Description

Technical Field

[0001] The present invention relates to the technical field of electronic equipment, and in particular to a method for displaying time and electronic equipment. Background Art

[0002] With the development of electronic technology, electronic devices such as smart phones and tablet computers are becoming more and more popular, and users are becoming more and more dependent on electronic devices. Taking mobile phones as an example, users turn on their mobile phone screens many times a day, and most of the time they turn on their mobile phone screens to check the time and various notifications. In order to meet people's functional requirements for electronic devices, many electronic devices are equipped with always on display (AOD) functions to improve the display effect and user experience of electronic devices.

[0003] When a digital clock is displayed on the screen-off display interface of an electronic device, a pattern can be displayed as the background or foreground of the digital clock. The current screen-off display effect is: the positional relationship between the digital clock and the pattern is a front-to-back relationship. One is that the digital clock is superimposed on the pattern, forming a visual effect of the number in front and the pattern in the back; the other is that the pattern is superimposed on the digital clock, forming a visual effect of the pattern in front and the number in the back. Both of these display effects are single and cannot meet the user's pursuit of richer display effects. Summary of the invention

[0004] The embodiments of the present application provide a method for displaying time and an electronic device, so as to provide a user with a richer display effect when a digital clock is displayed when the electronic device is in a screen-off display state.

[0005] In a first aspect, an embodiment of the present application provides a method for displaying time, which is applied to an electronic device with a display screen, the method comprising: the electronic device obtains a first picture, a second picture and a third picture, wherein the first picture includes a first part of a target control, the second picture includes a second part of the target control, and the third picture includes a digital clock; the electronic device superimposes the first picture, the third picture and the second picture in sequence to generate a picture to be displayed, wherein, in the picture to be displayed, the first part and the second part of the target control constitute the target control, and the target control overlaps with at least one digital part of the digital clock; when the display screen is in a screen-off display state, the picture to be displayed is displayed.

[0006] Based on this scheme, the electronic device sequentially superimposes a first picture including the first part of the target control, a third picture including a digital clock, and a second picture including the second part of the target control to generate a screen to be displayed. In the generated screen to be displayed, the first part and the second part of the target control constitute the target control, which can form a visual effect of the first part of the target control being displayed behind the number and the second part of the target control being displayed in front of the number, which is interspersed with each other. Compared with the display effect of a single front-to-back relationship between the number and the entire target control, this scheme can provide users with richer display effects when displaying a digital clock when the electronic device is in the screen-off display state.

[0007] In one possible design, the digital clock includes numbers for representing hours and numbers for representing minutes, and the numbers for representing hours and the numbers for representing minutes are located in different rows; the numbers for representing hours include a first digit located in the tens place and a second digit located in the ones place; the target control included in the screen to be displayed partially overlaps with the first digit.

[0008] In this design, the first digit is a digit located at the tens place representing the hour, and its possible values ​​are 0, 1, and 2. During the timing of the digital clock, the first digit changes 3 times within 24 hours of timing. Compared with the second, third, and fourth digits, the frequency of change is lower, which can save power consumption.

[0009] In a possible design, the electronic device obtains the first picture and the third picture in the following manner: calling the first picture and the third picture according to the file names of the first picture and the third picture, respectively; wherein the file name of the first picture is: the layout type of the digital clock, the value of the number on the digital clock that partially overlaps with the target control, and the positional relationship between the first picture and the digital clock; and the file name of the third picture is: the clock layout type of the digital clock, the value of the number on the digital clock that partially overlaps with the target control, and the positional relationship between the third picture and the digital clock.

[0010] For example, the layout type of the digital clock is a single clock layout, the value of the numbers on the digital clock that partially overlap with the target control is 0, the position relationship between the first picture and the digital clock is that the first picture is the background of the digital clock, and the position relationship between the first picture and the digital clock is that the first picture is the foreground of the digital clock. In this example, the file name of the first picture is: single_digit0_bg.png, and the file name of the second picture is: single_digit0_fg.png.

[0011] In a possible design, the size of the first part of the target control is smaller than the size of the first image, and the size of the second part of the target control is smaller than the size of the second image. In this design, the target control does not fill the entire superimposed image, that is, there is a transparent hollow area in the image to be displayed. In this way, when the image to be displayed is displayed in the off-screen display state, only the pixels in the area where the target control is located need to emit light, which can prevent screen burn-in.

[0012] In a possible design, the layout of the digital clock can be a single clock layout or a dual clock layout.

[0013] In one possible design, each digit included in the digital clock corresponds to three groups of image resources. The three groups of image resources include a group of image resources corresponding to a single clock layout and two groups of image resources corresponding to two clocks in a dual clock layout. Each group of image resources includes a first image as a background layer and a second image as a foreground layer.

[0014] In a possible design, the image formats of the first image, the second image and the third image are all in the image file storage png format. In the to-be-displayed picture generated by superimposing the first image, the second image and the third image, the other areas except the numbers and the target controls on the digital clock are transparent hollow effects.

[0015] In a possible design, the target control may be a pattern, including but not limited to a bird pattern, a fish picture, a fan pattern, etc. The target control may also include at least two patterns, for example, the target control is composed of two fish, one fish is superimposed on the first number on the digital clock as the first part of the target control, and becomes the background of the first number, and the other fish is superimposed on the first number as the second part of the target control, and becomes the foreground of the first number, so that the generated image to be displayed includes the target control composed of two fish.

