In some embodiments, the two displays can be controlled by a general controller. In this case, one controller is configured in the display device to form a dual-screen single-system display device. The controller communicates with the first display and the second display respectively, so as to realize the content display of the two displays.

In some embodiments, the two displays can be controlled by corresponding controllers respectively. In this case, two controllers are configured in the display device, which are the first controller and the second controller respectively, forming a dual-screen dual-system display. equipment. The first controller is configured with a first hardware system, which is a main chip; the second controller is configured with a second hardware system, which is a secondary chip.

The first controller is connected to the first display, and the second controller is connected to 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 the user operates the display device to generate a message or the device itself generates a message, the first controller sends the message that needs to be displayed on the second display to the second controller, so that the second controller displays the message on the second display middle.

When using dual screens of a display device to display content, it is usually possible to directly adjust the brightness of the main screen. However, due to the limitation of system hardware, the brightness of the secondary screen cannot be adjusted, which affects the user experience.

Therefore, in order to realize the brightness adjustment of the secondary screen of the display device, an embodiment of the present invention provides a display device, which adjusts the brightness of the secondary screen (the second display) through the UI on the main screen (the first display), so as to realize the cross-screen brightness adjustment; In order to visually check the brightness change, a UI interface is added to the secondary screen to simulate the brightness change. At the same time, according to the usage scenario, the brightness of the secondary screen can also be automatically adjusted, so as not to disturb the user to watch the content on the large screen, thereby ensuring that the secondary screen can realize the function of brightness adjustment and automatic adjustment.

In a dual-screen display device, a small screen is added below or above the large screen of the display device. For the brightness adjustment of the secondary screen, it is necessary to support the user-defined brightness of the secondary screen, and also need to consider how to automatically control the brightness. For this reason, based on this idea, this application has two functions for the brightness of the secondary screen: to support users to independently adjust the brightness of the secondary screen through the setting menu; when there is no interaction or push on the secondary screen, the brightness will be automatically adjusted after a period of time. Low, that is, it is integrated with the base of the display device in appearance, and will not disturb the user when the user operates the content on the large screen of the display device.

Fig. 7(a) shows an overall logical schematic diagram of the brightness adjustment of the existing secondary screen according to some embodiments; Fig. 7(b) shows another overall schematic diagram of the brightness adjustment of the existing secondary screen according to some embodiments Schematic diagram. Referring to FIG. 7( a ), when the user-defined secondary screen brightness is implemented, for a dual-system display device, the first controller configured in the display device communicates with the second controller through the RPC communication protocol, and the first controller is configured in The setting module and the Flow interface, the setting module is a system service (systemService) implemented by the brightness adjustment function, and the Flow interface can obtain the brightness value of the secondary screen defined based on the first display. At this time, the setting module in the first controller calls the Flow interface to obtain the brightness value of the secondary screen set by the user, and sends it to the second controller through the RPC communication protocol, and the conversion service configured in the second controller is based on the brightness value of the secondary screen. Adjust the brightness of the second monitor to change the screen brightness of the secondary monitor.

Referring to Figure 7(b), when implementing the do-not-disturb mode, the setting module in the first controller notifies the second controller based on the RPC communication protocol, and the second controller notifies the secondary screen Home (home page), and the Home timer ends via RPC Notify the setting module, and then the setting module calls the flow interface through RPC to set the conversion service configured in the second controller, so as to call the do-not-disturb interface, so as to automatically reduce the brightness of the secondary screen when the homepage of the secondary screen is not interacted for a period of time, and enter the information screen state.

Because not all models of display devices can adjust the brightness of the secondary screen, that is, some models of display devices call the screen brightness interface of the secondary screen does not work. Therefore, in order to realize that the brightness of the secondary screen can be adjusted for all types of display devices, the display device provided by the embodiment of the present invention simulates and adjusts the brightness of the secondary screen according to the following scheme.

When realizing the brightness adjustment of the secondary screen, the display device provided by this application retains the default settings of screen brightness (brightness adjustment mode) and do-not-disturb logic (do-not-disturb mode). "Conversion service" is changed to "Secondary screen brightness service". The secondary screen brightness service is used to adjust the brightness of the secondary screen.

