Description

Screen-extinguishing display method and terminal equipment

Technical Field

The application relates to the technical field of terminals, in particular to a screen-extinguishing display method and terminal equipment.

Background

With the development of terminal devices, most terminal devices support a normally bright display (always on display, AOD) function in a standby state, which may also be referred to as "off-screen display". Under the condition that the normally-bright display function is started, after the terminal equipment is turned off, preset information of screen-off display can be displayed on the screen of the terminal equipment, and an interface for displaying the information of screen-off display can be called a screen-off display interface. The information displayed on the screen may include, for example, time, power, personality pattern, notification, and the like.

Currently, most terminal devices support a screen rotation function, for example, a screen is switched from a vertical screen to a horizontal screen, and the terminal device needs to switch a vertical screen display interface to a horizontal screen display interface. In one possible scenario, the terminal device is in an awake state and displays a cross-screen display interface. And the terminal equipment responds to the pressing operation of the user on the power key, enters a standby state and displays a screen-extinguishing display interface.

However, the terminal device may display a screen-extinguishing display interface of a horizontal screen first, and then display a screen-extinguishing display interface of a vertical screen, so that an abnormal display scene appears in the terminal device, that is, a phenomenon of flashing frequency is generated when the screen-extinguishing display interface is displayed, which results in poor user experience.

Disclosure of Invention

The application provides a screen-extinguishing display method and terminal equipment, and the method is beneficial to avoiding the phenomenon of frequency flashing generated when the terminal equipment displays a screen-extinguishing display interface in a horizontal screen mode, and improving user experience.

In a first aspect, a method for displaying a screen of interest is provided, which is applied to a terminal device, and the method includes: detecting a screen-off signal, and switching the screen state of the terminal equipment from a screen-on state to a screen-off state; under the condition that screen-extinguishing display is required and the current screen direction of the terminal equipment is the horizontal screen direction, drawing a first view based on a first window layout parameter, wherein the foreground color of the first view is black, and the first window layout parameter is related to the current screen direction; switching the screen state of the terminal equipment from the screen-off state to the screen-off display state, and displaying a first view; adjusting the first window layout parameters into second window layout parameters, drawing a second view based on the second window layout parameters, wherein the foreground color of the second view is empty, and the second window layout parameters are related to the vertical screen direction; a second view is displayed.

According to the screen-off display method provided by the embodiment of the application, after the screen-off signal is detected, the screen state of the terminal equipment is switched from the screen-on state to the screen-off state; under the condition that screen-extinguishing display is required and the current screen direction of the terminal equipment is the horizontal screen direction, drawing a first view based on a first window layout parameter, wherein the foreground color of the first view is black, and the first window layout parameter is related to the current screen direction; switching the screen state of the terminal equipment from the screen-off state to the screen-off display state, and displaying a first view; and adjusting the first window layout parameters into second window layout parameters, and drawing and displaying a second view based on the second window layout parameters, wherein the foreground color of the second view is empty, and the second window layout parameters are related to the vertical screen direction. In this way, the terminal device displays the first view with black foreground color, so that the user cannot see the screen-extinguishing display interface of the horizontal screen, after the window layout parameters are adjusted, the second view with empty foreground color is drawn and displayed based on the adjusted window, and when the terminal device starts drawing the view based on the horizontal screen layout parameters and the vertical screen layout parameters are not adjusted, the screen-extinguishing display interface of the horizontal screen is prevented from being displayed, so that the abnormal display scene of the screen-flashing appears, and the user experience is improved.

Specifically, the detection of the off-screen signal by the terminal device may be that the terminal device detects the off-screen signal in response to a pressing operation of a power key by a user. The detection of the off-screen signal by the terminal device may be that the terminal device does not detect the operation of the user within a preset time, and the off-screen signal is detected.

It should be understood that after the screen state of the terminal device is switched from the bright screen state to the off screen state, the display screen of the terminal device is turned off.

Specifically, the first window layout parameter may be a window direction of the current screen. Alternatively, the first window layout parameter may be the width and height of the window of the current screen. The second window layout parameter may be the width and height of the window in the portrait orientation, or the second window layout parameter may also be the portrait window orientation.

Specifically, the following possible implementations of adjusting the first window layout parameter to the second window layout parameter are possible.

