DISPLAY UNIT AND ELECTRONIC BLACKBOARD SYSTEM USING THE SAME

摘要

PURPOSE: A display device and an electronic blackboard system using the same are provided to implement simply design by inputting a control signal of the display device through a touch area. CONSTITUTION: A touch input module includes a first coordinate signal processing unit(125) and a second coordinate signal processing unit(127) within a display area of a touch screen. A touch module processing unit(210) receives first and second contact location signals of first and second coordinate signal processing units. An image signal generating unit(220) generates the image signal according to the first contact location signal. A control signal generating unit(230) generates the control signal according to the second contact location signal.
