Micro LED displays will increase to 15.5 million units in 2026
Recently, IHS Markit said that due to a sharp decline in manufacturing costs, the global market for Micro LED displays is expected to grow to 15.5 million units in 2026.
The data and information services company’s report, titled the IHS Markit Micro LED Display Technology and Market Report, states
Micro LED shipments in 2019 and 2020 are expected to total less than 1,000 units. However, forecasts for significant declines in manufacturing costs over the next few years suggest that Micro LED pricing will fall, with TVs and AR systems set to benefit. “The manufacturing process of Micro LED will allow suppliers to reduce production costs over time. Once this process matures, Micro LED sales will start to rise.
Micro LED is expected to reach the maturity threshold in 2024, and the manufacturing cost of 75-inch TV monitors is expected to drop to one-fifth of current costs. Although user acceptance has increased, micro-LED shipments will only account for 0.4% of the global flat panel display market in 2026. However, shipments of close to 16 million units will lay the foundation for micro-LED to enter the mass market in the future. (Source: inavate)
LED mass transfer equipment with 3 times efficiency
On June 16, South Korean equipment manufacturer QMC announced that the company has developed equipment that can increase the efficiency of Micro LED mass transfer by 3 times - the MDT series. QMC said it is already conducting product testing with domestic and foreign Micro LED manufacturers.

The equipment developed by QMC can transfer 60,000 chips per hour. Mainly, the pick-up process in the traditional chip pick-up and place steps is eliminated, and the chips can be directly moved and displayed to the designated location. Adopting RPA technology (Reactive Pressure Actuation) that has been developed exclusively over several years. This technology is like sewing machine threads, which can quickly arrange the chips to the designated position. The efficiency and speed of operations have been increased by 3 times, and the position accuracy has also been improved. Transfer and secure the chip with appropriate pressure and positioning.
QMC representative Yoo Byeongso said: The mass transfer speed has been increased to 65,000 pieces per hour, and the precision has also been increased from the common 25 to 10 levels. It is generally difficult for mass transfer equipment in mass production to handle sizes below 100, but the new equipment developed by the company can carry out mass transfer while ensuring that it is suitable for the size of Micro LED.

JBD demonstrates 2.5 micron pitch matrix Micro LED
AMuLED display panels are manufactured by JBD’s proprietary hybrid integration technology
Hong Kong-based Jade Bird Display Ltd (JBD) recently demonstrated a 2.5 micron pixel pitch active matrix micro LED (AMuLED) display panel, which the company believes will break the micro LED industry record.
The 2.5 micron AMuLED display panels are manufactured using JBD’s proprietary hybrid integration technology. In the hybrid integration process, ultrathin InGaN (for blue and green) and AlInGaP (for red) epitaxial layers are first grown in MOCVD on their substrates (such as sapphire and GaAs). The complete epitaxial layer is then separated from the substrate wafer and bonded to the CMOS wafer at temperatures below 350°C. This wafer-level epitaxial transfer eliminates the need for alignment bonding and significantly improves pixel yield, uniformity and manufacturing yield.
After the epitaxial layer is transferred, standard photolithography and etching steps are performed to convert the thin epitaxial layer wafer into an emitter array on the CMOS backplane wafer. Electrical contacts are then made through a cycle of photolithography, passivation and metallization.
Optical elements such as microlenses and reflector arrays are ultimately fabricated on the emitter on a single wafer scale before dicing the wafer into chips. To achieve the required light collimation, the emitter mesa diameter is designed to be approximately one-third of the pixel pitch. Therefore, for a 2.5 μm pixel pitch, the emitter mesa diameter is less than 1 μm. (Source: compoundsemiconductor)
Samsung’s customized modular Micro LED display was officially released
Recently, at the InfoComm exhibition in the United States, Samsung exhibited a variety of TV products. The most noteworthy one is the newly launched The Wall Luxury series at the exhibition, a customized modular Micro LED display. According to reports, "The Wall Luxury" Micro LED display can be customized according to any size and screen aspect ratio, with screen sizes ranging from 73 inches (2K) to 292 inches (8K).
According to Samsung, Micro LED has a lifespan of 100,000 hours and a peak brightness of 2,000 nits. Less than 30mm thick, the bezel-less design and customizable frame allow the display to blend seamlessly into its surroundings. In terms of image quality technology, The Wall Luxury products are also equipped with the AI image quality engine Quantum Processor Flex. Quantum Processor Flex is a machine learning-based image quality engine that automatically calibrates original low-resolution video sources based on modular screen resolutions to provide optimized image quality.
Thanks to the smaller size of the Micro LED module, The Wall Luxury product has better ultra-narrow bezel performance. When combined with Samsung's characteristic ambient screen mode, it can display various works of art and customizable pictures, turning it into a dynamically displayed art gallery.
With many new features, the future development of Micro LED is generally optimistic. In addition to Samsung, other companies such as Apple, LG and Sony are also developing Micro LED screens. It is reported that in terms of Micro LED layout, Samsung has actively opened up the supply links of the Micro LED upstream and downstream industry chains, including signing a strategic cooperation with Sanan Optoelectronics, a leading brand in the Chinese LED industry, to ensure stable supply of Micro LED chips. At the same time, it also invested and controlled PlayNitride, a Taiwanese Micro LED panel manufacturer. It is understood that the company has mass transfer technology, including Micro LED chip production technology, and defective chip detection and repair technology. Samsung has carefully planned its strategy in Micro LED display.
Yimeixinguang’s 4K Micro LED display is ready for mass production
Recently, Beijing Yimeixinguang exhibited a 139-inch 4K Micro LED display at the Guangya Exhibition.
The display is assembled from 576 96mm×96mm Micro LED display modules with a pixel pitch of 0.8mm. Yimeixinguang and South Korea's Lumens jointly developed Micro LED display technology with pixel pitches from 2.0mm to 0.55mm. The Micro LED display IconiView displayed this time is based on Flip-Chip-on-Module (COM) technology and an LED chip that combines dot matrix drive and image processing algorithms, reaching 1,570,900 pixels/㎡. Its contrast ratio exceeds 3000:1 and its brightness reaches 2000nit. Yimeixinguang pointed out that the product has completed certification and can achieve mass production.
