Embodiment
Please with reference to Fig. 1, it has illustrated according to the present invention the synoptic diagram of the portable electronic devices of one preferred embodiment.Portable electronic devices 100 for example is that (Personal Digital Assistant PDA), comprises a device body 110, a keyboard 130 and a light source 150 (shown in the 5th figure) for a Smartphone (Smart phone) or a personal digital assistant.Keyboard 130 is arranged at device body 110, and light source 150 is arranged in the device body 110.
Please with reference to Fig. 2, it has illustrated the exploded view of the keyboard of one embodiment of the invention.Keyboard 130 comprises a printed circuit board (PCB) 131, several thin film switches 132, a touch-sensitive panel 135, a light-leading film 137 and a key groups 139.These a little thin film switches 132 are arranged on the included surperficial 131a of printed circuit board (PCB) 131.Touch-sensitive panel 135 for example is a capacitive touch control plate, is positioned at the top of these a little thin film switches 132, and comprises one first induction zone S1 and one second induction zone S2.In present embodiment, the sensitivity of the first induction zone S1 for example is different with the sensitivity of the second induction zone S2.
Light-leading film 137 is arranged on the touch-sensitive panel 135, and light source 150 is positioned at a side (as shown in Figure 5) of light-leading film 137.Key groups 139 is arranged on the light-leading film 137, and has several first button 139a and several second buttons 139b.These a little first button 139a for example are several letter keys that are arranged in the QWERTY form, and these a little second button 139b for example are several directionkeys and function key.Certainly, the first button 139a also can be arranged in AZERTY form, QWERTZ form or DVORAK form.
The position of these a little first button 139a and these a little second button 139b corresponds respectively to the position of these a little thin film switches 132.These a little first button 139a of part are positioned at the top of the first induction zone S1, and these a little second button 139b of part are positioned at the top of the second induction zone S2.In present embodiment, the arrangement of these a little first button 139a is than the dense arrangement of these a little second button 139b.That is to say that in key groups 139, the number of the first button 139a of per unit area is more than the number of the second button 139b of per unit area.
Setting by touch-sensitive panel 135; The user can be respectively slides finger with input control order on corresponding to the surface of the first button 139a of the first induction zone S1 and on the surface corresponding to the second button 139b of the second induction zone S2, and the user also can import various functions corresponding to button by the mode of pushing the first button 139a and the second button 139b.Therefore, the additional function of the keyboard 130 of present embodiment increases.Moreover because the sensitivity of the first induction zone S1 and the second induction zone S1 is different, therefore, the application mode of the keyboard 130 of present embodiment can richlyer change, and makes the user improve in operational elasticity.
Now the portable electronic devices 100 with present embodiment further specifies as follows.Please be simultaneously with reference to Fig. 2 and Fig. 3, Fig. 3 has illustrated the sectional view of key groups of the profile line 3-3 ' in Fig. 2 of one embodiment of the invention.Because the arrangement of the first button 139a of key groups 139 is than the dense arrangement of the second button 139b, therefore, each first button 139a comprises a teat 139p, to let the user can distinguish each first button 139a easily.Thus, the thickness T 1 of each first button 139a is greater than the thickness T 2 of each second button 139b.
Shown in one embodiment of the invention of Fig. 2, touch-sensitive panel 135 comprises several first sensing unit 135a and several second sensing units 135b.These a little first sensing unit 135a are positioned at the first induction zone S1, and these a little second sensing unit 135b are positioned at the second induction zone S2.Because the thickness T 1 of each first button 139a of present embodiment is greater than the thickness T 2 of each second button 139b; And the surface that the design of teat 139p makes the user touch these a little first button 139a is a discontinuous surface; Therefore, the area of the area of each first sensing unit 135a greater than each second sensing unit 135b adopted in the design of the first sensing unit 135a and the second sensing unit 135b.Certainly, having common knowledge the knowledgeable in this technical field should understand, and it is prerequisite that the area design of the first sensing unit 135a needs can sense user's moveable finger with the first sensing unit 135a.
In addition, please with reference to Fig. 4, it has illustrated the top view of the keyboard among Fig. 2 when group is established.In the present embodiment, the side of each first button 139a and the side of each first sensing unit 135a form an angle theta 1, and angle theta 1 for example is 45 degree.The side of each second button 139b and the side of each second sensing unit 135b form another angle theta 2, and angle theta 2 for example is 45 degree.So, can improve the induction uniformity coefficient of the integral body of the first induction zone S1 and the second induction zone S2 respectively, make the quality of induction to promote.
Certainly, as shown in Figure 2, key groups 139 can also comprise an acknowledgement key 139c, and acknowledgement key 139c is between these a little first button 139a.So, after the user carried out touch controllable function by touch-sensing plate 135, can directly push acknowledgement key 139c for example was the action of confirming.In addition, keyboard 130 can also comprise an elastic component 133, is arranged between printed circuit board (PCB) 131 and the touch-sensitive panel 135, in order to a cushion effect to be provided.
Please with reference to Fig. 5, it has illustrated the sectional view of keyboard of the profile line 5-5 ' in Fig. 4 of one embodiment of the invention.Portable electronic devices 100 also comprises light source 150, is arranged in the device body 110 (as shown in Figure 1), and is positioned at a side of light-leading film 137.In present embodiment, light-leading film 137 for example is a transparent material.So, when the luminance shortage of environment, light source 150 can provide light, operates the keyboard 130 of portable electronic devices 100 to make things convenient for the user.
Below utilize an example that the application mode of the portable electronic devices of present embodiment is described.Amplify the regional area of a picture when user's desire; And when this regional area is positioned at the corner of picture; User's finger that can slide on corresponding to the surface of the second button 139b of the second induction zone S2 makes that the vernier in the screen of portable electronic devices 100 moves to this regional area.At this moment, the user is moveable finger deasil or widdershins on corresponding to the surface of the first button 139a of the first induction zone S1 again, to amplify this regional area of picture.Acknowledgement key 139c can be when having menu to occur, in order to the option of confirming expediently to choose.Certainly, the application mode of the portable electronic devices of present embodiment is not as limit, and when the user utilized portable electronic devices 100 to take a picture, the first induction zone 135a of user's touch-sensitive panel 135 also capable of using adjusted Jiao and gathers.
Keyboard that the above embodiment of the present invention disclosed and the portable electronic devices of using it are provided with the function that the touch-sensing plate makes that keyboard possesses touch-control simultaneously and pushes.In addition, the touch-control sensing plate has two induction zones that sensitivity is different, makes the operational elasticity of portable electronic devices of present embodiment improve, and has improved convenience more simultaneously.
In sum, though the present invention discloses as above with a preferred embodiment, so it is not in order to limit the present invention.Have common knowledge the knowledgeable in the technical field under the present invention, do not breaking away from the spirit and scope of the present invention, when doing various changes and retouching.Therefore, protection scope of the present invention is as the criterion when looking accompanying the claim person of defining.
