Abstract: The present application discloses a method and an apparatus for controlling transmission of a VBO signal and a display terminal. The method is applied in the display terminal, where the display terminal includes a mainboard and a Tcon board which use a VBO interface for communications, and the method includes: after a system is powered on, performing multiple interactions between the Tcon board and the mainboard according to a VBO signal transmission protocol; after each of the interactions, acquiring, by the Tcon board, a timing control signal by parsing valid image data of a received VBO signal transmitted by the mainboard, and if the timing control signal acquired by parsing successively satisfies a preset condition in a preset number of handshakes, then stopping repeating the interaction, and only performing transmission of display image data in the VBO signal.

Abstract: Disclosed are a controlling device and method for frequency synchronization as well as a LCD TV. The method is applied to an LCD TV, wherein the LCD TV includes a front-end motherboard chip, a main drive control chip and a plurality of column drive control chips, the method includes: when the main drive control chip recognizes that its operating frequency is unstable, it generates a clock turn-off signal; the main drive control chip transmits fixed data to each column drive control chip according to the clock turn-off signal and receives a clock training request initiated by each column drive control chip according to the fixed data; and when recognizing that the operating frequency synchronizes with a frequency corresponding to front-end data transmitted by the front-end motherboard chip, the main drive control chip responds to the clock training request and transmits clock training data to each column drive control chip.
