  In order to clarify technical problems, technical solutions, and advantages to be solved by the present invention, the present invention will be described in detail below with reference to the drawings and specific embodiments.

  As shown in FIG. 1, the time display method according to the embodiment of the present invention includes the following steps.

  In step S101, a time bitmap of the current time is read from the memory, the time bitmap is displayed, and the system is controlled to enter a sleep state. At least a plurality of time bitmaps are stored in the memory, A time bitmap indicates one time, and the plurality of time bitmaps are stored according to a time order.

  In this embodiment, the time bitmap stored in the memory may store a plurality of time bitmaps in the memory before the system goes to sleep, and each time bitmap indicates one time. Thus, the time can be updated without waking up the system when the system sleeps. For example, as shown in FIG. 2, the time 00:00 to 23:59 includes one time bitmap every other minute. Of course, a 12-hour clock may be used in some scenes, but this is not a limitation. These time bitmaps may be binary bitmaps. For example, a 24-hour or 12-hour time series is converted into a binary bitmap and stored in the memory in order. Of course, in some scenes, the time bitmap may be of the dial type, that is, each time bitmap may be a complete dial bitmap showing one time, of course, In order to save memory, the time bitmap may further be a dial hand, i.e. the hand only needs to be updated each time it is updated and the static part of the dial may always change.

  In addition, entering the system to sleep may be understood to mean that the smart watch system does not start, and thus, by saving power consumption of the smart watch, realizing the power saving purpose. Can do.

  In step S102, the time bitmap next to the currently displayed time bitmap is read from the memory at predetermined intervals, and the currently displayed time bitmap is updated to the currently read time bitmap.

  In this embodiment, the time difference shown in any two of the plurality of time bitmaps stored in succession may be the same, for example, one time bitmap every other minute. is there. Further, the predetermined time may be equal to a time difference indicated in any two consecutively stored time bitmaps among the plurality of time bitmaps. For example, step S102 is executed once every minute.

  It should be noted that step S102 is repeatedly executed, that is, the time bitmaps currently displayed at the time of execution are different, and thus the time bitmaps currently read and updated at the time of execution are also different. For example, taking an interval of 1 minute as an example, if the time bitmap currently being displayed is 00:00 when executed for the first time, the time bitmap read first is 00:01, that is, the first time When 00:00 is updated to 00:01 and the time bitmap currently displayed is 00:01, the time bitmap read the second time is 00:02. By updating 00:01 to 00:02 for the second time and executing in this way, the complete time can be displayed. Of course, when the currently displayed time bitmap is the last bitmap stored in the memory, for example 23:59, the first time bitmap, for example 0:00, is read and updated.

  In the present embodiment, the above method may be applied to a smart watch.

  In this embodiment, the time bitmap of the current time is read from the memory, the time bitmap is displayed, and the system is controlled to enter a sleep state. At least a plurality of time bitmaps are stored in the memory. Each time bitmap indicates one time, and the plurality of time bitmaps are stored in time order, and the next time bitmap of the currently displayed time bitmap is read from the memory at predetermined time intervals. Thus, the currently displayed time bitmap is updated to the currently read time bitmap. As described above, by realizing the update and display of the time in the sleep state of the system, the power consumption of the smart watch can be reduced and the battery driving time can be extended.

  As shown in FIG. 3, another time display method according to an embodiment of the present invention includes the following steps.

  In step S301, a time bitmap of the current time is read from the memory, the time bitmap is displayed, and the system is controlled to enter a sleep state. At least a plurality of time bitmaps are stored in the memory, A time bitmap indicates one time, and the plurality of time bitmaps are stored according to a time order.

  In step S302, the next time bitmap of the currently displayed time bitmap is read from the memory based on the current offset amount, where the current offset amount is the currently displayed time bitmap in the memory. And the offset amount of the next time bitmap.

  In this embodiment, since all the time bitmaps are stored in the memory, an offset is generated between the time bitmaps. However, the current offset amount is determined from the time bitmap currently being displayed from the memory and the next time bitmap. Is the offset amount, so the next time bitmap can be read based on the current offset amount.

  For example, when step S302 is executed for the first time and the time bitmap currently being displayed is the time bitmap of the current time in step S302, the current offset amount is the time bitmap of the current time in step S302. And the time bitmap of the next time. For example, if the time bitmap of the current time in step S302 is 0:00, when the step S302 is executed for the first time, the time bitmap of the current offset amount is 00:00 and the time bit of 00:01 Therefore, the time bit map of 00:01 is read based on the offset amount. Further, the current offset amount when step S302 is executed for the first time may be set when step S301 is executed. For example, when the time bitmap of the current time is read in step S301, the current offset amount is set. Thus, the current offset amount can be used when step S302 is executed for the first time.

