WD40 makes for a decent enough solution for this purpose if the display assembly doesn't open and close relatively freely. Partially due to this reason:

WD-40’s ingredients are a secret. The makers avoided revealing its ingredients by not filing for a patent, but it is known to consist of oil suspended in a volatile hydrocarbon. When WD-40 is sprayed, the suspended oil can get into crevices where the hydrocarbon evaporates, leaving behind the oil lubricant. Every surface has some degree of imperfection at the molecular level. The long hydrocarbon chains in oils and grease serve to provide a layer between the two surfaces and help them move over each other easily. WD-40 was not originally designed as a lubricant so it is actually not the best lubricant to use on a fast moving mechanical part like a bicycle chain.

In a nutshell, it's an oil that can get into tight spots. Like a notebook hinge. It's a decent enough start when it comes to the relatively difficult task of freeing up tension in the hinge assembly.

Eventually I found a synthetic anti-seize oil called Nulon L90 used in the manufacturing of engines that worked relatively well, and so it should, considering it's designed to free up camshafts rotating at speeds of up to 3500rpm for a typical 7000rpm redline engine. Downside was the thickness but considering only a fraction of the applied amount made it to the inside of the clutch assembly, it worked extremely well for the purpose.

I'm not sure if i'd recommend it again though based on the price and the lack of any long-term testing when used on notebook hinges.
