DS90UB928Q-Q1: Screen flicker at low temperatures

Part Number: DS90UB928Q-Q1


 

Hi team

DS90UB928-Q1 works normally at room temperature, but screen flickering occurs at -20 ° C. The customer suspects that this is due to poor LVDS signal output from UB928, but the customer does not have equipment to test the LVDS signal. The attachment is a partial schematic diagram of UB928. Please help analyze the reasons. Thank you!
