[0001] The present application relates to the technical field of display devices, in particular to a display device and a volume bar display method. BACKGROUND

[0002] With the rapid development of display devices, users have more ways to control display devices. For example, a user can not only play a television program by selecting a channel through a remote controller, but also play a television program by manipulating a touch screen with a finger.

[0003] In the process of playing a television program, the user usually adjusts the volume. The user can adjust the volume through a remote controller, a hardware button on the display device, or by manipulating a touch screen with a finger. In some scenarios, the user may adjust the volume through at least two volume adjustment methods, such as adjusting the volume through a touch screen, adjusting the volume through a remote controller, and adjusting the volume through a hardware button, which causes a volume adjustment conflict.

[0004] In the above scenario, the display device is usually configured to only respond to a touch adjustment instruction sent by the user through the touch screen, and not to respond to a key adjustment instruction sent by the user through the remote controller or a hardware adjustment instruction sent by the user through the hardware button. In addition, the volume bar control cannot simultaneously display the volume bar adjusted by at least two adjustment methods, which affects the user experience. SUMMARY

[0054] In some embodiments, the controller 250 controls the operation of the display device and responds to the user's operation by storing various software control programs in the memory. The controller 250 controls the overall operation of the display device 200. For example, in response to receiving a user command for selecting a UI object displayed on the display 260, the controller 250 can perform an operation related to the object selected by the user command.

[0064] Figure 4 For the software configuration diagram in the display device 200 according to one or more embodiments of the present application, as shown in Figure 4 The system is divided into four layers from top to bottom, namely the application layer (referred to as "application layer"), the application framework layer (referred to as "framework layer"), the Android runtime and system library layer (referred to as "system runtime library layer"), and the kernel layer. The kernel layer at least includes at least one of the following drivers: audio driver, display driver, Bluetooth driver, camera driver, WIFI driver, USB driver, HDMI driver, sensor driver (such as fingerprint sensor, temperature sensor, pressure sensor, etc.), and power supply driver, etc.

[0065] Figure 5 For the icon control interface display diagram of the application program in the display device 200 according to one or more embodiments of the present application, as shown in Figure 5 The application layer includes at least one application program that can display corresponding icon controls in the display, such as: live TV application icon control, video on demand application icon control, media center application icon control, application center icon control, game application icon control, etc. The live TV application program can provide live TV through different signal sources. The video on demand application program can provide videos from different storage sources. Unlike the live TV application program, the video on demand provides video display from certain storage sources. The media center application program can provide various multimedia content playing application programs. The application center can provide storage of various application programs.

[0066] When the user uses an application program capable of playing audio, the user has a demand for various volume information display and adjustment, and the display device 200 is usually configured as Figure 6The volume bar control is shown. A user can control the display device 200 through the control device 100 or the terminal device 300 to adjust various volume information in the volume bar control.

[0067] For the display device 200 with touch function, taking a touch TV as an example, the touch TV is a TV that replaces a conventional display screen with a touch screen with touch function on the basis of a common TV, so that the common TV has touch function. The touch screen of the touch TV is an inductive liquid crystal display device that can accept touch pen, finger and other input signals. A user can control the display device 200 through a touch pen, finger to adjust the volume bar control.

[0068] Figure 7 An example of a display device usage scenario is shown. As shown in Figure 7 In the scenario where multiple people watch the display device 200 with touch function at the same time, the first user adjusts the volume bar control by clicking the touch screen with a finger, and at the same time, the second user adjusts the volume bar control through the control device 100 or the terminal device 300. At this time, the display device 200 receives the touch adjustment instruction sent by the first user and the key adjustment instruction sent by the second user. In the current scenario, the display device 200 is usually configured to only respond to the touch adjustment instruction, that is, after the display device 200 receives the touch adjustment instruction sent by the first user, it no longer responds to the key adjustment instruction sent by the second user through the control device 100 or the terminal device 300.

[0069] Figure 8 Another example of a display device usage scenario is shown. As shown in Figure 8 In the scenario where multiple people watch the display device 200 with touch function at the same time, the first user adjusts the volume bar control by clicking the touch screen with a finger, and at the same time, the third user adjusts the volume bar control through the hardware button on the display device 200. At this time, the display device 200 receives the touch adjustment instruction sent by the first user and the hardware adjustment instruction sent by the third user. In the current scenario, the display device 200 is usually configured to only respond to the touch adjustment instruction, that is, after the display device 200 receives the touch adjustment instruction sent by the first user, it no longer responds to the hardware adjustment instruction sent by the third user through the hardware button.

[0070] The usage scenarios of the display device 200 also include the case where the first user, the second user and the third user send touch adjustment instructions, key adjustment instructions and hardware adjustment instructions at the same time. In this scenario, the display device 200 only responds to the touch adjustment instruction and does not respond to the key adjustment instruction and the hardware adjustment instruction.