Fig. 8(a) shows an overall logical schematic diagram of the brightness adjustment of the secondary screen of the present application according to some embodiments; Fig. 8(b) shows another overall schematic diagram of the brightness adjustment of the secondary screen of the present application according to some embodiments Schematic diagram. Referring to Figure 8(a), for a dual-system display device, when customizing the brightness of the secondary screen, the second controller calls the Flow interface in the first controller and simultaneously calls the secondary screen brightness service interface, that is, in the first controller The setting mode of the second controller directly performs RPC communication with the secondary screen brightness service in the second controller, and the secondary screen brightness service adjusts the secondary screen brightness through the obtained custom brightness value. Referring to Fig. 8(b), when the DND mode is implemented 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, and the second controller notifies the secondary screen Home (home page), Home When the timing is over, the setting module is notified through RPC, and then the setting module calls the flow interface through RPC to set the secondary screen brightness service configured in the second controller, so that the secondary screen enters the do-not-disturb mode.

For single-system display devices, when customizing the brightness of the secondary screen, the general controller configures and can directly call the secondary screen brightness service interface to start the secondary screen brightness service. The secondary screen brightness service obtains the custom brightness value through the Adjust the brightness of the secondary screen. When the DND mode is implemented to adjust the brightness of the secondary screen, the setting module in the controller notifies the secondary screen Home (home page), and the Home timer is over to notify the setting module through RPC, and then the setting module calls the secondary screen brightness service through RPC to realize the secondary screen entry. Do not disturb mode.

The startup of the secondary screen brightness service configured in the main controller in the single system or the second controller in the dual system is started by the device module (systemService): after the display device is turned on, the systemService is started, and then the secondary screen brightness service is triggered by the systemService. start. In order to enable the secondary screen to present a visual effect of light and dark changes when adjusting the brightness, the secondary screen brightness service starts a window mask (the highest level) in the second display, and the background transparency of the mask is divided from 0 to 170. 15 equal parts, indirectly simulate the brightness change by adjusting the background transparency.

The window mask is a window mask layer, which has the highest priority display order, that is, after startup, it will be displayed on the upper layer of the second user interface, that is, it will be covered on the second user interface. The window mask layer is in a transparent form, and the second user interface is blocked to different degrees by setting its background transparency, so as to simulate the change of the brightness of the secondary screen.

The internal logic of brightness adjustment implemented by the secondary screen brightness service is to call the secondary screen brightness value of the Flow layer through the RPC communication protocol, convert the secondary screen brightness value into the target background transparency, and then adjust the background of the window mask layer based on the target background transparency. Transparency to adjust the brightness of the secondary screen.

FIG. 9 shows a first flow chart of the method for adjusting the brightness of the secondary screen according to some embodiments; FIG. 10 shows a data flow diagram of the method for adjusting the brightness of the secondary screen according to some embodiments. In order to realize the brightness adjustment logic of the secondary screen provided above, an embodiment of the present invention provides a display device, which is applied to a display device of a dual-screen single-system, including: a first display configured to present a first user interface; a second display, is configured to present a second user interface; when the controller connected with the first display and the second display executes the method for adjusting the brightness of the secondary screen shown in FIG. 9 and FIG. 10 , the controller is configured to perform the following steps:

S11. Acquire a default brightness value of the second display in response to a user-triggered start-up instruction, and display a window mask layer on an upper layer of the second display based on a default background transparency corresponding to the default brightness value.

When starting the display device, the user triggers the power button of the display device to perform the power-on action. The power button may be the power button configured on the remote control of the display device or the power button configured on the display device itself. The user triggers the power button to generate a boot start command, the controller of the display device performs the boot action, and simultaneously starts the secondary screen brightness service configured in the controller, and presents the window mask layer on the second display through the secondary screen brightness service.

After the display device is started, the controller receives the start-up instruction, and acquires the default brightness value of the second display while displaying the second user interface on 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. Therefore, in order to realize the correspondence between the brightness value and the background transparency, the background transparency can be divided into 15 equal parts from 0 to 170. Each time the brightness value increases by one value, the background transparency increases by about 12 values. For example, when the secondary screen brightness value is 0, the background transparency is 0; when the secondary screen brightness value is 1, the background transparency is 12; when the secondary screen brightness value is 2 , the background transparency is 24; and so on, when the secondary screen brightness value is 15, the background transparency is 170. Therefore, when the user customizes the brightness value of the secondary screen in the first display, the user can indirectly simulate the brightness change in the second display by adjusting the background transparency.

