Recently, news of the development of new technologies and new equipment in the Micro LED market has been continuously coming. For example, the University of Texas has developed foldable, bendable, and cutable Micro LEDs; Favite has developed AOI equipment for Micro LED production.
The foldable, bendable and cuttable Micro LED was born
According to reports, the Micro LED developed based on the new method can be transferred to the rubber substrate. From the verification results, even if the substrate has obvious wrinkles, it will not affect the normal operation of the Micro LED. In addition, the researchers say that they can also cut the Micro LED products developed in half and continue to use them. The flexible LED device was developed using a technique called Remote Epitaxy, which allows researchers to grow a thin layer of LED chips on the surface of a sapphire wafer or substrate.Typically, such LED chips are left on the wafer. However, to make such LED devices "Detachable", the researchers added a non-stick layer to the substrate, a mechanism similar to using parchment paper to protect a baking sheet. With such a non-stick layer, the researchers could easily remove the LED chips. In fact, the functional layer the researchers added is made of a single-atom, two-dimensional carbon material called graphene, which prevents the new layer of LED chips from sticking back to the original wafer.
To verify the flexibility of this Micro LED device, the researchers tested it in the lab by adhering the LED device to a substrate with a curved outer surface and twisting it during subsequent testing, Processing operations such as bending and wrinkling. In addition, they also cut the Micro LED device. The results showed that the bending and cutting tests did not affect the luminous quality and electrical properties of the LEDs. According to reports, this flexible curved Micro LED device has a variety of potential applications, including flexible lighting and display, smart clothing and wearable biomedical devices. From a manufacturing point of view, this manufacturing technique also provides another potential alternative for designers, after all, it allows designers to remove LED devices
without destroying the LED underside wafer substrate, a potential The advantage is that the wafer can be reused. In addition, the researchers say they have applied the fabrication technique to other types of materials.
Favite develops new AOI equipment for Micro LED production
On August 16, AOI equipment maker Favite said at an investor conference that it has developed AOI equipment for the production of Micro LED chips and panels, and that shipments of such equipment have begun by the end of 2021.Favite pointed out that although the industry standard for Micro LED has not yet been formulated and the development of Micro LED faces many technical challenges, large suppliers and supply chain manufacturers have been keen on the research and development of Micro LED, adding that technical difficulties will slow down the Micro LED supply chain development of.
Favite said that in terms of display performance, Micro LED panels have the characteristics of high brightness, high color saturation, high resolution, low power consumption and short response time. Currently, Micro LED panels are mainly used in wearable and AR/VR devices. Previously, the market research agency DSCC released a forecast report showing that by 2025, mainland manufacturers will account for more than 70% of the global display panel production capacity, while the share of Taiwanese manufacturers will remain roughly unchanged, while the share of southern manufacturers will remain basically unchanged. Companies in South Korea and Japan will shrink.
It is reported that in addition to display panels, Favite has also developed AOI equipment for IC advanced packaging, power management IC and IC carrier production.
Jingcai: Micro LED related AI/AOI equipment has been shipped
Jingcai Technology Co., Ltd. recently held a law meeting. Wang Ziyue, deputy general manager and spokesman, said that it has received a large order for equipment purchases for new production capacity construction of leading panel factories. Flexible LED display. LED-related AI/AOI equipment has been shipped, and is expected to become a weapon against economic turbulence.
It is reported that Crystal Color Technology benefited from the large equipment purchase orders for the new production capacity of the leading panel factories, and the injection of orders for the optimization of the old production line process. .12 yuan, which has exceeded the total profit for the whole year of last year. The company currently occupies more than 50% of the market share of AOI inspection equipment in the front panel of the panel, and is sprinting for AI automatic optical inspection equipment (AOI) to effectively increase profit margins.
Wang Ziyue said that the increase in the penetration rate of large-size TVs has brought about greater demand and investment for the establishment of panel factories in the next generation. In addition, the demand for notebooks, flat panels and large-scale displays, as well as the increase in the demand for automotive panels, has become the general trend of intelligent automobiles. Trends are all in Crystal Color's favor.
