High-precision 3D sensing developer CyberOptics Corporation announced its financial results for Q2 2020, with $16 million in sales and a net profit of $1.6 million. The company says it is enjoying a "first-mover status" in the microLED inspection and metrology market.

CyberOptics says that at the end of the quarter it received a $2.5 million order for SQ3000 Multi-Function systems for micro LED applications, and additional micro LED-related orders are anticipated during the second half of 2020.

MicroLED, believed by many to be the next generation of display technology, has been pursued by players of LED, display, OEM, materials and so on. Differentiated from LCD and OLED, microLED is considered to be the only display technology that has no size limitation. What are the potential applications? What are the hypes and realities? These are questions addressed in the brand-new IDTechEx report, “Micro-LED Displays 2020-2030: Technology, Commercialization, Opportunity, Market and Players”.

Various Motivations Are Driving the Progress of MicroLED Displays

Samsung Display has announced it is ending the LCD business and will focus on its QD LCD & OLED businesses. LG Display has halted its domestic production of LCD panels. Korean vendors tend to reduce their LCD panel production and shift to QLED & OLED. In addition, Panasonic and JDI are also getting out of the LCD business. AUO, Innolux and a few other Taiwanese companies are slowing down investment in LCD or OLED. As a comparison, LCD manufacturing is shifting to mainland China due to cost competence, new line production efficiency and industry chain support.

Israel-based display characterization and inspection equipment maker InZiv has recently announced the shipment of a high-resolution pixel characterization tool to an undisclosed Tier-1 consumer electronics company.

InZiv's tool offers MicroLED defect detection on the wafer and pixel level with unprecedented sub-micron resolutions. Measuring luminescence, spectral wavelengths and 3D structure at the highest resolutions, the equipment enables the identification and the source of defects, accelerating product time to market.

High-precision 3D sensing developer CyberOptics Corporation announced that it has received a $1.2 million order for its SQ3000 Multi-Function systems for Automated Optical Inspection (AOI), Solder Paste Inspection (SPI) and Coordinate Measurements (CMM), to be used in the scale-up of micro-LED technologies.

CyberOptics says it expects more micro-LED equipment orders later in 2020. In August 2019 the company announced a $1.3 million order for a system SQ3000 system.

Canada-based VueReal is a startup company that develop Micro-LED based microdisplays. The company's Continuous Pixelation micro-printing technology offers high density displays, high production yields and a simple design.

VueReal's founder and CEO, Reza Chaji, was kind enough to answer a few questions we had on the company's technology and business.

Reza, thank you for your time. Can you explain VueReal's micro-printing process and technology?

VueReal’s solution is a true printing process where you do not need to pick LEDs for each transfer. It is based on a cartridge design by VueReal that releases the LEDs selectively into the substrate.

Introduction

Emissive OLED, microLED (uLED), and miniLED are emerging as the next wave of technology in the display market. This is exciting because these displays promise improved display performance and visual appearance with greater efficiency than other display technologies, thanks to their individually emitting pixel elements. Both OLEDs and microLEDs have superior contrast ratios and sharper images with deeper blacks and more vibrant colors than traditional LCDs. These emissive displays require no backlight, resulting in thinner, lighter-weight displays that use less electricity. OLEDs also bring a dramatic boost in responsiveness, about 1,000 times faster than existing technologies, virtually eliminating blur on fast-moving and 3D video. MicroLEDs match OLED technology for response time and view-angle performance, but exceed OLED in brightness and ruggedness, with even lower power consumption.

As manufacturers work to launch commercially viable emissive display products, high costs due to material prices and manufacturing yield issues have hindered widespread technology adoption most dramatically in large-format implementations, as they drive up end-customer prices. The smartphone market has been the most successful segment for OLED technology to date and will likely be the catalyst that drives long-term adoption of OLEDs and microLEDs for other applications. Display Supply Chain Consultants (DSCC) cites smartphones as the dominant OLED market, accounting for around 91% of units per year with revenue share around 79% by 2022². Yole Developpement (Yole) projects a similar trend for microLEDs, with a longer ramp up period, and a market reaching up to 330 million units by 2025³. With this type of growth in demand, improvements in manufacturing efficiency are needed.

High-precision 3D sensing developer CyberOptics Corporation announced that it has received a $1.3 million order for its Multi-Reflection Suppression (MRS)-enabled SQ3000 Multi-Function systems for Automated Optical Inspection (AOI), Solder Paste Inspection (SPI) and Coordinate Measurements (CMM).

CyberOptics says that the systems, which will ship in Q2 2020, will be used for the scale-up of Micro LED device production.

UK-based Optovate recently announced that it has developed a parallel aligned Micro-LED transfer process. Today the company revealed more details about its Micro-LED technology.

Optovate p-LLO transfer process

Since 2008, Optovate develops catadioptric micro-optic arrays to enhance the benefits of micro-LED, mini-LED and OLED displays. The company also developed a patterned laser lift-off (p-LLO) micro-LED transfer process.

Taiwan-based Micro-LED developer Mikro Mesa's chariman, Chen Li-yi, estimates that it will be difficult for micro-LEDs to compete with OLED displays in the small/medium display market - but the opportunity for large area displays is more promising.

According to Chen, 55" micro-LED panels will be competitive in cost with LCDs, and if companies manage to achieve yields of over 80%, a 55-inch micro-LED will be cheaper by around 30% from an equivalent high-end LCD.
