The present invention provides a data processing method, apparatus, and LED TV for use in an LED TV. The data processing apparatus performs a method conversion on the received TV signal to obtain a first video signal having a preset method, and is connected to the signal processing chip to perform clock synchronization processing on the first video signal to perform a second video signal. And a video processing chip for outputting the second video signal to the LED display. According to the present invention, it is possible to solve the problem that the LED TV can display only a single TV signal in the existing technology, and realize the effect that the LED TV can display a video of various methods and formats.
