Microdisplays & light engines — A microdisplay and its projection optics form a tiny projector that sends the image into the lens. The panel type (LCoS, micro-OLED or microLED) sets brightness, color, power and size. TechInsights puts display-related parts at about half (50.8%) of the bill of materials for Meta Ray-Ban Display and its Neural Band.
Waveguides & lenses — A waveguide carries the projected image inside a thin, high-index plate and releases it toward the eye while the wearer sees through it. Reflective and diffractive waveguides are made in very different ways. Camera-and-audio AI glasses use ordinary prescription or sun lenses instead.
Processors & memory — An AR-class chip runs the camera, on-device AI, audio and wireless within a skin-contact thermal budget of roughly 1–2 W. Heavy AI runs on the phone or in the cloud, and a low-power companion chip handles always-on listening.
Cameras & eye tracking — A 12 MP world-facing camera provides photos, video and the visual input for multimodal AI, and an LED signals when it is recording. Premium AR adds inward-facing eye-tracking cameras and infrared illuminators.
Motion sensing & input — Motion sensors stabilize video and read head gestures. Touch strips, buttons, wear sensors and hinge sensors run the everyday controls, and wrist EMG bands and rings add private, hands-down input.
Speakers & microphones — Open-ear speakers sit just in front of the ear and use dual ports to limit sound leakage. An array of four to six microphones plus a bone-conduction pickup isolates the wearer’s voice for AI and calls.
Battery & charging — Tiny lithium cells, around 1 Wh or less per pair, set runtime and much of the weight balance. Power-management chips and a charging case that holds many times more energy do the rest.
Wireless & antennas — Bluetooth keeps an always-on, low-power link to the phone, and Wi-Fi moves photos and video. Antennas have to hide in a small frame right next to the head.
Frames & assembly — The frame must hide the electronics, fit many faces, pass flex circuits through its hinges and seal the device. Eyewear companies design and make frames, and contract manufacturers assemble the electronics.
Device makers & platforms — The companies that define, brand and sell smart glasses, plus the operating-system and AI platforms behind them. This group is not a physical part. Device makers are listed for their own products, not as suppliers of the parts inside.
