detailed description

The technical problems, the technical solutions, and the advantages of the present invention will be more clearly described in the following description.

As shown in FIG. 1 , an embodiment of the present invention provides a time display method, including the following steps:

Step S101: Read a time bitmap of the current time from the memory, display the time bitmap, and control the system to enter hibernation, wherein at least a plurality of time bitmaps are stored in the memory, and each time bitmap represents one Time, and the plurality of time bitmaps are stored in chronological order.

In this embodiment, the time bitmap stored in the memory may be that the system stores multiple time bitmaps in the memory before entering the sleep, and each time bitmap represents a time, so that the system does not wake up when the system sleeps. It is possible to update the time. For example, as shown in FIG. 2, a time bitmap is included every one minute from 00:00 to 23:59. Of course, in some scenarios, a 12-time system can also be used, which is not limited thereto. These time bitmaps can be binary bitmaps, for example, converting a 24-hour or 12-hour time series into a binary bitmap and storing them in memory in order. Certainly, in some scenarios, the time bitmap may also be in a dial format, that is, each time bitmap may be a bitmap indicating a complete dial of a time. Of course, in order to save memory, the time bitmap may also be a dial. The hands of the hands, that is, only need to update the hands every time the update, and the static part of the dial can always change.

In addition, the above system enters sleep can be understood as the system of the smart watch does not start, which can save the power consumption of the smart watch to achieve the purpose of power saving.

Step S102: Read the next time bitmap of the time bitmap currently displayed in the memory every preset time, and refresh the currently displayed time bitmap to the currently read time bitmap.

In this embodiment, the time difference represented by any two consecutively stored time bitmaps in the plurality of time bitmaps may be the same, for example, one time bitmap every one minute. In addition, the preset time may be equal to the difference between the times represented by any two consecutively stored time bitmaps in the plurality of time bitmaps. For example, step S102 is performed once every minute.

It should be noted that since the step S102 is executed cyclically, that is, the time bitmap currently displayed at each execution is different, so that the time bitmap of the current read and refresh at each execution can be different. For example, taking a one-minute interval as an example, when the first time execution, the currently displayed time bitmap is 00:00, then the time bitmap for the first reading is 00:01, that is, the first time will be 00:00. Refreshed to 00:01; the second time execution, the currently displayed time bitmap is 00:01, Then, the time bitmap of the second read is 00:02, that is, the second time 00:01 is refreshed to 00:02, and this is always performed, so that the complete time can be displayed. Of course, if the currently displayed time bitmap is the last bitmap stored in memory, for example: 23:59, then the first time bitmap is read, for example: 00:00, and refreshed.

In this embodiment, the above method can 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 control system enters hibernation, wherein at least a plurality of time bitmaps are stored in the memory, and each time bitmap is stored. Representing a time, and the plurality of time bitmaps are stored in chronological order; every other preset time, reading a next time bitmap of the currently displayed time bitmap in the memory, and displaying the currently displayed time bit The graph is refreshed as the time bitmap of the current read. In this way, the system can update and display the time in the sleep state, so as to reduce the power consumption of the smart watch and prolong the battery life.

As shown in FIG. 3, an embodiment of the present invention provides another time display method, including the following steps:

Step S301: Read a time bitmap of the current time from the memory, display the time bitmap, and control the system to enter hibernation, wherein at least a plurality of time bitmaps are stored in the memory, and each time bitmap represents one Time, and the plurality of time bitmaps are stored in chronological order.

Step S302: Read a next time bitmap of the time bitmap currently displayed in the memory according to the current offset, where the current offset is the currently displayed time bitmap and the next time bitmap in the memory. The offset in .

In this embodiment, since the time bitmaps are all in the memory, the offsets are stored between the time bitmaps, and the current offset is the offset between the currently displayed time bitmap and the next time bitmap in the memory. Thereby the next time bitmap can be read based on the current offset.

