Abstract:
1. An image display device including luminescence pixels arranged in rows and columns, the image display device comprising: a first power source line and a second power source line; a first signal line and a second signal line for supplying the luminescence pixels with a signal voltage that determines luminance of the luminescence pixels; a signal line driver that outputs the signal voltage to the first signal line and the second signal line; a timing controller that controls a timing at which the signal line driver outputs the signal voltage; scanning lines, each for one of the rows; and first control lines, wherein the luminescence pixels compose at least two drive blocks, each including luminescence pixels in at least two of the rows, each of the luminescence pixels includes: the current controller includes: each of the luminescence pixels in a k each of the luminescence pixels that belong to a (k+1) each of the first control lines is connected to the luminescence pixels in a same one of the drive blocks and not connected to the luminescence pixels in different ones of the drive blocks, k is a positive integer, a threshold voltage correction period of the (k+1) the signal voltage includes a luminance signal voltage for causing the luminescence element to produce the luminescence, and a reference voltage for causing the first capacitor to store a voltage corresponding to a threshold voltage of the drive transistor, and the timing controller is configured to mutually and exclusively output the luminance final voltage and the reference voltage to the first signal line and the second signal line.
