Today, with the gradual development of modern technology, display technology has also ushered in a significant change. As a representative of future display technology, OLED has many advantages such as thinness, energy saving, and high contrast. This article will explore from many aspects why OLED is the representative of future display technology.

 

1. Working principle of OLED

 

OLED, the full name of organic light-emitting diode, is a non-polar, self-luminous thin film material. The light-emitting principle of OLED is that under the action of an electric field, electrons are injected from the cathode into the organic semiconductor material layer, and electron-deficient holes are added to the anode. The electrons and holes recombine, and they emit light when they meet. While OLED is working, electrons will continue to be injected into the organic semiconductor material layer. This process means that the electron injection area points to the controllable light-emitting area.

Since OLED is a self-luminous material, it has the best brightness performance. In addition, OLED also has high color saturation and more realistic and natural color performance, so it has attracted more and more people's attention.

 

2. Advantages of OLED

 

1. High contrast

OLED has the characteristics of high contrast. In the black area, the OLED display can completely turn off the display, which means that its contrast ratio is extremely high and can present perfect black and true white.

2. High energy efficiency

Due to the light-emitting principle of OLED, it does not consume energy due to the black display area. It does not need to change the light level when the brightness changes like traditional displays, thus reducing energy consumption and making it more energy-saving.

3. Wide viewing angle

OLED displays have a high degree of visibility, and the viewing angle can be greatly adjusted horizontally and vertically, making it easy to view the content on the display from various angles.

4. Slimer screen

OLED displays have slimmer screens. Because OLED is self-illuminating, there is no need to add an additional light source behind it, and the screen can be very thin and light.

5. Faster response time

The OLED display has a very fast response time, ranging from a few microseconds to a few milliseconds, with excellent clarity and visual effects. This is one of the reasons why OLED is better than traditional LCD displays.

 

3. Application of OLED

 

1. Smartphone

OLED is widely used in smartphones. Because OLED consumes less energy than traditional LCD, it can improve the battery life of mobile phones and extend the use time.

2. TV

OLED TV is also one of the very popular products currently. Because OLED has a very high contrast ratio and can perfectly present high black and white colors, coupled with higher pixel density, OLED TVs can provide a clearer, more realistic and high-quality audio-visual experience.

3. Cars

OLED technology is also widely used in the automotive field. OLED can provide more high-level and sophisticated lighting designs that correspond to the appearance of the car and achieve visual coherence, such as all exterior lights, interior instrument panels and entertainment systems.

 

4. The future development of OLED

 

OLED displays have very broad prospects. It has been widely used in smartphones, TVs, cars and even home appliances. As technology continues to develop, OLED displays will become more and more widely used.

In the future, OLED will be more deeply applied in fields such as flexible screens, 3D printing, and nano-biotechnology. It is expected that OLED TV will occupy 40% of the TV market in 2020, and its market competitiveness will be further enhanced. In addition, OLED displays are also expected to be widely developed in fields such as virtual reality and augmented reality.

 

Throughout the full text, we can find that OLED is the representative of future display technology. It is known for its advantages of high contrast, energy saving, high visibility, slimness and fast response time, so it is attracting more and more attention in various fields. With the continuous development of technology, OLED displays will be used in more fields, bringing people a better visual experience. Therefore, we can consider OLED to be the representative of future display technology.
