Description:
TECHNICAL FIELD 
     The present invention relates to the field of electronics, and, more particularly, to the field of finger sensors. 
     BACKGROUND 
     Fingerprint sensing and matching is a reliable and widely used technique for personal identification or verification. In particular, a common approach to fingerprint identification involves scanning a sample fingerprint or an image thereof and storing the image and/or unique characteristics of the fingerprint image. The characteristics of a sample fingerprint may be compared to information for reference fingerprints already in a database to determine proper identification of a person, such as for verification purposes. 
     A fingerprint sensor may be particularly advantageous for verification and/or authentication in an electronic device, and more particularly, a portable device, for example. Such a fingerprint sensor may be carried by the housing of a portable electronic device, for example, and may be sized to sense a fingerprint from a single-finger. 
     Where a fingerprint sensor is integrated into an electronic device or host device, for example, as noted above, it may be desirable to more quickly perform authentication, particularly while performing another task or an application on the electronic device. In other words, in some instances it may be undesirable to have a user perform an authentication in a separate authentication step, for example switching between tasks to perform the authentication.

     DETAILED DESCRIPTION 
     The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which preferred embodiments of the invention are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Like numbers refer to like elements throughout, and prime notation is used to refer to like elements in different embodiments. 
     Referring initially to  FIGS. 1 and 2 , an electronic device  20  is now described. The electronic device  20  illustratively includes a housing, for example, a portable housing  21 , and a processor  22  carried by the portable housing. The electronic device  20  is illustratively a mobile wireless communications device, for example, a cellular telephone. The electronic device  20  may be another type of electronic device, for example, a tablet computer, laptop computer, etc. 
     A wireless transceiver  25  is also carried within the housing  21  and coupled to the processor  22 . The wireless transceiver  25  cooperates with the processor  22  to perform at least one wireless communications function, for example, for voice and/or data. In some embodiments, the electronic device  20  may not include a wireless transceiver  25  or other wireless communications circuitry. 
     A touch display  23  is also carried by the portable housing  21  and is coupled to the processor  22 . The touch display  23  may be a liquid crystal display (LCD), for example, or may be another type of touch display, as will be appreciated by those skilled in the art. Further details of the touch display  23  are described below. 
     A memory  26  is also coupled to the processor  22 . The memory  26  is for storing finger matching biometric template data, for example. The memory  26  may store other or additional types of data, as will be appreciated by those skilled in the art. 
     As will be appreciated by those skilled in the art, the touch display  23  acts as both an input device and a display. As such, the touch display  23  cooperates with the processor  22  to perform one or more device functions in response to input. For example, a device function may include a powering on or off of the electronic device  20 , initiating communication via the wireless transceiver  25 , and/or performing a menu function based upon input to the touch display  23 . 
     More particularly, with respect to a menu function, the processor  22  may change the touch display  23  to show a menu of available applications based upon pressing or input to the touch display. Of course, other device functions may be performed based upon input to the touch display  23 . Other or additional finger-operated user input devices may be carried by the portable housing  21 , for example, a pushbutton switch  24 , which may be used for other and/or additional device functions as will be appreciated by those skilled in the art. 
     Referring now additionally to  FIG. 3 , the touch display  23  includes a display layer  41 , and a transparent conductive layer  42  thereon defining touch sensing pixels, as will be appreciated by those skilled in the art. The transparent conductive layer  42  may comprise indium-tin-oxide (ITO), for example. The transparent conductive layer  42  is illustratively carried by or coupled to an upper surface of the display layer  41 . However, in some embodiments, the transparent conductive layer  42  may be coupled to a lower surface of the display layer  41 . Also, in some embodiments, there may be more than one transparent conductive layer  42  carried by a respective surface of the display layer  41  or within one or more display layers, as will be appreciated by those skilled in the art. Of course, there may be more than one display layer and more than one transparent conductive layer independent of one another. 
     A lower transparent dielectric layer  43  is carried by the touch display  23 . The lower transparent dielectric layer  43  may be glass, for example. The lower transparent dielectric layer  43  is illustratively coupled to the touch display  23  by an adhesive layer  44 , for example, a polyimide layer. Other and/or additional types of adhesives may be used. In some embodiments, the lower transparent dielectric layer  43  and the adhesive layer  44  may be absent. 
     A finger biometric sensor  30  is carried by the touch display  23 . More particularly, the finger biometric sensor  30  is carried by the lower transparent dielectric layer  43  and extends partially over an upper surface of the transparent dielectric layer. Another adhesive layer  45  may be adjacent the finger biometric sensor  30  across the upper surface the touch display  23 , or more particularly, the transparent dielectric layer  43 . 
     The finger biometric sensor  30 , in cooperation with the touch display  23 , senses a user&#39;s finger  40  or an object placed adjacent the finger biometric sensor. When a user contacts the touch display  23 , for example, during a navigation function or other touch display input, data from the user&#39;s finger  40  is acquired, for example, for finger matching and/or spoof detection, as will be appreciated by those skilled in the art. 
