18/24bit LVDS0

silk screen:J20
LVDS0 crystal liquid is 24bit mode,compatible to 18bit mode,through which LVDS resistance screen panel and LVDS capacitor screen panel in different sizes and specifications produced by MYZR can be connected, LVDS0 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.
