## Background
FIELD OF THE DISCLOSURE
This invention relates to displays. Specifically, this invention relates to OLED-based displays.
BACKGROUND OF THE DISCLOSURE
Conventionally, entities transmitted documentation to a range of customers and/or other entities for various purposes. The documentation typically was transmitted via postal mail, email, fax, courier or any other suitable method. Some examples of transmitted documentation may include contracts, offers for sale, offers of credit, bills, requests for information, receipts, notices and account statements.
Often, by the time the customer and/or other entities received the documentation, the documentation had become moot or obsolete. Sometimes, transmitted documentation required a customer's signature and retransmission of the signed documentation back to the entity. Other times, a customer was required to enter timely information into the documentation and retransmit the documentation to the entity. Retransmission of the documentation from the customer to the entity may have been via scan and fax, scan and email, photo capture and email, postal mail or any other suitable method. Often, the retransmission did not occur within a relevant window of time.
Therefore, it would be desirable to have apparatus and methods that enable live OLED-based documentation and displays. It would be further desirable to enable transmission of information directly from such apparatus and methods to a sender independent of other transmission methods and/or apparatus.
SUMMARY OF THE DISCLOSURE
An OLED-based foldable display is provided. The OLED-based foldable display may include an array of organic light emitting diodes (“OLEDs”). The array of OLEDs may form the display. A portion of the array of OLEDs may have a surface area that is a percentage of an area of 8.5 by 11 square inches. The percentage may be 1%, 5%, 10%, 25%, 50%, 75%, 100% or any other suitable percentage of the area of 8.5 by 11 square inches. The array of OLEDs may further include a pressure-sensitive portion. The pressure-sensitive portion may be configured to capture a handwritten signature.
The display may include a wireless communication circuit. The display may include a processor circuit. The processor circuit may include a non-transitory memory and a processor. The display may also include a battery. The battery may power the OLED display, the pressure-sensitive portion, the wireless communication circuit and/or the processor circuit.
In operation, the processor circuit may be configured to control the OLED display, the pressure-sensitive portion and/or the wireless communication circuit by executing tasks or transmitting instructions to execute tasks. One task may include receiving a handwritten signature on the pressure-sensitive portion. Another task may include storing the handwritten signature in the non-transitory memory as a pixelated image.

DETAILED DESCRIPTION OF THE DISCLOSURE
An OLED-based foldable display may be provided. OLEDs are typically solid-state semiconductors constructed from a thin film of organic material. OLEDs emit light when electricity is applied across the thin film of organic material. Because OLEDs are constructed using organic materials, OLEDs may be safely disposed without excessive harm to the environment.
Furthermore, OLEDs may be used to construct a display that consumes less power compared to other display technologies. For example in a Liquid Crystal Display (hereinafter, “LCD”) power must be supplied to the entire backlight even to illuminate just one pixel in the display. In contrast, an OLED display does not include a backlight. Furthermore, in an OLED display only the illuminated pixel(s) draw power, which is preferable for mobile and battery-powered applications such as the current invention.
Therefore, power efficiency of OLED technology presents a possibility for designing OLED-based foldable displays.
The display may include an array of organic light emitting diodes (“OLEDs”). The array of OLEDs may form the display. The surface area of at least a portion of the OLED-based display may be at least 25% of an area defined by a width of 8.5 inches and a length of 11 inches. The surface area may be any other suitable percentage of any other suitable size display. For example, the surface area may be 5% of an area defined by a width of 20 inches and a length of 30 inches.
The array of OLEDs may include a pressure-sensitive portion. The pressure-sensitive portion may be configured to capture a handwritten signature. The pressure-sensitive portion may also be configured to capture one or more of a person's biometric characteristics. The one or more biometric characteristics may be a fingerprint, a toeprint and/or any other suitable biometric characteristic.
