Can we make taller display (>6 rows) without Rotating any Panel upside down?

[anandrajgupta]

Hi Mr. @hzeller,
First of all, Thank you.

There is a problem if we rotate an LED panel upside down, water enters the display!

This is because there are few holes in the bottom side of individual LED matrix Panel which is designed for water outlet in case some minor amount of water enters the Panel and there are no such holes in the top side of Panels to prevent rainwater from entering the Panel from top,
Now, if we rotate the Panel (to use "U-mapper" for taller display having row count greater than 6) then the bottom side comes up thus the bottom holes also come up which causes a lot of water to enter in the Display and no holes in bottom to let the water out from the Display!
That's why I am thinking of a solution to accomplish taller display without turning any Panel upside down, is it possible anyhow?
Note: "V-mapper" can't be used because panels per row is > 10

I am using Compute-Module 3
I have prepared Active-6 HAT
Everything is working fine, it's just the water inlet due to inversion of LED Matrix Panels
What I am trying to achieve can be clarified by the following Diagram:

Please let me know if this is possible anyhow.

Note: I have an idea to accomplish this, but I don't know how to implement that, I am thinking to connect an FRC from the "Output connector of last Panel of 1st Row" to the "Input connector of 1st Panel of 2nd Row" shown in below Diagram, please have a look and help me if possible:

Thank you very much to this awesome community...

Did You tried? Pictures,

• define screen width, height
• parallel = 3
• chain = 6

try this, then picture

NOTE: do You tried your panels individually?

Best regards

thank you for your time.

are you sure you read my problem carefully...

Are You sure you read the entire options of this github carefully?

[davemaster]

3 parallel, not possible (I'm saying that above) BUT, You can programme it, so you're software reorder the image, or build your own mapper

resolution of your panels?

Come on, use 128 x 64

@anandrajgupta My PR should support it (kind of): #1478

But it is only slightly tested, ping me if you need help.

You will probably have problem with long FRC cables, so some zig-zag arrangement may be necessary
