Abstract

PURPOSE: To reduce crosstalk by adding input display dot data, column by column, obtaining brightness correction data on each column according to final addition data, and adding this brightness correction data to the input display dot data.
CONSTITUTION: An arithmetic means 22 adds the input display dot data DATA to data read out of a storage means 23 and stores the new addition data in the storage means 23 again, and this operation is repeated as to all lines in a display period to store the sum of DATA in respective columns. An arithmetic means 24 converts the sum of DATA in the respective columns into the brightness correction data, which is stored in the storage means 25 and the data is read out simultaneously with the start of the display period to add the brightness correction data to the DATA by an arithmetic means 26. Namely, the gradation of white is increased, column by column, according to the sum of excessive voltages applied to the respective columns to correct a difference in brightness. Consequently, the crosstalk is reduced.
