Patent ID: 8890948

Claim:
An image display device comprising: a display panel configured to selectively display a 2D image and a 3D image, the display panel including a subpixel disposed at a crossing between a pair of gate lines and a data line; a panel driver including a gate driver for driving the pair of gate lines and a data driver for driving the data line; a controller configured to differently control the panel driver in response to a mode selection signal; and a patterned retarder configured to divide light from the display panel into first polarized light and second polarized light, wherein in a 2D mode, an auxiliary display unit of the subpixel is charged to a common voltage in response to an auxiliary scan pulse supplied to an auxiliary gate line of the pair of gate lines, and then the auxiliary display unit and a main display unit of the subpixel are charged to a 2D data voltage for the 2D image by a main scan pulse supplied to a main gate line of the pair of gate lines, the main scan pulse being input later than the auxiliary scan pulse by a predetermined time period, and wherein in a 3D mode, the main display unit and the auxiliary display unit are charged to a 3D data voltage for the 3D image in response to the main scan pulse, and then the auxiliary display unit is charged to the common voltage by the auxiliary scan pulse, the auxiliary scan pulse being input later than the main scan pulse by the predetermined time period.
