摘要： Certain aspects of the present disclosure provide techniques for a front panel for a video display system. According to disclosed embodiments, a substrate is fabricated to incorporate materials having desired functional properties, such as the blocking of ultraviolet visible (UVV) laser light, and near infrared light, into the substrate material. After extrusion of the substrate with desired functional properties, an anti-glare hardcoat may be spray-coated to the front and back of the front panel to provide anti-glare as well as anti-stiction properties.

摘要： An optical filter includes a transmission portion transmitting light and an absorption portion absorbing light between a plane of incidence and a plane of emission, and the volume of the transmission portion is larger than the volume of the absorption portion. For the optical filter, when the transmission spectrum S0 of light incident at an incidence angle of 0° and the transmission spectrum S60 of light incident at an incidence angle of 60° are superimposed, the transmittance (%) at an incidence angle of 60° is lower than the transmittance (%) at an incidence angle of 0° by 15% or more for a first wavelength band, and the difference between the transmittance (%) at an incidence angle of 60° and the transmittance (%) at an incidence angle of 0° is 10% or less for a second wavelength band.

摘要： There is described a multilayer optical thin film structure comprising multiple optically absorbing layers and multiple optically non-absorbing layers. The optically absorbing layers and the optically non-absorbing layers are configured such that light incident on the structure is reflected with a red colour at a first angle, and light incident on the structure is reflected with a yellow colour at a second angle. There is also described an item having applied thereto such a multilayer structure.

摘要： A decorative sheet has a pattern formed with an interference pigment and is more versatile with reduced coloration specific to the interference pigment. A patterned layer has a pattern formed with an interference pigment to produce a color by interference of reflected light reflected after being incident as incident light on a front surface of the patterned layer. A front color-adjustment layer covers the front surface of the patterned layer and transmits the incident light, incident light, and the reflected light. A base film supports the patterned layer and the front color-adjustment layer. The front color-adjustment layer contains particles of a front absorbing pigment dispersed uniformly across the front color-adjustment layer. The front color-adjustment layer with the front absorbing pigment reduces a spectral component in a predetermined wavelength range of the incident light and the reflected light transmitted through the front color-adjustment layer.

摘要： Color-selective waveguides, methods for fabricating color-selective waveguides, and augmented reality (AR)/mixed reality (MR) applications including color-selective waveguides are described. The color-selective waveguides can advantageously reduce or block stray light entering a waveguide (e.g., red, green, or blue waveguide), thereby reducing or eliminating back-reflection or back-scattering into the eyepiece.
