A local area image displaying system is provided for a screen of a display device for controlling a displaying area of the display device. The system includes a pixel matrix, a data driving circuit, a gate driving circuit, a timing controller, and a microprocessor unit. The pixel matrix includes plural pixel units that are arranged in a matrix form to define a global displaying area. The timing controller controls the operation timings of the data driving circuit and the gate driving circuit to selectively and respectively supply a data voltage and a gate voltage to at least one selected pixel unit. The timing controller bases on a local displaying area in which displaying is to be performed to control the data lines and the gate lines covering the local displaying area to supply the voltages so as to enable only the pixel units contained in the local displaying area.
