[0045] First, the terms involved in the present application are analyzed:
[0046] Electronic ink screen technology: also known as ink screen technology, is a screen technology using electronic ink, which is currently mainly applied to devices such as readers. Among them, the ink screen display content does not need to consume power, and the ink screen needs to consume power when changing content, so the ink screen can display the picture under the condition of turning off the power supply.

[0049] Figure 1 is an optional module block diagram of a learning machine circuit provided by the embodiments of the present application. Figure 1 The learning machine circuit in can include but is not limited to including:
[0050] a power control module 100, a display driving module 200, an ink screen 300, and a signal detection module 400;
[0051] The power control module 100 is electrically connected to the signal detection module 400 and the display driving module 200; the display driving module 200 is electrically connected to the ink screen 300;
[0052] The ink screen 300 is used to display information; the display driving module 200 is used to control the refresh frequency of the ink screen 300;
[0053] The signal detection module 400 is used to obtain an external signal; the display driving module 200 is further used to control the ink screen 300 to perform full-screen refresh according to the voltage output by the power control module 100 in response to the external signal.
[0054] The beneficial effects of the embodiments of the present application include but are not limited to: displaying text, images, and other information through the ink screen 300, and controlling the refresh frequency of the ink screen 300 through the display driving module 200, so as to control the ink screen 300 to update the display information at a suitable frequency. In addition, in the case where the signal detection module 400 obtains an external signal, the display driving module 200 controls the ink screen 300 to perform full-screen refresh according to the voltage output by the power control module 100 in response to the external signal, thereby reducing the possibility of abnormal phenomena such as residual image, vertical line, etc. when displaying information, preventing residual image of the ink screen 300, and improving the display quality of the learning machine.
[0055] In some embodiments, the information displayed by the ink screen 300 can include text, images, and the like. For example, in the scenario of electronic education, the electronic learning machine circuit of the embodiments of the present application can be applied to a learning machine, such as a word learning machine. In the word learning machine, the ink screen 300 can be used to display words and images corresponding to the words. It should be noted that the word learning machine, as a learning aid, is widely used in the education scenarios of preschool and school-age.
[0056] Specifically, the screen size of the ink screen 300 includes 2.4 inches, and can also be other sizes, without being limited thereto.
[0057] In some embodiments, it should be noted that the current word learning machine usually uses an LCD screen, which is easy to damage the user's vision, especially in the case of long-time reading and learning. The embodiments of the present application adopt the ink screen 300, so that the display effect of the learning machine screen is close to that of a paper book, effectively reduces blue light radiation, is not easy to cause visual fatigue, is suitable for the case of long-time use of the learning machine, and can provide a comfortable reading and learning experience for the user.
[0058] It should be noted that the power control module 100 is a module for power supply. The display driving module 200 is a module for driving the ink screen 300. In some embodiments, the power control module 100 can include a microcontroller (Microcontroller Unit, MCU). In another embodiment, the power control module 100 can also include a voltage conversion unit, such as a DC-DC converter. The voltage conversion unit is electrically connected to the microcontroller and is used for voltage conversion. For example, the voltage conversion unit of the power control module 100 can be powered by a 3.7-volt (V) lithium battery, so that the voltage conversion unit converts the input voltage of the lithium battery to an output voltage, such as 40V.
[0059] In another embodiment, the power control module 100 further includes a thermistor; one end of the thermistor is electrically connected to the microcontroller and the display driving module 200, and the other end is grounded. The thermistor is used to disconnect in the case that the current of the microcontroller is too large (such as greater than a preset current threshold), so as to perform overcurrent protection.
