Hi, Ti:
      When ds90ub948 input FPD-Link video signal is not a white picture, under what circumstances will the output LVDS signal be a pure white picture?

    您好，输出白屏我想可能和FPD  link data mapping不匹配有关，导致不能正常显示。

    参考数据手册7.4.3 OpenLDI Output Frame and Color Bit Mapping Select部分的介绍。MAPSEL为高低电平决定了是OLDI/SPWG/VESA还是JEIDA 格式。

    可以参考下Figure 7-18~Figure 7-25的data  mapping。
