[0002] The central processing unit (CPU) is the main processor in an electronic device. The CPU in the electronic device and the system executed thereon will enter a power saving mode after being idle for a period of time (for example, the CPU is powered off and the system enters a sleep mode). One of the ways to leave the power saving mode is to wake up (or restore) the CPU and the system through a wake-up signal. After waking up the CPU and the system, the CPU and the system update system data and control the display device in the electronic device to display specific content. Waking up the CPU and the system to control the display device in the electronic device to display specific content will increase power consumption. Therefore, how to improve the power consumption of the electronic device is an important problem to be solved. Summary of the invention

In some examples, the modem 1000, the WLAN processor 1010, and the storage device 1060 may be located outside the SoC where the CPU 1110 and the microprocessor 1120 are located.

[0018] Please combine Figure 1 See also Figure 2 . Figure 2 2 is a flow chart of a process 20 according to one embodiment of the present disclosure. In step 202, the sensor 1100 senses the angle change of the electronic device 10 and generates an angle change signal (or receives the angle change signal), and transmits (or sends) the angle change signal to the microprocessor 1120. The angle change signal indicates the angle change of the electronic device 10. In step 204, the microprocessor 1120 receives the angle change signal from the sensor 1100 and processes the angle change signal (e.g., through an external interrupt (EINT) function). In one embodiment, if the microprocessor 1120 is in a sleep state (e.g., the microprocessor 1120 is powered off or in a sleep mode), the angle change signal wakes up the microprocessor 1120. Then, the microprocessor 1120 processes the angle change signal. In one embodiment, if the microprocessor 1120 is in an awake state (e.g., the microprocessor 1120 is in an active mode or an idle mode), the microprocessor 1120 directly receives and processes the angle change signal.

[0019] In step 206, the microprocessor 1120 transmits (or outputs) the wake-up information (e.g., the wake-up interface) to the storage device 1060. In some examples, in step 206, if the storage device 1060 is not powered on, the microprocessor 1120 will first power on the storage device 1060 before transmitting (or outputting) the wake-up information (e.g., the wake-up interface) to the storage device 1060. The wake-up information corresponds to the angle change signal, and the wake-up information is the content to be displayed on the display device 1050. In step 208, the microprocessor 1120 (e.g., the display driver in the microprocessor 1120) turns on the power of the display device 1050 and controls the display controller 1040 to adjust the backlight of the display device 1050. In step 210, the microprocessor 1120 sets the output frame rate and / or the screen refresh rate through the display controller 1040 to obtain better power consumption and better display effect. In step 212, the microprocessor 1120 controls the display controller 1040 to obtain (or retrieve) the wake-up information from the storage device 1060. In step 214, the display controller 1040 transmits (or outputs) the wake-up information to the display device 1050 according to the wake-up function. In step 216, the display device 1050 receives the wake-up information from the display controller 1040 and displays the wake-up information. In step 218, the microprocessor 1120 turns off the power of the display controller 1040 and the storage device 1060 after the display device 1050 displays the wake-up information.

[0020] It should be noted that Figure 2 Some of the steps in step 206 may be skipped. In one embodiment, if the display device 1050 is already powered on, step 208 may be skipped. In another embodiment, the transmission operation in step 206 is only used to notify the storage device 1060 that the wake-up function has been activated. The adjustment in step 208 and / or step 210 may be skipped. In one embodiment, step 218 may be skipped.

[0021] There are many variations of process 20. In one embodiment, in step 206, the microprocessor 1120 transmits the wake-up information to the storage device 1060 and the display device 1050. If the storage device 1060 and the display device 1050 are powered off, the microprocessor 1120 will first power on the storage device 1060 and the display device 1050 before transmitting the wake-up information. If the storage device 1060 and the display device 1050 are powered on, the microprocessor 1120 will transmit the wake-up information to the storage device 1060 and / or the display device 1050 to notify that the wake-up function has been activated.