In one possible implementation, the first window layout parameter is the width and height of the window of the current screen, and the second window layout parameter is the width and height of the window in the portrait orientation. The first window layout parameter is adjusted to the second window layout parameter as follows: and taking the height of the window in the vertical screen direction as the width of the adjusted window, and taking the width of the window in the vertical screen direction as the height of the adjusted window to obtain the adjusted window layout parameter, namely the second window layout parameter. For example, the first window layout parameter has a width of 2 and a height of 1, and the adjusted window layout parameter has a width of 1 and a height of 2, i.e., the second window layout parameter has a width of 1 and a height of 2.

In another possible implementation, the first window layout parameter is a window direction of the current screen and the second window layout parameter is a vertical screen window direction. The first window layout parameter is adjusted to the second window layout parameter as follows: and adjusting the window direction from the horizontal screen direction to the vertical screen direction. For example, the window direction of the first window layout parameter is a horizontal screen direction, and the adjusted window direction is a vertical screen direction, that is, the window direction in the second window layout parameter is a vertical screen direction.

Specifically, the process of drawing the first view may be: firstly, drawing a background layer of the first view, then drawing a layer corresponding to the display element of the screen, and finally drawing a black foreground layer.

It should be appreciated that the layer corresponding to the display style on the screen may include multiple sub-views. When each of the plurality of sub-views is drawn, it is necessary to measure the width and height of each sub-view, and draw the corresponding sub-view according to the width and height of each sub-view.

Alternatively, the foreground color being black means that the color of the foreground color layer is black, and the RGB color value code of each pixel point of the foreground color layer may be set to (0, 0), or the color value code of each pixel point of the foreground color layer may be set to #000000 according to a hexadecimal color table.

Alternatively, the foreground color of the second view may be null, or the foreground color layer may not be drawn when the second view is drawn, by setting the foreground color layer to a null value (for example, null). The implementation manner of the terminal device to draw the second view may be as follows:

in one possible implementation, the terminal device draws a background layer of the first view first, draws a layer corresponding to the screen display element of the message screen, and draws an empty foreground layer.

In another possible implementation manner, the terminal device draws a background layer of the first view first, and draws a layer corresponding to the screen display element.

With reference to the first aspect, in some implementations of the first aspect, switching the screen state of the terminal device from the on-screen state to the off-screen state includes: the battery management service module sends a first screen state switching request to the layer management service module, wherein the first screen state switching request is used for requesting to switch the screen state of the terminal equipment from a bright screen state to a dead screen state; the layer combination service module sends a first screen state switching request to the display frame module and the display driver respectively; the display frame module and the display driver respectively switch the screen state of the terminal equipment from a bright screen state to a screen-off state; when the battery management service module monitors that the screen state in the display frame module is switched to the off-screen state, a power-down request is sent to the display driver; the display driver performs a power-down operation of the display screen based on the power-down request.

With reference to the first aspect, in certain implementations of the first aspect, drawing the first view based on the first window layout parameter includes: the battery management service module adjusts the information screen display service through the information screen display application; the screen-extinguishing display application transmits a second window layout parameter to the window management service module; the window management service module transmits a first drawing request to the screen-extinguishing display application, wherein the first drawing request carries a first window layout parameter; the screen-extinguishing display application draws a first view based on the first window layout parameters; adjusting the first window layout parameter to a second window layout parameter, comprising: the window management service module adjusts the first window layout parameters to second window layout parameters; drawing a second view based on a second window layout parameter, comprising: the window management service module transmits a second drawing request to the screen-extinguishing display application, wherein the second drawing request carries second window layout parameters; the off-screen display application draws a second view based on the second window layout parameters.

With reference to the first aspect, in certain implementation manners of the first aspect, before drawing the first view, the method further includes: the screen-extinguishing display application determines that the current screen direction of the terminal equipment is the horizontal screen direction based on the width and the height of the window.

The power-on request is repeatedly sent to the display driving module, so that the problem that a screen display interface of a screen can not be displayed due to power-on failure caused when the screen state of the display frame module is successfully switched and the screen state of the display driving is not successfully switched is solved, and the stability of the screen display of the terminal equipment is improved.

With reference to the first aspect, in certain implementation manners of the first aspect, the method further includes: the battery management service module judges whether the repeated sending times of the power-on request are equal to a preset upper limit value or not; repeating the sending of the power-on request to the display driver a plurality of times, comprising: and under the condition that the repeated sending times of the power-on request are smaller than the preset upper limit value, the battery management service module repeatedly sends the power-on request for a plurality of times.

It should be understood that, when the number of repeated sending times of the power-on request is greater than the preset upper limit value and the power-on fails, the battery management service module reports the abnormal power-on. The power-on anomaly may be obtained through a code log.