Based on this, when powering on, the second controller invokes the secondary screen brightness service to obtain the default brightness value of the second display, and determines the default background transparency corresponding to the default brightness value according to the correspondence between the brightness value and the background transparency. Finally, the secondary screen brightness service generates a window mask layer according to the default background transparency, and displays 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 the default brightness value. Correspondingly, the window mask layer displayed by the second display has the default background transparency and is in a normal use state. Therefore, the brightness of the secondary screen is normal.

In some embodiments, the higher the background transparency value of the window mask layer is, the more transparent the visual effect is, and the brighter the brightness of the secondary screen is. Therefore, in the default background transparency, the value is higher, and the window mask layer is more transparent. At this time, the window mask layer is covered on the second user interface, so that the content displayed in the second user interface can be displayed through the display and can be displayed by the user. It can be clearly seen that the visual effect of the secondary screen is brighter.

In some embodiments, the smaller the background transparency value of the window mask layer is, the deeper the grayscale effect is in terms of visual effect, indicating that the brightness of the secondary screen is darker. If the user reduces the brightness value of the secondary screen, the corresponding background transparency value is smaller, and the window mask layer is darker. At this time, the window mask layer is covered on the second user interface, which will not make the content displayed in the second user interface. Through the display, the content will not be seen by the user or the user cannot see the content clearly, and the content displayed on the secondary screen is in a blurred state or a screen-off state, presenting a darker visual effect on the secondary screen.

S12, in response to the secondary screen brightness adjustment instruction that carries the target brightness value and is triggered and sent by the user, adjust the default background transparency of the window mask layer to the target background transparency corresponding to the target brightness value, so as to realize the second display through the window mask layer. Dimming.

After the display device is started, if the user needs to adjust the brightness of the second display, the target brightness value can be generated through the secondary screen brightness adjustment interface presented in the first display, and the secondary screen brightness adjustment command is generated at the same time, and the controller receives the secondary screen brightness. After the adjustment instruction, call the secondary screen brightness service to adjust the background transparency of the window mask layer, so as to realize the secondary screen brightness adjustment.

In some embodiments, when the user performs self-defined adjustment of the brightness of the secondary screen, the controller is further configured to perform the following steps when receiving the secondary screen brightness adjustment instruction triggered by the user and carrying the target brightness value:

Step 1211: Receive an operation on the system setting control in the first user interface, and display a secondary screen brightness adjustment interface including a brightness adjustment bar on the first display.

Step 1212: Receive an operation on the brightness adjustment bar, generate a target brightness value, and generate a secondary screen brightness adjustment instruction based on the target brightness value.

When the user needs to customize and adjust the brightness of the secondary screen, the user activates the system setting control through the remote control or voice. The system setting controls are displayed on the first user interface, and the user triggers the system setting controls to generate a secondary screen brightness adjustment interface, which is displayed on the first display.

FIG. 11 shows 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 brightness adjustment interface of the secondary screen, and the user can drag the brightness progress bar to move to the desired brightness value, that is, the target brightness value is generated. The brightness value can be displayed 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, such as the default background transparency corresponding to the default secondary screen brightness value of 12, and the secondary screen brightness effect diagram is shown in Figure 11. If the user needs to increase the brightness of the secondary screen, he can trigger the right key of the remote control direction key to trigger the brightness progress bar to move to the right to obtain the target brightness value, such as 13, 14, etc. If the user needs to reduce the brightness of the secondary screen, they can trigger the left arrow key on the remote control to trigger the brightness progress bar to move to the left to obtain the target brightness value, such as 11, 10, etc. Each time the arrow keys are triggered, the brightness value of a secondary screen is adjusted.

When the target brightness value required by the user is obtained, the sub-screen brightness adjustment instruction can be generated based on the target brightness value. The first controller sends the secondary screen brightness adjustment instruction to the second controller, and adjusts the background transparency of the window mask layer by calling the secondary screen brightness service, so as to realize the secondary screen brightness adjustment.

In some embodiments, when the user needs to customize the adjustment of the brightness of the secondary screen, the user can generate a target brightness value through the brightness adjustment interface of the secondary screen presented in the first display, and the controller receives the brightness of the secondary screen that carries the target brightness value. After the adjustment command, you can call the secondary screen brightness service to obtain the currently set secondary 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, and then adjust the original background transparency of the window mask layer. to the target background transparency, and adjust the background transparency accordingly so that the brightness of the secondary screen is the same as that of the main screen. The adjustment process of the window mask layer is the brightness adjustment process of the second display.

