An optical receiver 233 receives an optical signal (including a control signal) from an external control device through an optical window (not shown) on a bezel of the display 220. The optical receiver 233 may receive an optical signal corresponding to a user input (e.g., a touch, a push, a touch gesture, a voice, or a motion) from the external control device. The control signal may be extracted from the received optical signal under control of the controller 210.
The I/O interface 270 receives video (e.g., a moving picture), audio (e.g., a voice or music), and additional information (e.g., an EPG), and the like from the outside of the image display apparatus under control of the controller 210. The I/O interface 270 may include one of a high definition multimedia interface (HDMI) port 271, a component jack 272, a PC port 273, and a universal serial bus (USB) port 274. The I/O interface 270 may include a combination of the HDMI port 271, the component jack 272, the PC port 273, and the USB port 274, according to an exemplary embodiment.
It will be easily understood by those of ordinary skill in the art that a configuration and operation of the I/O interface 270 may be implemented in various way according to exemplary embodiments.
The controller 210 controls the general operation of the image display apparatus and a signal flow between the internal components 210 to 290 of the image display apparatus and processes data. If an input of the user exists, or a previously set and stored condition is satisfied, the controller 210 may execute an operating system (OS) and various applications stored in the storage 290.
