Description

    BACKGROUND
  • [0001]
    Currently there are at least two different techniques that a user of a mobile telephone can utilize in order to input text messages. The first technique is to utilize the numeric input buttons of the mobile phone to input characters, which can be slow and tedious considering that some characters and techniques involve several key depressions per character. A second technique is for the mobile phone to be enabled with a capacitive sensor and character recognition abilities such that its user is able to gesture or “write” with his or her finger over its buttons (without depressing the buttons) in order to input alphanumeric characters. This provides a quicker way for entering text into a mobile phone. Additionally, gestures can also be used to navigate through the mobile phone operating system and/or menus. However, there are disadvantages to the conventional techniques for fabricating the capacitive sensors associated with the finger gesture input.
  • [0002]
    For example, a conventional technique is described in PCT publication WO 02/100074 (the U.S. relative is published as US 2003/0025679) in which the capacitive sensor of a mobile phone includes holes to allow keypad posts to pass through in order to activate switches associated with depressed keys. One of the disadvantages of this conventional technique is that it involves a lot of compensation in the sensing circuitry of the capacitive sensor to accommodate the irregular sensor design associated with routing around the holes. As such, this type of capacitive sensor can require increased development effort, time, and expense to adapt to different electronic devices, since the compensation usually has to be customized for each hole layout, and reconfigured when the key post holes are rearranged.
  • [0003]
    The present invention may address one or more of the above issues.

  • DESCRIPTION OF PREFERRED EMBODIMENTS
  • [0020]
    Reference will now be made in detail to embodiments of the invention, examples of which are illustrated in the accompanying drawings. While the invention will be described in conjunction with embodiments, it will be understood that they are not intended to limit the invention to these embodiments. On the contrary, the invention is intended to cover alternatives, modifications and equivalents, which may be included within the spirit and scope of the invention as defined by the appended claims. Furthermore, in the following detailed description of the present invention, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, it will be obvious to one of ordinary skill in the art that the present invention may be practiced without these specific details. In other instances, well known methods, procedures, components, and circuits have not been described in detail as not to unnecessarily obscure aspects of the present invention.
  • [0021]
    FIG. 1 is a diagram of an exemplary mobile telephone 100 that can be implemented to include one or more embodiments in accordance with the present invention. Specifically, a capacitive sensor (not shown) can be integrally disposed within a keypad region 106 of mobile phone 100 thereby enabling both conventional use of keys 108 of the keypad region 106 having tactile “clicking” feedback while also enabling the capture of pointing and gesturing input when a user slides his or her finger over the surface of the keypad region 106 with or without actually depressing the keys 108. For example, if a user moved his or her finger over keypad region 106 to form the letter “b”, the capacitive sensor would detect this motion and its character recognition circuitry would identify the motion and subsequently the letter “b” can be presented on a display 104 of mobile phone 100. In this manner, a user of mobile phone 100 can enter alphanumeric text (or commands or other inputs) more easily with his or her finger via the capacitive sensing device than by utilizing keys 108 of keypad 106.
  • [0022]
    It is noted that, keys 108 of mobile phone 100 can be lighted from behind. As such, the capacitive sensor can be implemented such that it is substantially transparent in regions beneath the keys 108 in order to allow the light to pass from behind the capacitive sensor to light the tops of keys 108. In this manner, the lighting of the keys 108 is not significantly adversely affected by the inclusion of the capacitive sensing device that is part of keypad 106.
  • [0023]
    FIG. 2 is a diagram of an exemplary keypad assembly 200 in accordance with an embodiment of the present invention. Specifically, keypad assembly 200 includes a capacitive sensor 208 that can be a thin and flexible sensor that utilizes substantially transparent components. Within one embodiment, capacitive sensor 208 can include a single sheet capacitive sensor that includes a single layer of substantially transparent conductive material, e.g., indium tin oxide (ITO), and an extra layer of substantially opaque conductive material (e.g., silver ink, carbon ink, a mixture of silver and carbon inks, etc.) that protects the substantially transparent conductive material against cracking during manufacture and/or repetitive use. Since the substantially opaque conductive material application is also a redundant electrical path, it can be selectively disposed where desired. For example, the substantially opaque conductive material could be masked around certain features in the sensing region of the capacitive sensor 208 to allow illumination to pass directly through capacitive sensor 208, thereby allowing keys 204 of keypad structure 206 to be illuminated to enable visibility of keys 204 in low light. The single sheet capacitive sensor 208 can also include a substantially transparent substrate, or the various patterns of the single sheet captive sensor 208 can be disposed on an existing component of the keypad assembly 200.
