Method, TV set for displaying 3D image and glasses

A method for displaying a 3d video, comprising:

• receiving a 3d video signals, the 3d video signal comprising a frame of a left-eye signal and a frame of a right-eye signal;
• performing frequency multiplication on the received 3d video signal by generating n consecutive frames of the left-eye signal in a first time duration occupied by one frame of the left-eye signal comprised in the received 3d video signal and generating n consecutive frames of the right-eye signal in a second time duration, subsequent to the first time duration, occupied by one frame of the right-eye signal comprised in the received 3d video signal with n being greater than 2,
• wherein, at least one frame of the n consecutive frames of the left-eye signal is a black frame and at least one frame of the n consecutive frames of the right-eye signal is a black frame, each non-black frame of n consecutive frames of the left-eye signal has the same video content and each non-black frame of n consecutive frames of the right-eye signal has the same video content;
• wherein among the n consecutive frames of the left-eye signal, the first frame of the left-eye signal is a black frame, and the nth frame of the left-eye signal is a non-black frame;
• and, among the n consecutive frames of the right-eye signal, the first frame of the right-eye signal is a black frame, and the nth frame of the right-eye signal is a non-black frame;
• and
• driving, by light-emitting diode (LED) driving signals, a panel to display the n consecutive frames of the left-eye signal and the n consecutive frames of the right-eye signal,
• wherein, among the n consecutive frames of the left-eye signal, the second to the (n−1)th frames of the left-eye signal correspond to LED driving signals which are on or off;
• and, among the n consecutive frames of the right-eye signal, the second to the (n−1)th frames of the right-eye signal correspond to LED driving signals which are on or off.
