With the growing demand for high‐quality Organic Light Emitting Diode (OLED) display, the design of screen structure by panel manufacturers needs to consider optical performance optimization carefully, such as Wide Angle Difference (WAD). The users hope that visual color bias of the OLED display on different angles appears as small as possible, and no red visual test will be particularly accepted. The OLED display panel is usually composed of Array substrates, OLED devices, Thin Film Encapsulation (TFE) layers, touch units, Polarizers and top cover plates. The touch units contain a metal mesh, which is distributed throughout the display screen and has a great impact on the optical performance of large viewing angles. This paper aims to clarify the optical design requirements of metal mesh and provide reference for OLED optical display designers. [ABSTRACT FROM AUTHOR]

This study presents the development of ultra‐thin azo‐dye polarizers, notable for their minimal thickness (100‐200 nm) and superior optical performance, with polarization efficiency exceeding 99.9%, extinction ratios above 4000, transmittance over 45.3%, and dichoric ratio over 100. Utilizing cost‐effective solution‐processing methods, we fabricate these high‐performance polarizers and determine optimal experimental conditions for peak efficacy. Our research includes comprehensive Scanning Electron Microscopy analyses to understand the microstructural properties of these azo‐dye thin film polarizers, contributing significantly to the field of advanced display technologies.

We have developed a new polarizer system named "Light Control Polarizer (LCP)" that has a shading effect comparable to that of light control films (LCF) while significantly improving on‐axis luminance loss. The LCP exhibits a louver effect of 1.4% at a 60° polar angle and 1.1% at a ‐60° polar angle in vertical direction, with a 20% increase in on‐axis luminance over LCF and a 12% increase in contrast ratio (CR). These characteristics allow the LCP to work as an alternative to LCF providing with effective light shielding in the vertical direction without sacrificing display luminance. [ABSTRACT FROM AUTHOR]