In some embodiments, the controller is further configured to: adjust the default background transparency of the window mask layer to the target background transparency corresponding to the target brightness value.

Step 1221: If the target brightness value exceeds the default brightness value, increase 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.

Step 1222: If the target brightness value does not exceed the default brightness value, reduce the default background transparency of the window mask layer to the target background transparency corresponding to the target brightness value to reduce the brightness value of the second display.

When the user needs to customize and adjust the brightness of the secondary screen, the user can lower the brightness of the secondary screen or increase the brightness of the secondary screen based on the actual situation, and then can simulate the secondary screen by reducing the background transparency of the window mask layer or increasing the background transparency of the window mask layer. Brightness changes.

When increasing the brightness of the secondary screen, the user can set the brightness value based on the brightness adjustment interface of the secondary screen shown in FIG. 11 presented on the first display to obtain the target brightness value. If the target brightness value is higher than the default brightness value (or the original brightness value), it means that the user wants to increase the brightness of the secondary screen. At this time, according to the corresponding relationship between the brightness value and the background transparency, the target background transparency is determined based on the target brightness value. The target background transparency is higher than the default background transparency (or original brightness value) of the window mask layer. Therefore, the second controller calls the secondary 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 the original brightness value) to the target brightness value, so as to realize the increase of the brightness of the secondary screen.

FIG. 12 shows a schematic diagram of the effect of increasing the brightness value of the secondary screen according to some embodiments. In some embodiments, referring to FIG. 12 , when the brightness value of the secondary screen is the default brightness value of 12 and the default background transparency of the window mask layer is about 144, if the user increases the brightness to the target brightness value through the brightness progress bar in the first display 14, then determine that the target background transparency is about 168. If the target brightness value is higher than the default brightness value, the background transparency of the window mask layer needs to be increased from the default background transparency of 144 to the target background transparency of 168. At this time, the brightness of the secondary screen is increased. The transparency of the background increases, the more transparent the window mask layer, the brighter the brightness of the secondary screen. After the window mask layer is covered on the second user interface, the content displayed in the second user interface is more clearly seen by the user. From the visual effect Look, the clearer the content that the user can see, the brighter the secondary screen.

When reducing the brightness of the secondary screen, the user can set the brightness value based on the brightness adjustment interface of the secondary screen shown in FIG. 11 presented on the first display to obtain the target brightness value. If the target brightness value is lower than the default brightness value (or the original brightness value), it means that the user wants to reduce the brightness of the secondary screen. At this time, according to the corresponding relationship between the brightness value and the background transparency, the target background transparency is determined based on the target brightness value. The target background transparency is lower than the default background transparency (or original brightness value) of the window mask layer. Therefore, the second controller calls the secondary 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 the original brightness value) to the target brightness value, so as to reduce the brightness of the secondary screen.

FIG. 13 shows a schematic diagram of the effect of reducing the brightness value of the secondary screen according to some embodiments. In some embodiments, referring to FIG. 13 , when the brightness value of the secondary screen is the default brightness value of 12 and the default background transparency of the window mask layer is about 144, if the user reduces the brightness to the target brightness value through the brightness progress bar in the first display 10, the target background transparency is determined to be about 120. If the target brightness value is lower than the default brightness value, the background transparency of the window mask layer needs to be reduced from the default background transparency of 144 to the target background transparency of 120. At this time, the brightness of the secondary screen is weakened. The transparency of the background decreases. The darker the grayscale of the window mask layer, the darker the brightness of the secondary screen. After the window mask layer is covered on the second user interface, the content displayed in the second user interface is not easy for users to see. In terms of effect, the more blurred the content that the user can see, the darker the secondary screen.

In some embodiments, when the user adjusts the brightness of the secondary screen through the secondary screen brightness adjustment interface displayed on the main screen, only the brightness of the secondary screen will change correspondingly with the user-defined brightness, while the brightness of the main screen will not be adjusted according to the user's custom brightness. Brightness change, that is, when the content is displayed on the large screen, the user adjusts the brightness of the secondary screen, which will not affect the content of the main screen and avoid affecting the normal use of the user. Among them, the brightness of the main screen can be adjusted according to its own logic for adjusting the brightness of the main screen.

