Abstract

The invention provides a display device. A display apparatus includes a display, a controller configured to read a rotatable direction of the display in response to a control instruction input by a user, and control the display to rotate to a preset angle in the rotatable direction. Based on the invention, the controller reads the rotatable direction of the display device before controlling the display to rotate each time, the rotatable angle in the rotatable direction is larger than the preset angle, and the display is controlled to rotate to the preset angle in the rotatable direction, so that the damage of the display caused by excessive rotation can be avoided by the control mode.

Description

Display apparatus The application is a divisional application (application number: 202010177064.4, application date: 2020-03-13, application name: display device). Technical Field The disclosure relates to the technical field of smart televisions, and in particular relates to a display device. Background The intelligent television equipment is provided with an independent operating system and supports function expansion. Various application programs, such as a traditional video application, a social application such as a short video and the like, and a reading application such as a cartoon and a reading application such as a reading application, can be installed in the intelligent television according to user needs. The applications can utilize the screen of the intelligent television to display application pictures, and rich media resources are provided for the intelligent television. Meanwhile, the intelligent television can also perform data interaction and resource sharing with different terminals. For example, the smart tv may be connected to the mobile phone through a wireless communication manner such as a local area network, bluetooth, etc., so as to play resources in the mobile phone or directly perform screen projection to display a picture on the mobile phone. However, since the proportion of pictures corresponding to different applications or media of different sources is different, smart televisions are often used to display pictures with a proportion different from that of conventional video. For example, video assets taken through terminals such as cell phones are typically vertical assets with aspect ratios of 9:16, 9:18, 3:4, etc., while pictures provided by reading applications are vertical assets similar to book aspect ratios. The aspect ratio of the display screen of the intelligent television is generally in a horizontal state of 16:9 and the like, so that when the intelligent television displays vertical media assets such as short videos and cartoon, the vertical media asset images cannot be normally displayed due to mismatching of the image proportion and the display screen proportion. The vertical media frames are generally required to be scaled to be displayed completely, which not only wastes the display space on the screen, but also brings bad user experience.
