In some embodiments, both displays may be controlled by a single overall controller, and in this case, a single controller is configured in the display device to form a dual-screen single-system display device. The controller is in communication connection with the first display and the second display respectively, and content display of the two displays is achieved.

In some embodiments, the two displays may be respectively controlled by corresponding controllers, and at this time, the two controllers, namely the first controller and the second controller, are configured in the display device, so as to form a dual-screen dual-system display device. A first hardware system is configured in the first controller and is a main chip; and a second hardware system is configured in the second controller and is an auxiliary chip.

The first controller is connected with the first display, and the second controller is connected with the second display. The first controller controls the display of each content in the first display and sends a broadcast to the second controller to inform the second controller to control the second display to display the content. When a user operates the display device to generate a message or the device itself generates a message, the first controller sends the message to be presented in the second display to the second controller, so that the second controller presents the message in the second display.

When the double screens of the display device are used for content display, the brightness of the main screen can be directly adjusted generally, and the brightness of the auxiliary screen cannot be adjusted due to the limitation of system hardware, so that the user experience is influenced.

Therefore, in order to implement brightness adjustment of the secondary screen of the display device, embodiments of the present invention provide a display device, which implements cross-screen brightness adjustment by adjusting the brightness of the secondary screen (second display) through a UI on the primary screen (first display); and a UI interface is added to the sub-screen to simulate the brightness change in order to visually check the brightness change. Meanwhile, according to the use scene, the brightness of the auxiliary screen can be automatically adjusted, the effect of not disturbing a user to watch the content of the large screen is achieved, and the functions of brightness adjustment and automatic adjustment of the auxiliary screen can be further achieved.

In the double-screen display device, a small screen is added below or above a large screen of the display device, and for adjusting the brightness of the auxiliary screen, the user-defined brightness of the auxiliary screen needs to be supported, and how to automatically control the brightness needs to be considered. For this reason, based on this idea, the present application has two functions for the luminance of the sub-screen: supporting a user to automatically adjust the brightness of the auxiliary screen through a setting menu; when the auxiliary screen does not have any interaction and push, the brightness is automatically reduced after a period of time, namely the auxiliary screen and the display device base are integrated into a whole in appearance, and the user cannot be disturbed when the user operates the large-screen content of the display device.

FIG. 7(a) is an overall logic diagram illustrating a prior art secondary screen brightness adjustment according to some embodiments; FIG. 7(b) illustrates another overall logic diagram for prior secondary screen brightness adjustment according to some embodiments. Referring to fig. 7(a), when user-defined sub-screen brightness is achieved, for a dual-system display device, a first controller and a second controller configured in the display device achieve communication through an RPC communication protocol, a setting module and a Flow interface are configured in the first controller, the setting module is a system service (system service) achieved by a brightness adjustment function, and the Flow interface can obtain a sub-screen brightness value defined based on the first display. At the moment, a setting module in the first controller calls a Flow interface to obtain an auxiliary screen brightness value set by a user, the auxiliary screen brightness value is sent to the second controller through an RPC communication protocol, and the brightness of the second display is adjusted by a conversion service configured in the second controller according to the auxiliary screen brightness value, so that the auxiliary screen brightness is changed.

Referring to fig. 7(b), when the disturbance-free mode is realized, the setting module in the first controller notifies the second controller based on the RPC communication protocol, the second controller notifies the Home (Home) of the secondary screen, the Home timing is finished, the setting module is notified through the RPC, and then the setting module sets the conversion service configured in the second controller through the RPC call flow interface to call the disturbance-free interface, so that the brightness of the secondary screen is automatically reduced when the Home of the secondary screen is not interacted within a period of time, and the secondary screen enters a screen-saving state.

The auxiliary screen brightness can not be adjusted by all models of display equipment, namely, the auxiliary screen brightness interface is called by part of models of display equipment to be ineffective. Therefore, in order to realize that the brightness of the auxiliary screen can be adjusted by the display equipment of all models, the brightness of the auxiliary screen is adjusted by the display equipment provided by the embodiment of the invention in a simulation mode according to the following scheme.

When the auxiliary screen brightness adjustment is realized, the display device provided by the application keeps default set screen brightness (brightness adjustment mode) and disturbance-free logic (disturbance-free mode), meanwhile, the auxiliary screen brightness service is configured in the second controller, namely the conversion service is changed into the auxiliary screen brightness service, and the auxiliary screen brightness service is used for realizing the brightness adjustment of the auxiliary screen.

FIG. 8(a) is a schematic diagram illustrating the overall logic of the secondary screen brightness adjustment of the present application according to some embodiments; FIG. 8(b) shows another overall logic diagram for the secondary screen brightness adjustment of the present application, according to some embodiments. Referring to fig. 8(a), for the dual-system display device, when the auxiliary screen brightness is adjusted by a user, the second controller calls the Flow interface in the first controller, and simultaneously calls the auxiliary screen brightness service interface, that is, the set mode in the first controller directly performs RPC communication with the auxiliary screen brightness service in the second controller, and the auxiliary screen brightness service adjusts the auxiliary screen brightness according to the obtained user-defined brightness value. Referring to fig. 8(b), when the disturbance-free mode is realized to adjust the brightness of the secondary screen, the setting module in the first controller notifies the second controller based on the RPC communication protocol, the second controller notifies the Home (Home page) of the secondary screen, the Home timing is ended by notifying the setting module through the RPC, and then the setting module sets the brightness service of the secondary screen configured in the second controller through the RPC call flow interface, so that the secondary screen enters the disturbance-free mode.

