A passive electrical article including a dielectric layer having a nonwoven material.

Passive electrical article

An electrolyte membrane having a proton conducting polymer reinforced with a nanofiber mat made from a nanofiber comprising a fiber material selected from polymers and polymer blends; wherein the fiber material has a fiber material proton conductivity; wherein the proton conducting polymer has a proton conducting polymer conductivity; and wherein the fiber material proton conductivity is less than the proton conducting polymer conductivity, and methods of making. In some embodiments, the nanofiber further comprises a proton conducting polymer.

Reinforced electrolyte membrane

In a liquid crystal display (LCD), for example an LCD monitor or an LCD-TV, a number of light management films, including a diffuser layer, lie between the light source and the LCD panel to provide bright, uniform illumination. In some embodiments, the diffuser layer is attached to the lower side of the LCD panel. Some, or all, of the light management layers may be attached together as a laminated stack of films. In some embodiments, the diffuser layer is formed with a recessed region on one side and another optical film positioned within the recessed region.

Liquid crystal displays with laminated diffuser plates

Optical film laminates of birefringent polyester films and adhesive are disclosed. The laminates have a thickness of at least 10 mils (0.25 mm). The laminates of the invention are useful in displays having a diagonal of 37 in (94 cm) or greater.

Optical film laminates

In a directly-illuminated liquid crystal display (LCD), for example an LCD monitor or an LCD-TV, a number of light management films, including a diffuser layer, lie between the light source and the LCD panel to provide bright, uniform illumination. The diffuser layer is attached to a substrate which is separate from the light source and the LCD panel, or may be attached to either the LCD panel or, when using a two dimensional light source, to the light source. The other light management layers may also be attached to the separate substrate or to the LCD panel or two-dimensional light source. High levels of illumination uniformity at the LCD may be achieved with a uniform (non-patterned) diffuser, even with relatively low levels of diffusion, when the diffuser is used with a brightness enhancing layer.
