[Embodiment] The present invention will be further described in detail below with reference to the accompanying drawings. Referring to FIG. 1 , the electronic device 10 includes a liquid crystal display screen 101 , a liquid crystal display control module 102 , an electronic paper display screen 103 , an electronic paper display control module 104 , a main control module 105 , a memory 106 , and a function button 107 . And controlling the switch 108. The electronic paper display screen 103 may be electronic paper based on electrophoresis technology, electronic paper based on electronic powder fluid technology, or the like. In the present embodiment, the electronic paper display screen 103 uses electronic paper based on electrophoresis technology. Moreover, the liquid crystal display screen 101 serves as a main display of the electronic device 10 for displaying a user interface, for example, displaying a navigation interface including a plurality of function icons or displaying contents currently viewed by the user. The electronic paper display 103 serves as an auxiliary display screen for displaying the expanded content of the liquid crystal display screen 101 or displaying the identification content set by the user, for example, displaying the user name, time, and the like. [0009] 099113670 controls a switch 108 for responding to a user operation to control power on and off, and transmitting corresponding control signals (eg, a power off signal and a power on signal) to the main control module 105. The function button 107 is used to perform the function selection form number Α0101, page 5/11, page 0992024090-0, 201137738, and the set operation, for example, the user can select the user interface displayed on the liquid crystal display screen 101 by the function button 107. The corresponding icon activates the corresponding function. [0010] The memory 106 is configured to store preset content that needs to be displayed on the electronic paper display screen 103 in a standby or power-off state of the electronic device, such as a user's name or a user-set travel reminder. [0011] The main control module 105 is configured to detect (corresponding to the previously turned off power signal and the power on signal) control signal sent by the switch 108, when the control signal is a signal to control the power on and off, generate a display command To the electronic paper display control module 104, the electronic paper display control module 104 reads the preset content stored in the memory 106 after receiving the display command, and controls the electronic paper display screen 103 to display the preset content. For example, when the control signal is a signal for controlling the power on and off, the electronic paper display control module 104 reads the user information stored in the memory 106, such as the name, time, or time, and controls the electronic paper display 103 to display. The content. [0012] In another embodiment, after receiving the signal that the control switch 108 is turned off, the main control module 105 first sends a prompt command to the liquid crystal display control module 102, and the liquid crystal display control module 102 receives the prompt command. The rear control liquid crystal display 101 displays a user interface, for example, displaying a prompt interface including "whether or not to display preset content", and the user can select and operate the user interface by operating the function button 107. The main control module 105 determines whether the user selects to display the preset content by detecting the operation of the function button 107. [0013] If the user selects to display the preset content, the main control module 105 sends a display 099113670 Form number Α 0101 Page 6 / 11 pages 0992024090-0 201137738 Ο [0014] [0015] 指令 Command to electronic paper display control mode After receiving the display command, the electronic paper display control module 104 reads the preset content stored in the memory 106 and controls the electronic paper display screen 103 to display the preset content. The main control module 105 controls the power to be turned off after the electronic paper display control module 104 controls the display of the electronic paper display 103. At this time, the liquid crystal display screen 101 and the electronic paper display screen 103 are both in the standby or off state. Since the electronic paper display screen 103 has the feature that the original display content can still be retained on the display screen after the power is turned off, the electronic paper display screen 103 can retain the final display content in the state where the electronic device 10 is in standby or shutdown, thereby implementing the electronic paper. The display screen 103 serves as a function for identifying the display screen. If the user chooses not to display the preset content, the main control module 105 directly controls the power off. At this time, both the liquid crystal display screen 101 and the electronic paper display screen 103 are in a non-display state. In other embodiments, when the liquid crystal display screen 101 is in the no-display state, the main control module 105 can issue a display command to control the electronic paper display control by detecting the internal operation command of the system, such as a trip reminder or sending and receiving mail. The module 104 reads the preset content in the memory and controls the electronic paper display screen 103 to display the preset content, thereby changing the display state and the display content of the electronic paper display screen 103. For example, when the system time reaches the set trip reminding time, the main control module 105 sends a display command to the electronic paper display control module 104, and the electronic paper display control module 104 reads the memory 106 after receiving the display command. The stored preset travel reminder content is controlled and the electronic paper display screen 103 is displayed to display the travel reminder content. The electronic device 10 can realize the dual-display display of the identification display, and the user can display 099113670 form number Α0101, page 7/11, 0992024090-0 [0016] 201137738 when the electronic device 10 is in standby or shutdown. The electronic paper displays the identification content of the screen 103. After the electronic device 10 stands by or is turned off, the electronic paper display screen 103 can display the preset identification content and realize the function of displaying the identification. [0017] It is to be understood that various other changes and modifications can be made in accordance with the technical concept of the present invention, and all such changes and modifications should be protected by the claims of the present invention. range.
