Patent ID: 8054275

Claim:
A liquid crystal driving circuit that (i) finds a corrected video signal by carrying out, with respect to each of video signals supplied from a signal source, a correction in which a temporal change in each of the video signals is enhanced, and (ii) causes a voltage which varies in accordance with the corrected video signal to reverse in polarity at every predetermined reference unit, and (iii) applies the voltage to a data signal line, said liquid crystal driving circuit, comprising: a memory for storing a table, the table storing, in accordance with combinations of values of the video signals, correction values, respectively, the correction values in which the temporal changes of the video signals are enhanced; and a correcting circuit for finding the corrected video signal by carrying out, with respect to a correction value selected from the table, a predetermined correcting operation in accordance with the polarity of the voltage, with the use of a correction coefficient which is set based on properties of liquid crystal, wherein the correcting circuit is configured to find a value of the corrected video signal by adding to, or subtracting from, a value of a video signal of the previous frame, a product of (i) the correction coefficient and (ii) a value found by subtracting the value of the video signal of a previous frame from the correction value.
