[0045] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.
[0046] like Figure 1 As shown, Figure 1 A structural block diagram of an embodiment of an electronic ink screen virtual different display dual-screen control system of the present application is shown. The present application discloses an electronic ink screen virtual different display dual-screen control system, including a main processor, a boost module, a switching module and an electronic ink screen. The main processor is used to output a first control signal, a second control signal and a data signal. The boost module is respectively connected to the main processor, the switching module and the electronic ink screen, and is used to output a constant high-voltage power signal to the electronic ink screen according to the first control signal and to output a VCOM power signal to the switching module. The switching module is respectively connected to the main processor and the electronic ink screen, and is used to receive the data signal and implement the switching of the connection channel according to the second control signal to transmit the VCOM power signal to the first ink screen or the second ink screen. The electronic ink screen is used to display the data content corresponding to the data signal.
[0047] In an embodiment of the present application, the ink screen virtual different display dual screen control system is composed of several main components, including a main processor, a boost module, a switching module and an electronic ink screen, which work together to realize the virtual different display dual screen function. The main processor is the core of the system, responsible for processing and outputting control signals and data signals, and establishing connections with the boost module and the switching module respectively. The boost module is connected to the switching module, and the boost module is implemented using a chip model SYV766ARMC, and outputs a constant high-voltage power supply signal to the electronic ink screen. This high-voltage power supply signal is to drive the ink particles on the ink screen to realize the ink screen display function. The high-voltage power supply signal can be positive high voltage or negative high voltage. When the high-voltage power supply signal takes positive high voltage, its value can be 15V or 27V. When the high-voltage power supply signal takes negative high voltage, its value is -15V or -20V.
[0048] The function of the switching module is to switch the connection channel and receive the VCOM power signal from the main processor. The VCOM power signal is a negative voltage signal with a value of -2V. The signal is transmitted to the first ink screen or the second ink screen as needed. The electronic ink screen includes the first ink screen and the second ink screen, which are used to display the data content corresponding to the data signal. These ink screens are controlled and driven by the main processor, the boost module and the switching module.
[0049] VCOM (Voltage Compensation) is a power supply technology used to drive liquid crystal displays. In liquid crystal displays, VCOM power is used to adjust the bias voltage of the liquid crystal screen to ensure the stability and accuracy of the displayed image. In the ink screen application, the high-voltage power supply output by the boost module is mainly used to drive the ink particles on the ink screen. The ink screen is a technology that uses electric fields to adjust the arrangement of ink particles to display images. When the ink screen needs to display a new image, the high-voltage power supply arranges the ink particles into a specific pattern or text through the action of the electric field.
[0050] The main processor has a built-in ink screen display control unit, which controls the display of the left and right ink screens through a set of switching modules and a boost module. The two ink screens share a high voltage. When the first ink screen needs to change the display, the control switching module connects to the connection channel of the first ink screen, so that the first ink screen can receive the VCOM power signal and data signal, while the connection channel of the second ink screen is disconnected and cannot receive the VCOM power signal and data signal. At this time, the first ink screen responds and processes the data signal to obtain the data to be displayed, and starts to display these data to be displayed on the first ink screen. When the second ink screen needs to change the display, the high-voltage power supply is maintained unchanged, the control switching module connects to the connection channel of the second ink screen, and the connection channel of the first ink screen is cut off at the same time, so that the second ink screen can receive the VCOM power signal and data signal, while the first ink screen cannot receive the VCOM power signal and data signal. At this time, the second ink screen responds and processes the data signal to obtain the data to be displayed, and starts to display these data to be displayed on the second ink screen. When the data display of the first and second ink screens is completed, the boost module is turned off, and the ink screen display control unit stops transmitting the data signal.
