LC-Tec Displays AB is a Swedish technology company that develops and manufactures optical components based on proprietary liquid crystal (LC) technology. Founded in 1988 in Borlänge, Sweden, the company is the operating subsidiary of LC-Tec Holding AB, which is publicly traded on the Swedish stock exchange.

LC-Tec maintains advanced electro-optical research laboratories and automated manufacturing facilities at its Borlänge headquarters, complemented by high-volume production partnerships. The company specializes in modulating light properties—such as intensity, phase, and polarization state—electronically without moving mechanical parts, supplying customers across cinematography, stereoscopic 3D projection, smart eyewear, and scientific research worldwide.

Offer

LC-Tec offers a comprehensive portfolio of standard and custom liquid crystal optical devices and controllers:

  • Electronic Variable ND Filters (PolarView-eND): Electronically controllable neutral density filters that allow continuous, smooth light transmission adjustment without color shift or mechanical motion.
  • Fast Optical Shutters: High-speed LC light valves designed for sub-millisecond light blockage and transmission modulation, operating silent and vibration-free.
  • Fast Polarization Modulators (PolarSpeed): Polarization rotation devices optimized for stereoscopic 3D projection, polarization imaging, and industrial machine vision.
  • Variable Optical Retarders: Voltage-controlled wave plates delivering precision phase retardation and polarization state manipulation across visible and NIR wavelengths.
  • Electronic Variable Diffusion (EVD): Tunable optical diffusion filters providing variable beam shaping and image softening directly within camera optical trains.
  • Dedicated Electronics: Specialized miniature digital drive controllers delivering optimized waveform generation and thermal compensation.
