Part Number: TFP401A-Q1
Other Parts Discussed in Thread: TFP401

Hi team,

We checked SCDT pin in TFP401, its voltage level is low when the panel is no display,

Could you suggest us some methods to check why the SCDT pin always keep low?

Thank you!

Hi Zoe,

If there's no display on the panel then the SCDT pin should be low. Please see the pin description in the datasheet.

Hi Brian,

Sorry but I'm not sure I understand your question here. The SCDT pin is supposed to be low when there's no display on the panel.
