Description

    RELATED APPLICATIONS
  • The present application is a Continuation of co-pending U.S. patent application Ser. No. 12/914,812 filed on Oct. 28, 2010, the disclosure of which is incorporated by reference herein. That application also claims the benefit of U.S. Provisional Application No. 61/256,908, filed Oct. 30, 2009, the disclosure of which is incorporated by reference herein.
  • BACKGROUND
  • Since its inception, fingerprint sensing technology has revolutionized identification and authentication processes. In most cases, a single fingerprint can be used to uniquely identify an individual in a manner that cannot be easily replicated or imitated. The ability to capture and store fingerprint image data in a digital file of minimal size has yielded immense benefits in fields such as law enforcement, forensics, and information security.
  • However, the widespread adoption of fingerprint sensing technology in a broad range of applications has faced a number of obstacles. Among these obstacles is the need for a separate and distinct apparatus for capturing a fingerprint image, which most consumer-grade computer systems do not contain. Incorporating a distinct component whose only function is to capture fingerprint image data into an otherwise multi-functional computer system is often not economical for consumers or computer manufacturers. Although low-cost fingerprint sensing devices do exist, consumers are often reluctant to purchase a separate accessory with such a limited application. Consequently, computer manufacturers typically do not incorporate such accessories as built-in components.
  • Additionally, such components are often impractical for use in systems that are designed to be of minimal size or weight. As handheld devices begin to take on a greater range of functionality and more widespread use, engineers and designers of such devices are constantly seeking ways to maximize sophistication and ease of use while minimizing size and cost. Typically, such devices only incorporate input/output components that are deemed to be essential to core functionality, e.g., a display screen, a keyboard, and a limited set of buttons.
  • For these reasons, fingerprint-based authentication techniques have not replaced username and password authentication in the most common information security applications such as email, online banking, and social networking. Paradoxically, the growing amount of sensitive information Internet users are entrusting to remote computer systems has intensified the need for authentication procedures that are more reliable than password-based techniques.
  • The advent and widespread adoption of LCD (Liquid Crystal Display) technology provides an opportunity to address this need. LCD technology provides a low-cost and versatile means of incorporating both input and output functionality into a single discrete component. Touch-screen technology, which typically comprises a special layer within the LCD panel apparatus, enables system output to be displayed and user input to be taken on the same surface. LCD technology has replaced cathode ray tube (CRT) displays in virtually all computer systems due to its lower power consumption and physical space requirements. Additionally, the declining cost and increasing sophistication of LCD touch-screen displays have contributed to the growing popularity of handheld computing devices incorporating such displays.
  • An LCD display with built-in fingerprint sensing capability would thus lead to more widespread adoption of fingerprint-based authentication. However, one problem with simply integrating existing fingerprint sensing technology into LCD touch screens is hardware incompatibility. Most fingerprint sensors require a silicon circuit on which to mount the fingerprint sensing components, whether they are resistive, capacitive, thermal, or optical. Incorporating such a circuit into an LCD display would require significant and costly modifications to the design and production processes of such displays. However, a fingerprint sensing system comprising a mechanism and components that can easily be incorporated into existing LCD display structures addresses this problem.
  • As will be seen, the present invention provides such a system in an elegant manner.

  • DETAILED DESCRIPTION
  • The present invention is directed to a novel fingerprint sensor that can be integrated with an LCD display structure, such as being positioned on or adjacent the LCD glass. Additionally, one or more fingerprint sensing elements can optionally replace a touch-screen controller chip to provide a single chip solution that provides both touch-screen functions and fingerprint sensor functions.

  • The embodiments discussed herein generally relate to an apparatus, system and methods for configuring fingerprint sensors and, in particular, for integrating fingerprint sensors into LCD circuits and displays. Referring to the figures, exemplary embodiments will be described. The exemplary embodiments of the invention are provided to illustrate the embodiments and should not be construed as limiting the scope of the embodiments.
  • In the following disclosure, numerous specific details are set forth to provide a thorough understanding of the invention. However, those skilled in the art will appreciate that the invention may be practiced without such specific details. In other instances, well-known elements have been illustrated in schematic or block diagram form in order not to obscure the invention in unnecessary detail. Additionally, for the most part, details concerning network communications, data structures, and the like have been omitted inasmuch as such details are not considered necessary to obtain a complete understanding of the invention, and are considered to be within the understanding of persons of ordinary skill in the relevant art.
