The driving mainly comprises: audio drive, display drive, bluetooth drive, camera drive, WIFI drive, USB drive, HDMI drive, sensor drive (e.g., fingerprint sensor, temperature sensor, pressure sensor, etc.), and power supply drive, etc.

The above embodiments introduce the content of the hardware/software architecture, the functional implementation, etc. of the display device. In an exemplary implementation, at least one function key may be provided locally to the display device, and the number of keys and key types may be set according to actual basic function requirements. Further, the individual keys are not limited in location, ordering, distribution, etc. on the display device housing.

In an exemplary implementation, optionally, the display device native keys include a Power key, a Menu key, a Source key, a channel_up key, a channel_down key, a volume_up key, and a volume_down key, and initial preset functions of these keys are: the Power key is a Power key and is used for controlling the starting and the shutting of the display equipment; the Menu key is a Menu key and is used for displaying a Menu page when triggered; the Source key is used for switching the signal Source of the display device; the Channel up key and the Channel down key are Channel adjusting keys for adjusting Channel programs forward and backward respectively; the volume_up key and the volume_down key are Volume adjusting keys, the volume_up key is used for increasing the Volume value of a built-in speaker or an external power amplifier of the display device, and the volume_down key is used for reducing the Volume value of the built-in speaker or the external power amplifier of the display device.

In some application scenarios, the remote controller equipped with the display device may be damaged, lost or unavailable due to battery no power, so that a user cannot control the display device through the remote controller, and functions of local keys of the display device are preset, and are single, for example, menu keys are used for displaying a Menu when triggered, source keys are used for switching signal sources when triggered, that is, only an initial preset function can be executed, while the number of local keys of the display device is limited and less than that of the remote controller, so that certain functions cannot be triggered and executed through the local keys of the display device, for example, by moving a focus up, down, left and right, confirming options, exiting pages, and other high-frequency function operations still have to depend on the remote controller.

In this regard, the present application provides a scheme for multiplexing functions of the native keys of the display device, so that when a user performs a specific operation on a key on a designated interface, the initial preset function of the key is not executed any more, but the multiplexing function of the customized configuration of the key is executed.

In an exemplary implementation, some interfaces require that the native keys must perform an initial preset function, such as a Channel up or down key on a cable television viewing interface, a Channel switch function by clicking the Channel up or down key, and a Volume adjustment function by clicking the Volume up or down key, because these keys are associated with the television play base function, and if other multiplexing functions of these keys are performed on the video play interface, it will be necessary to affect the normal viewing of the video by the user. For example, when the user clicks the channel_up key, the channel_down key, the volume_down key and the volume_up key, the user can control the focus to move along the up, down, left and right directions respectively, so as to adjust the focus position, and after the focus is determined, the user clicks the Source key again, namely, the confirmation operation is input, so that the preset multiplexing function is added to the local key of the display device, and the function operation triggered by the key is adapted to the requirements of different interface display scenes.

In an exemplary implementation, a preset interface type supporting the key multiplexing function may be set, i.e., the key multiplexing function is enabled when the display device displays the preset interface type, without having to perform an initial preset function of the key, such as a menu page, a system home page, an application home page, etc.

In an exemplary implementation manner, the display device may maintain a first preset list, where the first preset list includes preset interface types supporting the key multiplexing function, and a user may perform operations such as adding, deleting, and emptying the preset interface types on the first preset list according to actual application requirements. Since the first preset list needs to be updated according to the user setting, the first preset list may be an empty list or a non-empty list (i.e. at least including one preset interface type).

In an exemplary implementation, when the first preset list is an empty list, indicating that the interface type supporting the key multiplexing function is not specified currently, then no matter what UI interface is displayed by the display, only executing the initial preset function when the key is triggered; if the first preset list is a non-empty list, the interface type currently displayed by the display is required to be compared with the first preset list, if the first preset list comprises the current interface type, a multiplexing function corresponding to a key preset by a user is executed, and the initial preset function of the key is not executed any more; if the first preset list does not comprise the current interface type, executing the initial preset function of the key, and not starting the multiplexing function corresponding to the key.

In an exemplary implementation, a "key Setting" option may be added to a Setting (Setting) page of the display device to support a user to customize configuration of a multiplexing function of each local key in the "key Setting" page, and to set a triggering manner of the key multiplexing function when a preset interface type is displayed. For example, when a preset interface type is displayed, a long press of the Menu key triggers a Home function of a return system homepage, a single press of the Menu key triggers a return to a previous function (corresponding to a return key on the remote controller), a single press of the Source key triggers a confirm function (corresponding to a confirm/OK key on the remote controller), a single press of the channel_up key triggers a direction up function (corresponding to an up key on the remote controller), a single press of the channel_down key triggers a direction down function (corresponding to a down key on the remote controller), a single press of the volume_down key triggers a direction left function (corresponding to a left key on the remote controller), a single press of the volume_up key triggers a direction right function (corresponding to a right key on the remote controller), and so on. The user can refer to daily use habit, and the high-frequency key function of the remote controller is synchronously adapted to the key multiplexing function of the display equipment end, so that when the remote controller is unavailable, the user can execute required functional operation by triggering the television local key, and the user experience is improved.

