In the displayed data list, the options in the list correspond to the data in the data set one by one. The user can instruct the display device to select a certain option through the operation of moving the focus, and the display device responds to the operation of moving the focus by the user, displays the selector on the option where the focus is located, and further highlights the option selected by the user. The display style of the selector is not limited in the present application.

Illustratively, the display device may obtain a data set composed of device information data in the local area network through the devices in the local area network, and present the devices in the form of a device list. For another example, the display device may obtain a data set of network access point data by scanning nearby network access points (wireless AP devices) and present the network access points in the form of a list of network access points.

In the following description, a network connection through a WiFi list is taken as an example for explanation, but it should be understood that the WiFi list is only one of various data lists, and the type and data of the data list are not limited to the scheme.

Fig. 5 is a schematic diagram of a WiFi list shown in the present application according to an exemplary embodiment, as shown in fig. 5, a WiFi list is presented in a user interface of a display device, where the WiFi list includes a preset number of WiFi options a-E arranged according to signal strength, different WiFi options correspond to different WiFi access point data, and the WiFi access point data is obtained by a WiFi module of the display device scanning nearby wireless AP devices based on a WiFi detection technology, where the wireless AP devices include, but are not limited to, a wireless router, a terminal that opens a WiFi hotspot, and the like. Each WiFi access point data includes a device name, a MAC address, a WiFi signal strength, a WiFi signal channel, a signal frame type of the wireless AP device. Typically, the WiFi option in the WiFi list shows the device name of the corresponding wireless AP device. When displaying the WiFi list, the user can select a certain WiFi option by moving the focus position, and the option at the focus is the selected option, which is generally called the focus option. For example, in the WiFi list shown in fig. 5, WiFi option C is the focus option, and the order of the bits of the focus option in the list is 3 rd, that is, it is displayed at the third display position of the list. When the user inputs the focus options, the user enters the corresponding WiFi connection interface, and the user can input a WiFi password through the WiFi connection interface and trigger the display equipment to access the corresponding wireless AP equipment.

In some embodiments, the display device needs to update the list in the user interface in real time when the list data changes, for example, when the scanned device data changes, the device list needs to be updated in real time according to the latest device data, and when the detected number of network access points and/or the signal strength sequence changes, the corresponding list needs to be updated in real time according to the latest network access point data.

Fig. 6 is a schematic diagram of a WiFi list according to an exemplary embodiment of the present application, which is specifically a user interface obtained by refreshing the WiFi list interface shown in fig. 5. As shown in fig. 6, compared to the WiFi list shown in fig. 5, WiFi options and the arrangement order of the options constituting the WiFi list are changed, and the display position of the focus option and its corresponding WiFi access point data are changed. Specifically, in the WiFi list shown in fig. 6, the WiFi options arranged according to the signal strength are WiFi options F-J in sequence, the focal option is WiFi option I, and the bit sequence of the focal option in the list is the 4 th bit, that is, the focal option is displayed at the fourth display position of the list.

In some embodiments, the list displayed in the user interface is a visual portion of the complete list. In other words, the complete list includes, in addition to the options displayed within the viewable area of the user interface, options that are hidden outside the viewable area of the user interface. The user can drag the option hidden outside the visible area to the visible area by inputting the operation of moving the focus. For example, the hidden option at the lower part of the complete list is dragged into the visible area through the operation of moving the focus downwards, and the hidden option at the upper part of the complete list is dragged into the visible area through the operation of moving the focus upwards.

Fig. 7 is a schematic diagram of a WiFi list shown in the present application according to an example embodiment. FIG. 7 shows a complete list corresponding to the WiFi list shown in FIG. 6, further showing WiFi options hidden outside the user interface view area. As shown in fig. 7, the complete list includes WiFi options a-E, where WiFi options F-J form the visible portion of the complete list, and the remaining options are hidden outside the visible area.

In some embodiments, the process of updating the list in the user interface by the display device when the list data changes includes an updating process of the complete list, and further includes a process of determining a visualization portion of the new complete list and controlling the visualization portion to be displayed in the visual area of the user interface.

