Abstract:
1. A display device comprising: a display panel having a plurality of display pixels and a video line inputting video data to the display pixels; the display pixels each having a memory unit storing the video data; the memory unit including a first inverter circuit, whose input terminal is connected to a first node and whose output terminal is connected to a second node, and a second inverter circuit, whose input terminal is connected to the second node and whose output terminal is connected to the first node; wherein the display pixel has a first transistor, directly connected between the output terminal of the second inverter circuit and the video line, and a second transistor, directly connected between the first node and the video line; wherein when the video data is read from the memory unit the first transistor is turned ON and the second transistor is turned OFF in order to output the video data stored in the memory unit to the video line; and wherein when the video data is written into the memory unit the first transistor is turned OFF and the second transistor is turned ON in order to input the video data supplied to the video line to the first node.
