摘要： The stereoscopic image display includes a control voltage generator and a control voltage compensator. The control voltage generator generates a discharge control voltage to be applied to a discharge control line at a slight-on level, which is higher than a gate low voltage and is lower than a gate high voltage, and periodically reduces the discharge control voltage to a level of the gate low voltage in the 3D mode. The control voltage compensator receives the discharge control voltage from the control voltage generator, amplifies a feedback discharge control voltage supplied from a first part of a display panel based on the received discharge control voltage, and applies the amplified feedback discharge control voltage, as a compensated discharge control voltage, to a second part opposite the first part of the display panel.
