Detailed Description
Reference will now be made in detail to exemplary embodiments of the invention, examples of which are illustrated in the accompanying drawings. Further, wherever possible, the same reference numbers will be used throughout the drawings and the description to refer to the same or like parts.
Fig. 1 is a schematic diagram of an electronic paper display device according to an embodiment of the invention. Referring to fig. 1, in the present embodiment, an electronic paper display device 100 includes an electronic paper display panel 110 and a display driver 120. The e-paper display panel 110 is driven by the display driver 120 to display a first image frame or a second image frame. In the embodiment of the invention, the electronic paper display panel 110 uses black display particles and white display particles as display media, respectively. In the present embodiment, for example, a black image screen and a white image screen displayed on the electronic paper display panel 110 are respectively used as an example of the first image screen and the second image screen, but the present invention is not limited thereto.
In the present embodiment, the display driver 120 is electrically connected to the e-paper display panel 110 for outputting the driving signal DS to the e-paper display panel 110. In this embodiment, the display driver 120 may be provided with an information generator, and the information generator generates internal information for the display driver 120 to output the driving signal DS to the e-paper display panel 110. In one embodiment, the display driver 120 may also receive external information and provide the output driving signal DS to the e-paper display panel 110 according to the received external information. The present invention does not limit the manner in which the display driver 120 generates and outputs the driving signal DS. Therefore, in the present embodiment, the display driver 120 drives the electronic paper display panel 110 with the driving signal DS to alternately display the first image frame and the second image frame during the information transmission period to transmit the encrypted information.
Specifically, in the present embodiment, the driving signal DS includes the first information level V1 and the second information level V2, as shown in fig. 1, but the present invention is not limited thereto. The display driver 120 drives the electronic paper display panel 110 to display the first image picture by using the driving signal DS of the first information level V1. The display driver 120 drives the electronic paper display panel 110 to display the second image screen by using the driving signal DS at the second information level V2.
In detail, since the electronic paper display panel 110 of the embodiment uses the black display particles and the white display particles as the display medium, when the electronic paper display panel 110 is under the action of the negative field, a white image is displayed, and when the electronic paper display panel 110 is under the action of the positive field, a black image is displayed, therefore, the driving signal DS of the embodiment includes the first information level V1 and the second information level V2, wherein the first information level V1 is higher than the second information level V2, but the invention is not limited thereto. In this way, the display driver 120 can drive the electronic paper display panel 110 to display a first image (i.e., a black image) by using the first information level V1 with a positive electric field, and drive the electronic paper display panel 110 to display a second image (i.e., a white image) by using the second information level V2 with a negative electric field.
In other words, the electronic paper display panel 110 of the present embodiment can display the corresponding image frame according to the driving of the driving signal DS with different information levels. Specifically, referring to fig. 2A and fig. 2B, fig. 2A is a schematic diagram illustrating the electronic paper display panel 110 driven by the driving signal DS to display a first image according to an embodiment of the invention. Fig. 2B is a schematic diagram illustrating the electronic paper display panel 110 driven by the driving signal DS to display a second image according to an embodiment of the invention.
That is, the e-paper display panel 110 can display the corresponding image frames according to the driving of different information levels of the driving signal DS. When the driving signal DS outputted by the display driver 120 has a signal waveform (as the driving signal DS shown in fig. 1) composed of a combination of a series of the first information level V1 and the second information level V2, the electronic paper display panel 110 can alternately display the first image and the second image according to the first information level V1 and the second information level V2 of the driving signal DS. Thus, the electronic paper display device 100 can display the characteristics of the corresponding image frame for transmitting information by the driving of the electronic paper display panel 110 according to different information levels of the driving signal DS.
It should be noted that since the e-paper display panel 110 has a frame switching speed on the order of milliseconds, the frame changing speed is very fast, so that when the e-paper display panel 110 changes different frames to transmit information, the information is difficult to copy and steal. In addition, the display driver 120 of the present embodiment may further output the encoded driving signal DS by encoding the internal information or the received external information. Therefore, in the present embodiment, the driving signal DS contains encrypted information to be transmitted by the electronic paper display panel 110. In this way, during the information transmission period, the combination of the first image frame and the second image frame displayed by the electronic paper display panel 110 includes the encrypted information through the driving of the driving signal DS, so that the electronic paper display apparatus 100 can transmit the encrypted information by alternately displaying the first image frame and the second image frame through the electronic paper display panel 110, thereby greatly improving the security of transmitting the information.
