Description

Display method and electronic device

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of China on December 28, 2023, with application number 202311852655.7, and priority to the Chinese patent application entitled "A Display Method and Electronic Device", all contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of computer technology, and in particular to a display method and electronic device. Background Art

[0003] Currently, after receiving a power-on command from a user, an electronic device can start up and display an icon on the display to inform the user that the electronic device has started up. However, it can take three seconds or even longer for the electronic device to receive the power-on command and display the icon on the display. During this time, it is difficult for the user to know whether the electronic device has started up. This may cause the user to perform invalid power-on operations such as pressing the power button again, resulting in a poor user experience. Summary of the Invention

[0004] The present application discloses a display method and an electronic device, which can reduce the delay in displaying icons after power-on, reduce the user's waiting time and anxiety, promptly remind the user of the power-on status of the electronic device, avoid the user from performing redundant power-on operations again, and improve the user experience.

[0005] In a first aspect, an embodiment of the present application provides an electronic device, comprising a power-on detection unit, a main chip, a first control unit and a display module, wherein the display module comprises a display power supply, a display driver chip and a display panel, wherein the first control unit is configured to perform initialization upon receiving a first signal sent by the power-on detection unit, and the first signal is used to instruct the electronic device to start powering on; the main chip is configured to perform initialization upon 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 upon completion of initialization, 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 upon completion of initialization, 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.

[0006] In the electronic device described above, a first control unit is added to the electronic device so that after receiving the first signal, the electronic device does not need to wait for the main chip to be initialized before displaying the icon. Instead, the electronic device can control the display module to power on and complete initialization through the first control unit before the main chip is initialized (after the first control unit is initialized), thereby displaying the first icon. The electronic device decouples the initialization of the display module from the initialization of the main chip, and the first control unit takes a shorter time to independently initialize, thereby reducing the delay in displaying the icon after powering on, reducing the user's waiting time and anxiety, avoiding the user from performing redundant power-on operations again, and improving the user experience.

[0007] In a possible implementation, a first duration of initialization of the first control unit is shorter than a second duration of initialization of the main chip.

[0008] In the above-mentioned electronic device, since the first time required for initialization of the first control unit (usually less than 1 second) is less than the second time required for initialization of the main chip (usually greater than or equal to 2 seconds), the delay in displaying the icon after startup is reduced, and the user does not need to wait for a long time to determine whether the electronic device has been started, avoiding the user from performing redundant startup operations again, thereby improving the user experience.

[0009] In one possible implementation, the first control unit is configured to send the second signal to the main chip upon receiving the first signal sent by the power-on detection unit; and the main chip is configured to perform initialization upon receiving the second signal sent by the first control unit.

[0010] In one possible implementation, the first control unit includes a system control unit and an icon display control unit. The system control unit is used to send an enable signal to the icon display control unit and send the second signal to the main chip when receiving the first signal sent by the power-on detection unit; the icon display control unit is used to initialize when receiving the enable signal, and the initialization duration of the icon display control unit is less than the second initialization duration of the main chip; the main chip is used to initialize when receiving the second signal sent by the system control unit.

[0011] In the electronic device described above, the system control unit and the icon display control unit are integrated into the first control unit, thus streamlining the electronic device's components and reducing its cost. Furthermore, the initialization duration of the icon display control unit is shorter than the second initialization duration of the main chip. Therefore, there is no need to wait for the main chip to initialize before icons can be displayed. This reduces the delay in icon display after power-on and improves the user experience.

[0012] In a possible implementation manner, the system control unit and the icon display control unit are integrated into one.

[0013] In the above electronic device, the electronic device can integrate the electronic device system control unit and the icon display control unit into one body, thereby streamlining the components of the electronic device and saving the cost of the electronic device.

[0014] In one possible implementation, the electronic device includes an OR gate, and the first control unit, the main chip and the display power supply are connected through the OR gate. The first control unit is used to send the third signal to the OR gate when initialization is completed; and the OR gate is used to send the received third signal to the display power supply.

[0015] In the above-mentioned electronic device, the electronic device is connected to the first control unit, the main chip and the display power supply by adding an OR gate, which not only ensures that the first control unit can independently provide power for the display power supply, but also does not change the original structure of the electronic device (for example, the main chip provides power for the display power supply), thereby saving the cost of redesigning and assembling the electronic device.

