For example, people related pictures may be clustered in a people folder, and mountains related pictures may be clustered in a mountains folder. The embodiment of the application does not limit the clustering mode of the files, and in the practical application process, the user can configure the folders according to the requirements.

The user executes step S102 to select the folder;

the implementation manner of selecting the folder by the user is not limited in this embodiment.

For example, in the embodiment illustrated in fig. 7, the display interface is configured with a focus, the focus is configured to be moved in a controlled manner, and the user can control the focus to move through the remote controller so as to complete the selection of the folder.

For another example, in one possible embodiment, the controller may be equipped with voice assistant software, and the user may complete the selection of the folder via voice instructions.

In the practical application process, the implementation manner of selecting the folder by the user can be, but is not limited to, the two modes.

In response to a user selection of a folder, the controller is configured to execute step S103 to sequentially traverse a thumbnail list corresponding to the folder selected by the user;

the order in which the controller traverses the thumbnail list is not limited in this application;

for example, in a feasible embodiment, the files in the folders are arranged in descending order according to the names of the files, in which case the controller may sequentially traverse the thumbnail list corresponding to the folder selected by the user according to the ordering of the names of the files, and determine whether the thumbnail list records the thumbnail matching the file.

For example, in one possible embodiment, the folder contains 8 file partitions: file 1, file 2, file 3, file 4, file 5, file 6, file 7, and file 8; the result that 8 files are arranged in descending order of file names in the folder can be referred to in table 1;

TABLE 1

The controller firstly judges whether the thumbnail list records the thumbnail matched with the file 1; then, whether or not the thumbnail image … … matching with the file 2 is recorded in the thumbnail image list is judged, and whether or not the thumbnail image matching with the file 8 is recorded in the thumbnail image list is judged.

For another example, in a feasible embodiment, the files in the folders are arranged in descending order according to the modification time of the files, in which case the controller may sequentially traverse the thumbnail list corresponding to the folder selected by the user according to the order of the modification time, and determine whether the thumbnail list records the thumbnails matched with the files.

In the practical application process, the sequence of traversing the thumbnail list by the controller can be, but is not limited to, the two modes, and the applicant does not limit the invention too much.

the controller executes step S11 to traverse the thumbnail list;

the order of traversing the thumbnail list may be referred to above in implementations and applicant does not reiterate here.

The controller executes step S12 to determine whether or not the thumbnail of the file is recorded in the thumbnail list;

the realization mode of judging whether the thumbnail of the file is recorded in the thumbnail list is various;

for example, in one possible embodiment, a file and a thumbnail of the file may be configured with corresponding identifications. The controller searches the thumbnail list for the thumbnail matched with the identification based on the identification of the file;

for example, in one possible embodiment, 4 thumbnails are recorded in the thumbnail list, respectively: thumbnail 1, thumbnail 2, thumbnail 3, thumbnail 4, specific thumbnail list can refer to table 2;

TABLE 2

Sequence number	File name	Identification mark	Remarks
				1	Thumbnail 1	Sign 1
2	Thumbnail image 2	Sign 2
				3	Thumbnail 3	Sign 3
4	Thumbnail image 4	Sign 4

The controller traverses the table 2 based on the identification (identification 1) of the file 1, and determines that the thumbnail image of the file 1 is recorded in the table 2; then, the controller traverses table 2 based on the identification (identification 2) of file 2, determines that the thumbnail image … … with file 2 is recorded in table 2, and the controller traverses table 2 based on the identification (identification 5) of file 5, determines that the thumbnail image with file 2 is not recorded in table 2.

For another example, in order to reduce the amount of data stored in the thumbnail list, in a possible embodiment, the file name may be used as an identifier, and the specific thumbnail list may refer to table 3;

TABLE 3 Table 3

Sequence number	File name	Remarks
			1	File 1.Png
2	File 2.Png
			3	File 3.Png
4	File 4.Png

For another example, in some feasible embodiments, the thumbnail list and the file may be stored in the same folder, in which case the thumbnail is not allowed to use the same name as the file, and based on this embodiment of the application, a naming manner of the thumbnail is shown, where the specific naming manner is that the name of the thumbnail=the storage address of the file+the name of the file, and the specific thumbnail list may refer to

Table 4;

sequence number	File name	Remarks
			1	Photo_person_file1. Png
2	Photo_person_file2.png
			3	Photo_character_file3.png
4	Photo_person_file4.png

The beneficial effects of the above nomenclature will be described in detail in the schemes that follow.

In the practical application process, the implementation manner of determining whether to record the thumbnail of the file in the thumbnail list may be, but is not limited to, the above-mentioned several manners, and the applicant does not make any limitation here.

If the thumbnail of the file is recorded in the thumbnail list, the controller executes step S13 to control the display to display the thumbnail at the file display position, and the controller continues to execute step S11.

The file display position is determined by the icon size set by the user and the size of the display interface. Fig. 9 is a schematic diagram of a display presentation interface shown according to one possible embodiment. In the embodiment shown in fig. 9, the user-set icon is displayed in the form of an oversized icon, at this time, 8 icons may be simultaneously displayed on the display interface of the display, and the display interface is divided into 4*2 areas, where each area is a display position of one file. Region a in fig. 9 is a display region of document 1.