For single-system display equipment, when the auxiliary screen brightness is adjusted in a user-defined mode, an auxiliary screen brightness service interface is configured in the general controller and can be directly called to start the auxiliary screen brightness service, and the auxiliary screen brightness service adjusts the auxiliary screen brightness through the acquired user-defined brightness value. When the auxiliary screen brightness is adjusted in the non-disturbing mode, a setting module in the controller informs an auxiliary screen Home (homepage), the Home timing is finished by informing the setting module through RPC, and then the setting module calls the auxiliary screen brightness service through RPC to realize that the auxiliary screen enters the non-disturbing mode.

The activation of the secondary screen brightness service configured in the master controller in a single system or the second controller in a dual system is initiated by the device module (systemService): and after the display equipment is started, starting the system service, and further triggering the starting of the auxiliary screen brightness service by the system service. In order to make the secondary screen present the brightness change in visual effect when adjusting the brightness, a window mask (highest level) is started in the second display by the secondary screen brightness service, the background transparency of the mask is divided into 15 equal parts from 0 to 170, and the brightness change is indirectly simulated by adjusting the background transparency.

The window mask is a window mask layer having the highest priority of presentation order, i.e., being presented on an upper layer of the second user interface, i.e., overlaid on the second user interface, after being activated. The window shielding layer is in a transparent form, and shielding of the second user interface in different degrees is achieved by setting the background transparency of the window shielding layer, so that the change of the brightness of the auxiliary screen is simulated.

The internal logic of the brightness adjustment of the auxiliary screen brightness service is that the auxiliary screen brightness value of the Flow layer is called through an RPC communication protocol, the auxiliary screen brightness value is converted into a target background transparency, and then the background transparency of the window mask layer is adjusted based on the target background transparency, so that the auxiliary screen brightness is adjusted.

FIG. 9 illustrates a first flow chart of a secondary screen brightness adjustment method according to some embodiments; FIG. 10 illustrates a data flow diagram of a secondary screen brightness adjustment method according to some embodiments. In order to implement the above-mentioned sub-screen brightness adjustment logic, an embodiment of the present invention provides a display device, which is applied to a display device of a dual-screen single system, and includes: a first display configured to present a first user interface; a second display configured to present a second user interface; controller connected to the first display and the second display when the sub-screen brightness adjustment method shown in fig. 9 and 10 is performed, the controller is configured to perform the following steps:

s11, responding to a start-up instruction triggered by a user, acquiring a default brightness value of the second display, and displaying a window mask layer on an upper layer of the second display based on the default background transparency corresponding to the default brightness value.

When the display device is started, a user triggers a power key of the display device to execute a power-on action, wherein the power key can be a power key configured on a remote controller of the display device or a power key configured on the display device. And a user triggers a power key to generate a starting-up starting instruction, a controller of the display equipment executes a starting-up action, simultaneously starts an auxiliary screen brightness service configured in the controller, and presents a window mask layer in the second display through the auxiliary screen brightness service.

After the display equipment is started, the controller receives a starting-up instruction, and obtains a default brightness value of the second display while displaying the second user interface in the second display.

In some embodiments, the highest brightness value of the second display may be set to 15 and the default brightness value may be set to 12. The maximum background transparency of the window mask layer is 170, and thus, to achieve a correspondence of luminance values to background transparency, the background transparency may be divided into 15 equal parts from 0 to 170. For each increase of the brightness value by one value, the background transparency is increased by about 12 values, for example, when the brightness value of the auxiliary screen is 0, the background transparency is 0; when the brightness value of the auxiliary screen is 1, the background transparency is 12; when the brightness value of the auxiliary screen is 2, the background transparency is 24; and so on, at a sub-screen brightness value of 15, the background transparency is 170. Therefore, when the user customizes the brightness value of the auxiliary screen in the first display, the brightness change can be indirectly simulated in the second display by adjusting the transparency of the background.

Based on the above, when the mobile terminal is started, the second controller calls the auxiliary screen brightness service to acquire the default brightness value of the second display, and determines the default background transparency corresponding to the default brightness value according to the corresponding relation between the brightness value and the background transparency. And finally, generating a window mask layer by the auxiliary screen brightness service according to the default background transparency, and displaying the window mask layer on the upper layer of the second display.

When the display device is started, the brightness of the second display is a default brightness value, and correspondingly, the window shielding layer displayed by the second display is a default background transparency and is in a normal use state, so that the brightness of the auxiliary screen is normal.

