| 20110043545 | LED DISPLAY SYSTEM AND DATA-TRANSMISSION CONTROL METHOD OF SAME - A LED display system includes a display controller includes an output/input port; a plurality of driving circuits coupled in series, wherein a first one of the driving circuits is coupled to the output/input port; and a plurality of LED sets respectively coupled to the plurality of driving circuits. A plurality of image data, outputted from the display controller, are shifted to the plurality of driving circuits, respectively, in a first direction through the first one of the driving circuits when the display controller is in a displaying mode; and a plurality of status data, respectively generated by the plurality of driving circuits, are shifted to the display controller in a second direction through the first one of the driving circuits when the display controller is in a detecting mode. | 02-24-2011 |
| 20110043497 | LED DISPLAY SYSTEM AND MODE-DETERMINING METHOD OF SAME - A LED display system includes a display controller including an output port having a first output terminal and a second output terminal; a plurality of LED sets; and a plurality of driving circuits, coupled in series and coupled between the display controller and the plurality of LED sets, respectively. Each of the driving circuits includes a first signal-input terminal, a first signal-output terminal, a second signal-input terminal, and a second signal-output terminal, wherein the first signal-input terminal of a first one of the driving circuits is coupled to the first output terminal, the second signal-input terminal of the first one of the driving circuits is coupled to the second output terminal. The display controller asserts a transition period for switching the driving circuits from a first operation mode to a second operation mode by manipulating a first signal outputted to the driving circuits through the first output terminal. | 02-24-2011 |
