Apparatus and method for improving response speed of LCD

摘要

An apparatus and method thereof to improve a response speed of an LCD includes a noise rejection unit (301,302) and a comparator (304). The noise rejection unit (301,302) 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 (304) 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.