[0016] In a possible design, when the display screen is in the off-screen display state, the first information can also be displayed; wherein the color of the first information can be set to be consistent with the color of the digits on the digital clock. For example, the first information may include but is not limited to information such as location, icon, date, and push message, and the color of the first information is set to be consistent with the color of the digits on the digital clock, which helps to improve the user experience.

[0017] In one possible design, the method may also include: the electronic device detects a click operation on the target control, and in response to the click operation, plays the time of a digital clock.

[0019] In one possible design, the digital clock includes numbers for representing hours and numbers for representing minutes, and the numbers for representing hours and the numbers for representing minutes are located in different rows; the numbers for representing hours include a first digit located in the tens place and a second digit located in the ones place; the target control included in the screen to be displayed partially overlaps with the first digit.

[0021] In a possible design, the size of the first part of the target control is smaller than the size of the first picture, and the size of the second part of the target control is smaller than the size of the second picture.

In other embodiments of the present application, the electronic device 100 may also adopt different interface connection methods in the above embodiments, or a combination of multiple interface connection methods.

[0069] The charging management module 140 is used to receive charging input from a charger. The charger may be a wireless charger or a wired charger.

[0074] The modem processor may include a modulator and a demodulator. Among them, the modulator is used to modulate the low-frequency baseband signal to be sent into a medium-high frequency signal. The demodulator is used to demodulate the received electromagnetic wave signal into a low-frequency baseband signal. The demodulator then transmits the demodulated low-frequency baseband signal to the baseband processor for processing. After the low-frequency baseband signal is processed by the baseband processor, it is passed to the application processor. The application processor outputs a sound signal through an audio device (not limited to a speaker 170A, a receiver 170B, etc.), or displays an image or video through a display screen 194.

[0077] The electronic device 100 implements the display function through a GPU, a display screen 194, and an application processor. The GPU is a microprocessor for image processing, which connects the display screen 194 and the application processor. The GPU is used to perform mathematical and geometric calculations for graphics rendering. The processor 110 may include one or more GPUs that execute program instructions to generate or change display information.

[0078] The display screen 194 is used to display images, videos, etc. The display screen 194 includes a display panel.

[0080] The electronic device 100 can realize the shooting function through ISP, camera 193, video codec, GPU, display screen 194 and application processor.

[0081] ISP is used to process the data fed back by camera 193. For example, when taking a photo, the shutter is opened, and the light is transmitted to the camera photosensitive element through the lens. The light signal is converted into an electrical signal, and the camera photosensitive element transmits the electrical signal to ISP for processing and converts it into an image visible to the naked eye. ISP can also perform algorithm optimization on the noise, brightness, and skin color of the image. ISP can also optimize the exposure, color temperature and other parameters of the shooting scene. In some embodiments, ISP can be set in camera 193.

[0082] The camera 193 is used to capture still images or videos. The object generates an optical image through the lens and projects it onto the photosensitive element. The photosensitive element can be a charge coupled device (CCD) or a complementary metal-oxide-semiconductor (CMOS) phototransistor. The photosensitive element converts the optical signal into an electrical signal, and then passes the electrical signal to the ISP to be converted into a digital image signal. The ISP outputs the digital image signal to the DSP for processing. The DSP converts the digital image signal into an image signal in a standard RGB, YUV or other format. In some embodiments, the electronic device 100 may include 1 or N cameras 193, where N is a positive integer greater than 1.

[0100] The proximity light sensor 180G may include, for example, a light emitting diode (LED) and a light detector, such as a photodiode. The light emitting diode may be an infrared light emitting diode. The electronic device 100 emits infrared light outward through the light emitting diode. The electronic device 100 uses a photodiode to detect infrared reflected light from nearby objects.

In this case, the fingerprint sensor can be configured in the touch screen, can be a part of the touch screen, or can be configured in the touch screen in other ways. In addition, the fingerprint sensor can also be implemented as a full-panel fingerprint sensor, so the touch screen can be regarded as a panel where fingerprint collection can be performed at any position. In some embodiments, the fingerprint sensor can process the collected fingerprint (for example, whether the fingerprint is verified) and send it to the processor 110, and the processor 110 performs corresponding processing according to the fingerprint processing result.

[0107] Motor 191 can generate vibration prompts. Motor 191 can be used for incoming call vibration prompts, and can also be used for touch vibration feedback. For example, touch operations acting on different applications (such as taking pictures, audio playback, etc.) can correspond to different vibration feedback effects. For touch operations acting on different areas of the display screen 194, motor 191 can also correspond to different vibration feedback effects. Different application scenarios (for example: time reminders, receiving messages, alarm clocks, games, etc.) can also correspond to different vibration feedback effects. The touch vibration feedback effect can also support customization.

The eSIM card can be embedded in the electronic device 100 and cannot be separated from the electronic device 100.

[0110] although Figure 1 Not shown, the electronic device 100 may further include a Bluetooth device, a positioning device, a flashlight, a micro-projection device, a near field communication (NFC) device, etc., which are not described in detail here.

