Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
For convenience of understanding, the technical scheme and the technical effect of the invention are described by taking the smart watch as an example. The smart watch of the present invention can enter two modes: one is a normal mode and the other is an ultra-low power display mode. Each of which is described in detail below.
In order to achieve the purpose of the invention, the liquid crystal display screen used by the intelligent watch selects the liquid crystal screen in the semi-reflecting and semi-transmitting mode, so that the dial plate of the screen or other contents can still be clearly shown under the conditions that the backlight is turned off and the system is in a dormant state, and a user can obtain good use experience. In contrast, the watch before the invention has a black screen dial in the dormant state and no information is displayed. In addition, the dial displayed in the ultra-low power consumption state is highly similar to the dial displayed in the normally-on state, and when the dial in the normally-on state is switched to the normally-displayed information state with ultra-low power consumption, the dials are highly similar, so that the switching is not sharp, and the transition is smooth.
Of course, the liquid crystal display screen of the invention does not use the liquid crystal screen in the transflective mode, but can also adopt a common display screen. But a normal display screen cannot display content with the screen backlight turned off. If the display screen is a common display screen, in the idle mode, the backlight brightness cannot be completely closed, and only lower brightness can be set.
FIG. 1 is a normal mode shutdown flow chart of the present invention. The normal _ off of the watch screen is the state that the screen does not display the content, and the main flow is as follows: firstly, turning off the backlight brightness; then the LCD panel is closed and power is supplied; closing MIPI DSI (MIPI (Mobile Industry Processor Interface) is an abbreviation of Mobile Industry Processor Interface, and is an open standard which is initiated by MIPI alliance and established for a Mobile application Processor, DSI (display Pixel Interface) is a serial display Interface protocol which accords with MIPI protocol, and a host is connected with a display by a differential signal line); turning off the LCD controller; the LCD related clock is turned off. Of course, when the screen is closed to the normal mode, the CPU still continues to operate, but the dial does not have any brightness due to the closing of the LCD, so that the information display cannot be seen clearly.
Fig. 2 is a flowchart of the normal mode activation of the present invention. The normal _ on of the watch screen is the normal display state of the screen, and the main flow is as follows: enable and configure MIPI DSI; enabling power supply and initialization of the LCD panel; enabling the LCD controller; enabling an LCD related clock; an appropriate backlight brightness is set. Of course, when the screen displays normally, due to the opening of the backlight brightness, the brightness of the whole watch dial can be far larger than that in the state when the normal mode is not opened. At this time, the information display is also in the clearest state.
The information may be time, or other application data, such as weather, remaining battery power, etc.
Fig. 3 is a flowchart of a method for implementing low-power-consumption normally-displayed information according to the present invention. The method is used for a terminal with a liquid crystal display screen, and the terminal is an intelligent watch or a wireless POS machine.
The method comprises the following steps:
s110, switching the liquid crystal display screen to an idle mode, and adjusting the display power consumption to an ultra-low power consumption display state;
in order to reduce power consumption, the liquid crystal display screen of the screen is switched to an IDLE mode (IDLE mode), and meanwhile, the display power consumption is adjusted to an ultra-low power consumption display state (MIPI enters an ULPS mode). At this point, the backlight brightness is turned off or set low, and the CPU frequency is set lower. Finally, the system enters a sleep state. As shown in fig. 4.
And S120, displaying the acquired terminal dial information in an ultra-low power consumption display state. Because the liquid crystal display screen controller does not have dormancy, consequently liquid crystal display screen can normally show, and liquid crystal display screen selects the liquid crystal display screen of half anti-semi-permeable mode simultaneously, consequently the liquid crystal display screen is closing under the circumstances of backlight and system dormancy, still can clearly show the dial plate of screen, or other content to make the user obtain good use and experience. In contrast, the watch before the invention has a black screen dial in the dormant state and no information is displayed. In addition, the dial displayed in the ultra-low power consumption state is highly similar to the dial displayed in the normally-on state, and when the dial in the normally-on state is switched to the normally-displayed information state with ultra-low power consumption, the dials are highly similar, so that the switching is not sharp, and the transition is smooth.
And S130, periodically starting real-time clock interrupt, and exiting the ultra-low power consumption mode by the processor interface of the mobile industry. Every fixed period (e.g., 1 minute), a Real Time Clock (RTC) interrupt is initiated and the MIPI exits ULPS mode.
And S140, refreshing information display by the dial plate application. The system enters the Ambient mode and the dial application refreshes the display of information once, which may be, for example, 3-5 seconds. And then the MIPI enters the ULPS mode again, and the cyclic display is carried out in such a way, so that the aim of regularly updating dial information display is fulfilled. Here, the real time clock is provided by the CPU.
The refreshing mechanism is based on the standard Android version 5.0 and depends on the Android Dream service. This is also an important innovation of the present invention. The basic concept, flow and advantages of the refresh mechanism are described below:
the basic concept is as follows:
dream mode (screensaver mode): the dream mode is a new characteristic of Android 4.2. This feature can be viewed as an interactive screen saver that can display specific pictures, subscribed news, or other content while the device is idle or locked.
