Display device operating in 2D and 3D display modes and method for driving the same

摘要

A display device includes a first scan line, a second scan line, a third scan line, a data line, a pixel, a low color-shifting circuit, and a black zone generation circuit. In the low color-shifting circuit, a low color-shifting switch receives a third scan signal from the third scan line to selectively couple a compensating capacitor to the second sub-pixel electrode. The black zone generation circuit receives a black zone generation signal to selectively couple either the first sub-pixel electrode or the second sub-pixel electrode to a common node such that either the first sub-pixel or the second sub-pixel becomes a black zone.
