Publication number: 20090046214Abstract: A 2D/3D convertible display apparatus and a method of driving the same are provided. The 2D/3D convertible display apparatus includes a liquid crystal display panel, a polarizing panel changing the direction of polarization of an incident light beam according to a signal applied thereto, a panel driver applying a driving signal to the liquid crystal display panel when receiving a vertical synchronization signal and applying a driving signal to the polarizing panel when receiving a stereo synchronization signal, and a synchronization signal generator generating the stereo synchronization signal to allow the panel driver to apply the driving signal to the polarizing panel in both 2D and 3D modes. Accordingly, the driving signal is applied to the polarizing panel in the 2D mode to solve a problem that the polarizing panel is off to cause a defective image to be displayed when the driving signal is not applied to the polarizing panel in the 2D mode.Type: ApplicationFiled: June 2, 2008Publication date: February 19, 2009Applicant: SAMSUNG ELECTRONICS CO., LTD.Inventors: Sang-moo PARK, Sergey CHESTAK, Dae-sik KIM, Jae-phil KOO
