Description

Technical Field

[0001] This application relates to the field of computer technology, and in particular, to a display method and an electronic device. Background Art

[0002] Currently, after an electronic device receives a user's power-on operation, it can start up and display an icon on the display screen to prompt the user that the electronic device has started up. However, it takes 3 seconds or even longer for the electronic device to display the icon on the display screen after receiving the power-on operation. During this period, it is difficult for the user to perceive whether the electronic device has started up, resulting in the user may perform ineffective power-on operations such as pressing the power button again, and the user experience is poor. Summary of the Invention

[0003] This application discloses a display method and an electronic device, which can reduce the delay of displaying the icon after power-on, reduce the waiting time and anxiety of the user, timely remind the user of the power-on state of the electronic device, avoid redundant operations of the user to power on again, and improve the user experience.

[0004] In a first aspect, an embodiment of this application provides an electronic device, including a power-on detection unit, a main chip, a first control unit, and a display module. The display module includes a display power supply, a display driver chip, and a display panel. Among them, the first control unit is configured to initialize when receiving a first signal sent by the power-on detection unit, and the first signal is used to indicate that the electronic device starts up; the main chip is configured to initialize when receiving a second signal sent by the power-on detection unit or the first control unit; the first control unit is configured to send a third signal to the display power supply when the initialization is completed, and the third signal is used to enable the display power supply; the first control unit is configured to send a fourth signal to the display driver chip when the initialization is completed, and the fourth signal is used to trigger the display panel to display a first icon, and the first icon is an icon stored in the display module.

[0005] In the above electronic device, the electronic device adds a first control unit, so that the electronic device does not need to wait for the main chip to complete the initialization before displaying the icon after receiving the first signal, but before the main chip completes the initialization (after the first control unit completes the initialization), the display module can be powered on and initialized by the first control unit, so as to display the first icon. The electronic device decouples the initialization of the display module and the main chip. The independent initialization time of the first control unit is shorter, thereby reducing the delay of displaying the icon after power-on, reducing the waiting time and anxiety of the user, avoiding redundant operations of the user to power on again, and improving the user experience.

[0006] In a possible implementation, the first duration initialized by the first control unit is less than the second duration initialized by the main chip.

[0007] In the above electronic device, since the first duration (usually less than 1 second) required for the initialization of the first control unit is less than the second duration (usually greater than or equal to 2 seconds) required for the initialization of the main chip, the delay in displaying the icon after power-on is reduced. The user does not need to wait for a long time to determine whether the electronic device has been powered on, avoiding redundant operations of the user to power on again and improving the user experience.

[0008] In a possible implementation, when receiving the first signal sent by the power-on detection unit, the first control unit sends the second signal to the main chip; when receiving the second signal sent by the first control unit, the main chip performs initialization.

[0009] In a possible implementation, the first control unit includes a system control unit and an icon display control unit. When receiving the first signal sent by the power-on detection unit, the system control unit sends an enable signal to the icon display control unit and sends the second signal to the main chip; when receiving the enable signal, the icon display control unit performs initialization, and the duration of the initialization of the icon display control unit is less than the second duration of the initialization of the main chip; when receiving the second signal sent by the system control unit, the main chip performs initialization.

[0010] In the above electronic device, the electronic device integrates the system control unit and the icon display control unit into the first control unit, thus streamlining the components of the electronic device and saving the cost of the electronic device. Moreover, since the initialization duration of the icon display control unit is less than the second duration of the initialization of the main chip, there is no need to wait for the main chip to complete initialization before displaying the icon, reducing the delay in displaying the icon after power-on and improving the user experience.

[0011] In a possible implementation, the system control unit and the icon display control unit are integrated into one body.

[0012] In the above electronic device, the electronic device can integrate the system control unit and the icon display control unit into one body, thus streamlining the components of the electronic device and saving the cost of the electronic device.