[0060] In some embodiments, the current ink screen is prone to abnormal display, especially during the process of switching the screen, and is prone to residual image. It should be noted that the main reasons for the residual image of the ink screen include that the particles in part of the ink capsules in the ink screen are disturbed by the electric field, causing the ink screen to fail to display correctly, thereby causing abnormal phenomena such as residual image, vertical line, horizontal line, and diagonal line. Especially when the display content of the ink screen is updated locally during the process of switching the screen, this influence is particularly obvious. In view of the problem that the ink screen is difficult to display normally and stably, the display driving module 200 is used to control the ink screen 300 to perform dynamic refreshing, and when an external signal is detected, the display driving module 200 is used to control the ink screen 300 to perform full-screen refreshing according to the voltage output by the power control module 100, so as to avoid the residual image of the ink screen 300 as much as possible and improve the display quality of the learning machine.
[0061] In some embodiments, the display driving module 200 sends an SPI (Serial Peripheral Interface) signal to the ink screen 300, and adjusts the frequency of the SPI signal to control the refreshing frequency of the ink screen 300, thereby dynamically refreshing the ink screen 300.
[0062] It should be noted that the signal detection module 400 is a module for detecting an external signal. In some embodiments, the signal detection module 400 can include a key unit, and the signal detected by the key unit is a key signal. The display driving module 200 controls the ink screen 300 to perform full-screen refreshing according to the voltage output by the power control module 100 in response to the key unit detecting a preset number of external signals within a preset time range. For example, when the key unit detects 10 key signals within 1 minute, the display driving module 200 controls the ink screen 300 to perform full-screen refreshing according to the voltage output by the power control module 100.
[0063] In some embodiments, it should be noted that the display content of the current learning machine is relatively fixed and cannot be adjusted according to the needs of the user or the age of the user. For example, after obtaining the age of the user, the learning machine can perform word searching on a pre-created word learning content library according to the age and voice of the user to obtain a word, so as to play the audio corresponding to the word. The content in the word learning content library is classified according to age.
[0064] Please refer to Figure 2 In some embodiments, the learning machine circuit can further include, but is not limited to, a backlight module 500.
[0065] The backlight module 500 is electrically connected to the display driving module 200.
[0066] The power control module 100 is configured to control the display driving module 200 to adjust the brightness of the backlight module 500; and the backlight module 500 is configured to illuminate the ink screen 300.
[0067] The advantage of this embodiment is that, by the power control module 100, the display driving module 200 is controlled to adjust the brightness of the backlight module 500, so that the backlight module 500 illuminates the ink screen 300, and the information displayed on the ink screen 300 can be clearly visible in a dim environment, further improving the display quality of the ink screen 300.
[0068] It should be noted that the backlight module 500 is a module for illuminating the ink screen 300. In some embodiments, the backlight module 500 is arranged opposite to one side (such as the back) of the ink screen 300.
[0069] In some embodiments, the display driving module 200 sends a PWM (Pulse Width Modulation) signal to the backlight module 500, and by adjusting the frequency of the PWM signal, the brightness of the backlight module 500 is controlled, and then the ink screen 300 is illuminated, realizing real-time adjustment of the brightness of the ink screen 300.
[0070] Please refer to Figure 2 In some embodiments, the backlight module 500 is electrically connected to the ink screen 300.
[0071] The backlight module 500 is configured to adjust the brightness according to the feedback signal of the ink screen 300.
[0072] The advantage of this embodiment is that, by the backlight module 500 connected to the ink screen 300, the feedback signal of the ink screen 300 is obtained, and then the brightness is adjusted according to the feedback signal of the ink screen 300, so that the brightness of the backlight module 500 is accurately controlled according to the feedback signal, realizing real-time adjustment of the brightness of the ink screen 300 and improving the display quality of the learning machine.
[0073] In some embodiments, the ink screen 300 is configured to send the feedback signal to the backlight module 500. The feedback signal can include a synchronization signal. For example, the backlight module 500 adjusts the brightness in response to the synchronization signal, so that the brightness of the backlight module 500 can be more accurately controlled based on the feedback of the ink screen 300.
[0074] Please refer to Figure 3 In some embodiments, the backlight module 500 includes a MOS tube Q1, an inductor L1, a first diode D1, a second diode D2, a third diode D3, a first capacitor C1, a second capacitor C2, a third capacitor C3, and a fourth capacitor C4.