[0051] Furthermore, the connection channel includes a VCOM power signal channel and a data signal channel, the VCOM power signal channel and the data signal channel are synchronous communication channels, and the VCOM power signal channel and the data signal channel are synchronously controlled by a switching module. The switching module includes a VCOM control circuit and a data switch, the VCOM control circuit is used to control the connectivity of the VCOM power signal channel, the data switch is used to control the connectivity of the data signal channel, and the data switch is implemented using a chip model SGM44599YTQ16.

Figure 3A VCOM control circuit diagram connected to the second ink screen is shown, and pin VCOM_B is connected to the second ink screen. Among them, the VCOM control circuit connected to the first ink screen includes a first MOS tube Q1, a second MOS tube Q2, a first triode Q3, a first diode D1, a first resistor R1, a second resistor R2 and a third resistor R3, wherein the gate of the first MOS tube Q1 is connected to the VCOM power signal input, the source of the first MOS tube Q1 is grounded, the drain of the first MOS tube Q1 is respectively connected to one end of the first resistor R1 and the second resistor R2, the other end of the first resistor R1 is connected to the power supply VCC of the control circuit, the other end of the second resistor R2 is connected to the base of the first triode Q3, the emitter of the first triode Q3 is connected to the power supply VCC of the control circuit, the collector of the first triode Q3 is connected to the anode of the first diode D1, the cathode of the first diode D1 is connected to the gate of the second MOS tube Q2, one end of the third resistor R3 is connected to the gate of the second MOS tube Q2, the other end of the third resistor R3 is connected to the source of the second MOS tube Q2, and the drain of the second MOS tube Q2 is connected to the first ink screen.
[0053] The VCOM control circuit connected to the second ink screen is similar to the VCOM control circuit connected to the first ink screen, the only difference being that the output end of the control circuit is connected to a different ink screen, and the control circuit specifically includes a third MOS tube Q4, a fourth MOS tube Q5, a second triode Q6, a second diode D2, a fourth resistor R4, a fifth resistor R5 and a sixth resistor R6, wherein the gate of the third MOS tube Q4 is connected to the VCOM power signal input, the source of the third MOS tube Q4 is grounded, and the drain of the third MOS tube Q4 is respectively connected to the fourth resistor R4 and the fifth resistor R5 One end of the fourth resistor R4 is connected to the power supply VCC of the control circuit, the other end of the fifth resistor R5 is connected to the base of the second triode Q6, the emitter of the second triode Q6 is connected to the power supply VCC of the control circuit, the collector of the second triode Q6 is connected to the anode of the second diode D2, the cathode of the second diode D2 is connected to the gate of the fourth MOS tube Q5, one end of the sixth resistor R6 is connected to the gate of the fourth MOS tube Q5, the other end of the sixth resistor R6 is connected to the source of the fourth MOS tube Q5, and the drain of the fourth MOS tube Q5 is connected to the second ink screen.
[0054] Taking the control of the VCOM power signal channel connected to the first ink screen as an example, when the first ink screen needs to display data content, the EINK_A_VCOM_EN terminal obtains the VCOM power signal, and the VCOM power signal is a -2V negative voltage signal. At this time, the first MOS tube Q1 is turned on, and the first MOS tube Q1 outputs a 1.5V low potential, the first transistor Q3 is turned on, and the collector of the first transistor Q3 outputs a 3V potential, the first diode D1 and the second MOS tube Q2 are turned on. At this time, the VCOM power signal channel connected to the first ink screen is connected, and the pin VCOM_A outputs the potential to the first ink screen, thereby realizing the display of the content of the first ink screen.
[0055] When the second ink screen needs to display data content, disconnect the EINK_A_VCOM_EN terminal, and make the EINK_B_VCOM_EN terminal obtain the VCOM power signal, turn on the VCOM power signal channel of the second ink screen, and pin VCOM_B outputs the potential to the second ink screen to display the content of the second ink screen.
