Detailed description of the invention
Fig. 1 is the top view according to a kind of portable electronic devices of one embodiment of the invention. Please refer toFig. 1, the portable electronic devices 10 of the present embodiment comprises a display module 100 and a Keysheet module 200.Keysheet module 200 is electrically connected to display module 100.
Fig. 2 is the partial enlarged drawing of the Keysheet module 200 of Fig. 1, and Fig. 3 be Fig. 2 along I-I lineProfile. Please refer to Fig. 2 and Fig. 3, the Keysheet module 200 of the present embodiment comprise a circuit board 210,One optical waveguide layer 220, a decorative layer 230 and at least one button piece 240. Circuit board 210 has at least oneTouch-pressure switch 212. Optical waveguide layer 220 is arranged on circuit board 210, with directing light, wherein presses outClose 212 and be positioned at optical waveguide layer 220 times. Decorative layer 230 is to be arranged on optical waveguide layer 220 also in gummed modeThere is at least one opening 232, and the position of opening 232 is corresponding to the position of touch-pressure switch 212. ButtonSheet 240 is arranged on optical waveguide layer 220 and is arranged in opening 232, and button piece 240 has a light-transparent pattern244a makes can penetrate from the light-transparent pattern 244a of each button piece 240 from the light of optical waveguide layer 220.
In the present embodiment, Keysheet module 200 also can comprise a light source 250, and it is disposed in optical waveguide layer 220Lateral margin, to supply light to optical waveguide layer 220. Light source 250 can be light emitting diode etc. At another notIn the embodiment illustrating, also can supply light to optical waveguide layer by the other light sources of portable electronic devices220。
In the present embodiment, touch-pressure switch 212 by be formed on an electrode 212a on circuit board 210 andOne metal round cover (metaldome) 212b forms. The top of metal round cover 212b can be close to or supportTouch in the lower surface of optical waveguide layer 220, therefore in the time of user's application of force pressing keys sheet 240, optical waveguide layer 220Can transfer the application of force to metal round cover 212b press, make the metal round cover 212b can in electrical contact and this electricity of conductingUtmost point 212a. In addition, tactile feedback when metal round cover 212b can be used to provide user to press, with sideJust user knows whether and presses successfully.
In order to prevent the gap between light Self-decorating layer 230 and the button piece 240 of optical waveguide layer 220 to penetrate,The Keysheet module 200 of the present embodiment also can comprise a light shield layer 260, and it is disposed on optical waveguide layer 220,And between decorative layer 230 and the gap of button piece 240, to cover and to avoid optical waveguide layer 220 to be drawnThe light of leading is penetrated by this gap.