In some embodiments, a second pressure-sensitive portion may be configured to capture a person's biometric characteristic. In other embodiments, a biometric characteristic capture film may capture a person's biometric characteristic without the person's knowledge. In some embodiments, a camera, embedded in the display, may be configured to capture a person's biometric characteristic. The received biometric characteristic may be transferred into an array of bytes on the non-transitory memory. The array of bytes on the non-transitory memory may be transmitted to the secure entity hub together with a pixelated image.
The array of OLEDs may display information. Using OLEDs to display information may have several technical advantages. OLED displays may provide lower power consumption, wider viewing angles, better colors, higher contrast, operate in wider temperature ranges and enable faster refresh rates than other display technology. In some embodiments, OLED displays may be fabricated directly on control circuitry. OLED displays may only include trace amount of heavy metals. Thus, when disposed of, OLED displays may be less harmful to the environment than other display technology.
The display may include a communication circuit. The communication circuit may be configured to implement protocols for wireless communication. For example, the wireless communication circuit may provide Wi-Fi, NFC (near field communication), Bluetooth or any other suitable means of wireless communication. Wi-Fi may include passive Wi-Fi with lower power consumption than typical Wi-Fi. The communication circuit may have a thickness that is not greater than 0.8 mm.
The display may include a processor circuit. The processor circuit may be alternatively referred to herein as a software chip. The processor circuit may have a thickness that is not greater than 0.25 mm. The processor circuit may include a processor for controlling overall operation of the display and its associated components. The display may include RAM, ROM, one or more input/output (“I/O”) modules and one or more non-transitory or non-volatile memory components.
The I/O module may include a microphone, camera, pressure-sensitive portion, button and/or touch screen which may accept user provided input. The I/O module may include one or more of a speaker for providing audio output and a video display for providing textual, audiovisual, and/or graphical output. The video display may include one or more of the OLEDs.
Software may be stored within the non-transitory memory and/or other storage medium. The software may provide instructions to the processor for enabling the display to perform various functions. For example, the non-transitory memory may store software used by the display, such as an operating system, application programs and an associated database. Additionally, the information in the non-transitory memory may be encrypted to protect private information of the entity and its customer. Alternatively, some or all of the computer executable instructions of the display may be embodied in hardware or firmware components of the display.
Application programs, which may be used by the display, may include computer executable instructions for invoking user functionality related to communication, such as email, short message service (SMS), and voice input and speech recognition applications. Application programs may utilize one or more algorithms that request alerts, process received executable instructions, perform power management routines or other suitable tasks.
The OLED-based display may include a battery. The battery may be for powering the OLED display, the pressure-sensitive portion, the communication circuit and the processor circuit. The battery may have a thickness not greater than 0.5 mm.
In operation, the processor circuit may be configured to control the OLED display, the pressure-sensitive portion, the wireless communication circuit and the processor circuit by executing tasks or transmitting instructions to execute tasks. The tasks may include receiving a handwritten signature on the pressure-sensitive portion. The tasks may include storing the handwritten signature in the non-transitory memory as a pixelated image. The tasks may include storing, in the non-transitory memory, a date time value of the receipt time of the handwritten signature. The tasks may include, scanning, via the communication circuit, for a wireless communication network. The tasks may include transmitting, over the wireless communication network, the pixelated image, the date time value and an identification number associated with the display to a secure entity hub. The transmitting may be initiated upon detecting a wireless communications network.
In an exemplary embodiment, the display may include a contract. The contract may be mailed to a customer. The display may foldable. When trifolded the display may be sized to fit into a #10 standard envelope. The mailing may be in a #10 standard envelope. The mailing may be in any other suitable envelope or mailer. Upon opening the envelope or mailer, a potential customer may view the contract displayed on the OLED-based foldable display.
The OLED-based display may be solar-powered or light-powered. Upon opening the display, e.g., exposing the display to the sun or another source of light, the display may be “turned on.” In the event that the customer would like to execute the contract, the customer may sign the contract on the pressure-sensitive portion of the display. A pixelated image of the handwritten signature may then be transmitted from the communications circuit, via a detected wireless communications network, to the secure entity hub. The secure entity hub may be the contract's issuer. The secure entity hub may be a mailing entity associated with the contract's issuer.
