18/24bit RGB

Silk screen	Interface	Function	Interface type
P3	RGB	RGB crystal liquid	Standard 0.5mm FPC seat, 40PIN

RGB crystal liquid is 24bit mode，compatible to 18bit/16bit mode,through which RGB resistance screen panel and RGB capacitor screen panel in different sizes and specifications produced by MYZR can be connected，RGB interface block is build with connector imported，abandon the cheap drawer type produced domestically，which is opposite press type to ensure easier installation,better performance and connectivity.
