Compare Digital Photo Frame Prices

Is it same to buy a digital Photo Frame or a LCD TV?
Basically I want to display jewelry photos in my showroom via either TV or Digital Photo Frame…my main concern is which one will be lesser in price…. secondly, Which one will be more better to buy since we are displaying pict that require best resolution and sharpness…..how much is the life of a digital F when compared to a LCD TV?