It can be seen that, in the display device provided by the embodiment of the present invention, when the user-defined brightness of the secondary screen is executed, the user realizes the custom setting of the brightness value of the secondary screen based on the brightness adjustment interface of the secondary screen displayed in the first display, and the controller responds to carrying the target brightness. The secondary screen brightness adjustment command of the value, call the secondary screen brightness service to obtain the user-defined target brightness value from the flow interface, determine the target background transparency of the window mask layer according to the target brightness value, and then change the original background transparency of the window mask layer. Adjust to the target background transparency, and adjust the background transparency accordingly so that the brightness of the secondary screen is consistent with the settings of the main screen, so as to adjust the brightness of the secondary screen.

In some embodiments, the display device provided by the present application can not only adjust the brightness of the secondary screen independently by the user through the secondary screen brightness adjustment interface, but also automatically reduce the brightness after a period of time when there is no interaction or push on the secondary screen. , that is, it is integrated with the base of the display device in appearance, and will not disturb the user when the user operates the content on the large screen of the display device.

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

Step 13. Start timing from the receipt of the previous command triggered by the user. If the next command is not received when the statistical duration exceeds the preset duration, obtain the current brightness value of the second display and the brightness value of the do-not-disturb screen. Do not disturb The screen-on-screen brightness value refers to a corresponding brightness value when the second display performs the screen-off process.

Step 14. If the current brightness value exceeds the brightness value of the DND screen, the current background transparency of the window mask layer is reduced to the screen background transparency corresponding to the DND screen brightness value, and the second display enters the screen mode, displaying the device. Enter Do Not Disturb mode, 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 to display prompt messages. Therefore, the controller will respond to the message display instruction from time to time to display the corresponding message content on the second display. At this time, the second display The brightness needs to remain at the normal default brightness state, or at a brightness value where the content can be clearly seen by the user.

If the controller no longer interacts with the second display, for example, no longer sends a message display instruction to the second display to display the message on the secondary screen. At this time, the secondary screen is in an unused state, and the brightness of the secondary screen can be lowered to enter the off-screen state, that is, the secondary screen is in a dark state. In this scenario, the display device automatically enters the Do Not Disturb mode, and the brightness of the secondary screen is automatically reduced.

Therefore, in order to realize that the display device automatically enters the do-not-disturb mode, the background timing can be started when the controller receives an instruction, and the statistical time period can be accumulated. The instructions received by the controller include, but are not limited to, interactive instructions such as secondary screen brightness adjustment instructions and message display instructions.

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

In the do-not-disturb mode, the second display is in an on-screen state. Therefore, the brightness value of the second display is the value of the do-not-disturb off-screen degree. In some embodiments, the DND screen brightness value may be set to 5, or may be other values, which are not limited here.

In some embodiments, if the statistical duration exceeds the preset duration, it means that the controller has not received the next instruction. At this time, the brightness of the second display needs to be adjusted to the brightness value of the DND screen, and then the preset first display is obtained. The brightness value of the DND screen on the second monitor. Based on the brightness value of the DND screen and the corresponding relationship, the screen background transparency of the window mask layer can be determined.

When entering the do-not-disturb mode, the current brightness value of the current secondary screen is obtained, and the current brightness value can be converted according to the current background transparency of the window mask layer and the corresponding relationship. If the current brightness value exceeds the DND screen brightness value, it means that when the display device enters the DND mode, the brightness reduction process needs to be performed, that is, the current background transparency of the window mask layer needs to be reduced to the value corresponding to the DND screen brightness value. Screen background transparency.

FIG. 14 is a schematic diagram illustrating the effect of the brightness of the secondary screen when entering the do not disturb mode according to some embodiments. At this time, referring to FIG. 14 , the second display enters the keep-screen mode, and the display device enters the do-not-disturb mode. The background transparency value of the window mask layer is small (about 60), and the window mask layer is darker. After the window mask layer is covered on the first user interface, the content displayed on the secondary screen is more blurred, and it is not easy to be displayed by the user. You can see that the visual effect of the secondary screen is darker.

It can be seen that in the display device provided by the embodiment of the present invention, when the DND automatically adjusts the brightness of the secondary screen, the real-time statistics of the interval time of the controller receiving the command, if the statistical time after receiving an command exceeds the preset time, no data is received The next command, 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 brightness value of the DND screen, the current background transparency of the window mask layer is reduced to the background transparency of the screen corresponding to the brightness value of the DND screen, and the second display enters the screen mode. . Therefore, when there is no interaction or push on the secondary screen, the brightness is automatically lowered after a period of time, that is, it is integrated with the base of the display device in appearance, and will not disturb the user when the user operates the content on the large screen of the display device.