[0111] The following embodiments can all be implemented in an electronic device 100 (such as a mobile phone, tablet computer, etc.) having the above hardware structure. Figure 1 The hardware structure of the electronic device 100 has been described. The following embodiments take the Android system with a layered architecture as an example to exemplify the software structure of the electronic device 100.

[0112] Figure 2 1 is a software structure block diagram of the electronic device 100 according to an embodiment of the present invention.

[0113] like Figure 2 As shown, the software structure of the electronic device adopts a layered architecture, which divides the software into several layers, each layer has a clear role and division of labor. The layers communicate with each other through software interfaces. In some embodiments, the Android system is divided into four layers, from top to bottom, namely, the application layer, the application framework layer, the Android runtime (Android runtime) and the system library, and the kernel layer.

[0114] The application layer can include a series of application packages. Figure 2 As shown, the application package may include applications such as phone, camera, gallery, calendar, call, map, navigation, WLAN, Bluetooth, music, video, short message, etc.

[0115] The application framework layer provides application programming interface (API) and programming framework for the applications in the application layer. The application framework layer includes some predefined functions. Figure 2 As shown, the application framework layer may include a window manager, a content provider, a view system, a phone manager, a resource manager, a notification manager, and the like.

[0116] The window manager is used to manage window programs. The window manager can obtain the display screen size, determine whether there is a status bar, lock the screen, capture the screen, etc.

[0117] Content providers are used to store and retrieve data and make it accessible to applications. The data may include videos, images, audio, calls made and received, browsing history and bookmarks, phone books, etc.

[0118] The view system includes visual controls, such as controls for displaying text, controls for displaying images, etc. The view system can be used to build applications. A display interface can be composed of one or more views. For example, a display interface including a text notification icon can include a view for displaying text and a view for displaying images.

[0119] The phone manager is used to provide communication functions of the electronic device 100, such as management of call status (including connecting, hanging up, etc.).

[0120] The resource manager provides various resources for applications, such as localized strings, icons, images, layout files, video files, etc.

[0121] The notification manager enables applications to display notification information in the status bar. It can be used to convey notification-type messages and can disappear automatically after a short stay without user interaction. For example, the notification manager is used to notify download completion, message reminders, etc. The notification manager can also be a notification that appears in the system top status bar in the form of a chart or scroll bar text, such as notifications of applications running in the background, or a notification that appears on the screen in the form of a dialog window. For example, a text message is displayed in the status bar, a prompt sound is emitted, an electronic device vibrates, an indicator light flashes, etc.

[0122] Android Runtime includes core libraries and virtual machines. Android runtime is responsible for scheduling and management of the Android system.

[0123] The core library consists of two parts: one part is the function that needs to be called by the Java language, and the other part is the Android core library.

[0124] The application layer and the application framework layer run in a virtual machine. The virtual machine executes the Java files of the application layer and the application framework layer as binary files. The virtual machine is used to perform functions such as object life cycle management, stack management, thread management, security and exception management, and garbage collection.

[0125] The system library may include multiple functional modules, such as surface manager, media library, 3D graphics processing library (such as OpenGL ES), 2D graphics engine (such as SGL), etc.

[0126] The surface manager is used to manage the display subsystem and provide the fusion of 2D and 3D layers for multiple applications.

[0127] The media library supports playback and recording of a variety of commonly used audio and video formats, as well as static image files, etc. The media library can support a variety of audio and video encoding formats, such as: MPEG4, H.264, MP3, AAC, AMR, JPG, PNG, etc.

[0128] The 3D graphics processing library is used to implement 3D graphics drawing, image rendering, compositing, and layer processing.

[0129] A 2D graphics engine is a drawing engine for 2D drawings.

[0130] The kernel layer is the layer between hardware and software. The kernel layer contains at least display driver, camera driver, audio driver, and sensor driver.

[0131] Some exemplary user interfaces (UI) provided by the electronic device 100 are introduced below. The term "user interface" in the specification, claims and drawings of this application refers to a medium interface for interaction and information exchange between an application or operating system and a user, which realizes the conversion between the internal form of information and the form acceptable to the user. A common form of user interface is a graphical user interface (GUI), which refers to a user interface related to computer operations displayed in a graphical manner. It can be an interface element such as an icon, window, control, etc. displayed on the display screen of an electronic device, wherein the control may include icons, buttons, menus, tabs, text boxes, dialog boxes, status bars, navigation bars, widgets, etc. Visual interface elements.

[0132] Figure 3 The example in FIG. 1 shows a user interface 300 displayed on the display screen 194 of the electronic device 100 .

[0133] like Figure 3 As shown, the user interface 300 is a screen-off display interface of an electronic device. The user interface 300 may include a digital clock 301, and the digital clock 301 may include time digits. The layout style of the digital clock may be horizontal display, that is, the digits used to represent the hours and the digits used to represent the minutes are displayed in the same row (or line). It should be understood that Figure 3 The layout style of the digital clock in the embodiment of the present application is not limited. The layout style of the digital clock in the present application may also be other styles, such as double-row display. Figure 4a ,or Figure 4b ,or Figure 4cAs shown, the numbers used to represent the hours and the numbers used to represent the minutes are not displayed in the same row (or line). The numbers used to represent the hours may be in the first row (or line) and the numbers used to represent the minutes may be in the second row (or line), or the numbers used to represent the minutes may be in the first row (or line) and the numbers used to represent the hours may be in the second row (or line).

