Got this Sony recently... something that I had almost 20 yrs ago when I was married. My ex-wife took it. I think the screen is 2.7 inches. It uses one of those weird flat crt's... same was used in many of the portable Sony's of the time.

Works pretty good. The camera doesn't do too well taking pics (considering I was only a few inches from it when I snapped the camera).

I picked up the exact same set this weekend at a community garage sale. $2. Works great. No customer brightness control that I could find though. There is an unmarked focus control underneath the crt though. Seller said it was her ex's tv. Hopefully not a trend.
