• The world’s first demonstration of a direct retinal projection display for smart glasses using a meta-optic mirror.
• A natural-looking appearance suitable for everyday use, enabled by an ultrathin, transparent mirror that can be embedded in a lens.
• Future realization of full-color capability to contribute to the widespread adoption of smart glasses.

TDK Corporation (TSE:6762) has successfully demonstrated, for the first time in the world, a direct retinal projection (DRP) display for smart glasses using a meta-optic mirror. The flat mirror uses nanoscale reflectors, measures just 150 nm thick and can be embedded directly into a lens. With a visible-light transmittance of approximately 80 percent, it enables smart glasses with transparency equivalent to that of ordinary eyeglass lenses, giving them a natural appearance suitable for everyday use. TDK will exhibit a prototype at CEATEC 2026,  beginning on October 13, 2026, and at electronica, November 10-13, 2026.

TDK has established technologies for an ultra-compact full-color laser module (FCLM), one of the smallest of its kind in the world, and a visible-light full-color laser control device capable of achieving 4K resolution. The company has also been developing the key devices required for DRP in smart glasses. Conventional DRP systems used a curved mirror mounted in front of the user’s eye to project images onto the retina, making it difficult to achieve smart glasses with a natural appearance. By arranging unique nanoscale reflectors on a plane and creating a structure that changes the angle of light reflection depending on the position of the mirror, it is possible to reflect laser light incident from various angles at the reflection angle necessary for DRP. Therefore, it is possible to replace conventional curved mirrors.

Furthermore, the DRP smart glasses prevent images from being visible to people facing the wearer (image leakage). This provides a natural look and addresses privacy concerns since others cannot see the projected content.

Conventional waveguide displays have complex structures and can be costly to manufacture. The meta-optic mirror, however, can be manufactured using processes comparable to those used for semiconductors, opening the way to cost-competitive mass production. The current meta-optic mirror supports monochrome operation. TDK aims to demonstrate full-color operation and achieve mass production within the next few years.

TDK has entered into a business cooperation agreement with QD Laser, Inc. (TSE:6613, hereinafter “QD Laser”). By combining QD Laser’s proprietary retinal projection technology and patent portfolio with TDK’s FCLM, visible-light full-color laser control devices, meta-optic mirrors, and other technologies, TDK is accelerating the development of next-generation RGB light source modules and optical engines for smart glasses. TDK will contribute to the transformation of smart glasses, an application expected to grow within the AI ecosystem on which TDK is focusing, and their widespread adoption in society. 

TDK Corporation (TSE: 6762) presents the B3272*A/G/T series of DC-link film capacitors. These are qualified for continuous operation at case temperatures of up to +135 °C, with no derating required up to +105 °C. These components feature an EPN dielectric. This blend of polypropylene (PP) and cyclic olefin copolymer (COC) has already been proven in TDK’s ModCap UHP power capacitors. This allows DC-link designs for demanding automotive and industrial power electronics applications to have greater thermal headroom.

On-board charging units, xEV traction inverters, DC-DC converters, industrial drives, and high-end power supplies must operate reliably even as power density increases, in confined spaces, and at higher ambient temperatures. These constraints subject passive components to growing thermal and electrical stress. The B3272*A/G/T series is designed to meet the demands of such applications.

The series spans rated DC voltages from 800 to 1200 V and rated capacitance values from 1.0 to 60 µF, with three lead spacings: 27.5 mm, 37.5 mm, and 52.5 mm (B32728G, 4-pin). The 4-pin G-types support low-inductance busbar interfaces and help reduce parasitic loop area in fast-switching inverter stages, while the low-profile T variant addresses height-constrained layouts in compact automotive and industrial assemblies.

The flame-retardant plastic case and epoxy resin sealing both comply with UL 94 V-0. The series is AEC-Q200E qualified and RoHS-compatible, supporting global use in automotive and industrial converters where thermal headroom, reliability, and compact integration must be optimized together.

For the B3272*A/G/T series, TDK provides various SPICE model libraries and the web-based Capacitor Life And Rating Application (CLARA) tool.

TDK Corporation (TSE:6762) has expanded its B43645, B43657, B43658, B43659, B43660, and B43661 series of ultra-compact snap-in aluminum electrolytic capacitors to meet the specific needs of advanced AI server power supply units (PSUs) and high-performance SMPS applications. Additionally, the rated DC voltages were raised to 500 V. With diameters ranging from just 22 mm to 35 mm and lengths between 25 mm and 100 mm, these capacitors deliver high voltage capability in an exceptionally compact form factor. For high-performance power supplies, this translates to higher power densities, improved reliability, and greater design flexibility—critical for supporting the continuous, high-load operation typical in AI data centers. This enables smaller, more efficient systems without compromising electrical or thermal performance. 

These extended-voltage series cover capacitances from 80 µF to 2060 µF, handle high ripple currents up to 5.39 A, and deliver a service life of up to 5,000 h at +105 °C. Their ultra-compact CV design minimizes footprint, while robust aluminum-can construction with PET sleeve, secure snap-in pins, and integrated pressure relief ensures durability. All types are RoHS-compliant and vibration-tested per IEC 60068-2-6. 

The web-based AlCap Tool quickly and easily calculates accurate lifetime under application-specific conditions. 

• New 100 V SMD component with X7R characteristics has a capacitance of 10 μF in the 3225 format 

• Offering low resistance and soft termination for automotive (AEC-Q200) and general applications 

• Contributes to higher reliability, reduction of component count, and miniaturization 

TDK Corporation (TSE:6762) announced today that it has expanded its CN series of low-resistance soft-termination SMD MLCCs. This 100-V component with X7R characteristics achieves an industry-leading* rated capacitance of 10 μF in the 3225 format (3.2 x 2.5 x 2.5 mm – L x W x T). Mass production of these new components began in September 2026. The CN series is TDK’s proprietary product line, equivalent to the regular product line in terms of terminal resistance, due to the optimization of its resin electrode structure.  

In recent years, there has been an increase in the use of 48 V applications in AI servers, humanoid robots, xEVs, and various industrial equipment within the AI ecosystem. The goal has been to reduce power loss and the weight of wire harnesses. Consequently, 100 V-rated MLCCs that are used in power lines must have even larger capacitance. On the other hand, in soft-termination products, which are increasingly being adopted as a measure against MLCC cracks caused by external stress, the increased ESR (equivalent series resistance) resulting from the addition of the resin layer has been an issue. 

This led TDK to develop the CN series with optimized resin electrode structures. Thanks to the optimized material selection and product design, these components achieve twice the capacitance of TDK’s conventional capacitors of the same size while significantly reducing ESR. These new products make it possible to halve the number of MLCCs used and the mounting area. This helps reduce component count and miniaturization of sets and is also effective in enhancing reliability in 48-V power lines, e.g., in AI servers. TDK will continue to expand its product line to meet the diverse needs of its customers.
