As a much-anticipated new generation display technology, MLED (Mini/Micro LED) display is on the verge of an explosion in industrial value, and the technical bottlenecks of the industry chain are being overcome one by one.
Forward reading: Display technology has made frequent breakthroughs, and MLED is running into the early stages of industrialization
In the production and manufacturing process, Nova Nebula's "core testing equipment" has been successfully applied in batches, solving difficult mass production problems such as "MLED display consistency", "ink color consistency", "side viewing angle consistency" and "massive transfer quality inspection and repair", helping industry partners achieve standardization and large-scale manufacturing of MLED displays, and boosting the explosion of industrial value.

Difficulty 1: Display consistency problem
Eliminating the display consistency problem is of great significance to MLED mass production.
From the perspective of display quality, various factors such as materials, manufacturing processes, and craftsmanship will inevitably lead to display inconsistencies (Mura defects) in MLED displays, resulting in brightness and chromaticity deviations and unevenness, leading to display defects and impairing the user's viewing experience. Screen correction is necessary.
Compared with traditional LEDs, the size of MLED's light-emitting chips has been greatly reduced, and the pixel spacing has also been greatly reduced. With the miniaturization, the optical problems caused have become more serious. At the same time, entering the era of small and micro-pitch, MLED packaging forms have also changed. There is no mixing link, and the optical structural deviation between unit boards has increased, requiring more in-depth control and correction. Compared with LCD and OLED calibration, MLED has much higher technical requirements due to its high brightness and large color difference. For example, LCD and OLED only require 8-bit brightness correction, while LED requires at least 12-bit brightness and color correction. As the cost of MLEDs continues to decrease, more and more MLEDs will be used in commercial displays and consumer markets, and the scale of applications will grow tremendously. The traditional application method of splicing and then calibrating LEDs after leaving the factory cannot meet the needs of large-scale standardized production. MLEDs must complete online calibration in the factory to ensure display consistency and high-quality presentation. In order to solve the difficult problem in this industry, Nova has launched fully automatic Demura equipment. The device integrates a step-by-step chromaticity correction algorithm that has been developed for many years. It can quickly adjust the brightness by detecting screen uniformity and surface defects.
Chromaticity deviation (mura) can achieve the uniformity and consistency of display brightness and chromaticity expression on the production line, providing strong support for the mass production of MLEDs.

Difficulty 2: Quality inspection and repair of mass transfer
Mass transfer is the core technical prerequisite for MLED mass production. After tens of millions of dies are transferred to the circuit substrate, how to quickly light up and detect the display performance, and how to quickly repair problems after discovering them, are the key to reducing costs.
The Nova Nebula lighting inspection machine, in addition to more than 20 quality monitoring points such as conventional dead lights, dark lights, side-view lights and dark lights that plague the industry, can also conduct process level analysis through software and algorithms to accurately locate problems. Nova Nebula's fully automatic rework equipment can quickly identify abnormal display problems of MLED light-emitting chips through automatic optical detection and algorithm fusion processing. Then, through the integration and innovation of core technologies in multiple fields such as mechanics, electrical, vision, and laser, it can quickly replace abnormal lamp beads, achieve high-precision, high-quality, and high-efficiency rework, ensuring perfect repairs every time.

Difficulty point 3: Ink color consistency problem
MLED display screen requires both high permeability to increase brightness and high static visual consistency, and has extremely high requirements for ink color.
The Nova Nebula MLED ink color binning system is embedded with Nova's human vision and environment perception intelligent algorithm and ink color quantification algorithm, which effectively solves the industry problem of non-uniformity of MLED coating ink color, more accurately restores the light perception of application scenes and human visual perception, and flexibly applies various sorting solutions such as classification and sorting to reduce inventory costs and meet the quality requirements of high-end applications.

Difficulty point 4: Multi-view consistency problem
When MLED displays enter the consumer market, they need to face rigorous inspection of human vision from multiple angles.
In order to solve the display consistency problem of MLED from multiple viewing angles, Nova Nebula MLED multi-angle detection system uses multi-viewing high-precision brightness and color collection, combined with Nova's human eye perception intelligent algorithm, to optimize the display side viewing angle effect. It not only requires high-quality display from the front viewing angle, but also perfect performance from the side viewing angle.
Nova Nebula MLED core testing equipment realizes intelligent management of the entire process of MLED display lighting, testing, calibration, and repair.
On the production side, it greatly improves the yield rate and production efficiency of MLED display panels and promotes production standardization; on the application side, it brings better display effects, improves high-quality management of MLED products throughout the entire chain, and helps the MLED display industry break through production and application bottlenecks, standardizing and large-scale manufacturing of MLED displays. Nova Nebula MLED core testing equipment helps MLED display value grow.