  • It is further noted that all functions described herein may be performed in either hardware or software, or a combination thereof, unless indicated otherwise. Certain terms are used throughout the following description and claims to refer to particular system components. As one skilled in the art will appreciate, components may be referred to by different names. This document does not intend to distinguish between components that differ in name, but not function. In the following discussion and in the claims, the terms “including”, “comprising”, and “incorporating” are used in an open-ended fashion, and thus should be interpreted to mean “including, but not limited to . . . ”. Also, the term “couple” or “couples” is intended to mean either an indirect or direct electrical or communicative connection. Thus, if a first device couples to a second device, that connection may be through a direct connection, or through an indirect connection via other devices and connections.
  • While certain exemplary embodiments have been described and shown in the accompanying drawings, it is to be understood that such embodiments are merely illustrative of and not restrictive on the broad invention, and that this invention not be limited to the specific constructions and arrangements shown and described, since various other modifications may occur to those ordinarily skilled in the art. Accordingly, the specification and drawings are to be regarded in an illustrative rather than a restrictive sense.
  • Reference in the specification to “an embodiment,” “one embodiment,” “some embodiments,” or “other embodiments” means that a particular feature, structure, or characteristic described in connection with the embodiments is included in at least some embodiments, but not necessarily all embodiments. The various appearances of “an embodiment,” “one embodiment,” or “some embodiments” are not necessarily all referring to the same embodiments. If the specification states a component, feature, structure, or characteristic “may”, “might”, or “could” be included, that particular component, feature, structure, or characteristic is not required to be included. If the specification or claim refers to “a” or “an” element, that does not mean there is only one of the element. If the specification or claims refer to “an additional” element, that does not preclude there being more than one of the additional element.
  • The apparatus and method include a method and apparatus for enabling the invention. Although this embodiment is described and illustrated in the context of devices, systems and related methods of capturing fingerprints, the scope of the invention extends to other applications where such functions are useful. Furthermore, while the foregoing description has been with reference to particular embodiments of the invention, it will be appreciated that these are only illustrative of the invention and that changes may be made to those embodiments without departing from the principles, the spirit and scope of the invention, the scope of which is defined by the appended claims, their equivalents, and also later submitted claims and their equivalents.
  • As described in the background, the integration of most fingerprint sensor designs with an LCD screen is problematic due to the difficulty of incorporating a silicon-based sensor into an LCD display structure. According to the invention, this problem is obviated with a novel design that allows the fingerprint sensor to be positioned on or adjacent the LCD screen, on a side opposite the touch screen circuitry. The invention works with current touch-screen and LCD manufacturing techniques, where fingerprint sensor conductive components may be positioned on as surface opposite the layers of the LCD components. The fingerprint sensor is functionally integrated with other LCD control circuits or components. This provides an LCD panel with the added functionality of a fingerprint sensor without disrupting the operation of the visual display components. In addition, current LCD manufacturing techniques can easily be adapted to produce an LCD panel designed and configured according to the invention.
  • Consistent with the foregoing, disclosed herein is a fingerprint swipe sensor, comprising a substrate having fingerprint sensor lines on one surface and configured to be integrated with (or disposed adjacent to) an LCD screen, and a controller communicating with the fingerprint sensor lines to capture a fingerprint image when a user's finger is swiped about the fingerprint sensor lines. In one embodiment, the substrate is mounted on a surface of an LCD screen opposite the touch screen circuitry. In another embodiment, the substrate is positioned adjacent to a surface of the LCD screen opposite the touch screen circuitry.
  • Also disclosed is an LCD screen having an integrated fingerprint swipe sensor, comprising an LCD surface configured to produce a visible display, a substrate having fingerprint sensor lines on one surface and configured to be integrated with (or disposed adjacent to) the LCD screen to allow the integrated fingerprint sensor lines to capture a fingerprint image, and a controller communicating with the fingerprint sensor lines to capture a fingerprint image when a user's fingerprint is swiped about the fingerprint sensor lines. In one embodiment, the controller may be further configured to control the visible display. In another embodiment, the LCD screen may further comprise an additional controller configured to control the visible display.
