As OLED technology continues to advance, the automotive industry has gradually begun to adopt OLED displays, becoming a future trend. In the future automotive industry, OLED displays will become a disruptor in the automotive industry and a revolutionary technology. This technology is not only more energy-saving, but also able to meet consumers' needs for visual creativity. Therefore, it has incredible market potential and will have a profound impact on the automotive industry.

 

1). OLED technology and its characteristics

 

The full name of OLED in English is "Organic Light-Emitting Diode". Its basic structure consists of several layers such as a fluorescent layer, a proton electron transport layer, anode, and cathode. When a current passes through the fluorescent layer, the flowing current in the fluorescent layer and the light released when electrons and holes are recombined combine to emit light, forming a display effect.

 

The biggest feature of OLED technology is that it does not require a backlight. It has many advantages such as extremely thin and light, fast response, ultra-low energy consumption, bright colors, realistic display effects, and long life. It can also be made into flexible, curved, transparent and other special forms of displays. , providing a broad space for innovation for modular technology and highly interactive interactive systems.

 

2). Current status of OLED automotive display applications

 

In recent years, as part of high-tech cars, the technology configuration in cars has gradually increased, and OLED display technology has also been gradually applied to the automotive industry. This technology enables automotive displays to have higher transparency and color vividness, richer contrast and brightness, better viewing angles and response speeds. At the same time, OLED technology also has high color temperature sensitivity and higher lighting efficiency. Higher obvious advantages.

 

According to reports, the in-car screen of Mercedes-Benz EQS uses an OLED panel with a size of up to 142.9 cm and a horizontal panel width of 54 cm, which is larger than ordinary OLED TVs. In addition to the information provided by the EQS Internet of Vehicles function and other information such as vehicle status, drivers can also choose the color of the ambient lighting in the car to make the atmosphere in the car more warm and comfortable.

 

3). Advantages of OLED automotive displays

 

Cars are something that car owners come into contact with every day, and their look and feel and user experience are of great significance. The changes brought by OLED technology to cars can also better meet consumers' diverse needs for use in cars. So, what are the advantages of OLED automotive displays compared to traditional automotive displays?

 

1. More accurate color restoration

 

The main principle of cLED display color display is based on the combination of three primary colors (red, green, and blue) to present various colors. But in terms of color accuracy, the gap between OLED technology and cLED technology is particularly prominent. The NTSC color range contained in OLED (accurately DCI-P3) can reach more than 99%, the response time is only a few hundred microseconds, and the display effect is more gorgeous and detailed. and vivid.

 

2. Lower energy consumption and longer life

 

The light-emitting principle used in the display effect of OLED technology does not require an external backlight and is more energy-saving than imaging tubes. This means that OLED can use energy more efficiently and convert electrical energy into light energy, avoiding the problems of traditional liquid crystal displays. Light leakage effect. In addition, the life of OLED is more than five times longer than that of traditional displays, reducing the lifetime cost of replacement and repair.

 

3. Better response speed

 

Compared with ordinary liquid crystals, OLED technology has advantages in response speed and clarity, because OLED is a self-illuminating source and the response speed can reach a fast millisecond level. This means that when car owners watch videos, play games, and adjust various settings in the car, they will not be affected by delays and freezes.

 

4. Flexibility, transparency, etc.

 

OLED technology does not require an external backlight and has higher flexibility. It can be made into a flexible curved screen, achieving unlimited deformation, and can be easily assembled with other components and installed in various positions inside the car. In addition, transparent OLEDs can also be made, which is a novel and practical design that can provide in-car entertainment and information services such as navigation and movies without affecting the driver's line of sight.

 

4). Market prospects of OLED automotive displays

 

Cars are an indispensable means of transportation in everyone's life, and the development of OLED technology has made the display screen inside the car no longer a part of the traditional car configuration, but has begun to become a full-featured multimedia, entertainment, and information interaction tool . The potential large market demand, powerful features and broad application prospects also make OLED technology as a display medium for automotive displays the future development direction of the automotive market.

 

At present, OLED technology is becoming increasingly mature in the automotive industry and is actively penetrating into the high-end market. Automakers such as Volkswagen and Audi in Germany and Honda and Toyota in Japan have all adopted OLED technology as standard equipment for their high-end models. It is expected that the automotive display market will reach more than 100 billion US dollars by 2025, and OLED displays will occupy a significant share of it.

 

5. Future Outlook

 

The application potential of OLED technology in the automotive industry is unlimited. Its application scenarios are not only limited to in-car entertainment display and control. OLED displays can also become an important navigation and information medium during car driving. With the continuous development of technology, Cars will pay more attention to interior design with technical attributes to cater to consumers' needs for dynamics and technology.

It seems that OLED technology will be widely used in in-car infotainment, navigation functions and other aspects. In the future, OLED displays are expected to become a standard feature of smart cars and new energy vehicles, becoming a disruptor in the automotive industry and a promoter of technological innovation.
