According to a new report from Korea, however, not only that Samsung cannot really find customers for its TVs (which isn't a surprise given the price), the TVs are also suffering from high defect rates - even in units shown in retail or showcase events. The report suggests that the high level of defects in the TVs have caused Samsung Electronics to decide to currently not expand its microLED TV lineup, and has postponed the release of 80-inch and 90-inch products indefinitely.

MICLEDI and QustomDot to jointly develop color microLED microdisplays with QD color conversion

QustomDot and MICLEDI announced a joint  development program to develop color microLED microdisplays using QustomDot's color conversion technology. The companies will demonstrate a microdisplay that offers a new architecture tailored for high-efficiency color conversion using stable RoHS-compliant QD materials. The displays will be produced using a high-throughput QD transfer and patterning techniques on micron-sized pixels.

QustomDot developed a patented method to produce high-quality and stable QD materials suitable for microLEDs. MICLEDI is producing its microdisplays on 300 mm wafers, and the company developed a new pixel architecture that has been optimized for high-aperture (>60% aperture at a 3μm pixel pitch) which the company says is a key requisite to achieve a high brightness with quantum dots.

Green GaN microLED developer Kubos Semiconductors raises $600,000

UK-based Kubos Semiconductors raised $605,000 to launch its cubic-GaN LED technology into new markets, such as microLED displays.

Kubos says that its unique cubic-GaN technology can increase light output (and efficiency) of green LEDs. Kubos operates in a fabless model and says that its technology is fully compatible with standard LED development process on large wafers, offering lower cost volume production. Kubos is also looking to use the technology to produce red GaN LEDs.

Epistar to invest $122 million USD to build 150 mm microLED epiwafer capacity

According to Ennostar, the company intends to invest around $122 million USD in its Epistar subsidiary, with an aim to setup a production capacity of 150mm microLED epitaxial wafers. The investment will be performed in several stages.

Ennostar also updates that Epistar has completed its mini LED chip production capacity, but the demand for such chips is lower than expected, and so the company's mini LED production utilization is not at 100%.

Anycubic launches a portable 3D printer based on JBD's microLED UVA display

3D printer producer Anycubic announced a new consumer-grade pocket-sized 3D Printer, that is based on a small UVA microLED display, produced by JBD.

The display is JBD's standard 0.13" VGA display, but one that emits UVA emission. JBD also developed a custom projector for this new application. The extremely small, yet bright, display module, enabled Anycubic to design an extremely small printer (which is about the size of a 550 cl beverage can). The printer will be able to print details as small as 10 µm due to the high pixel density (>6000PPI) of the microLED display. The energy consumption during operation is only 6W.
