[Prior Art 3 [0002] As one of the important input devices, the keyboard has become an indispensable part of the electronic device. Conventional touch keyboards generally employ a structure in which a touch screen is stacked on a carrier substrate, and thus have a large thickness. And the familiar touch key ^ single out of the disk, it is difficult to meet the individual needs of consumers. 〇 [Summary of the Invention] [〇〇〇3] In view of the above problems, it is necessary to provide a thin touch-sensitive transparent keyboard 0, [0004] a touch-sensitive transparent keyboard, which includes one of the bottom-up settings a transparent substrate, a transparent button marking layer, a first insulating layer, a shielding layer, a second insulating layer, a position detecting layer and a transparent protective layer. A control module is disposed on the transparent substrate, and the control module is electrically connected to the button marking layer 、, the shielding layer and the position detecting layer. [0005] A touch-sensitive transparent keyboard includes a transparent substrate, and a transparent key marking layer is embedded in the transparent substrate. a shielding layer, an insulating layer, a position detecting layer and a transparent protective layer are disposed on the surface of the transparent substrate.

[(8) Compared with the prior art, the touch-sensitive transparent keyboard of the present invention directly sets a button marking layer on a transparent substrate of the touch screen, and does not require an additional carrier base 099120433 Form No. A0101 Page 3 / Total 14 Page 0992036114-0 The 201201049 board reduces the thickness of the touch keyboard. [Embodiment] [0007] The touch-sensitive transparent keyboard of the present invention is a transparent touch screen with a built-in button identification layer. The following two implementations are all based on a capacitive touch screen. Referring to the first embodiment of the present invention, the touch-sensitive transparent keyboard 100 includes a transparent substrate u, a transparent button marking layer 12, a first insulating layer 13, and a shielding layer U. A second insulating layer 15, a position detecting layer 16, and a transparent protective layer are collapsed. The transparent substrate 11 and the transparent protective layer 7 are made of a transparent insulating material such as glass or transparent resin. The transparent substrate Π includes an extension 丨丨丨, and a control module 18 is disposed on the extension 111. The control module 18 includes a ground terminal (not shown). The control module i8 is electrically connected to the button marking layer 12, the shielding layer 14 and the position detecting layer 16 via a transparent conductive line (not shown). The transparent conductive line may be made of other transparent conductive materials such as indium tin oxide (IT〇), zinc oxide doped aluminum (ΖΑΟ) or cadmium oxide (Cd〇). Referring to FIG. 2, the button marking layer 12 includes a transparent film 121 on which a plurality of button marks 123 and a driving circuit 125 printed around the button t 123 are printed or sprayed. The driving circuit 125 is made of a transparent conductive material and is electrically connected to the button mark 123 and the control module 18. In this embodiment, the transparent film 121 can be made of a transparent material such as a polyester film or a nylon film (PA). The button mark 123 is made of a transparent electroluminescent material, which can be illuminated when energized to show Its identification information. The button identifier 123 can be designed according to actual needs, such as an English child, a Chinese character or a 曰 character. The character identifier sfL of the button identifier 123 can be pre-stored in the control module 18, and the transparent protection 099120433 form number A0101 page 4 / 14 pages 0992036114-0 201201049 layer 1 7 is touched - -correspond. The driving circuit 125 is configured to control whether the button identifier 123 is illuminated or not. When the driving circuit 125 is powered by the control module 18, the button identifier 123 is illuminated and displayed; when the driving circuit 125 is not powered. The button identifier 123 does not emit light and is transparent. Referring to FIG. 1, the first insulating layer 13 and the second insulating layer 15 are made of a transparent insulating material such as a polyethylene terephthalate (PET). The first insulating layer 13 is used to space the _ button marking layer 12 and the shielding layer 14. The second insulating layer 15 is used to space the shield layer 14 and the position detecting layer 16. The shielding layer 14 is made of indium tin oxide (ΙΤ0), zinc oxide doped aluminum (ZA0) or cadmium oxide (CdO), etc., which is made of a transparent conductive material, and the shielding layer 14 is electrically connected to the ground of the control module 18. end. The shielding layer 14 is used to shield signal interference between the button marking layer 12 and the position detecting layer 16. The position detecting layer 16 is a working layer for detecting a touch position. In the embodiment, the position detecting layer 16 is a capacitive sensing layer composed of indium tin oxide (IT0), zinc oxide doped aluminum (ZA0 ^ ) or cadmium oxide. (CdO) and other transparent conductive materials. [0010] As shown in FIG. 3, the control module 18 can be synthesized into a transparent wafer or circuit using indium gallium oxide to make the touch transparent keyboard 100 completely transparent. [0011] The touch transparent The keyboard 100 can be a wired keyboard or a wireless keyboard. When the touch-sensitive transparent keyboard 100 is a wired keyboard, it is only necessary to provide a connection line to electrically connect the control module 18 to an external display device. When the touch-sensitive transparent keyboard 100 is a wireless keyboard, only a wireless transmission module is added to the control module 18, and a wireless 099120433 form number A0101 is displayed on the external display device. Page 5 of 14 pages 0992036114 -0 201201049 The wireless receiver corresponding to the transmission module can be used. [0012] The touch-sensitive transparent keyboard 100 of the first embodiment of the present invention directly sets the button marking layer 12 on the transparent substrate 11 of the touch screen, and does not require an additional carrier substrate, thereby greatly reducing the thickness of the touch keyboard, and the button identifier The layer 12 emits light under the control of the control module 18, and is convenient for the user to use under conditions of dark light or weak external light source. When the touch-sensitive transparent keyboard 100 is not powered, the whole is transparent, and the appearance is novel and beautiful. [0013] Referring to FIG. 4, the touch-sensitive transparent keyboard 200 of the second embodiment of the present invention has substantially the same structure as the touch-sensitive transparent keyboard 100 of the first embodiment, and the difference is that the button identification layer 22 is embedded in the transparent A through hole 213 is defined in the transparent substrate 21 in the substrate 21. The button marking layer 22 is electrically connected to the control module 18 through the through hole 21 3 . A shielding layer 14, a second insulating layer 15', a position detecting layer 16, and a transparent protective layer 17 are disposed on the surface of the transparent substrate 21 in this order from bottom to top. The in-line insertion of the button marking layer 22 can be realized by opening a receiving groove (not shown) in the transparent substrate 21. The touch-sensitive transparent keyboard 200 of the second embodiment of the present invention embeds the key marking layer 22 in the transparent substrate 21 of the touch screen, and does not require an additional carrier substrate, thereby greatly reducing the thickness of the touch keyboard. And the button marking layer 22 emits light under the control of the control module 18, which is convenient for the user to use under the condition that the light is dark or the external light source is weak. When the touch-sensitive transparent keyboard 200 is not energized, the whole is transparent, and the appearance is novel and beautiful. [0015] It can be understood that the position detecting layer 16 can also be a position detecting layer of a resistive touch screen, a surface acoustic wave type touch screen and an optical touch screen. [0016] It can be understood that the control module 18 can also be an opaque circuit module, 099120433 Form No. A0101 Page 6 / Total 14 Page 0992036114-0 201201049 The control module 18 is provided in the touch-sensitive transparent keyboard 100. One end is provided with an opaque protective cover.