  • As will be seen, the invention provides a mechanism to integrate the fingerprint sensor in an LCD opposite the components that are conventionally used in assembling touch-screen layers on LCD displays, or directly onto the LCD display itself. The examples and embodiments described herein include illustrations and references to touch sensitive circuitry, both capacitive and resistive, and also refer to fingerprint sensor circuitry that may also be capacitive or resistive, but the invention is not limited to any particular configuration or underlying technology in these areas. The invention is only limited by the appended claims, claims presented in the future, and any equivalents.
  • In current touch screen designs, there typically exists an LCD printed circuit board (PCB) on which the touch screen circuitry is mounted, and a protective shield or coating is applied on top of the touch screen circuitry. The touch screen circuitry is connected with the LCD display on the LCD PCB (Printed Circuit Board) by one of two methods. In one method, the touch screen circuitry is first mounted on the LCD PCB, then the protective shield or coating is applied on top of the touch screen circuitry. In another method, the touch screen circuitry is applied onto the protective coating or shield, and then the resulting structure is mounted on the LCD PCB, with the touch screen circuitry mounted between the protective coating or shield and the LCD PCB. According to the invention, the substrate of the fingerprint sensor can be positioned on an opposite surface of the LCD with either of these methods.
  • In the following figures, several examples of devices or systems configured according to the invention are illustrated.
  • Referring to FIG. 1, a diagrammatic view of an example LCD panel 100 having a printed circuit board (PCB) 102 for holding LCD components to provide a display. LCD panel 100 also includes optional touch screen circuitry 104 surrounded by a bezel portion 106. Bezel 106 is relatively narrow on three sides of touch screen circuitry 104, and wider along a fourth side, which includes a fingerprint sensor 108 with a swiping area 110 for capturing a fingerprint from a user. In this example, fingerprint sensor 108 is located outside the touch screen portion of LCD panel 100. As discussed herein, fingerprint sensor 108 can be positioned on the opposite surface of LCD panel 100 from touch screen circuitry 104.
  • LCD panel 100 can be manufactured in a number of ways and, given this disclosure, one skilled in the art will find it feasible to design and produce such a device without undue experimentation. LCD panel 100 may be utilized in a variety of devices, such as a computing device, cellular phone, portable entertainment device, tablet device, and so forth.
  • Referring to FIG. 2, a side diagrammatic view of a device 200 is illustrated with a top coating 202 (also referred to as a “protective layer”) having touch sensor circuitry 204 located on an inside portion of top coating/layer 202. A fingerprint sensor 206, layer described in greater detail below, is shown with a layer peeled back to illustrate the fingerprint sensor integrated with the LCD's PCB 208. As discussed herein, fingerprint sensor 206 may be positioned on a surface of PCB 208 that is opposite the surface on which touch sensor circuitry 204 is located.
  • FIG. 3 illustrates an exploded view of an example assembly 300, including an LCD PCB 302 and a fingerprint sensor 310. In this example, a mask 304 is applied to a surface of LCD PCB 302. Mask 304 is any material covering a portion of LCD PCB 302 that does not display images or other data. For example, mask 304 may include a black layer that is opaque or semi-transparent. Alternatively, mask 304 may include an ink or other colored pigment coating applied to LCD PCB 302, or applied to another layer, such as a protective layer or polyimide.
  • A protective layer 306, which includes touch screen circuitry 308 on one side of the protective layer is applied to mask 304. Touch screen circuitry 308 may be applied to the entire protective layer 306, or applied to the portion of the protective layer that aligns with the viewable opening in mask 304. In conventional assemblies, touch screen circuitry 308 may be adhered to or otherwise placed on the bottom side of protective layer 306 prior to assembly, and then placed or otherwise mounted on top of LCD PCB 302 during final assembly. In other assembly methods, touch screen circuitry 308 may be assembled onto mask 304, then the next layer (protective layer 306) is placed on top of the LCD PCB having touch screen circuitry 308 and mask 304 already mounted thereon.
  • Fingerprint sensor 310 has a swiping area 312. In one embodiment, swiping area 312 is indicated on mask 304 by a swipe area marking 316. Since the bezel portion of mask 304 may visually obscure fingerprint sensor 310, swipe area marking 316 is provided on mask 304 to indicate the desired fingerprint swiping area to the user of assembly 300. In a particular implementation, swipe area marking 316 uses a color or other characteristic that distinguishes the swipe area marking from the bezel color (or mask color). For example, if the bezel color is black, swipe area marking 316 is a lighter color, such as white or silver. In the example of FIG. 3, fingerprint sensor 310 is located on the opposite side of LCD PCB 302 from mask 304 and protective layer 306. Protective layer 306 can be a polyimide such as PET or PEN, or hard coat chemicals that can be applied to the surface of LCD PCB 302. In a particular embodiment, fingerprint sensor 310 is bonded to LCD PCB 302 using an optically clear adhesive (OCA) or other bonding mechanism. In an alternate embodiment, fingerprint sensor 310 is positioned on the same side of LCD PCB 302 as mask 304 and protective layer 306.