[0013] In a possible implementation, the electronic device includes an OR gate. The first control unit, the main chip, and the display power supply are connected through the OR gate. The first control unit is configured to send the third signal to the OR gate when initialization is completed. The OR gate is configured to send the received third signal to the display power supply.

[0014] In the above-mentioned electronic device, by adding an OR gate to connect the first control unit, the main chip, and the display power supply, not only can it ensure that the first control unit can independently supply power to the display power supply, but also it can not change the original structure of the electronic device (for example, the main chip supplies power to the display power supply), saving the cost of re-designing and assembling the electronic device.

[0015] In a possible implementation, the main chip is configured to send a second icon to the display driver chip when initialization is completed. The second icon is an icon stored in the memory of the main chip. The main chip is configured to send a first message to the first control unit. The first message instructs the main chip to send the second icon to the display driver chip. The first control unit is configured to send a fifth signal to the display driver chip according to the first message. The fifth signal is used to trigger the display panel to display the second icon.

[0016] In the above-mentioned electronic device, when the main chip completes initialization, the main chip can send a second icon to the display panel through the display driver chip, so that the display panel switches the displayed first icon to the second icon. The first icon and the second icon can be different, which can meet the usage requirements of displaying multiple icons and further improve the user experience.

[0017] In a possible implementation, the electronic device includes an OR gate. The first control unit, the main chip, and the display power supply are connected through the OR gate. The main chip is configured to send a sixth signal to the OR gate when initialization is completed. The sixth signal is used to enable the display power supply. The first control unit is configured to send a seventh signal to the OR gate according to the first message. The seventh signal is used to disable the display power supply. The OR gate is configured to send an eighth signal to the display power supply according to the sixth signal and the seventh signal. The eighth signal is the signal after performing an OR operation on the sixth signal and the seventh signal. The eighth signal is used to enable the display power supply.

[0018] In the above-mentioned electronic device, by adding an OR gate to connect the first control unit, the main chip, and the display power supply, the first control unit and the main chip can jointly control the enabling of the display power supply.

[0019] In a possible implementation, the fourth signal is different from the fifth signal. The fourth signal is a signal in a first state, and the fifth signal is a signal in a second state. The first state and the second state are different states of a signal for triggering an icon display.

[0020] In the above electronic device, the fourth signal may be an icon enable signal in an enabled state, the fifth signal may be an icon enable signal in a disabled state, the first state may be an enabled state, and the second state may be a disabled state. The electronic device can flexibly control the switching between the first icon and the second icon by controlling different states (enabled state and disabled state) of the icon enable signal. The time delay for switching between the two states of the icon enable signal is relatively low. Therefore, the switching rate between the first icon and the second icon is relatively fast, and the user is unaware of the switching, further enhancing the user experience.

[0021] In a possible implementation, the sixth signal is different from the seventh signal. The sixth signal is a signal in a third state, and the seventh signal is a signal in a fourth state. The third state and the fourth state are different states of a signal for enabling a display power supply.

[0022] In the above electronic device, the sixth signal is the same as the third signal. The sixth signal and the third signal may both be power enable signals in an enabled state, the seventh signal may be a power enable signal in a disabled state, the third state may be an enabled state, and the fourth state may be a disabled state. The electronic device can flexibly switch the power supply main body (main chip or first control unit) that provides power for the display power supply by controlling different states (enabled state and disabled state) of the power enable signal, so that only one power supply main body can supply power for the display power supply at the same time, reducing the power consumption of the electronic device.

[0023] In a possible implementation, the second duration for initializing the main chip is greater than the third duration, where the third duration is the sum of the duration for initializing the display module and the first duration for initializing the first control unit.

[0024] In the above electronic device, the duration for initializing the main chip may also be greater than the sum of the duration for initializing the first control unit and the duration for initializing the display module (including the display power supply, display driver chip, display panel, and memory). That is to say, when the display module completes initialization and displays the first icon, the main chip may just complete initialization. Therefore, the time delay for displaying the icon after power-on is greatly reduced, further enhancing the user experience.