  • [0024]
    The keypad assembly 200 for an electronic device (e.g., 100) includes keypad structure 206, a keymat 210 that is deformable to actuate switch sensors 214 via key posts 212, and capacitive sensor 208 that is coupled to the keymat 210 and the keypad structure 206. In this manner, when a user finger 202 exerts a downward force on one of keys 204, that key 204 is depressed (as shown) which in turn causes the deformation of capacitive sensor 208 along with keymat 210 which results in the corresponding key post 212 actuating one or more switch sensors 214. It is noted that capacitive sensor 208 is not disposed beneath the keymat 210 such that keypad post holes do not have to be formed within capacitive sensor 208, since such holes would complicate the sensing circuit (not shown) utilized to interpret signals received from capacitive sensor 208.
  • [0025]
    In one embodiment, capacitive sensing device 208 can be bonded to the top of the keymat 210 and the keypad structure 206 can be bonded to capacitive sensing device 208. It is noted that keypad structure 206 could be many separate discrete keys that can be disposed on capacitive sensing device 208 or disposed on some intermediate member (or component) that is disposed on capacitive sensing device 208.
  • [0026]
    Within FIG. 2, capacitive sensor 208 can be integrated into the keymat 210 which in one embodiment can be implemented with some type of rubber material. The keys 204 of keypad structure 206 can be rigid plastic buttons which include both clear and opaque regions (e.g., painted on the outside with holes in the paint) to let any back lighting through for illumination. It is noted that the indicia of keys 204 can look darkened when there's no light behind them and they can also glow when the back lighting is activated such as in response to a user activating one of buttons 204 or a status change of the electronic device (e.g., 100). It is pointed out that capacitive sensor 208 can be flexible and thin enough such that it does not inhibit the tactile response associated with buttons 204. Instead, capacitive sensor 208 enables the desired tactile response of the keys 204 which may include a responsive click or snap or less resistant responses. It is noted that the keypad assembly 200 is one integral unit.
  • [0027]
    It is understood that capacitive sensor 208 includes a sensing region which can include where the buttons 204 are located on a electronic device or system (e.g., keypad region 106). However, the sensing region of capacitive sensor 208 may be any shape, may be smaller than keypad region 106, and/or may extend outside of where the buttons 204 are into areas that can be covered up by the housing of the electronic device (e.g., 100).
  • [0028]
    It is noted that a single sheet capacitive sensor can include a single substrate that has two or more conductive sensing patterns disposed thereon in a common layer that can be utilized for, but not limited to, 2-dimensional capacitive sensing.
  • [0029]
    FIG. 3A is a diagram of an intermediate step in constructing an exemplary capacitive sensor 300A that includes a first capacitive sensor pattern 302 and a second capacitive sensor pattern 304 in accordance with an embodiment of the present invention for a capacitive sensing device. For example, capacitive sensor pattern 302 includes electrically coupled horizontal capacitive sensor traces while capacitive sensor pattern 304 includes the as yet electrically uncoupled vertical sensor traces.
  • [0030]
    It is noted that capacitive sensor patterns 302 and 304 each includes a layer of substantially transparent conductive material (not shown) along with a layer of substantially opaque conductive material (shown). There are a wide variety of ways in accordance with the present embodiment to fabricate capacitive sensor patterns 302 and 304. For example, in one embodiment a sputtering process can be used to coat one side of a substantially transparent flexible substrate 301 with a layer of substantially transparent conductive material (e.g., ITO). The substantially transparent conductive material can then be selectively etched away from the surface of the substantially transparent flexible substrate 301, revealing an intended “diamond” patterns 302 and 304 which can be used for a capacitive sensing process. Alternatively, the substantially transparent material can be applied in any manner to create the intended diamond patterns 302 and 304. It is noted that patterns 302 and 304 may include any shapes and are not limited to the “diamond” patterns or the horizontal and vertical layout shown. After the etching process of the substantially transparent conductive material, a first layer of substantially opaque conductive material is deposited on top of the substantially transparent conductive material in the desired areas. Within capacitive sensor 300A, the substantially transparent conductive material and the substantially opaque conductive material are shown having a substantial one-to-one correspondence and alignment which is why the substantially transparent conductive material is not shown.