In some embodiments, the higher the background transparency value of the window mask layer, the more visually transparent, the brighter the secondary screen is characterized. Therefore, when the background transparency is defaulted, the numerical value is higher, the window mask layer is more transparent, and at the moment, the window mask layer covers the second user interface, so that the content displayed in the second user interface can be clearly seen by a user through display, and the visual effect of brighter secondary screens is presented.

In some embodiments, the smaller the background transparency value of the window mask layer, the deeper the effect of rendering the gray scale visually, the darker the representative sub-screen brightness. If the brightness value of the auxiliary screen is reduced by the user, the smaller the corresponding background transparency value is, the darker the window mask layer is, at this time, the window mask layer covers the second user interface, the content displayed in the second user interface cannot be displayed through the window mask layer, the content cannot be seen by the user or cannot be clearly seen by the user, the displayed content of the auxiliary screen is in a fuzzy state or a screen-saving state, and the darker visual effect of the auxiliary screen is presented.

S12, responding to a sub-screen brightness adjusting instruction which is triggered and sent by a user and carries a target brightness value, adjusting the default background transparency of the window mask layer to the target background transparency corresponding to the target brightness value, and adjusting the brightness of the second display through the window mask layer.

After the display equipment is started, if a user needs to adjust the brightness of the second display, a target brightness value can be generated through an auxiliary screen brightness adjusting interface presented in the first display, an auxiliary screen brightness adjusting instruction is generated at the same time, and after the controller receives the auxiliary screen brightness adjusting instruction, the auxiliary screen brightness service is called to adjust the background transparency of the window mask layer so as to adjust the auxiliary screen brightness.

In some embodiments, when the user performs the customized adjustment of the secondary screen brightness, the controller, in executing the secondary screen brightness adjustment instruction which is triggered by the user and carries the target brightness value, is further configured to perform the following steps:

and 1211, receiving an operation on a system setting control in the first user interface, and displaying a secondary screen brightness adjusting interface comprising a brightness adjusting bar in the first display.

Step 1212, receiving an operation on the brightness adjustment bar, generating a target brightness value, and generating an auxiliary screen brightness adjustment instruction based on the target brightness value.

When the user needs to self-define and adjust the brightness of the auxiliary screen, the user starts a system setting control piece through a remote controller or a voice mode. And the system setting control is displayed in the first user interface, and the user triggers the system setting control to generate an auxiliary screen brightness adjusting interface and display the auxiliary screen brightness adjusting interface in the first display.

FIG. 11 illustrates a schematic diagram of a secondary screen brightness adjustment interface, according to some embodiments. Referring to fig. 11, a brightness progress bar is displayed in the sub-screen brightness adjustment interface, and a user may drag the brightness progress bar to move to a desired brightness value, that is, to generate a target brightness value. The brightness value may be shown above the corresponding position of the brightness progress bar.

For example, when the display device is started, the window mask layer in the second display is displayed with the default background transparency, for example, the default background transparency corresponding to the default sub-screen brightness value of 12, and the sub-screen brightness effect graph is shown in fig. 11. If the user needs to increase the brightness of the auxiliary screen, a direction key right key of the remote controller can be triggered, the brightness progress bar is triggered to move rightwards, and target brightness values such as 13 and 14 are obtained. If the user needs to reduce the brightness of the auxiliary screen, a left key of a direction key of the remote controller can be triggered, a brightness progress bar is triggered to move leftwards, and target brightness values such as 11 and 10 are obtained. And adjusting the brightness value of the secondary screen once the direction key is triggered.

When the target brightness value required by the user is obtained, the auxiliary screen brightness adjusting instruction can be generated based on the target brightness value. The first controller sends the auxiliary screen brightness adjusting instruction to the second controller, and the adjustment of the background transparency of the window mask layer is achieved by calling the auxiliary screen brightness service, so that the auxiliary screen brightness adjustment is achieved.

In some embodiments, when a user needs to self-define and adjust the brightness of the auxiliary screen, the user can generate a target brightness value through an auxiliary screen brightness adjusting interface presented in the first display, and after receiving an auxiliary screen brightness adjusting instruction carrying the target brightness value, the controller can call the auxiliary screen brightness service to obtain the currently set auxiliary screen brightness value from the flow interface, that is, determine the target background transparency of the window mask layer according to the target brightness value, further adjust the original background transparency of the window mask layer to the target background transparency, and adjust the background transparency according to the target background transparency to make the auxiliary screen brightness consistent with the main screen setting. The adjusting process of the window mask layer is the brightness adjusting process of the second display.

In some embodiments, the controller is further configured to, in performing the adjusting the default background transparency of the window mask layer to a target background transparency corresponding to the target brightness value:

step 1221, if the target brightness value exceeds the default brightness value, increasing the default background transparency of the window mask layer to the target background transparency corresponding to the target brightness value to increase the brightness value of the second display.

In step 1222, if the target brightness value does not exceed the default brightness value, the default background transparency of the window mask layer is decreased to the target background transparency corresponding to the target brightness value, so as to decrease the brightness value of the second display.

When the user needs to self-define and adjust the brightness of the auxiliary screen, the user can adjust the brightness of the auxiliary screen to be lower or higher based on actual conditions, and further the brightness change of the auxiliary screen can be simulated by reducing the background transparency of the window mask layer or increasing the background transparency of the window mask layer.

