What Is The Difference Between The Light-emitting Principle Of OLED And LED Light-emitting Board
Apr 10, 2021
Today, the LED light-emitting board market is saturated, the price war is intensifying, and the profit margin is constantly being compressed. Under this background, OLEDs are born at the right time, providing broad prospects for the majority of businesses to open up new markets. Then, what is the difference between OLED and LED light-emitting panels, and what are their light-emitting principles, let's discuss them together. a bit:
The LED light-emitting panel uses metal materials, while OLED uses organic materials. The light-emitting principle of the two is the same. The difference is that OLED does not need a backlight and emits light by itself, which is composed of a light-emitting diode array. The brightness is higher than that of the LED liquid crystal, and the thickness is thinner. It is a substitute for the LED liquid crystal screen in the future. The LED LCD screen needs a backlight source, the brightness is average, and the display degree is low in sunlight, but it is currently the most widely used.
LED light-emitting board applications can be divided into two categories: one is LED single tube application, including backlight LED, infrared LED, etc.; the other is LED display. At present, there is still a certain gap between China and the international in LED basic material manufacturing. , But as far as LED displays are concerned, the level of design and production technology in China is basically in line with the international level.
The LED display screen is a display device composed of light-emitting diodes arranged in an array. It adopts low-voltage scanning drive and has the characteristics of low power consumption, long service life, low cost, high brightness, low failure, large viewing angle, and long visual distance.
OLED: Organic Light Emitting Display, or organic light-emitting display, is a newly emerging category in mobile phone LCD, known as the "dream display." OLED display technology is different from traditional LCD display methods. It does not require a backlight. It uses very thin organic material coatings and glass substrates or special plastic substrates. When current passes through, these organic materials will emit light. Moreover, the OLED display screen can be made lighter and thinner, with a larger viewing angle, and can significantly save power. However, although OLEDs with better technology will replace LCDs such as TFTs in the future, organic light-emitting display technology still has shortcomings such as short service life and difficulty in large-scale screens.