[0016] In one possible implementation, the main chip is used to send a second icon to the display driver chip when initialization is completed, and the second icon is an icon stored in the memory of the main chip; the main chip is used to send a first message to the first control unit, and the first message instructs the main chip to send the second icon to the display driver chip; the first control unit is used to send a fifth signal to the display driver chip according to the first message, and the fifth signal is used to trigger the display panel to display the second icon.

[0017] In the above-mentioned electronic device, when the main chip is initialized, the main chip can send a second icon to the display panel through the display driver chip, so that the display panel switches the first icon displayed to the second icon. The first icon and the second icon can be different, which can meet the use requirements of displaying multiple icons and further enhance the user experience.

[0018] In one possible implementation, the electronic device includes an OR gate, and the first control unit, the main chip and the display power supply are connected through the OR gate. The main chip is used to send a sixth signal to the OR gate when initialization is completed, and the sixth signal is used to enable the display power supply; the first control unit is used to send a seventh signal to the OR gate according to the first message, and the seventh signal is used to disable the display power supply; the OR gate is used to send an eighth signal to the display power supply according to the sixth signal and the seventh signal, and the eighth signal is a signal after the sixth signal and the seventh signal are ORed, and the eighth signal is used to enable the display power supply.

[0019] In the above electronic device, the electronic device is connected to the first control unit, the main chip and the display power supply by adding an OR gate, and the first control unit and the main chip can jointly control the display power supply to be enabled.

[0020] In one possible implementation, the fourth signal and the fifth signal are different, the fourth signal is a signal in a first state, the fifth signal is a signal in a second state, and the first state and the second state are different states of the signal used to trigger the display of the icon.

[0021] 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 the 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 low, so the switching rate between the first icon and the second icon is fast, and the user does not perceive the switching, further improving the user experience.

[0022] In one possible implementation, the sixth signal and the seventh signal are different, the sixth signal is a signal in the third state, the seventh signal is a signal in the fourth state, and the third state and the fourth state are different states of the signal for enabling the display power supply.

[0023] In the above-described electronic device, the sixth signal and the third signal are the same, and the sixth signal and the third signal can both be power enable signals in an enabled state, the seventh signal can be a power enable signal in a disabled state, the third state can be an enabled state, and the fourth state can be a disabled state. By controlling the different states (enabled state and disabled state) of the power enable signal, the electronic device can flexibly switch the power supply entity (main chip or first control unit) that provides power to the display power supply, thereby enabling only one power supply entity to supply power to the display power supply at a time, thereby reducing the power consumption of the electronic device.

[0024] In a possible implementation, the second duration of the main chip initialization is greater than a third duration, and the third duration is the sum of the duration of the display module initialization and the first duration of the first control unit initialization.

[0025] In the above-mentioned electronic device, the duration of the main chip initialization can also be greater than the sum of the duration of the first control unit initialization and the duration of the display module (including display power supply, display driver chip, display panel and memory) initialization. That is to say, when the display module is initialized and displays the first icon, the main chip may have completed initialization. Therefore, the delay in displaying the icon after power-on is greatly reduced, further improving the user experience.

[0026] In a second aspect, an embodiment of the present application provides a display method, which is applied to an electronic device, wherein the electronic device includes a power-on detection unit, a main chip, a first control unit and a display module, and the display module includes a display power supply, a display driver chip and a display panel.

[0030] In a possible implementation manner, the system control unit and the icon display control unit are integrated into one.

[0031] In one possible implementation, the electronic device includes an OR gate, and the first control unit, the main chip, and the display power supply are connected through the OR gate. The method also includes: when the first control unit is initialized, the first control unit sends the third signal to the OR gate; and the OR gate sends the received third signal to the display power supply.

[0055] Currently, after an electronic device is powered on, it can prompt the user in the following two ways:

[0056] Method 1: When the electronic device is equipped with a power indicator light or a keyboard indicator light (for example, but not limited to, a keyboard backlight and special keyboard keys), when the electronic device receives a power-on operation from the user, which can be pressing the power button or other operations (such as opening the cover, etc.), the power indicator light or the keyboard indicator light can be turned on to remind the user that the electronic device has been started. In this method, the time from receiving the power-on operation to lighting up the power indicator light or the keyboard indicator light is short (usually less than 1 second), and the user can perceive that the electronic device has been started without waiting. However, the power indicator light or the keyboard indicator light is not obvious when it is on during the day, and the user needs to check it specially to perceive that the light is on. It can be understood that the effect of the power-on reminder is not obvious.

