Abstract: A stereoscopic image display includes a display panel; a polarization control panel that is positioned on the display panel and controls the polarization direction of light incident from the display panel; a lens panel positioned on the polarization control panel and having a plurality of lens shaping portions; a first driver for driving the display panel; a second driver for supplying a driving voltage to the polarization control panel; a timing controller for controlling the first driver and the second driver; and a sensing unit that senses the driving voltage supplied to the polarization control panel and outputs a decision signal for deciding whether the sensed driving voltage is in normal condition or abnormal condition.

Abstract: 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.