     Referring additionally to  FIG. 4 , the finger biometric sensor  30  includes a finger biometric sensing layer  33 . The finger biometric sensing layer  33  includes an array of transparent conductive finger biometric sensing pixels  34  capacitively coupled to the transparent conductive layer  42  of the touch display  23 . The array of transparent conductive finger biometric sensing pixels  34  may be electric field biometric sensing pixels. The array of transparent conductive finger biometric sensing pixels  34  may also comprise ITO. Of course, the array of transparent conductive finger biometric sensing pixels  34  may be another material. 
     The finger biometric sensor  30  also includes switchable transparent conductive blocking areas  32  between the finger biometric sensing layer  33  and the transparent conductive layer  42  of the touch display  23 . The switchable transparent conductive blocking areas  32  may include ITO, for example. Of course the switchable transparent conductive blocking areas  32  may include other and/or additional materials. The switchable transparent conductive blocking areas  32  are switchable between blocking and reading states, as will be explained in further detail below. Illustratively, the switchable transparent conductive blocking areas  32   a - 32   d  are in the form of spaced apart rectangular patches extending in a first direction of the array of transparent conductive finger biometric sensing pixels  34  ( FIG. 4 ). The finger biometric sensing layer  33  and more particularly includes spaced apart rectangular patches or columns extending in a second direction opposite the switchable transparent conductive blocking areas  32  that define the array of transparent conductive finger biometric sensing pixels  34 . 
     Reading circuitry  50  is also coupled to the finger biometric sensor  30 . The reading circuitry  50  includes amplifiers  51 , for example, a respective amplifier for each column of the array of transparent conductive finger biometric sensing pixels  34 , coupled to the array of transparent conductive finger biometric sensing pixels. Each amplifier  51  may be a single-ended amplifier, for example. Of course, there may be any number of amplifiers  51 , including a single amplifier, as will be appreciated by those skilled in the art. The reading circuitry  50  also includes a respective switch  52   a - 52   d  coupled to each spaced apart rectangular patch of the switchable transparent conductive blocking areas  32   a - 32   d.    
     The reading circuitry  50  also includes a controller  53  coupled to the amplifiers  52  and the switches  52   a - 52   d . The controller  53  is configured to read consecutive rows of the array of transparent conductive finger biometric sensing pixels  34  and switch the switchable transparent conductive blocking areas  32   a - 32   d  beneath a row to be read to the reading state (e.g.  32   b ) while switching other switchable transparent conductive blocking areas to the blocking state (e.g.  32   a ,  32   c ,  32   d ). 
     For example, when a row is to be read or imaged, the switch  52   b  coupled to the switchable transparent conductive blocking areas  32   b , or rectangular patch, below the row is switched, for example, opened, so those areas are electrically floated. The touch sensing pixels of the transparent conductive layer  42  drive the row, for example, uniformly. The other switches  52   a ,  52   c ,  52   d  corresponding to areas  32   a ,  32   c ,  32   d  or rectangular patches that are not beneath the row to be read are switched, for example, closed, so that those areas are coupled to a reference voltage, for example a circuit ground. Those switchable transparent conductive blocking areas  32   a ,  32   c ,  32   d  may effectively block the drive signal. It should be noted that shielding at a far edge (e.g., relative to the reading circuitry  50 ) may not be as effective as desired as on a near edge due to the grounded switchable transparent conductive blocking areas  32   a - 32   d  linear resistance, as will be appreciated by those skilled in the art. 
     The finger biometric sensor  30  also includes a transparent dielectric layer  37  between the switchable transparent conductive blocking areas  32  and the finger biometric sensing layer  33 . The transparent dielectric layer  37  serves as a dielectric buffer so that the switchable transparent conductive blocking areas  32  and the array of transparent conductive finger biometric sensing pixels  34  do not short circuit. 
     A transparent dielectric cover layer  46  is over the finger biometric sensor  30  ( FIG. 3 ). The transparent dielectric cover layer  46  may be glass, for example, or may another transparent dielectric material. 
     Referring now to  FIG. 5 , in another embodiment, the finger biometric sensor  30 ′ extends over an entire upper surface of the touch display  23 ′. In other words, there is not an adhesive layer laterally adjacent the finger biometric sensor  30 ′. 
     Referring to  FIG. 6 , in another embodiment, the controller  53 ″ is configured for two-dimensional differential reading of the array of transparent conductive finger biometric sensing pixels  23 ″. In this embodiment, both horizontal and vertical difference measurements or readings are performed. In particular, for a horizontal difference, transparent conductive blocking areas  32   b ″ below a desired row, for example a single rectangular patch, is switched so that it is electrically floating. Local horizontal differences between the adjacent pixels B-D of the array of transparent conductive finger biometric sensing pixels are measured. To measure vertical differences, transparent conductive blocking areas  32   b ″,  32   c ″, for example, two adjacent spaced apart rectangular patches, are switched so that they are electrically floating. The local vertical differences between adjacent pixels A-B, C-D, of the array of transparent conductive finger biometric sensing pixels  34 ″ are measured. The vertical differences may be measured at an angle other than vertical. The angle can be accounted for in an integration process that converts the difference measurements, for example representing an image, back to a normal image, as will be appreciated by those skilled in the art. 