[0057] Method 2: After the electronic device receives the power-on operation from the user, 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 started up. 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 delay in displaying the icon after powering on is long. During this period, it is difficult for the user to perceive whether the electronic device has started up, which may cause the user to perform redundant operations such as pressing the power button again, resulting in a poor user experience.

[0058] The present application provides a method that can quickly prompt the user that the power-on has been initiated, thereby avoiding the user from performing redundant power-on operations again.

[0059] FIG1 exemplarily shows a schematic diagram of the hardware structure of an electronic device.

[0060] As shown in Figure 1, 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, wherein the circuits and devices on the main chip 102 and the circuits and devices on the display power supply 105 can be connected via 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 via line 2, and line 2 is, for example, a video protocol transmission bus.

[0061] The power button 104 can be used to receive a user power-on operation, such as a press of the power button 104. The EC chip 103 can be used to manage the power supply 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 to 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.

[0062] After the power button 104 receives the power-on operation, it can send signal 1 to the EC chip 103. After receiving signal 1, the EC chip 103 can control the system power supply 109 to provide power to the main chip 102. When the main chip 102 is powered on / powered on, a series of operations can be performed to enable the main chip 102 to operate normally (which can be simply referred to as initialization). After the main chip 102 is powered on and initialized, it can send a power enable signal (which can be referred to as power signal 1) in an enable state to the display power supply 105 through line 1. Power signal 1 can be used to adjust the display power supply 105 to an enabled state so that the display power supply 105 completes initialization. The initialized display power supply 105 can provide 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. Next, the main chip 102 can send icon A in the memory 101 to the display driver chip 106 through line 2. The display driver chip 106 can send the icon A to the display panel 108, and the display panel 108 displays the icon A.

[0063] Among them, the implementation method based on the hardware structure shown in Figure 1 has a long time from the power button 104 receiving the power-on operation to the completion of the initialization of the main chip 102. For example, the time required for the power button 104 to receive the power-on operation and the EC chip control system power to power on the main chip 102 is about 1 second, and the time required for the main chip 102 to initialize after powering on is relatively long, usually greater than or equal to 2 seconds, resulting in a long delay in displaying icon A through the display panel 108 (usually greater than or equal to 3 seconds). The user needs to wait for a long time to determine whether the electronic device has been started, resulting in a poor user experience.

[0064] The embodiment of the present application proposes a display method, which is applied to an electronic device. The method adds an additional control logic circuit so that after the electronic device receives the power-on operation, it does not need to wait for the main chip to be initialized before displaying the icon. Instead, the control logic circuit can be used to control the display module to power on and complete the initialization before the main chip is initialized, thereby displaying the icon. Because 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), the delay in displaying the icon after powering on is reduced, and the user does not need to wait for a long time to determine whether the electronic device has been started. It can be understood that the user can determine that the current electronic device is powered on by the icon that lights up on the display screen for about one second after pressing the power button, without having to wait for 3 seconds or even longer after pressing the power button to determine whether the electronic device is powered on. This method solves the problem of a long delay in displaying the icon after powering on, reduces the user's waiting time and anxiety, avoids the user from performing redundant power-on operations again, and improves the user experience.

[0065] In this application, the electronic device may 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), smart home devices such as smart TVs, wearable devices such as smart bracelets, smart watches, and smart glasses, extended reality (XR) devices such as augmented reality (AR), virtual reality (VR), and mixed reality (MR), in-vehicle devices or smart city devices, etc. This application does not impose any special restrictions on the specific types of electronic devices.

[0066] The electronic device 100 involved in the embodiment of the present application is exemplarily introduced below.

[0067] FIG2 exemplarily shows a schematic diagram of the hardware structure of an electronic device 100 .

[0068] As shown in Figure 2, 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, wherein 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 an OR gate, wherein 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 may be connected to 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 may be connected to the circuits and devices on the display driver chip 208 may be connected through line 4. Wherein:

[0069] The main chip 202 can be used to perform task calculation and management, graphics business processing, etc. The main chip 202 is, for example but not limited to, an integrated system-on-chip (System-on-Chip, SOC) based on ARM architecture (referred to as ARM SOC), a SOC based on MIPS (Microprocessor without interlocked piped stages) architecture (referred to as MIPS SOC), and a SOC based on Intel x86 architecture (referred to as x86 SOC).

