摘要： PURPOSE: A device for displaying an LCD of a mobile communication terminal is provided to distinguish levels of R, G, and B input signals inputted on an LCD, and to apply different compensation values according to each level, thereby more precisely improving picture quality of the LCD. CONSTITUTION: Red compensation resisters(RAD1-RADn) store each compensation value of levels of a red input signal. Green compensation resisters(GAD1-GADn) store compensation values of levels of a green input signal. Blue compensation resisters(BAD1-BADn) store compensation values of levels of a blue input signal. The first multiplexer(M1) selects one of the red compensation resisters(RAD1-RADn) according to the levels of the red input signal. The second multiplexer(M2) selects one of the green compensation resisters(GAD1-GADn) according to the levels of the green input signal. The third multiplexer(M3) selects one of the blue compensation resisters(BAD1-BADn) according to the levels of the blue input signal. The first adder(A1) adds a red compensation value of the first multiplexer(M1) to the red input signal. The second adder(A2) adds a green compensation value to the green input signal. The third adder(A3) adds a blue compensation value to the blue input signal.
