Since the beginning of this year, MiniLED has shown great popularity, and the industry calls 2021 the "First Year of MiniLED Commercial". It is reported that Apple may use MiniLED screens in products launched in the second half of this year; and the majority of TV manufacturers have already launched a variety of MiniLED TVs. According to the forecast of the research organization TrendForce, the global sales of MiniLED backlight TVs will reach 4.4 million units in 2021 and will exceed 35.5 million units by 2025. Skyworth also officially released Skyworth Mingli Screen MiniLED TV Q70 in February this year.
What is so extraordinary about the MiniLED that triggered the layout of major manufacturers? What are the expectations for consumers?
MiniLED More delicate picture quality performance
At present, the mainstream TV display screens are LCD displays and LED displays. Both of these screens do not emit light by themselves, and must rely on a backlight to complete the display. MiniLED, also known as sub-millimeter light-emitting diode, reduces the size of the traditional LED die to 50-200μm. Compared with ordinary LEDs, MiniLED displays have a smaller light source per unit area and higher density. For TV display screens, the number of backlight sources for traditional LCDs and LEDs is only a few dozen, while MiniLED increases this number to thousands or tens of thousands.
Combined with flip-chip COB or IMD technology, MiniLED can realize dot pitch display below 1 mm, the pixel density is higher than that of small pitch LED and can realize high grayscale display under low brightness. Using MiniLED as a backlight source in LCDs can improve contrast through area dimming and achieve HDR. The refined display effect is even comparable to OLED. For consumers, MiniLED's precise grasp of every tint of color change can present a more delicate and true TV picture and improve the perception of picture quality.
On the other hand, the flip-chip method of MiniLED does not require a lens for secondary optical design. It is not only conducive to achieving higher contrast, but also achieves the effect of ultra-thinness. For high-end consumer groups who pursue quality of life and favor home design, MiniLED TVs undoubtedly satisfy their "both in terms of mechanical image quality and exquisite appearance."
In addition, the screen using MiniLED technology also has the advantages of lower power consumption, more resistance to high and low temperatures, and longer life, and the cost performance is therefore relatively high.
In addition, MiniLED TVs also use a variety of image quality technologies to give full play to the display power of MiniLED. With the support of super quantum dot technology, the color gamut reaches 100% (NTSC_1931), and the peak screen brightness is 1500nits. With a 10bit screen, it can present more than 1.07 billion colors and restore the most true and natural colors.
The ADSDS technology and 3D LUT technology support ultra-wide viewing angles, ultra-high color expression and ultra-high-speed motion picture processing, achieving broadcast-level monitor-level color accuracy performance, and △E1.3's amazing color accuracy and high fidelity restore the shooting scene , As if the gorgeous scene in the picture is truly presented in front of you. At the same time, the Dolby Vision and HDR10 on the Q70 can provide users with breathtaking brightness, deeper dark details, expanded contrast, subtle details and expanded dimensions, which can make each scene more realistic and detailed. Bring consumers an immersive viewing experience.