[0056] The main processor is provided with an ink screen display control unit, which is used to output data signals to the switching module. The first ink screen and the second ink screen are both 10.3-inch electronic ink screens, and the first ink screen and the second ink screen are connected by FPC connection. FPC connection refers to flexible printed circuit connection (Flexible Printed Circuit connection), also known as FPC connector. FPC connection is a connection method used to connect flexible printed circuits (FPC) and other circuit boards or components in electronic devices.
[0057] In an embodiment of the present application, the VCOM power signal channel includes a first VCOM power signal channel and a second VCOM power signal channel, the first VCOM power signal channel is connected to the first ink screen, the second VCOM power signal channel is connected to the second ink screen, and the switching module can realize the switching of the first VCOM power signal channel and the second VCOM power signal channel to realize the transmission of the VCOM power signal to the first ink screen or the second ink screen.

[0058] It should be additionally explained that the boost module is connected to the electronic ink screen through a high-voltage power supply channel. The high-voltage power supply channel includes a first high-voltage power supply channel and a second high-voltage power supply channel. The first high-voltage power supply channel is connected to the first ink screen, and the second high-voltage power supply channel is connected to the second ink screen. The high-voltage power supply channel is used to transmit a constant high-voltage power supply signal. During the operation of the electronic ink screen, continuously maintaining a constant high-voltage power supply signal can achieve a faster screen refresh speed.
[0059] In general, the main function of the system is to realize the virtual dual-screen display control of the ink screen.

[0063] Please refer to Figure 5 The present application discloses a method for controlling a dual-screen virtual display with an ink screen. The method for controlling a dual-screen virtual display with an ink screen is applied to the control system of the dual-screen virtual display with an ink screen as described above. The method includes:
[0064] S201, outputting a first control signal, and based on the first control signal, controlling the boost module to output a constant high-voltage power signal to the electronic ink screen, and controlling the boost module to output a VCOM power signal;
[0065] S202, outputting a second control signal, and controlling a switching module based on the second control signal to determine a matching connection channel;
[0066] S203, outputting a data signal corresponding to the data content to be displayed, and transmitting a VCOM power signal and a data signal to a target ink screen connected to an end of the matching connection channel, wherein the target ink screen is the first ink screen or the second ink screen;
[0067] S204, displaying data content corresponding to the data signal on the target ink screen based on the VCOM power signal and the data signal.
[0068] In this embodiment, in the control method of virtual different display dual screen of ink screen, first, the main processor outputs a first control signal, and uses the signal to control the boost module to output a constant high-voltage power signal to the ink screen, and this high-voltage power signal is used to drive the ink particles on the ink screen. The main processor outputs a second control signal, and uses the signal to control the switching module. The function of the switching module is to determine the matching connection channel, so that the VCOM power signal and the data signal can be correctly transmitted to the target ink screen where the data content needs to be displayed. Then, the VCOM power signal output by the boost module and the data signal corresponding to the data content to be displayed output by the ink screen display control unit are obtained. These signals are key data for driving the ink screen and displaying the corresponding content. The VCOM power signal and the data signal are transmitted to the target ink screen connected to the end of the matching connection channel. According to the setting of the switching module, the target ink screen can be the first ink screen or the second ink screen. Finally, based on the VCOM power signal and the data signal, the data content corresponding to the data signal is displayed on the target ink screen, and the display effect of virtual different display dual screen is achieved.
[0069] In the above embodiment, the present application controls the display of the left and right ink screens through a group of switching modules and a boost module, determines the matching connection channel through the switching module, and transmits the VCOM power signal output by the boost module and the data signal output by the ink screen display control unit to the target ink screen, thereby realizing the virtual dual-screen display function of the ink screen. Such a system can provide a flexible dual-screen display solution, achieves a faster screen refresh speed under lower operating and sleep power consumption, and is suitable for a variety of application scenarios.
[0070] Further, the step of outputting a second control signal and controlling the switching module based on the second control signal to determine a matching connection channel specifically includes:
[0071] Analyze the second control signal to determine the target ink screen for displaying data content;
[0072] Determine a matching connection channel based on the target ink screen;
[0073] In response to the second control signal, the switching module is controlled to connect the matching connection channel.
