How and where are the displays mounted in our gadgets? When looking at new TVs, notebooks, tablets, smartphones or smart watches, we do not ask this question, because the answer is not important to us. However, it can not be hidden that the quality of the screen largely affects whether we choose to buy one of the aforementioned devices or not. And if we decide on one of them, then there is a good chance that his matrix was made in the LG Display factory, which I had the opportunity to see with my own eyes.
Different types of displays are now so popular that we are no longer wondering how complex their production is and how to appreciate the technology behind it. And shame, because even the smallest and worst screen is the result of many people’s work and the result of almost hypnotic electronic ballet created by collaborating robots.
One of the best places to enjoy this ballet is the LG Display factory complex in South Korea’s Paju. This is where, on an area of 1.7 square kilometers, there are three modern display factories (P7, P8 and P9) and a research center with a total workforce of around 17,000. This is where the best LCD displays used in the largest LG televisions, such as 105-inch curved monsters, and all OLED TVs (the only place in the world where such large OLED panels are produced).
The whole complex in Paju (including residential space and other LGs owned by the company) has a total area of less than 5 square kilometers and resembles a small town where around 7,000 people live each day. And all this to ensure the best conditions for production lines, where the main characters are huge and very delicate glass sheets of thickness of only about 0.5 mm.
Factory P7 operates on glass panes of 1950 x 2250 mm, and P8 and P9 factories on panels of 2200 x 2500 mm, ideally suited for creating 55 “diagonal panels (one 55-inch matrix is made of one glass pane). These huge glass sheets are applied to the next layer of the display. All this is done under very sterile conditions, the maintenance of which requires the use of an extensive ventilation system occupying a large part of the factory building.
The Paju pride is the previously mentioned large OLED matrices, but in this technologically advanced town, …