For example, when the step S302 is executed for the first time, then the currently displayed time bitmap is the time bitmap of the current time in step S302, then the current offset at this time is the current time in step S302. The offset of the time bitmap from the time bitmap of the next time. For example, the time bitmap of the current time in step S302 is 00:00, then, in the first execution of step S302, the current offset is a time bitmap of 00:00 and a time bitmap of 00:01. Offset, thereby reading the time bitmap of 00:01 based on the offset. In addition, in step S302 The current offset at the time of the first execution may be set when the step S301 is executed. For example, when the time bitmap of the current time is read in step S301, the current offset is set, so that step S302 is at the first This current offset can be used when it is executed.

In addition, the current offset is the offset between the time bitmap currently displayed in the memory and the next time bitmap, such that as the currently displayed time bitmap is constantly changing, the current offset is also constantly changing, such that The next time bitmap that can be read is also constantly changing.

Step S303: Refresh the currently displayed time bitmap to the currently read time bitmap, and update the current offset.

The time bitmap currently read in step S303 is the time bitmap read in step S302. That is, step S302 refreshes the currently displayed time bitmap 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 performed, so that step S303 refreshes 11:11 to 11:12.

In addition, since the current offset is the offset of the currently displayed time bitmap and the next time bitmap in the memory, the currently displayed time bitmap is refreshed to the currently read time bitmap in step S302. Then, the time bitmap currently displayed at this time is the refreshed time bitmap, so that the current offset is updated in step S303 to be the offset of the refreshed time bitmap and the next time bitmap. For example, in step S303, 11:11 is refreshed to 11:12. Then, S303 updates the current offset to use the offset in memory of 11:12 and 11:13 as the current offset, thereby ensuring that step S302 is read each time. The time is read using the updated current offset.

Step S304, the step of periodically reading the next time bitmap of the time bitmap currently displayed in the memory according to the current offset is triggered cyclically every preset time.

The above step S302 and step S303 can be executed in a loop according to the above preset time by step S304. For example, when the first execution of step S302 is performed, the currently displayed time bitmap is 11:11, so step S302 reads 11:12, step S303 refreshes 11:11 to 11:12; after 1 minute interval, the trigger step is repeated. S302, the time bitmap currently displayed at this time is 11:12, so that step S302 reads 11:13, step S303 refreshes 11:12 to 11:13; after 1 minute interval, step S302 is triggered again. The currently displayed time bitmap is 11:13, so step S302 reads 11:14, Step S303 refreshes 11:13 to 11:14, which is continuously executed, so that a complete display of all time can be achieved.

Optionally, the step of periodically triggering the next time bitmap of the time bitmap currently displayed in the memory according to the current offset is triggered by the preset time period, which may include:

The step of reading the next time bitmap of the time bitmap currently displayed in the memory according to the current offset is triggered every time the preset timing interrupt is interrupted.

The preset timing interrupt may be interrupted every preset time set in advance. For example, the interrupt is performed every 1 minute, that is, the step S302 may be triggered every 1 minute. Of course, the step S302 is performed every time. Step S303 is performed once.

In this embodiment, the execution of step S302 is triggered every predetermined time by interrupting, so that the system of the smart watch does not need to be opened to save the power of the smart phone.

Optionally, in the embodiment, the step of triggering the next time bitmap of the time bitmap currently displayed in the memory according to the current offset when the preset timing interrupt is interrupted may include:

Setting the CPU for performing the step of reading the next time bitmap of the time bitmap currently displayed in the memory according to the current offset to a preset low power operation when the preset timing interrupt is interrupted once a mode, and setting the memory and the display screen for representing the time bitmap to an operational mode, and triggering the step of reading the next time bitmap of the time bitmap currently displayed in the memory according to the current offset ;

The method further includes:

When the currently displayed time bitmap is refreshed to the currently read time bitmap and the current offset is updated, the CPU is stopped, and the memory and display are set to the preset power saving mode.

