The optional Dithering feature can reduce 24-bit RGB to 18-bit RGB. The optional Look Up Table (Three X 256 X 8 bit RAM) is provided for independent color correction. 18-bit Bufferless displays from QVGA (320 x 240) up to >VGA (640 x 480) pixels are supported. The interconnect is reduced from 28 LVCMOS signals (RGB888+V+H+DE+PCLK) to only 3 active differential signals (DD0P/M, DCP/M, DD1P/M) with the LM4312 Serializer and companion LM4310 Deserializer easing flex interconnect design, size constraints...
