Abstract: The present disclosure relates to a remote control device, a method for driving a remote control device, an image display device, a method for driving an image display device, and a computer-readable recording medium. A remote control device according to the present disclosure may comprise: a processor for determining whether the remote control device is commanding a screen of an image display device; and a communication interface unit which, when the determined results show that the screen is being commanded, transmits, under the control of the processor, position information related to the commanded position to the image display device so that a point is displayed at the commanded position of the screen.

Abstract: A display apparatus is disclosed. The display apparatus includes a display, an input unit configured to receive a handwriting trace, in response to a user handwriting being performed at a remote control apparatus; a detector configured to determine text corresponding to the handwriting trace; and a controller configured to search for an item corresponding to the text, classify the item into a plurality of categories, and control the display to display the item on the display.

Abstract: An electronic apparatus, an input apparatus and a method of determining a remaining utility of a battery of the same, the electronic apparatus including: a battery configured to supply power to the electronic apparatus; a first detector configured to receive a voltage value of the battery, to convert the voltage value into a signal, and to output the signal; a second detector configured to detect a decrease in the voltage value of the battery to a reference voltage or lower and to output a detection result; and a controller configured to receive the output values of the first and second detectors, to determine a remaining utility of the battery based on the output values of the first and second detectors, and to determine an abnormal state of the battery based on the output values of the first and second detectors.

Abstract: Disclosed is a display apparatus which performs wireless communication with a target control device and a peripheral display apparatus. The display apparatus may include communication circuitry which transmits to the peripheral display apparatus a request message requesting a determination of whether an operation command of the target control device is received when the target control device is operated; and a controller configured to perform a function corresponding to the operation command of the target control device based on a response message to the request message. In the display apparatus and a control system and method for the same, the display apparatus is able to be controlled through a control device paired with a different display apparatus, and since a re-pairing process is not performed, an additional operation in which a user performs the re-pairing process may be removed, and thus user convenience may be improved.