By setting the preset upper limit value, the problem that the power-on current process enters the dead loop when the power-on failure of the display drive is caused by other faults can be solved.

However, since the window management service module in the terminal device adjusts the layout parameters, the drawing of the view is not sequentially performed with the triggering of the off-screen display application in the terminal device by the window management service module in the terminal device, it may occur that the off-screen display application in the terminal device has already started drawing the view after being triggered, and the window management service module layout parameters in the terminal device have not been adjusted. Therefore, the terminal equipment can display a screen-extinguishing display interface of a frame of horizontal screen, then display a screen-extinguishing display interface of a vertical screen, and abnormal display scenes are caused to the terminal equipment, namely, the phenomenon of flashing frequency is generated when the screen-extinguishing display interface is displayed, so that the user experience is poor.

The display interface of the related art will be described below by taking the example that the terminal device is a mobile phone.

Exemplary, fig. 3 shows a diagram of a change of a screen-extinguishing display interface of a mobile phone in a horizontal screen state. In the interface a shown in fig. 3, the interface displays a plurality of application icons, i.e., the interface is in an awake state. The user presses the power key of the mobile phone, the mobile phone responds to the pressing operation of the user, the interface displays the interface b shown in fig. 3, and then the interface d shown in fig. 3 is displayed after the interface flashes the interface c shown in fig. 3. The interface b shown in fig. 3 is an off-screen interface, and the interface does not display any content. In the interface c shown in fig. 3, the time information "11:34 months 29 days, monday, twelve earthly branches, forty-one year", is displayed in the middle of the interface, and the battery icon and the battery power information "50%" are displayed below the time information. The directions of the time information, the battery icon and the battery electric quantity information are adapted to the horizontal screen direction of the mobile phone, namely, the directions are displayed through the horizontal screen. In the interface d shown in fig. 3, the time information "11:34 months 29 days, monday, twelve earthly branches, forty-one year", is displayed in the middle of the interface, and the battery icon and the battery power information "50%" are displayed below the time information. The directions of the time information, the battery icon and the battery electric quantity information are adapted to the vertical screen direction of the mobile phone, namely, the display is performed through the vertical screen.

The interface c and the interface d in fig. 3 are all screen display interfaces. The interface c can flash when the mobile phone displays the screen-extinguishing display interface in a horizontal screen state, namely, the screen-flashing phenomenon is generated, and the user experience is poor.

Therefore, in the case that the screen-extinguishing display is required and the current screen direction of the terminal device is the horizontal screen direction, by drawing and displaying the first view with the black foreground color, if the terminal device completes the adjustment of the layout parameters after the window management service module triggers the screen-extinguishing display application drawing, the terminal device can display the first view, that is, the user cannot see the screen-extinguishing display interface of the horizontal screen, and after the window management service module completes the adjustment of the layout parameters, drawing and displaying the second view (the view corresponding to the screen-extinguishing display interface and with the empty foreground color) based on the adjusted window. Therefore, the drawing of the view can be started after the screen-extinguishing display application in the terminal equipment is triggered, and under the condition that the layout parameters of the window management service module in the terminal equipment are not adjusted, the screen-extinguishing display interface of the transverse screen is prevented from being displayed, so that abnormal display scenes of the screen-flashing occur, and the user experience is improved.

In the following, an interface change chart of the screen-extinguishing display method provided in the embodiment of the present application is described by taking a mobile phone as an example of a terminal device.

Fig. 4 shows a diagram of still another screen-extinguishing display interface change of the mobile phone in a horizontal screen state. In the interface a shown in fig. 4, the interface displays a plurality of application icons, i.e., the interface is in an awake state. The user presses the power key of the mobile phone, and the mobile phone responds to the pressing operation of the user, and the interface displays the interface b of fig. 4, and then the interface b is changed into the interface c of fig. 4. Interface b of fig. 4 does not display anything. In the interface c shown in fig. 4, the time information "11:34 months 29 days, monday, twelve earthly branches, forty-one year", is displayed in the middle of the interface, and the battery icon and the battery power information "50%" are displayed below the time information. The directions of the time information, the battery icon and the battery electric quantity information are adapted to the vertical screen direction of the mobile phone, namely, the display is performed through the vertical screen.

And in the transverse screen mode, the terminal equipment responds to the pressing operation of the power key by the user and displays a screen-extinguishing display interface. Interface change is: and the display interface is excessively changed from the bright screen to the off screen. The phenomenon of screen flashing when the terminal equipment enters the screen-extinguishing display interface in the horizontal screen state is avoided, and the user experience is improved.

