Part Number: DS90UB941AS-Q1

Hello,

When using DS90UB941+DS90UB948 for application, the LCD 10''  appears  , and the 12'' LCD appears flower screen. Please refer to the output of 12''　LCD。

It works in single link mode. Do you have any other opinion?

Best regards

Kailyn

    From this picture, it sounds the video data is damaged either by processor's receiver or by FPD-Link receiver.

    For the FPD-Link receiver, you can check 948's lock pin, does it have any issue to indicate the link is broken due to bit error?

    if yes, you can check the system application, such as board layout, channel parameters(connector, cable) etc.
