The invention relates to a display device, and discloses a 3D display device and its driving method and device. The display device comprises a pixel array and a raster, the pixel array comprises multiple columns of sub-pixel groups, each column of sub-pixel groups comprises M*N sub-pixels, wherein M is the number of color categories, and N is a positive integer greater than 3; each sub-pixel has a rectangular shape, and the odd columns of sub-pixel groups and the even columns of sub-pixel groups are set staggerly; the display device comprises multiple occluding rectangles arranged in a regular array, wherein occluding rectangles in neighboring columns are set staggerly in the column direction, and occluding rectangles in columns separated by a column are symmetrically set relative to the column between them in the row direction.

An embodiment of the present invention provides a three-dimensional (3D) display device. The 3D display device comprises: a display panel, configured to display an image and comprising a plurality of pixels; and a 3D grating, disposed at a light-emitting side of the display panel and comprising an electrochromic layer, wherein the electrochromic layer comprises a plurality of electrochromic strip bodies spaced apart from each other with an equal interval, and when a voltage is applied to each of the plurality of electrochromic strip bodies, a change between a light-shielding state and a light-transmitting state is achieved.

Three-dimensional (3D) electronic displays provide different 3D views and employ one or both of an array of multibeam diffraction gratings arranged in offset rows and light valves having color filters. The displays include a plate light guide configured to guide light beams at a non-zero propagation angle, a multibeam diffraction grating configured to couple out a portion of the guided light beams as a plurality of light beams having different principal angular directions representing the different 3D views, and light valves configured to modulate the differently directed, coupled-out light beams. The multibeam diffraction grating may be a member of the array arranged in offset rows and the display may further include light valves having color filters. Alternately, the light valves include color filters and the display may further include the array of multibeam diffraction gratings arranged in offset rows.

An image display device includes a display panel, a barrier panel, and a controller. In the controller, first display regions and second display regions can be set in the display panel. First transparent regions and second transparent regions can be set in the barrier panel. Eye-position information of a user can be acquired. Based on the eye-position information, a reference position can be set. Based on a distance from the reference position, division regions can be set for at least one of the display panel and the barrier panel. At least one of the parallax image pitch representing a pitch at which the first display regions and the second display regions are alternately arranged and the barrier pitch representing a pitch at which the first transparent regions and the second transparent regions are alternately arranged can be set for each of the division regions.

A method of displaying a three-dimensional (“3D”) image, the method includes determining a shutter electrode of an unit part included in a shutter panel as a left-eye electrode and a right-eye electrode, the unit part including ‘n’ shutter electrodes (herein, n is a natural number), selectively driving the left-eye electrode and the right-eye electrode as an opening part based on an image displayed on a display panel to transmit light through the opening part, and providing light transmitted through the opening part with an observer's two eyes through a lens plate, the lens plate including a plurality of lenses.
