Transflective + capacitive panel?

Please forgive me if this is a dumb question, but I see a lot of posts about people wanting capacitive screens and posts about people wanting transflective screens, but I never see anything about somebody using both together. I'm curious if there's a technical reason for this as I'm in the planning stages of building a carpc and considering which route I want to go as far as my monitor is concerned. Searching has turned up very little in this regard.

Can anyone give me a reason, besides cost, why it doesn't make sense to take advantage of both technologies simultaneously? Does one negate the benefits of the other, etc? Any thoughts would be appreciated!

Of course it would be nice to have this, but until it is offered people have to live with what they can get.

So does this mean there's no technical limitation on incorporating both? It's simply due to a lack of manufacturers offering the option?

Basically yeah as far as i am aware.
Or the ones that do exist are too expensive for the typical user..
