Abstract: Multilayer optical film reflective polarizers previously considered to have excessive off-axis color can provide adequate performance in an LC display in an “on-glass” configuration, laminated to a back absorbing polarizer of the display, without any light diffusing layer or air gap in such laminate. The reflective polarizer is a tentered-one-packet (TOP) multilayer film, having only one packet of microlayers, and oriented using a standard tenter such that birefringent microlayers in the film are biaxially birefringent. The thickness profile of optical repeat units (ORUs) in the microlayer packet is tailored to avoid excessive perceived color at normal and oblique angles. Color at high oblique angles in the white state of the display is reduced by positioning thicker ORUs closer to the absorbing polarizer, and by ensuring that, with regard to a boxcar average of the ORU thickness profile, the average slope from an ORU(600) to an ORU(645) does not exceed 1.

Abstract: An adjustment unit for an indirect vision system is indicated, which comprises a first and a second component connected to a support structure of an indirect vision system by as little connecting elements as possible. The interface of the adjustment unit to the support structure is to be able to withstand robust mechanical requirements in a small installation space. Due to the second component including a pressure distribution element which extends transversely to a longitudinal direction of the main connecting member, and due to the fact that pressure is applied to the pressure distribution element by the main connecting element, the forces introduced and centrally acting on the pressure distribution element and thus on the second component are equally distributed in a direction transverse to the main connecting element. Traction with the support structure therefore is no longer performed centrally, but spreaded over a transverse extension of the second component.
