OPTICAL SYSTEMS WITH LIGHT CONTROL FILMS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18558421 titled 'OPTICAL SYSTEMS WITH LIGHT CONTROL FILMS
The patent application describes an optical system that includes a display, a reflective polarizer, and a glare trap. The glare trap consists of slats with specific dimensions and spacing, creating elongated slots filled with air. The reflective polarizer has high optical reflectance and transmittance for different polarization states, while the glare trap allows controlled transmission and reflection of light.
- The optical system includes a display, a reflective polarizer, and a glare trap.

Original Abstract Submitted
An optical system includes a display, a reflective polarizer, and a glare trap. The glare trap includes a plurality of slats having a length L and a width W, L/W≥10. The slats form a plurality of elongated slots therebetween substantially filled with air. The reflective polarizer has an average optical reflectance of at least 40% for a first polarization state and an average optical transmittance of at least 40% for an orthogonal second polarization state. For each of the first and second polarization states, the glare trap has an average specular optical transmittance of between about 20% to about 80% and an average total optical reflectance of less than about 20%. For at least one wavelength in the visible wavelength range, an optical transmittance of the glare trap includes a first transmittance peak at a first peak angle with a corresponding FWHIM of less than about 30 degrees.
