Title: OLED (“organic light emitting diode”) teller windows

Description:
CROSS REFERENCE TO RELATED APPLICATION 
     This application is a continuation of U.S. patent application Ser. No. 15/187,972 filed on Jun. 21, 2016 and entitled “OLED (“ORGANIC LIGHT EMITTING DIODE”) TELLER WINDOWS” which is hereby incorporated by reference herein in its entirety. 
    
    
     FIELD OF THE INVENTION 
     This invention relates to teller windows. 
     BACKGROUND OF THE INVENTION 
     A teller window is a piece of glass, or other suitable substrate, that sits between a customer and a teller. In addition to enabling visual contact between the teller and the customer, teller windows also serve as a security barrier between a customer and a bank teller. 
     Teller windows may be located internal to—e.g., at a teller booth above a half-wall between a teller and customer, to enable visual contact between a teller situated inside a financial institution and a customer situated inside the financial institution—or external to—e.g., located on an external wall of a financial institution, to enable visual contact between a teller situated inside the financial institution and a customer situated outside the financial institution—a financial institution. External teller windows may be located on an external wall of a financial institution. External teller windows may serve as drive-up facilities in financial institutions. 
     Internal teller windows may be located inside financial institutions, at teller counters. At times, these windows reach from the ceiling to the teller counter. Other times, these windows may reach from the teller counter to the height of an average teller. 
     Sometimes, during a customer/teller transaction, a remote specialist may be required to complete the transaction. Other times, a teller may want to show transaction details to a customer while the transaction is being performed. 
     Therefore, it may be desirable for a teller window to be an OLED teller window. 
     SUMMARY OF THE DISCLOSURE 
     A method for enabling an OLED, drive-up, two-sided teller window is provided. The method may include establishing an initiation state. During the initiation state, the teller window may be transparent. 
     The method may also include detecting a car at the OLED, drive-up, teller window. The detection of the car may change the state of the window. 
     The method may include receiving banking information from a user of the car. The receipt of information may occur at the OLED, drive-up, teller window. The receipt of information may be via a pass-thru transaction drawer. 
     The method may include powering on a first portion of the OLED, drive-up teller window. The first portion may display transaction information. The transaction information may be associated with the user of the car. 
     The method may also include maintaining transparency of a second portion of the OLED, drive-up, teller window. The transparent second portion may enable a teller, located on a side of the window opposite from the user, to make visual contact with the user. 
     When a teller is unavailable, a user-side of the second portion may be powered on. The user-side of the second portion may display a remote teller. The remote teller may communicate with the user via audio and/or video input, such as Skype™, or any other similar technology. 
     The teller-side of the second portion may be powered on. The teller-side of the second portion may be used as a banking portal computer screen. 
     A teller may be able to toggle between viewing the computer screen on the second portion and viewing the user through the second portion. 
     A configurably-opaque layer may sit between the user-side and the teller-side of the two sided window. The configurably-opaque layer may be transparent when idle. Upon powering on of a user-side of the two-sided window and upon powering on of the teller-side of the two-sided window, the configurably-opaque layer may be powered on. 
     A user-side of the first portion may be configured to display a remote specialist to the user. A teller-side of the first portion may be configured to display the remote specialist to the teller.