In the encoding process, the display driver 120 may define an encoding method according to various requirements, for example, the internal information or the received external information may be encoded according to the length of time, the frequency, or a specific encoding rule (for example, according to the Morse code rule) to encrypt the information and generate the driving signal DS containing the encrypted information.
In an embodiment, the encoding method adopted by the electronic paper display device 100 is, for example, to define different encoding information according to the frequency. In this example embodiment, the display driver 120 drives the e-paper display panel 110 by using the driving signal DS with the first frequency, so that the e-paper display panel 110 transmits the encoded information in the encrypted information. The display driver 120 drives the electronic paper display panel 110 with the driving signal DS of the second frequency, so that the electronic paper display panel 110 transfers another encoded information of the encrypted information. In this embodiment, the first frequency is not equal to the second frequency.
Fig. 3A is a waveform diagram of a driving signal corresponding to encoded information according to an embodiment of the invention. Referring to fig. 3A, for example, in the present embodiment, the display driver 120 drives the electronic paper display panel 110 by using driving signals DS with different frequencies to encrypt different signals to be transmitted, such as signal 0 and signal 1. In the present embodiment, has a first frequency f1Has a second frequency f and encodes information, for example representing a signal 02Driving signal DS of (1), an example of which encodes informationSuch as representative signal 1. In the present embodiment, the first frequency f1Not equal to the second frequency f2. Thus, during the signal transmission period T1, when the electronic paper display panel 110 is at the first frequency f1Is driven at a first frequency f while switching between a first information level and a second information level1The first image picture and the second image picture are alternately displayed, thereby transferring the signal 0 in the encrypted information. In the present embodiment, during the signal transmission period T2, the electronic paper display panel 110 is at the second frequency f2Is driven at a second frequency f while switching between a first information level and a second information level2The first image picture and the second image picture are alternately displayed, thereby transmitting the signal 1 in the encrypted information. The waveform of the driving signal DS and the corresponding encoded information are illustrated in fig. 3A for illustrative purposes only, and the present invention is not limited thereto. In other embodiments, the electronic paper display device 100 may encrypt the numbers, the english alphabets or other symbols to be transmitted according to different frequencies, which is not limited by the invention.
In another embodiment of the present invention, the display driver 120 drives the electronic paper display panel 110 with a driving signal DS having a plurality of different frequencies, so that the electronic paper display panel 110 delivers one of a plurality of encoded information in the encrypted information. In this exemplary embodiment, the encoded information transmitted by the e-paper display panel 110 is determined according to a combination of different frequencies.
For example, fig. 3B is a waveform diagram illustrating driving information corresponding to encoded information according to another embodiment of the invention. In the present embodiment, the display driver 120 drives the electronic paper display panel 110 with driving signals DS having different frequency combinations to encrypt different information to be transmitted, such as English letters A and B. Referring to fig. 3B, in the present embodiment, during the signal transmission period T3, the frequency of the driving signal DS is changed from the first frequency f1Change to a second frequency f2The combined coded information represents, for example, an english alphabet a. During the signal transmission period T4, the frequency of the driving signal DS is changed from the first frequency f1Change to a second frequency f2Then from the second frequency f2Changing to a first frequency f1The combined coded information represents, for example, an english alphabet B. In the present embodiment, the first frequency f1Likewise not equal to the second frequency f2. Thus, the driving of the e-paper display panel 110 by the driving signal DS can be based on the first frequency f1And a second frequency f2The displayed image is switched in the conversion order to transmit English letters A and B in the encrypted information. The waveform of the driving signal DS and the corresponding encoded information are illustrated in fig. 3B for illustrative purposes only, and the present invention is not limited thereto. In other embodiments, the electronic paper display device 100 may also encrypt the numbers, the english letters, or other symbols to be transmitted according to more combinations of different frequencies, which is not limited by the invention.