In this embodiment of the present application, the terminal device starts view drawing before adjusting the window layout parameters, where the window layout parameters acquired by the terminal device before drawing are first window layout parameters (i.e., window layout parameters in which the screen direction is the horizontal screen direction), and the terminal device may draw the first view based on the first window layout parameters. In addition, the terminal device adjusts the first window layout parameter to a second window layout parameter, and draws the second view.

In the method 500, S502 includes a process of drawing the first view, and S504 includes a process of adjusting parameters and drawing the second view. The terminal device may perform S502 and S504 simultaneously, and the terminal device may perform S502 and then S504, which is not limited in this application.

After drawing the view, the terminal device triggers the display screen to power up and displays the corresponding interface. When the terminal device is powered on, the second view is not drawn yet, and the terminal device will display the first view first and then display the second view. At this time, the method 500 may be executed in the order of S501 to S505, or S502 and S504 may be executed simultaneously. The display interface change sequence of the terminal equipment is as follows: bright screen interface-off screen interface-first view interface-second view interface.

In another possible implementation manner, the terminal device finishes drawing the first view first and then finishes drawing the second view. After drawing the view, the terminal device triggers the display screen to power up and displays the corresponding interface. When the terminal device is powered on, the second view is drawn, and the terminal device does not display the first view and directly displays the second view. In this case, after the execution of S504 is completed, the terminal device then executes the screen state switching in S503, but does not display the first view, and directly displays the second view. The display interface change sequence of the terminal equipment is as follows: bright screen interface-off screen interface-second view interface.

In yet another possible implementation, the terminal device does not perform S502 nor the displaying of the first view in S503. That is, after the terminal apparatus performs the completion S501, S504 is then performed, and after the completion S504 is performed, the screen state switching in S503 is then performed, but the first view is not displayed, and S505 is then performed. The terminal equipment starts drawing the view after adjusting the window layout parameters, the window layout parameters acquired by the terminal equipment before drawing are second window layout parameters (namely window layout parameters in the vertical screen direction), the terminal equipment can draw a second view based on the second window layout parameters, after the second view is drawn, the screen state is switched from the screen-off state to the screen-off display state, the power on of the display screen is triggered, and the second view is displayed.

Fig. 7 is a schematic diagram of switching between four screen states of a terminal device. Under the condition that the terminal equipment starts the AOD function, the display screen of the terminal equipment comprises four states which are respectively: a bright screen state (may be abbreviated as an on state), a dead screen state (may be abbreviated as an off state), a dead screen display state (may be abbreviated as a doze state), and a dead screen display pause state (may be abbreviated as a doze_supply state). The on state, the off state, the doze state, the doze_supported state, and the like are merely exemplary, and the four screen states are not limited in the present application.

When the display screen is in an on state, the display screen is electrified, and a user can see a picture displayed on the display screen. And when the display screen is in an off state, the display screen is not electrified. And when the display screen is in the doze state, the display screen is locally electrified, the screen displays a screen-extinguishing display interface, and the AP is in an active state. For example, in this state, when the screen-extinguishing display interface includes an animation style, the animation can be normally played. And when the display screen is in the doze_supported state, the local part on the screen is electrified, the screen displays a screen-extinguishing display interface, and the AP is in the dormant state. For example, in this state, when the screen-off display interface includes an animation style, the interface displays a certain frame of still picture of the animation.

The switching of the different states includes the following four cases.

In case 1, the screen state of the terminal device is in the on state.

Under the condition that the AOD is not started, the terminal equipment detects that the operation of the user is not accepted within the preset time or the terminal equipment detects the pressing operation of the power key by the user, and the terminal equipment controls the screen state to be switched into the off state.

In case 2, the screen state of the terminal device is in an off state.

The terminal device detects the pressing operation of the power key by the user, and controls the screen state to be switched to the on state. In a possible scenario where the AOD is on, the terminal device detects a touch operation of the user on the screen, and the terminal device controls the screen state to switch to the doze state. In another possible scenario, the terminal device detects that the operation of the user is not accepted within a preset time or the terminal device detects that the pressing operation of the power key by the user, and the terminal device controls the screen state to switch to the doze state.

In case 3, the screen state of the terminal device is in the doze state.

