    • A touch screen comprising: a) a substrate; b) a first conductive layer located on the substrate; c) a flexible sheet comprising a substantially planar surface and integral compressible spacer dots formed thereon, each integral compressible spacer dot having a base closest to the substantially planar surface and a peak furthest from the substantially planar surface; and d) a second conductive layer located on the substantially planar surface of the flexible sheet, the peaks of the integral compressible spacer dots extending beyond the second conductive layer located on the substantially planar surface; wherein the first and second conductive layers are positioned towards each other and separated by the integral compressible spacer dots. Undercuts are formed around each integral compressible spacer dot, and the second conductive layer is electrically isolated from any conductive layer material deposited on the peaks of the spacer dots while depositing the conductive layer material on the substantially planar surface.

    • The present invention provides a multilayered integrated backlight illumination assembly for an LCD display comprising a substrate for providing structural and functional support to the assembly, a bottom reflector provided on the substrate and a plurality of solid state light sources provided in an opening of the bottom reflector for providing a point light source. The invention further provides a plurality of primary light films having light redirecting areas provided between the plurality of solid state light sources for redirecting and spreading the point light source to a uniform plane of light, a plurality of secondary light films having light redirecting areas provided between the plurality of solid state light sources for redirecting and spreading the point light source to a uniform plane of light and a binding means for binding the primary and secondary light films together. Further, the invention provides a top diffuser for diffusing the uniform plane of light and wherein the plurality of light films has a thickness between 0.1 mm to 1.0 mm and a bending stiffness between 50 to 1200 millinewtons.
