Display panel manufacturers are companies that are able to produce the cell structures needed in OLED and LCD displays. Not monitor or TV manufacturers.
For LCD displays, the cell includes a front layer with contrast coating, a polarizing film, color, liquid crystals, a thin-film transistor (TFT), and a polarizing film.
For OLED displays, the cell includes a front layer with contrast coating, color filters, OLED panel, and substrate.
cell of lcd and oled, only few big manufacturers can make it
In both LCD and OLED displays, producing these cells – which are highly complex – is by far the most difficult element of the production process. Indeed, the complexity of these cells, combined with the levels of investment needed to achieve expertise in their production, explains why there are less than 30 companies in the whole world that can produce them. China, for instance, has invested more than 300 billion yuan (approximately $45 billion USD) in just one of these companies – BOE – over the past 14 years.
