Abstract
Provided is a stereoscopic image display device comprising a display panel displaying a multi-view image in a three-dimensional (3D) mode, a switchable barrier forming a barrier in the 3D mode, a user position detecting unit outputting a user position data including a user position information, a switchable barrier controlling unit calculating an average picture level of the multi-view image in the 3D mode and controlling an aperture ratio of the switchable barrier according to the average picture level and the user position information, a switchable barrier driving unit supplying driving voltages to divided electrodes of the switchable barrier and supplying a common voltage to a barrier common electrode, and a display panel driving unit converting the multi-view image into data voltages to supply the data voltages to data lines of the display panel and sequentially supplying gate pulses to gate lines of the display panel.
