Abstract
The present invention provides a differential signal interfacing device, including a reduced swing differential signaling (RSDS) transmitter and a plurality of RSDS receivers, in order to improve RSDS signal capacity. The RSDS transmitter is coupled to the plurality of RSDS receivers via a bus and transmits a RSDS signal in a discontinuous manner. The plurality of RSDS receivers receives the RSDS signal for signals of different types.
Claims12
A display device for improving internal transmission efficiency, the display device comprising:
- a timing controller for generating a plurality of data signals and a plurality of start-up signals;
- a plurality of source drivers coupled to the timing controller;
- a differential signal transmitter installed in the timing controller, for discontinuously transmitting a reduced swing differential signaling (RSDS) signal comprising the plurality of data signals and the plurality of start-up signals;
- and
- a plurality of differential signal receivers installed in the plurality of source drivers, for receiving the RSDS signal;
- wherein the differential signal transmitter stops transmission between one of the plurality of the start-up signals and one of the plurality of the data signals for a corresponding source driver of the plurality of the source driver to determine a type of the received RSDS signal and wherein the differential signal transmitter transmits to the corresponding source driver the start-up signal first and then the data signal in the order.
A method for improving internal transmission efficiency of a display device, the method comprising:
- a timing controller of the display device generating a plurality of data signals and a plurality of start-up signals;
- wherein the plurality of the data signals and the plurality of the start-up signals are reduced swing differential signaling (RSDS) signals;
- and
- a plurality of source drivers of the display device receiving the plurality of the data signals, and the plurality of the start-up signals from the timing controller;
- wherein the timing controller stops transmission between one of the plurality of the start-up signals and one of the plurality of the data signals for a corresponding source driver of the plurality of the source drivers to determine a type of a corresponding received RSDS signal.
