Display device, and method for driving display device

摘要

In order to provide a display device and a method for driving a display device, each of which is capable of repairing a disconnection in a data signal line and further reduces electric power consumption, a display device (1) includes a repair amplifier control section (14) for causing a repair amplifier circuit (12) to operate at a low-performance level during any period within a period from when scanning of pixels in the display area in the display device (1) is finished to when next scanning is started.

主权项

1. A display device comprising:
a data signal line configured to supply, to a display area, a signal necessary for display; a first wire connectable to the data signal line, the first wire being provided on a first side of the display area, the data signal line receives the signal on the first side of the display area; a second wire connectable to the data signal line, the second wire being provided on a second side of the display area which is opposite to the first side; an amplifier circuit which includes an input terminal connected to the first wire and an output terminal connected to the second wire; a performance controller configured or programmed to cause the amplifier circuit to be in a low-performance state during any period within a period from when scanning of pixels in the display area is finished to when next scanning is started; a data signal generating circuit configured to generate the signal and to supply the signal (i) to the data signal line and (ii) to the amplifier circuit via the first wire which is connectable to the data signal line; and a data signal generation ability controller configured or programmed to cause the data signal generating circuit to be in a low-performance state during any period within the period from when the scanning is finished to when the next scanning is started; wherein the data signal generation ability controller is configured or programmed to cause the low-performance state of the data signal generating circuit to end before the scanning is started; and the performance controller is configured or programmed to cause the low-performance state of the amplifier circuit to end before the data signal generation ability controller causes the low-performance state of the data signal generating circuit to end.
