SN65DSI86: Dynamic Framerate Sense/Change Function

Jim CHEN

Part Number: SN65DSI86

Hi Team,

Our panel has two different frame rate (high and low) in EDID, the system in idle state will request the panel to enter low refresh rate.

So we would like to know if DSI86 can support dynamic framerate sense/ change function or not?

Thanks.

No, The DSI86 does not support dynamic framerate changes.

Could DSI86 change the framerate by other way? I mean maybe rest the DSI86 first, then re-connect the link and change the framerate, like that.

I am mistaken, the DSI86 doesn't care about frame rate. Are you changing the DSI clock when you are changing the framerate? Also you don't need to relink train when you change resolution or frame rate.

Qualcomm tells that they could dynamically increase/decrease the blanking area to change the framerate

Could you provide the email address? I would like to create a mail thread with Qualcomm engineer to discuss this topic.

Thanks,

Hampton