An identification number associated with the display may be transmitted along with the handwritten signature. The identification number may enable the secure entity hub to determine what signature was received and from whom it was received.
In some embodiments, the secure entity hub may retain a record for each display that was sent. Each record may include what is displayed on the display, the identification number associated with the display and the entity, customer or person to which the display was mailed.
The secure entity hub may verify receipt of the signature. The secure entity hub may transmit the verification, via the wireless communication network, to the communication circuit. The verification may include the identification number and a message that the signature has been verified (and/or accepted) and the contract is valid. Upon receipt of the verification, the display may display the verification to the customer.
In some embodiments, in an attempt to perform fraud prevention, the signature may be denied. A denial may be transmitted to the display. This may occur when, upon comparison of the pixelated image to the secure entity hub's stored image (of the customer's signature), there exists a difference greater that a predetermined degree of accuracy.
Upon verification of the contract, the secure entity hub may mail the signed contract to the customer. In other embodiments, the secure entity hub may email the signed contract to the customer. In yet other embodiments, the secure entity hub may fax the signed contract to the customer.
In some embodiments, the signature may become imprinted or embossed upon the substrate, which may be paper, plastic, laminated poster or any other suitable substrate.
In some embodiments, the OLED-based display may include a portion of electrophoretic ink. Electrophoretic ink may preferably include bistable properties. A bistable image may be retained on a display even when all power sources are removed. Therefore, once the pixels in an electrophoretic display are set, the pixels are maintained on the display in the set order regardless of the power level of the display. Because of its bistable properties, electrophoretic ink may enable an OLED-based display to display the handwritten signature even after the display loses power. In an exemplary embodiment, this feature may enable a customer to sign a contract, receive signature verification and put the contract in safekeeping as physical proof of the contract; all without ever using—i.e., being preferably completely independent of—another method of communication with the secure entity hub.
In these embodiments, the array of OLEDs may be positioned above a layer of electrophoretic ink in a stacked architecture. This may enable the electrophoretic ink to be maintained even when the powerable OLED is no longer available. In some embodiments, the electrophoretic ink may be located only under a portion of the array of OLEDs. In yet other embodiments, the electrophoretic ink may be side-by-side with the OLED display. In still other embodiments, only the signature portion (pressure-sensitive portion) of the display may be formed from electrophoretic ink.
In some embodiments, the communication circuit may be configured to detect a second software chip. The software chip may be detected via NFC, Bluetooth, Wi-Fi or any other suitable communication method. The second software chip may be an EMV chip embedded in a credit card, debit card, bank card or any other suitable card. The second software chip may be a chip embedded in an identification card, such as, a driver's license, driver's permit, non-driver identification card, passport, employee identification card, student identification card or any other suitable card. The second software chip may be embedded in a cell phone, smartphone, tablet, laptop, or any other suitable device.
The OLED-based display may attempt to retrieve identification information from the second software chip. The identification information may include a name, address, telephone number, income bracket, social security number, tax identification number or any other suitable identification information. The wireless communication circuit may transmit the identification information to the secure entity hub. In some embodiments, the wireless communication circuit may transmit the identification information to the secure entity hub, via the user's wireless device. The device may be a smartphone. The secure entity hub may then transmit a packet to the OLED-based display comprising personalized display information. In some embodiments, the secure entity hub may transmit the packet, via cellular communications on the user's device, to the OLED-based display. The personalized display include may include, for example, a contract or offer personalized and/or customized for the potential customer or client.
In some embodiments, the OLED-based display may include a card blank. The card blank may be temporarily fastened to the display. The fastening may enable communications between the card and the display. The card blank may also be embedded in the display. The card blank, embedded in the display, may be electrically coupled to the display at one or more locations of the card blank's perimeter. The card blank's perimeter may perforated to enable a user to remove the card blank upon completion of a registration process. The perforated connections may form electrical connections to enable communications—i.e., electronic signals—between the OLED display and the card blank.
