They're not more expensive _just_ because of the lack of ads subsidization.

They also generally are just better built. The expected hours of operation and MTBF of the components is generally much higher than consumer displays. Many of the ones I dealt with had metal cases and stronger glass.

They're expected to stand up to much more abuse or often be installed in places where they're inconvenient to service.

If you wanted to build a non-smart panel with the expected lifespan of a typical consumer TV a significant portion of the current cost could likely be cut if it were done at scale.