In some embodiments, in order to facilitate the identification of the state of the second display, identification may be performed according to different brightness of the second display to determine whether the display device is in a brightness adjustment mode or a do not disturb mode, and the display state of the second display is: light state or 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 following steps:

Step 15: When the current brightness value of the second display exceeds the brightness value of the do-not-disturb screen, determine that the display device is in the brightness adjustment mode, and set the display state of the second display to the bright state.

Step 16: When the current brightness value of the second display does not exceed the brightness value of the do-not-disturb screen, determine that the display device is in the do-not-disturb mode, and set the display state of the second display to a dark state.

If the user customizes the brightness of the secondary screen, the second display is not in the screen-off state. In this scenario, if the current brightness value of the second display exceeds the brightness value of the DND screen, it can be determined that the display device is in the brightness adjustment mode, and set The display state of the second display is a bright state.

If there is no interaction between the user and the display device, the second display needs to enter the non-disturbing state. In this scenario, if the current brightness value of the second display does not exceed the brightness value of the non-disturbing non-disturbing screen, it can be determined that the display device is in the non-disturbing mode. , and set the display state of the second display to a dark state.

In some embodiments, when the controller executes the DND logic, if the current brightness value of the secondary screen is greater than the DND screen brightness value, and the screen status is bright, the secondary screen needs to be smoothly dimmed to the DND screen brightness value , and, set the screen status to dark; if the current brightness value is less than the DND screen brightness value, it will not change.

In some embodiments, by judging the display state of the second display, it can be determined whether the display device is in the do-not-disturb mode, so as to determine the execution strategy of the controller, for example, only when the display device is not in the do-not-disturb mode can execute the entry The steps for DND mode; the steps to exit DND mode can only be performed if the display device was originally in DND mode. If the second display is in the bright state, it is determined that the display device is not in the do not disturb mode; if the second display is in the dark state, it is determined that the display device is in the do not disturb mode.

In the display device provided by the foregoing embodiment, after the display device is normally started, the second display displays the window mask layer set as the default background transparency. When the user adjusts the custom brightness of the second display, the brightness change of the second display is simulated by changing the background transparency of the window mask layer.

In other embodiments, the display device may also automatically enter the do-not-disturb mode when there is no interaction for a period of time. If in the DND mode, the display device generates interactive information again or generates an instruction to adjust the brightness of the secondary screen, the second display needs to cancel the DND mode and adjust the brightness of the secondary screen to the default brightness value or a user-defined brightness value.

FIG. 15 shows a second flowchart of a method for adjusting the brightness of a secondary screen according to some embodiments. A display device provided by an embodiment of the present invention is applied to a display device of a dual-screen single-system. The device includes: a first display configured to present a first user interface; a second display configured to present a second user interface ; The controller connected with the first display and the second display, when executing the method for adjusting the brightness of the secondary screen shown in Figure 15, the controller is configured to perform the following steps:

S21. Acquire a default brightness value of the second display in response to a user-triggered start-up instruction, and display a window mask layer on the upper layer of the second display based on the default background transparency corresponding to the default brightness value.

When the display device is activated, a power-on activation command is generated, and the controller responds to the power-on activation command to display the window mask layer set as the default background transparency in the second display. For this process, reference may be made to the execution step S11 of the controller in the display device provided in the foregoing embodiments and related contents, which will not be repeated here.

S22. In response to the screen-on-screen adjustment instruction carrying the brightness value of the screen-free screen, the default background transparency of the window mask layer is adjusted to the background transparency of the screen-on-screen corresponding to the brightness value of the screen-free screen, so as to realize the second screen through the mask layer of the window. The brightness of the display is adjusted, the second display enters the screen-off mode, and the display device enters the do-not-disturb mode. The do-not-disturb screen-on-screen brightness value refers to the corresponding brightness value when the second display is controlled to perform the screen-off process.

After the display device is started, if the controller no longer interacts with the second display, for example, it no longer sends a message display instruction to the second display to display messages on the secondary screen. At this time, the secondary screen is in an unused state, and the brightness of the secondary screen can be lowered to enter the off-screen state, that is, the secondary screen is in a dark state. In this scenario, the display device automatically enters the Do Not Disturb mode, and the brightness of the secondary screen is automatically reduced.

In order to automatically control the screen of the second display when the display device is not interacting, the controller counts the statistical duration of each received command in real time. If the statistical duration after receiving an command exceeds the preset duration, the next With one command, it can be determined that the display device needs to enter the do-not-disturb mode, and the screen of the second display is off. At this time, the display device enters the do-not-disturb mode from the normal brightness adjustment mode.

