While there was a strong push for IPS LCD screens, there were high quality TFT screens: my 2009 Sony Vaio VGN-Z had one (and even used LED backlighting).
I was never bothered by the colour reproduction or off-axis viewing for regular work, but it did have the privacy effect they are trying to replicate today.
FWIW, I never really understood the IPS and viewing angle obsession for work screens (laptops/desktops), but I guess decent TFT screens with at least 10 degree angle stability were hard or expensive to procure.
IPS displays are TFT. AMOLED displays are TFT as well. TFT is a technology for manufacturing transistors (the switching elements in a display). Using vapour to deposit layers of materials on a substrate (like glass in the case of displays). Perhaps you mean TN displays.
No, a TN display is nowhere near private enough. Your neighbour in an aeroplane, for example, can easily see what you're working on. The angles are not that bad (certainly on anything even remotely close to being called a good display) and wonky colours don't provide privacy unless it's colour that you're trying to keep private. Text is typically easily readable. I think they used to specify something like 160° horizontal viewing angle. Like 15 years ago.