[0052] Next, the technical solutions in the embodiments of this application will be described in conjunction with the accompanying drawings. Among them, in the description of the embodiments of this application, unless otherwise specified, " / " means "or". For example, A / B can mean A or B; "and / or" in the text is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist simultaneously, and B exists alone. In addition, in the description of the embodiments of this application, "a plurality" means two or more than two.

[0053] Hereinafter, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as implying or suggesting relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the embodiments of this application, unless otherwise specified, the meaning of "a plurality" is two or more than two.

[0054] Currently, after the electronic device is powered on and started up, the user can be prompted in the following two ways:

[0055] In Method 1, when the electronic device is equipped with a power indicator or keyboard indicator (such as but not limited to including keyboard backlight, special keyboard keys), after the electronic device receives the user's power-on operation, the power-on operation can be pressing the power button, or it can be other operations (such as opening the lid, etc.). The power indicator or keyboard indicator can be lit to prompt the user that the electronic device has been powered on. This method has a short time from receiving the power-on operation to lighting the power indicator or keyboard indicator (usually less than 1 second), and the user can perceive that the electronic device has been powered on without waiting. However, the effect of the power indicator or keyboard indicator is not obvious when lit during the day, and the user needs to specifically check to perceive that the light is on. It can be understood that the effect of the power-on reminder is not obvious.

[0056] In Method 2, after the electronic device receives the user's power-on operation, it can start up and display an icon (such as the trademark of the electronic device) on the display screen to prompt the user that the electronic device has been powered on. This method takes 3 seconds or even longer from receiving the power-on operation to displaying the icon on the display screen. It can be understood that the time delay for displaying the icon after power-on is relatively long. During this period, it is difficult for the user to perceive whether the electronic device has been powered on, resulting in the user may perform redundant operations such as pressing the power button again, and the user experience is poor.

[0057] This application provides a method that can quickly prompt the user that the device has been powered on, avoiding the user from performing redundant power-on operations again.

[0058] Figure 1 An exemplary schematic diagram of the hardware structure of an electronic device is shown.

[0059] As Figure 1 shown, the electronic device may include a memory 101 (including icon A), a main chip 102, an Embedded Controller (EC) chip 103, a power button 104, a display power supply 105, a display driver chip 106, a memory 107, a display panel 108, and a system power supply 109. Among them, the circuits and devices on the main chip 102 and the circuits and devices on the display power supply 105 can be connected by line 1, and the circuits and devices on the main chip 102 and the circuits and devices on the display driver chip 106 can be connected by line 2. Line 2 is, for example, a video protocol transmission bus.

[0060] The power button 104 can be used to receive the user's power-on operation, such as a pressing operation on the power button 104. The EC chip 103 can be used for the power management of the electronic device 100. The memory 101 can be used to store the firmware of the main chip 102, such as the information of icon A. The display power supply 105 can be used to provide power for the display driver chip 106, the memory 107, and the display panel 108. The memory 107 can be used to store the firmware of the display driver chip 106.

[0061] After the power button 104 receives a power-on operation, it can send signal 1 to the EC chip 103. After the EC chip 103 receives signal 1, it can control the system power supply 109 to supply power to the main chip 102. When the main chip 102 is powered on / energized, it can execute a series of operations to make the main chip 102 operate normally (which can be simply referred to as initialization). After the power-on initialization of the main chip 102 is completed, it can send a power enable signal (which can be called power signal 1) with an enable state to the display power supply 105 through line 1. The power signal 1 can be used to adjust the display power supply 105 to the enable state, so that the display power supply 105 completes initialization. The initialized display power supply 105 can supply power to the display driver chip 106, the memory 107, and the display panel 108, so that the display driver chip 106, the memory 107, and the display panel 108 complete initialization. Then, the main chip 102 can send the icon A in the memory 101 to the display driver chip 106 through line 2, and the display driver chip 106 can send the icon A to the display panel 108, and the display panel 108 displays the icon A.