In one exemplary implementation, a user may choose to set at least one preset multiplexing function for each individual key, each preset multiplexing function being associated with a triggering operation of that key, thereby forming a multiplexed function set for each key. For example, for the Menu key, the user returns to the previous stage/step when clicking the Menu key, returns to the system homepage when clicking the Menu key for a long time, and displays the application center when clicking the Menu key, i.e. the multiplexing function set of the Menu key comprises 3 preset multiplexing functions. If a certain key is not provided with any preset multiplexing function, the multiplexing function set of the key is an empty set, and the default initial preset function is executed when the key is triggered. Because the multiplexing function setting of each local key can be adjusted by a user at any time according to personal wish in the long-term use process of the television, the multiplexing function set of each key is not fixed.

In an exemplary implementation, assuming that the total number of keys set on the display device housing is N, the user performs customization of multiplexing functions for M keys therein, where M is less than or equal to N, i.e., where the multiplexing function set of M keys is not null, and the multiplexing function set of N-M keys is null. When M is equal to N, the user presets the multiplexing function for all the local keys. If M is smaller than N, when the display device displays the preset interface type, the M keys enable the preset multiplexing functions matched with each other if triggered, and in addition, the N-M keys still execute the corresponding initial preset functions if triggered; if M is smaller than N, and the display device displays a non-preset interface type, the N local keys still execute the corresponding initial preset functions when triggered. That is, the user may select to set multiplexing functions for all the local keys, or may set multiplexing functions for only some of the local keys, and the key not set with multiplexing functions still keeps executing its initial preset function when triggered, without being affected by the type of interface currently displayed by the display device, for example, the Power key is a key not having multiplexing functions, and execute the Power function when the display device is in a Power-off state (no UI interface display) and clicks the Power key; when the display device is in a starting-up running state, the type of an interface currently displayed by the display device is not required to be considered, and as long as clicking operation on a Power key is received, a shutdown function is executed.

In an exemplary implementation manner, when the first preset list is a non-empty list, the display device currently displays a preset interface type in the first preset list, and the multiplexing function set of the triggered key is a non-empty set, the target function according with the user operation intention can be matched from the multiplexing function set of the key according to the type of the triggered key and the target operation performed on the key, and then the target function can be executed, so that the response to the triggering key operation is realized.

In an exemplary implementation manner, to accurately determine the function to be executed after the key is triggered, the display device may maintain a second preset list, where the correspondence between the code value and the function is clearly recorded in the second preset list, where the function category in the second preset list includes the initial preset function of each key and the preset multiplexing function included in the multiplexing function set. It can be understood that the type of the key triggered by the user, the type of the target operation (such as clicking, double clicking, long pressing, etc.) of the key, and the type of the interface currently displayed by the display device all affect the input code value corresponding to the key, so that the corresponding relationship between different code values and functions thereof is stored by using the second preset list, and the corresponding executed functions can be queried according to the obtained code values in actual use.

As an example description, assume that the second preset list stores 3 kinds of correspondence relations, which are { code value a, home function }, { code value B, return to the previous level }, { code value C, display menu page }, respectively. When the display equipment receives double-click operation on the Menu key, inquiring the type of the interface currently displayed by the display, if the type of the interface is detected to be a video playing interface and the first preset list does not comprise the video playing interface, acquiring a code value as a code value C, and executing a function of displaying a Menu page (namely an initial preset function) according to a third corresponding relation; when the display device receives a double-click operation on a Menu key, if the interface type is detected to be a Menu page and the first preset list comprises the Menu page, executing a Home function (namely a first preset multiplexing function) of returning one key to a system homepage according to a first corresponding relation according to the Menu key type and the double-click operation on a target of the Menu key, wherein the acquired code value is a code value A; when the display device receives a clicking operation on the Menu key, if the interface type is detected to be a Menu page and the first preset list includes a Menu page, according to the key type being the Menu key and the target operation on the Menu key being a click, the acquired code value being the code value B, executing a function of returning to the previous Menu (namely, a second preset multiplexing function) according to the second corresponding relation.

In an exemplary implementation, when the display device receives a target operation on a key, if the current interface type belongs to a preset interface type in a first preset list, performing code value conversion by using a preset conversion algorithm according to the type of the key and the target operation on the key so as to obtain a matched code value; if the current interface type is not contained in the first preset list, code value conversion is not needed, and the default code value of the triggered key is directly obtained. After the code value is obtained, the key function mapping can be realized according to the corresponding relation.