In some embodiments, when the display device needs to present data in a certain data set in the user interface in a list form, a list is displayed in the user interface according to the data set, where the list includes at least one option, and different options respectively correspond to different data in the data set. For example, the aforementioned data set may be a set formed by the wireless access point data shown in the above embodiments, and the scenario that the set needs to be presented in the user interface in the form of a list includes but is not limited to when the user inputs an instruction indicating to scan nearby WiFi, when a "wireless local area network" control in the setting interface is operated, and the like. When the list is displayed, when the data composition and/or the data arrangement sequence of the data set are/is changed, the display device updates the list according to the original focus option and the changed data set, wherein the original focus option refers to an option selected before the list is updated, or the original focus option refers to an option where a focus is located when the data set is changed. If the changed data set still includes data corresponding to the original focus option, after the list is updated, the display position of the new focus option and the corresponding data are consistent with the display position of the original focus option and the corresponding data. With the foregoing example, when the wireless access point data scanned by the display device increases, decreases, or the data itself changes (e.g., WiFi strength changes), the list needs to be updated.

Therefore, after the list is refreshed, the focus is still positioned on the data corresponding to the original focus option, and the position of the focus option is not changed. Furthermore, the user does not need to manually traverse the list to reselect the data corresponding to the original focus option, so that the operation times of the user are reduced, and the user experience is improved. For convenience of explanation, in the following embodiments, a data set before change is referred to as a first data set, and a data set after change is referred to as a second data set. It should be understood that the difference between the first data set and the second data set includes data composition and/or data arrangement order.

In some embodiments, the pre-update list is a visualized portion of a first complete list generated from the first data set, the options in the first complete list corresponding one-to-one to the data in the first data set; the updated list is a visual part of a second complete list generated according to a second data set, and options in the second complete list correspond to data in the second data set one by one; the visualization portion includes up to a preset number of options displayed in a viewable area of the user interface.

Fig. 8 is a schematic diagram illustrating a list update scenario according to some example embodiments. As shown in fig. 8, a first complete list 810 is generated from the first data set, including option 1-option 10, which correspond to 10 data in the first data set, respectively; the visual part of the first complete list 810 comprises options 3-8, options 1 and 2 are hidden at the upper side of the visual area, and options 9 and 10 are hidden at the lower side of the visual area; the focus option before the list update is option 6, the focus option is displayed at the fourth display position of the visual area, and the data corresponding to the focus option is data a. For convenience of explanation, in the following embodiments, the focus option before the list update is referred to as an original focus option, and data corresponding to the original focus option is referred to as original focus data. Then, in the example shown in fig. 8, the original focus option is option 6 and the original focus data is data a. With continued reference to FIG. 8, a second complete list 820 is generated from the second data set, including option 1-option 15, which correspond to 15 data in the second data set, respectively; the visualization portion of the second complete list 820 includes options 9-14, options 1-8 are hidden on the upper side of the viewable area, and option 15 is hidden on the lower side of the viewable area; the focus option after the list update is option 12, the focus option is displayed at the fourth display position of the visual area, and the data corresponding to the focus option is data a.

As can be seen from the list update process shown in fig. 8, before and after the list update, the display position of the focus option and its corresponding data are not changed. In other words, after the list is updated, the display position and the corresponding data of the new focal option are consistent with the display position and the corresponding data of the original focal option.

In some embodiments, the process of updating the list by the display device according to the original focus option and the second data set may include: the method comprises the steps of firstly obtaining an original focus position and original focus data, wherein the original focus position can be a display position of an original focus option in a visual area, and also can be a bit sequence in a visual part of the original focus option, and the original focus data is data corresponding to the original focus option. For example, in the example shown in fig. 8, the original focus position is the fourth option display position in the visible area, and is also the fourth option in all the visible options, and the original focus data is data a. And then generating a second complete list according to the second data set, and judging whether the second complete list contains an option corresponding to the original focus data or not, or judging whether the second data set contains the original focus data or not. If the second complete list comprises options corresponding to the original focus data or the second data set comprises the original focus data, determining continuous preset number of options comprising the options corresponding to the original focus data in the second complete list as a visual part of the second complete list, and determining the options corresponding to the original focus data as new focus options; and displaying the visual part of the second complete list in the visual area, and displaying the new focus option in the original focus position. In the example shown in fig. 8, the new focus option is the option in the second complete list corresponding to the original focus data "data a".

In the above embodiment, the bit sequence of the option corresponding to the original focus data in the visualized part of the second complete list is the same as the bit sequence of the original focus option in the visualized part of the first complete list. In this way, it is ensured that the new focus option is displayed at the original focus position.