[0075] The gate of the MOS tube Q1 is electrically connected with the ink screen 300; the source of the MOS tube Q1 is grounded; and the drain of the MOS tube Q1 is electrically connected with one end of the inductor L1, one end of the second capacitor C2, and the input end of the third diode D3.
[0076] The other end of the inductor L1 is electrically connected with the display driving module 200 and one end of the first capacitor C1, and the other end of the first capacitor C1 is grounded; the other end of the second capacitor C2 is electrically connected with the output end of the first diode D1 and the input end of the second diode D2; the input end of the first diode D1 is electrically connected with one end of the third capacitor C3, and the other end of the third capacitor C3 is grounded; the output end of the second diode D2 is grounded; and the output end of the third diode D3 is electrically connected with one end of the fourth capacitor C4, and the other end of the fourth capacitor C4 is grounded.
[0077] The embodiment has the advantage that the brightness is adjusted by the backlight module 500 composed of the MOS tube Q1, the inductor L1, the first diode D1, the second diode D2, the third diode D3, the first capacitor C1, the second capacitor C2, the third capacitor C3, and the fourth capacitor C4, so as to illuminate the ink screen 300, and the information displayed by the ink screen 300 can be clearly visible in a dim environment, and the display quality of the ink screen 300 is further improved.
[0078] It should be noted that, in the Figure 3 , the GDR interface is used to connect the electronic screen, and the VCC_EPD interface is used to connect the display driving module 200. DGND represents digital ground.
[0079] In some embodiments, the backlight module 500 further includes a serial interface unit. Specifically, the serial interface unit can be a serial peripheral interface (Serial Peripheral Interface, SPI).
[0080] Please refer to Figure 4 , in some embodiments, the learning machine circuit further includes a clock module 600;
[0081] The clock module 600 is electrically connected with the power supply control module 100;
[0082] The clock module 600 is used for timing;
[0083] The power supply control module 100 is used for controlling the display driving module 200 to be closed and the clock module 600 to be opened in response to a standby instruction; and the power supply control module 100 is further used for controlling the display driving module 200 to be opened in response to the timing of the clock module 600 being ended.
[0084] The embodiment has the advantages that, in response to the standby instruction, the power control module 100 controls the display driving module 200 to be closed, so as to close unnecessary hardware modules and reduce power consumption. In addition, the power control module 100 controls the clock module 600 with low power consumption to be opened, so that the clock module 600 can continue to count in the standby state. When the clock module 600 finishes counting, the power control module 100 controls the display driving module 200 to be opened in response to the clock module 600 finishing counting, so as to end the standby state. It can be seen that the embodiment can reduce the power consumption of the learning machine circuit, thereby prolonging the use time of the learning machine and reducing the need for frequent charging.
[0085] In some embodiments, the clock module 600 can include any one or more of an external crystal oscillator (XTAL) and a real-time clock (RTC). It should be noted that the external crystal oscillator, also known as an external crystal (XTAL), is an electronic component that uses the piezoelectric effect of a quartz crystal to generate a high-precision oscillation frequency, and is commonly used to provide a stable clock signal. The clock chip is a clock source that can continue to operate when the main power supply is powered off.
[0086] In some embodiments, the clock module 600 can also be used for timing the on-off. For example, a 6-hour on time can be set at 10:00, and the clock module 600 starts counting from 10:00 for 6 hours. In addition, assuming that the learning machine is in a standby state during the counting process, unnecessary modules are automatically closed to reduce power consumption, and only the lowest power consumption module, such as the clock module 600, is retained. When 16:00 is reached, the clock module 600 finishes counting, and the power control module 100 controls the display driving module 200 to be opened in response to the clock module 600 finishing counting, so as to end the standby state, and the refresh of the ink screen 300 can be controlled through the display driving module 200, thereby realizing the timing of the learning machine. In addition, the embodiment can also reduce power consumption, for example, the learning machine can be used for a long time, such as 15 days, after being fully charged. For another example, assuming that the learning machine is not used after being fully charged, it can be in standby for more than 3 months, thereby solving the problem of the battery of the learning machine not being durable, allowing the user to use the learning machine at any time and anywhere without the need to frequently find charging equipment, thereby improving the use convenience of the learning machine.