[0074] In this embodiment, the second control signal is parsed to determine the target ink screen for displaying data content. The second control signal may contain information about the target ink screen, such as an identifier or indicator. After determining the target ink screen, a matching connection channel is determined based on the information of the target ink screen. The matching connection channel is a channel corresponding to the target ink screen to ensure correct signal transmission and connection. After determining the matching connection channel, according to the content of the second control signal, a corresponding instruction is sent to the switching module to control the connectivity state of the connection channel, so as to ensure that the VCOM power signal and data signal can be transmitted to the correct target ink screen.
[0075] Further, the step of outputting a data signal corresponding to the data content to be displayed, and transmitting the VCOM power signal and the data signal to a target ink screen connected to the end of the matching connection channel specifically includes:
[0076] Get the VCOM power signal from the boost module;
[0077] Obtaining a data signal corresponding to the data content to be displayed from the ink screen display control unit of the main processor;
[0078] The VCOM power signal and data signal are transmitted to the target ink screen through the connected matching connection channel.
[0079] In this embodiment, the VCOM power signal is first obtained from the boost module, and then the data signal corresponding to the data content to be displayed is obtained from the e-ink display control unit of the main processor, and these data signals are usually associated with the content to be displayed on the e-ink screen. Finally, the VCOM power signal and the data signal are transmitted to the target e-ink screen through the connected matching connection channel, and the matching connection channel ensures the correct signal transmission path.
[0080] Furthermore, the step of displaying data content corresponding to the data signal on the target ink screen based on the VCOM power signal and the data signal specifically includes:
[0081] Detecting the VCOM power signal and responding to the VCOM power signal;
[0082] When the VCOM power signal is present and the signal response of the VCOM power signal is completed, the target ink screen is activated;
[0083] Receive data signals, respond to data signals, and display data content corresponding to the data signals on the activated target ink screen.
[0084] In this embodiment, first, the system detects the presence of a VCOM power signal, which is used to adjust the voltage of ink particles in the ink screen to control the display effect. After detecting the VCOM power signal, the system responds to it, which may include performing corresponding voltage adjustment or control operations. Once the response to the VCOM power signal is completed, the system activates the target ink screen. Activating the ink screen means preparing to start the operation of displaying data content. The system then receives data signals, which are usually associated with the content to be displayed on the ink screen. After receiving the data signal, the system responds to it and makes corresponding processing. Finally, based on the VCOM power signal, the response of the data signal, and the activation status of the target ink screen, the system displays the data content corresponding to the data signal on the activated target ink screen. The data content will be rendered and displayed on the ink screen for the user to view.
[0085] Please continue to refer to Figure 1 and Figure 5In this embodiment, the main processor has a built-in ink screen display control unit, which controls the display of the left and right ink screens through a set of switching modules and a boost module, and the two ink screens share a high voltage. When the first ink screen needs to change the display, the control switching module is connected to the connection channel of the first ink screen, so that the first ink screen can receive the VCOM power signal and data signal, while the connection channel of the second ink screen is disconnected, and the VCOM power signal and data signal cannot be received. At this time, the first ink screen responds and processes the data signal to obtain the data to be displayed, and starts to display these data to be displayed on the first ink screen. When the second ink screen needs to change the display, the high-voltage power supply is maintained unchanged, the control switching module is connected to the connection channel of the second ink screen, and the connection channel of the first ink screen is cut off at the same time, so that the second ink screen can receive the VCOM power signal and data signal, while the first ink screen cannot receive the VCOM power signal and data signal. At this time, the second ink screen responds and processes the data signal to obtain the data to be displayed, and starts to display these data to be displayed on the second ink screen. When the data display of the first and second ink screens is completed, the boost module is turned off, and the ink screen display control unit stops transmitting the data signal.
