Abstract

The invention discloses a method for achieving 3D (three-dimensional) image display and a liquid crystal display television. The method is applied to the liquid crystal display television. The method comprises the steps: receiving a 3D enable signal and a field-synchronizing signal when the signal to be displayed is a 3D signal, obtaining N paths of backlight modulation signals and a 3D eyeglasses synchronizing signal based on the 3D enable signal and the field-synchronizing signal, wherein N is an integer being more than or equal to 2, opening a left spectacle lens based on the 3D eyeglasses synchronizing signal, and modulating N block light sources corresponding to N backlight blocks through the N paths of backlight modulation signals, so that the block light sources corresponding to a left eyeglass and a left eye image are synchronized, and the left eye image is displayed on a 3D liquid crystal panel; and opening a right spectacle lens based on the 3D eyeglasses synchronizing signal, and modulating the N block light sources through the N paths of backlight modulation signals, so that the block light sources corresponding to a right eyeglass and a right eye image are synchronized, and the right eye image is displayed on the 3D liquid crystal panel.

Description

technical field [0001] The invention relates to the field of smart televisions, in particular to a method for realizing 3D image display and a liquid crystal television. Background technique [0002] 3D image display technology is a technology that uses a series of optical methods to make people's left and right eyes produce parallax to receive different pictures and form a 3D stereoscopic effect in the brain. [0003] Human eyes can look in the same direction at the same time, but the distance between the eyes is still 65mm, so they cannot completely aim at a straight line. Within a certain range, the images seen by both eyes will have certain differences, that is, the human eyes have a three-dimensional feeling when observing the scene. The main reason is that the two eyes observe the scene from different angles. The left eye sees more of the left side of the object, and the right eye sees more of the right side of the object. The images formed on the left and right retina...