When increasing the sub-screen brightness, the user may perform brightness value setting based on the sub-screen brightness adjustment interface shown in fig. 11 presented in the first display, to obtain a target brightness value. If the target brightness value is higher than the default brightness value (or the original brightness value), it indicates that the user wants to increase the brightness of the auxiliary screen. At this time, the target background transparency is determined based on the target brightness value according to the correspondence between the brightness value and the background transparency. The target background transparency is higher than the default background transparency (or original brightness value) of the window mask layer, so that the second controller calls the auxiliary screen brightness service to increase the background transparency of the window mask layer from the default background transparency (or original brightness value) to the target background transparency, so that the brightness value of the second display is increased from the default brightness value (or original brightness value) to the target brightness value, and the increase of the auxiliary screen brightness is realized.

FIG. 12 illustrates a graph of the effect of increasing the secondary screen brightness value according to some embodiments. In some embodiments, referring to fig. 12, when the sub-screen brightness value is a default brightness value of 12 and the default background transparency of the window mask layer is about 144, if the user increases to a target brightness value of 14 through the brightness progress bar in the first display, the target background transparency is determined to be about 168. If the target brightness value is higher than the default brightness value, the background transparency of the window mask layer is increased from the default background transparency 144 to the target background transparency 168, and the sub-screen brightness is increased. The background transparency is increased, the more transparent the window mask layer is, the brighter the auxiliary screen brightness is, and after the window mask layer is covered on the second user interface, the clearer the content displayed in the second user interface is seen by the user, and the clearer the content seen by the user is seen from the visual effect, the brighter the auxiliary screen is.

When the sub-screen brightness is reduced, the user may perform brightness value setting based on the sub-screen brightness adjustment interface shown in fig. 11 presented in the first display, to obtain a target brightness value. If the target brightness value is lower than the default brightness value (or the original brightness value), it indicates that the user wants to reduce the brightness of the auxiliary screen. At this time, the target background transparency is determined based on the target brightness value according to the correspondence between the brightness value and the background transparency. The target background transparency is lower than the default background transparency (or original brightness value) of the window mask layer, and therefore, the second controller calls the auxiliary screen brightness service to reduce the background transparency of the window mask layer from the default background transparency (or original brightness value) to the target background transparency, so that the brightness value of the second display is reduced from the default brightness value (or original brightness value) to the target brightness value, and the reduction of the auxiliary screen brightness is realized.

FIG. 13 illustrates a graph of the effect of reducing the brightness value of a secondary screen according to some embodiments. In some embodiments, referring to fig. 13, when the sub-screen brightness value is the default brightness value 12 and the default background transparency of the window mask layer is about 144, if the user is reduced to the target brightness value of 10 by the brightness progress bar in the first display, it is determined that the target background transparency is about 120. If the target brightness value is lower than the default brightness value, the background transparency of the window mask layer is decreased from the default background transparency 144 to the target background transparency 120, and the sub-screen brightness is decreased. The background transparency is reduced, the darker the gray level of the window mask layer is, the darker the brightness of the auxiliary screen is, after the window mask layer is covered on the second user interface, the content displayed in the second user interface is not easy to see by a user, and the more fuzzy the content seen by the user is seen from the visual effect, the more dark the auxiliary screen is.

In some embodiments, when the user adjusts the brightness of the auxiliary screen through the auxiliary screen brightness adjusting interface displayed on the main screen, only the brightness of the auxiliary screen can be correspondingly changed along with the user-defined brightness of the user, and the brightness of the main screen cannot be changed according to the user-defined brightness of the user, that is, when the content is displayed on the large screen, the user adjusts the brightness of the auxiliary screen, the content of the main screen cannot be affected, and the influence on the normal use of the user is avoided. The main screen brightness can be adjusted according to the main screen brightness adjustment self-owned logic.

Therefore, according to the display device provided by the embodiment of the invention, when the user-defined auxiliary screen brightness is executed, the user realizes the user-defined setting of the auxiliary screen brightness value based on the auxiliary screen brightness adjusting interface displayed in the first display, the controller responds to the auxiliary screen brightness adjusting instruction carrying the target brightness value, the auxiliary screen brightness service is called to obtain the user-defined target brightness value from the flow interface, the target background transparency of the window mask layer is determined according to the target brightness value, the original background transparency of the window mask layer is adjusted to the target background transparency, the background transparency is adjusted accordingly, the auxiliary screen brightness is consistent with the main screen brightness, and the adjustment of the auxiliary screen brightness is realized.

In some embodiments, the display device provided by the application can automatically adjust the brightness of the auxiliary screen through the auxiliary screen brightness adjusting interface by a user, and can automatically adjust the brightness after a period of time when the auxiliary screen is not interacted and pushed, namely, the brightness is integrated with the display device base in appearance, so that the user is not disturbed when the user operates the large-screen content of the display device.