[0062] Among them, based on Figure 1 In the implementation manner of the shown hardware structure, the time from when the power button 104 receives a power-on operation to when the main chip 102 completes initialization is relatively long. For example, the time required for the power button 104 to receive a power-on operation and the EC chip to control the system power supply to power on the main chip 102 is about 1 second, and the time required for the main chip 102 to initialize after being powered on is relatively long, usually greater than or equal to 2 seconds. As a result, the delay in displaying the icon A through the display panel 108 is relatively long (usually greater than or equal to 3 seconds), and the user needs to wait for a relatively long time to determine whether the electronic device has been powered on, resulting in a poor user experience.

[0063] An embodiment of the present application proposes a display method. This method is applied to an electronic device. By adding an additional control logic circuit, the electronic device can display an icon without waiting for the main chip to complete initialization after receiving a power-on operation. Instead, before the main chip completes initialization, the control logic circuit can control the display module to be powered on and complete initialization, thereby displaying the icon. Since the time required for the control logic circuit to initialize (usually less than 1 second) is less than the time required for the main chip to initialize (usually greater than or equal to 2 seconds), therefore, the delay in displaying the icon after power-on is reduced, and the user does not need to wait for a long time to determine whether the electronic device has been powered on. It can be understood that about one second after the user presses the power button, the user can determine that the current electronic device has been powered on through the icon lit on the display screen, rather than waiting for 3 seconds or even longer after pressing the power button to determine whether the electronic device has been powered on. This method solves the problem of long delay in displaying the icon after power-on, reduces the waiting time and anxiety of the user, and avoids the redundant operation of the user to power on again, improving the user experience.

[0064] In this application, the electronic device can be a mobile phone, a tablet computer, a handheld computer, a desktop computer, a laptop computer, an ultra-mobile personal computer (UMPC), a netbook, a cellular phone, a personal digital assistant (PDA), a smart home device such as a smart TV, a wearable device such as a smart bracelet, a smart watch, a smart glasses, an extended reality (XR) device such as an augmented reality (AR), a virtual reality (VR), a mixed reality (MR), a vehicle-mounted device or a smart city device, etc. This application does not impose special restrictions on the specific type of the electronic device.

[0065] Next, an exemplary introduction to the electronic device 100 involved in the embodiments of this application will be given.

[0066] Figure 2 An exemplary schematic diagram of the hardware structure of an electronic device 100 is shown.

[0067] As Figure 2 shown, the electronic device 100 may include a memory 201 (including icon B), a main chip 202, an icon display control unit 203, a system control unit 204, a power-on detection unit 205, an OR gate, and a display module 206. Among them, the display module 206 may include a display power supply 207, a display driver chip 208, a memory 209 (including icon C), and a display panel 210. The main chip 202, the icon display control unit 203, and the display power supply 207 may be connected through the OR gate. Among them, the main chip 202 and the OR gate may be connected through line 1, the icon display control unit 203 and the OR gate may be connected through line 3, the OR gate and the display power supply 207 may be connected through line 5, the circuits and devices on the main chip 202 and the circuits and devices on the display driver chip 208 may be connected through line 2, and the circuits and devices on the icon display control unit 203 and the circuits and devices on the display driver chip 208 may be connected through line 4. Among them:

[0068] The main chip 202 can be used to perform task calculation and management, graphics service processing, etc. The main chip 202 is, for example but not limited to, a System-on-Chip (SOC) based on the ARM architecture (which can be abbreviated as ARM SOC), an SOC based on the MIPS (Microprocessor without interlocked piped stages) architecture (which can be abbreviated as MIPS SOC), or an SOC based on the Intel x86 architecture (which can be abbreviated as x86 SOC).

