Description

Display device and operation method thereof Technical Field The present invention relates to a display device and an operation method thereof, and more particularly, to a stand-type display device and an operation method thereof. Background With the development of the information society, the demand for display devices has increased in various forms, and for this purpose, various display devices such as LCD (Liquid CRYSTAL DISPLAY DEVICE: liquid crystal display device), PDP (PLASMA DISPLAY PANEL: plasma display panel), ELD (Electro luminescent Display: electroluminescent display), VFD (Vacuum Fluorescent Display: vacuum fluorescent display), OLED (Organic LIGHT EMITTING Diode) and the like have been studied in recent years. The LCD panel may have a TFT (Thin Film Transistor: thin film transistor) substrate and a color substrate opposite to each other across a liquid crystal layer, and may display an image using light supplied from a backlight unit. The OLED panel may display an image by depositing an organic layer capable of self-luminescence on a substrate formed with a transparent electrode. Recently, many studies have been made on a structure of a display device in which a stand is detachably provided to a head portion having a display function. The user may mount the bracket to the head and view the image in the form of a bracket type, or separate the bracket from the head and view the image through the head. In the case where the user views an image through the head after separating the bracket, a protective Cover (Folio Cover) covering the head may be used. In the case where the display panel provided to the head is covered by the protective cover, the picture of the head may be closed by the magnetic field sensed by the hall sensor. However, the existing display device does not have a function of detecting whether or not the stand and the head are separated. In this case, there is a problem in that when a user mounts a bracket to a head and attaches a remote controller having a magnet to a position where a hall sensor of the head is located, a picture of the head is closed by a magnetic field sensed by the hall sensor. In addition, in the case of using the display device in a cradle form and the case of using only the head as the display device, sound quality settings or image quality settings may be different from each other. In this case, there is a problem in that a user needs to manually operate a set value through a set menu in a case of using the display device in a cradle form and then separating the cradle and using the display device in a head type. Disclosure of Invention The present invention aims to prevent a hall sensor provided to a head from being unnecessarily activated. The object of the invention is to deactivate the function of a Hall sensor in the case of using a display device in the form of a stand without a protective cover. The present invention aims to actuate a display device by sensing separation or installation between a stand and a head in a setting matching a sensed condition. The display device of an embodiment of the present invention may include a head having a display and a sensor for opening or closing a picture of the display and a controller that may sense whether a bracket supporting the head is fastened to the head, and may deactivate a function of the sensor in case that the bracket is sensed to be fastened to the head. In the method of operating the display device of an embodiment of the present invention, the display device may include a head having a display and a sensor and a controller for opening or closing a picture of the display, the method of operating may include a step of sensing whether a bracket supporting the head is fastened to the head, and a step of disabling a function of the sensor if it is sensed that the bracket is fastened to the head. According to an embodiment of the present invention, the function of the hall sensor may be deactivated in case of fastening of the bracket and the head. Thus, even if the user places the remote control device adjacent to the magnet located inside the head, the problem of the screen closing of the display can be solved. According to the embodiment of the invention, a plurality of setting values of the display device can be automatically optimized according to whether the bracket and the head are fastened or not. Thus, the user does not need to perform a separate manual operation, and the convenience of use of the display device can be greatly improved.
