Abstract
The effect of the fluctuation of a signal that is caused by interference between the lines of an image display apparatus can be reduced. For this purpose, an image display apparatus comprises a plurality of lines, a plurality of display devices to which signals are respectively transmitted along the lines, and a signal circuit for generating the signals. The signal circuit outputs a signal having a duration, which is equivalent to a high-level period, that has been corrected in accordance with the length of a high-level period for a signal that is to be transmitted to an adjacent line of each line or in accordance with the number of times the level of a signal that is to be transmitted to an adjacent line is changed during the high-level period, or in order to reduce a change in luminance due to a level change for a signal that is to be transmitted to an adjacent line. Preferably, to correct a luminance signal that is input to terminal d, a crosstalk correction unit employs for its own line luminance signals for adjacent lines.