[0022] In some examples, in process 20, CPU 1110 is powered off, and the system executed on CPU 1110 is in sleep mode, and display device 1050 is powered off. In other examples, in process 20, CPU 1110 is powered on.

[0023] Please combine Figure 1 See also Figure 3 . Figure 3 30 is a flow chart of process 30 according to one embodiment of the present disclosure. In step 302, modem 1000 receives network data including a missed call signal and transmits (or sends) the network data to microprocessor 1120. The missed call signal indicates a missed call of electronic device 10. In step 304, microprocessor 1120 receives network data from modem 1000 and processes the missed call signal (e.g., through EINT function). In one embodiment, if microprocessor 1120 is in a sleep state (e.g., microprocessor 1120 is powered off or in sleep mode), network data or missed call signal wakes up microprocessor 1120. Then, microprocessor 1120 processes network data. In one embodiment, if microprocessor 1120 is in an awake state (e.g., microprocessor 1120 is in active mode or idle mode), microprocessor 1120 directly receives and processes network data.

[0024] In step 306, the microprocessor 1120 transmits (or outputs) the missed call reminder information to the storage device 1060. In some examples, in step 306, if the storage device 1060 is not powered on, the microprocessor 1120 will first power on the storage device 1060 before transmitting (or outputting) the missed call reminder information to the storage device 1060. The missed call reminder information corresponds to the missed call signal. In step 308, the microprocessor 1120 (e.g., a display driver in the microprocessor 1120) turns on the power of the display device 1050 and controls the display controller 1040 to adjust the backlight of the display device 1050. In step 310, the microprocessor 1120 sets the output frame rate and / or screen refresh rate through the display controller 1040 to obtain better power consumption and better display effect. In step 312, the microprocessor 1120 controls the display controller 1040 to obtain (or retrieve) the missed call reminder information from the storage device 1060. In step 314, the display controller 1040 transmits (or outputs) the missed call reminder information to the display device 1050 according to the missed call display function. In step 316, the display device 1050 receives the missed call reminder information from the display controller 1040 and displays the missed call reminder information. In step 318, the microprocessor 1120 turns off the power of the display controller 1040 and the storage device 1060 after the display device 1050 displays the missed call reminder information.

[0025] It should be noted that Figure 3 Some of the steps in step 306 can be skipped. In one embodiment, if the display device 1050 is already turned on, step 308 can be skipped. In another embodiment, the transmission operation in step 306 is only used to notify the storage device 1060 that the missed call display function has been activated. The adjustment in step 308 and / or step 310 can be skipped. In one embodiment, step 318 can be skipped.

[0026] There are many variations of process 30. In one embodiment, in step 306, the microprocessor 1120 transmits the missed call reminder information to the storage device 1060 and the display device 1050. If the storage device 1060 and the display device 1050 are in a power-off state, the microprocessor 1120 will turn on the power of the storage device 1060 and the display device 1050 before transmitting the missed call reminder information. If the storage device 1060 and the display device 1050 are in a power-on state, the microprocessor 1120 will directly transmit the missed call reminder information to the storage device 1060 and / or the display device 1050 to notify that the missed call display function has been activated.

[0027] In some examples, in process 30, CPU 1110 is in a power-off state, and the system executed on CPU 1110 is in a sleep mode, and display device 1050 is in a power-off state. In other examples, in process 30, CPU 1110 is in a power-on state.

[0028] Please combine Figure 1 See also Figure 4 . Figure 4 4 is a flow chart of process 40 according to one embodiment of the present disclosure. In step 402, the touch device 1090 senses a double click (or receives a double click signal) and transmits (or sends) the double click signal to the microprocessor 1120. The double click signal represents a command input by the user (e.g., turning on the display device 1050). In step 404, the microprocessor 1120 receives the double click signal from the touch device 1090 and processes the double click signal (e.g., through the EINT function). In one embodiment, if the microprocessor 1120 is in a sleep state (e.g., the microprocessor 1120 is in a power off or sleep mode), the double click signal wakes up the microprocessor 1120. Then, the microprocessor 1120 processes the double click signal. In one embodiment, if the microprocessor 1120 is in an awake state (e.g., the microprocessor 1120 is in an active mode or an idle mode), the microprocessor 1120 directly receives and processes the double click signal.

