[0002] In digital office and smart meeting scenarios, double-sided display nameplates, with their ability to simultaneously display different information, have become an important medium for efficient information transmission. Existing double-sided display nameplates generally support basic functions such as refreshing both sides or refreshing only one side. Users need to pre-edit the display image, manually select the display side (front, back, or both sides) and then execute the refresh command to update the content. However, this workflow has significant limitations. For example, the current system lacks a robust status feedback mechanism. When abnormal situations such as incomplete refresh or unexecuted commands occur, the update status cannot be promptly notified to the user, making it impossible for the user to determine whether the information is accurately presented or to quickly respond to and re-execute commands.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0014] It should also be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the invention. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0015] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0016] Please see below. Figure 1 The present invention provides an electronic table card control method, which is applied to a host computer connected to an electronic table card. The method includes steps S101 to S102.

[0017] Step S101: Send target data to the electronic table sign, the target data being used to update the content of the electronic table sign; Step S102: Obtain update feedback from the electronic table sign. If the update feedback does not meet the threshold, resend the target data to the electronic table sign.

[0018] In this embodiment, when updating the content of the electronic table sign, the target data to be updated is first obtained and sent to the electronic table sign. Then, the update feedback sent by the electronic table sign is obtained. If the update feedback does not meet the threshold, the target data is resent to the electronic table sign. This can optimize the refresh method of the electronic table sign, improve the update efficiency of the electronic table sign, reduce the refresh time, and avoid the occurrence of the abnormal phenomenon of not being refreshed, thereby achieving a more suitable interactive requirement.

[0019] It should be noted that the refresh of the electronic table card is achieved by issuing commands through a host computer software system. Existing common refresh methods, in order to achieve a better display effect, often employ a full-screen refresh with alternating black and white flickering. However, this method is time-consuming and unsuitable for interactive table cards. This embodiment optimizes the refresh method by directly refreshing the changed parts of the screen when content needs updating, while leaving the unchanged parts static – a partial direct refresh. This eliminates the need for the alternating black and white flickering full-screen refresh, performing only a single direct refresh operation. This saves time by accelerating screen updates and improving the efficiency of the electronic table card's update.

[0020] The step of obtaining update feedback for the electronic table sign, and resending the target data to the electronic table sign if the update feedback does not meet a threshold, includes: The update status of the electronic table card is obtained based on the update feedback; When the update status of the electronic table sign is incomplete, it is determined that the update feedback does not meet the threshold, and the target data continues to be sent to the electronic table sign to enable the electronic table sign to continue updating its content until the update status of the electronic table sign is complete. At this point, it is determined that the update feedback has reached the update threshold.

[0021] In this embodiment, after receiving the update feedback from the electronic table sign, if the update status shows that it is not completed, the target data is continuously sent to keep the electronic table sign updating until the update is completed. This can optimize the refresh method of the electronic table sign, improve the update efficiency, reduce the refresh time, and avoid the abnormal phenomenon of not refreshing, thereby achieving a more suitable interactive requirement.

[0022] In one embodiment, obtaining the update status of the electronic table card based on the update feedback includes: When the time of receiving the update feedback is within a preset time threshold, the update feedback is parsed to determine whether the electronic table card has been updated. If it is determined that the electronic table sign has been updated, then the update status of the electronic table sign is set to complete update; If it is determined that the electronic table card update is incomplete, then the update status of the electronic table card is set to incomplete update.

[0023] In addition, the electronic nameplate control method also includes: If the update feedback is not received within the preset time threshold, the update status of the electronic table card is set to incomplete.

[0024] In this embodiment, when determining the update status of the electronic table sign, a preset time threshold is used as a node: if update feedback is received within the threshold, the feedback is parsed, and the update status is determined based on the parsing result. If the update is fully completed, the update status is set to "complete update"; if only a partial update is completed, it is set to "incomplete update". If no update feedback is received within the preset time threshold, the update status of the electronic table sign is also set to "incomplete update". For example, if the preset time threshold is 3 seconds, if no update feedback is received within 3 seconds, it is determined to be "incomplete update". If update feedback is received within 3 seconds, the feedback is further parsed to determine whether the update is fully or partially completed, thereby setting the update status of the electronic table sign.

[0025] In practical applications, if the electronic table sign is not updated, it will not send update feedback to the host computer. If the update is incomplete, it will send feedback data "0" to the host computer. If the update is complete, it will send feedback data "1" to the host computer. In this way, the host computer can determine the update status of the electronic table sign based on the feedback information.

[0026] Furthermore, in a specific embodiment, the host computer can set up a listening event function to receive feedback messages from the electronic table card. For example, during the listening process, the host computer system compares the received feedback data with a preset update completion standard. Once a "1" is detected, it indicates that the electronic table card has been successfully updated; if a "0" is received, it indicates that the update has not yet been fully completed.

