RT5988 is an 8-channel N-MOS for common cathode LED display application. Built-in the 8-bit shift register, RT5988 makes the data transfer by serial connection without decoding component on board to simplify the PCB layout.
By giving a very simple control model to let controller determined the turn-on, pre-charge, and row blank timing, the RT5988 can effectively to eliminate the LED ghosting phenomena, to remove LED bright line caused by a LED short or open, and also to avoid the over reverse voltage to damage LEDs in order to raise the display performance.
