Image display device and method supporting interactive display with intelligent terminal

The invention discloses an image display device and method supporting interactive display with an intelligent terminal. According to the image display device supporting the interactive display with the intelligent terminal, a signal input module is used for preprocessing wired or wireless signals output by the intelligent terminal and converting the signals into digital RGB (red, green and blue) signals; an image processing module is used for zooming and rotating the digital RGB signals; a display driving module is used for converting image signals output by the image processing module into signals that a display screen can receive; a touch sensing module is used for recognizing the track of the touch operations of a user on a touch screen and converting the track of the touch operations into operating signals for the intelligent signals to achieve interactive control on the intelligent terminal. The image display device supporting the interactive display with the intelligent terminal can perform treatments such as rotation and zooming on an input signal source and accordingly can achieve full-screen synchronous display of the screen content on a display device no matter whether the intelligent terminal is horizontally arranged or vertically arranged; through operations on the large touch screen of the display device, interactive operation and control on the intelligent terminal can be achieved, so that user experience can be enhanced.
