It literally takes thousands of engineers to keep the place running. Each step has to be precisely aligned to the previous one within a few microns. Remember, the average human hair is 40 microns in diameter.” Then you deposit a layer of silicon, followed by a process that builds millions of precisely shaped transistor parts. This patterning step is repeated to build up tiny little cells, one for each dot (known as a pixel) on the screen. On one of the sheets transistor “cells” formed by first depositing a layer of indium tin oxide (ITO), an unusual metal alloy that you can actually see through. That’s how you can get electrical signals to the middle of a screen. “Liquid Crystal display screens are made by putting two thin sheets of glass together. The process to build a TV screen is incredibly complex. The BOE factory, where most US TV screens are made today, is almost a mile long and cost about 7 BILLION dollars to build! Sony, Samsung, LG, Vizio, etc. ![]() Specifically, the BOE Technology factory in Hefei, the capital of China’s Anhui Province. If you bought your TV recently, chances are incredibly high that it came from China. To better understand why your TV screen costs so much, let’s take a brief look at the manufacturing process and what’s involved. ![]() 5.1 Related Posts: Why TV screens cost so much