In an embodiment of the present invention, the electronic paper display device may first encode the internal information or the received external information to generate a driving signal containing the encrypted information. And then, the electronic paper display panel can display the corresponding image picture according to the driving of different information levels of the driving signal. Therefore, the electronic paper display device can alternately display different image frames during the signal transmission period so as to transmit the encrypted information. Therefore, the confidentiality and the safety of information transmission can be improved.
On the other hand, with the electronic paper display device and the information transmission method thereof, if the transmitted encrypted information needs to be read, the image sensing device can be used to sense the image displayed by the electronic paper display device 100, so as to decode the encrypted information. The following embodiments further illustrate the architecture of an information delivery system with an electronic paper display device.
Fig. 4 is a schematic diagram illustrating an information delivery system according to an embodiment of the present invention. Referring to fig. 4, the information delivery system 400 shown in fig. 4 includes an electronic paper display device 410 and an image sensing device 420. The electronic paper display device 410 and the electronic paper display panel 412 thereof, the display driver 414 and the driving signal DS can be referred to the electronic paper display device 100 and the electronic paper display panel 110 thereof, the display driver 120 and the related description of the driving signal DS shown in fig. 1, and so on, and are not described herein again.
In the embodiment, the image sensing device 420 is configured to receive the encrypted information transmitted by the electronic paper display device 410 and decode the encrypted information to obtain information included in the encrypted information. In the present embodiment, the image sensing device 420 includes an image sensor 422 and a data processor 424. The image sensor 422 may be implemented by an infrared sensing Device, a Charge Coupled Device (CCD), or a Complementary Metal Oxide Semiconductor (CMOS), which is not limited by the invention. The image sensor 422 is used for receiving the encrypted information transmitted by the electronic paper display device 410 and outputting the encrypted information to the data processor 424 at the back end.
In the present embodiment, the data processor 424 is electrically connected to the image sensor 422 for decoding the encrypted information to obtain information included in the encrypted information. The data Processor 424 is, for example, a Central Processing Unit (CPU), or other Programmable general purpose or special purpose Microprocessor (Microprocessor), Digital Signal Processor (DSP), Programmable controller, Application Specific Integrated Circuit (ASIC), Programmable Logic Device (PLD), or other similar devices or combinations thereof, which are not limited by the invention. The following is a detailed description of the steps of the overall information delivery method by way of example.
Fig. 5 is a flow chart illustrating an information delivery method in accordance with an embodiment of the present invention. Referring to fig. 5, the method of the present embodiment is at least suitable for the electronic paper display device 410 and the image sensing device 420 of fig. 4. The following describes the detailed steps of the information transmission method of the present invention with the electronic paper display device 410 and the image sensing device 420.
First, at the transmitting end, the display driver 414 drives the electronic paper display panel 412 of the electronic paper display device 410 to alternately display the first image screen and the second image screen during information transfer, thereby transferring encrypted information in step S510. In this embodiment, the electronic paper display panel 412 uses the black display particles and the white display particles as the display medium similarly to the embodiment of fig. 1, but the invention is not limited thereto. During the signal transmission, the electronic paper display device 410 may alternately display a first image picture composed of, for example, black display particles and a second image picture composed of, for example, white display particles to transmit encrypted information.
At the receiving end, in step S520, the information delivery system 400 receives the encrypted information by the image sensing device 420, and decodes the encrypted information to obtain the information included in the encrypted information. In the present embodiment, the image sensor 422 of the image sensing device 420, for example, transmits a sensing signal to the electronic paper display device 410, and the electronic paper display device 410 feeds back the sensing signal to the image sensor 422, so that the image sensor 422 receives the encrypted information. It is noted that the electronic paper display device 410 displaying the first image absorbs at least part of the sensing signal, and the electronic paper display device 410 displaying the second image reflects at least part of the sensing signal.