If the thumbnail of the file is not recorded in the thumbnail list, the controller executes step S14 to control the display to display a preset icon at the file display position, and the controller continues to execute step S11.

The scheme shown in the embodiment of the present application is not limited to the style of the preset icon.

The icons shown in folders 4, 5, 7, 8 in fig. 9 are merely exemplary patterns showing one preset icon, and the patterns of the preset icons during actual application may be, but are not limited to, the patterns shown in fig. 9.

If the thumbnail list records the thumbnail of the file, the controller is configured to execute step S104 to control the display to display the thumbnail at the file display position;

if the thumbnail list does not record the thumbnail of the file, the controller is configured to execute step S105 to control the display to display a preset icon at the file display position;

the operation of the display device shown in this embodiment will be described in detail with reference to specific examples.

In a feasible embodiment, the user selects the folder 1, wherein the folder 1 comprises 8 files, namely, a file 1, a file 2, a file 3, a file 4, a file 5, a file 6, a file 7 and a file 8; the thumbnail list corresponding to the folder 1 is the thumbnail list 1. In response to a user selecting the folder 1, the controller traverses the thumbnail list 1 based on the name of the file 1, determines that the thumbnail list 1 records the thumbnail of the file 1, and controls the display to display the thumbnail of the file 1, wherein the display interface of the display can refer to the interface 11 in fig. 10; then, the controller traverses the thumbnail list 1 based on the name of the file 2, determines that the thumbnail list 1 records the thumbnail of the file 2, and controls the display to display the thumbnail of the file 2, wherein the display interface of the display can refer to the interface 12 in fig. 10; then, the controller traverses the thumbnail list 1 based on the name of the file 3, determines that the thumbnail list 1 does not record the thumbnail of the file 3, and controls the display to display the preset icon, at this time, the display interface of the display may refer to the interface 13 … … in fig. 10, the controller traverses the thumbnail list 1 based on the name of the file 8, determines that the thumbnail list 1 does not record the thumbnail of the file 8, and controls the display to display the preset icon, at this time, the display interface of the display may refer to the interface 14 in fig. 10.

The description of the embodiment is thus completed.

The technical proposal provided by the implementation is initially designed in such a way that when the file to be displayed is a media file, the file can be displayed in the form of a thumbnail so as to play a role in prompting a user. If the file type is a non-media type, the controller continues to traverse the thumbnail list, which is a waste of computing resources of the controller, and based on the scheme shown in the embodiment of the application, the controller can pre-judge whether the file type is a media type, and then determine whether to traverse the thumbnail list according to the judging result, so that the data processing capacity of the controller is reduced.

The embodiment of the application shows a display device, and a structural block diagram of the display device may refer to fig. 5, where a flow chart of interaction between a display and a controller in the display device may refer to fig. 11.

the display manner of the downloaded folder may refer to the above embodiment, and will not be described herein.

The user executes step S202 to select the folder;

the implementation manner of selecting the folder by the user may refer to the above embodiment, and will not be described herein.

In response to a user selection of a folder, the controller is configured to execute step S203 to sequentially read file types of files stored in the folder;

There are various implementations of reading the file type of the file;

for example, in a viable embodiment, the file type may be read by the suffix of the file name. For example, the file name of the file is "20201126-1.Jpg", and the file type can be determined to be a picture; the file name of the file is '20201126-2. PNG', and the file type can be determined to be a picture; the file name of the file is '20201126-3. AVI', and the file type can be determined to be video; the file name of the file is "20201126-4.Mov", and the file type can be determined to be video.

If the file type is not the media type, the control execution step S204 controls the display to display a preset icon at the file display position;

the media asset types shown in the embodiment of the application include pictures and videos.

The display manner of the preset icons may refer to the above embodiment, and will not be described herein.

In some feasible embodiments, in order to improve the experience of the user, in the embodiment of the present application, the file type icon corresponding to each file type is designed in advance, and the user can learn the type of the file through the file type icon displayed by the display, so as to improve the experience of the user.

The description of the embodiment is thus completed.

The technical proposal provided by the implementation is initially designed in such a way that when the file to be displayed is a media file, the file can be displayed in the form of a thumbnail so as to play a role in prompting a user. In order to further improve the experience of the user, in the technical scheme shown in the embodiment, a thumbnail generating thread is arranged in the controller, and the thumbnail generating thread is used for constructing the thumbnail of the current file when the thumbnail of the current file does not exist in the thumbnail list, so that the files of the media asset type can be displayed in the form of the thumbnail, and the experience of the user is further improved.

The embodiment of the application shows a display device, and a structural block diagram of the display device may refer to fig. 5, where a flow chart of interaction between a display and a controller in the display device may refer to fig. 15.

In response to a user selection of a folder, the file management thread is configured to execute step S301 to sequentially read file types of files stored in the folder;

in the technical scheme shown in the embodiment of the application, the file management thread determines the file type through the name of the file. The implementation manner of reading the file type may refer to the above embodiment, and will not be described herein.

