Embodiment Construction

[0009] The present invention will be further described below in combination with specific embodiments and accompanying drawings.

[0010] Such as figure 1 The flow chart of the method for eliminating ghosting in polarized 3D LCD TVs is shown, which specifically includes the following steps: firstly, it is detected whether the system is currently working in 2D state or 3D state; Complete 3D image decoding; if the system is currently working in 2D state, the system immediately turns on overscan and calls 2D parameters to complete 2D image decoding. The working state of the system is determined by the user's remote operation of the 3D menu. When the user selects the 3D format, the system starts to work in 3D state, and after exiting 3D, the system works in 2D state. From the above process, we can see that the overscan function used in the 2D state lifts the original 2D image and cuts the edge, so that a circle around the screen is cut off to cover the distortion of the edge of t...

Abstract

The invention relates to the field of televisions, and discloses a ghost cancellation method of a polarized light three-dimensional (3D) liquid crystal display television (LCD TV). The ghost cancellation method of the polarized light 3D LCD TV concretely includes the following steps: first detecting whether a system works in a two-dimensional (2D) state or in a 3D state currently, if the system works in the 3D state currently, shutting down overscanning immediately, and invoking 3D parameters to complete 3D picture decoding; and if the system works in the 2D state, the system starting the overscanning immediately, and invoking 2D parameters to complete 2D picture decoding. The overscanning function is shut down in the 3D state to maintain the original ratio of the 3D image, the 3D image can be displayed on the polarized light LCD accurately, therefore ghost is effectively cancelled, and a user can watch vivid 3D videos on a Ypbpr channel and a video graphics array (VGA) channel.

Description

technical field [0001] The invention relates to the field of televisions, in particular to a ghost elimination method for polarized 3D liquid crystal televisions. Background technique [0002] 3D is the abbreviation of three-dimensional, that is, three-dimensional graphics. Since the angles of observing objects with the human eyes are slightly different, it is possible to distinguish the distance of objects and produce stereoscopic vision. Three-dimensional stereoscopic video TV uses this principle to separate the images seen by the left and right eyes. The three-dimensional display effect of 3D LCD TV is to send the coded 3D video images to the left and right eyes independently by adding a special precision cylindrical lens screen on the LCD panel. Among them, polarized 3D technology is also called polarized 3D technology, which is Polarization 3D in English, and passive polarized glasses are used in conjunction with it. The image effect of polarized 3D technology is bet...
