be shaped, colour or white light resistance layer etc., whereby, decorative layer 104 just can be brought into play the outward appearance and auxiliary effect of covering the inside cabling of touch control panel device 100 of decorating touch control panel device 100 with intrinsic colour.
A plurality of printing opacity electric conduction routing 106 compartment of terrains are formed on decorative layer 104 and are electrically connected on printing opacity induction electrode layer 112, be used for transmitting the signal that printing opacity induction electrode layer 112 produces, in this embodiment, printing opacity electric conduction routing 106 can be by tin indium oxide (Indium Tin Oxide, ITO), nano carbon tubes (Carbon Nanotube, CNT), or how the printing opacity conductive material such as meter Yin Si forms, furthermore, printing opacity electric conduction routing 106 can be preferably identical with the composition material of printing opacity induction electrode layer 112, this design can be created in the process of the moulding of carrying out printing opacity induction electrode layer 112 can carry out the effect of the moulding of printing opacity electric conduction routing 106 simultaneously, whereby, not only can omit metal routing molding manufacture procedure, also can reduce further touch control panel device 100 required processing procedure time of expending in trace configurations simultaneously.
By above-mentioned configuration, even at decorative layer 104, for light transmission, preferably a white or colored ink layer or a white or colorama resistance layer allow the penetrable decorative layer 104(of extraneous light as shown in Figure 2 conventionally) to be incident in printing opacity electric conduction routing 106 in the situation that, adding reflecting plate 108 can all reflect back the light by decorative layer 104 and a plurality of printing opacity electric conduction routing 106, therefore, touch control panel device 100 can utilize the light transmission features of printing opacity electric conduction routing 106 to solve prior art because occurring the problem of obviously bright dark variation on the transparency carrier that cause was caused of metal routing reflection ray and can allowing the visual problem to metal routing of user, and also can solve the effect of the intraware that the impure problem of above-mentioned frame region color and performance cover touch control panel device 100 (as backlight module etc.) and light leakage, thereby promote appearance tactile impression and the visual adaptability when using operation of touch control panel device 100.
It is worth mentioning that, because a plurality of printing opacity electric conduction routing 106 can allow light penetration, therefore, touch control panel device 100 can not need additionally by the mode that increases the thickness of decorative layer 104, to cover a plurality of printing opacity electric conduction routing 106, therefore in the present invention, decorative layer 104 as be photoresist layer, a thickness T of decorative layer 104
1can select to be effectively reduced between 0.5 μ m to 2 μ m, and take the thickness T that 1 μ m to 1.5 μ m is decorative layer 104
1preferable range, when decorative layer 104 as while being ink layer, its thickness T
1can select to be effectively reduced between 3 μ m to 20 μ m, and take the thickness T that 5 μ m to 10 μ m are decorative layer 104
1preferable range, to avoid the situation of the above-mentioned printing opacity induction electrode fault rupture being caused because decorative layer is blocked up to occur, in addition, the cost that also accounts for contact panel due to decorative layer has suitable proportion, therefore effectively reduce decorative layer thickness, can further save material cost.
In addition, in order to avoid further touch control panel device 100 to occur that the too high situation of overall resistance occurs after using printing opacity electric conduction routing 106 substituted metal cablings, in the present invention, touch control panel device 100 optionally adopts the mode that is electrically connected to design that increases the size (as width or thickness etc.) of printing opacity conductive wire 106 or change printing opacity electric conduction routing 106 and printing opacity induction electrode layer 112, to bring into play the effect of its overall resistance of reduction.For instance, a width W of each printing opacity electric conduction routing 106 can be increased to the scope between 10 μ m to 5mm, or a thickness T of each printing opacity electric conduction routing
2can be increased to the scope between 100A to 100 μ m; Or a plurality of printing opacity electric conduction routing 106 can be designed in the mode of two terminated lines from printing opacity induction electrode layer 112 in parallel with printing opacity induction electrode layer 112, namely so-called bilateral cabling (Double Routing) design.
In sum, touch control panel device provided by the present invention adopts with printing opacity electric conduction routing substituted metal cabling and utilizes baffle reflection by the design of the light of decorative layer and printing opacity electric conduction routing, to solve prior art because occurring the problem of obviously bright dark variation on the transparency carrier that cause was caused of metal routing reflection ray and can allowing the visual problem to metal routing of user.Thus, the present invention not only can solve the impure problem of above-mentioned frame region color, also can there is the effect of covering intraware (as backlight module etc.) with the light leakage of touch control panel device with reflecting plate simultaneously, thereby promote appearance tactile impression and the visual adaptability when operation is used of touch control panel device.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
