Abstract

Data of display data signals input to a plurality of display circuits are alternately switched between an image data for the left eye and an image data for the right eye every a plurality of frame periods; the plurality of display circuits are divided into a plurality of groups each including the display circuits in at least one row, and in each group, pulses of display selection signals are sequentially input Z (Z is a natural number greater than or equal to 3) times to the display circuits in the respective rows; and data of the display data signal input during a K-th (K is a natural number greater than or equal to 2) frame period and data of the display data signal input during a (K-1)-th frame period are compared. As a result, a color image and a black image are selectively displayed.

Description

technical field [0001] Embodiments of the present invention relate to a method of driving a liquid crystal display device. Background technique [0002] In recent years, research and development has been conducted on liquid crystal display devices capable of displaying pseudo 3D images. [0003] Examples of the aforementioned liquid crystal display device capable of displaying a pseudo-3D image include a liquid crystal display device that causes a viewer to view a two-dimensional (2D) image as a 3D image using parallax between left and right eyes. In the above example of the liquid crystal display device, an image for the left eye (hereinafter also referred to as left-eye image) and an image for the right eye (hereinafter also referred to as right-eye image) are alternately displayed on the pixel portion, and the viewer The above images are viewed using glasses equipped with polarization shutters including liquid crystals for the left and right eyes. When the image for the...