The terminal equipment detects double-click operation of a user on the screen or detects pressing operation of the user on a power key, and the terminal equipment controls the screen state to be switched to an on state. In one possible scenario, the user does not set the AOD mode to be the all-day mode, the terminal device does not continue to display the screen-extinguishing display interface after displaying the screen-extinguishing display interface for a preset time, and the terminal device controls the screen state to switch to the off state. In another possible scenario, the terminal device detects that the user opens the AOD all-day mode, and after displaying the rest screen display interface for a preset time, the terminal device does not display the animation in the rest screen display interface (if the rest screen display interface does not include the animation, the rest screen display interface does not change), and the terminal device controls the screen state to switch to the doze_supply state.

In case 4, the screen state of the terminal device is in the doze_supported state.

The terminal device detects the pressing operation of the power key by the user, and controls the screen state to be switched to the on state. The terminal equipment detects the touch of the user on the screen, or detects the mobile operation of the user on the mobile phone, or the signal of AOD display information updating, and controls the screen state to be switched to the doze state.

In the following, taking an example that the terminal device displays a screen-extinguishing display interface after the user presses the power key of the terminal device, the internal interaction process of the terminal device is described in detail.

Fig. 8 is a schematic flowchart of a screen-off display method 800 according to an embodiment of the present application. The hardware structure of the terminal device involved in the method 800 may be shown in fig. 2, and the software structure may be shown in fig. 3.

S801, in response to the pressing operation of the power key by the user, the kernel layer transmits the pressing data corresponding to the pressing operation to the input management service module, and correspondingly, the input management service module obtains the pressing data.

It should be appreciated that the power key sending the press data to the input management service module through the kernel layer may also be referred to as the power key reporting the press event to the input management service module through the kernel layer.

Specifically, the above-mentioned pressing data may include a key identification and a key type of the power key. Wherein, the key identification can be a key ID or a key name. The key types may include a short press type and a long press type.

It should also be understood that the keys on the terminal device include other keys in addition to the power key, such as a volume up key and a volume down key. Different keys correspond to different key identification information.

Optionally, the pressing operation corresponds to the following actions: the key is pressed first and then lifted, and the corresponding state bit change information is as follows: first pressed and then lifted. And determining that the key type is a short-press type under the condition that the time interval from pressing to lifting of the status bit of the key is smaller than or equal to a preset threshold value. And under the condition that the time interval from pressing to lifting of the state bit of the key is larger than a preset threshold value, determining that the key type is a long-press type.

Illustratively, the key identification of the power key may be "id=26". The time interval from pressing to lifting of the status bit of the key of the power key is 150ms, and the preset threshold is 200ms.150ms is less than a preset threshold of 200ms. The power key determines that the key type is a short press type.

S802, the input management service module transmits the pressing data to the battery management service module. Correspondingly, the battery management service module obtains the pressing data.

S803, based on the pressing data and the screen state, the battery management service module determines whether the screen state needs to be switched to the off-screen state.

Alternatively, before the pressing operation, the screen state may include four states of a bright screen state, a dead screen display state, and a dead screen display pause. The press data may include both a long press of the power key and a short press of the power key. The battery management service module judges what state the screen state is switched to based on the pressing data and the screen state includes the following cases.

In case 1, when the screen state is any one of a bright screen state, a dead screen display state, and a dead screen display pause state, and the pressing data is a long press type of a power key, the battery management service module determines that the subsequent terminal device is about to execute shutdown, and the display screen displays a shutdown selection interface, wherein the shutdown selection interface comprises a selection button for restarting or shutdown so as to be convenient for a user to select.

In case 2, when the screen state is any one of the off-screen state, the off-screen display state, and the off-screen display pause state, and the pressing data is a short press type of the power key, the battery management service module determines that the screen state needs to be switched to the on-screen state.

In case 3, when the screen state is the bright screen state and the pressing data is the short press type of the power key, the battery management service module determines that the screen state needs to be switched to the off screen state.

That is, in case 3, the battery management service module determines that the screen state needs to be switched to the off-screen state, and in case 1 or case 2, the battery management service module determines that the screen state does not need to be switched to the off-screen state.

S804, when the battery management service module determines that the screen state needs to be switched to the off-screen state, the battery management service module transmits a first screen state switching request to the layer combination service module, and correspondingly, the layer combination service module obtains the first screen state switching request.

It should be appreciated that the first screen state switching request is for switching the screen state from the on-screen state to the off-screen state.

After S804, S805 and S806 are performed simultaneously by the layer service module.

S805, the layer combination service module transmits a first screen state switching request to the display frame module, and correspondingly, the display frame module obtains the first screen state switching request.