Upon transmission of A) identifying information received via communication with the second software chip; and B) a handwritten signature acknowledging the customer's agreement to the terms and conditions of the contract, the secure entity hub may transmit A) card blank information—i.e., information for transforming the card blank into an active credit card; B) acceptance of the handwritten signature; and C) the OLED-based identification number, to the OLED-based display. Upon receipt of these three segments of information, the OLED-based display may A) change the display of the card to include the card blank information; B) transmit the card blank information into a software chip located on the card blank; and C) write the card blank information to a magnetic strip located on the card blank; thereby, activating the card blank. The card blank may become activated to perform as a smart card.
A smart card may include an array of OLEDs. The array of OLEDs may have a thickness not greater than 0.25 mm. The array of OLEDs may have a surface area that is at least 90% of 85.60 mm×53.98 mm. The smart card may include a pressure-sensitive button. The pressure-sensitive button may have a thickness not greater than 0.8 mm. The smart card may include a wireless communication circuit. The wireless communication circuit may have a thickness not greater than 0.8 mm. The smart card may include a processor circuit. The processor circuit may include a non-transitory memory and a processor. The processor circuit may have a thickness that is not greater than 0.25 mm. The smart card may include a battery. The battery may be for powering the OLED display, the wireless communication circuit and the processor circuit. The battery may have a thickness that is not greater than 0.5 mm.
The OLED-based display may transmit a second packet to the secure entity hub. The packet may include the display identification number and a message that the card blank has been activated.
The customer may remove the card blank from the display in order to utilize the card blank. In some embodiments, the first time the customer utilizes the card blank, the card comprising the second software chip may be required as identification in order to utilize the card blank.

FIGS. 1A and 1B show an illustrative envelope. The envelope may be a #10 standard envelope. The envelope may be any other suitable size envelope. Inside the envelope may be an OLED-based display. The OLED-based display may be foldable in order to fit into a standard envelope.
Is some embodiments, if the substrate of the OLED-based display is not easily foldable, the OLED-based display may be hinged in a trifold manner in order to fold neatly into an envelope. The hinges may preferable enable the display to continue through the hinges. The hinges may be tape, plastic hinges, metal hinges or any other suitable hinges.
FIG. 2A shows illustrative OLED-based display 200. The OLED-based display may have been addressed to potential customer John Doe, as shown at text 202. Display 200 may attempt to encourage potential customer John Doe to sign up to participate in a gym membership, as shown at text 204. The terms of the contract may be printed on display 200, as shown at 206.
In the event that potential customer John Doe decides to purchase the gym membership and validate the contract, potential customer John Doe may sign on pressure-sensitive portion 210, as directed by text 208. John Doe's signature 212 may be signed using pen 214, or any other suitable instrument. The handwritten signature may be stored as a pixelated image in a non-transitory memory resident on display 200. A wireless communication circuit may transmit the pixelated image as well as an identification number associated with display 200 to a secure entity hub. The secure entity hub may be the entity that transmitted display 200 to John Doe.
Upon receipt of the pixelated image and the identification number at the secure entity hub, the secure entity hub may validate the gym membership. Signed display 200 may serve as proof of John Doe's gym membership.
FIG. 2B shows an exploded, cut-away, side view of illustrative display 200. Display 200 may include at least four layers. The four exemplary layers shown are A) encapsulation layer, B) organic layer, C) circuitry layer and D) substrate layer.
The encapsulation layer may protect the OLED layer from exposure to oxygen, water and other contaminants. Preferably, the encapsulation layer is flexible and transparent. Glass is a typical material for constructing an encapsulation layer. When glass is used to construct the encapsulation layer, 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, the encapsulation layer 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.
