Description
The Chipone ICND2065 converts serial input date into the gray scale of each pixel by a 16-bit shift register. ICND2065 detects individual LED open errors without extra components. ICND2065 also integrated pre-charge circuit for ghosting reduction.
The ICND2065 exploits precise current regulation technology, with both channel-to-channel error and chip-to-chip error less than +/- 2.0%.