In some embodiments, when implementing the do-not-disturb logic to adjust the sub-screen brightness, the second controller is further configured to perform the steps of:

and step 13, starting timing from the previous instruction triggered by the user, and if the next instruction is not received when the counted time length exceeds the preset time length, acquiring the current brightness value and the disturbance-free rest screen brightness value of the second display, wherein the disturbance-free rest screen brightness value is the brightness value corresponding to the second display when the second display executes the rest screen process.

And step 14, if the current brightness value exceeds the disturbance-free rest screen brightness value, reducing the current background transparency of the window mask layer to the rest screen background transparency corresponding to the disturbance-free rest screen brightness value, enabling the second display to enter a rest screen mode, and enabling the display device to enter the disturbance-free mode, wherein the current background transparency refers to the background transparency corresponding to the current brightness value.

When the user uses the dual-screen display device, the second display is used for displaying prompt messages, so that the controller can respond to the message display instruction irregularly to display the corresponding message content in the second display, and at the moment, the brightness of the second display needs to be kept in a normal default brightness state or a brightness value at which the content can be clearly seen by the user.

And if the controller does not interact with the second display any more, the controller does not send a message display instruction to the second display any more to display the secondary screen message. At this time, the sub-screen is in an unused state, the brightness of the sub-screen can be reduced, and the sub-screen enters a screen-off state, namely the sub-screen is in a dark state. Under the scene, the display equipment automatically enters the disturbance-free mode, and the brightness of the auxiliary screen is automatically reduced.

Therefore, in order to realize that the display equipment automatically enters the disturbance-free mode, the background timing can be started when the controller receives an instruction once, and the statistical duration is accumulated. The instructions received by the controller include, but are not limited to, interactive instructions such as a secondary screen brightness adjustment instruction, a message display instruction, and the like, and the instructions may be generated by triggering of a user or instructions issued by a server to a display device.

In some embodiments, the preset time period for triggering the display device to automatically enter the do-not-disturb mode may be set to 1 minute or 2 minutes, that is, the controller does not receive any instruction within 1 minute or 2 minutes, that is, the controller automatically enters the do-not-disturb mode, and at this time, the controller executes a screen turning process.

In the no-disturbance mode, the second display is in a screen-off state, and therefore the brightness value of the second display is the no-disturbance screen-off value. In some embodiments, the value of the undisturbed rest screen brightness can be set to 5, or can be other values, and is not limited herein.

In some embodiments, if the counted duration exceeds the preset duration, it indicates that the controller does not receive the next instruction, and at this time, the brightness of the second display needs to be adjusted to the disturbance-free rest screen brightness value, so as to obtain the preset disturbance-free rest screen brightness value of the second display. Based on the disturbance-free information screen brightness value and the corresponding relation, the information screen background transparency of the window shielding layer can be determined.

And when entering the disturbance-free mode, acquiring the current brightness value of the current auxiliary screen, wherein the current brightness value can be converted according to the current background transparency and the corresponding relation of the window mask layer. If the current brightness value exceeds the disturbance-free rest screen brightness value, the brightness reduction process needs to be executed when the display device enters the disturbance-free mode, namely, the current background transparency of the window mask layer needs to be reduced to the rest screen background transparency corresponding to the disturbance-free rest screen brightness value.

FIG. 14 illustrates a graphical representation of the effect of sub-screen brightness entering a do-not-disturb mode, according to some embodiments. At this time, referring to fig. 14, the second display enters the rest mode and the display device enters the do-not-disturb mode. The background transparency value of the window mask layer is small (about 60), the shading degree of the window mask layer is deep, after the window mask layer covers the first user interface, the displayed content of the auxiliary screen is large in fuzzy degree and not easy to see by a user, and the visual effect that the auxiliary screen is dark is presented.

Therefore, according to the display device provided by the embodiment of the invention, when the disturbance-free automatic adjustment of the brightness of the auxiliary screen is executed, the interval time of the command received by the controller is counted in real time, and if the next command is not received when the counted time length after the command is received once exceeds the preset time length, the display device needs to enter the disturbance-free mode. At this time, if the current brightness value of the secondary screen exceeds the disturbance-free rest screen brightness value, the current background transparency of the window shielding layer is reduced to the rest screen background transparency corresponding to the disturbance-free rest screen brightness value, and the second display enters a rest screen mode. Therefore, when the auxiliary screen does not have any interaction and push, the brightness is automatically reduced after a period of time, namely the auxiliary screen and the display device are integrated into a whole in appearance, and the user cannot be disturbed when the user operates the large-screen content of the display device.

In some embodiments, to facilitate identification of the state of the second display, the identification may be based on different brightness of the second display to determine whether the display device is in a brightness adjustment mode or a no-disturb mode, the display state of the second display being a bright state or a dark state.

In some embodiments, in determining the mode of the display device and the state of the second display, the controller is further configured to perform the steps of:

and step 15, when the current brightness value of the second display exceeds the disturbance-free information screen brightness value, determining that the display equipment is in a brightness adjusting mode, and setting the display state of the second display to be a bright state.

And step 16, when the current brightness value of the second display does not exceed the disturbance-free rest screen brightness value, determining that the display device is in the disturbance-free mode, and setting the display state of the second display to be a dark state.