[0029] In step 406, the microprocessor 1120 transmits (or outputs) the wake-up information (e.g., the wake-up interface) to the storage device 1060. In some examples, in step 406, if the storage device 1060 is not turned on, the microprocessor 1120 turns on the power of the storage device 1060 before transmitting (or outputting) the wake-up information to the storage device 1060. The wake-up information corresponds to a double-click signal. In step 408, the microprocessor 1120 (e.g., the display driver in the microprocessor 1120) turns on the power of the display device 1050 and controls the display controller 1040 to adjust the backlight of the display device 1050. In step 410, the microprocessor 1120 sets the output frame rate and / or screen refresh rate through the display controller 1040 to obtain better power consumption and display effect. In step 412, the microprocessor 1120 controls the display controller 1040 to obtain (or retrieve) the wake-up information from the storage device 1060. In step 414, the display controller 1040 transmits (or outputs) the wake-up information to the display device 1050 according to the double-click screen start function. In step 416, the display device 1050 receives the wake-up information from the display controller 1040 and displays the wake-up information. In step 418, after the display device 1050 displays the wake-up information, the microprocessor 1120 turns off the power of the display controller 1040 and the storage device 1060.

[0030] It should be noted that Figure 4 Some of the steps in step 406 can be skipped. In one embodiment, if the display device 1050 is already powered on, step 408 can be skipped. In another embodiment, the transmission operation in step 406 is only used to notify the storage device 1060 that the double-click screen power-on function has been activated. The adjustment in step 408 and / or step 410 can be skipped. In one embodiment, step 418 can be skipped.

[0031] There are many variations of process 40. In one embodiment, in step 406, the microprocessor 1120 transmits the wake-up information to the storage device 1060 and the display device 1050. If the storage device 1060 and the display device 1050 are in a power-off state, the microprocessor 1120 turns on the power of the storage device 1060 and the display device 1050 before transmitting the wake-up information. If the storage device 1060 and the display device 1050 are in a power-on state, the microprocessor 1120 directly transmits the wake-up information to the storage device 1060 and / or the display device 1050 to notify that the double-click screen turn-on function has been activated.

[0032] In some examples, in process 40, CPU 1110 is in a power-off state, and the system executed on CPU 1110 is in a sleep mode, and display device 1050 is in a power-off state. In other examples, in process 40, CPU 1110 is in a power-on state.

[0033] Please combine Figure 1 See also Figure 5A and Figure 5B . Figure 5A and Figure 5B is a flowchart 50 according to an embodiment of the present disclosure. In process 50, the CPU 1110 is turned on (i.e., powered on), and the system executed on the CPU 1110 is in active mode, and the display device 1050 is turned on (i.e., powered on). In step 502, when the system is in an awake state (e.g., in active mode or idle mode), the Always On Display function is turned on (e.g., turned on by the user). In step 504, if the system is in idle mode for a predetermined time, the system prepares to enter sleep mode from idle mode. In step 506, the CPU 1110 notifies the microprocessor 1120 that the Always On Display function is enabled and sends an Always On Display notification signal. That is, the Always On Display notification signal indicates that the Always On Display function is enabled. In step 508, the microprocessor 1120 receives the Always On Display notification signal from the CPU 1110 and processes the Always On Display notification signal (e.g., through the EINT function). In one embodiment, if the microprocessor 1120 is in a sleep state (e.g., the microprocessor 1120 is powered off or in a sleep mode), the always-on notification signal wakes up the microprocessor 1120. The microprocessor 1120 then processes the always-on notification signal. In one embodiment, if the microprocessor 1120 is in an awake state (e.g., the microprocessor 1120 is in an active mode or an idle mode), the microprocessor 1120 directly receives and processes the always-on notification signal.

