A method of controlling a display device is provided. The method includes the steps of receiving an input data; decoding a stored image to obtain decoded data; accumulating the decoded data to obtain an accumulated value; adding the accumulated value to the input data to obtain a compared value; setting the display device to operate normally when the compared value is identical to an initial value; and displaying a preset frame on the display device when the compared value is different from the initial value.