  • [0031]
    Furthermore, it is noted that in various embodiments of the present invention, the first and second conductive sensor patterns are comprised of the same type of substantially transparent conductive material. It is further noted that in various embodiments of the present invention, the first and second conductive sensor patterns are comprised of different types of substantially transparent conductive materials. Additionally, it is noted that in various embodiments of the present invention, the first and second conductive sensor patterns are comprised of the same type of substantially opaque conductive material. It is further noted that in various embodiments of the present invention, the first and second conductive sensor patterns are comprised of different types of substantially opaque conductive materials.
  • [0032]
    Within FIG. 3A, capacitive sensor pattern 302 includes diamond shapes 318, 320, 322, 324, 326 and 328 which can be disposed on a substantially transparent flexible substrate 301 as described herein. The diamonds shapes 318, 320 and 322 of sensor pattern 302 have been disposed such that they are each electrically coupled together while diamonds shapes 324, 326 and 328 have been disposed such that they are each electrically coupled together. As such, the components of capacitive sensor pattern 302 could be utilized if coupled to capacitive sensing circuitry (not shown).
  • [0033]
    Alternatively, capacitive sensor pattern 304 includes isolated diamond shapes 306, 308, 310, 312, 314 and 316 which can be disposed on the substantially transparent flexible substrate 301 as described herein. The diamond shapes 306, 308, 310, 312, 314 and 316 are electrically isolated and are therefore not yet useful as input to capacitive sensing circuitry. However, it is pointed out that the substantially transparent conductive material of the diamond shapes of capacitive sensor patterns 302 and 304 exist with a single layer which is advantageous for fabricating a capacitive sensing device that is thin and flexible.
  • [0034]
    Within FIG. 3A, it is noted that the substantially transparent flexible substrate 301 of the present embodiment may be implemented in a wide variety of ways. For example, the substantially transparent flexible substrate 301 can be implemented with, but is not limited to, Polyethylene Terephthalate (PET). Additionally, the substantially transparent flexible substrate 301 can have a diverse range of thickness which provide a desired amount of flexibility. For example, the substantially transparent flexible substrate 301 can have a thickness of, but is not limited to, roughly 0.07 millimeters (mm). It is noted that substrate 301 may be implemented such that one or more portions of it are not substantially transparent (e.g., opaque markings, and the like). Additionally, the layer of substantially transparent conductive material of both capacitive sensor patterns 302 and 304 can be implemented with diverse materials such as, but not limited to, indium tin oxide (ITO) or any other substantially transparent conductive material. Moreover, the layer of substantially opaque conductive material can be implemented in a wide variety of ways in accordance with the present embodiment. For example, the substantially opaque conductive material can be implemented as, but not limited to, conductive ink (e.g., silver ink, carbon ink, mixture of silver and carbon inks, and the like).
  • [0035]
    FIG. 3B is a diagram of an exemplary capacitive sensor 300B that includes conductive bridges in accordance with an embodiment of the present invention for a capacitive sensing device. Specifically, capacitive sensor 300B illustrates one embodiment of electrically coupling isolated diamonds 306, 308, 310, 312, 314 and 316 of capacitive sensor pattern 304 during a fabrication process of a capacitive sensing device.
  • [0036]
    After the operation associated with FIG. 3A have occurred as described herein, an insulator 350 can then be disposed in areas where conductive bridges (e.g., 352 and 354) of sensor pattern 304 will cross the sensor traces of sensor pattern 302 to facilitate electrically coupling of diamonds 306, 308, 310, 312, 314 and 316. For example, insulator 350 can be disposed between diamonds 310 and 308 of sensor pattern 304 and also between diamonds 308 and 306. Furthermore, insulator 350 can be disposed between diamonds 312 and 314 of sensor pattern 304 and also between diamonds 316 and 314.
