OLED is the abbreviation of "Organic Light Emitting Display", also known as organic light-emitting display screen, it uses organic light-emitting technology, this is the latest display technology, OLED display technology is different from the traditional liquid crystal display, it does not need backlight, but uses a very thin organic material coating and glass substrate, when there is an electric current passing through, these organic materials will glow, so it has a large viewing angle. The contents of the screen can be seen clearly from all directions, and can be made very thin, and the OLED display screen can significantly save electricity, known as the "dream display".
But OLED is not without shortcomings, because it is still an immature technology, so at this stage, its service life is still relatively short, the screen area is also relatively small.