[0034] In step 510, after the microprocessor 1120 receives the always-on display notification signal, the CPU 1110 enters a power-off state and the system enters a sleep mode. However, the display device 1050 is not in a power-off state, that is, the power of the display device 1050 is not turned off. In step 512, after processing the always-on display notification signal, the microprocessor 1120 transmits the always-on display information (e.g., the always-on display interface) to the storage device 1060. In some examples, in step 512, if the storage device 1060 is not in a power-on state, the microprocessor 1120 turns on the power of the storage device 1060 before transmitting the always-on display information to the storage device 1060. The always-on display information corresponds to the always-on display notification signal. In step 514, the microprocessor 1120 (e.g., a display driver in the microprocessor 1120) turns on the display controller 1040 and controls the display controller 1040 to adjust the backlight of the display device 1050. In step 516, the microprocessor 1120 sets the output frame rate and / or screen refresh rate through the display controller 1040 to obtain better power consumption and display effect. In step 518, the microprocessor 1120 controls the display controller 1040 to obtain (or retrieve) the always-on display information from the storage device 1060. In step 520, the display controller 1040 transmits (or outputs) the always-on display information to the display device 1050 according to the always-on display function.

[0035] In step 522, the display device 1050 receives the always-on display information from the display controller 1040 and displays the always-on display information. In step 524, after the display device 1050 displays the always-on display information, the microprocessor 1120 turns off the power to the display controller 1040 and the storage device 1060. In step 526, a timer is set to transmit (or send) an always-on display notification signal to the microprocessor 1120 periodically (e.g., every minute). The method repeats steps 526, 512, 514, 516, 518, 520, 522, 524 until the timer is turned off to exit the always-on display function, when the system is awakened, or until the timer has transmitted (or sent) a predetermined number of always-on display notification signals. In some examples, the microprocessor 1120 can turn off the timer at any time when needed.

[0036] It should be noted that Figure 5A and Figure 5B Some of the steps in can be skipped. In one embodiment, if the power of the display device 1050 is turned on, step 514 can be skipped. The adjustment in step 514 and / or step 516 can be skipped. In one embodiment, step 524 can be skipped.

[0037] There are many variations of process 50. In one embodiment, in step 512, the microprocessor 1120 transmits the always-on display information to the storage device 1060 and the display device 1050. If the storage device 1060 and the display device 1050 are already in a power-off state, the microprocessor 1120 first turns on the power of the storage device 1060 and the display device 1050 before transmitting the always-on display information to the storage device 1060 and the display device 1050. If the storage device 1060 and the display device 1050 are already in a power-on state, the microprocessor 1120 directly transmits the always-on display information to the storage device 1060 and / or the display device 1050.

[0038] The operation of the microprocessor 1120 in the above description can be summarized as a process 60 of the electronic device 10, such as Figure 6 Process 60 includes the following steps:

[0039] Step 602: Receive a display trigger signal.

[0040] Step 604: Control a display device (eg, display device 1050 ) in the electronic device to display content in response to a display trigger signal.

[0041] In some examples, in process 60, when the microprocessor 1120 controls the display device 1050 to display content, the CPU 1110 is in a power-off state (or has been powered off). That is, in certain situations (e.g., lift to wake up, missed call display function, double-click screen wake up, or always display), the microprocessor 1120, rather than the CPU 1110, controls the display device 1050 to display content.

[0042] The implementation of process 60 is not limited to the above description. The following examples can be applied to implement process 60.

[0043] In one embodiment, when the display device 1050 is in the power-off state, the CPU 1110 is already in the power-off state, and the system executed on the CPU 1110 is in the sleep mode. In one embodiment, when the display device 1050 is powered on, the CPU 1110 is already powered on, and the system executed on the CPU 1110 is in the active mode. In one embodiment, when the microprocessor 1120 receives the display trigger signal, the CPU 1110 is in the power-off state. In one embodiment, after the microprocessor 1120 receives the display trigger signal, the CPU 1110 enters the power-off state.