If the user self-defines the brightness of the auxiliary screen, the second display is not in the screen-off state, and in the scene, the current brightness value of the second display exceeds the disturbance-free screen-off brightness value, so that the display equipment can be determined to be in the brightness adjusting mode, and the display state of the second display is set to be the bright state.

If no interaction action exists between the user and the display device, the second display needs to enter a screen-off state, and in the scene, the current brightness value of the second display does not exceed the disturbance-free screen-off brightness value, so that the display device can be determined to be in the disturbance-free mode, and the display state of the second display is set to be a dark state.

In some embodiments, when the controller executes the do-not-disturb logic, if the current brightness value of the secondary screen is greater than the brightness value of the do-not-disturb rest screen and the screen status is bright, the secondary screen is required to be smoothly darkened to the brightness value of the do-not-disturb rest screen, and the screen status is set to be dark; and if the current brightness value is less than the disturbance-free screen-rest brightness value, the current brightness value is unchanged.

In some embodiments, by determining the display state of the second display, it may be determined whether the display device is in the do-not-disturb mode, so as to determine an execution policy of the controller, for example, the step of entering the do-not-disturb mode may be executed only when the display device is not in the do-not-disturb mode; the step of exiting the do-not-disturb mode may be performed only if the display device was originally in the do-not-disturb mode. If the second display is in a bright state, determining that the display device is not in the do-not-disturb mode; if the second display is in a dark state, the display device is determined to be in a do-not-disturb mode.

The foregoing embodiments provide a display device that, after normal startup of the display device, exhibits a window mask layer on a second display that is set to a default background transparency. And when the user performs self-defined brightness adjustment on the second display, simulating brightness change of the second display by changing the background transparency of the window mask layer.

In yet other embodiments, the display device may also automatically enter the do-not-disturb mode when no interaction has occurred for a period of time. If the display equipment generates interactive information again or generates a secondary screen brightness adjusting instruction in the disturbance-free mode, the second display needs to remove the disturbance-free mode and adjust the secondary screen brightness to a default brightness value or a user-defined brightness value.

FIG. 15 illustrates a second flow chart of a secondary screen brightness adjustment method according to some embodiments. The display device provided by the embodiment of the invention is applied to the display device of a double-screen single system, and comprises: a first display configured to present a first user interface; a second display configured to present a second user interface; a controller connected to the first display and the second display, the controller being configured to perform the following steps when performing the sub-screen brightness adjustment method shown in fig. 15:

s21, responding to a start-up instruction triggered by a user, acquiring a default brightness value of the second display, and displaying a window mask layer on an upper layer of the second display based on the default background transparency corresponding to the default brightness value.

When the display device is started, a power-on starting instruction is generated, and the controller responds to the power-on starting instruction to display the window mask layer set as the default background transparency in the second display. The process may refer to step S11 and related content executed by the controller in the display device provided in the foregoing embodiments, which are not described herein again.

S22, responding to a rest screen adjusting instruction carrying the disturbance-free rest screen brightness value, adjusting the default background transparency of the window mask layer to a rest screen background transparency corresponding to the disturbance-free rest screen brightness value, so that brightness adjustment of the second display is achieved through the window mask layer, the second display enters a rest screen mode, the display device enters the disturbance-free mode, and the disturbance-free rest screen brightness value is a brightness value corresponding to the situation that the second display is controlled to execute a rest screen process.

After the display device is started, if the controller does not interact with the second display any more, the controller does not send a message display instruction to the second display any more to display the secondary screen message. At this time, the sub-screen is in an unused state, the brightness of the sub-screen can be reduced, and the sub-screen enters a screen-off state, namely the sub-screen is in a dark state. Under the scene, the display equipment automatically enters the disturbance-free mode, and the brightness of the auxiliary screen is automatically reduced.

In order to facilitate timely and automatic control of the second display to turn off the screen when the display device is not interacted, the controller counts the counting time length of receiving the instruction every time in real time, if the counting time length after receiving the instruction once exceeds the preset time length and the next instruction is not received, the fact that the display device needs to enter the disturbance-free mode can be determined, the second display turns off the screen, and at the moment, the display device enters the disturbance-free mode from the normal brightness adjusting mode.

In some embodiments, the controller, in executing the instructions for adjusting the mute-free mute screen, is further configured to:

and step 221, starting timing from the previous instruction for indicating the display equipment is received, and if the next instruction is not received when the counted time length exceeds the preset time length, acquiring the brightness value of the disturbance-free information screen.

And step 222, generating a screen-off adjusting instruction based on the disturbance-free screen-off brightness value.

And when the counting time length exceeds the preset time length, the next instruction is not received, if a message display instruction or an auxiliary screen brightness adjusting instruction is not received, at the moment, the brightness of the second display needs to be reduced to the disturbance-free information screen brightness value. Therefore, the controller obtains the disturbance-free mute screen brightness value corresponding to the mute screen state, and generates a mute screen adjusting instruction carrying the disturbance-free mute screen brightness value. And after the controller receives the screen-off adjusting instruction, the brightness value of the second display can be reduced to the disturbance-free screen-off brightness value so as to enter a disturbance-free mode.