Generally, when the infrared sensing device detects an image displayed on the electronic paper display device, a black portion of the image display absorbs infrared rays (sensing signals) emitted by the infrared sensing device, and a white portion of the image display reflects infrared rays (sensing signals) emitted by the infrared sensing device. In the present embodiment, an infrared sensing device is employed as the image sensor 422, for example, but the present invention is not limited thereto. In this example, while the electronic paper display device 410 alternately displays the first image picture composed of black display particles and the second image picture composed of white display particles, infrared rays are emitted to the electronic paper display device 410 through the infrared ray sensing device to dynamically detect the encrypted information transmitted by the electronic paper display device 410. In this way, the electronic paper display device 410 displaying the first image (black) will absorb at least part of the infrared ray, and the electronic paper display device 410 displaying the second image (white) will reflect at least part of the infrared ray, so that the infrared sensing device can sense the encrypted information transmitted by the image displayed by the electronic paper display device 410 according to the feedback sensing signal.
Then, the image sensor 422 receives the encrypted information and then transmits the encrypted information to the data processor 424 for decoding. The data processor 424 can analyze the image frame of the electronic paper display device 410 according to the encrypted information transmitted by the image sensor 422 and the corresponding encoding method (for example, the above-mentioned encoded information with different frequencies or combinations thereof, but the invention is not limited thereto) to obtain the information DD included in the encrypted information. It is worth mentioning that the encrypted information communicated via the information delivery system 400 may also be pre-encrypted using at least one algorithm. The image sensor 422 may decode the encrypted information, for example, with a corresponding back-end processing algorithm, to obtain the information DD included in the encrypted information. Therefore, the encrypted information transmitted through the electronic paper display device 410 is not only difficult to copy and steal, but also can increase the security of information transmission through multiple security measures.
In short, in the information transmission system and the method thereof according to the embodiment of the present invention, the transmission end may transmit the encrypted information by alternately displaying the first image and the second image on the electronic paper display device. And at the receiving end, an infrared sensing device can be adopted to detect the image frames alternately displayed by the electronic paper display device so as to receive the encrypted information. Then, the data processor decodes the encrypted data to obtain the information included in the encrypted information. Therefore, not only the encrypted information transmitted through the electronic paper display device 410 is difficult to copy and steal, but also the security of information transmission can be increased through multiple security measures.
In addition, in other embodiments of the present invention, the e-paper display panel 110, 412 may also transmit the encrypted information through a display manner different from the above-mentioned display manner. For example, the e-paper display panel 412 may further include a plurality of display areas, such that the display driver 414 drives the display areas of the e-paper display panel 410 with the driving signal DS to alternately display the first image frame and the second image frame, so that the e-paper display panel transmits one of the plurality of encoded information in the encrypted information. The encoded information transmitted by the e-paper display panel 410 is determined according to a combination of the first image and the second image displayed in the display area, for example. In addition, the signal transmission method and the panel driving method of the electronic paper display device 410 of the present exemplary embodiment can obtain sufficient teaching, suggestion and implementation description from the description of the embodiments in fig. 1 to fig. 3, and therefore, are not repeated.
Specifically, referring to fig. 6, fig. 6 is a schematic diagram illustrating an electronic paper display panel including a plurality of display areas according to an embodiment of the invention. In the present embodiment, the electronic paper display panel 610 includes display regions a1, a2, A3, a 4. The electronic paper display panel 610 is driven by a driving signal DS to make the display regions a1, a2, A3, and a4 respectively display a first image and a second image. For example, when the display areas a1 and a4 display the first image picture and the display areas a2 and A3 display the second image picture, the combination of the image pictures can correspond to one of a plurality of encoded information, and the encoded information can be defined by the user, as shown in fig. 6, but the invention is not limited thereto. In this way, the electronic paper display panel 610 of the present embodiment can generate a greater variety of encoded information by combining the first image and the second image displayed in each display region. The coded information can be defined by the user, and the image frame can be switched rapidly through the electronic paper display panel 610, thereby improving the security and confidentiality of the transmitted encrypted information. In addition, the signal transmission method and the panel driving method of the electronic paper display panel according to the present exemplary embodiment can obtain sufficient teaching, suggestion and implementation description from the description of the embodiments in fig. 1 to 5, and thus are not repeated.