[0134] In some other embodiments, the user interface 300 may also include a date 302 and a weather widget 303, etc., and may also include icons 304 of various applications, such as a WeChat icon, a phone icon, a text message icon, and remaining power, etc. In some other embodiments, the user interface 300 may also include a push message 305, such as a WeChat message reminder.

[0135] Understandably, Figure 3 The screen-off display interface on the electronic device 100 is merely illustrated as an example and does not constitute a limitation on the embodiments of the present application.

[0136] When an electronic device displays a digital clock in the off-screen display scenario, the bird pattern is used as the background or foreground of the digital clock. The visual effects formed mainly include two types: one is Figure 4a As shown in the figure, time is superimposed on the bird pattern, creating a visual effect of time in front and the bird pattern behind. Figure 4b As shown, the bird pattern is superimposed on the time, forming a visual effect that the bird pattern is in front and the time is behind. Both of these visual effects are relatively simple and cannot meet the user's pursuit of richer display effects.

[0137] To this end, the present application provides a method for displaying time, which is applicable to an electronic device with a display screen, and the electronic device has an off-screen display function. In the method, the electronic device obtains a first picture, a second picture, and a third picture, wherein the first picture includes a first part of a target control, the second picture includes a second part of the target control, and the third picture includes a digital clock. The first picture, the third picture, and the second picture are superimposed in sequence to generate a picture to be displayed, in which the first part of the target control becomes the background (background, bg) of the digital clock, and the second part of the target control becomes the foreground (foreground, fg) of the digital clock. The first part as the background and the second part as the foreground form a complete target control, and the target control overlaps with at least one digital part of the digital clock. For example, the target control is a complete bird pattern, such as Figure 4cAs shown, the first picture includes the first part of the target control, namely, the tail of the bird, the second picture includes the digital clock, and the third picture includes the second part of the target control, namely, the front part of the bird. In the screen to be displayed obtained by superimposing these three pictures, the tail of the bird serves as the background of the number "0" included in the digital clock, and the front part of the bird serves as the foreground of the number "0", forming a visual effect in which the first part of the target control is in front of the number "0" and the second part of the target control is behind the number "0" that is interspersed with each other. Compared with the display effect in which the number "0" and the entire target control form a single front-to-back relationship, the method for displaying time in the present application can provide users with richer display effects when displaying a digital clock when the electronic device is in the screen-off display state.

[0138] It should be understood that the method for displaying time provided in the embodiments of the present application is not only applicable to digital clocks, but also to analog clocks. The following embodiments only take digital clocks as an example.

[0139] The following will describe in detail the method for displaying time provided in the embodiments of the present application in conjunction with the accompanying drawings.

[0140] In the embodiments of the present application, the digital clock may be in 24-hour format or 12-hour format. For ease of description, the following embodiments are described using the 24-hour format of the digital clock as an example.

[0141] For example, Figure 5 As shown, the time on the digital clock is 08:08, and the time on the digital clock includes digits for indicating hours and digits for indicating minutes, and the digits for indicating hours and the digits for indicating minutes are located in different rows. The digits for indicating hours include a first digit located in the tens place and a second digit located in the units place, and the first digit can take values ​​such as 0, 1, 2, and the second digit can take values ​​such as 0, 1, 2 ... 9. The digits for indicating minutes include a third digit located in the tens place and a fourth digit located in the units place, and the third digit can take values ​​such as 0, 1, 2 ... 6, and the fourth digit can take values ​​such as 0, 1, 2 ... 9.

[0142] The target control can be superimposed with any one or more of the first number, the second number, the third number, and the fourth number on the digital clock to obtain a picture to be displayed, and the target control in the picture to be displayed is superimposed with any one or more numbers to form a visual effect of interlacing with each other. In the following embodiments, the target control is superimposed with a number on the digital clock to obtain a picture to be displayed as an example for explanation.

[0143] Taking the target control as a bird pattern as an example, the bird pattern can be superimposed with the first number on the digital clock to obtain a to-be-displayed screen, in which the bird pattern and the first number partially overlap to form an interlaced effect. Among them, the first number is a number located at the tens place representing the hour, and its possible values ​​are 0, 1, and 2. During the timing of the digital clock, the first number changes 3 times within the 24-hour timing time, which is lower than the change frequency of the second number, the third number, and the fourth number. In this way, compared with superimposing the bird pattern with other numbers (such as the second number, the third number, and the fourth number), superimposing the bird pattern with the first number can save power consumption.

[0144] The following takes the superposition of the target control (bird pattern) and the first digit of the digital clock as an example to introduce the method for displaying time in an embodiment of the present application.

[0145] In one example, the first digital value is "0", a portion of the target control is in the foreground layer, and another portion is in the background layer, such as Figure 5 As shown, picture 501 of the foreground layer includes the first part of the bird, picture 502 of the digital layer includes the number "0", and picture 503 of the background layer includes the second part of the bird. After superimposing pictures 501, 502, and 503, picture 504 is obtained. The first part of the bird and the second part of the bird in picture 504 form a complete bird pattern. In picture 504, the target control (bird pattern) and the number "0" form a visual effect of interlacing each other, that is, the first part of the bird is in front of the number "0", and the second part of the bird is behind the number "0".