[0069] The memory 201 can be used to store the firmware of the main chip 202, such as the information of icon B. The memory 201 is, for example, a non-volatile memory based on the input / output system (BIOS NOR Flash).

[0070] The system control unit 204 can be used to control external input devices of the system (such as keyboards and mice), sensors, power supplies, etc. The system control unit 204 can be used to supply power to the icon display control unit 203, the main chip 202, and the memory 201. The system control unit 204 is, for example but not limited to, a Microcontroller Unit (MCU), an Embedded Controller (EC), or an integrated chip of an MCU and a power supply.

[0071] The icon display control unit 203 can be a single-chip microcomputer.

[0072] The power-on detection unit 205 can be used to receive the user's power-on operation, such as the user's pressing operation on the power button, or the user's open-lid operation on the electronic device 100 detected by the Hall sensor.

[0073] The OR gate can be an OR logic digital gate circuit chip. The OR gate can be integrated into the icon display control unit 203 or exist independently.

[0074] The display power supply 207 can be used to supply power to the display driver chip 106, the memory 107, and the display panel 108.

[0075] The display driver chip 208 can be used to process the received image data and send it to the display panel 210 so that the display panel 210 can display the image data. The display driver chip 208 can include at least one chip.

[0076] The memory 209 can be used to store the firmware of the display driver chip 208, such as the information of icon C. The memory 209 is, for example, a non-volatile memory based on the timing controller (TCON NOR Flash).

[0077] The display panel 210 can be used to output image data. The display panel 210 is, for example, a liquid crystal display (LCD) or an organic light-emitting diode (OLED).

[0078] After the power-on detection unit 205 receives a power-on operation, it can send signal 2 to the system control unit 204. After the system control unit 204 receives signal 2, it can supply power to the icon display control unit 203 and the main chip 202. When the icon display control unit 203 and the main chip 202 are powered on / energized, they can be initialized respectively. Among them, the initialization duration of the main chip 202 is longer than that of the icon display control unit 203. When the power-on initialization of the icon display control unit 203 is completed, it can send power signal 1 to the display power supply 207 through line 3. Power signal 1 is, for example, a high level. Power signal 1 can be used to adjust the display power supply 207 to the enabled state so that the display power supply 207 completes initialization. The initialized display power supply 207 can supply power to the display driver chip 208, the memory 209, and the display panel 210 in the display module 206 to power them on and complete initialization. At the same time, the icon display control unit 203 can send an enabled icon enable signal (which can be called icon signal 1) in the enabled state to the display driver chip 208 through line 4. After the display driver chip 208 completes initialization and detects icon signal 1, it can send icon C in the memory 209 to the display panel 210, and the display panel 210 displays the icon C. When the power-on initialization of the main chip 202 is completed, the main chip 202 can send power signal 1 (such as a high level) to the display power supply 207 through line 1 and send icon B in the memory 201 to the display driver chip 208 through line 2. In one implementation, the main chip 202 can also send indication information to the icon display control unit 203, indicating that the main chip 202 has sent icon B to the display driver chip 208. After receiving the indication information, the icon display control unit 203 can send a disabled power enable signal (which can be called power signal 2) in the disabled state to the display power supply 207 through line 3 and send a disabled icon enable signal (which can be called icon signal 2) in the disabled state to the display driver chip 208 through line 4. It can be understood that the enabled state of the power enable signal is switched to the disabled state and the enabled state of the icon enable signal is switched to the disabled state. After the display driver chip 208 detects icon signal 2, it can send icon B to the display panel 210, and the display panel 210 switches the displayed icon A to icon B.

[0079] It can be understood that Figure 2The hardware structure diagram of the electronic device 100 shown may include more or fewer modules. Any one of the modules in the hardware structure diagram can be a hardware module or a software module. Any one of the above modules can be a separate module, and at least one of the above modules can also be integrated together. For example, the icon display control unit 203 can be integrated into the system control unit 204. Another example is that the memory 201 can be integrated into the main chip 202. Another example is that the memory 209 can be integrated into the display driver chip 208. Another example is that the OR gate can be integrated into the icon display control unit 203. This application does not make any limitations in this regard. This application does not limit the name of any one of the above modules, and it can also be other names for implementing the functions corresponding to any one of the above modules.

