发明名称 DISPLAY DEVICE
摘要 In an image display device, each pixel includes a drive transistor for driving a light emitting element, a capacitive element which is connected between a signal line and a control electrode of the drive transistor, and a reset switching element. The reset switching elements of all pixels are turned off within a light emission period, and a PWM signal is supplied to a signal line from a drive circuit. A cycle of the PWM signal in a low brightness display mode is shorter than a cycle of the PWM signal in a standard brightness display mode. Due to such a constitution, the constitution of a drive circuit can be simplified, and it is possible to control light emission brightnesses of respective pixels of red, green and blue over a wide range from high brightness to low brightness while taking a balance among the light emission brightnesses.