[0146] In another example, the first digital value is "1", a portion of the target control is in the foreground layer, and another portion is in the background layer, such as Figure 5 As shown, picture 511 of the foreground layer includes the first part of the bird, picture 512 of the digital layer includes the number "1", and picture 513 of the background layer includes the second part of the bird. Picture 514 is obtained by superimposing pictures 511, 512, and 513. The first part of the bird and the second part of the bird in picture 514 form a complete bird pattern. In picture 514, the target control (bird pattern) and the number "1" form a visual effect of interlacing each other, that is, the first part of the bird is in front of the number "1", and the second part of the bird is behind the number "1".

[0147] In another example, the first number is set to "2", and all target controls are in the foreground layer, such as Figure 5As shown, picture 521 of the foreground layer includes a whole bird, picture 522 of the digital layer includes the number "2", and picture 523 of the background layer has no pattern. After superimposing pictures 521, 522, and 523, picture 524 is obtained. In picture 524, the target control (bird pattern) has a visual effect completely in front of the number "2".

[0148] In the above examples, the value of the first digit of the digital clock is different. The target control can be divided differently according to the different shapes of the digits "0", "1", and "2". The first part of the target control in the picture of the foreground layer corresponding to each different value is different, and the second part of the target control in the picture of the background layer corresponding to each value is also different. Therefore, after superimposing the pictures of the foreground layer, the digit layer, and the background layer corresponding to each value, the visual effects of the superimposed target control (bird pattern) and the first digit in the obtained pictures 504, 514, and 524 are also different. In this way, the bird pattern can be flexibly combined with the shape of the digit, and different superposition effects can be displayed as the time of the digital clock changes, thereby providing users with richer visual effects.

[0149] In the embodiment of the present application, any picture format of the background layer picture, the digital layer picture and the foreground layer picture is an image file storage (portable network graphic, png) format, so that the areas except the bird pattern in the background layer picture and the foreground layer picture are transparent hollow effects, and the areas except the numbers in the digital layer picture are transparent hollow effects. After the three layers of pictures are superimposed, the display of the numbers on the digital clock will not be affected, nor will the display of the bird pattern be affected. Moreover, only the pixels in the area where the digital clock and the target control (bird pattern) are located need to emit light on the screen to be displayed, which can save power consumption.

[0150] The above example only introduces the visual effect of the screen off display by superimposing the first number and the bird pattern. The method of displaying the time by superimposing the second number, the third number, the fourth number and the target control can refer to the relevant description of the above example, which will not be repeated here.

[0151] In the embodiment of the present application, the layout of the digital clock can be as follows: Figure 6 The single clock layout shown is Figure 6 As shown, a digital clock 601 is displayed on the screen display interface. For example, the electronic device can obtain the current geographical location and set the time of the digital clock 601 according to the time zone of the current geographical location. In some other embodiments, the layout of the digital clock can also be as follows: Figure 7The dual clock layout shown in the figure can display the time of two different locations. For example, one of the digital clocks can set the time according to the time zone corresponding to the home location (such as the registered residence, the usual residence, etc.), and the other digital clock can set the time according to the time zone corresponding to the current location of the electronic device (such as the business trip location). Figure 7 As shown, the screen display interface displays a digital clock 701 and a digital clock 703. For example, the time corresponding to the digital clock 701 is the local time and date in Hohhot, China. A house icon (as shown in a dotted box 702) is displayed below the digital clock 701. The time of the digital clock 701 is the time in the time zone where the home is located. The time corresponding to the digital clock 703 is the local time and date in Amsterdam. A positioning icon (as shown in a dotted box 704) is displayed below the digital clock 703. The time of the digital clock 703 is the time in the time zone where the electronic device is currently located.

[0152] Taking the superimposed display of the target control and the first digit as an example, the first digit can take values ​​of 0, 1, and 2, and each value of the first digit can correspond to three groups of image resources, including a group of single clock image resources and two groups of dual clock image resources. A group of image resource files can be named: clock type_digit n_background.png and clock type_digit n_foreground.png, where the single clock is prefixed with single and the dual clock is prefixed with dual. For example, if the value of the first digit is "0", the digit n can be represented as digit 0; if the value of the first digit is "1", the digit n can be represented as digit1; if the value of the first digit is "2", the digit n can be represented as digit2.

[0153] Taking the value of the first digit as "2" as an example, the corresponding file names of a set of single-clock image resources are: single_digit2_bg.png and single_digit2_fg.png, and the corresponding file names of the two sets of dual-clock image resources are: dual1_digit2_bg.png, dual1_digit2_fg.png, dual2_digit2_bg.png, dual2_digit2_fg.png.

[0154] In the embodiment of the present application, the image size of the image resource can be set to a fixed size, which does not change with the change of the time number. For example, taking a single clock layout as an example, the width corresponding to the image size of the single clock image resource can be set to be consistent with the width of the display screen, such as Figure 8a The width is 360dp and the height is 248dp. Taking the dual clock layout as an example, the image specifications of each dual clock image resource (image 820 and image 830) can be as follows: Figure 8bThe width shown is 180dp and the height is 248dp.