In some embodiments, when the brightness value of the second display is at a non-default brightness value, in which case the display device enters the do-not-disturb mode, the controller is further configured to perform the steps of:

and step 23, when the disturbance-free mode needs to be entered, acquiring the current background transparency of the window mask layer displayed in the second display and the current display state of the second display.

And 24, when the current brightness value corresponding to the current background transparency exceeds the disturbance-free rest screen brightness value and the current display state is a bright state, reducing the current background transparency of the window mask layer to the rest screen background transparency corresponding to the disturbance-free rest screen brightness value so as to reduce the brightness value of the second display to the disturbance-free rest screen brightness value, and setting the display state of the second display to be a dark state.

When the brightness is adjusted, the display state of the second display is judged first to determine whether the display equipment is in the disturbance-free mode, and the step of entering the disturbance-free mode can be executed only when the display equipment is not in the disturbance-free mode. If the second display is in a bright state, determining that the display device is not in the do-not-disturb mode; if the second display is in a dark state, the display device is determined to be in a do-not-disturb mode.

In some embodiments, when the controller executes the do-not-disturb logic, if the current brightness value of the secondary screen is greater than the brightness value of the do-not-disturb rest screen and the screen status is bright, the secondary screen is required to be smoothly darkened to the brightness value of the do-not-disturb rest screen, and the screen status is set to be dark; and if the current brightness value is less than the disturbance-free screen-rest brightness value, the current brightness value is unchanged. The implementation process may refer to the contents of step 13 to step 16 provided in the foregoing embodiments, and will not be described herein again.

In some embodiments, the controller may use a smooth adjustment to avoid visually perceiving a sudden increase or decrease in brightness when adjusting the brightness of the secondary screen. When the variation of the brightness is large, the sudden change of the brightness can affect the vision of the user, and the user experience is not good.

Therefore, the controller is further configured to, in performing the reducing of the current background transparency of the window mask layer to the tweet background transparency corresponding to the no-disturbance tweet brightness value:

and 241, calculating the transparency difference value of the current background transparency of the window mask layer and the background transparency of the information screen.

And 242, calculating a transparency adjustment step length based on the transparency difference and the adjustment time length required by the brightness adjustment.

Step 243, based on the transparency adjustment step size, the current background transparency of the window mask layer is reduced to the information screen background transparency.

In order to smoothly reduce the brightness of the auxiliary screen to the screen-saving brightness value, the transparency difference between the current background transparency of the window mask layer and the screen-saving background transparency can be calculated. And determining the transparency adjusting time according to the preset adjusting time. The adjustment time period required for the brightness adjustment is a time period for the display apparatus to perform the brightness adjustment once.

For each increase in brightness value by one value, the corresponding background transparency increases by 12 values. Thus, the transparency adjustment step characterizes the length of time required to adjust the transparency of the background for every 12.

For example, if the current sub-screen brightness value is 10, the corresponding current background transparency is 120; and if the screen-turning brightness value is 5, the screen-turning background transparency is 60, and the calculated transparency difference is 60. If the preset adjustment time is 500ms, the transparency adjustment step size is (60/12)/500-1/100, that is, 12 transparencies are adjusted every 100 ms.

After the transparency adjustment step length is determined, the current background transparency of the window mask layer can be smoothly reduced to the information screen background transparency. For example, when the background transparency 120 is reduced to 60, the transparency adjustment step size is 12 transparencies adjusted every 100ms, and the background transparency is reduced after 5 times of adjustment, that is, the first 100ms background transparency is reduced from 120 to 108; the second 100ms background transparency is reduced from 108 to 96; the third 100ms background transparency is reduced from 96 to 84; the fourth 100ms background transparency is reduced from 84 to 72; the fifth 100ms background transparency is reduced from 72 to 60.

The background transparency of the window mask layer is reduced in a grading manner, 12 values are reduced each time until the background transparency of the auxiliary screen is restored, the brightness of the corresponding auxiliary screen is reduced in a grading manner, and 1 value is reduced each time until the brightness value of the auxiliary screen is not disturbed, so that the smooth dimming effect of the brightness of the auxiliary screen is realized.

In some embodiments, after the display device enters the do-not-disturb mode, if the user needs to use the second display again, the brightness of the second display needs to be increased to a normal state. At this time, the do not disturb mode of the display device needs to be released.

In some embodiments, when the do-not-disturb mode needs to be exited, the controller is further configured to perform the steps of:

and 25, when the disturbance-free mode is switched to enter the brightness adjusting mode, responding to a secondary screen brightness adjusting instruction carrying a target brightness value, and acquiring a disturbance-free rest screen brightness value and a current display state of the second display.

And 26, when the target brightness value exceeds the disturbance-free rest screen brightness value and the current display state is a dark state, increasing the rest screen background transparency of the window mask layer to the target background transparency corresponding to the target brightness value, so as to increase the brightness value of the second display from the disturbance-free rest screen brightness value to the target brightness value, and setting the display state of the second display to be a bright state.

