With the continuous progress of liquid crystal display technology, OLED, mini led and micro led have always appeared in the public view. The popularity of these three technologies only increases, and each technology has obvious advantages and limitations. How should we layout the vehicle industry? Today, I will briefly introduce the differences of the three display technologies and the application trend in the field of vehicle display in the future.

01

OLED

OLED, also known as organic light-emitting semiconductor, belongs to a current type organic light-emitting device. When the anode and cathode electrons meet in the light-emitting layer, they produce visible light. It has the advantages of good display effect, low power consumption, high flexibility and ultra thin.

At present, it is widely used on the screen of automotive electronics and consumer electronics. The disadvantage is that it is easy to burn the screen, and the characteristics of organic materials can easily lead to life problems.

02

Mini LED

Mini led, also known as "submillimeter light emitting diode", refers to LED with grain size of about 100 microns. It is an emerging technology that has suddenly become popular in recent two years.

In short, it is an improved version based on the traditional LED backlight, which is composed of a certain number of color or black-and-white pixels, which are placed in the light source or reflective environment light source.

Its backlight bulb is smaller, which can be matched with flexible substrate to realize curved display design, improve screen brightness and contrast, and increase application flexibility.

03

Micro LED

Micro LED is a miniature and matrix LED technology. It has many similarities with OLED. It is composed of light-emitting diodes and adopts the form of self illumination.

Micro LED is to thin film and miniaturize the backlight, which can make the LED unit less than 50 microns. It has greater advantages in brightness, resolution, contrast, energy consumption, service life, response speed and thermal stability.

Micro OLED uses monocrystalline silicon wafer as the backplane, which has the advantages of making the display lighter and shorter, less power consumption, self luminescence and high luminous efficiency. It is also regarded as the next generation of revolutionary display technology, but the disadvantages are also obvious. Due to the immature technology, it is difficult to produce and the yield is low.

summary

1. OLED technology is relatively mature with low cost and can realize mass production

2. Mini led and micro LED are in the early stage of development and have high cost

3. After the popularization of new display technology, the cost will drop and the market will be broad in the future

04

Application in the field of on-board display

From the development trend of vehicle display screen, whether it is single screen, large screen or the recent rise of dual screen and 3D curved screen, we can see the continuous upgrading of the screen in the automotive field.

For the on-board screen, reliability is the first consideration standard, followed by display degree, which is used to ensure normal use in harsh environment.

In the new display market, mini led and micro led have more advantages than OLED. At present, these two technologies have become the highlights of the display industry and attracted much attention.

Due to the immature technology of micro led, the application cost is too expensive and mass production cannot be realized temporarily. Therefore, mini LED has become an alternative technology of micro led.

Compared with micro led, the most significant point is that mini LED technology is less difficult and easier to achieve mass production, which also fully shows that the production cost of mini led still has room to decline.

After several comparisons, mini LED can be said to be the most suitable for rapid development at present, and is expected to be widely used in the field of vehicle.

In the future, the design of on-board display screen will directly affect the sense of science and technology of the vehicle interior, while high-quality display technology will bring a more comfortable and safe driving experience. Intelligent application has become an inevitable trend of the future development of vehicles, which requires more breakthroughs in display technology.
