This is actually what I meant by "merged together". They are two separate displays controlled by separate computers, with separate power supplies etc. During normal mode operation they're synchronized somehow and can draw a large image over the entire display area, but in emergency mode you can display crucial flight data on only one of them if the other stop working. I have never really thought much about it, but I guess the actual LCD thingie is manufactured in one piece and the control signals just being split between different computers somehow, but I don't know anything about how these things are made! :)

Here's a paper on a redundant display for military aircraft. Each LCD panel has redundant inputs, driver circuits, and power supplies. The two displays are built on a single LCD substrate, so there is no line between the two. https://www.mrcy.com/resourcehub/displays/dual-redundant-display-in-bubble-canopy-applications https://www.mrcy.com/resourcehub/displays/dual-redundant-dis... https://www.mrcy.com/legacy_assets/siteassets/product-datasheets/mission-computing-and-avionics/displays/2150-display-series-datasheet.pdf https://www.mrcy.com/legacy_assets/siteassets/product-datash...