In this implementation manner, the preset timing interrupt can be set to set the CPU to a preset low-power working mode every time the interrupt is interrupted, so that the power can be saved, wherein the preset low-power working mode can be preset by the user, or Smart watches default and so on.

In addition, since the currently displayed time bitmap is refreshed to the current read time bitmap, and When the current offset is updated, the CPU is stopped, and the memory and the display screen are set to a preset power saving mode, so that when the time refresh is completed, the CPU is stopped to further save power. And setting the memory and display screen to the preset power saving mode can further save power and extend the battery life of the smart watch. The preset power saving mode may be preset by the user, or the default of the smart watch, such as a single core minimum frequency, which is not limited thereto.

Optionally, the foregoing time bitmap for reading the current time from the memory, and displaying the time bitmap, may include:

Reading a time bitmap and a background bitmap of the current time from the memory, and displaying the time bitmap and the background bitmap in a manner that the time bitmap is superimposed on the background position;

The refreshing the currently displayed time bitmap to the current read time bitmap includes:

The currently displayed time bitmap superimposed on the background bitmap is refreshed to the currently read time bitmap.

In this implementation manner, the time bitmap overlay can be displayed on the background bitmap, and at the refresh time, only the time bitmap superimposed on the background bitmap is refreshed, and the background bitmap is always maintained, thereby reducing power consumption. Thereby saving electricity. For the illustration of the background bitmap and the time bitmap, as shown in FIG. 4, the background bitmap is displayed in the background area, and the time bitmap is displayed in the time display area. In addition, the background bitmap may be a binary bitmap that converts a background image pre-selected by the user and stored in the memory.

In addition, in this embodiment, the above method may be performed by the smart watch in the constant light mode.

Of course, in this embodiment, the same can be applied to the embodiment shown in FIG. 1 and the same advantageous effects can be achieved.

In this embodiment, a plurality of optional implementation manners are added on the basis of the method shown in FIG. 1, which can reduce the power consumption of the smart watch and prolong the battery life.

The CPU module is set to execute the refresh time interrupt service module content.

The refresh time interrupt service module is set to be responsible for setting the CPU to the power-saving working mode, such as working at the lowest frequency of the single core, and setting the LCD module and the memory module to the working mode, and according to the saved time bitmap offset, the current refresh is required. The time bitmap is sent to the time display area on the LCD module and the bitmap offset is updated to the next time bitmap offset to be refreshed. After the refresh time interrupt service module is processed, after the LCD module and the memory are in the sleep mode, the CPU module is notified to stop working.

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

The hibernation module is set to put the system into hibernation, and superimposes the current time bitmap and the background bitmap selected by the user in the process of hibernation to generate the first time bitmap when sleeping, and refreshes to the LCD. When the system refreshes the time during the sleep process, the background bitmap is no longer refreshed, and only the time bitmap is sent to update the time display area.

The wake-up module is set to wake up the system when the wake-up source is received, and stop the refresh time interrupt service module.

It should be noted that the system shown in FIG. 6 is only an example in the embodiment of the present invention. Some modules included in the system may be virtual modules, and other modules that can be combined with hardware or hardware modules. The embodiment of the present invention is not limited thereto.

Step S503, converting the sequence of the selected background image and the time bitmap into a binary bitmap and storing the data in the memory.

Wherein, the step can be implemented by a bitmap module.

Step S504: When the system enters sleep mode, if the current is in the constant light mode, the backlight is set to be always bright, and according to the current time, the corresponding time bitmap is overlaid on the background bitmap, and the generated bitmap is refreshed to the screen. And record the time bitmap offset to be refreshed next time, the system finally goes to sleep.

Wherein, the above screen may be an LCD screen. In addition, the offset of the time bitmap to be refreshed next time can be understood as the offset of the currently displayed time bitmap and the next time bitmap in the memory, that is, the current offset introduced in the above embodiment.

In step S505, the timer interrupt generates an interrupt, and the CPU starts to work.

In this step, when the CPU starts working, the CPU can execute the refresh time interrupt service module.
