OLED:Organic
OLED: organic light emitting display, or organic light emitting display, is a new emerging category in mobile phone LCD, known as "dream display". OLED display technology is different from the traditional LCD display mode. It does not need backlight. It uses very thin organic material coating and glass substrate. When there is current passing through, these organic materials will emit light. Moreover, OLED display screen can be made lighter and thinner, with larger viewing angle, and can significantly save power. However, although OLED with better technology will replace TFT and other LCDs in the future, organic light-emitting display technology still has some defects, such as short service life and difficulty in large-scale display. LED is the abbreviation of light emitting diode. LED applications can be divided into two categories: one is led single tube applications, including backlight LED, infrared LED, etc; The other is led display. At present, there is still a certain gap between China and the world in the manufacturing of LED basic materials. However, as far as LED display is concerned, China's design and production technology level is basically synchronized with the international level. LED display screen is a display device composed of light-emitting diodes. It adopts low voltage scanning drive, and has the following characteristics: low power consumption, long service life, low cost, high brightness, few faults, large viewing angle, long visual distance and so on. More specifically, look at this address http://ask.so1ba.com/A/8045/18734.html reference material. In fact, they are all liquid crystal displays, but led is backlight technology, and TFT is a kind of material containing toxic element Hg before.