In a more specific implementation manner, determining, as a visualization part of the second complete list, a preset number of consecutive options in the second complete list that include an option corresponding to the original focus data may include: determining a start option and an end option according to the display position of the original focus option in the visual area, or according to the bit sequence of the original focus option in the visual part of the first complete list, and the bit sequence of the option corresponding to the original focus data in the second complete list and the preset number (namely the preset number) of options in the visual area, and determining the start option, the end option and the option between the start option and the end option as the visual part of the second complete list. Taking fig. 8 as an example, the original focus option "option 6" is displayed in 4 option display bits in the visible area, the number of options preset in the visible area is 6, the original focus data "data a" corresponds to option 12 in the second complete list, based on these parameters, the starting option is determined as option 9, the ending option is determined as option 14, and then the visualized part of the second complete list is determined as options 9-14.

In some embodiments, if the second complete list does not satisfy the condition for making the bit sequence of the original focus data corresponding option in the visualized part of the second complete list the same as the bit sequence of the original focus option in the visualized part of the first complete list, the options in the second complete list are reordered so that the second complete list satisfies the condition for making the bit sequence of the original focus data corresponding option in the visualized part of the second complete list the same as the bit sequence of the original focus option in the visualized part of the first complete list.

Fig. 9 is a schematic diagram illustrating a list update scenario according to some example embodiments. As shown in fig. 9, the first complete list 910 is generated according to the first data set, and the composition and arrangement order of the options of the first complete list 910 are the same as those of the first complete list 810 shown in fig. 8, which is not repeated herein. The original focus option is also option 6, the original focus option is also displayed in the fourth option display position of the visible area, and the original focus data is also "data a". Unlike fig. 8, the second complete list 920 includes options 1-15, where the option corresponding to the original focus data "data a" is option 15. Based on the scenario shown in fig. 9, the original focus option "option 6" is displayed in 4 option display bits in the visible area, the number of options in the visible area is 6, but since the last option in the option list corresponding to the original focus data "data a" in the second complete list 920 is the last option, it is impossible to intercept consecutive 6 options from the second complete list 920 and at the same time, it is guaranteed that the option corresponding to the original focus data "data a" is the 4 th option in the 6 th option, so that the second complete list 920 does not satisfy the condition for making the bit order of the original focus data corresponding option in the visualized portion of the second complete list be the same as the bit order of the original focus option in the visualized portion of the first complete list.

Based on the scenario shown in fig. 9, the options in the second complete list 920 may be reordered, and the reordered second complete list 920 includes 6 options consecutively while ensuring that the option corresponding to the original focus data "data a" is the 4 th option in the 6 options. Fig. 10 is a diagram illustrating a list update scenario according to an exemplary embodiment of the present application, which shows a reordered second complete list 930 based on fig. 9. As shown in fig. 10, compared to the second complete list 920 shown in fig. 9, in the second complete list 930 shown in fig. 10, data corresponding to the option 12 and the option 15 are exchanged, so that the original focus data "data a" in the second complete list 930 is the option 12. In this way, the visualization part of the second complete list is determined as options 9-14, wherein option 12 corresponds to the original focus data "data a" and is thus determined as the new focus option.

In some embodiments, the process of updating the list by the display device according to the original focus option and the second data set may include: first, the original focus position and the original focus data are obtained. And then generating a second complete list according to the second data set, and judging whether the second complete list contains an option corresponding to the original focus data or not, or judging whether the second data set contains the original focus data or not. If the second complete list does not contain the option corresponding to the original focus data or the second data set does not contain the original focus data, judging whether the bit sequence of the last option in the second complete list is smaller than the bit sequence of the original focus option in the first complete list; if the bit sequence of the last option in the second complete list is smaller than the bit sequence of the original focus option in the first complete list, determining a preset number of options behind the bit sequence in the second complete list as a visual part of the second complete list, and determining the last option as a new focus option; the visual portion of the second complete list is displayed in the visual area and the new focus option is displayed in the last display position in the visual area. Therefore, when the second complete list does not contain the option corresponding to the original focus data, the focus is updated to the option closest to the original focus option, so that the user can continue the operation of updating the list conveniently, repeated operation is avoided, and the user experience is improved.

Fig. 11 is a schematic diagram illustrating a list update scenario according to some example embodiments. As shown in fig. 11, a first complete list 111 is generated from the first data set, including option 1-option 15, which respectively correspond to 15 data in the first data set; the visualization part of the first complete list 111 comprises options 9-14, options 1-8 are hidden on the upper side of the visual area, and option 15 is hidden on the lower side of the visual area; the focus option before the list update is option 13, which is displayed in the fifth option display bit of the visible area, and the data corresponding to the focus option is "data a". A second complete list 112 is generated from the second data set, including option 1-option 10, which correspond to 10 data in the second data set, respectively, none of the data corresponding to options 1-option 10 being "data a". In this example, since the last option in the second complete list 112 is option 10, whose bit sequence is smaller than that of the original focused option (option 13) in the first complete list 111, the next 6 options (options 5-10) in the second complete list 112 are determined as the visual part of the second complete list, and option 10 is determined as the new focused option, which is displayed at the last option display bit in the visual area.