AmbientConfig (configuration control): configuration items for managing the Ambient mode, such as switches, refresh frequency, screen brightness limit, network access limit, JobScheduler limit, wake locks limit.
AmbientService (service control): the management system is a core service for managing the Ambient mode and is used for managing the life cycle of the Ambient mode and accessing the Ambient activity list.
Ambientdraw (ambient mode interface control): the Dream mode interface is realized for monitoring the Dream life cycle change, but does not perform UI rendering operation per se, and can be understood as a transparent Dream, and the start and stop of the Dream are used as signals for opening and closing the active mode.
AmbientActivity: the sleep UI implements an interface, such as a dial or some page that requires special display in the Ambient mode.
AmbientNative (local control): for notifying the kernel to enter or exit the Ambient mode.
The invention is a realization scheme taking AmbientDraam as Draam service, the AmbientDraam is taken as the default Draam service realization of the system when the system is started, AmbientService service program is started when the system is started, the dial program realizes AmbientActivity interface realization, and registers in AmbientService.
(II) flow:
1. the system enters dream mode and notifies AmbientDream.
AmbientDream informs Ambientservice dreamingStarted (service launch control).
And 3, reading the configuration of the AmbientConfig by the Ambientservice to carry out power consumption related setting.
And 4, the Ambientservice informs the registered AmbientActivity to enter the ambient mode to change the page rendering.
And 5, enabling the Ambientservice to wake up the system (through an Alarm timing wake-up system built in the system) at a timing according to the AmbientConfig refresh frequency and informing the AmbientActivity to carry out page UI refresh operation.
And 6, controlling an AmbientActivity page refreshing operation by Ambientservice and then performing a sleeping operation on the system.
AmbientDraam informs Ambientservice dreamingStop (end of service control).
Ambientservice informs AmbientActivity to exit the ambient mode.
(III) the advantages are that:
1. the upper layer has UI rendering capability and is flexible to realize.
2. After the system enters the ambient mode, the UI effect before awakening can be kept on the screen, but the power saving effect is achieved through the means of power saving strategy backlight closing, network limitation, alarm awakening control and the like.
And 3, in the ambient mode, the system awakens short information every time and only carries out operations such as UI refreshing and the like, the power consumption curve is increased in section information, but the average power consumption is only slightly improved on the original basis, and the power saving and display effects are considered.
And S150, the interface of the mobile industry processor enters the ultra-low power consumption mode again.
In other cases, such as when the terminal encounters a wake-up event, the MIPI exits ULPS mode, the LCD exits IDLE mode, and the terminal resumes normal display mode. At this time, normal backlight brightness can be set, and normal CPU frequency can be set. The wake event includes, but is not limited to: the user presses the power key; a user touches the liquid crystal screen; the user makes hand-lifting, wrist-rotating and other gestures.
As shown in fig. 5, the present invention also provides a low power consumption constantly displayed information device 200 for a terminal having a liquid crystal display, the device comprising the following modules:
and the switching module 210 is configured to switch the liquid crystal display screen to an idle mode, and adjust the display power consumption to an ultra-low power consumption display state.
And the low-power-consumption display module 220 is used for displaying the acquired terminal dial plate information in an ultra-low-power-consumption display state.
And the clock interrupt module 230 is used for periodically starting real-time clock interrupt so that the mobile industry processor interface exits the ultra-low power consumption mode. Every fixed period (e.g., 1 minute), a Real Time Clock (RTC) interrupt is initiated and the MIPI exits ULPS mode.
And the dial plate refreshing module 240 is used for refreshing dial plate information display. The dial application refreshes the display of information once and the duration of the information may be, for example, 3-5 seconds. And then the MIPI enters the ULPS mode again, and the cyclic display is carried out in such a way, so that the aim of regularly updating dial information display is fulfilled. Here, the real time clock is provided by the CPU.
And the wake-up module 250 is used for exiting the MIPI mode from the ULPS mode, exiting the LCD mode from the IDLE mode and recovering the terminal to the normal display mode when the terminal encounters a wake-up event. At this time, normal backlight brightness can be set, and normal CPU frequency can be set. The wake event includes, but is not limited to: the user presses the power key; a user touches the liquid crystal screen; the user makes hand-lifting, wrist-rotating and other gestures.
By the method and the device, the invention realizes the switching between the normal display mode and the low-power consumption normal display mode, and a user can select the two modes to switch according to the use condition of the user. By the mode, the intelligent device disclosed by the invention can realize the technical effect of continuously displaying information for 24 hours, and overcomes the technical defect that the information cannot be continuously displayed in the prior art.
Although the smart watch is used in the embodiment of the invention to schematically show the beneficial effects of the invention, any terminal with a display screen and needing to be displayed frequently can also adopt the technical scheme of the invention. When the equipment provided by the invention is used for dormancy, the UI has high customizability, and as long as the dormant page inherits the AmbientActivity, the self content refreshing method is realized, and various data such as weather, step counting data and the like can be displayed. The display information is only an illustrative example of the present invention.
