What is an organic light-emitting diode

OLED is the abbreviation of Organic Light EmitTIng Diode in English, and it is translated into organic light emitting diode in Chinese. Because of its thin, light, and power-saving features, since 2003, this display device has been widely used in MP3 players. For DC and mobile phones that are also digital products, OLED has only been demonstrated at some exhibitions before. The engineering samples of the screen have not yet entered the stage of practical application. However, the OLED screen has many advantages that are unmatched by LCD, so it has also been favored by people in the industry.
Below we summarize the advantages and disadvantages of OLED technology for you.
The advantages of OLED:
1. The thickness can be less than 1 mm, only 1/3 of the LCD screen, and the weight is lighter;
2. The solid-state mechanism has no liquid substances, so the seismic performance is better, and it is not afraid of falling;
3. There is almost no problem with the viewing angle. Even when viewed from a large viewing angle, the picture is still not distorted;
4. The response time is one-thousandth of LCD, and there will be no smearing phenomenon when displaying moving pictures;
5. The low temperature characteristic is good, it can still display normally at minus 40 degrees, but the LCD cannot do it;
6. The manufacturing process is simple and the cost is lower;
7. Higher luminous efficiency and lower energy consumption than LCD;
8. It can be manufactured on substrates of different materials, and can be made into a flexible display that can be bent.
Disadvantages of OLED:

1. The lifespan is usually only 5000 hours, which is lower than the LCD lifespan of at least 10,000 hours;
2. Mass production of large-size screens cannot be achieved, so it is currently only applicable to portable digital products;
3. There is a problem of insufficient color purity, and it is not easy to display bright and rich colors.
