A light diffusion plate is configured to be assembled with a blue light source module having blue Mini LEDs to form a white light backlight module. The light diffusion plate is added with organic dyes with light-emission wavelength of 490-650 nm in order to convert the blue light into white light. The light diffusion plate is made by a foaming extrusion process and contains a plurality of micro-bubbles with a size of 60-400 μm and a weight-reduction ratio of 15-25% for improving the uniformity of white light and resolving the MURA problem. The size of micro-bubbles is controlled by reducing the temperature of at the exit end of the T-die head, such that the wavelength of the white light emitted from the light diffusion plate can be narrower to achieve the effect of wider color gamut display.
METHODS FOR MANAGING THE SCATTERING OF INCIDENT LIGHT AND ARTICLES CREATED THEREFROM
The present disclosure provides engineered surfaces that exhibit reduced specular reflection and gloss while still providing a high intensity of reflected light at multiple incident angles. The structured metal surfaces include engineered topography that increases diffuse reflection, leading to a greater intensity of light perceived at multiple viewing angles. A viewer engaging such surfaces is likely to perceive a stronger ‘white’ reflection of the incident light and an improvement, particularly in orthodontic and other oral applications, of aesthetic appearance. Methods of creating the engineered surfaces and orthodontic articles incorporating the engineered surfaces are also disclosed.
Sheer material for use in architectural coverings
The present disclosure is generally directed to a covering for architectural features, which may include windows, doorways, archways, and the like, where the covering includes a panel made from a light diffusing material. The light diffusing material is designed and engineered to allow a significant amount of light to pass through the material for providing a desired visual effect while having improved dimensional stability. The covering may contain a light diffusing material that extends along a first direction of the covering (e.g., vertically). The light diffusing material may have an openness factor of about 60% or greater and contain pillars extending in the first direction and bridges extending between the pillars. Each pillar may contain at least two yarns, and each bridge may contain at least one yarn.
SYSTEMS AND METHODS FOR IMPLEMENTING SELECTIVE ELECTROMAGNETIC ENERGY FILTERING OBJECTS AND COATINGS USING SELECTABLY TRANSMISSIVE ENERGY SCATTERING LAYERS
A system and method are provided for forming energy filter layers or shutter components, including energy scattering layers that are actively electrically switchable. The energy filters or shutter components are operable between at least a first mode in which the layers, and thus the presentation of the shutter components, appear substantially transparent when viewed from an energy/light incident side, and a second mode in which the layers, and thus the presentation of the energy filters or shutter components, appear opaque to the incident energy impinging on the energy incident side. The differing modes are selectable by electrically energizing, differentially energizing and/or de-energizing electric fields in a vicinity of the energy scattering layers. Refractive indices of transparent particles, and the transparent matrices in which the particles are fixed, are tunable according to the applied electric fields. The energy scattering layers may conceal a sensor such as a camera or photovoltaic cell.
