HI, all

I have question about test pattern of SN65DSI84.
I know the SN65DSI84 is able to be outputted test pattern, when we set CHA_TEST_PATTERN = 0x10.
Is SN65DSI84 possible to be outputted another test pattern?

Regards,
Nao

Hi, Joel

Thank you for your quick reply.
I don't have LVDS panel, so I can't be confirmed in the image now.
Please attach the picture of test pattern, if you have it.

Nao

Hi, Joel

Our customer provide me with the test pattern image on their LCD panel.
I think this test pattern is not good, because left side red area is very thin.
Is this an expectant test pattern from pattern generator in SN65DSI84?

Nao

Hello Nao,
The picture below shows a 1024x600 LVDS panel with the pattern mode enabled. As you can see, the customer's panel has gray bars instead of white bars It seems that they need to adjust the LVDS panel parameters, try changing the HSync Pulse Width.