In some embodiments, the controller is further configured to:

Step 221: Start timing from receiving the previous instruction indicating the display device. If the next instruction is not received when the counted duration exceeds the preset duration, obtain the brightness value of the DND screen.

Step 222 , based on the brightness value of the DND screen, generate a screen adjustment instruction.

When the statistical time exceeds the preset time, the next command is not received. If the message display command or the secondary screen brightness adjustment command is not received, at this time, the brightness of the second display needs to be reduced to the DND screen brightness value. Therefore, the controller obtains the brightness value of the DND screen corresponding to the status of the screen, and generates a screen adjustment instruction carrying the brightness value of the DND screen. After the controller receives the adjustment instruction of the screen, it can reduce the brightness value of the second display to the brightness value of the non-disturb screen, so as to enter the non-disturb 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 following steps:

Step 23: When it is necessary to enter the do-not-disturb mode, obtain the current background transparency of the window mask layer displayed in the second display and the current display state of the second display.

Step 24: When the current brightness value corresponding to the current background transparency exceeds the brightness value of the DND screen, and when the current display state is the bright state, reduce the current background transparency of the window mask layer to the value corresponding to the DND screen brightness value. the transparency of the screen background, so as to reduce the brightness value of the second display to the brightness value of the non-disturbing screen, and set the display state of the second display to be a dark state.

When adjusting the brightness, the display state of the second display is first judged to determine whether the display device is in the do-not-disturb mode, and the step of entering the do-not-disturb mode can be performed only when the display device is not in the do-not-disturb mode originally. If the second display is in the bright state, it is determined that the display device is not in the do-not-disturb mode; if the second display is in the dark state, it is determined that the display device is in the do-not-disturb mode.

In some embodiments, when the controller executes the DND logic, if the current brightness value of the secondary screen is greater than the DND screen brightness value, and the screen status is bright, the secondary screen needs to be smoothly dimmed to the DND screen brightness value , and, set the screen status to dark; if the current brightness value is less than the DND screen brightness value, it will not change. For the implementation process, reference may be made to the contents of step 13 to step 16 provided in the foregoing embodiment, which will not be repeated here.

In some embodiments, when the controller adjusts the brightness of the secondary screen, a smooth adjustment method may be adopted to prevent the user from visually feeling a sudden increase or decrease of the brightness. When the change of brightness is large, the sudden change of brightness will affect the user's vision, and the user experience is not good.

Therefore, the controller is further configured to:

Step 241: Calculate the transparency difference between the current background transparency of the window mask layer and the background transparency of the screen.

Step 242: Calculate the transparency adjustment step size based on the difference in transparency and the adjustment duration required for brightness adjustment.

Step 243 , based on the transparency adjustment step, reduce the current background transparency of the window mask layer to the screen background transparency.

In order to smoothly reduce the brightness of the secondary screen to the brightness value of the full screen, the transparency difference between the current background transparency of the window mask layer and the background transparency of the screen can be calculated. Then, according to the preset adjustment duration, determine the transparency adjustment duration. The adjustment duration required for brightness adjustment is the duration for the display device to perform one brightness adjustment.

Since the brightness value increases by one value, the corresponding background transparency increases by 12 values. Therefore, the transparency adjustment step represents the time required to adjust the transparency of every 12 backgrounds.

For example, if the brightness value of the current secondary screen is 10, the corresponding current background transparency is 120; the brightness value of the active screen is 5, the background transparency of the active screen is 60, and the calculated transparency difference is 60. If the preset adjustment duration is 500ms, the transparency adjustment step is (60/12)/500=1/100, that is, 12 transparencys are adjusted every 100ms.

After the transparency adjustment step is determined, the current background transparency of the window mask layer can be smoothly reduced to the screen background transparency. For example, when the background transparency is reduced from 120 to 60, and the transparency adjustment step is 12 per 100ms, the background transparency needs to be adjusted 5 times to reduce the background transparency, that is, the background transparency is reduced from 120 to 108 in the first 100ms; 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 decreased in stages, by 12 values each time until the background transparency of the hidden screen, and the brightness of the corresponding secondary screen is decreased in stages, by 1 value each time to the brightness value of the non-disturbing screen, so as to realize the secondary screen. Smooth dimming effect of brightness.