[0071] In the above use scenarios, the display device 200 only responds to the touch adjustment instruction. In the state of responding to the touch adjustment instruction, the display device 200 no longer responds to other adjustment instructions. Meanwhile, the volume bar control displayed by the display device 200 only displays the volume bar corresponding to the touch adjustment instruction, and cannot simultaneously display the volume bar corresponding to other adjustment instructions.

[0072] Figure 9 An exemplary user mis-touch scenario is shown in the figure. As shown in the figure, when the touch adjustment instruction sent by the first user is a mis-touch adjustment instruction (for example, the finger of the first user mis-touches and causes a long press on a certain position of the volume bar control of the touch screen), because the display device 200 only responds to the touch adjustment instruction of the first user and does not respond to the key adjustment instruction of the second user, the second user cannot adjust the volume bar control through the control device 100 or the terminal device 300, resulting in that the current volume played by the display device 200 according to the touch adjustment instruction does not meet the actual needs of the user. Figure 9

[0073] Because the finger of the first user mis-touches and causes the volume bar control to be in a touch state, the volume bar control continuously sends a callback message of the volume at the touch position of the finger. At this time, even if the second user adjusts the volume through the control device 100 or the terminal device 300, the volume will continuously recover to the volume at the touch position of the finger, resulting in that the adjustment of the second user on the volume has no effect. Therefore, the display device 200 cannot simultaneously respond to the touch adjustment instruction and the key adjustment instruction for adjustment, and the volume bar control of the display device 200 can also only respond to the touch adjustment instruction for display and cannot simultaneously respond to the touch adjustment instruction and the key adjustment instruction for display, resulting in that the second user cannot adjust the key adjustment instruction according to the value of the key adjustment instruction. The process of the conflict between the first user and the third user in adjusting the volume is the same.

[0074] In some scenarios, the display device 200 has a demand to simultaneously respond to at least two adjustment instructions and needs to play the volume according to the appropriate adjustment instruction. Correspondingly, on the basis that the display device 200 can simultaneously respond to at least two adjustment instructions, the display device 200 also needs to display the volume bar corresponding to the at least two adjustment instructions, so that the user can determine the appropriate volume bar to play the corresponding volume according to the displayed volume bar.

[0075] In order to solve the problem of the conflict between the volume adjustment modes and the conflict between the volume bar controls when the display device with a touch function adjusts the volume, some embodiments of the present application provide a display device which can accurately determine the volume adjustment mode and simultaneously display the volume bar corresponding to at least two adjustment instructions in the volume bar control.

[0076] ​In some embodiments of the present application, the display 260 can be configured to display a volume bar control, and the controller 250 is configured to store the at least one first adjustment instruction and the at least one second adjustment instruction in the message queue according to the order of receiving, as shown in the display device configuration flowchart. Figure 10 As shown in the display device configuration flowchart, the display device 200 receives at least one first adjustment instruction for adjusting the first volume sent by the first user, and receives at least one second adjustment instruction for adjusting the second volume sent by the second user, and then stores the at least one first adjustment instruction and the at least one second adjustment instruction in the message queue according to the order of receiving.

[0077] The first user can send at least one first adjustment instruction for adjusting the first volume to the display device 200 through the control device 100, and the display device 200 stores the at least one first adjustment instruction in the message queue according to the receiving time of the display device 200 in response to the first adjustment instruction.

[0078] In the process of data interaction, the user can control the display device 200 through the control device 100; the control device 100 can communicate in a direct wireless connection mode or in a non-straight connection mode. That is, in some embodiments, the control device 100 can communicate with the display device 200 in a direct connection mode such as Bluetooth or infrared. When the user sends a first adjustment instruction to the display device 200 through the control device 100, the control device 100 can directly send the first adjustment instruction to the display device 200 through Bluetooth or infrared.

[0079] In some embodiments, the control device 100 can also access the same wireless network with the display device 200 through a wireless router to establish a non-direct connection communication with the display device 200 through the wireless network. When the control device 100 sends a first adjustment instruction, the control device 100 can first send the first adjustment instruction to the wireless router, and then forward the first adjustment instruction to the display device 200 through the wireless router.

[0080] The first user can send at least one first adjustment instruction for adjusting the first volume to the display device 200 through the touch screen, and the display device 200 stores the at least one first adjustment instruction in the message queue according to the receiving time of the display device 200 in response to the first adjustment instruction.

[0081] The first user can send at least one first adjustment instruction for adjusting the first volume to the display device 200 through the hardware button of the display device 200, and the display device 200 stores the at least one first adjustment instruction in the message queue according to the receiving time of the display device 200 in response to the first adjustment instruction.