S806, the layer combination service module transmits a first screen state switching request to the display driving module, and correspondingly, the display driving module obtains the first screen state switching request.

S807 is performed after S805, and S808 is performed after S806.

S807, the display frame module updates the screen state stored in the display frame module to the off-screen state.

S808, the display driving module updates the screen state saved in the display driving to the off-screen state.

Alternatively, the display driving module may update the screen state to the off-screen state by adjusting the screen refresh rate and the screen maximum brightness value.

It should be appreciated that different screen states correspond to different screen refresh rates and screen maximum brightness values.

S809, the battery management service module monitors whether the screen state stored by the display frame module is updated to the off-screen state.

S810, when the screen state stored in the display frame module is updated to the off-screen state, the battery management service module requests power-down to the display driving module.

S811, the display driving module executes power-down operation.

S812, based on the pressing data and the screen state change, the battery management service module judges whether the screen display service needs to be adjusted.

It should be understood that the screen state change means that the screen is switched from one of the four states to the other state within a preset time. For example, the screen is switched from the bright screen state to the off screen state within 200 ms.

Optionally, the battery management service module determines that the rest screen display service needs to be adjusted when the pressing data is of a short press type of the power key and the screen state is switched from the bright screen state to the off screen state within a preset time. Otherwise, the battery management service module determines that the rest screen display service does not need to be tuned.

S813, in the case where the battery management service module determines that the screen display needs to be adjusted, the battery management service module adjusts the service of the screen display application.

It will be appreciated that the services of the call-up screen display application may cause the call-up screen display application to perform subsequent call-up screen display related steps.

Illustratively, the battery management service module invokes the services of the message screen display application through the streamcontroller class.

Optionally, S814, the off-screen display application determines whether off-screen display can be performed.

Alternatively, in a case where the off-screen display function is turned on, the off-screen display application may be configured not to perform the off-screen display under a preset condition. The preset condition may be any one of the following conditions: the power of the terminal device is lower than a preset value and the terminal device detects the proximity light. And under the condition that the preset condition is met, the screen-extinguishing display application determines to execute screen-extinguishing display. And under the condition that the preset condition is not met, the screen-extinguishing display application determines that the screen-extinguishing display is not executed.

Illustratively, the off-screen display application determines to perform the off-screen display in the event that the power of the terminal device is less than 10%. As another example, in the case where the screen of the terminal device is blocked. The off-screen display application determines not to execute the off-screen display.

Optionally, S815, the off-screen display application determines whether the screen form is a folded-screen unfolded state.

In particular, the terminal device may comprise a straight panel terminal device and a foldable terminal device. The unfolded state of the folding screen means that the screen form of the foldable terminal device is in a non-fully folded state. When the display screen is the display screen of the straight panel terminal equipment or the display screen is the outer display screen when the foldable terminal equipment is in the completely folded state, the screen form of the display screen of the terminal equipment is determined not to be in the unfolded state of the folding screen.

The terminal device is a mobile phone, and the mobile phone comprises a board straightening machine and a folding screen mobile phone. And determining that the screen form is not in the folded screen unfolding state under the condition that the screen is a display screen of the straight-plate mobile phone or an external display screen when the folded-screen mobile phone is in the fully folded state.

S816, under the condition that the screen form is not the folded screen unfolding state, the screen extinguishing display application transmits the screen extinguishing display view and default window layout parameters to the window management service module, wherein the screen direction parameter in the default window layout parameters is a first parameter, and the first parameter indicates that the screen direction is the vertical screen direction.

It should be appreciated that the off-screen display view includes at least one sub-view. For example, the at least one sub-view may be one or more of a date field word sub-view, an animated sub-view, a background sub-view, etc.

It should also be understood that the screen direction parameter in the default window layout parameter is set by the developer for the terminal device to display the screen-in-screen display interface based on the screen direction parameter in the default window layout parameter. And the terminal equipment displays a vertical screen information display interface based on the screen direction parameter in the default window layout parameters.

Alternatively, the default window layout parameters may include the size of the window, the layout manner of the window (whether full screen layout is performed), whether the window is responsive to a touch signal, and the like. For example, the size of the window may be the same as the screen size, the layout of the window may be a full screen layout (i.e., the interface does not display a status bar), and the interface corresponding to the window may not respond to a touch operation by the user. A window may be understood as a container carrying a view.

Alternatively, the first parameter may be represented by a numerical value. For example, a first parameter of 1 indicates that the screen direction is the portrait direction.