In the foregoing embodiment, it is shown that the code value is converted and acquired according to the key type and the target operation on the key, and then the corresponding relationship between the code value and the function recorded in the second preset list is utilized to match the converted code value, so as to query the target function that is triggered to be executed. It should be noted that, the determination manner of the target function is not limited to the embodiment of the present application.

It should be noted that, the key multiplexing function shown in the embodiment of the present application is merely exemplary, and a user can flexibly set and adjust the key multiplexing function according to factors such as personal wish, function requirement, key operation habit, etc. in practical application, different trigger forms of the same key and different key types can trigger and execute different functions. The original display device only supports the initial preset functions of N keys, after the key multiplexing functions are set, when the preset interface types are displayed, the function dimensions of the N keys are obviously expanded, even all key functions of the remote controller can be covered, and the multiplexing functions of the keys are combined and overlapped to meet the control intention of a user on the display device in a more diversified and more complex mode. In addition, the local keys of the display device are sequentially arranged, and the associated functions are similar to each other, such as volume + and volume-adjacent, channel + and channel-adjacent, source key (corresponding to a confirm key in the example) and Menu key (corresponding to a cancel/return key in the example), so that the normal operation habit of the user is met, the user is convenient to recognize and operate according to the intention, and in a scene that the remote controller is unavailable, the user is supported to control the display device through the local keys, and the practicability and applicability of the local keys of the display device are improved.

In an exemplary implementation manner, referring to the technical description of the foregoing related embodiments, as shown in fig. 5, an embodiment of the present application provides a key multiplexing method executed by a display device, more specifically, an execution subject of the method is a controller 250, and the method includes the following program steps:

step S101, inquiring the type of the interface currently displayed by the display when the target operation of the key is received.

Step S102, judging whether the first preset list is an empty list. If the list is not empty, step S103 is executed, and if the list is empty, step S107 and step S108 are executed. The first preset list is maintained by display equipment and comprises preset interface types supporting key multiplexing functions, and the multiplexing function set comprises preset multiplexing functions corresponding to triggering operations of the keys.

Step S103, judging whether the interface type is contained in the first preset list. If yes, step S104 is executed, and otherwise, step S107 and step S108 are executed.

Step S104, judging whether the multiplexing function set of the key is an empty set. If the set is an empty set, step S107 and step S108 are executed, and if the set is a non-empty set, step S105 and step S106 are executed.

Step S105, according to the type of the key and the target operation, obtaining a matched target function from the multiplexing function set of the key.

Step S106, executing the target function.

Step S107, the initial preset function of the key is obtained.

Step S108, executing the initial preset function.

The target function is a preset multiplexing function matched with a key triggered by target operation input by a user, and the preset multiplexing function is an extended function which is preset by the user and is executed when the preset interface type is displayed, except for an initial preset function. The initial preset function is a function executed when a default key is triggered when the display device leaves the factory, for example, the initial preset function of the Menu key is used for displaying a Menu page, and after the preset multiplexing function of the Menu key is set by a user, when a preset interface type is displayed, for example, a corresponding target function is returned to the previous stage/step when the Menu key is clicked. The preset multiplexing functions of the same key may be zero or at least one, and may be specifically determined according to a set triggering operation, for example, for a Menu key, if a single click on the Menu key is set, the previous stage/step is returned, if the Menu key is pressed for a long time, the system homepage is returned, and when the Menu key is double-clicked, the application center is displayed, the preset multiplexing functions of the Menu key include three kinds, and the multiplexing function set thereof is non-null. Therefore, according to the type of the triggered key and the target operation actually input by the user, the target function meeting the user key operation intention can be matched from the multiplexing function set of the key.

Because the first preset list and the multiplexing function set of the key can be changed along with the adjustment of the user setting, whether the first preset list is an empty list or not and whether the multiplexing function set is an empty set or not can be judged first, if at least one of the first preset list and the multiplexing function set is an empty set, the key multiplexing condition is not met, and the initial preset function is required to be executed when the key is triggered. In the above steps S102 and S103, and step S104, as to whether or not the judgment condition of the key multiplexing condition is satisfied, the judgment conditions may be executed simultaneously or in sequence in the specific implementation, and the present application is not limited to this.

In an exemplary implementation manner, referring to the technical description of the foregoing related embodiments, as shown in fig. 6, an embodiment of the present application provides another key multiplexing method executed by a display device, more specifically, an execution subject of the method is a controller 250, and the method includes the following program steps:

step S201, when receiving the target operation of the key, inquiring the type of the interface currently displayed by the display.