[0082] When the first user sends the first adjustment instruction, the second user can send the second adjustment instruction through a different sending end. For example, when the first user sends the first adjustment instruction through the touch screen, the second user can send the second adjustment instruction through the control device 100 or the hardware button; when the first user sends the first adjustment instruction through the control device 100, the second user can send the second adjustment instruction through the touch screen or the hardware button; when the first user sends the first adjustment instruction through the hardware button, the second user can send the second adjustment instruction through the touch screen or the control device 100. It should be noted that the second user sends the second adjustment instruction through a different sending end in the same way as the first user sends the first adjustment instruction, and the display device 200 stores the second adjustment instruction in the same way as storing the first adjustment instruction, which will not be described here.

[0083] Figure 11 An exemplary first adjustment instruction adjusts the first volume scene schematic diagram is shown. As shown in Figure 11 The display device 200 can obtain the first volume direction, the first volume change step, the first volume starting value, and the first volume ending value according to the first adjustment instruction. The first adjustment instruction is used to increase or decrease the first volume. For example, the current volume of the display device 200 can be 10. After receiving the first adjustment instruction, taking the first adjustment instruction as a touch adjustment instruction, the first volume is obtained by adjusting the current volume through the touch adjustment instruction. The first volume can increase the current volume from 10 to 12, or decrease the current volume from 10 to 8.

[0084] The display device 200 displays the first volume bar corresponding to the first adjustment instruction when receiving the first adjustment instruction sent by the first user. The first volume direction can be used to adjust the increase or decrease direction of the first volume. For example, when the first adjustment instruction is used to increase the first volume, the first volume bar moves to the right and the length increases. At this time, the first volume direction is used to adjust the increase direction of the first volume, that is, the right direction. Correspondingly, when the first adjustment instruction is used to decrease the first volume, the first volume bar moves to the left and the length decreases. At this time, the first volume direction is used to adjust the decrease direction of the first volume, that is, the left direction. The first volume starting value can be set to 10, corresponding to 30 decibels. The first volume change step is used to adjust the change value of the first volume. For example, the first volume change step can be set to 2. When the first adjustment instruction is used to increase the first volume, the first volume bar moves to the right by a first volume change step. At this time, the value of the first volume changes from 10 to 12. The first volume ending value is 12.

[0085] The display device 200 can acquire a second volume direction, a second volume change step, a second volume start value and a second volume end value according to a second adjustment instruction. The second adjustment instruction is used to increase or decrease the second volume. The display device 200 displays the second volume bar corresponding to the second adjustment instruction when receiving the second adjustment instruction sent by the user. The second volume adjustment direction is used to adjust the increasing or decreasing direction of the second volume, and the second volume change step is used to adjust the change value of the second volume. The adjustment manner of the second volume bar is the same as that of the first volume bar, and is not described herein.

[0086] In the process of adjusting the volume by the user, in order to ensure that the user can adjust the volume to a suitable value, the user usually needs to send multiple adjustment instructions. Taking that the first user sends a first adjustment instruction through the control device 100 as an example, the current volume of the display device 200 is 10, the first user clicks the "volume +" button on the control device once, which is considered that the first user sends a first adjustment instruction, at this time, the first volume direction is right, the first volume step is 2, the first volume start value is 10, and the first volume end value is 12. The first user clicks the "volume +" button on the control device again, which is considered that the first user sends the first adjustment instruction again, at this time, the first volume direction is right, the first volume step is 2, the first volume start value is 12, and the first volume end value is 14. If the first user needs to adjust the first volume to 20, at least 5 first adjustment instructions need to be sent continuously.

[0087] In the process of sending at least one first adjustment instruction by the first user, the second user can send a second adjustment instruction in the process. The display device 200 alternately responds to the first adjustment instruction and the second adjustment instruction, and stores the first adjustment instruction and the second adjustment instruction in the message queue according to the received order.

[0088] Figure 12 The message queue schematic diagram of some embodiments of the present application is exemplarily shown. As shown in the figure, Figure 12 The display device 200 responds to the first first adjustment instruction at 0:00:00, responds to the second first adjustment instruction at 0:00:02, responds to the first second adjustment instruction at 0:00:03, responds to the third first adjustment instruction at 0:00:04, and responds to the second second adjustment instruction at 0:00:05. After the display device 200 stores the first adjustment instruction and the second adjustment instruction in the message queue according to the received order, the display device 200 acquires the most recent first adjustment instruction and the most recent second adjustment instruction in the message queue. As shown in the figure, Figure 12The message queue shows that the display device 200 can obtain the third first adjustment instruction at 0:00:04 and the second second adjustment instruction at 0:00:05.

