Speaking of the smart TV market, there are more and more brands, and the prices are getting cheaper and cheaper. I am also a 3,000-piece, 50-inch micro-whale TV. 
From the interface point of view, smart TVs are much more simplified. 
Not much to say, see folding machine. From the point of view of the circuit board, the internal structure of the smart TV is now simpler than the computer.