     However, it should be noted that one disadvantage of this configuration relative to the single-ended array embodiment described above with respect to  FIGS. 3-4 , for example, may be that higher linear resistance is generally in the sense lines. To adjust resistivity and coupling, for example, relatively thin or narrow transparent conductive traces  31 ″, for example ITO, that are part of an interconnect layer of the finger biometric sensor  30 ″ may be used and extend from each pixel of the array of transparent conductive finger biometric sensing pixels  34 ″ to sensing circuitry or other circuitry. 
     With respect to the relatively narrow transparent conductive traces  31 ″, it may be desirable, from a signal perspective, that the relatively narrow width be less than 5% of the width of each pixel of the array of transparent conductive finger biometric sensing pixels  34 ″. For example, assuming each pixel has a width of 25 microns, it may be particularly desirable that each corresponding transparent conductive trace  31 ″ be 1 micron wide (4%). A frequency response of the array of transparent conductive finger biometric sensing pixels  34 ″ and the transparent conductive traces  31 ″ is generally not that different from that of the embodiment described above with respect to  FIGS. 3-4 . Additionally, the linear resistance of the relatively narrow transparent conductive traces  31 ″ may be about 25-times that of the relatively wide pixels. The parasitic capacitance of the transparent conductive traces  31 ″ to adjacent transparent conductive traces may also be reduced by a similar ratio, as will be appreciated by those skilled in the art. 
     A method aspect is directed to a method of sensing a finger biometric using an electronic device  20  that includes a touch display  23  including at least one display layer  41 , and at least one transparent conductive layer  42  thereon defining touch sensing pixels. A finger biometric sensor  30  is also carried by the touch display. The method includes selectively switching a plurality of switchable transparent conductive blocking areas  32  of the finger biometric sensor  30  between blocking and reading states. The plurality of switchable transparent conductive blocking areas  32  are between a finger biometric sensing layer  33  of the finger biometric sensor  30  and the at least one transparent conductive layer  42  of the touch display  23 . The finger biometric sensing layer  30  includes an array of transparent conductive finger biometric sensing pixels  34  capacitively coupled to the at least one transparent conductive layer  42  of the touch display  23 . 
     It should be appreciated that while a touch display  23  that includes a display layer  41  and at least one transparent conductive layer  42  thereon defining touch sensing pixels is described herein, the touch display may have initially been a display without touch capability. In this case, the transparent conductive layer  42  may have initially been considered a display electrode to drive the display, which, as in the illustrated electronic device  20 , would become adapted to provide a relatively high resolution touch sensing function in addition to finger biometric sensing. 
     The present disclosure recognizes that personal information data, including biometric data, in the present technology, can be used to the benefit of users. For example, the use of biometric authentication data can be used for convenient access to device features without the use of passwords. In other examples, user biometric data is collected for providing users with feedback about their health or fitness levels. Further, other uses for personal information data, including biometric data, that benefit the user are also contemplated by the present disclosure. 
     The present disclosure further contemplates that the entities responsible for the collection, analysis, disclosure, transfer, storage, or other use of such personal information data will comply with well-established privacy policies and/or privacy practices. In particular, such entities should implement and consistently use privacy policies and practices that are generally recognized as meeting or exceeding industry or governmental requirements for maintaining personal information data private and secure, including the use of data encryption and security methods that meets or exceeds industry or government standards. For example, personal information from users should be collected for legitimate and reasonable uses of the entity and not shared or sold outside of those legitimate uses. Further, such collection should occur only after receiving the informed consent of the users. Additionally, such entities would take any needed steps for safeguarding and securing access to such personal information data and ensuring that others with access to the personal information data adhere to their privacy policies and procedures. Further, such entities can subject themselves to evaluation by third parties to certify their adherence to widely accepted privacy policies and practices. 
     Despite the foregoing, the present disclosure also contemplates embodiments in which users selectively block the use of, or access to, personal information data, including biometric data. That is, the present disclosure contemplates that hardware and/or software elements can be provided to prevent or block access to such personal information data. For example, in the case of biometric authentication methods, the present technology can be configured to allow users to optionally bypass biometric authentication steps by providing secure information such as passwords, personal identification numbers (PINS), touch gestures, or other authentication methods, alone or in combination, known to those of skill in the art. In another example, users can select to remove, disable, or restrict access to certain health-related applications collecting users&#39; personal health or fitness data. 
     Many modifications and other embodiments will come to the mind of one skilled in the art having the benefit of the teachings presented in the foregoing descriptions and the associated drawings. Therefore, it is understood that the invention is not to be limited to the specific embodiments disclosed, and that modifications and embodiments are intended to be included within the scope of the appended claims.