  In addition, the current offset amount is the offset amount between the time bitmap currently displayed in the memory and the next time bitmap. Thus, the time bitmap currently being displayed is constantly changing. The offset amount of the current time is also constantly changing, and therefore the next time bitmap read is always changing.

  In step S303, the currently displayed time bitmap is updated to the currently read time bitmap, and the current offset amount is updated.

  The time bitmap currently read in step S303 is the time bitmap read in step S302, that is, the time bitmap currently displayed in step S302 is updated to the time bitmap currently read in step S302. For example, the currently displayed time bitmap is 11:11, and 11:12 is read when step S302 is executed, and therefore 11:11 is updated to 11:12 in step S303.

  Since the current offset amount is the offset amount in the memory of the currently displayed time bitmap and the next time bitmap, the currently displayed time bitmap is updated to the currently read time bitmap in step S302. At this time, the currently displayed time bitmap is the updated time bitmap. Therefore, in step S303, the current offset amount is updated to the offset amount between the updated time bitmap and the next time bitmap. For example, when updating 11:11 to 11:12 in step S303, updating the current offset amount in S303 means that the current offset amount is 11:12 and 11:13 in the memory. Therefore, it is ensured that the current offset amount after update is used for reading each time it is read in step S302.

  In step S304, a step of repeatedly reading a time bitmap next to the currently displayed time bitmap from the memory based on the current offset amount is repeatedly triggered every predetermined time.

  The step S302 and the step S303 can be repeatedly executed based on the predetermined time by the step S304. For example, when step S302 is executed for the first time, since the time bitmap currently being displayed is 11:11, 11:12 is read in step S302, 11:11 is updated to 11:12 in step S303, When triggering step S302 after 1 minute, the currently displayed time bitmap is 11:12, so 11:13 is read in step S302 and 11:12 is updated to 11:13 in step S303. When step S302 is triggered after one minute, the currently displayed time bitmap is 11:13, so 11:14 is read in step S302 and 11:13 is updated to 11:14 in step S303. In this way, all the times can be displayed completely.

Preferably, repeatedly triggering the step of reading the next time bitmap of the currently displayed time bitmap from the memory based on the current offset amount at predetermined time intervals,
Each time a predetermined scheduled interrupt occurs, the method may include triggering a step of reading a time bitmap next to a currently displayed time bitmap from the memory based on a current offset amount.

  Here, the predetermined scheduled interrupt may be a preset interrupt every predetermined time. For example, if interrupting once every minute, step S302 can be triggered once every other minute, Of course, every time step S302 is executed, step S303 is executed once.

  In this embodiment, it is not necessary to activate the smart watch system to interrupt the execution of step S302 every predetermined time by interrupting, thereby saving the amount of electricity of the smartphone.

Preferably, in the embodiment, each time a predetermined scheduled interrupt occurs, triggering a step of reading a time bitmap next to a currently displayed time bitmap from the memory based on a current offset amount,
A central processing unit (CPU) for executing a step of reading a time bitmap next to a currently displayed time bitmap from the memory based on a current offset amount each time a predetermined scheduled interrupt occurs. Setting the low power operation mode, setting the display for displaying the memory and the time bitmap to the operation mode, and the time next to the time bitmap currently being displayed from the memory based on the current offset amount Triggering the step of reading the bitmap,
The time display method updates the currently displayed time bitmap to the currently read time bitmap, and when the current offset amount is updated, stops the operation of the CPU, and sets the memory and display to a predetermined value. And setting to the power saving mode.

  In this embodiment, each time a predetermined scheduled interrupt occurs, the CPU can be set to a predetermined low power operation mode, thus saving electricity and the predetermined low power operation mode is It may be set in advance by the user or may be a default smart watch.

  Further, when updating the currently displayed time bitmap to the currently read time bitmap and updating the current offset amount, the operation of the CPU is stopped, and the memory and the display are set to a predetermined power saving mode. In order to further save the amount of electricity for setting, the operation of the CPU may be stopped after the time update is completed, and the amount of electricity is set by setting the memory and the display to a predetermined power saving mode. Can be further saved and the battery life of the smartwatch can be extended. The predetermined power saving mode may be set in advance by the user or may be a smart watch default, for example, a single core / minimum frequency, which is not limited.