It should be appreciated that in the case where the screen modality is the folded screen expanded state, the off-screen display application communicates the off-screen display view and a default window layout parameter to the window management service module, where the screen direction parameter in the default window layout parameter may be a third parameter indicating that the screen direction follows the direction of the terminal device. Or in the case that the terminal device is in a folded screen unfolded state, the default window layout parameters transferred to the window management service module by the off-screen display application do not include screen direction parameters.

Illustratively, the off-screen display application may communicate the off-screen display view and the default window layout parameters to the window management service module by invoking an add-view function through the window management interface. The window management interface may be a WindowManager interface, and the add view function may be an addView function.

S817 described below may be performed after S816, or S832 may be performed simultaneously.

S817, the window management service module transmits a first drawing request to the screen-in display application, where the first drawing request carries a window layout parameter of the current screen.

It should be appreciated that the first drawing request is used to instruct the message display application to execute a flow of drawing the view. The first drawing request may also be referred to as a triggering request, i.e. the window management service module triggers the off-screen display application to draw the off-screen display view.

Specifically, the window layout parameters of the current screen may include the width and height of the current window.

S818, the off-screen display application judges whether black foreground color is needed to be drawn for the off-screen display view.

Optionally, the off-screen display application compares the width and height of the current window. In the case of a width greater than height, the off-screen display application determines to draw a black foreground color for the off-screen display view.

It should be appreciated that the current window may also be referred to as a canvas on which the message screen display view is drawn.

And S819, in the case that the off-screen display application needs to draw a black foreground color for the off-screen display view, drawing a first view with the black foreground color by the off-screen display application.

It will be appreciated that the off-screen display application draws the first view from the resulting widths and heights described above.

Specifically, the process of drawing the first view may be: firstly, drawing a view background layer, then drawing a layer corresponding to a screen display element of the screen, and finally drawing a black foreground color layer.

It should also be appreciated that where the off-screen display application does not need to draw a black foreground color for the off-screen display view, the off-screen display application draws a second view that does not include a black foreground color.

Alternatively, the process of drawing the second view may be: firstly, drawing a view background layer, and then drawing a layer corresponding to a screen-extinguishing display style.

S820, the screen-off display application notifies the battery management service module that the drawing of the view is completed.

S821, the battery management service module transmits a second screen state switching request to the layer combination service module, and correspondingly, the layer combination service module obtains the second screen state switching request.

It should be appreciated that the second screen state switching request is for switching the screen state from the off-screen state to the off-screen display state. I.e. the screen state is switched from off to doze.

After S821, the layer service module performs S822 and S823 simultaneously.

S822, the layer combination service module transmits a second screen state switching request to the display frame module, and correspondingly, the display frame module obtains the second screen state switching request.

S823, the layer combination service module transmits a second screen state switching request to the display driving module, and correspondingly, the display driving module obtains the second screen state switching request.

S824 is performed after S822, and S825 is performed after S823.

S824, the display frame module updates the screen state stored in the display frame module to a screen-off display state.

S825, the display driver module updates the screen state saved in the display driver to a screen-off display state.

S826, the screen-off display application monitors whether the screen state stored by the display framework module is updated to the screen-off state.

S827, when the screen state stored in the display frame module is updated to the screen-off state, the screen-off display application transmits a backlight-off instruction to the battery management service module, wherein the backlight-off instruction carries screen brightness information, and correspondingly, the battery management service module obtains the backlight-off instruction.

Optionally, the off-screen display application determines screen brightness information according to the ambient brightness and communicates the screen brightness information to the battery management service module.

S828, the battery management service module requests power up to the display driving module based on the backlight down instruction.

S829, the display driving module executes a power-on operation based on the backlight command.

It should be understood that the power-up operation may also be understood as controlling the screen lighting by the display driving module. Powering up may also be understood as setting a backlight.

In one possible case, the above-mentioned S824 is completed faster than S825. That is, the screen state stored in the display frame module is updated to the idle screen display state, and the screen state stored in the display driving module is not updated to the idle screen display state. This may result in the display driving module performing power-up failure in S829. After S829 fails to power up, the steps S828 to S829 continue to be cyclically executed until the power up of the display driving module is successful.

And S830, after the power-on of the display driving module is successful, notifying the battery management service module of finishing the power-on.

S831, the off-screen display application displays the first view.

S832, the window service management module judges whether the screen direction parameter in the default window layout parameter is the same as the screen direction parameter in the window layout parameter of the current screen.