[0155] In this example, in the image corresponding to each image resource, the size of the target control is smaller than the size of the image, for example Figure 8a Taking the picture 810 shown as an example, the size of the picture is 360dp in width and 248dp in height. The bird pattern 811 in the picture does not fill the entire picture, that is, there is a transparent hollow area in the picture 810. In this way, when the picture 810 is displayed on the screen-off display interface, only the pixels in the area where the bird pattern 811 is located need to emit light, which can prevent screen burn-in.

[0156] In addition, setting the image size larger can support the display of target controls of various shapes and sizes. When designing superimposed target controls for digital clocks, the size of the target control will not be limited to one, which may cause the target control to fail to display when replaced with a larger target control.

[0157] The following is an introduction to the AOD layout.

[0158] For example, the AOD layout is shown in the theme.xml file:

[0159]

[0160]

[0161] In the AOD layout, the layout style of the data clock can be as follows Figure 3 The horizontal display style shown can also be Figure 4a , Figure 4b , Figure 4c Double-row display style as shown in the figure.

[0162] In some embodiments, the value of the foreground image position can represent the display position of a part of the target control in the picture of the foreground layer on the digital clock, and the value of the background image position can represent the display position of another part of the target control in the picture of the background layer on the digital clock. The optional values ​​of the foreground image position and the background image position are 0, 1, and 2. When the values ​​of the foreground image position and the background image position are "0", it means that with the change of time, the corresponding foreground layer picture and background layer picture do not change. When designing the display effect of the target control, it is necessary to avoid the display area of ​​the digital clock to ensure that the numbers are not blocked.

[0163] When the values ​​of the foreground image position and the background image position are "1", the target control is displayed at the first digit position. Since the first digit of the 24-hour digital clock can be 0, 1, or 2, each value can correspond to three groups of image resources.

[0164] When the value of the first number is "0", the corresponding three groups of image resources are named as follows:

[0165] single_digit0_fg.png, single_digit0_bg.png;

[0166] dual1_digit0_fg.png, dual1_digit0_bg.png;

[0167] dual2_digit0_fg.png, dual2_digit0_bg.png.

[0168] When the value of the first number is "1", the corresponding three groups of image resources are named as follows:

[0169] single_digit1_fg.png, single_digit1_bg.png;

[0170] dual1_digit1_fg.png, dual1_digit1_bg.png;

[0171] dual2_digit1_fg.png, dual2_digit1_bg.png.

[0172] When the value of the first number is "2", the corresponding three groups of image resources are named as follows:

[0173] single_digit2_fg.png, single_digit2_bg.png;

[0174] dual1_digit2_fg.png, dual1_digit2_bg.png;

[0175] dual2_digit2_fg.png, dual2_digit2_bg.png.

[0176] The names of the above-mentioned image resources must match and cannot be changed. When 0, 1, and 2 are displayed at the position of the first digit respectively, the image of the foreground layer and the image of the background layer corresponding to the value of the first digit are displayed at the same time. In this way, different visual effects after the target control and the first digit are superimposed can be displayed according to the change of the value of the first digit.

[0177] When the value of the foreground image position and the background image position is "2", the target control is displayed at the second digit position. Since the value of the second digit of the 24-hour digital clock can be 0, 1, 2, ... 9, each value can correspond to three groups of image resources.

[0178] When the value of the second digit is "0", the corresponding three groups of image resources are named as follows:

[0179] single_digit0_fg.png, single_digit0_bg.png;

[0180] dual1_digit0_fg.png, dual1_digit0_bg.png;

[0181] dual2_digit0_fg.png, dual2_digit0_bg.png.

[0182] When the value of the second number can be "1", the corresponding three groups of image resources are named as follows:

[0183] single_digit1_fg.png, single_digit1_bg.png;

[0184] dual1_digit1_fg.png, dual1_digit1_bg.png;

[0185] dual2_digit1_fg.png, dual2_digit1_bg.png.

[0186] …

[0187] When the value of the second digit can be "9", the corresponding three groups of image resources are named as follows:

[0188] single_digit9_fg.png, single_digit9_bg.png;

[0189] dual1_digit9_fg.png, dual1_digit9_bg.png;

[0190] dual2_digit9_fg.png, dual2_digit9_bg.png.

[0191] The names of the above-mentioned image resources must match and cannot be changed. When 0, 1, 2, ... 9 are displayed in the position of the second digit respectively, the foreground image and background image corresponding to the value of the second digit are also displayed in the position of the second digit.

[0192] In some other embodiments, the target control can also be displayed on the digits representing minutes of a digital clock, and in this case, the foreground image position and the background image position can also be selected as 3 or 4.

[0193] When the values ​​of the foreground image position and the background image position are "3", the target control is displayed at the position of the third digit. Since the value of the third digit of the 24-hour digital clock can be 0, 1, 2...6, each value can correspond to three groups of image resources.

[0194] When the value of the third digit is "0", the corresponding three groups of image resources are named as follows:

[0195] single_digit0_fg.png, single_digit0_bg.png;

[0196] dual1_digit0_fg.png, dual1_digit0_bg.png;

[0197] dual2_digit0_fg.png, dual2_digit0_bg.png.

[0198] …

[0199] When the value of the third digit can be "6", the corresponding three groups of image resources are named as follows:

[0200] single_digit6_fg.png, single_digit6_bg.png;

[0201] dual1_digit6_fg.png, dual1_digit6_bg.png;

[0202] dual2_digit6_fg.png, dual2_digit6_bg.png.