Step S202, judging whether the first preset list is an empty list. If the list is not empty, step S203 is executed, and if the list is empty, step S207 and step S208 are executed. The first preset list is maintained by display equipment and comprises preset interface types supporting key multiplexing functions, and the multiplexing function set comprises preset multiplexing functions corresponding to triggering operations of the keys.

Step S203, judging whether the interface type is contained in the first preset list. If yes, step S204 is executed, and otherwise, step S207 and step S208 are executed.

Step S204, judging whether the multiplexing function set of the key is an empty set. If the set is empty, step S207 and step S208 are executed, and if the set is not empty, step S205 and step S206 are executed.

Step S205, calculating a first target code value according to the key and the target operation by using a preset conversion algorithm.

Step S206, inquiring a target function corresponding to the first target code value in a second preset list, and executing the target function; the corresponding relation between the code value and the function is recorded in the second preset list.

Step S207, obtaining a second target code value corresponding to the key.

Step S208, inquiring an initial preset function corresponding to the second target code value in a second preset list, and executing the initial preset function.

In an exemplary implementation, since the second preset list is associated with the first preset list and the multiplexing function set of each key, the second preset list is also adaptively changed and updated, for example, if the multiplexing function set of the key a is an empty set, only the correspondence between the initial preset function of the key a and the default code value thereof is recorded in the second preset list; when the user fills a non-empty multiplexing function set for the key A, recording the corresponding relation between the initial preset function of the key A and the default code value of the key A and the corresponding relation between each preset multiplexing function in the set and the converted and calculated code value in a second preset list; when the user cancels or modifies a certain preset multiplexing function of the key a, the second preset list also needs to delete or change the corresponding relation of the preset multiplexing function of the key a synchronously. For another example, when the first preset list is an empty list, that is, the user does not set any preset interface type supporting the key multiplexing function, the second preset list only records the corresponding relation between the initial preset function of each local key and the default code value thereof; when the first preset list is changed into a non-empty list, the second preset list can be synchronously updated according to the setting condition of the user on the multiplexing function of the local key.

The second preset list at least comprises the corresponding relation between the initial preset function of each local key and the default code value of each local key, so that the second preset list is necessarily a non-empty list. The display device may maintain and update the second preset list according to the first preset list and the setting condition of the user on the key multiplexing function. In the above steps S202 and S203, and step S204 are the discrimination conditions for determining whether the key multiplexing condition is satisfied, and in a specific implementation, these discrimination conditions may be executed simultaneously, or the discrimination may be performed in a sequential order, which is not limited in the present application.

In this embodiment, when the display device displays the preset interface type, the conversion of the key code values can be completed under the condition that the user does not feel, and the target function corresponding to the current scene is matched according to the corresponding relationship between the code values of the keys and the functions recorded in the second preset list and the converted first target code value. If the first preset list is an empty list, or the current display interface does not belong to any preset interface type, or the multiplexing function set of the triggered key is an empty set, directly acquiring a default second target code value of the key, and matching a function corresponding to the second target code value in the second preset list, namely, the initial preset function of the key. The preset multiplexing function of each key can be multiple, but the initial preset function is unique, each code value in the second preset list has global uniqueness, the code value is associated with the type of the key, the triggering operation of the key and the interface display scene, the code values are different, and the corresponding triggering executing functions are also different.

In an exemplary implementation, after the controller 250 obtains the code value, the function corresponding to the code value is matched according to the second preset list, and then a control instruction is issued to the corresponding module at the bottom layer according to the category of the function, for example, the function a is to reduce the volume, the control instruction a is issued to the volume module of the television speaker or the external power amplifier, and the volume module responds to the control instruction a, and then reduces the volume value of the audio output by the television speaker or the external power amplifier.

In other exemplary implementations, after the controller 250 obtains the code value, the target module may be determined according to the code value, and then the code value is sent to the target module, and the target module identifies the code value and then performs the corresponding function. For example, if the code value B belongs to the channel code value, the controller 250 sends the code value B to the channel module at the bottom layer, the channel module identifies the code value B, and if the channel module identifies that the function corresponding to the code value B is to adjust the channel backward, the channel module controls the UI to jump to the next channel of the current channel. The specific implementation manner of the key function execution is not limited to the embodiment of the present application.

In the key multiplexing mechanism provided by the application, corresponding functional operations are matched and executed according to factors such as interface display scenes of display equipment, key types and trigger operations executed on keys, so that the television local keys are not limited to initial preset functions, the function multiplexing of each local key under different interface display scenes is expanded, multiplexing functions of all keys can be combined, a more diversified local key control mode is provided when a remote controller is not available, the use of users is facilitated, the number of keys of the television is not required to be changed, and the functionality, convenience and practicability of the television local keys are improved.
