Abstract
The invention relates to a remote controlled positioning system, a control system and a display device thereof. The remote controlled positioning system includes a liquid crystal display (LCD) panel, a backlight source, a plurality of infrared ray (IR) sources and a directional remote controller. The LCD panel includes a plurality of display areas. The plurality of IR sources is disposed behind the LCD panel, wherein the IR sources are correspondingly disposed according to the positions of the display areas to respectively emit infrared rays to pass through the LCD panel. The directional remote control receives the infrared rays emitted by the infrared ray sources to obtain positional information pointed to a position of the LCD panel by the directional remote control.
