Reflectance-enhanced liquid crystal displays and thermochromic multi-color patterning

87‐2: Study on Optical Performances of New Structure Reflective Liquid Crystal Display with Advanced Polarizer Film†

“…Healthy eye-care display is becoming more and more important as individuals strive to live healthier lifestyles. More and more research is being done on RLCDs that eliminate backlight and use ambient light as the source of light because the blue band in LCD backlights is bad for human eyes [1][2][3][4][5][6][7][8][9] . The reflective metal in conventional RLCD cell serves as the reflective surface for RLCD, which typically modulates the light using 1/2λ and 1/4λ plate [1, 2 and 11] .…”

“…The chromaticity must be adjustable since varied application scenarios or consumers call for various bright state Chroma. In this work, we investigated the polarizer angle and the dichroic dye-doped liquid crystal [6,15] to adjust the Chroma of normal white mode display, making the selection of product design more flexible.…”

Unique Polymer-Stabilized Liquid Crystal Structure Prepared by Addition of a Reversible Addition–Fragmentation Chain Transfer Agent

“…Polymer-stabilized liquid crystals (PSLCs) are widely employed as functional composite materials in applications such as liquid crystal displays, spatial light modulators, smart windows, and microlenses. − In a typical PSLC, a small fraction of polymers (usually less than 10 wt %) are dispersed in a continuous liquid crystal (LC) phase, and the polymer network forms a template of the LCs . Without electrical fields, the LC molecules are aligned homogeneously due to the anchoring force provided by the alignment layer and polymer network.…”

ZnFe2O4/Graphitic Carbon Nitride Nano/Microcomposites for the Enhanced Electrochemical Sensing of H2O2

“…Hydrogen peroxide (H 2 O 2 ), as a vital reactive oxygen species, creates a wide demand for effective concentration monitoring in pharmaceutical, environmental, and food manufacturing areas, which is generated from certain classic biochemical reactions catalyzed by enzymes. − Therefore, it is urgent to develop a stable and precise detector to characterize the amount of H 2 O 2 , ranging from disease prevention to improvement in the quality of daily life. − Recently, some conventional techniques for H 2 O 2 determination have been reported, including fluorescence, spectrophotometry, and electrochemistry. − Among these traditional ways, the electrochemical method attracts great attention due to its rapid response, high sensitivity, and simple instruments . Under the potential scan conditions, H 2 O 2 can be directly oxidized or reduced on the surface of electrochemically active solid electrodes, while these processes are often confined by slow electrode kinetics in multistep chemical reactions and high overpotential, which will influence the sensing performances and trigger interferences from other existing electroactive species at the same time. − Currently, some research studies on the electrochemical detection of H 2 O 2 are mainly focused on electrode modification to promote the electron transfer and simultaneously decrease the electrode polarization . Up to date, various nanostructured materials have been introduced into electrode modification for acquiring the desirable chemical, physical, and electronic properties, including exfoliated graphitic carbon nitride/ZnO nanosheets, nanostructured ZnO thin films, Pt-SWCNT network films, etc. − As a novel two-dimensional (2D) semiconductor material, graphitic carbon nitride (g-C 3 N 4 ) has attracted abundant interest in the electrocatalysis field .…”
