Abstract

The invention discloses a backlight module, a 3D display device and a driving method thereof. The employed backlight module comprises a backlight source and a control portion, wherein the backlight source has multiple light emitting regions in one-to-one correspondence with sub pixels of a liquid crystal display screen, and the light emission directions of the light emitting regions of the backlight source can be controlled by the control portion. The backlight module can provide the directional light source for the sub pixels, so left and right eyes can respectively see two stereo pairs of corresponding images by time division, and the images are comprehensively processed by the brain to achieve multi-view naked-eye 3D image display without loss of resolution.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a backlight module, a 3D display device and a driving method thereof. Background technique [0002] At present, three-dimensional (Three-Dimensional, 3D) display technology has attracted much attention. It can make the picture three-dimensional and realistic. Superimposed and regenerated to form images with stereoscopic effects. [0003] Currently, there are two types of 3D display technologies: glasses-free and glasses-based. The so-called naked-eye type is to send encoded 3D video images to the left and right eyes independently through special processing on the display panel, so that users can experience the stereoscopic feeling with naked eyes without the help of stereoscopic glasses. [0004] At present, the naked-eye 3D display is realized mainly by setting barriers such as grating barriers (Barrier) or liquid crystal lenses in front of the light source array of liquid cr...