     DETAILED DESCRIPTION OF THE DISCLOSURE 
     A method for enabling a four-pane, two-sided OLED window in a teller booth is provided. The four panes of the OLED window may be visible panes. The method may include establishing an initiation state. During the initiation state, the four panes of the OLED window may be transparent. 
     In some embodiments, during the initiation state, the two user-side panes may display advertisements. 
     The method may also include receiving banking information from a human being at a first pane of the OLED window. The banking information may be stored in the form of a debit card, bank card, deposit slip, withdrawal slip or any other suitable banking information. 
     The method may also include powering on a second pane of the OLED window. The second pane may be side-by-side with the first pane. The second pane may display transaction information to the human being. The transaction information may be associated with a transaction associated with the human being. 
     The method may also include enabling the first pane and a third pane to remain transparent to enable a teller to make visual contact with the human being. The third pane may be located in the rear of the first pane. The teller may be located on a side of a window opposite from the human being. 
     The method may also include powering on a fourth pane. The fourth pane may be located in the rear of the second pane. The fourth pane may display transaction information to the teller. 
     In some embodiments, the panes may be moveable. In these embodiments, a teller, or customer, may be able to roll one, or otherwise shift one or more panes and block the view of another pane. This may be the case when a customer or teller hands over documentation to the opposite party. 
     In certain embodiments, the first pane may be powered on. At times, a teller may be unavailable. Therefore, the first pane may display a remote teller. The remote teller may communicate via audio and/or visual input with the human being. The remote teller may perform the actions of a teller. The remote teller may be able to assist the human being to complete a transaction. 
     In some embodiments, the method may also include powering on a first configurably-opaque layer. The first configurably-opaque layer may sit between the first pane and the third pane. The first configurably-opaque layer may be powered on when both the first pane and the third pane are powered on. When powered on, the configurably-opaque layer may be opaque. Without power, the configurably-opaque layer may be transparent. The configurably-opaque layer may ensure that the display of the first pane and the display of the third pane do not interfere with each other—i.e., the teller-side can only view the third pane and the customer-side can only view the first pane. 
     In some embodiments, powering on the first configurably-opaque layer may depend on powering on either the first pane or the third pane. 
     In other embodiments, if both the first pane and the third pane are powered off, the configurably-opaque layer may be powered on. This may ensure privacy of the teller booth when a teller is present but unavailable. This may enable a teller to remain in a teller booth and not be available to assist or be visible to customers. Previously, when a teller was at his booth, customers would be able to view the teller and the customers would assume that the teller was available. The configurably-opaque layer may enable the teller to do paper work, eat lunch, or any other suitable action, at his teller booth, with privacy. 
     In other embodiments, a first configurably-opaque layer may be unnecessary. In these embodiments, when powered on, the OLED panes themselves may serve as a barrier and do not interfere with each other. 
     The method may also include powering on a second configurably-opaque layer. The second configurably-opaque layer may sit between the second pane and the fourth pane. Powering on of the second configurably-opaque layer may be dependent on the powering on of both the second pane and the fourth pane. In some embodiments, powering on the second configurably-opaque layer may be dependent on powering on either the second pane or the fourth pane. 
     In other embodiments, if both the second pane and the fourth pane are powered off, the configurably-opaque layer may be powered on. This may be to ensure privacy of the teller booth when the teller is unavailable. 
     In other embodiments, a second configurably-opaque layer may be unnecessary. In these embodiments, when powered on, the OLED panes themselves may serve as a barrier and do not interfere with each other. 
     In some embodiments, the fourth pane may be powered on and utilized as a computer screen. 
     In other embodiments, the teller can toggle between viewing the computer screen on the fourth pane and viewing the human being through the fourth pane. The toggling may be accomplished by powering on or off the configurably-opaque layer. 
     In yet other embodiments, the second pane may be configured to display a remote specialist to the human being. The fourth pane may be configured to display the remote specialist to the teller. At times, it may only be necessary for the teller to view the remote specialist. Other times, it may only be necessary for the human being to view the remote specialist. Other times, it may be necessary for both the teller and the human being to view the remote specialist. 
     Illustrative embodiments of apparatus and methods in accordance with the principles of the invention will now be described with reference to the accompanying drawings, which form a part hereof. It is to be understood that other embodiments may be utilized and structural, functional and procedural modifications may be made without departing from the scope and spirit of the present invention. 
     The drawings show illustrative features of apparatus and methods in accordance with the principles of the invention. The features are illustrated in the context of selected embodiments. It will be understood that features shown in connection with one of the embodiments may be practiced in accordance with the principles of the invention along with features shown in connection with another of the embodiments. 
     Apparatus and methods described herein are illustrative. Apparatus and methods of the invention may involve some or all of the features of the illustrative apparatus and/or some or all of the steps of the illustrative methods. The steps of the methods may be performed in an order other than the order shown or described herein. Some embodiments may omit steps shown or described in connection with the illustrative methods. Some embodiments may include steps that are not shown or described in connection with the illustrative methods, but rather shown or described in a different portion of the specification. 
     One of ordinary skill in the art will appreciate that the steps shown and described herein may be performed in other than the recited order and that one or more steps illustrated may be optional. The methods of the above-referenced embodiments may involve the use of any suitable elements, steps, computer-executable instructions, or computer-readable data structures.

