摘要： A correction circuit includes a timing control circuit for dividing a drive period assigned for drive of display devices into plural calculation slots, a luminance calculation circuit for calculating luminance including an effect of a voltage drop for each calculation slot, an accumulation circuit for temporally accumulating the luminance for each calculation slot, a corrected data determination circuit for outputting, as a corrected data, the value determined in accordance with the calculation slot at the time point when the accumulated luminance reaches a target luminance value, and a conversion circuit for converting the corrected data into modulation data to be applied to a modulation circuit. The width of the calculation slot is shorter than the width of the slot for pulse width modulation in at least a part of the drive period. The conversion circuit reduces the bit width of the corrected data by pseudo-gradation processing.

摘要： An image display apparatus includes: a display panel; a calculation circuit that calculates a luminance control value, which is a parameter for controlling display luminance, for each frame of a video signal to be displayed on the display panel; and a luminance control circuit that controls the display luminance of the frame using the luminance control value calculated by the calculation circuit. When the video signal is a video signal in which one image is constituted by a plurality of frames, the luminance control circuit applies a same luminance control value to the plurality of frames constituting one image, or decreases the difference of the luminance control values applied to the plurality of frames constituting one image to be lower than a predetermined value.

摘要： An image display apparatus is driven by a driving method including, based on a horizontal synchronizing signal, stopping an output of a modulation signal at a first timing regardless of the state of the modulation signal, shifting a row wiring, to which a selection signal is output, at a second timing, and starting the output of the modulation signal at a third timing. The first timing is performed before the second timing, whereby the image display apparatus can be stably driven against a wrong horizontal synchronizing signal.

摘要： 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.