  • [0037]
    Within FIG. 3B, a substantially opaque conductive material is next disposed to create conductive bridges (e.g., 352 and 354) that electrically couple diamonds 306, 308, and 310 together and diamonds 312, 314 and 316 together of sensor pattern 304 and does not electrically couple to sensor pattern 302. Specifically, the substantially opaque conductive material is disposed to create a conductive bridge 352 which electrically couples diamonds 306 with 308 of sensor pattern 304. Additionally, the substantially opaque conductive material is disposed to create a conductive bridge 354 which electrically couples diamonds 314 with 316. It is appreciated that diamonds 308 with 310 are also electrically coupled by a conductive bridge similar to bridge 354 while diamonds 314 with 312 are electrically coupled by a conductive bridge similar to bridge 352. In this manner, diamonds 306, 308 and 310 of sensor pattern 304 are electrically coupled while diamonds 312, 314 and 316 are electrically coupled.
  • [0038]
    In this manner, a single layer of substantially transparent conductive material can be utilized in order to fabricate a two-dimensional capacitive sensing device. It is noted that by including the layer of substantially opaque conductive material over the substantially transparent conductive material, the substantially transparent conductive material is protected from damage during manufacture and/or repetitive use of the capacitive sensing device. Additionally, the substantially opaque conductive material can also provide electrical redundancy for the substantially transparent conductive material if the substantially transparent conductive material fails. Therefore, a more reliable and thinner capacitive sensor device can be fabricated.
  • [0039]
    It is noted that a substantially transparent insulator can be disposed over capacitive sensor 300B in order to provide a layer of protection for capacitive sensor patterns 302 and 304 along with the conductive bridges (e.g., 352 and 354).
  • [0040]
    Within FIG. 3B, insulator 350 can be implemented in a wide variety of ways in accordance with the present embodiment. For example, insulator 350 can be implemented as, but is not limited to, a substantially transparent material, a substantially opaque material, an opaque material, and/or a printed dielectric material. Additionally, the substantially opaque conductive material utilized to create the conductive bridges (e.g., 352 and 354) can be implemented in diverse ways in accordance with the present embodiment. For example, the substantially opaque conductive material can be implemented as, but not limited to, conductive ink (e.g., silver ink, carbon ink, mixture of silver and carbon inks, and the like). It is noted that conductive bridges (e.g., 352 and 354) can be implemented in diverse ways in accordance with the present embodiment. For example, conductive bridges (e.g., 352 and 354) can be implemented as, but is not limited to, a substantially transparent conductive material, a substantially opaque conductive material, and/or an opaque conductive material.
  • [0041]
    It is understood that the substantially opaque conductive material, substantially transparent conductive material, conductive bridges, and/or insulators described herein can be disposed by utilizing, but not limited to, one or more deposition processes such as a screen printing process, one or more lithographical processes such as an etching process, a combination of deposition and lithographical processes, and the like.
  • [0042]
    FIG. 4 is a diagram of an exemplary capacitive sensing device 400 that illustrates selective disposing of substantially opaque conductive material in accordance with an embodiment of the present invention. It is noted that capacitive sensing device 400 can be fabricated in a manner similar to capacitive sensor patterns 300A and 300B of FIGS. 3A and 3B, respectively, as described herein. The solid lines of capacitive sensing device 400 represent the substantially opaque conductive material while the dashed lines represent the underlying substantially transparent conductive material within an “illumination” opening 402 of capacitive sensing device 400. In this manner, light is able to pass through opening 402 of capacitive sensing device 400 in order to illuminate one or more keys (e.g., 204) of a keypad (e.g., 206) associated with an electronic device (e.g., 100) while still providing capacitive sensing capabilities within opening 402 via the existing substantially transparent conductive material. It is understood that the underlying substantially transparent conductive material extends beneath the substantially opaque conductive material.
  • [0043]
    Within capacitive sensing device 400, the substantially opaque conductive material of shapes 308 a, 320 a, 314 a and 326 a have been selectively disposed in order to create opening 402. Additionally, substantially opaque conductive material shape 324 a has been selectively disposed such that it minimizes capacitive interference to conductive bridge 352 a. In this manner, one or more patterns of substantially opaque conductive material can be tailored in order to minimize capacitive interference with one or more conductive bridges (e.g., 352 a and/or 354). It should be understood for purpose of the present application the term “minimize capacitive interference” is intended to refer to disposing the conductive bridges in an orientation and location for reducing capacitive coupling between the conductive bridges and one or more proximate conductive sensor patterns.
  • [0044]
    Within FIG. 4, it is noted that the capacitive sensor patterns 302 a and 304 a of capacitive sensing device 400 operate in manner similar to capacitive sensor patterns 302 and 304 of FIGS. 3A and 3B, described herein.
