A sapphire wave plate resists UV and heat in outdoor HUD optics while preserving polarized image visibility, even with sunglasses.

Variable-pitch RGB micro-LED panels replace lossy RLCOS polarization optics, boosting brightness, switching speed, and power efficiency.

A lanthanum phosphate surface film on La-Ce-Si-N nitride phosphor improves light extraction and brightness without excessive phosphorus loading.

A boron- or silicon-shell phosphor balances surface area and low sodium content to raise emission intensity while preserving crystal stability.

A thin light-diffusion layer separates the LCD panel from the heat-transfer member to limit optical interference without sacrificing heat dissipation.

A light-diffusion layer separates the LCD panel and heat-transfer member to improve heat dissipation while reducing optical interference.

A solder-bonded optoceramic phosphor on a metal heat sink improves heat transfer and prevents cracking under high-power laser heating.

Laser sintering a sol-gel phosphor layer replaces glue and pressing steps, improving thermal resistance, light transmission, and conversion efficiency.

A light-diffusion layer between the LCD panel and Fresnel lens reduces interference while preserving heat dissipation in a head-up display.

A reflective optical member and sensor detect returning external light early, letting the HUD prevent display overheating and optical damage.

Quantum dot films on a projector color wheel replace yellow phosphor to widen color gamut and improve high-power image quality.

A light-diffusion layer separates the LCD panel from the heat-transfer member to limit optical interference while preserving heat dissipation.

Lenticular lenses create a 3D lit image that gives separate automotive lamps a more uniform, continuous, and distinctive appearance.

A camera-guided projector moves itself, tests image quality, and adjusts beam position and angle for hands-free projection.

A guided bracket and limit-groove mechanism lets the lens cover rotate without housing interference while closing the gap at the projection hole.

Independent pan, tilt, and roll knobs with nested movable plates improve projector alignment accuracy without a bulky, hard-to-use mount.

AI-guided camera feedback moves the projector and adjusts beam angle and height until the projected image meets target conditions.

Controlled mechanical stress flattens a convex DMD, improving phase interference uniformity and cutting scan mura in digital lithography.

Magnetic elements and secure clamping let camera accessories attach and detach quickly on hot shoes while reducing misalignment.

A lift-and-rotation mount decouples projector height and angle adjustment, keeping image size, shape, and orientation aligned to a reference point.

A rotary base with an integrated stand mount lets heavy projectors attach to tripods more easily while reducing shake and preserving balance.

A spring-biased lock lever secures a projector handle on a ceiling hook while the tubular rod conceals cables for safer installation and removal.

An elevated cart operator lets users move and adjust projectors in place for projection mapping without removal or awkward bending.

A top-mounted control panel on a wheeled projector cart lets operators align projection mapping while standing and avoid accidental inputs.

Camera-based road mapping guides projected marking layouts, cutting survey time, operator skill needs, and traffic disruption.

Optical projection replaces manual surveys and satellite-linked equipment for quick, accurate road surface marking with less setup burden.

Left-right moving parts and elevating racks let a portable projector self-adjust height and orientation for clear, level images on varied surfaces.

A two-way mirror display uses touch and presence sensing to show virtual product try-ons only when needed, reducing idle power use.

Equal-frequency beam deflection drives a light spot in a varying circular path to improve pixel spacing, scan coverage, and projection precision.

Replacing adhesive bonding with a partial welding structure helps wavelength conversion assemblies resist heat, avoid contamination, and shorten production time.

Interlocking hinge teeth and elastic pressure enable precise angle fixing with lower wear and lower replacement cost in a supported electronic apparatus.

A top-mounted rotating part drives the foot pad screw mechanism to change projector height and speed image angle adjustment.