[0044] In one embodiment, the display trigger signal includes (for example, is) an angle change signal received from the sensor 1100, and the displayed content includes (for example, is) wake-up information (for example, a wake-up interface). In one embodiment, the angle change signal indicates an angle change of the electronic device 10. In one embodiment, the display trigger signal includes (for example, is) a missed call signal received from the modem 1000, and the displayed content includes (for example, is) a missed call reminder message. In one embodiment, the missed call signal indicates a missed call of the electronic device 10. In one embodiment, the display trigger signal includes (for example, is) a double-click signal received from the touch device 1090, and the displayed content includes (for example, is) wake-up information (for example, a wake-up interface). In one embodiment, the double-click signal indicates a command input by the user (for example, turning on the display device 1050). In one embodiment, the display trigger signal includes (for example, is) an always-displayed notification signal received from the CPU 1110 or a timer, and the displayed content includes (for example, is) always-displayed information (for example, always-displayed interface). In one embodiment, the always-displayed notification signal indicates that the always-displayed function is enabled.

[0045] In one embodiment, the display trigger signal is processed by the microprocessor 1120 through the EINT function. In one embodiment, the EINT function enables an interrupt after two or more cycles (e.g., a master clock (MCLK) cycle) outside the current master clock (MCLK). In one embodiment, the displayed content corresponds to the display trigger signal. In one embodiment, the displayed content includes at least one image or at least one picture. In one embodiment, if the microprocessor 1120 is in a sleep state, the display trigger signal wakes up the microprocessor 1120. Then, the microprocessor 1120 processes the display trigger signal. In one embodiment, if the microprocessor 1120 is in an awake state, the microprocessor 1120 directly receives and processes the display trigger signal.

[0046] In one embodiment, when the microprocessor 1120 controls the display device 1050 to display content, the microprocessor 1120 controls the display controller 1040 to adjust the backlight of the display device 1050. In one embodiment, when the microprocessor 1120 controls the display device 1050 to display content, the microprocessor 1120 sets the output frame rate and the screen refresh rate through the display controller 1040. In one embodiment, the output frame rate is the rate (or frequency) at which continuous images (or continuous frames) are captured or displayed. In one embodiment, the screen refresh rate is the rate (e.g., the number of times per second) at which an image is refreshed on the screen of the electronic device 10. In one embodiment, the microprocessor 1120 is a low-power microprocessor (e.g., MIPS, RISC, or DSP). In one embodiment, the microprocessor 1120 and the CPU 1110 are located in the same system chip (SOC).

[0047] In one embodiment, the steps of the microprocessor 1120 controlling the display device 1050 to display content include: the microprocessor 1120 transfers the content to the storage device 1060; the microprocessor 1120 controls the display controller 1040 to obtain the content from the storage device 1060; the display device 1050 receives the content from the display controller 1040 and displays the content; after the display device 1050 displays the content, the microprocessor 1120 turns off the power of the display controller 1040 and the storage device 1060.

[0048] In one embodiment, the steps of the microprocessor 1120 controlling the display device 1050 to display content include: the microprocessor 1120 transmits the content to the storage device 1060; the microprocessor 1120 turns on the power of the display controller 1040, and controls the display controller 1040 to obtain content from the storage device 1060; the display controller 1040 transmits the always-on display information to the display device 1050 according to the function; the display device 1050 receives the content from the display controller 1040, and displays the content; after the display device 1050 displays the content, the microprocessor 1120 turns off the power of the display controller 1040 and the storage device 1060.

[0049] In conclusion, the embodiments of the present disclosure provide a method and an electronic device for processing display control. In a specific scenario, a microprocessor rather than a CPU (and a system executed by the microprocessor) controls the display content of a display device. When the microprocessor controls the display device, the CPU is in a power-off state and the system is in a sleep mode. Therefore, power consumption can be improved.
