The law of transformation of quantity into quality states that development occurs through the gradual accumulation of quantitative changes, which at a certain point lead to a sudden transition to a new quality. As known, it was formulated by Friedrich Engels as a result of the interpretation of Hegel’s logic and the philosophical works of Karl Marx.
MicroLED panels
The development of Mini LED backlit in TVs clearly demonstrates its relevance for innovation processes. Local dimming was first introduced in 2008 in Sony’s BRAVIA TVs. In 2016 Samsung first introduced full-array local dimming (FALD) technology in KS9800 (US) / KS9500 (Europe). In 2018, China’s TCL introduced the first Series 6 Roku models with mini LED backlit. Replacing traditional LEDs with miniature analogs has allowed developers to group tens of thousands of LEDs into arrays into local dimming zones with separate control. In turn, the accuracy of control in individual zones depending on the scene ensured a sharp increase in image contrast. Finally, at CES 2021, Samsung and LG presented their own versions of this technology, which were implemented in the Samsung Neo and LG QNED series. Today, it’s actively used by almost all industry leaders, including Sony, Hisense, etc.
The development of Micro LED panels follows a similar scenario. Unlike OLED panels with self-emitting organic light-emitting carbon-based diodes, MicroLED technology initially used microscopic RGB LEDs based on inorganic indium gallium nitride (InGaN). While maintaining the superb contrast of OLED technology due to perfect black, they can withstand significantly higher voltage, providing higher brightness. In this technology, every pixel has ‘its own’ micro LED. Accordingly, their physical dimensions affect the image resolution. For reference, today the smallest LEDs are made from perovskite with a characteristic pixel length of ~ 90 nm. According to Zhejiang University, nano-perovskite LEDs (nano-PeLEDs) achieve a record-high pixel density of 127,000 pixels per inch (PPI).
The fantastically expensive MicroLED panels with amazing image quality have been used mainly for advertising for many years.
Unfortunately, their six-figure price tag reliably blocks their path to the mass segment.
Samsung MicroLED
To be fair, Samsung is making great efforts to reduce the cost of this technology and is rightfully positioned as a leader in this area.
At ISE 2018 the Samsung introduced the modular large-format The Wall Professional MicroLED display in 146- or 219-inch versions.
Samsung MicroLED panels consist of 15-inches modules with magnetic mounts.
The modular design virtually eliminates their size limitation.
At CES 2019, Samsung’s line already included a more compact 75-inch 4K Micro LED TV.
The MicroLED lineup at CES 2023 included 89″ ($ 109,999), 101″ ($ 129,999), 114″ ($ 149,999) models and the ‘budget-friendly’ 76-inch MicroLED CX. It had pixel-by-pixel brightness control (great contrast due to 20-bits black-level depth), and 99.9% screen-to-body ratio (‘zero-width bezel’). This panel did not require professional installation, had a 240Hz refresh rate and the response time of 2 ns (0.000002 ms). Its announced launch price reached ‘only’ $ 80,000.
This year, the South Korean giant announced the ‘world’s first RGB Micro LED TV’ in 75″, 85″ and 98″ diagonal sizes. According to the company, it has already started test production.
RGB MicroLEDs are identical to Samsung’s MicroLED panels and in the future, they will replace them. A more complex backlight with smaller LEDs that generate red, green and blue is the only difference. In fact, they eliminate the need for a color filter, which is used in mini LED models. Unfortunately, prices are not yet known.
At the same time as the South Korean giant, Sony announced the RGB Mini LED Bravia 10, and Hisense unveiled 116UX TriChroma mini LED TV, which also uses innovative hybrid RGB Local Dimming Display technology.
AWALL MicroLED panel
However, TV industry leaders are not alone in promoting MicroLED panels. In particular, Florida-based Just Video Walls company also specializes in MicroLED video walls. It’s founded in 2022 by integrators with years of experience in the custom installation field. Company offers both pre-configured ‘Spec’ systems and ‘Custom’ with optimization for the customer. Depending on the size, resolution and technology used, the cost of their products ranges from $ 10,000 to $ 150,000 or more.
But AWALL to claim leadership in the segment of relatively affordable MicroLED panels. This company was created on the basis of AWOL Vision, which successfully developed and manufactured ultra-short throw (UST) 4K laser projectors. In particular, AWOL line includes AWOL Vision LTV-2500, 3500, 3000 Pro and 3500 Pro. The renamed AWALL is no less successful in the MicroLED segment. For example, AWALL CoB MicroLED Display wins in the AV Technology category at InfoComm 2025.
AWALL uses CoB (Chip-on-Board) technology. As known, it involves a direct mounting of unpackaged LED chips onto a circuit board. AWALL’s CoBIt provides:
– increased pixel density due to reduced size of unpackaged LED chips;
– pixel pitches of 0.9 or 1.2;
– high brightness (up to 1,200 nits), color accuracy, infinite dynamic contrast and superb native contrast up to 12,000:1 with ideal black;
– color gamut – 115% NTSC;
– ultra-high refresh rate up to 3840Hz refresh rate, which minimizes drag, blur and lag;
– 4K Ultra HD (3,840 x 2,160) resolution support;
– MultiView mode with ultra-slim modular design.
The price of AWALL MicroLED displays ranges from just $ 8,250 to $ 56,900. Sure, tens of thousands are hardly mass-market, but it’s a huge jump from the six-figure price tags.
Conclusion
Competition continues to demonstrate its effectiveness, stimulating companies to actively improve and reduce the cost of technology.
Until recently, offering magical image quality at a fabulous price, MicroLED panels were mainly used in commercial advertising or bought by owners of villas near the ocean. AWALL radically changes the situation. Today, the most affordable 75-inch version with 1.2 pixel pitch costs $ 16,600. At the same time, the modular design allows the lucky owner to buy 3 sections in the future, increasing the panel size to 81″.
To be fair, its resolution is only Full HD (1,920 x 1,080). But this aspect has a nuance. As known, resolution is necessary to ensure detail, which affects the clarity and sharpness of the picture. But they also significantly depend on the contrast, which affects object contours clarity. Simply put, low- and medium-contrast 4K images don’t look any better than high-contrast Full HD images. Given this factor, the gain in resolution of 4K TVs or projectors is noticeably compensated by the superb contrast of MicroLED panels.
