Description

Display device and method of operating the same Technical Field The present disclosure relates to a display device. Background Recently, functions of terminals are being diversified. For example, there are functions of data and voice communication, taking photos and videos through a camera, recording sound, playing back music files through a speaker system, and outputting images or videos to a display. Some terminals add an electronic game function or perform a multimedia play function. As the functions of the terminal are diversified, the terminal is implemented, for example, in the form of a multimedia device (multimedia player) equipped with complex functions such as photographing still pictures or moving pictures, reproducing music or video files, playing games, receiving broadcasting, and the like. When the display size of the terminal is greater than a certain inch (e.g., 27 inches), it is difficult for the user to touch the display. That is, in a display device having a size larger than a certain size, more finger movements are required to perform the same operation as a touch operation of a display device having the same size as a conventional tablet, which causes inconvenience to a user. Disclosure of Invention The present disclosure provides a display apparatus that optimizes usability by changing display properties according to the type of user input to the display apparatus. The present disclosure provides a display device that optimizes use of touches. According to an embodiment of the present disclosure, a display apparatus may include a display configured to display an image, a user input interface configured to receive a remote control input from the remote control, and a controller configured to receive a user input, obtain a type of the received user input, and change a display property according to the obtained type of the user input, wherein the type of the user input is one of a remote control input type or a touch input. According to the embodiments of the present disclosure, a GUI of an appropriate size may be provided according to the type of user input, thus greatly improving convenience of input. According to the embodiments of the present disclosure, the screen is reduced with respect to the point of the touch input, thus optimizing the use of the user's touch. According to the embodiments of the present disclosure, glare may be prevented by adjusting the output brightness of an image according to the type of user input in case of touch input control by a user. According to the embodiments of the present disclosure, the size of an image is reduced according to a touch input, thereby preventing a user from feeling inconvenienced while viewing the image.
