Abstract: An apparatus and method thereof to improve a response speed of an LCD includes a noise rejection unit and a comparator. The noise rejection unit rejects noise in current digital image data and previous digital image data at a same pixel position as in the current digital image data. The comparator compares the current digital image data and the previous digital image data of which noises are rejected within a reference value, changes the current digital image data based on a comparison result, and outputs a result indicative thereof.
