[0051] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art based on this application are within the scope of protection of this application.

[0052] To achieve the integration of wireless communication and display, embodiments of this application provide a display device, see [link to relevant documentation]. Figure 1 The device includes: a wireless communication chip 11, an authentication chip 12, a driver chip 13, and a display substrate 14;

[0053] The wireless communication chip 11 is used to acquire the wireless signal to be authenticated and send the wireless signal to the authentication chip;

[0054] The authentication chip 12 is used to encode the wireless signal to obtain encoded data; match the encoded data with preset permission data to obtain a matching result; generate an authorization display instruction based on the matching result, and send the authorization display instruction to the driver chip.

[0055] The driver chip 13 is used to generate a display rectified waveform signal according to the authorized display instruction, and send the display rectified waveform signal to the display module;

[0056] The display substrate 14 is used to display images according to the display rectified waveform signal.

[0057] The wireless communication chip connects to the antenna in the display device. This antenna can be an NFC antenna or an RFID antenna, etc., and the specific configuration can be determined based on the actual frequency band requirements. When interfacing with external signal devices, the wireless communication chip acquires the wireless signal to be authenticated sent by the external signal device through the antenna and then sends the wireless signal to the authentication chip.

[0058] The authentication chip encodes the wireless signal, which means converting the wireless signal into a format that the authentication chip and driver chip can recognize, resulting in encoded data. This encoded data is then matched against preset permission data to obtain a matching result. The preset permission data can be data already acquired by the authentication chip before the matching step. For example, the preset permission data could be a key pre-stored in the display device, a key obtained by the device through the network, or a key entered by the user in real time. The preset permission data is used to match the encoded data to obtain a matching result. For example, the encoded fingerprint information is matched against pre-stored fingerprint data to obtain a matching result. Based on the matching result, an authorization display command is generated and sent to the driver chip.

[0059] The driver chip, based on the received authorized display instruction, rectifies and modulates the information to be displayed into the waveform required for display, generates a display rectified waveform signal, and sends the display rectified waveform signal to the display module. The display substrate then displays the image according to the display rectified waveform signal.

[0060] In this embodiment, a wireless communication chip, an authentication chip, a driver chip, and a display substrate are used to authenticate the wireless signal before displaying the image through the display module, thus combining wireless communication with display. The display device provided in this embodiment can be integrated with the Internet of Things and applied in many applications, primarily in the field of public anti-counterfeiting, such as for credit cards, famous paintings, or personal luxury goods.

[0061] In one possible implementation, the wireless communication chip is specifically used to: upon receiving a wireless signal, perform frequency detection on the wireless signal; and if the signal frequency of the wireless signal is a preset signal frequency, send the wireless signal to the authentication chip.

[0062] The preset signal frequency can be customized according to the actual communication agreement. For example, it can be 13.56MHz for the NFC band or 800 / 900MHz for the RFID band.

[0063] When the wireless communication chip interfaces with an external signal device, it starts up and performs frequency detection on the wireless signal. If the signal frequency of the wireless signal is the preset signal frequency (i.e., frequency matching), the wireless signal is identified as the wireless signal to be authenticated and sent to the authentication chip. If the signal frequency of the wireless signal is not the preset signal frequency (i.e., frequency mismatch), the handshake process is terminated.

[0064] In this embodiment of the application, the wireless signal is frequency detected by the wireless communication chip. Based on whether the signal frequency of the wireless signal is a preset signal frequency, the wireless signal to be authenticated is determined and sent to the authentication chip, which can filter out the wireless signal to be authenticated.

[0065] In one possible implementation, the wireless signal includes an authentication signal and a display signal; the authentication chip is specifically used to: encode the wireless signal to generate authentication data encoded from the authentication signal and display data encoded from the display signal; match the authentication data with preset permission data to obtain a matching result; if the matching result indicates a match, generate an authorization display instruction based on the display data and send the authorization display instruction to the driver chip.

[0066] The wireless signal includes a signal to be authenticated and a signal to be displayed. The authentication chip encodes the wireless signal to generate authentication data obtained from the authentication signal and display data obtained from the display signal. The authentication data is used to verify validity. The authentication data is matched with preset permission data to obtain a valid matching result. If a match is found, authorization is obtained. An authorization display command is generated based on the display data and sent to the driver chip.

[0067] The signal to be displayed is the information that the user needs to display, such as securities information, personal identification information, personal property information, etc.

[0068] In this embodiment, the authentication chip can encode the wireless signal to be authenticated, and at the same time verify the validity of authorization. Based on the verification result, the data to be displayed is authorized, an authorization display instruction is generated, and the authorization display instruction is sent to the driver chip.

[0069] In one possible implementation, the authentication chip is specifically used to: when the matching result indicates a match, encode the data to be displayed, and add the encoded data to be displayed to a message of a preset format to obtain an authorized display instruction.

[0070] The preset message format can be any existing message format, such as an ARP message or a PING message. This application does not limit the specific format of the message. A message typically includes a header and a body. The header includes information such as the destination address and source address, and the body includes the data to be transmitted. In this application, the encoded data to be displayed is added to the body of the preset message format.

[0071] In this embodiment of the application, when the matching result indicates a match, the data to be displayed is encoded, and the encoded data to be displayed is added to a message in a preset format to obtain an authorized display instruction.

[0072] In one example, see Figure 2 The diagram shows the workflow of each component in the display device of this application.

[0073] In one possible implementation, the display substrate is provided with a coil, a fingerprint submodule, and a pixel array; the authentication chip is a fingerprint authentication chip.

[0074] The display substrate is also used to receive wireless signals sent by an external device based on the coil, and send the wireless signals to the wireless communication chip; based on the fingerprint submodule, it acquires user fingerprint data input by the user, and sends the fingerprint data to the fingerprint authentication chip;

[0075] The display substrate is specifically used to display an image using the pixel array according to the display rectified waveform signal;

[0076] The fingerprint authentication chip is specifically used to match the data to be authenticated with the user's fingerprint data to obtain a matching result.

[0077] In one example, to save space, the antenna can be built into the display substrate. In this embodiment, the coil in the display substrate serves as the antenna to which the wireless communication chip is connected. Furthermore, the coil can also function as a power supply line. See also... Figure 3This is a schematic diagram of a display substrate. Two sets of coils are set in the figure. The two sets of coils are electromagnetic induction coils. The two sets of coils are represented by black and gray lines in the figure.

The smallest recognition unit PPI (density unit) it contains is 300 or higher. In one example, the density of the smallest recognition unit PPI can be 400.
