There teardown folks at iFixit found that thinner ribbon wires used in the new MacBook Pros compared to their predecessors means they are more likely to fail over time.
"The issue is fairly simple: the current generation of MacBook Pro laptops (2016-present) uses flexible ribbon cables to connect the display to a display controller board beneath the Touch Bar," said iFixit's Taylor Dixon.

"[...] they're subjected to the stress of bending with every opening and closure of the laptop. Within a seemingly short time, those cables are starting to fatigue and tear. The backlight cable is generally the first to go, producing the infamous 'stage light' symptoms [...]"

"When it first debuted, the design seemed fine. But as always, the devil is in the details. Apple opted for thin, fragile flex cables as opposed to the beefier wire cables used in previous designs that could be routed through the hinge instead of wrapped around it, helping mitigate the stress of repeated openings and closings."

iFixit reports that Apple may have already taken steps to reduce the likelihood of 2018 MacBook Pro users experiencing display lighting issues dubbed Flexgate. Affected machines could see uneven lighting that looks like a "stage light" effect with the display potentially failing completely over time.

iFixit was tipped off by MacRumors forum user Olivia88 posting in our Flexgate megathread that their 2018 13" MacBook Pro appeared to have a longer cable than previous models
iFixit speculates that this could prevent some of the wear and tear that had previously caused the failure though they weren't able to say for certain.
