Abstract:
1. An electrophoresis display device comprising: a display panel including data lines and gate lines that intersect the data lines; a data driving circuit including a data output channel, the data driving circuit converting digital data into data voltages that are outputted to the data lines via the data output channel during an image update period; a gate driving circuit comprising an output channel, the gate driving circuit outputting gate signals to the gate lines via the output channel during the image update period; and a gate discharge transistor connected to the output channel of the gate driving circuit and an intersection of a gate line and a data line, the gate discharge transistor providing a pathway that continuously discharges the output channel of the gate driving circuit during a stabilization period subsequent the image update period in response to a power consumption shutoff control signal, wherein the gate driving circuit outputs a gate signal that alternates between a first gate level and a second gate level that is greater than the first gate level during the image update period, wherein during the image update period the power consumption shutoff control signal is output at a first signal level responsive to the second gate level of any gate signal and output at a second signal level different from the first signal level of the power consumption shutoff control signal responsive to a transition to the first gate level of any gate signal, and wherein the gate discharge transistor provides a pathway to discharge the output channel of the gate driving circuit during the image update period responsive to the second signal level of the power consumption shutoff control signal during the image update period, and the gate signal is output to the gate line via the output channel during the image update period responsive to the first signal level of the power consumption shutoff control signal during the image update period.
