Patent ID: 8791912

Claim:
A display system comprising: a plurality of electrical apparatuses, wherein each of the electrical apparatuses comprises a display unit, wherein each of the display units is a touch screen; and a display control unit building connections with the electrical apparatuses, wherein the display control unit comprises: an information generating module for detecting and generating combination information about combination relations among the display units of the electrical apparatuses when the display system is in a combination display mode; a display driving module for driving each of the display units to display a corresponding image block according to the combination information, such that the displayed corresponding image blocks are combined to form an entire image; a touched-position receiving module for receiving detection signals from the display units and generating corresponding touch gesture signals which include times, at which the touch gestures were made, when the display system is in the combination display mode, wherein when the display system is in the combination display mode and one of the display units is touched, the touched-position receiving module receives an actually touched position of the touched display unit; and a position calculating module for calculating a touched position in relation to the entire image according to the information of the touched display unit, the combination information and the actually touched position; wherein the information generating module uses the touch gesture signals to generate the combination information by determining that touch gestures, which are made on two of the display units at times close to each other, are neighboring to each other.
