Abstract:
A LED driving system for a LED matrix having a plurality of LEDs connected in parallel. The LED driving system includes a plurality of driving modules. Each one of the plurality of driving modules drives a corresponding one of the plurality of LEDs. The plurality of LEDs are divided into a plurality of groups. The plurality of driving modules drive the plurality of LEDs ON successively group by group. In each one of the plurality of groups, the LESs are driven ON successively row by row, and for each row in each one of the plurality of groups, the LEDs are driven ON successively column by column with a programmed delay time between the LEDs in every two successive columns. Each one of the plurality of driving modules can include a grayscale control module for adjusting a brightness of the corresponding one of the plurality of LEDs.

Claim (Index 16):
The LED driving system of  claim 15 , wherein:\n for each c=0, 1, . . . , N\u22121 and r=0, 1, . . . , M\u22121, the DRV(c, r) comprises a local grayscale control module having a clock input terminal configured to receive a clock signal and a Q-bit input terminal configured to receive the programmed grayscale command value for the LED(c, r), wherein the programmed grayscale command value for the LED(c, r) comprises Q bits; and wherein the local grayscale control module comprises a Q-bit grayscale command register, configured to receive and refresh the programmed grayscale command value for the LED(c, r) by every Y dimming frames, wherein Y is an integer greater than 0, and wherein one dimming frame lasts for 2 Q  cycles of the clock signal, and wherein the Q-bit grayscale command register is further configured to transfer the programmed grayscale command value for the LED(c, r) of a current Y dimming frames to a Q-bit counter, and further configured to clear the programmed grayscale command value for the LED(c, r) of the current Y dimming frames once it is transferred to the Q-bit counter to receive the programmed grayscale command value for the LED(c, r) of a next Y dimming frames; and the Q-bit counter, configured to receive and store the programmed grayscale command value for the LED(c, r) of the current Y dimming frames, and to decrease the programmed grayscale command value for the LED(c, r) of the current Y dimming frames by counting down by one at each cycle of the clock signal until the Q-bit counter counts to 0.