       FIG. 1  shows an illustrative external OLED teller window  102 . A customer may drive up to teller window  102 . A teller (shown in  106 ) may make visual contact with a customer. The customer may want to perform a transaction. The customer may utilize pass-thru transaction drawer  110  to transmit and receive documentation from the teller. Light  104  may illuminate the teller window when necessary. 
     The teller may want to display transaction information to the customer. Therefore, OLED pane  108  may be powered on and display the information to the customer. It may be preferable that the OLED screen has glare-reducing properties to block glare-causing light. 
     The OLED screen may also include observation reduction abilities. Such abilities may preferably reduce the viewing cone that is associated with the display. They may make an image seem garbled, poorly saturated, or poor contrast, blurry or too faint outside a desired viewing angle range. For example, some screens reflect more light perpendicular to the screen and less light to the sides, making the screen appear much darker if the viewer is not in front of the screen. 
     The OLED pane  106  may remain transparent throughout the session to ensure communication and visual contact between the customer and the teller. 
       FIG. 2  shows another illustrative external OLED teller window. Window  202  may include OLED panes  204  and  206 . A customer may transfer and receive documentation via pass-thru transaction drawer  208 . 
     During a communication with the teller, a customer may wish to speak with a specialist or a supervisor. At times, a specialist or supervisor may be unavailable at the physical location of teller window  202 . Therefore, the teller may power on OLED pane  204 . A virtual specialist or supervisor may communicate with the customer, via OLED pane  204 . The virtual specialist or supervisor may also communicate with the teller via an OLED pane (not shown) that backs up to OLED pane  204 . 
     Also, at times a physical teller may be unavailable to assist a customer. Therefore, OLED pane  206  and/or OLED pane  204  may be powered on to display a remote teller which may assist a customer perform his desired transaction.

During the course of the communication, either teller  614  or customer  602  may want a third-party to join the communication. A third-party may be included for advertisement purposes—i.e., the customer may be interested in a home loan product and a third-party can introduce the options to the customer. A third-party may also be included for mediation purposes—i.e., if a customer is upset about the transaction and the teller is unable to rectify the situation, a third-party supervisor may rectify the situation. A third-party may also be included to on-board a new hire. In this instance, the third-party may only be visible on the teller side. A third-party may be included for any other suitable purpose. 
     As shown in  FIG. 6 , a remote specialist may be shown on OLED pane  604 . The remote specialist may be physically at another location, such as a call center, and be shown on OLED pane  604 .

       FIG. 9  shows a transparent perspective view of an OLED teller window with a configurably-opaque layer. Configurably-opaque layer  910  may be powered on when both OLED A  902  and OLED B  906  are powered on. This may ensure that a viewer of either OLED A  902  or OLED B  906  are not disturbed by the rear OLED screen. When powered on, configurably-opaque layer  910  may be opaque. When powered off, configurably-opaque layer  910  may be translucent. 
     Configurably-opaque layer  912  may be powered on when both OLED C  904  and OLED D  908  are powered on. This may ensure that a view of either OLED C  904  or OLED D  908  are not disturbed by the rear OLED screen. When powered on, configurably-opaque layer  912  may be opaque. When powered off, configurably-opaque layer  912  may be translucent. 
       FIG. 10  shows a transparent perspective view of a teller window without a configurably-opaque layer. In this embodiment, the powered on OLED screen itself may serve as a barrier to the rear OLED screen and may ensure that a viewer of the OLED screen is not disturbed by the rear OLED screen.