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. In this case, the Do Not Disturb mode of the display device needs to be released.

In some embodiments, when it is necessary to exit the do not disturb mode, the controller is further configured to perform the following steps:

Step 25: When switching from the DND mode to the brightness adjustment mode, in response to the secondary screen brightness adjustment instruction carrying the target brightness value, obtain the DND screen brightness value and the current display state of the second display.

Step 26: When the target brightness value exceeds the DND screen brightness value, and when the current display state is a dark state, increase the screen-on-screen background transparency of the window mask layer to the target background transparency corresponding to the target brightness value, so as to increase the second The brightness value of the display is increased from the brightness value of the DND screen to the target brightness value, and the display state of the second display is set to a bright state.

When the user needs to view the content of the second display, the display device needs to exit the do-not-disturb mode. At this time, the display device needs to be switched from the do-not-disturb mode to the brightness adjustment mode, and the display device enters the brightness adjustment mode to indicate that the display device is in a state of displaying content normally.

To increase the brightness of the second display, the user can customize the brightness of the secondary screen through the secondary screen brightness adjustment interface displayed on the first display. At this time, the controller generates a secondary screen brightness adjustment instruction carrying the target brightness value.

When adjusting the brightness, the display state of the second display is first judged to determine whether the display device is in the DND mode, and the step of exiting the DND mode can be performed only when the display device is originally in the DND mode. If the second display is in the bright state, it is determined that the display device is not in the do-not-disturb mode; if the second display is in the dark state, it is determined that the display device is in the do-not-disturb mode.

For this reason, when the target brightness value exceeds the DND screen brightness value, and the current display state is dark, it means that the current display device is in the DND mode. At this time, in order to facilitate the user to use the second display, the window needs to be covered. The transparency of the screen background of the layer is 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 brightness value of the non-disturbing screen to the target brightness value, and set the display state of the second display to the bright state . For the implementation process of this process, reference may be made to the content of step S12 and related steps provided in the foregoing embodiments, which will not be repeated here.

In some embodiments, when the controller adjusts the brightness of the secondary screen, a smooth adjustment method may be adopted to prevent the user from visually feeling a sudden increase or decrease of the brightness. Therefore, for the implementation process of smoothly increasing the brightness of the secondary screen, reference may be made to the content of smoothly reducing the brightness of the secondary screen proposed in steps 241 to 243 provided in the foregoing embodiments, which will not be repeated here.

In some embodiments, when the display device executes the logic to exit DND, it needs to perform a screen brightening process. At this time, if the user-defined target brightness value of the secondary screen is greater than the DND screen brightness value, and the screen state is dark, Then the secondary screen needs to be smoothly brightened to the target brightness value, and the screen status should be set to bright; if the target brightness value of the secondary screen is less than the brightness value of the DND screen, it will not change.

In some embodiments, the instructions received by the controller include a secondary screen brightness adjustment instruction and a message display instruction, so that when the controller performs a screen brightening process, the instruction that can control the brightness of the secondary screen to increase may be a secondary screen brightness adjustment instruction, or Displays instructions for messages.

When it is an instruction to adjust the brightness of the secondary screen, the aforementioned method can be used to increase the brightness of the secondary screen based on the target brightness value customized by the user on the large screen.

When displaying the instruction for the message, the controller receives the message displaying instruction, and at this time, in order for the second display to display the message content corresponding to the instruction, a screen-on operation needs to be performed. At this time, the controller increases the brightness of the secondary screen to the default brightness value or to the brightness value before entering the DND mode.

It can be seen that when the display device provided by the embodiment of the present invention automatically adjusts the brightness of the secondary screen in the do-not-disturb mode, if the statistical time period after receiving an instruction exceeds the preset time period and does not receive the next instruction, 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 brightness value of the DND screen, the current background transparency of the window mask layer is reduced to the background transparency of the screen corresponding to the brightness value of the DND screen, and the second display enters the screen mode. . Therefore, when there is no interaction or push on the secondary screen, the brightness is automatically lowered after a period of time, that is, it is integrated with the base of the display device in appearance, and will not disturb the user when the user operates the content on the large screen of the display device.

When the display device provided in the foregoing embodiment executes the method for adjusting the brightness of the secondary screen, it is applied to a display device of a dual-screen single-system, and both displays are controlled by a general controller, that is, the control of the first display and the second display. The content is displayed, 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, that is, 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 The second display is controlled to display the content, and the brightness value of the second display is adjusted.