[0087] In some embodiments, the signal detection module 400 includes a key unit (not shown in the figure);
[0088] The key unit is electrically connected to the power control module 100;
[0089] The power control module 100 is configured to control the display driving module 200 to be turned off and the key unit to be turned on in response to the standby instruction.
[0090] The power control module 100 is configured to control the display driving module 200 to be turned off in response to the standby instruction, i.e., when the learning machine is in the standby state, so as to turn off unnecessary hardware modules and reduce power consumption. In addition, the key unit is turned on so that the key unit can receive external signals in the standby state. When the key unit detects the trigger signal, the power control module 100 is further configured to control the display driving module 200 to be turned on in response to the key unit detecting the trigger signal, so as to end the standby state. It can be seen that the embodiment of the present application can reduce the power consumption of the learning machine circuit and prolong the use time of the learning machine without frequent charging.
[0091] In some embodiments, the learning machine circuit can further include a wireless communication module. Specifically, the wireless communication module can include a Bluetooth unit, a WI FI unit, an antenna, etc. Through the wireless communication unit, the external device can be connected in communication, so as to obtain information such as images, audio, instructions, etc. sent by the external device. The external device can include a mobile terminal such as a mobile phone. In the standby state, the power control module 100 can control the wireless communication module to be turned off, so as to further reduce the power consumption.
[0092] In some embodiments, the power control module 100 includes a microcontroller and a direct current converter (not shown in the figure);
[0093] The microcontroller is electrically connected to the direct current converter, the signal detection module 400, and the display driving module 200.
[0094] The power consumption of the microcontroller includes 1 microampere to 8 microamperes.
[0095] The power consumption of the microcontroller includes 1 microampere to 8 microamperes.
[0096] In some embodiments, specifically, the power consumption of the microcontroller can be any one of 1, 2, 4, 6, and 8 microamperes. For example, the static power consumption of the microcontroller can be 4 microamperes, so as to reduce energy loss.
[0097] Please refer to Figure 5 In some embodiments, the learning machine circuit further includes an audio output module 700.
[0098] The audio output module 700 is electrically connected with a microcontroller (not shown in the figure). The microcontroller is configured to control the audio output module 700 to output the voice signal.
[0099] The embodiment has the advantage that the microcontroller controls the audio output module 700 to output the voice signal, so that the voice signal can be played through the audio output module 700, and the interaction diversity between the learning machine and the user is improved.
[0100] In some embodiments, the audio output module 700 refers to a module for playing audio. Specifically, the audio output module 700 can include a loudspeaker. In another embodiment, the audio output module 700 can also include other devices such as a speaker, without being limited thereto.
[0101] It should be noted that the audio played by the audio output module 700 can include voice. For example, for a word learning machine, the audio output module 700 can be used to play voice such as word content.
[0102] In another embodiment, the learning machine circuit further includes an audio input module such as an earphone module, a microphone module, etc.
[0103] Please refer to Figure 6 In some embodiments, the learning machine circuit further includes an image enhancement module 800.
[0104] The image enhancement module 800 is electrically connected with the power control module 100 and the ink screen 300.
[0105] The image enhancement module 800 is configured to perform image enhancement processing on the display content of the ink screen 300.
[0106] The embodiment has the advantage that the image enhancement module 800 performs image enhancement processing on the display content of the ink screen 300, so that the display quality of the learning machine is further improved.
[0107] In some embodiments, the image enhancement module 800 can perform image enhancement processing on the display content of the ink screen 300 through an image rendering algorithm. For example, the image enhancement processing can include one or more of grayscale optimization and edge enhancement processing. Through grayscale optimization and edge enhancement processing, the screen display effect of the learning machine can be highly close to a real paper book, and the reading and learning experience of the user is improved.