It should be understood that the screen direction may include a horizontal screen direction or a vertical screen direction, and that the corresponding screen direction parameter may be a second parameter when the screen direction is the horizontal screen direction and the corresponding screen direction parameter may be a first parameter when the screen direction is the vertical screen direction. In the case that the screen direction parameter in the window layout parameters of the current screen is the second parameter, the window service management module determines that the screen direction parameter in the default window layout parameters is different from the screen direction parameter in the window layout parameters of the current screen. In the case that the screen direction parameter in the window layout parameters of the current screen is the first parameter, the window service management module determines that the screen direction parameter in the default window layout parameters is the same as the screen direction parameter in the window layout parameters of the current screen.

S833, when the screen direction parameter in the default window layout parameter is different from the screen direction parameter in the window layout parameter of the current screen, the window service management module adjusts the screen direction parameter in the window layout parameter of the current screen to be the first parameter, and the adjusted window layout parameter is obtained.

It should be understood that the screen direction parameter in the window layout parameters of the current screen is adjusted to the first parameter, that is, the window direction of the current screen is adjusted to the vertical screen direction.

It should also be appreciated that in the case where the screen direction parameter in the default window layout parameter is the same as the screen direction parameter in the window layout parameter of the current screen, the window service management module does not need to make parameter adjustments nor draw the second view.

S834, the window service management module transmits a second drawing request to the screen-extinguishing display application, wherein the second drawing request carries the adjusted window layout parameters.

It should be understood that the window layout parameters after adjustment are window layout parameters in the vertical screen direction.

It should also be appreciated that the second drawing request is for instructing the message display application to perform drawing of the second view. The second drawing request may also be referred to as a trigger request, i.e. the window management service module triggers the off-screen display application drawing view.

S835, the off-screen display application draws the second view based on the adjusted window layout parameters.

Specifically, the off-screen display application is based on the adjusted window width and Gao Huizhi second view.

Optionally, drawing the second view may include a variety of implementations.

In one possible implementation, the off-screen display application updates the first view according to the width and height of the adjusted window, and deletes the black foreground color layer in the first view to obtain the second view.

In another possible implementation, the off-screen display application first draws a view background layer according to the width and height of the adjusted window, and then draws a layer corresponding to the off-screen display style.

S836, the second view is displayed.

In the method 800, S817 to S819 are flows for drawing the first view, and S832 to S835 are flows for drawing the second view. The terminal device may perform S817 to S819 and S832 to S835 simultaneously. The terminal device may perform the completion of S817 to S819 first and then perform the completion of S832 to S835, which is not limited in this application.

Embodiments of the present application include the following many possible implementations:

mode 1, a terminal device draws and displays a first view and a second view.

The terminal equipment firstly completes drawing of the first view and then completes drawing of the second view. After drawing the view, the terminal device triggers the display screen to power up and displays the corresponding interface. When the terminal device is powered on, the second view is not drawn yet, and the terminal device will display the first view first and then display the second view. That is, after executing S816, the terminal device executes the completion S817 to S819, then executes the completion S832 to S835, and S835 is completed after S829, and after powering on the display driver, the terminal device displays the first view and then displays the second view.

In this implementation, the interface display of the terminal device changes to: bright screen interface-off screen interface-first view interface-second view interface.

In mode 2, the terminal device draws the first view and the second view, and does not display the first view, but only displays the second view.

The terminal equipment firstly completes drawing of the first view and then completes drawing of the second view. After drawing the view, the terminal device triggers the display screen to power up and displays the corresponding interface. When the terminal device is powered on, the second view is drawn, and the terminal device does not display the first view and directly displays the second view. That is, after executing S816, the terminal device executes the completion S817 to S819, then executes the completion S832 to S835, and S835 is completed before S829, and after powering up the display driver, the terminal device does not display the first view and directly displays the second view.

In this implementation manner, the display interface change sequence of the terminal device is: bright screen interface-off screen interface-second view interface.

Mode 3, the terminal device draws the second view and displays the second view.

The terminal device does not execute the flow of drawing and displaying the first view. The terminal equipment starts view drawing after adjusting window layout parameters, the window layout parameters acquired by the terminal equipment before drawing are second window layout parameters (namely window layout parameters in the vertical screen direction), the terminal equipment can draw a second view based on the second window layout parameters, after the second view drawing is completed, the screen state is switched from the screen-off state to the screen-off display state, the power on of the display screen is triggered, and the second view is displayed. That is, after executing S816, the terminal device executes S832 to S835, then executes S820 to S830, and finally executes S836.