Fig. 7 is a schematic diagram of an intelligent authentication system according to an embodiment of the present invention. Referring to fig. 7, in the present embodiment, an intelligent authentication system 700 includes an electronic lock 710 and an electronic key 720. The electronic lock 710 includes an electronic lock induction coil 712 and an image sensing device 714. The electronic key 720 includes an induction coil 722 and an electronic paper display 724. An electronic lock induction coil 712 disposed in the electronic lock 710 and an induction coil 722 disposed in the electronic key 720 are used for performing the first-stage authentication operation. An induction coil 722 disposed on the electronic key 720 is coupled to the electronic paper display device 724. The induction coil 722 is used for transmitting the operating power OP to the electronic paper display device 724 during the first-stage authentication so as to enable the electronic paper display device 724 to display the encoded encrypted information. The image sensing device 714 disposed in the electronic lock 710 is during the second stage authentication. The image sensing device 714 receives and decodes the encrypted information displayed by the electronic paper display device 724. The authentication method of the smart authentication system 700 in the present embodiment is described in detail below.
In the present embodiment, during the authentication between the electronic key 720 and the electronic lock 710, the electronic lock induction coil 712 disposed in the electronic lock 710 transmits authentication information to the induction coil 722 of the electronic key 720 for the first-stage authentication. The first-stage authentication may be performed by using Near Field Communication (NFC) or Radio Frequency Identification (RFID) technologies to authenticate the electronic lock 710 and the electronic key 720. If the authentication passes the first stage authentication, the electronic lock induction coil 712 transmits an operating power OP to the induction coil 722 of the electronic key 720, and the operating power OP is used for driving the electronic paper display device 724 disposed on the electronic key 720. On the contrary, if the first-stage authentication is not passed, the electronic lock induction coil 712 does not transmit the operation power OP to the induction coil 722 on the electronic key 720. That is, the electronic lock 710 rejects the first-stage authentication request of the electronic key 720.
In other embodiments, the electronic key 720 may have a battery therein. If the authentication passes the first stage authentication, the electronic lock 710 provides a control signal to the electronic key 720, so that the operation power OP of the battery in the electronic key 720 drives the electronic paper display 724.
In some embodiments, the electronic key 720 may contact a surface of the electronic lock 710. During the period when the electronic key 720 is in contact with the electronic lock 710, the electronic lock induction coil 712 transmits authentication information to the induction coil 722 for identification of the first stage of authentication. In some embodiments, the electronic key 720 may be accessible without contacting a surface of the electronic lock 710. During the period when the electronic key 720 is close to and does not contact the electronic lock 710, the electronic lock induction coil 712 transmits the authentication information to the induction coil 722 for the first stage authentication identification. In some embodiments, the electronic lock 710 has a locking hole, and the electronic lock induction coil 712 is disposed in the locking hole of the electronic lock 710. During the period when the electronic key 720 is inserted into the hole of the electronic lock 710, the electronic lock induction coil 712 transmits the authentication information to the induction coil 722 for the first stage authentication identification.
In some embodiments, if the electronic key 720 fails the first-stage authentication, the electronic lock 710 may provide an alert tone or signal to notify the user holding the electronic key 720 that the first-stage authentication fails.
Referring to fig. 7, in the embodiment, after the electronic paper display device 724 disposed on the electronic key 720 is driven, the electronic paper display device 724 alternately displays a plurality of encoded information combined by the first image frame and the second image frame during the second-stage authentication step so as to transmit the encrypted information ES. The encryption information ES is information set by a user, such as a password or an identification code, and information data generated by encoding and encrypting is generated. In some embodiments, the user may set the information on the electronic lock 710, and then the information is encoded and encrypted by the electronic lock 710. The set information is encoded and encrypted into the encrypted information ES according to the encoding mode selected by the system or the user. Then, the encrypted information ES generated by the electronic lock 710 is transmitted to the electronic key 720 passing the first-stage authentication and the second-stage authentication by using technologies such as near field communication or radio frequency identification. In some embodiments, the electronic key 720 passing through the first-stage authentication and the second-stage authentication may contact the electronic lock 710 to obtain the driving signal containing the encryption information ES. In some embodiments, the electronic key 720 passing the first-stage authentication and the second-stage authentication can access the electronic lock 710 without contacting the electronic lock 710 to obtain the driving signal containing the encryption information ES. In some embodiments, the electronic lock 710 has a locking hole, and the electronic lock induction coil 712 is disposed in the locking hole of the electronic lock 710. During the period that the electronic key 720 is inserted into the keyhole of the electronic lock 710, the electronic key 720 passing through the first-stage authentication and the second-stage authentication can be inserted into the keyhole of the electronic lock 710 to obtain the driving signal containing the encrypted information ES.
