Next, the editor of Liancheng will take you to see how Mini LE technology has entered the vehicle display market.

Mini LED that accelerates "getting on"

Fierce competition often sets off a wave of exploration, and the end of exploration often brings a new beginning. With the extension of the development time span of the LED display industry, the competition in the industry is also intensifying. However, the exploration and innovation in the industry But never stopped. As the development of the LED display industry gradually matures, the trend and trend can be clearly found, that is, the audience's demand for ultra-high-definition display effects has gradually become prominent. At the same time, new cutting-edge display technology has become more and more high-end product display. Competitive point, and the popular MiniLED has become more and more frequently the emerging synonym of high-end display products. Mini LED simply refers to an LED chip with a size of 50-200 microns. It is an upgraded version on the basis of traditional LED backlight and has become the best substitute for Micro LED in the development process. As we all know, in 2021, Mini LED ushered in the first year of large-scale commercialization, and global panel and electronic product terminal giants have launched products using Mini LED backlight technology.

Recently, a number of car companies announced new products equipped with Mini LED backlight technology, making the trend of MINI LED backlight technology applied to the field of vehicle display more clear. Among them, Ideal L9 mainly applies Mini LED technology to the interactive screen for safe driving with HUD head-up display design, Weilai ET7 is equipped with BOE 10.2-inch HDR Mini LED-backlit digital instrument, Cadillac LYRIQ adopts 33-inch digital instrument supplied by Innolux Ring-screen Mini LED backlight super retina screen, as well as the third-generation Roewe RX5, Feifan R7 and other cases.

In general, a number of cars equipped with Mini LED screens have been released since the beginning of this year, and Mini LED has once again been applied to new scenes and display fields. It has attracted the collective attention of LED screen enterprises.

Why can MiniLED enter the new position of in-vehicle display?

As mentioned above, Mini LED has been favored in the field of vehicle display since 2022, ushering in a huge market demand. However, why is Mini LED "connected" with the car display?

First of all, we must start with the promotion of policy reform in the auto industry. Among the several auto industry policies and regulations promulgated by the state, the biggest influence on the vehicle display screen undoubtedly comes from the drive of the new three-mode automobile policy. The "new three modernizations" of automobiles were first proposed in 2019. As the key content of the research and development of the automobile industry, the development direction of the automobile industry has been clarified as three key points: electrification, intelligence and sharing.

Then, from the perspective of strong intelligence, this concept has been rolled into the field of vehicle display from the past consumer electronics field, which has also led to the transfer of Mini LED technology, which was concentrated in the field of notebook computers, to the field of vehicle display. With the advent of in-vehicle intelligence and automation, the demand for multi-screen in-vehicles continues to increase, so the demand for overall in-vehicle screens is increasing year by year. Data shows that in 2020, the global vehicle display shipments will be 127 million pieces, and it is expected that the global vehicle display shipments will reach 207 million pieces in 2025 and 238 million pieces in 2030, equipped with 3 screens. And the number of cars above will reach about 20%.

In addition to the intelligence of the car, the key to the rising demand for in-vehicle displays is the annual hot word of the automotive industry - new energy vehicles. With the explosion of new energy vehicle sales, the continuous promotion of in-vehicle display to large-screen, multi-screen, and high-definition development gives Mini LED the opportunity to accelerate "boarding". According to CINNO Research's monthly passenger vehicle sales monitoring data in the Chinese market, the quarterly sales of new energy passenger vehicles in the Chinese market in the first three quarters of 2021 are on the rise, and the total sales of new energy passenger vehicles in the Chinese market in the first three quarters are higher than the same period in 2020. An increase of nearly 2.1 times. BYD, Tesla, Wuling Motors, ORA, and Roewe are among the top five sales in the Chinese market. Among the top ten rankings, my country's own brands account for eight, with a total market share of 74% in total sales, and domestic new energy passenger vehicles occupy an absolute position in the market. In the future, under the background of dual carbon, new energy vehicles will become the mainstream trend, and the demand for on-board displays will also increase.

Secondly, from the technical requirements of the on-board display, the importance of the on-board display as a medium for human-vehicle interaction is self-evident. In the production process of automobiles, considering the changes and uncertainties of the environment during the driving of the vehicle, as well as the possibility of the appearance of various lights, therefore, taking into account the above factors, the interior environment of the display screen has an impact on the brightness, contrast, and brightness of the screen. Resolution, field of view, optical indicators, color gamut, response speed, special shapes, etc. put forward higher requirements. The problems of uneven backlight of ordinary LEDs obviously cannot meet such high requirements. However, compared with traditional display chip particles, Mini LEDs Smaller, more delicate display effect, higher brightness, and supports precise dimming, which can well avoid the uneven problem of ordinary LED backlight. In addition, compared with the OLED screen that has steadily entered the field of vehicle display in the past, the yield rate of Mini LED backlight is higher, the cost is lower, and it has obvious advantages in mass production. In addition, some industry insiders pointed out , Generally, car display panels require a working life of more than 50,000 hours at room temperature, while the working life of currently commonly used OLED screens is usually only 30,000 hours. Due to the "burn-in" problem caused by aging, how to ensure that the display screen is synchronized with the life cycle of the car has become a desire of car manufacturers. breakthrough problem. Compared with OLED screens, Mini LEDs have strong advantages in power saving, energy saving and service life, and can well meet the needs of car manufacturers for high contrast, high brightness, durability and adaptability to curved surfaces. These are exactly the advantages of Mini LED backlighting, and also the key for Mini LEDs to accelerate the pace of “getting on the car and compete with OLED in the automotive display market in 2021. These technical advantages will undoubtedly enhance the introduction of Mini LED backlighting by car companies to a certain extent. The power of high-end monitors.

Generally speaking, Mini LED occupies an important track for innovation. With the application advantages of technology, it has ushered in a rapid development opportunity in the field of vehicle display, and is expected to play a greater market potential in the future.

The car screen shoulders the heavy responsibility of the Internet of Vehicles ecology and the deep interaction between people and vehicles. The various and colorful Mini LED displays inside and outside the car have gradually become the core interactive devices that promote the intelligence, quality and fashion of automobiles. Mini LED is an important track for new display technology, and the corresponding products are found in many fields such as automobiles. The explosion of Mini LED vehicle screen has injected stronger kinetic energy into the sea of LED displays. In the future, enterprises will continue to explore their own advantages and insist on innovation. Do not relax, will be able to open up a new situation for the LED display industry.
