Patent ID: 8736598

Claim:
An electrophoresis display apparatus comprising: a display panel comprising data lines and gate lines crossing the data lines; a data driving circuit generating data voltages selected among a positive voltage, a negative voltage, and a ground voltage during an image update period and supplying the data voltages to the data lines; a gate driving circuit supplying gate pulses to the gate lines in synchronization with the data voltages during an image update period; and a control logic circuit blocking an output of the data driving circuit when the positive voltage is lowered to less than a logic power voltage or when the logic power voltage is lowered to less than a preset internal voltage immediately after the image update period, wherein the positive voltage and the logic power voltage are direct current (DC) voltages, and wherein the logic power voltage is lower than the positive voltage and higher than the ground voltage and wherein the ground voltage is lower than the logic power voltage and higher than the negative voltage.
