摘要： A modulation clock supplied to a drive circuit (7) of a display panel (1) is frequency-modulated so as to spread its harmonics spectrum. The frequency deviation is so restricted that, if at least two pixels corresponding to two adjacent scanning wirings are displayed based on arbitrary same luminance data, a difference in display luminance in a specified period between one pixel and the other pixel is less than or equal to a tolerable value determined by the luminance data. Consequently, reduction in unnecessary radiation can be achieved at a lower cost while suppressing deterioration in image quality

摘要： In an image display apparatus, image data on which gradation conversion for compensating phosphor saturation has been carried out by a gradation convertor (200) undergoes voltage drop compensation and then amplitude regulation using a gain (Gd) before being fed to modulating means (8). Here, the gradation convertor (200) changes its conversion characteristic (the region of a compensation table it uses) in accordance with the value of the gain (Gd). As a result it is possible to compensate the affects of phosphor saturation characteristics and voltage drop and an excellent image can be displayed.
