Abstract:
A display system includes a display panel, a timing controller, a plurality of source drivers and an EDDS interface. The control signals, the clock signals and the setting signals generated by the timing controller are embedded as protocols into the data signals. The embedded signals are then transmitted from the timing controller to each source driver via a corresponding pair of differential data lines of the EDDS interface. The decoders of the source drivers can then decode the embedded signals for generating corresponding driving signals for the display panel.

The present invention provides a method and apparatus for determining the data transmit diversity mode of a base station. The present invention first estimates a first feedback weight of the mobile unit during a first slot. The first feedback weight has a first phase. Then, the present invention estimates a second feedback weight of the mobile unit during a second slot. The feedback weight has a second phase. A phase difference is obtained by comparing the first phase with the second phase. The present invention determines the applicability of closed loop transmit diversity mode according to the phase difference. Besides, if the feedback error rate is too high, the present invention commands the base station to tune off the closed loop transmit diversity for better performance.