[0070] The memory 201 may be used to store the firmware of the main chip 202 , such as the information in the icon B. The memory 201 is, for example, a non-volatile memory (BIOS NOR Flash) based on an input / output system.

[0071] The system control unit 204 can be used to control external input devices (such as a keyboard and mouse), sensors, power supplies, etc. The system control unit 204 can be used to provide power to the icon display control unit 203, the main chip 202, and the memory 201. The system control unit 204 can be, for example, but not limited to, a microcontroller unit (MCU), an embedded controller (EC), an MCU, and a power integrated chip.

[0072] The icon display control unit 203 may be a single chip microcomputer.

[0073] The power-on detection unit 205 may be configured to receive a power-on operation from a user, such as a power button press by a user, or a cover-opening operation of the electronic device 100 by a user detected by a Hall sensor.

[0074] The OR gate may be an OR logic digital gate circuit chip. The OR gate may be integrated into the icon display control unit 203 or exist independently.

[0075] The display power supply 207 can be used to provide power to the display driver chip 106 , the memory 107 and the display panel 108 .

[0076] The display driver chip 208 may be configured to process the received image data and send the received image data to the display panel 210 so that the display panel 210 displays the image data. The display driver chip 208 may include at least one chip.

[0077] The memory 209 may be used to store the firmware of the display driver chip 208 , such as information of icon C. The memory 209 is, for example, a non-volatile memory (TCON NOR Flash) based on a timing controller.

[0078] The display panel 210 may be used to output image data. The display panel 210 may be, for example, a liquid crystal display (LCD) or an organic light-emitting diode (OLED).

[0079] After receiving the power-on operation, the power-on detection unit 205 can send signal 2 to the system control unit 204. After receiving signal 2, the system control unit 204 can provide 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 / powered on, they can be initialized respectively. Among them, the initialization time of the main chip 202 is longer than the initialization time of the icon display control unit 203. When the icon display control unit 203 completes power-on initialization, it can send a power signal 1 to the display power supply 207 via 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 an enabled state, so that the display power supply 207 completes initialization. The initialized display power supply 207 can provide power to the display driver chip 208, memory 209, and display panel 210 in the display module 206, so that they can power on and complete initialization. At the same time, the icon display control unit 203 can send an icon enable signal (referred to as icon signal 1) to the display driver chip 208 via line 4. After the display driver chip 208 completes initialization and detects icon signal 1, it can send icon C in memory 209 to the display panel 210, which then displays icon C. When the main chip 202 completes power-on initialization, the main chip 202 can send a power signal 1 (e.g., a high level) to the display power supply 207 via line 1, and send icon B in memory 201 to the display driver chip 208 via line 2. In one embodiment, the main chip 202 may also send an indication message 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 message, the icon display control unit 203 may send a power enable signal (referred to as power signal 2) in a disabled state to the display power supply 207 via line 3, and send an icon enable signal (referred to as icon signal 2) in a disabled state to the display driver chip 208 via line 4. This may be understood as switching the enabled state of the power enable signal to a disabled state and switching the enabled state of the icon enable signal to a disabled state. After the display driver chip 208 detects icon signal 2, it may send icon B to the display panel 210, and the display panel 210 switches the displayed icon A to icon B.

[0080] It can be understood that the hardware structure diagram of the electronic device 100 shown in Figure 2 may include more or fewer modules, and any module in the hardware structure diagram may be a hardware module or a software module. Any of the above modules may be a separate module, and at least one of the above modules may also be integrated together. For example, the icon display control unit 203 may be integrated into the system control unit 204, and for another example, the memory 201 may be integrated into the main chip 202, and for another example, the memory 209 may be integrated into the display driver chip 208, and for another example, the OR gate may be integrated into the icon display control unit 203.

This application does not limit the name of any of the above modules, and it can also be other names to implement the functions corresponding to any of the above modules.

[0081] FIG3 exemplarily shows a schematic diagram of the hardware structure of another electronic device 100 .

[0082] The hardware structure of the electronic device 100 shown in Figure 3 is similar to that of Figure 2. The difference is that the icon display control unit 203 in Figure 3 has been integrated into the system control unit 301. The description of any module in Figure 3 can be found in the description of the corresponding module in Figure 2, and no further details are given.