[0203] The names of the above-mentioned image resources must match and cannot be changed. When 0, 1, 2, ... 9 are displayed at the position of the third digit respectively, the foreground image and background image corresponding to the value of the third digit are also displayed at the position of the third digit.

[0204] When the value of the foreground image position and the background image position is "4", the target control is displayed at the position of the fourth digit. Since the value of the third digit of the 24-hour digital clock can be 0, 1, 2...9, each value can correspond to three groups of image resources. For specific image resources, please refer to the naming of the image resources corresponding to each value of the second digit when the value of the foreground image position and the background image position is "2", which will not be repeated here.

[0205] In the AOD layout, the numbers on the digital clock are in picture format, and the color of the numbers cannot be changed. When other information is displayed on the screen display interface in addition to the digital clock, the color of the other information may be different from that of the numbers. In the embodiment of the present application, the color of the other information can be set to change. Generally, the default color can be set to white. When the color of other information needs to be changed, it can be achieved by modifying the value of item fondcolor in the theme.xml file.

[0206] In an example, taking a single clock layout as an example, Figure 6 As shown, the color of the date (such as the Gregorian calendar date, the lunar calendar date, etc.), various application icons, and information such as the battery level (such as the information marked by the dotted box 602) displayed below the digital clock 601 can be set. In this way, by changing the color of the information marked by the dotted box 602, the digital clock displayed on the screen-off display interface can be made consistent with the color of other information, which helps to improve the user experience.

[0207] In another example, taking a dual clock layout as an example, Figure 7 As shown, the color of the information such as location, icon, date (such as Gregorian calendar date, day of the week, etc.) displayed below the digital clock 701 (such as the information marked by the dotted box 702) can be set, and the color of the information such as location, icon, date (such as Gregorian calendar date, day of the week, etc.) displayed below the digital clock 703 (such as the information marked by the dotted box 704) can be set. In this way, by changing the color of the information marked by the dotted box 702 and the dotted box 704, the digital clock displayed on the screen-off display interface can be made consistent with the color of other information, which helps to improve the user experience.

[0208] In an embodiment of the present application, the target control may be a pattern of a bird as in the above example, or may be a pattern of other objects, including but not limited to a pattern of a flower, a pattern of the moon, a pattern of a fan, etc., which are not listed here one by one.

[0209] In the above embodiment, the target control includes a pattern of an object (such as a bird), and the target control is displayed superimposed with a number of a digital clock.

[0210] In some other embodiments, the target control may be displayed in superposition with multiple digits of the digital clock to form an interlaced visual effect. It should be understood that the target control may be a pattern of one object or may include patterns of multiple objects.

[0211] The following takes the example of a target control including two object patterns, where the two objects are different goldfish patterns, and the example of a target control and two digital overlay displays to introduce another possible implementation of the method for displaying time of the present application.

[0212] See also Fig. 9 , the target control includes goldfish 01 in picture 901 and goldfish 02 in picture 903, picture 902 includes a digital clock, and pictures 901, 902, and 903 are superimposed, goldfish 01 in picture 901 is used as the background layer of two numbers (the first number and the third number) of the digital clock, and goldfish 02 in picture 903 is used as the foreground layer of two numbers (the first number and the third number) of the digital clock. After that, a to-be-displayed screen 904 is obtained. In the to-be-displayed screen 904, goldfish 01 and goldfish 02 constitute the target control, which can form a visual effect in which goldfish 01 is behind the first number (value is 0) and the third number (value is 0) (i.e., the background), and goldfish 02 is in front of the first number (value is 0) and the third number (value is 0) (i.e., the background) interlaced with each other.

[0213] In other embodiments, the goldfish 01 in picture 901 and the goldfish 02 in picture 903 may be superimposed with only one digit of the digital clock to form a visual effect of interlacing, or may be superimposed with three digits of the digital clock to form a visual effect of interlacing, or may be superimposed with four digits of the digital clock to form a visual effect of interlacing. For specific implementation methods, see Fig. 9 The examples are not repeated here.

[0214] exist Fig. 9 In the example shown, the relevant contents of the AOD layout can refer to the relevant contents of the AOD layout in the aforementioned embodiment, which will not be repeated here.

[0215] In an embodiment of the present application, the picture to be displayed on the screen-off display interface can be displayed at the same position of the display screen all the time, or it can be displayed at a different position at intervals. For example, a first number of pixels are moved every preset time to display the picture to be displayed. For example, a few pixels can be moved every 1 minute to display the picture to be displayed. The longer the preset time is set, the larger the value of the first number is. In this way, the display position of the picture to be displayed on the electronic device in the screen-off display state can be changed at regular intervals, so that the pixels that are lit up on the display screen when displaying the picture to be displayed at regular intervals are different. Compared with the electronic device lighting up the same pixels when displaying the picture to be displayed in the screen-off display state, the risk of pixel damage can be reduced, thereby reducing the risk of screen burn-in in the electronic device.

[0216] In this embodiment, when displaying the picture to be displayed in the screen-off state, the picture to be displayed can be displayed in two non-overlapping areas at intervals. In this way, the pixels that light up when the two non-overlapping areas display the pattern to be displayed are completely different, which can further reduce the risk of screen burn-in.