[0089] The first user sends the first adjustment instruction, and the second user sends the second adjustment instruction can be a process of uninterrupted sending, for example, the first user long-presses the touch screen to send the first adjustment instruction, and the second user long-presses the "volume +" button on the control device 100 to send the second adjustment instruction. The first user sends the first adjustment instruction, and the second user sends the second adjustment instruction can also be a process of multiple intermittent sending, for example, the first user multiple taps the touch screen to send the first adjustment instruction, and the second user multiple taps the "volume +" button on the control device 100 to send the second adjustment instruction.

[0090] It should be noted that when the first adjustment instruction or the second adjustment instruction is a sending mode of uninterrupted sending, the display device 200 responds to the first adjustment instruction or the second adjustment instruction intermittently. For example, the first user sends the first adjustment instruction uninterruptedly in the time period of 0:00:00-0:00:06, and the display device 200 splits the first adjustment instruction sent continuously in this time period into multiple first adjustment instructions by default for storage, that is, the display device 200 stores the first first adjustment instruction at 0:00:00, the second first adjustment instruction at 0:00:02, the third first adjustment instruction at 0:00:04, and the fourth first adjustment instruction at 0:00:06.

[0091] Therefore, the adjustment instructions sent in various sending modes such as the first adjustment instruction of uninterrupted sending, the second adjustment instruction of uninterrupted sending, the first adjustment instruction of multiple intermittent sending, and the second adjustment instruction of multiple intermittent sending can be stored in order in the message queue, and the display device 200 can play the first volume or the second volume according to the storage order in the message queue, and simultaneously display the first volume bar corresponding to the first adjustment instruction and the second volume bar corresponding to the second adjustment instruction.

[0092] Figure 13 An exemplary schematic diagram of the volume bar control adjustment mode in some embodiments of the present application is shown. As shown in FIG. 2, the display device 200 can display the first volume bar corresponding to the first adjustment instruction and the second volume bar corresponding to the second adjustment instruction simultaneously. Figure 13As shown, the first adjustment instruction is only used to adjust the corresponding first volume bar, the second adjustment instruction is only used to adjust the corresponding second volume bar, and there is no case that the first adjustment instruction and the second adjustment instruction adjust the same volume bar at the same time. For example, the current volume of the display device 200 is 10, the display device 200 adjusts the first volume to 12 in response to a first first adjustment instruction at 0:00:00, and the first volume bar moves two steps to the right. The display device 200 adjusts the first volume to 14 in response to a second first adjustment instruction at 0:00:02, and the first volume bar moves two steps to the right again. The display device 200 adjusts the second volume to 12 in response to a first second adjustment instruction at 0:00:03, and the display device 200 adjusts the first volume to 16 in response to a third first adjustment instruction at 0:00:04. At this time, the first volume bar displays that the first volume is 16, and the second volume bar displays that the second volume is 12.

[0093] After the display device 200 stores the first adjustment instruction and the second adjustment instruction in the message queue, the display device 200 obtains that the end of the message queue is the first adjustment instruction or the second adjustment instruction. If the end of the message queue is the first adjustment instruction, the display device 200 adjusts the first volume according to the first adjustment instruction, so that the display device 200 plays the first volume. If the end of the message queue is the second adjustment instruction, the display device 200 adjusts the second volume according to the second adjustment instruction, so that the display device 200 plays the second volume.

[0094] In some embodiments, when the display device 200 does not receive the first adjustment instruction, the display device 200 sets the current volume corresponding to the volume bar control to a default value. After the display device 200 receives the first adjustment instruction, the display device 200 compares the first volume corresponding to the first adjustment instruction with the default value. If the first volume is the same as the default value, the default value is not updated. If the first volume is different from the default value, the first volume is updated as the default value. For example, the current volume of the display device 200 is 10, and the display device 200 receives a touch adjustment instruction as the first adjustment instruction. The first user touches the position of the current volume 10 in the volume bar control with a finger, so that the first volume is the same as the default value, and the default value is not updated. The current default value is 10. If the first user touches the position of the current volume 16 in the volume bar control with the finger, the first volume is different from the default value, and the default value is updated as 16. In this embodiment, the same default value is not repeatedly set.

[0095] When the first user long-presses the touchscreen to send a first adjustment command, the first user touches the current volume setting of 10. At this time, the second user sends a second adjustment command, and the second user can adjust the second volume to 12 using the control device 100. Since the second volume is different from the default value, the display device 200 can update the default value to 12 and play the corresponding second volume. Using this embodiment, the display device 200 avoids the problem of repeatedly setting the same default value, which would cause the display device to only respond to touch adjustment commands and not button adjustment commands.