[0083] FIG4 exemplarily shows a schematic diagram of the hardware structure of another electronic device 100 .

[0084] The hardware structure of the electronic device 100 shown in Figure 4 is similar to that of Figure 3, except that Figure 4 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. The description of any module in Figure 4 can be found in the description of the corresponding module in Figure 3, and no further details will be given.

[0085] Without limitation thereto, in another embodiment, the hardware structure of the electronic device 100 is similar to the hardware structure of the electronic device 100 shown in FIG. 4 , except that the icon display control unit 203 may not be integrated into the system control unit 301 .

[0086] In the hardware structure shown in Figures 2, 3 and 4, the electronic device has added a system control unit and / or an icon display control unit. When the system control unit / icon display control unit is initialized, the display module can be powered on and initialized to display the icon. Since the time required for the system control unit / icon display control unit to initialize is less than the time required for the main chip to initialize, there is no need to wait for the main chip to initialize before the icon can be displayed. Instead, the icon can be displayed before the main chip is initialized (after the system control unit / icon display control unit is initialized). In this way, the initialization of the display module and the initialization of the main chip are decoupled, and the time for the system control unit / icon display control unit to initialize independently is shorter, thereby reducing the delay in displaying the icon after powering on, reducing the user's waiting time and anxiety, avoiding the user from performing redundant power-on operations again, and improving the user experience.

[0087] FIG5 exemplarily shows a schematic diagram of the hardware structure of another electronic device 100 .

[0088] The hardware structure of the electronic device 100 shown in Figure 5 is similar to that of Figure 4. The difference is that the system control unit 301 and the icon display control unit 203 in Figure 5 are both integrated into the main chip 501. The description of any module in Figure 5 can be found in the description of the corresponding module in Figure 4, and no further details are given.

[0089] In the hardware structure shown in Figure 5, the electronic device integrates the additional system control unit and / or icon display control unit into the main chip, streamlining the electronic device's components and reducing costs. Furthermore, the system control unit / icon display control unit can be initialized independently of the main chip, eliminating the need to wait for the main chip to initialize before displaying icons. This reduces the delay in icon display after power-up and improves the user experience.

[0121] In one embodiment, icon signal 1 (icon enable signal in enabled state) can be used to display the icon (assuming it is icon 1) stored in the memory of the driver chip selection display module.

[0134] In one embodiment, after the main chip is powered on and initialized, the main chip may send a power signal 1 to the display power supply, so that the display power supply provides power to the display driver chip, display panel, and memory in the display module.

[0135] In one embodiment, the power signal 1 is, for example, a high level. 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 are still high levels (power signal 1) after passing through the OR gate.

[0136] In one embodiment, the duration of the main chip initialization is a second duration, and the second duration is greater than the first duration (the duration of the system control unit initialization). Optionally, the second duration may also be greater than a third duration, wherein the third duration may be the sum of the first duration and the duration of the display module (including the display power supply, display driver chip, display panel, and memory) initialization.

The video protocol transmission bus is, for example but not limited to, an eDP interface or a MIPI interface.

[0147] S120: The main chip sends a first message to the system control unit.

[0148] In one embodiment, S120 is an optional step.

[0150] S121: The system control unit sends a power enable signal in a disabled state to the display power supply.

[0151] In one embodiment, S121 is an optional step.

[0152] In one embodiment, the disabled power enable signal (referred to as power signal 2 ) can be used to indicate that the power is adjusted to the disabled state. Power signal 2 is different from power signal 1 , for example, the high and low levels are different.

[0154] In one embodiment, for example, if power signal 2 is at a low level, the system control unit can send a low level to the display power supply via line 3, and the main chip can send a high level to the display power supply via line 1. After the high level and the low level pass through the OR gate, they are still high (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, display panel, and memory in the display module. Only the main chip controls the display power supply to supply power to the display driver chip, display panel, and memory.

[0155] S122: The system control unit sends a disabled icon enable signal to the display driver chip.

[0156] In one embodiment, S122 is an optional step.

[0157] In one embodiment, the icon enable signal in the disabled state (which may be referred to as icon signal 2) can be used to display the driver chip to select the icon (assuming it is icon 2) stored in the memory of the main chip. Icon signal 2 is different from icon signal 1, for example, the high and low levels are different. Icon signal 2 is, for example, a low level. The system control unit can send a low level to the display driver chip through line 4.