Preferably, reading the time bitmap of the current time from the memory and displaying the time bitmap is
Reading a current time time bitmap and background bitmap from memory and overlaying the time bitmap on the background location to display the time bitmap and the background bitmap;
Updating the currently displayed time bitmap to the currently read time bitmap
Updating the currently displayed time bitmap overlaid on the background bitmap to the currently read time bitmap.

  In the embodiment, the time bitmap can be displayed to be overlaid on the background bitmap, and when updating the time, only the time bitmap overlaid on the background bitmap is updated, but the background bitmap The amount of electricity can be saved by reducing the power consumption. An exemplary background bitmap and time bitmap may refer to FIG. 4, which displays the background bitmap in the background area, but displays the time bitmap in the time display area. The background bitmap may be converted from a background image selected in advance by the user into a binary bitmap and stored in a memory.

  In the present embodiment, the above method may be executed when the smart watch is in the always-on mode.

  Of course, in this embodiment, it may be applied to the example shown in FIG. 1 as well, and the same beneficial effects can be realized.

  The interrupt processing module is set to receive an interrupt and notify the CPU to operate.

  The CPU module is set to execute the contents of the update time interrupt service module.

  The update time interrupt service module is in charge of setting the CPU to the power saving operation mode, for example, operates at the single core / lowest frequency, sets the LCD module and the memory module to the operation mode, and stores the time bitmap offset stored. Based on the amount, the time bitmap to be updated is fetched and transmitted to the time display area in the LCD module, the offset amount of the bitmap is updated to the offset amount of the time bitmap to be updated next, and the update time interrupt service After the processing of the module is finished, the CPU module is set to notify the CPU module to stop the operation after the LCD module and the memory are set to the sleep mode.

  The LCD module is configured to receive and display the transmitted time bitmap.

  The sleep module puts the system to sleep and overlays the current time bitmap with the user-selected background bitmap during sleep to generate the first time bitmap during sleep and updates it to the LCD. When the time is updated again during the sleep, the time display area is set to be updated only by transmitting the time bitmap without updating the background bitmap.

  The wakeup module is configured to wake up the system and stop the operation of the update time interrupt service module when receiving a wakeup source.

  The system shown in FIG. 6 is merely an example of an embodiment of the present invention, and some of the modules included in the system may be virtual modules, while the rest are modules that combine virtual and hardware, It may also be a hardware module and should be described as not limiting embodiments of the present invention.

  In step S501, the initial system is in the operation mode.

  In step S502, the user sets the system to the always-on mode, selects a background map during sleep, and selects a time bitmap style during sleep.

  In this step, the smart watch sets the system to the always-on mode in response to the operation input by the user, receives the operation input by the user, selects the background map, receives the operation input by the user, and sleeps. It may be understood that selecting a time bitmap style.

  In step S503, the selected background map and time bitmap sequence is converted into a binary bitmap and stored in the memory.

  This step may be realized by a bitmap module.

  In step S504, when the system goes to sleep, if it is currently in the always on mode, the back light is set to always on, the corresponding time bitmap is overlaid on the background bitmap based on the current time, and the generated bitmap Is updated on the screen, the offset amount of the time bitmap to be updated next time is recorded, and finally the system goes to sleep.

  The screen may be an LCD display. The offset amount of the time bitmap to be updated next time is understood to be the offset amount in the memory of the currently displayed time bitmap and the next time bitmap, that is, the current offset amount described in the above embodiment. May be.

  In step S505, when a scheduled interrupt occurs, the CPU starts to operate.

  In this step, the CPU may execute the update time interrupt service module when the CPU starts to operate.

  In step S506, by setting the CPU to the low power operation mode, the memory and the LCD are set to the operation mode, and the time bitmap is extracted based on the offset amount of the time bitmap to be updated at present and updated in the time display area. The offset amount of the time bitmap to be updated next time is updated.

  This step may be realized by an update time interrupt service module.

  In step S507, after the time update is completed, the memory and LCD are set to the power saving mode, and the CPU is notified to stop the operation.

  This step may be realized by an update time interrupt service module.

  In step S508, a new scheduled interrupt occurs.

  The step does not wake up the system, only updates the time, and the system is still in the sleep state.

  In step S509, when receiving an interrupt to wake up the system, the operation of the update time interrupt service module is stopped. Wake up the system and the system is in full operating mode.

  When execution of the step is complete, the user can operate the system.

  Within the dotted line shown in FIG. 5, it should be described that the smartwatch system is always in the sleep state.
