With the advent of the intelligent era, cars are becoming increasingly intelligent. As part of the car entertainment system, car display screens play an important role. From early CRT displays, to later TFT-LCD displays, to today's OLED displays, automotive displays are also constantly being upgraded. Among them, OLED automotive displays have attracted much attention due to their characteristics such as high contrast, high brightness, and fast response. Based on different performance and price, this article will conduct a comprehensive evaluation on how to judge the cost-effectiveness of OLED automotive displays.

 

1. Technical principles and development overview of OLED automotive displays

 

1.Technical principles

OLED is an organic optoelectronic semiconductor material that converts electrical signals into optical signals through the principle of direct electroluminescence to achieve display effects. OLED has a self-luminous effect and does not require a backlight panel. It can achieve thinner, lighter, more flexible, higher contrast, and faster display effects.

 

2. Development overview

 

The development of OLED began in the 1980s, when the range of applications was still limited. In the 1990s, as organic semiconductor technology continued to mature, OLED began to be gradually used in automotive displays, mobile phone screens and other fields. In the 21st century, OLED technology also has advantages over other display technologies and has begun to become popular.

 

2. Performance characteristics of OLED automotive displays

 

1. High contrast

 

The contrast ratio of OLED is as high as 100,000 to 1, while the contrast ratio of ordinary TFT-LCD displays is only about 1,000 to 1. The OLED display has bright colors and clear details, which can bring a richer visual experience.

 

2. Faster response

 

The response speed of the OLED display is very fast, which can achieve faster picture changes. Even if the picture outline changes sharply at high speed, it can still show a clear picture.

 

3. More energy efficient

 

OLED displays consume less power, can achieve higher energy-saving effects, and also reduce unnecessary power consumption such as unclustering, making them more environmentally friendly.

 

3. Types of OLED automotive displays

 

1.AMOLED

 

The full name of AMOLED is Active-Matrix Organic Light-Emitting Diode, which is active matrix OLED. That is, in the OLED structure, each pixel has an independent transistor, and almost every pixel has a conductive element. Compared with PMOLED is brighter and more vivid.

 

2.PMOLED

 

The full name of PMOLED is Passive-Matrix Organic Light-Emitting Diode, which is passive matrix OLED. It is a low-resolution OLED display that uses the mechanism of conductive flight to apply operating voltage to the entire column of pixels to achieve display. It has a low resolution and fewer screens, is also prone to shadows, and has uneven pixel alignment.

 

4. How to judge the cost performance of OLED automotive display

 

1. Price

 

The price of OLED automotive displays is higher than that of traditional TFT-LCD displays, but as the technology continues to mature, the price is gradually declining. From a consumer perspective, we need to evaluate the price based on our own needs and other factors.

 

2.Brightness and contrast

 

OLED automotive displays have higher brightness and contrast, providing a more comfortable viewing experience. In addition, improvements in brightness and contrast have little impact on energy consumption, so better energy savings can be achieved.

 

3. Resolution and response speed

 

OLED automotive displays can achieve higher resolution and faster response speed, which is also one of its advantages. From a cost-effective perspective, high resolution and faster response speed can bring a better visual experience, but we also need to make a choice based on our own needs.

 

4.Manufacturer

 

The technical level and quality of OLED automotive displays produced by different manufacturers will also be different. Therefore, we need to choose manufacturers with high credibility, good technical level, and reliable quality to purchase.

 

5.Power supply

 

The power supply condition of the car also affects the performance of the OLED automotive display. Therefore, we need to consider the stability of the vehicle's power supply and install it reasonably to ensure the normal use of the OLED automotive display. In addition, we also need to ensure the safety and reliability of automotive circuits.

 

5. Future development trends of OLED automotive displays

 

OLED automotive displays have huge development potential and are expected to become the mainstream development direction of automotive displays in the future. With the continuous development of technology, the price of OLED automotive displays will gradually decrease. At the same time, they will also be more stable, more resistant to high temperatures and vibrations, and more suitable for the requirements of the automotive environment.

 

As can be seen from the above comments, OLED automotive displays have the potential to be highly cost-effective, and buyers also need to make reasonable choices based on their own needs. When choosing an OLED automotive display, we need to make a judgment based on comprehensive factors such as brand, price, resolution, response speed, and brightness. We also need to consider the safety and actual use of the automotive electrical circuit. In short, choosing an OLED automotive display needs to be customized and consider many factors to better meet actual needs and expected effects.