If the file type is a media asset type, the file management thread is configured to execute step S302 to traverse the thumbnail list of the folder;

the implementation of traversing the thumbnail list may be referred to the above embodiments and will not be described herein.

If the thumbnail list does not record a thumbnail of the file, the file management thread is configured to execute step S3031 to invoke the thumbnail generation thread;

in the technical scheme shown in the embodiment of the present application, when a file management thread calls a thumbnail generation thread, a name of a file and a storage address of the file are sent to the thumbnail generation thread.

The thumbnail generation thread is configured to execute step S3041 to construct a thumbnail of the file;

the thumbnail generation thread may find the folder in which the file is located based on the storage location of the file, and then find the file for which the thumbnail is to be constructed based on the name of the file.

The implementation of constructing the thumbnail may employ a thumbnail construction method that is conventional in the art, for example, by constructing the thumbnail through the following steps. (1) The source image (file) is loaded into a PHP (Hypertext Preprocessor ) variable. (2) determining the height and width of the source image. (3) creating a blank thumbnail of the correct size. (4) copying the original image to the blank thumbnail. (5) displaying the thumbnail using the correct content type.

The embodiment is merely an exemplary description of a method for constructing a thumbnail, and a method for constructing a thumbnail in a practical application process may be, but is not limited to, the foregoing method.

In this embodiment, the name of the thumbnail=the storage address+the file name, where the storage address is the storage address of the file corresponding to the thumbnail. The file name is the name of the thumbnail corresponding file. The correspondence between the file and the thumbnail can be constructed by the file name. This is also done based on file names in traversing the thumbnail list.

In response to completion of the construction of the thumbnail, the thumbnail generation thread is configured to perform step S3051 to send an update message to the presentation layer;

in this embodiment, the storage address of the thumbnail and the name of the thumbnail are encapsulated in the update message.

The display layer executes step S3061 to draw the thumbnail based on the data stored in the thumbnail storage address carried by the update message, and the content displayed by the display is converted into the thumbnail by the media resource icon.

The display layer draws the thumbnail based on the data stored in the thumbnail storage address carried by the update message, and the implementation mode of drawing the thumbnail data can adopt an image drawing mode which is conventional in the field.

The display layer executes step S3071 to control the display to display the thumbnail;

and the display layer finds the media asset picture of the file based on the thumbnail name carried by the update message, and then controls the display to withdraw the media asset icon to display the constructed thumbnail.

If the thumbnail list does not record the thumbnail of the file, the file management thread S3032 sends a preset icon address to the presentation layer;

in the scheme shown in the embodiment of the present application, the preset icon may be shared by multiple folders, so that the display picture may be stored in an independent storage area, so as to ensure that when one folder is deleted, the preset icon may still provide services for other folders.

In contrast, the preset icon list serves one folder. When the folder is deleted, the thumbnail list corresponding to the folder is also meaningless. Thus, the thumbnail list may be stored in its corresponding folder, specifically, the generated thumbnail is placed under the root directory of the disk.

The presentation layer executes step S3042 to draw a preset icon based on the data stored in the preset icon address;

the display layer draws the implementation manner of the preset icon based on the data stored in the preset icon address, and the implementation manner of drawing the thumbnail data can adopt an image drawing manner which is conventional in the art.

Responding to the selection of the user on the folder 3, reading the suffix of the name of the file 1 by the file management thread, and judging that the file 1 is a picture through the suffix of the name of the file 1; the file management thread traverses the thumbnail list 3 based on the name of the file 1, determines that the thumbnail list 3 records the thumbnail of the file 1, and sends the storage address of the thumbnail to the presentation layer. The presentation layer presents the drawn thumbnail on the display, at which point the presentation interface of the display may refer to interface 31 in fig. 17. Then, the file management thread reads the suffix of the name of the file 2, and judges that the file 3 is a picture through the suffix of the name of the file 2; the file management thread traverses the thumbnail list 3 based on the name of the file 2, determines that the thumbnail list 3 does not record the thumbnail of the file 3, and sends the storage address of the picture icon to the presentation layer. The display layer displays the drawn picture icon on the display, at this time, the display interface of the display can refer to interface 32 … … in fig. 17, then, the file management thread reads the suffix of the name of file 8, judges that file 2 is an installation package type file according to the suffix of the name of file 2, and controls the file management thread to send the storage address of the installation package icon to the display layer. The presentation layer presents the drawn installation package icon on the display, at which point the presentation interface of the display may refer to interface 33 in fig. 17. When the file management system determines that the thumbnail list 3 does not record the thumbnail of the file 3, the file management thread pulls up the thumbnail construction thread, sends the storage address of the file 2 to the thumbnail construction thread, and constructs the thumbnail by the data stored in the storage address by the cable map construction thread. And when the construction of the thumbnail is completed, the thumbnail construction thread sends the storage address of the thumbnail to the presentation layer. The presentation layer presents the drawn thumbnail on the display, at which point the presentation interface of the display may refer to interface 34 in fig. 17.