[0096] Since both the first user and the second user can see the first volume bar and the second volume bar simultaneously, they can determine the appropriate volume level using the first and second volume bars and play the volume accordingly.

[0097] Figure 14 An exemplary diagram illustrating a user adjusting volume is provided. Figure 14 As shown, the first user adjusts the current volume according to their usual volume value. For example, the first user usually adjusts the volume to 20. The first user adjusts the first volume to 16 via the touchscreen, while the second user adjusts the second volume to 12 via the control device 100. Since both users can see the first and second volume bars displayed on the volume control, the first volume can be adjusted to 20 more quickly, while the second volume takes longer to adjust to 20. Therefore, the first user can signal the second user to stop adjusting the second volume and only adjust the first volume, avoiding the situation where both users are unsure of their current volume level and adjust it together.

[0098] When the first user adjusts the volume based on the current scenario, taking a noisy environment as an example, the first user typically judges the appropriate volume by ear. For instance, in a noisy environment, the appropriate volume value for display device 200 is 25. The first user needs to repeatedly adjust the volume to determine the appropriate volume for the human ear. If the first user sends a first adjustment command at 0:00:00 to adjust the first volume to 28, and the second user sends a second adjustment command at 0:00:01 to adjust the second volume to 20, the message queue end is 20. Display device 200 then plays the second volume to 20. Since the appropriate volume is not reached, the first and second users adjust again. This time, the second user sends a second adjustment command at 0:00:06 to adjust the second volume to 24, and the first user sends a first adjustment command at 0:00:08 to adjust the second volume to 26. The message queue end is now 26, and display device 200 plays the first volume to 26. When both the first and second adjustment commands can be used to adjust and determine the playback volume, display device 200 can quickly determine the range of appropriate volume and adjust it to the appropriate volume.

[0099] Figure 15 An example is shown in FIG. 2A, which shows a schematic diagram of a volume bar control layer in some embodiments of the present application. As shown in FIG. 2A, the display device 200 is provided with a first layer, a second layer, a third layer and a background layer in the volume bar control, the drawing levels of the first layer to the third layer are sequentially decreased, wherein the first layer is used to display the volume bar corresponding to the touch adjustment instruction, the second layer is used to display the volume bar corresponding to the key adjustment instruction, the third layer is used as a standby display layer of the volume bar, and the background layer is located at the next layer of the second layer, and is located between the second layer and the third layer in a normal case. Figure 15

[0100] Since the drawing levels of the first layer to the third layer are sequentially decreased, the drawing content on the first layer can be covered on the second layer, and the drawing content on the second layer can be covered on the third layer.

[0101] In some embodiments, the display device 200 can create a congestion window (CWnd) control in the Microsoft Foundation Classes (MFC) as a container for drawing the volume bar control, and the display device 200 can set a callback function for message callback through the congestion window control to customize the drawing of the volume bar, wherein the callback function is defined by the function binding method provided by the BOOST library, then the external function is set to the callback function value defined in the internal by the method provided by the library, and finally the callback is called in the control, and the function implementation is defined externally.

[0102] In some embodiments, the display device 200 can set the volume bar control based on the Progressbar component.

[0103] The display device 200 can also define the specific properties of the volume bar control through the congestion function control, such as the volume value, the background color and the background transparency, and the display device 200 can realize the background rendering according to the background color or picture properties configured by the congestion control.

[0104] Figure 16 An example is shown in FIG. 2A, which shows a schematic diagram of a volume bar control layer in some embodiments of the present application. As shown in FIG. 2A, the display device 200 is provided with a first layer, a second layer, a third layer and a background layer in the volume bar control, the drawing levels of the first layer to the third layer are sequentially decreased, wherein the first layer is used to display the volume bar corresponding to the touch adjustment instruction, the second layer is used to display the volume bar corresponding to the key adjustment instruction, the third layer is used as a standby display layer of the volume bar, and the background layer is located at the next layer of the second layer, and is located between the second layer and the third layer in a normal case. Figure 16 ​As shown, when the display device 200 obtains the latest first adjustment instruction and the latest second adjustment instruction from the message queue, the display device 200 can obtain the first volume termination value corresponding to the first adjustment instruction from the latest first adjustment instruction, and the first volume termination value is 16 in the example. The display device 200 can also obtain the second volume termination value corresponding to the second adjustment instruction from the latest second adjustment instruction, and the second volume termination value is 12 in the example. Since the first volume termination value is 16 and the second volume termination value is 12, the length of the first volume bar is greater than the length of the second volume bar.

[0105] When the first adjustment instruction is a touch adjustment instruction, the first volume bar is drawn on the first layer, and when the second adjustment instruction is a key adjustment instruction, the second volume bar is drawn on the second layer. Since the length of the first volume bar is greater than the length of the second volume bar, and the drawing level of the first layer is higher than the drawing level of the second layer, the first volume bar covers the second volume bar.

[0106] When the second adjustment instruction is a touch adjustment instruction, the second volume bar is drawn on the first layer, and when the first adjustment is a key adjustment instruction, the first volume bar is drawn on the second layer. Since the length of the second volume bar is greater than the length of the first volume bar, and the drawing level of the first layer is higher than the drawing level of the second layer, the second volume bar covers the first volume bar.

[0107] It should be noted that the first adjustment instruction and the second adjustment instruction can be distinguished according to the order in which the display device 200 receives them. For example, the adjustment instruction received by the display device 200 at 0:00:00 can be the first adjustment instruction, and the adjustment instruction received by the display device 200 at 0:00:02 can be the second adjustment instruction.

[0108] Figure 17 An example of the layer changing manner of some embodiments of the present application is shown in the schematic diagram as shown in Figure 17 As shown, when the first adjustment instruction is a touch adjustment instruction and the first volume termination value is greater than the second volume termination value, the display device 200 sets the drawing level of the third layer to be higher than that of the first layer to control the third layer to display the second standby volume bar and the first layer to display the first volume bar; wherein the display manner of the second standby volume bar is the same as that of the second volume bar.

[0109] Since the first volume displayed by the first volume bar is 16 and the second volume displayed by the second volume bar is 12, although the first layer displays the first volume bar and the second layer displays the second volume bar, at this time the second volume bar is covered by the first volume bar, thus the second standby volume bar is displayed on the third layer, the second standby volume displayed by the second standby volume bar is 12, the length of the second standby volume bar is less than the length of the first volume bar and the length of the second standby volume bar is different from the length of the first standby volume bar, thus the second standby volume bar does not cover the first volume bar, the display device 200 can make the volume bar control simultaneously display the second standby volume bar and the first volume bar by distinguishing the color and the length, so that the user can determine the appropriate volume.

[0110] In some embodiments, when the second adjusting instruction is the touch adjusting instruction and the second volume end value is greater than the first volume end value, the display device 200 sets the drawing level of the third layer to be higher than the first layer, so as to control the third layer to display the first standby volume bar and the first layer to display the second volume bar; wherein the display method of the first standby volume bar is the same as that of the first volume bar.

[0111] When the second adjusting instruction is the touch adjusting instruction, the second volume bar is drawn on the first layer, at this time the first adjusting instruction is the key adjusting instruction, the first volume bar is drawn on the second layer, when the length of the second volume bar is greater than the length of the first volume bar, since the drawing level of the first layer is higher than that of the second layer, thus the second volume bar covers the first volume bar. The specific embodiments of displaying the first standby volume bar when the second adjusting instruction is the touch adjusting instruction and the second volume bar covers the first volume bar are the same as those of displaying the second standby volume bar in the above embodiments, which will not be described herein.

[0112] Figure 18 Exemplary display mode of the volume bar control of some embodiments of the present application is shown in the schematic diagram. As shown in the figure, Figure 18 When the first adjusting instruction is the touch adjusting instruction and the first volume end value is less than the second volume end value, the display device 200 controls the first layer to display the first volume bar and controls the second layer to display the second volume bar; at this time the length of the first volume bar is less than that of the second volume bar, the first volume bar cannot completely cover the second volume bar, the first user and the second user can simultaneously watch the first volume bar and the second volume bar.

[0113] When the second adjusting instruction is the touch adjusting instruction and the second volume end value is less than the first volume end value; the display device 200 controls the first layer to display the second volume bar and controls the second layer to display the first volume bar; at this time the length of the second volume bar is less than that of the first volume bar, the second volume bar cannot completely cover the first volume bar, the first user and the second user can simultaneously watch the second volume bar and the first volume bar.

[0114] It should be noted that when the display device 200 simultaneously receives the first adjustment instruction and the second adjustment instruction, the first layer to the third layer of the display device 200 are all in the open state.

[0115] When the first user sends the touch adjustment instruction alone, the volume bar control only opens the first layer and the background layer, and the second layer and the third layer are in the closed state. When the second user sends the key adjustment instruction alone, the volume bar control only opens the second layer and the background layer, and the first layer and the third layer are in the closed state. The volume bar control in some embodiments of the present application can display the corresponding volume bar in the case of receiving only the touch adjustment instruction, receiving only the key adjustment instruction, and simultaneously receiving the touch adjustment instruction and the key adjustment instruction, which can improve the user experience.

[0116] From the above technical solutions, it can be seen that the display device provided by the above embodiments can store the first adjustment instruction and the second adjustment instruction in the same message queue, determine the most recent first adjustment instruction and the most recent second adjustment instruction in the message queue, and display the first volume bar and the second volume bar, respectively, so that the user can determine the appropriate volume bar and determine the playback volume through the appropriate volume bar. The technical solution shown in the present application can solve the problem of conflict between touch volume adjustment and key volume adjustment when the display device with touch function adjusts the volume, and the problem of volume bar control display conflict. It can accurately determine the volume adjustment mode and simultaneously display the volume bar corresponding to the touch volume adjustment and the volume bar corresponding to the key volume adjustment in the volume bar control.

[0117] It should be noted that the volume bar control layer shown in the above embodiments is only set for the scenario where the touch adjustment instruction and the key adjustment instruction are sent simultaneously. In order to be applicable to more application scenarios, some embodiments of the present application also show a technical solution that can support displaying the volume bar corresponding to at least two adjustment instructions.

[0118] In some embodiments of the present application, the display 260 can be configured to display a volume bar control, and the controller 250 is configured to display the volume bar control according to the display device configuration flowchart as shown in FIG. 6. Figure 19 In some embodiments of the present application, the display 260 can be configured to display a volume bar control, and the controller 250 is configured to display the volume bar control according to the display device configuration flowchart as shown in FIG. 6.

[0119] The first adjustment command, the second adjustment command, and the third adjustment command are determined according to the order in which they are received by the display device 200.

[0120] The display device 200 retrieves the most recent first adjustment instruction, the most recent second adjustment instruction, and the most recent third adjustment instruction from the message queue, determines a first volume in response to the most recent first adjustment instruction, determines a second volume in response to the most recent second adjustment instruction, and determines a third volume in response to the third adjustment instruction.

[0121] The display device 200 controls the volume bar to display the first volume bar corresponding to the first volume, the second volume bar corresponding to the second volume, and the third volume bar corresponding to the third volume.

[0122] In some embodiments, after the display device 200 stores the first adjustment instruction, the second adjustment instruction, and the third adjustment instruction in a message queue, the display device 200 obtains that the end of the message queue is the first adjustment instruction, the second adjustment instruction, or the third adjustment instruction. If the end of the message queue is the first adjustment instruction, the display device 200 adjusts the first volume according to the first adjustment instruction to make the display device 200 play the first volume; if the end of the message queue is the second adjustment instruction, the display device 200 adjusts the second volume according to the second adjustment instruction to make the display device 200 play the second volume; if the end of the message queue is the third adjustment instruction, the display device 200 adjusts the third volume according to the third adjustment instruction to make the display device 200 play the third volume.

[0123] Figure 20 Exemplary illustrations are shown of volume bar control layers in some embodiments of this application. For example... Figure 20 As shown, the display device 200 has a first layer, a second layer, a third layer, a fourth layer, a fifth layer, and a background layer in the volume bar control. The first layer has a higher drawing level than the second layer, the second layer has a higher drawing level than the fourth layer, the fourth layer has a higher drawing level than the background layer, the background layer has a higher drawing level than the third layer, and the third layer has a higher drawing level than the fifth layer. The first layer displays the volume bar corresponding to touch adjustment commands, the second layer displays the volume bar corresponding to button adjustment commands, the fourth layer displays the volume bar corresponding to hardware adjustment commands, the third layer serves as the first backup display layer for the volume bar, and the fifth layer serves as the second backup display layer for the volume bar.

[0124] Figure 21 The illustration shows a schematic diagram illustrating the display method of the volume bar control in some embodiments of this application. For example... Figure 21As shown, when the display device 200 obtains the last first adjusting instruction, the last second adjusting instruction and the last third adjusting instruction from the message queue, the display device 200 can obtain the first volume termination value corresponding to the first adjusting instruction from the last first adjusting instruction, the second volume termination value corresponding to the second adjusting instruction from the last second adjusting instruction and the third volume termination value corresponding to the third adjusting instruction from the last third adjusting instruction. The display device 200 displays the volume bar corresponding to different adjusting instructions in different layers of the volume bar control.

[0125] In some embodiments, when the first adjusting instruction is the touch adjusting instruction, the second adjusting instruction is the key adjusting instruction and the third adjusting instruction is the hardware adjusting instruction, the display device 200 displays the touch adjusting instruction in the first layer, displays the key adjusting instruction in the second layer and displays the hardware adjusting instruction in the fourth layer. Since the lengths of the first volume bar, the second volume bar and the third volume bar are different and the drawing level of the first layer is higher than that of the second layer and the fourth layer, when the first volume bar is the volume bar corresponding to the touch adjusting instruction and the first volume termination value is greater than the second volume termination value and the third volume termination value, the first volume bar covers the second volume bar and the third volume bar.

[0126] Figure 22 An exemplary schematic diagram of the layer changing manner of some embodiments of the present application is shown. As shown in the figure, Figure 22 When the first volume bar displayed in the first layer is 20, the second volume bar displayed in the second layer is 18 and the third volume bar displayed in the fourth layer is 16, the drawing level of the third layer is set to be higher than that of the first layer to control the third layer to display the second backup volume bar, and the drawing level of the fifth layer is set to be higher than that of the third layer to control the fifth layer to display the third backup volume bar. The display manner of the second backup volume bar is the same as that of the second volume bar, and the display manner of the third backup volume bar is the same as that of the third volume bar. The display device 200 can display the first volume bar, the second backup volume bar and the third backup volume bar in the volume bar control by distinguishing the colors and lengths, so that the user can determine the appropriate volume.

[0127] It should be noted that when the display device 200 simultaneously receives the first adjusting instruction, the second adjusting instruction and the third adjusting instruction, the first layer, the second layer, the third layer, the fourth layer, the fifth layer and the background layer in the volume bar control are simultaneously started to adapt to the value changes corresponding to different adjusting instructions.

[0128] When the display device 200 simultaneously receives the first adjustment instruction and the second adjustment instruction, only the first layer, the second layer, the third layer and the background layer in the volume bar control are turned on; when the display device 200 simultaneously receives the first adjustment instruction and the third adjustment instruction, only the first layer, the fourth layer, the fifth layer and the background layer in the volume bar control are turned on; the volume bar control with 6 layers shown in this embodiment can be applied to more scenarios than the volume bar control with 4 layers shown in the foregoing embodiments, and has better compatibility.

[0129] Figure 23 An interface prompt schematic diagram in some embodiments of the present application is exemplarily shown. As shown in Figure 23 During the process that the volume bar control simultaneously displays multiple volume bars, the display device 200 displays an interface prompt, which can be: “Multiple users are currently adjusting the volume. Please select a way to adjust.” By using this embodiment, the prompt function can be played in the scenario of multiple people simultaneously adjusting the volume, which facilitates the user to quickly determine the appropriate volume.

[0130] From the technical solutions shown above, it can be known that the display device provided by the above embodiments can determine the most recent first adjustment instruction, the most recent second adjustment instruction and the most recent third adjustment instruction in the message queue by storing the first adjustment instruction, the second adjustment instruction and the third adjustment instruction in the same message queue, to display the first volume bar, the second volume bar and the third volume bar respectively, so that the user can determine the appropriate volume bar and determine the playback volume through the appropriate volume bar. The technical solutions shown in the present application can solve the problems of conflict between at least two volume adjustment methods such as touch adjustment, key adjustment and hardware adjustment when the display device with touch function adjusts the volume, and display conflict of the volume bar control, can accurately determine the volume adjustment method, and simultaneously display the volume bar corresponding to the touch adjustment and the volume bar corresponding to the key adjustment in the volume bar control.

[0131] Based on the display device 200 shown in the above embodiments, the application further provides a volume bar display method, including: obtaining at least one first adjustment instruction, the first adjustment instruction being a touch adjustment instruction sent by a touch screen or a key adjustment instruction sent by a control device; the first adjustment instruction being used to adjust a first volume; in the process of analyzing the at least one first adjustment instruction, obtaining at least one second adjustment instruction, the second adjustment instruction being different from the first adjustment instruction in sending end; the second adjustment instruction being used to adjust a second volume; sorting the at least one first adjustment instruction and the at least one second adjustment instruction in a message queue; obtaining a last first adjustment instruction and a last second adjustment instruction in the message queue; and synchronously displaying a first volume bar corresponding to the last first adjustment instruction and a second volume bar corresponding to the last second adjustment instruction.

[0132] In some embodiments, in the step of sorting the at least one first adjustment instruction and the at least one second adjustment instruction in the message queue, if the last end of the message queue is the first adjustment instruction, the first volume is adjusted according to the first adjustment instruction to play the first volume; if the last end of the message queue is the second adjustment instruction, the second volume is adjusted according to the second adjustment instruction to play the second volume.

[0133] From the above technical solutions, the volume bar display method provided by the above embodiments can determine the last first adjustment instruction and the last second adjustment instruction in the message queue by sorting the first adjustment instruction and the second adjustment instruction in the same message queue, to display the first volume bar and the second volume bar respectively, so that the user can determine the appropriate volume bar and determine the playing volume through the appropriate volume bar. The technical solutions shown in the application can solve the problems of conflict between touch volume adjustment and key volume adjustment and conflict of volume bar control display when the display device with touch function adjusts the volume, can accurately determine the volume adjustment mode, and simultaneously display the volume bar corresponding to the touch volume adjustment and the volume bar corresponding to the key volume adjustment in the volume bar control.