In some embodiments, the process of updating the list by the display device according to the original focus option and the second data set may include: first, the original focus position and the original focus data are obtained. And then generating a second complete list according to the second data set, and judging whether the second complete list contains an option corresponding to the original focus data or not, or judging whether the second data set contains the original focus data or not. If the second complete list does not contain the option corresponding to the original focus data or the second data set does not contain the original focus data, judging whether the bit sequence of the last option in the second complete list is smaller than the bit sequence of the original focus option in the first complete list; and if the bit sequence of the last option in the second complete list is greater than or equal to the bit sequence of the original focus option in the first complete list, determining a new focus option according to the bit sequence of the original focus option in the first complete list, wherein the bit sequence of the new focus option in the second complete list is the same as the bit sequence of the original focus option in the first complete list. Determining continuous preset number of options containing the new focus options in the second complete list as a visual part of the second complete list; and displaying the visual part of the second complete list in the visual area, and displaying the new focus option in the original focus position. Therefore, when the second complete list does not contain the option corresponding to the original focus data, the focus is updated to the option closest to the original focus option, so that the user can continue the operation of updating the list conveniently, repeated operation is avoided, and the user experience is improved.

In the above embodiment, the bit sequence of the new focused option in the visualized part of the second complete list is the same as the bit sequence of the original focused option in the visualized part of the first complete list. In this way, it is ensured that the new focus option is displayed at the original focus position. It should be noted that, in the above embodiment, the continuous preset number of options including the new focus option in the second complete list is determined as the visualization part of the second complete list, and a specific implementation manner of the embodiment may refer to the foregoing description of fig. 8, which is not repeated herein.

Fig. 12 is a schematic diagram illustrating a list update scenario according to some example embodiments. As shown in fig. 12, a first complete list 121 is generated from the first data set, including option 1-option 15, which respectively correspond to 15 data in the first data set; the visualization part of the first complete list 121 comprises options 9-14, options 1-8 are hidden on the upper side of the visual area, and option 15 is hidden on the lower side of the visual area; the focus option before the list update is option 13, which is displayed in the fifth option display bit of the visible area, and the data corresponding to the focus option is "data a". A second complete list 122 is generated from the second data set, including option 1-option 20, which correspond to 20 data in the second data set, respectively, none of the data corresponding to options 1-option 20 being "data a". In this example, since the last option in the second complete list 122 is option 20, and the bit sequence thereof is greater than that of the original focused option (option 13) in the first complete list, option 13 in the second complete list is determined as the new focused option, and the consecutive 6 options (options 9-14) containing option 13 are determined as the visualization part of the second complete list, and the new focused option is displayed in the fifth option display bit of the visualization area.

In some embodiments, the arrangement data of the items in the first complete list is the same as the arrangement order of the data in the first data set, and the arrangement data of the items in the second complete list is the same as the arrangement order of the data in the second data set. Taking the first data set and the second data set composed of the wireless access point data as an example, the wireless access point data in the set are sorted according to the wireless signal strength, and meanwhile, the options in the list generated according to the set are also sorted according to the wireless signal strength.

In some embodiments, the scenario that triggers the first data set to change, thereby forming the second data set, may be different based on the data source and the data content.

For example, for a data set composed of wireless access point data, when the wireless signal strength of a wireless AP device scanned by a display device changes, the wireless signal strength data included in the corresponding wireless access point data changes, and the order of the wireless access point data in the first data set changes, so as to form a second data set with a new order. Or, when a certain wireless AP device is turned off or a signal is too weak to cause the display device to scan the wireless AP device, the wireless access point data in the first data set will decrease, and when a certain wireless AP device is turned on to cause the display device to scan a new wireless AP device, the wireless access point data in the first data set will increase. It should be understood that the decrease, increase or data replacement of the wireless access point data in the data set, which occurs in the case of the same amount of data, will also cause the data arrangement order in the data set to change.

For another example, for a data set composed of data acquired from a server, when receiving a new data sent by the server or an instruction to delete an original data, it means that the original data set changes and forms a new data set different from the original data set. When a new data set sent by the server is received, the fact that the original data set changes means that the new data set is the changed data set.

According to the display device provided in the above embodiment, an embodiment of the present application further provides a list updating method, as shown in fig. 13, the method may include:
