“…The reflectance of metallic wire grid is a very interesting and vexing problem. But in the past years, the research of grid line optical property mainly concentrated on the experimental study of its reflectance and polarized property [1][2][3][4][5][6]. For example, H. Blancher studied an experimental method to determine the wave-change of phase and its reflection on a grid line [7].…”

In this paper we present a model to investigate the reflectance on a metallic grid line. Based on the free path theory in the basic physics, we derived a corrected expression for calculating the free path in a metallic grid line. Then, we obtain a formula for describing the dependence of optical reflectance on its size. The theoretical results show that the size of grid line has a relatively large effect on its reflectance when the width and thickness of grid line are below 300nm. The reflectance will reach the value of bulk material when the width and thickness of grid line are over 800nm.

“…Techniques such as interference lithography, 41,42) nanoimprint lithography, 43) and electron beam lithography 44) have been used to shape Al into a lattice. In this study, we created a nanostripe electrode following the studies of Takada et al 45) and Suzuki et al 46,47) A thin film of Al was deposited on a glass substrate using the sputtering method, and the nanostripe electrode was formed by reactive ion etching.…”

In this paper, we report on the luminescence (emission) characteristics of a laminated dispersion-type inorganic electroluminescent (EL) device with a nanostripe electrode made of thin Al film, instead of a conventional indium–tin oxide (ITO) transparent electrode, on the emission side of the device. The transmittance of the Al nanostripe electrode, with 60-nm line-and-space widths, was 45%. We compared an inorganic EL device positioned between two thin films of Al and the inorganic EL device with the Al nanostripe electrode using electric field simulations and actual experiments. We were able to apply the same electric field intensity to the phosphor layer in the conventional structure and to the new structure. Therefore, with an Al nanostripe electrode on one side of the EL device, it is possible to fabricate an ITO-free display.

Absorptive polarizers are pivotal components for realizing a low ambient reflection in liquid crystal displays (LCDs) and organic light-emitting diodes (OLEDs). Different types of absorptive polarizers have been proposed. Nevertheless, the realization of compact and efficient absorptive polarizers remains challenging. Wire grid polarizers (WGPs) are a promising solution because of their high durability and relatively thin thickness. In this paper, two structures of absorptive-WGPs have been proposed and optimized at the target wavelength of 532 nm: one is based on a patterned F e 2 O 3 / A l bi-layer on top of a S i O 2 substrate, and the second one builds on the first one by depositing a S i O 2 layer in the gaps of Al. The optimal solutions exhibit a reflectance less than 5%, a transmittance over 45%, and an extinction ratio over 40 dB. To evaluate the manufacturing feasibility, their sensitivity to the wire’s dimensional parameters is investigated. Their great spectral performance and large acceptance angles demonstrate that such polarizers have the potential to significantly promote the development of current display technologies.