  • FIG. 4 illustrates a side view of an example LCD display device 400. The example of FIG. 4 shows an LCD PCB 402 with a mask layer 404 applied to one side of the LCD PCB. Touch screen circuitry 406 is then applied on mask layer 404 and a protective layer 408 is applied on the touch screen circuitry. Additionally, a fingerprint sensor 410 is applied to a side of LCD PCB 402 that is opposite mask layer 404. In this configuration, fingerprint sensor 410 senses a user's fingerprint as they swipe their finger about the fingerprint sensor.
  • FIG. 5 illustrates a side cut-away view of an example device 500 including a touch screen and a fingerprint sensor. Device 500 includes a housing 502, a printed circuit board 504 and an LCD module 506. The device also includes a glass layer 508 onto which indium tin oxide (ITO) or similar materials are applied to form the touch screen circuitry. The ITO is shown on opposite sides of glass layer 508 by reference numerals 512 and 514. Device 500 further includes a layer of protective glass 510 positioned above the ITO layer 512. A touch circuit controller 516 is coupled to ITO layers 512 and 514 via a flexible circuit 518. A fingerprint sensor 520 is coupled to printed circuit board 504 and positioned below the glass layer 508. Fingerprint sensor 520 senses fingerprint characteristics of a finger swiped along the surface of protective glass 510 proximate the fingerprint sensor. In a particular embodiment, layers 508 and 510 are non-conductive layers (e.g., glass). Fingerprint sensor 520 is capable of sensing ridges and valleys of a user's finger through layers 508 and 510. In a particular implementation, the distance from fingerprint sensor 520 to the surface of protective glass 510 (where the user swipes their finger) is 150 microns or less.
  • FIG. 6 illustrates a side cut-away view of another example device 600 including a touch screen and a fingerprint sensor. Device 600 includes a housing 602, a printed circuit board 604 and an LCD module 606. Device 600 also includes a glass layer 608 onto which ITO or similar materials are applied to form the touch screen circuitry. An ITO layer 612 is shown as applied to one side of glass layer 608. Device 600 further includes a protective layer 610 positioned above glass layer 608. A touch circuit controller 614 is coupled to ITO layer 612 via a flexible circuit 616. A fingerprint sensor 618 is coupled to printed circuit board 604 and positioned below glass layer 608. Fingerprint sensor 618 senses fingerprint characteristics of a finger swiped along the surface of protective layer 610 proximate the fingerprint sensor.
  • FIG. 7 illustrates an example method of assembling an LCD display device 700. The components shown in FIG. 7 are similar to those discussed above with respect to FIG. 3, where touch screen circuitry 714 is shown separately from a protective layer 716 prior to assembly. During the assembly process, a mask layer 704 is applied to a surface of LCD PCB 702. A fingerprint sensor 718 having a swiping area 720 is applied to the opposite surface of LCD PCB 702. In an alternate embodiment, fingerprint sensor 718 is positioned proximate the opposite surface of LCD PCB 702 on its own PCB or other structure.
  • As shown in FIG. 7, mask layer 704 includes an opening 708 that substantially aligns with a touch-sensitive portion of LCD display device 700. A bezel portion 706 of mask layer 704 includes a swipe area marking 710 that indicates the desired fingerprint swiping area to the user of the device. In the example of FIG. 7, a touch screen layer 712 includes touch screen circuitry 714 disposed thereon. Protective layer 716 is then applied to touch screen layer 712 to protect touch screen circuitry 714 and other components of LCD display device 700.
  • FIG. 8 illustrates another example method of assembling an LCD display device 800. During the assembly process, a touch screen layer 804 having touch screen circuitry 806 thereon, is positioned above an LCD module 802. Next, a protective layer 808 is placed over touch screen layer 804 to protect touch screen circuitry 806. A fingerprint sensor 810 is positioned proximate a surface of LCD module 802 opposite touch screen layer 804.
