Different scenarios propose different performance requirements for display devices, and the corresponding mainstream display technologies selected are also different. According to usage scenarios, display devices can be divided into 2C display and 2B display.
2C display mainly refers to TVs, monitors, laptops, in-vehicle products, mobile phones, wearable products etc. LCD is the traditional technical solution mainly applied to 2C display, while it suffers from issues such as low contrast, small color gamut and limited viewing angle. With the development of material technologies, OLED technology has emerged. Compared with LCD, OLED boasts significant advantages including simpler frames, thinner overall thickness, higher brightness and contrast, larger viewing angle, wider color gamut range and lower power consumption. These strengths have quickly enabled OLED display products to dominate the consumer market.
However, OLED display products also have disadvantages such as short life. Micro LED is characterized by display technology that minimizes the LED display to a micron scale, which matches the long life and reliability of inorganic LED. This technology results in displays that feature high brightness, high contrast, wide color gamut, long service life and high reliability.
Due to these qualities, the micro LED display is considered to be a near perfect display technology. The high brightness and energy-saving capabilities favor broad application prospects of micro LED in 0.x-inch and x-inch wearable products, while Apple, as a representative, expects to apply Micro LED technology to 2C products such as the Apple Watch. On the other hand, the advantage of seamless splicing renders the Micro LED the best solution for large screen TV products above 85-inch. Currently, Sony, Samsung and some domestic display manufacturers have launched large screen consumer products based on Micro LED technology.
2B display mainly refers to outdoor and indoor large screens in the theaters, shopping malls, meeting rooms, control rooms, etc. The mainstream display technologies selected for these use scenarios include LCD splicing display, projection display and LED large screen display. The impossibility of seamless splicing for LCD and the poor brightness and contrast for projection display limit their application, while LED display characterized by high brightness, high contrast, wide color gamut, available seamless splicing and other advantages becomes the most promising display technology.
With the decrease of dot pitch, especially the development of Micro LED technology, the ultra-high definition of LED display has become a trend, and the display quality is getting more and more delicate. Consequently, the application scenarios for LED display are also expanding from the traditional engineering display to the commercial display and in-home display. It can be seen that Micro LED is highly competitive in both 2C and 2B markets because of its unique advantages. Accordingly, both traditional panel manufacturers and LED display manufacturers are actively developing this technology.