The organic layer may include an emissive solid-state semiconductor. The organic layer may be constructed from a thin film of organic (carbon-based) material. For example, the organic layer may include one or more OLEDs. When electricity is applied to an OLED within the organic layer, electrons flow through the organic layer 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 the organic layer may be controlled by the amount of electricity flowing through organic layer.
The organic layer may be doped with “host” materials. Host material may affect properties, such as power efficiency, of the organic layer. For example, the organic layer may be doped with emitter materials that improve its operation and/or achieve a desired color.
The organic layer may include two or more sub-layers (not shown). For example, the organic layer may include 5, 10 or 15 sublayers. Illustrative sub-layers may include: (1) an electron transport layer, (2) a blocking layer, (3) an emissive layer, (4) a hole transport layer and (5) an injection layer. The sub-layers 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 the organic layer 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 the circuitry layer and the substrate. The circuitry layer and substrate 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 the organic layer to be formed on a non-transparent substrate. Small-and medium-sized OLED displays (e.g., 1-7 inches) are typically constructed using top-emitting techniques.
Organic layer 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 may include stacking different color OLEDs on top of each other. OLEDs may be stacked because materials used to construct the organic layer may be transparent. A stacked design may provide a smaller pixel size and higher resolution.
Circuitry layer may include electronics that drive one or more pixels formed within the organic layer. Preferably, amorphous silicon (“a-Si”) and low temperature polysilicon (“LTPS”) may be used to construct the circuitry layer. In some embodiments, the circuitry layer may be transparent.
The substrate layer may support the circuitry layer, the organic layer and the encapsulation layer. The substrate layer may be constructed using various materials. For example, the substrate layer may be constructed using glass, plastic or metal materials. In some embodiments, such as in bottom-emitting OLEDs, the substrate layer may function as the encapsulation layer.
FIG. 3 shows a transparent view of OLED-based display 300. Display 300 may include software chip 306. Software chip 306 may include a processor and a non-transitory memory. Software chip 306 may control substantially all the operations of display 300. In some embodiments, OLED display may include a plurality of software chips.
Display 300 may also include communication circuit 308. Communication circuit 308 may enable communication from the display with another communicative device. Communication circuit 308 may enable communication via Wi-Fi, Bluetooth, NFC, SMS, cellular signals and/or other suitable communication method.
Display 300 may also include pressure-sensitive portion 304. Pressure-sensitive portion 304 may be included in the OLED screen. Pressure-sensitive portion 304 may retain an imprint, e.g., a handwritten signature, a stamp, a fingerprint, a toeprint or any other suitable imprint. The retained imprint translated into an image may be stored in software chip 306.
Display 300 may also include battery 302. Battery 302 may power the components of display 300. Battery 302 may be solar-powered and/or light-powered.
FIG. 4 shows an illustrative side view of an OLED display. It should be appreciated that the dimensions shown are for the purposes of illustration and not for limitation.

It should be appreciated that layers 500-900 may be stacked in any other suitable manner than that shown in FIG. 10. It should also be appreciated that not every layer may be necessary in every OLED-based display. Connections may exist between the components and/or layers of display 1000. For example, there may be wiring, circuitry or any other suitable connection to link together components of OLED-based display 1000.
FIGS. 11A-C show several states of illustrative OLED-based display 1100.
FIG. 11A shows that OLED-based display 1100 may be a credit card offer, as shown at 1102. OLED-based display 1100 may have been mailed and addressed to potential customer “John Doe”, as shown at 1106. The current date and time may be displayed, as shown at 1104. Text 1108 may inform potential customer “John Doe” that he is pre-approved for a credit card. Text 1108 may also inform potential customer “John Doe” of the terms and conditions of the credit card.
In the event that customer “John Doe” decides to accept the credit card offer, he may sign at box 1112. Box 1112 may be a pressure-sensitive portion configured to accept a signature. Card blank 1110 may be affixed to document. Card blank 1110 may be a smart card, as described earlier.
Upon signing document 1100, a pixelated image of the signature may be transmitted to a secure entity hub.