  • Referring to FIG. 9, a diagrammatic view of a sensing device 900 configured according to the invention is illustrated. The device includes a linear array 912 such as described in the embodiments above, and also includes a sensor element 902. The device further includes sensor control logic 952 configured to control the basic operations of the sensor element. The exact operations of the sensor element governed by the sensor logic control greatly depends on a particular sensor configuration employed, which may include power control, reset control of the pixels or data contact points, output signal control, cooling control in the case of some optical sensors, and other basic controls of a sensor element. Sensor controls are well known by those skilled in the art, and, again, depend on the particular operation.
  • Sensing device 900 further includes a readout circuit 954 for reading analog output signals from sensor element 902 when it is subject to a fingerprint juxtaposed on a sensor surface 907. Readout circuit 954 includes an amplifier 956 configured to amplify the analog signal so that it can more accurately be read in subsequent operations. A low pass filter 958 is configured to filter out any noise from the analog signal so that the analog signal can be more efficiently processed. Readout circuit 954 further includes an analog to digital converter 960 that is configured to convert the output signal from sensor element 902 to a digital signal that indicates a series of logic 0's and 1's that define the sensing of the fingerprint features by the pixels or data contact points of sensor surface 907. Such signals may be separately received by the motion sensors and the fingerprint sensing surfaces, and may be read out and processed separately.
  • Readout circuit 954 may store the output signal in a storage 962, where fingerprint data 964 is stored and preserved, either temporarily until a processor 966 can process the signal, or for later use by the processor. Processor 966 includes an arithmetic unit 968 configured to process algorithms used for navigation of a cursor, and for reconstruction of fingerprints. Processing logic 970 is configured to process information and includes analog to digital converters, amplifiers, signal filters, logic gates (all not shown) and other logic utilized by a processor. A persistent memory 974 is used to store algorithms 976 and software applications 978 that are used by processor 966 for the various functions described above, and in more detail below. A system bus 980 is a data bus configured to enable communication among the various components contained in sensing device 900.
  • In assembly, there are various ways such a device can be configured. In one embodiment, a fingerprint sensor is provided that includes a flexible substrate having fingerprint sensor lines on one surface and configured to be integrated with an LCD screen. This allows for a device such as a laptop, cellular phone, touch-screen interface, or other personal device to have an integrated fingerprint sensor, saving space and simplifying the integrated design.
  • In another embodiment, the fingerprint sensor may be mounted on the LCD PCB separate from the touch screen circuitry. The touch screen circuitry may be mounted on the protective shield or coating. The resulting structure can then be mounted on the LCD PCB. This also provides an LCD screen with both touch screen circuitry and fingerprint sensor circuitry integrated therein.
  • In yet another embodiment, the substrate is obviated by the protective coating. The protective coating is configured to hold touch screen circuitry together with the fingerprint sensor lines mounted on the protective coating or shield. Here, the protective coating can be mounted on an LCD screen together with the touch screen circuitry and the fingerprint sensor lines. In yet another combination, the touch screen circuitry can be mounted directly on the LCD PCB, the fingerprint sensor lines mounted on the protective coating or shield, and the two resulting structures can be mounted together to produce an LCD display having both touch screen and fingerprint sensor functionality.
  • The resulting system is an LCD screen having an integrated fingerprint swipe sensor and, possibly, a touch screen. The LCD screen may have one or the other or both, depending on the application. The system includes an LCD surface configured to produce a visible display. On top of the LCD surface can be mounted touch screen circuitry that may include fingerprint sensor lines. Alternatively, a separate substrate holding the fingerprint sensor lines may be mounted on or below the touch screen circuitry. In either configuration, the resulting structure may be configured to be integrated with the LCD screen to allow the integrated fingerprint sensor lines to capture a fingerprint image without interfering with the visibility of the display or with the function of the touch screen operation.
  • The system further includes a controller communicating with the fingerprint sensor lines to capture a fingerprint image when a user's fingerprint is swiped about the fingerprint sensor lines. In one system, there may be separate controllers for both the LCD display and the fingerprint sensor, where the system includes an LCD controller configured to control the visible display separate from the fingerprint sensor operations. Alternatively, the same controller may also control both the visible display and the fingerprint sensor operations. The fingerprint sensor could also be patterned onto the top glass of the LCD display itself, and not onto the touch-screen layer.