OLED C  1006  may back up with OLED D  1008 . 
       FIG. 11  shows an illustrative cutaway view of a two OLED screens with a configurably-opaque layer deployed in between. Each OLED screen may include four layers, encapsulations layers  1102  and  1118 , organic layers  1104  and  1116 , circuitry layers  1106  and  1114  and substrate layers  1108  and  1112 . Encapsulation layers  1102  and  1118  protect the OLED layer from exposure to oxygen, water and other contaminants. Preferably, encapsulation layers  1102  and  1118  are transparent. Glass is a typical material for constructing encapsulations layers  1102  and  1118 . 
     At times, when glass is used to construct encapsulation layers  1102  and  1118  the glass may be very thin and flexible. For example, the glass may be between 50 micrometers (μm) and 100 μm thick. 
     In some embodiments, encapsulations layers  1102  and  1118  may be constructed using thin-film encapsulation techniques such as Atomic Layer Deposition (“ALD”). ALD is a process that utilizes chemicals that, when deposited on a material, react to create a solid, thin film. 
     Organic layers  1104  and  1116  typically include an emissive solid-state semiconductor. Organic layers  1104  and  1116  may be constructed from a thin film or organic (carbon-based) material. For example, organic layers  1104  and  1116  may include one or more OLEDs. When electricity is applied to an OLED within organic layers  1104  and  1116 , electrons flow through organic layers  1104  and  1116  and release photons, thereby emitting light. Different types of emissive materials may be used. Each type of material may be associated with a different color light. An intensity of light emitted by organic layers  1104  and  1116  may be controlled by the amount of electricity flowing through organic layers  1104  and  1116 . 
     Organic layers  1104  and  1116  may be doped with “host” materials. Host materials may affect properties, such as power efficiency, of organic layers  1104  and  1116 . For example, organic layers  1104  and  1116  may be doped with emitter materials that improve its operation and/or achieve a desired color. 
     Organic layers  1104  and  1116  may include two or more sublayers (not shown). For example, organic layers  1104  and  1116  may include 5, 10 or 15 sublayers. Illustrative sublayers may include an electronic transport layer, a blocking layer, an emissive layer, a hole transport layer and an injection layer. The sublayers may enhance an efficiency of the emissive layer. 
     For example, an emissive layer may be placed between a cathode and an anode. When electricity is applied, electrons flow from the cathode to the anode. OLED displays may be driven by either electrical current or voltage. In a preferred embodiment, the OLED display is driven by current. The cathode inserts electrons into the emissive layer, and the anode removes the electrons. The electron “flow” through the emissive layer releases photons, generating light. The color of the generated light may be changed by including different types of materials within the emissive layer. 
     A direction of light emitted by organic layers  1104  and  1116  may be controlled by a degree of transparency of the anode and/or cathode. In some embodiments, a cathode may be reflective. Such a cathode may be constructed using an aluminum-based compound or lithium fluoride. An anode may be transparent. A transparent anode may preferably be constructed using indium tin oxide. In such embodiments, when current flows between the cathode and anode, light is emitted through circuitry layers  1106  and  1114  and substrate layers  1108  and  1112 . Circuitry layers  1106  and  1114  and substrate layers  1108  and  1112  may be transparent. Such embodiments may be referred to as “bottom-emitting OLEDs.” 
     In some embodiments, the cathode may be transparent. Such a cathode may preferably be constructed using indium tin oxide. The anode may be reflective. The reflective anode may direct light toward the transparent cathode. Such embodiments may be referred to as “top-emitting OLEDs.” Typically, top-emitting designs are more efficient and are used to construct higher resolution displays. 
     Additionally, top-emitting designs may allow organic layers  1104  and  1116  to be formed on a non-transparent substrate. 
     Organic layers  1104  and  1116  may form one or more pixels. Different architectures are available for forming pixels using OLEDs. One architecture includes positioning different color (e.g., red, green and blue) OLEDs adjacent to each other. Another architecture includes stacking different color OLEDs on top of each other. OLEDs may be stacked because materials used to construct organic layers  1104  and  1116  may be transparent. A stacked design may provide a smaller pixel size and higher resolution. 
     Circuitry layers  1106  and  1114  may include electronics that may drive one or more pixels formed within organic layers  1104  and  1116 . Preferably, amorphous silicon (a-Si) and low temperature polysilicon (LTPS) may be used to construct circuitry layers  1106  and  1114 . In some embodiments, circuitry layers  1106  and  1114  may be transparent. 
     Substrate layers  1108  and  1112  may support circuitry layers  1106  and  1114 ; organic layers  1104  and  1116 ; and encapsulation layers  1102  and  1118 . Substrate layers  1108  and  1112  may be constructed using various materials. For example, substrate layers  1108  and  1112  may be constructed using glass, plastic or metal materials. In some embodiments, such as in bottom-emitting OLEDs, substrate layers  1108  and  1112  may function as encapsulation layers  1102  and  1118 . 
     Configurably-opaque layer  1110  may function as a barrier between the first OLED and the second OLED. The configurably-opaque layer may be transparent when not in use and opaque when in use. 
     Thus, methods and apparatus for OLED teller windows are provided. Persons skilled in the art will appreciate that the present invention can be practiced by other than the described embodiments, which are presented for purposes of illustration rather than of limitation, and that the present invention is limited only by the claims that follow.
