I work in the automotive industry, where we often use fancy unusual screen hardware a couple of years before it turns up in home consumer electronics or phones. For example special multi-axis curved stuff, dynamic angular privacy filters, or haptic feedback using electrostatic modulation of resistance instead of vibration motors (that allows you to make the screen feel rough and scaly or glidy, give UI elements a feel-able shape, etc.).

One time, we were told to use earplugs at work for a few days, because of a pre-release firmware bug that could in theory, if other safety mechanisms also failed, cause the haptics to potentially emit an ear-piercing low-frequency tone ...

Temporary EDID bugs, otoh, I've seen so many times. :)