[0080] Figure 3 Exemplarily shown is another schematic diagram of the hardware structure of the electronic device 100.

[0081] Figure 3 and Figure 2 The hardware structure of the electronic device 100 shown is similar, except that Figure 3 the icon display control unit 203 in Figure 3 has been integrated into the system control unit 301. For the description of any one of the modules in Figure 2 reference can be made to the description of the corresponding module in

[0082] Figure 4 Exemplarily shown is another schematic diagram of the hardware structure of the electronic device 100.

[0083] Figure 4 and Figure 3 The hardware structure of the electronic device 100 shown is similar, except that Figure 4 it does not include the OR gate, the line 1 between the main chip 202 and the OR gate, and the line 5 between the OR gate and the display power supply 207. For the description of any one of the modules in Figure 4 reference can be made to the description of the corresponding module in Figure 3 and details will not be repeated.

[0084] Not limited to this, in another embodiment, the hardware structure of the electronic device 100 and Figure 4 the hardware structure of the electronic device 100 shown are similar, except that the icon display control unit 203 may not be integrated into the system control unit 301.

[0085] In Figure 2 , Figure 3 and Figure 4In the hardware structure shown, the electronic device adds a system control unit and / or an icon display control unit. When the initialization of the system control unit / icon display control unit is completed, the display module can be powered on and initialized, thereby displaying icons. Since the time required for the initialization of the system control unit / icon display control unit is less than the time required for the initialization of the main chip, it is not necessary to wait for the initialization of the main chip to be completed before displaying icons. Instead, icons can be displayed before the initialization of the main chip is completed (after the initialization of the system control unit / icon display control unit is completed). In this way, the initialization of the display module is decoupled from the initialization of the main chip, and the independent initialization time of the system control unit / icon display control unit is shorter, thereby reducing the delay in displaying icons after startup, reducing the waiting time and anxiety of the user, avoiding redundant operations of the user to power on again, and improving the user experience.

[0086] Figure 5 Exemplarily shows a schematic diagram of the hardware structure of another electronic device 100.

[0087] Figure 5 and Figure 4 is similar to the hardware structure of the electronic device 100 shown, the difference is that Figure 5 the system control unit 301 and the icon display control unit 203 in Figure 5 are both integrated into the main chip 501, and the description of any module in Figure 4 can be referred to the description of the corresponding module in

[0088] In Figure 5 In the hardware structure shown, the electronic device integrates the added system control unit and / or icon display control unit into the main chip, which simplifies the components of the electronic device and saves the cost of the electronic device. Moreover, the system control unit / icon display control unit can be initialized independently of the main chip, so it is not necessary to wait for the initialization of the main chip to be completed before displaying icons, reducing the delay in displaying icons after startup and improving the user experience.

At this time, the main chip can send a high level to the display power supply through line 1, and the system control unit can send a high level to the display power supply through line 3. These two high levels remain high level (power signal 1) after passing through the OR gate.

[0135] In one embodiment, the initialization duration of the main chip is the second duration, and the second duration is greater than the first duration (the initialization duration of the above-mentioned system control unit). Optionally, the second duration can also be greater than the third duration, where the third duration can be the sum of the first duration and the initialization duration of the display module (including the display power supply, the display driver chip, the display panel, and the memory).

[0149] S121: The system control unit sends a power enable signal in a prohibited state to the display power supply.

[0150] In one embodiment, S121 is an optional step.

[0151] In one embodiment, the power enable signal in a prohibited state (which can be referred to as Power Signal 2) can be used to adjust the display power supply to a non-enabled state. Power Signal 2 is different from Power Signal 1, for example, the high and low levels are different.