In some embodiments, the e-paper display device 724 itself may have an encoding function, and may encode internal information or received external information. That is, the electronic paper display device 724 can encode the information (such as the password or the identification code) received by the electronic key 720 from the user or the information stored in the electronic lock to generate the encrypted information ES, which is not limited by the invention.
In some embodiments, the user may set information, such as a password or an identification code, on a mobile phone, a computer or an information processing interface, and transmit the set information to the electronic lock 710 through wireless transmission, bluetooth, rfid or near field communication. The electronic lock 710 is further transmitted to the electronic key 720 capable of passing the first-stage authentication and the second-stage authentication through the transmission between the electronic lock induction coil 712 and the induction coil 722 by the way of radio frequency identification or near field communication, which is not limited by the invention.
In some embodiments, the e-paper display 724 disposed on the electronic key 720 may increase the complexity of the password or the encoding method according to the resolution of the e-paper display 724 itself, so as to receive the more complex encrypted information ES and display the more complex encoded information combination. In some embodiments, the e-paper display device 724 may further select to use repeated switching of multi-frame coding information during the second stage of authentication, so that the coding information including the encryption information ES is displayed in a dynamic image manner, further increasing the complexity of displaying the encryption information ES. That is, the smart authentication system 700 can increase the complexity of the setting and encoding of the ES encryption information according to the high screen resolution and the high screen switching speed of the e-paper display 724, and further increase the security of the information transmission during the second-stage authentication of the smart authentication system 700.
Referring to fig. 7, in the present embodiment, the image sensing device 714 disposed on the electronic lock 710 includes an image sensor 715 and a data processor 717. The image sensor 715 is used for receiving the encrypted information ES transmitted from the electronic paper display device 724 during the second stage authentication, and outputting the encrypted information ES to the data processor 717. The data processor 717 is used to decode the encrypted information ES from the image sensor 715 during the second stage of authentication to obtain the information, such as the password or the identification code, included in the encrypted information ES before the encoding and encryption. The data processor 717 compares the decoded information with the information stored in the electronic lock 710. If the information decoded by the data processor 717 matches the information stored in the electronic lock 710, which indicates that the electronic key 720 requesting authentication passes the first-stage authentication and the second-stage authentication, the data processor 717 will unlock the electronic lock 710. Otherwise, if the second authentication is not passed, the electronic lock 710 will not be unlocked. That is, the electronic lock 710 rejects the second-stage authentication request of the electronic key 720. In some embodiments, the image sensing device 714 may be disposed in a lock hole of the electronic lock 710 or disposed on a surface of the electronic lock 710 according to an authentication method between the electronic lock 710 and the electronic key 720. But the present invention is not limited thereto. The signal transmission method and the panel driving method of the electronic paper display panel according to the present exemplary embodiment can be obtained from the description of the embodiments in fig. 1 to 6 to obtain sufficient teaching, suggestion and implementation description, and thus are not repeated.
In some embodiments, if the electronic key 720 fails the second-stage authentication, the electronic lock 710 may provide an alert tone or signal to notify the user holding the electronic key 720 that the second-stage authentication fails.
After the electronic key 720 requesting authentication passes the first-stage authentication and the second-stage authentication, the image on the electronic paper display 724 is replaced with a preset reset image according to a preset reset signal inside the smart authentication system. The preset reset signal can also be set by a user, but the invention is not limited thereto.
