Embodiment
Fig. 1 is the keyboard of one embodiment of the invention, and Fig. 2 is the partial sectional view of the keyboard of Fig. 1.Please refer to Fig. 1 and Fig. 2, the keyboard 100 of present embodiment comprises a circuit film 110, a light-emitting film 120 and a plurality of keycaps 130.Circuit film 110 has a plurality of button contacts 112.Because Fig. 2 is the partial sectional view of the keyboard of Fig. 1, so Fig. 2 is an example with a button contact 112 only.Light-emitting film 120 is superimposed with circuit film 110.These keycaps 130 are disposed on light-emitting film 120 and the circuit film 110.In more detail, these keycaps 130 are positioned at button contact 112 tops.The keyboard 100 of present embodiment is to adopt light-emitting film 120 to throw light on, not only the thickness of light-emitting film 120 itself as thin as a wafer, and light-emitting film 120 directly provides area source and does not need extra light-guide device.Therefore, the keyboard 100 of present embodiment not only has voluntarily the function of illumination and makes things convenient for the user to operate in the not enough environment of illumination, and the keyboard 100 of present embodiment can also keep less thickness, meets the user and pursues the frivolous trend of product.
In addition, the keyboard 100 of present embodiment can be used as the external connection type keyboard of main frames such as for example general desktop computer or other electronic installation.At this moment, keyboard 100 also can comprise a shell 140, and keycap 130, light-emitting film 120 all are disposed in the shell 140 with circuit film 110, and shell 140 exposes keycap 130.Certainly, keyboard 100 also can in be built on notebook computer, mobile phone or other electronic installation, in order to the main frame of input instruction to these electronic installations.
In the present embodiment, light-emitting film 120 comprises one first electrode layer 122, a second electrode lay 124 and an electroluminescence material layer 126.Electroluminescence material layer 126 is disposed between first electrode layer 122 and the second electrode lay 124, is offered the electric current of electroluminescence material layer 126 and produces light with the second electrode lay 124 to utilize first electrode layer 122.The light-emitting film 120 of present embodiment is being example between keycap 130 and circuit film 110, but also can change circuit film 110 between keycap 130 and light-emitting film 120.In addition, first electrode layer 122 can be a transparent conductive material with the material of the second electrode lay 124, as indium tin oxide or other transparent conductive material.Yet first electrode layer 122 and the second electrode lay 124 wherein one deck also can adopt nontransparent electric conducting material, as long as this electrode layer does not have the demand of printing opacity.In addition, light-emitting film 120 also can be other light-emitting film except the electroluminescence film.
Utilize the selection of luminescent material, light-emitting film 120 also can send the light of different wave length according to the difference of the voltage that is applied in, and for example is blue light and green glow.Thus, not only be available for users to select the light of different wave length, also can utilize the change of wavelength and show the generation of power state for example or other incident according to its inclination.The voltage that is applied to light-emitting film 120 can be from the battery (not shown) that is disposed in the keyboard 100.Perhaps, the voltage that is applied to light-emitting film 120 also can be from the main frame that is connected via the connecting line (not shown) with keyboard 100.The user can utilize the wavelength of the light that the switch key control light-emitting film 120 that is arranged on the keyboard 100 sent.The user also can utilize keyboard to export dependent instruction to continuous main frame, again by the wavelength of the corresponding voltage of main frame output with the light that changes light-emitting film 120 and sent.Certainly, main frame also can change the wavelength of the light that light-emitting film 120 sent according to predefined program, to show the generation of power state for example or other incident.
In the present embodiment, each keycap 130 comprises a vaulted film 132 and a key sheet 134.Vaulted film 132 is disposed on light-emitting film 120 and the circuit film 110.Because vaulted film 132 has deformable characteristic, the touch-control sense in the time of therefore can providing the user to push, and need not use baroque X type support.And all vaulted films 132 also can all be produced on on a slice film, and are not only waterproof and avoid sheltering evil people and countenance evil practices, and more increase the convenience of assembling.The material of vaulted film 132 for example is silica gel or other suitable material.Key sheet 134 is disposed on the vaulted film 132, and has a printing opacity pattern P 10.Part key sheet 134 its printing opacity pattern P 10 of drawing only among Fig. 1.Printing opacity pattern P 10 has for example comprised English alphabet, numeral or other icon (icon).Certainly, be used for need not having the printing opacity pattern as 134 of the key sheets of the keycap 130 of space bar.In addition, each vaulted film 132 also can design a salient point 132b towards a surperficial 132a of light-emitting film 120 and circuit film 110, and the button contact 112 of success circuits for triggering film 110 is to send the success rate of signal when pushing keycap 130 to increase the user.In addition, keyboard 100 also can comprise a supporting bracket 150, and light-emitting film 120 and circuit film 110 are disposed between keycap 130 and the supporting bracket 150.
Moreover keyboard 100 also can comprise a photo-sensitive cell 160, and it electrically connects light-emitting film 120, and determines to open or close light-emitting film 120 according to a sensitization result.Thus, can design and make light-emitting film 120 luminous when ambient lighting is not enough automatically, and when ambient lighting is sufficient, close, with energy savings.In addition, keyboard 100 yet can comprise a switch 170, and it electrically connects light-emitting film 120, selects to open or close light-emitting film 120 voluntarily for the user.
Fig. 3 is the schematic diagram of the electronic installation of one embodiment of the invention.Please refer to Fig. 3, the electronic installation 200 of present embodiment comprises a main frame 220, a display module 230 and a keyboard 240.Display module 230 connects main frames 220 and by main frame 220 controls, and present embodiment is that to articulate main frames 220 with display module 230 be example.Keyboard 240 is similar to the keyboard 100 of Fig. 1, but does not have independent shell.Electronic installation 200 equally optionally sets photo-sensitive cell 242 and switch 244, and all the other resemblances are not then given unnecessary details.Keyboard 240 connects main frame 220, and photo-sensitive cell 242 can be connected the light-emitting film (not shown) by main frame 220 with switch 244.The electronic installation 200 of Fig. 3 is to be example with a notebook computer, and in other embodiments, electronic installation 200 can also be handheld apparatus such as stand hand-set, clamshell phone or PDA(Personal Digital Assistant).
In sum, in keyboard of the present invention and electronic installation, adopt thickness light-emitting film as thin as a wafer to come even illuminated keyboard, have the less advantage of integral thickness.In addition, utilize the selection of the luminescent material of light-emitting film, also can send different wave length on demand and increase availability.In addition, during fully with the synthetic keyboard of various complete film stack, also can eliminate the button slit and have water-proof function and avoid sheltering evil people and countenance evil practices.Moreover, also can arrange in pairs or groups photo-sensitive cell and switch and have the automatic illumination or the manual function of illumination, with energy savings.
Though the present invention discloses as above with preferred embodiment; right its is not in order to limit the present invention; have in the technical field under any and know the knowledgeable usually; without departing from the spirit and scope of the present invention; when can doing a little change and retouching, so protection scope of the present invention is as the criterion when looking claims person of defining.