[0152] In one embodiment, after receiving the first message, the system control unit can send a power signal 2 to the display power supply. It can be understood that the system control unit switches the enabling state of the power enable signal to the disabled state.

At this time, the system control unit can send a low level to the display power supply through line 3, and the main chip can send a high level to the display power supply through line 1. After passing through the OR gate, the high level and the low level are still a high level (power signal 1). It can be understood that at this time, the system control unit no longer controls the display power supply to supply power to the display driver chip, the display panel, and the memory in the display module, and only the main chip controls the display power supply to supply power to the display driver chip, the display panel, and the memory.

[0154] S122: The system control unit sends an icon enable signal in the disabled state to the display driver chip.

[0155] In one embodiment, S122 is an optional step.

[0156] In one embodiment, the icon enable signal in the disabled state (which can be called icon signal 2) can be used for the display driver chip to select an icon (assumed to be icon 2) stored in the memory of the main chip.

[0166] In one embodiment, S125 is an optional step.

[0167] In one embodiment, after receiving icon 2 sent by the display driving chip, the display panel can display icon 2. It can be understood that the display panel switches the displayed icon 1 to icon 2.

[0168] In Figure 6 In the method shown, by controlling different states (enabled state and disabled state) of the icon enable signal, the switching between icon 1 and icon 2 can be flexibly controlled. The time delay for switching between the two states of the icon enable signal is relatively low. Therefore, the switching rate between icon 1 and icon 2 is relatively fast, and the user has no perception of the switching, further improving the user experience.

[0169] The above embodiments are described by taking the hardware structure of the electronic device 100 shown in Figure 3 as an example. In another embodiment, the hardware structure of the electronic device 100 shown in Figure 2 can also be taken as an example. Based on the steps of the embodiment with the hardware structure shown in Figure 2 and the steps of the embodiment shown in Figure 6 are similar. The difference is that the system control unit can supply power to the icon display control unit and the main chip, so that the icon display control unit and the main chip are powered on and initialized respectively. Subsequently, the icon display control unit and the display module interact to make the display panel display icon 2.

[0170] The above embodiments are described by taking the hardware structure of the electronic device 100 shown in Figure 3 as an example. In another embodiment, the hardware structure of the electronic device 100 shown in Figure 4 can also be taken as an example. Based on the steps of the embodiment with the hardware structure shown in Figure 4 and the steps of the embodiment shown in Figure 6 are similar. The difference is that Figure 4 the embodiment shown does not include Figure 6 S115 - S117 and S120. That is to say, only the system control unit controls the display power supply to supply power to the display driving chip, the display panel, and the memory in the display module. In this way, the components (OR gates, line 1, and line 5) of the electronic device can be streamlined, the cost of the electronic device can be saved, the time for interaction between internal modules of the electronic device can be reduced, and further the time delay for displaying icons after power-on can be reduced, improving the user experience.

[0241] In one implementation, the second duration of the main chip initialization is greater than the third duration, and the third duration is the sum of the initialization duration of the display module and the first duration. For the specific description, refer to Figure 6 the description in S116, which will not be elaborated here.

[0242] In Figure 8 the method shown, the electronic device adds a first control unit. When the initialization of the first control unit is completed, the display module can be powered on and initialized, so as to display the icon. Since the time required for the initialization of the first control unit is less than the time required for the initialization of the main chip, therefore, there is no need to wait for the initialization of the main chip to be completed before the icon can be displayed. Instead, the icon can be displayed before the initialization of the main chip is completed (after the initialization of the first control unit is completed). In this way, the initialization of the display module and the initialization of the main chip are decoupled, and the independent initialization time of the first control unit is shorter, thereby reducing the delay of displaying the icon after power-on, reducing the waiting time and anxiety of the user, avoiding the redundant operation of the user to power on again, and improving the user experience.