When the user needs to view the contents of the second display, the display device needs to be exited from the do-not-disturb mode. At this time, the display device needs to be switched from the disturbance-free mode to the brightness adjustment mode, and the display device can represent that the display device is in a state of normally displaying the content when entering the brightness adjustment mode.

In order to realize the brightness increase of the second display, a user can realize the self-defined setting of the auxiliary screen brightness through the auxiliary screen brightness adjusting interface presented in the first display, and at the moment, the controller generates an auxiliary screen brightness adjusting instruction carrying a target brightness value.

When the brightness is adjusted, the display state of the second display is judged first to determine whether the display equipment is in the disturbance-free mode, and the step of exiting the disturbance-free mode can be executed only when the display equipment is originally in the disturbance-free mode. If the second display is in a bright state, determining that the display device is not in the do-not-disturb mode; if the second display is in a dark state, the display device is determined to be in a do-not-disturb mode.

Therefore, when the target brightness value exceeds the disturbance-free rest screen brightness value and the current display state is the dark state, it is indicated that the current display device is in the disturbance-free mode, at this time, in order to facilitate the user to use the second display, the rest screen background transparency of the window mask layer needs to be increased to the target background transparency corresponding to the target brightness value, so as to increase the brightness value of the second display from the disturbance-free rest screen brightness value to the target brightness value, and the display state of the second display is set to the bright state. The implementation process of this process can refer to the content of step S12 and related steps provided in the foregoing embodiments, and details are not described here.

In some embodiments, the controller may use a smooth adjustment to avoid visually perceiving a sudden increase or decrease in brightness when adjusting the brightness of the secondary screen. For this reason, the implementation process of smoothly increasing the sub-screen brightness may refer to the content of smoothly decreasing the sub-screen brightness provided in steps 241 to 243 provided in the foregoing embodiment, and details thereof are not repeated herein.

In some embodiments, when the display device executes the non-disturbance logic, a screen-lighting process is executed, at this time, if a user-defined target brightness value of the secondary screen is greater than a non-disturbance-rest screen brightness value, and the screen state is dark, the secondary screen needs to be smoothly lightened to the target brightness value, and the screen state is set to be bright; and if the auxiliary screen target brightness value is smaller than the disturbance-free screen-rest brightness value, the auxiliary screen target brightness value is unchanged.

In some embodiments, the instructions received by the controller include an auxiliary screen brightness adjusting instruction and a message displaying instruction, so that when the controller executes a screen lightening process, the instruction capable of controlling the brightness increase of the auxiliary screen can be the auxiliary screen brightness adjusting instruction and can also be the message displaying instruction.

When the command is the auxiliary screen brightness adjusting command, the method can be adopted, and the auxiliary screen brightness is increased based on the user-defined target brightness value of the large screen.

When the message display instruction is received, the controller receives the message display instruction, and at the moment, in order to enable the second display to display the message content corresponding to the instruction, the screen-lighting operation is required to be executed. At this time, the controller increases the sub-screen brightness to a default brightness value or to a brightness value before entering the do-not-disturb mode.

Therefore, when the display device provided by the embodiment of the invention automatically adjusts the brightness of the secondary screen in the do-not-disturb mode, if the next instruction is not received when the counted time length after receiving the instruction once exceeds the preset time length, the display device needs to enter the do-not-disturb mode. At this time, if the current brightness value of the secondary screen exceeds the disturbance-free rest screen brightness value, the current background transparency of the window shielding layer is reduced to the rest screen background transparency corresponding to the disturbance-free rest screen brightness value, and the second display enters a rest screen mode. Therefore, when the auxiliary screen does not have any interaction and push, the brightness is automatically reduced after a period of time, namely the auxiliary screen and the display device are integrated into a whole in appearance, and the user cannot be disturbed when the user operates the large-screen content of the display device.

The display device provided by the foregoing embodiment is applied to a display device of a dual-screen single system when executing the sub-screen brightness adjustment method, and both displays are controlled by a common controller, that is, the display of the contents of the first display and the second display is controlled, and the brightness value of the second display is adjusted.

In other embodiments, the display device may also be a dual-screen dual-system display device, i.e., the first controller controls the display of each content in the first display and sends a broadcast to the second controller to inform the second controller to control the second display to display the content and adjust the brightness value of the second display. In the dual-screen dual-system display device, a first controller is a main controller, a second controller is an auxiliary controller, a message needing to be displayed in a second display is generated in the first controller, the first controller sends the message to the second controller, and the second controller controls the second display to display.

In some embodiments, a display device provided in an embodiment of the present invention is applied to a dual-screen dual-system display device, and includes: a first display configured to present a first user interface; a second display configured to present a second user interface; a first controller connected with the first display, the first controller configured to: receiving a starting-up instruction triggered by a user and an auxiliary screen brightness adjusting instruction carrying a target brightness value, respectively sending the starting-up instruction and the auxiliary screen brightness adjusting instruction carrying the target brightness value to a second controller, and adjusting the brightness value of the second display by the second controller.