[0158] In one embodiment, after receiving the first message, the system control unit may send an icon signal 2 to the display driver chip, which can be understood as the system control unit switching the enable state of the icon enable signal to a disable state.

[0166] S125: The display panel displays icon 2.

[0167] In one embodiment, S125 is an optional step.

[0168] In one embodiment, after receiving the icon 2 sent by the display driver chip, the display panel may display the icon 2 . This can be understood as the display panel switching the displayed icon 1 to the icon 2 .

[0169] In the method shown in Figure 6, by controlling the different states (enabled state and disabled state) of the icon enable signal, the switching of icon 1 and icon 2 can be flexibly controlled. The delay of switching between the two states of the icon enable signal is low, so the switching rate of icon 1 and icon 2 is fast, and the user is unaware of the switching, which further improves the user experience.

[0170] The above embodiment is described using 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 used as an example. The steps of the embodiment based on the hardware structure shown in Figure 2 are similar to the steps of the embodiment shown in Figure 6. The difference is that the system control unit can provide 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 so that the display panel displays icon 2.

[0171] The above embodiment is described using the hardware structure of the electronic device 100 shown in FIG3 as an example. In another embodiment, the hardware structure of the electronic device 100 shown in FIG4 can also be used as an example for description. The steps of the embodiment based on the hardware structure shown in FIG4 are similar to the steps of the embodiment shown in FIG6 , except that the embodiment shown in FIG4 does not include S115-S117 and S120 of FIG6 , that is, only the system control unit controls the display power supply to supply power to the display driver chip, display panel, and memory in the display module. In this way, the devices of the electronic device (or gate, line 1, and line 5) can be streamlined, the cost of the electronic device can be saved, the time for interaction between the internal modules of the electronic device can be reduced, the delay in displaying the icon after startup can be further reduced, and the user experience can be improved.

The first message indicates that the master chip has sent the second icon to the display driver chip, and the fifth signal is used to trigger the display panel to display the second icon. For specific explanations, see the explanations of S119-S120 and S123-S125 of FIG6 , which will not be repeated here.

[0239] In one embodiment, after S304, when the main chip is initialized, the main chip can send a sixth signal to the OR gate. The first control unit can send a seventh signal to the OR gate based on the first message. The OR gate sends an eighth signal to the display power supply based on the sixth and seventh signals. The sixth signal is used to display power enable, the seventh signal is used to display power disable, and the eighth signal is a signal obtained by performing an OR operation on the sixth and seventh signals. The eighth signal is used to display power enable. For specific details, please refer to the descriptions of S116-S118 and S120-S122 in Figure 6, which will not be repeated here.

[0240] In one embodiment, the fourth signal and the fifth signal are different. The fourth signal is a signal of the first state, and the fifth signal is a signal of the second state. The first state and the second state are different states of the signal for triggering the display of the icon. The first state is, for example, an enabled state, and the second state is, for example, a disabled state. For the description of the fourth signal, please refer to the description of icon signal 1 in S112 of Figure 6, and for the description of the fifth signal, please refer to the description of icon signal 2 in S122 of Figure 6, and no further details will be given.

[0241] In one embodiment, the sixth signal and the seventh signal are different. The sixth signal is a signal in the third state, and the seventh signal is a signal in the fourth state. The third state and the fourth state are different states of the signal for enabling the display power supply. The third state is, for example, an enabled state, and the fourth state is, for example, a disabled state. For the description of the sixth signal, refer to the description of the power signal 1 in S106 of Figure 6, and for the description of the seventh signal, refer to the description of the power signal 2 in S121 of Figure 6, which will not be repeated here.

[0242] In one embodiment, the second duration of the main chip initialization is greater than the third duration, and the third duration is the sum of the duration of the display module initialization and the first duration. For specific details, please refer to the description in S116 of Figure 6 and will not be repeated here.

[0243] In the method shown in FIG8 , a first control unit is added to the electronic device. When the initialization of the first control unit is completed, the display module can be powered on and initialized 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, there is no need to wait for the main chip to be initialized before the icon is displayed. Instead, the icon can be displayed before the main chip is initialized (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 time for the independent initialization of the first control unit is shorter, thereby reducing the delay in displaying the icon after powering on, reducing the waiting time and anxiety of the user, avoiding the user from performing redundant power-on operations again, and improving the user experience.