[0027] In one embodiment, when the update status of the electronic table sign is incomplete, it is determined that the update feedback does not meet the threshold, and target data continues to be sent to the electronic table sign to enable it to continue updating its content until the update status of the electronic table sign is complete. At this point, determining that the update feedback has reached the update threshold includes: When the incomplete update is due to the electronic table card not being fully updated, waveform compensation is performed on the target data, and the waveform-compensated target data is sent to the electronic table card. When the incomplete update means that no update feedback has been received within a preset time threshold, the target data is directly sent to the electronic table card again.

[0028] In this embodiment, when the electronic table sign is in an incomplete update state, if the incomplete update is set due to the lack of update feedback, the target data can be sent to the electronic table sign again, so that the electronic table sign can perform the update operation again.

[0029] Specifically, when the incomplete update is due to an incomplete update of the electronic table sign, waveform compensation is performed on the target data, and the waveform-compensated target data is sent to the electronic table sign, including: Extract the original waveform data corresponding to the target data; The original waveform data is set as compensated waveform data with a shorter duration or fewer repetitions. Here, if the incomplete update is due to an incomplete update, it means the current waveform is insufficient to drive the screen to be updated. Therefore, this embodiment uses a compensation waveform with a shorter duration or fewer repetitions to re-drive the relevant content, enabling the electronic table card to complete the update. This avoids the phenomenon of the electronic table card not refreshing or having a poor refresh effect. Furthermore, if the electronic table card still does not update or the update is incomplete after multiple update operations, the system will report an error to remind the user to promptly identify the problem and take corresponding solutions.

[0030] In practical applications, the content and update method of the electronic nameplate can be updated according to the user's instructions. For example, the software system of the host computer can add previous / next / single-sided / double-sided control buttons, which can realize the switching of the previous or next screen, as well as the selection of single-screen refresh or dual-screen refresh.

[0031] In one embodiment, sending the target data to the electronic nameplate includes: The Bluetooth protocol is used to simulate SPI serial communication, and the target data is sent to the electronic table card based on the Bluetooth protocol.

[0032] This embodiment uses Bluetooth protocol to simulate SPI serial communication to achieve bidirectional data transmission, enabling the host computer's software system to quickly interact with the electronic nameplate. After receiving information, the electronic nameplate processes it and executes relevant operations according to the instructions to update the screen. After the update is complete, it feeds back the corresponding message to the software system. The software system receives the message, processes it, and continues to perform the next instruction operation, feeding back the corresponding message to the host computer. This speeds up the response and better meets the real-time interaction requirements of the nameplate.

[0033] Figure 2 This is another flowchart illustrating an electronic table card control method provided in an embodiment of the present invention. The method is applied to electronic table cards and includes steps S201 to S204.

[0034] Step S201: Receive the target data to be updated sent by the host computer; Step S202: Obtain the difference data between the current data and the target data, and set the difference data as the changed pixel point; Step S203: Based on the target data, perform local direct refresh on the changed pixels in the current data; Step S204: Return update feedback to the host computer based on the update result.

[0035] In this embodiment, when the electronic table sign receives target data sent by the host computer, it updates the target data using a partial direct-push refresh method and sends update feedback to the host computer after the update. For example, the electronic table sign can send update feedback indicating a complete update or a partial update based on the actual update situation. Of course, if the electronic table sign has not been updated, no update feedback is sent to the host computer. Here, this embodiment optimizes the screen refresh method to a partial change direct-push refresh, which can speed up the content update speed and thus better realize the interaction effect between the host computer and the electronic table sign. Specifically, firstly, the difference data between the current data and the target data is obtained, and the difference data is set as the changed pixel point; then, based on the target data, a partial direct-push refresh is performed on the changed pixel point on the current data.

[0036] It should be noted that, because the driver chip used in current electronic nameplates can perform image comparison—that is, compare the image corresponding to the current data with the image corresponding to the target data—it can obtain the distinguishing pixel points between the current data and the target data. These distinguishing pixel points are then used as change data points to refresh the current data using the target data, ensuring that the distinguishing pixel points of the current data are updated to match those of the target data. Furthermore, the direct-drive method used in this embodiment means that during e-ink screen particle driving, the black and white particles are driven only once. This avoids the flickering phenomenon caused by the black and white particles moving up and down, thereby improving the refresh effect.

[0037] It should also be noted that direct push refers to the process where an e-ink screen moves black and white particles when displaying content; pushing up black particles displays black, and pushing up white particles displays white. Generally, for better display quality, the screen moves up and down several times to ensure the black and white particles are repeatedly separated and do not overlap, but this requires more time. The direct push described in this embodiment, however, only requires one push to display the image, and it consumes less time, thereby improving the refresh efficiency of the electronic nameplate.

[0038] In practical applications, combining the fast speed of local direct refresh with the interactive functionality between the host computer and the electronic nameplate can better meet the real-time interaction needs of the electronic nameplate. For example, during a meeting, if a speaker forgets their words, the host computer can send a prompt message to the electronic nameplate in real time, and the electronic nameplate can quickly update and display the prompt message through local direct refresh.