[0217] In combination with the above embodiments and drawings, the present application embodiment provides a method for displaying a screen off. The method can be used in a Figure 1 The electronic device of the hardware structure shown in FIG. Fig.10 As shown, the screen-off display method in the embodiment of the present application may include the following steps:

[0218] Step 1001, obtain a first picture, a second picture and a third picture, wherein the first picture includes a first part of a target control, the second picture includes a second part of a target control, and the third picture includes a digital clock. The layout of the digital clock can be a single clock layout or a dual clock layout.

[0219] For example, Fig. 9 For example, the first picture may be picture 901, the second picture may be picture 903, the third picture may be picture 902, and the target control may be a bird pattern.

[0220] Step 1002, superimpose the first picture, the third picture and the second picture in sequence to generate a picture to be displayed, wherein in the picture to be displayed, the first part and the second part of the target control constitute the target control, and the target control overlaps with at least one digital part of the digital clock.

[0221] For example, Fig. 9 For example, after superimposing picture 901, picture 903, and picture 902, a picture to be displayed is obtained as shown in picture 904.

[0222] Step 1003: When the display screen is in the screen-off display state, display the picture to be displayed.

[0223] Based on this method, the electronic device sequentially superimposes a first picture including a first part of a target control, a third picture including a digital clock, and a second picture including a second part of the target control to generate a picture to be displayed. In the generated picture to be displayed, the first part and the second part of the target control constitute the target control, which can form a visual effect of the first part of the target control being displayed behind the number and the second part of the target control being displayed in front of the number, which is interspersed with each other. Compared with the display effect of a single front-to-back relationship between the number and the entire target control, this solution can provide users with richer display effects when displaying a digital clock when the electronic device is in the screen-off display state.

[0224] In one possible implementation, the digital clock includes numerals for indicating hours and numerals for indicating minutes, and the numerals for indicating hours and the numerals for indicating minutes are located in different rows. In another implementation, the numerals for indicating hours and the numerals for indicating minutes included in the digital clock may also be located in the same row.

[0225] The digits used to represent the hour include a first digit located at the tens place and a second digit located at the ones place, and the target control included in the to-be-displayed screen partially overlaps with the first digit. The first digit is a digit located at the tens place representing the hour, and its possible values ​​are 0, 1, and 2. During the timing of the digital clock, the first digit changes 3 times within the 24-hour timing time, which is lower than the change frequency of the second, third, and fourth digits, and can save power consumption.

[0226] In a possible design, the electronic device obtains the first picture and the third picture in the following manner: calling the first picture and the third picture according to the file names of the first picture and the third picture, respectively; wherein the file name of the first picture is: the layout type of the digital clock, the value of the number on the digital clock that partially overlaps with the target control, and the positional relationship between the first picture and the digital clock; and the file name of the third picture is: the clock layout type of the digital clock, the value of the number on the digital clock that partially overlaps with the target control, and the positional relationship between the third picture and the digital clock.

[0227] For example, the layout type of the digital clock is a single clock layout, the value of the numbers on the digital clock that partially overlap with the target control is 0, the position relationship between the first picture and the digital clock is that the first picture is the background of the digital clock, and the position relationship between the first picture and the digital clock is that the first picture is the foreground of the digital clock. In this example, the file name of the first picture is: single_digit0_bg.png, and the file name of the second picture is: single_digit0_fg.png.

[0228] In a possible design, the size of the first part of the target control is smaller than the size of the first image, and the size of the second part of the target control is smaller than the size of the second image. In this design, the target control does not fill the entire superimposed image, that is, there is a transparent hollow area in the image to be displayed. In this way, when the image to be displayed is displayed in the off-screen display state, only the pixels in the area where the target control is located need to emit light, which can prevent screen burn-in.

[0229] In one possible design, each digit included in the digital clock corresponds to three groups of image resources. The three groups of image resources include a group of image resources corresponding to a single clock layout and two groups of image resources corresponding to two clocks in a dual clock layout. Each group of image resources includes a first image as a background layer and a second image as a foreground layer.

[0230] In a possible design, the image formats of the first image, the second image and the third image are all in the image file storage png format. In the to-be-displayed picture generated by superimposing the first image, the second image and the third image, the other areas except the numbers and the target controls on the digital clock are transparent hollow effects.

[0231] In a possible design, the target control may be a pattern, including but not limited to a bird pattern, a fish picture, a fan pattern, etc. The target control may also include at least two patterns, for example, the target control is composed of two fish, one fish is superimposed on the first number on the digital clock as the first part of the target control, and becomes the background of the first number, and the other fish is superimposed on the first number as the second part of the target control, and becomes the foreground of the first number, so that the generated image to be displayed includes the target control composed of two fish.

[0232] In a possible design, when the display screen is in the off-screen display state, the first information can also be displayed, wherein the color of the first information can be set to be consistent with the color of the digital clock. For example, the first information may include but is not limited to location, icon, date, push message and other information, for example Figure 6 The information marked by the dotted box 602 in FIG. Figure 7 The information marked by the dotted box 702 and the dotted box 704 has a first information whose color is set to be consistent with the digital color of the digital clock, which helps to improve the user experience.

[0233] In one possible design, the method may also include: the electronic device detects a click operation on the target control, and in response to the click operation, plays the time of a digital clock.
