34.2: Viewing‐Angle Compensation of IPS and Circularly Polarized VA‐LCDs Using a Novel Ultra‐Thin Homeotropically Aligned Liquid‐Crystalline Polymer Film

Abstract

We have developed a novel ultra-thin homeotropically aligned liquid crystalline polymer (LCP) film called "NV film". NV film allows In-Plane-Switching (IPS) and Circularly-Polarized Vertical-Alignment (CPVA) LCDs to have excellent viewing angle performance with only a slight increase in the total thickness just by attaching the film to the panel.

Structure and application of polarizer film for thin-film-transistor liquid crystal displays

“…(+) C-plate, (À) A plate, biaxial compensation film or combination of multicompensation film may be used [48][49][50][51][52][53]. For MVA mode TFT-LCDs, negative LCs are aligned vertical to the substrate, thereby (+) Aplate, (À) C-plate, biaxial compensation film or combination of multi-compensation film may be adopted [54][55][56][57][58][59][60]. Different compensation films are used depending on sheet-to-sheet or rollto-roll manufacturing process and display performances.…”

34‐3: High Contrast Research of 4K ADS TV Technology

“…Thin film transistor liquid crystal display (TFT-LCD) is still the mainstream display technology because of its high yield, good size compatibility, long working time and low production cost [1]. TFT-LCD display modes mainly include Twisted Nematic (TN), Vertical Alignment (VA), In-Plane Switching (IPS) and Advanced Super Dimension Switch (ADS) [2,3]. The ADS display mode is widely used in large-scale, high-definition displays and LCD TVs due to its advantages of hard screen, high transmittance, large view angle (both horizontal and vertical can reach 178°) and high color expression [4,5].…”

24.4L: Late‐News Paper: High Performance Advanced Super Dimension Switch (ADS) Mode LCD with Negative Dielectric Anisotropy LC Optimization

“…The LCD image quality has been greatly improved owing to extensive research on many new modes, such as in-plane switching (IPS) mode [1], multi-domain vertical alignment (MVA) mode [1], fringe field switching (FFS) mode [2], and ADvanced Super Dimension Switch (ADS) mode. ADS mode LCD is the proprietary LCD technology of BOE, which was known to exhibit wide-viewing angle, high contrast ratio, high transmittance.…”
