In response to the confirmation operation of the history window, the controller is configured to execute S53 to control the display to continue to show the file corresponding to the history window with the playing progress recorded by the history window as a starting point.

The confirmation operation of the user on the history window may be, but is not limited to, when the user controls the cursor to move to the history window through the remote controller, the user touches a confirmation key of the remote controller.

The display device at least comprises a display and a controller, wherein the display displays a first interface under the condition of being connected with an external memory, the first interface at least comprises a first area, the first area is used for displaying a history window for storing file playing progress in the external memory, and each history window corresponds to one file; and responding to the confirmation operation of the history window, and continuing to display the file corresponding to the history window by taking the playing progress recorded by the history window as a starting point. The user does not need to manually adjust the playing progress, and the user experience is good.

A second aspect of the embodiment of the present application shows a file displaying method, including:

The method for displaying the file is suitable for display equipment, the display equipment at least comprises a controller and a display, and under the condition of being connected with an external memory, the display displays a first interface, the first interface at least comprises a first area, the first area is used for displaying a history window for storing file playing progress in the external memory, and each history window corresponds to one file; and responding to the confirmation operation of the history window, and continuing to display the file corresponding to the history window by taking the playing progress recorded by the history window as a starting point. The user does not need to manually adjust the playing progress, and the user experience is good.

Most of the current display devices support media center file playing, and can play media files in various types of memories including a flash disk, a mobile hard disk and the like. And the display device supports users to create play lists according to self requirements, so that customized play of the media video files is realized. However, for a video file with longer content, after a user creates a play list or opens a video in a certain video folder to start playing the video, if the user needs to view the play list or the video under the current folder, the user needs to view the video through a shortcut menu play list, at this time, the user can only see the name of the video, but cannot see the thumbnail of the video, and the call of the shortcut menu can form partial shielding for the video being played, so that the user experience is poor.

For example: fig. 28 is a schematic diagram of a video playback interface in memory. When the user opens the video in the play memory, an interface as shown in fig. 28 is displayed. When the user wants to view the playlist, the "shortcut menu key" on the control device may be pressed, and the display apparatus calls up the menu interface 61 at the current video playback interface in response to the user's operation, as shown in fig. 29. Included in menu interface 61 are repetition control 611, display history control 612, information control 613, playlist control 614, screen-off control 615, picture control 616, and sound control 617, and menu interface 61 also includes focus 62 for indicating any control is selected. The user moves the position of the focus 62 in the menu box by pressing the "up" and "down" keys on the control device to change the control selected by the focus 62. The inter-user focus 62 moves to the position of the playlist control 614 and after the playlist control 614 is selected, the "ok key" of the control device is pressed to enter the playlist submenu interface. FIG. 30 is a schematic diagram of a playlist submenu interface. As shown in fig. 30, names of all video files are displayed in a playlist, a currently played video file is selected by a focus, and a user can change a position of the focus on a sub-menu of the playlist through an up-down button of the control device to select a different video file control. After the selected video file, the video file can be played after the 'confirm key' of the control device is pressed.

It should be noted that controls, which are visual objects displayed in the display areas of the user interface in the display device 200 to represent corresponding contents such as icons, thumbnails, video clips, links, etc., can provide the user with various conventional program contents received through data broadcasting, and various application and service contents set by the content manufacturer.

The presentation form of the control is typically diversified. For example, the controls may include text content and/or images for displaying thumbnails related to the text content, or video clips related to the text. As another example, the control may be text and/or an icon of an application.

It should also be noted that the focus is used to indicate that any of the controls has been selected, such as the focus object. In one aspect, the control may be selected or controlled by controlling movement of the display focus object in the display device 200 according to user input through the control apparatus 100. Such as: the user may select and control controls by directional keying movement of the control focus object between controls on the control device 100. On the other hand, the movement of each control displayed in the display apparatus 200 may be controlled to cause the focus object to select or control the control according to the input of the user through the control device 100. Such as: the user can control the controls to move left and right together through the direction keys on the control device 100, so that the focus object can select and control the controls while the position of the focus object is kept unchanged.

The form of identification of the focal point is typically varied. By way of example, the location of the focus object is achieved or identified by magnifying the control, by setting the control background color, or by changing the border line, size, color, transparency, outline, and/or font of the text or image of the focus control.

From the above operations, it can be seen that the steps of opening the playlist by the user are complicated, and only the names of the video files in the playlist cannot help the user to find the desired files more accurately. Meanwhile, the play list is called out through the shortcut menu, and the bottom color of the menu interface is opaque, so that the current video playing picture is often shielded. In addition, if the user does not actively exit the playlist, i.e., the user does not press the "back key" of the control device, the shortcut menu interface and the playlist submenu interface will always block the video picture being played, and the user experience is poor.

In order to solve the above technical problems, embodiments of the present application provide a display device, and the structure and functions of each portion of the display device may refer to the above embodiments. In addition, on the basis of the display device shown in the foregoing embodiments, some functions of the display device are further optimized in this embodiment, and specifically, reference may be made to fig. 31, where fig. 31 is a flowchart of interaction between the display device and a user according to some embodiments;
