Fabrication of poly(methyl methacrylate) microsphere added pressure-sensitive adhesives and their physical characteristics

Effects of thermomechanical properties of polarizer components on light leakage in thin-film transistor liquid-crystal displays

“…Recently, Nagamoto et al reported an LCD having a PSA with storage elastic modulus higher than 0.38 MPa to be practically usable with significantly reduced light leakage. 19) Numerous methods for enhancing the mechanical strength of PSA such as adding an oligomer crosslinker to PSA 20) and adding spherical poly(methyl methacrylate) microbeads to PSA 21) have also been proposed.…”

Stress and stress relaxation behaviors of multi-layered polarizer structures under a reliability test condition characterized by use of a bending beam technique

“…This stress may impose serious reliability issues and cause mechanical failure of films, such as warpage, 7) contact peel-off 13,16) and phase retardation or light-leakage phenomena. 18) To date, a vast amount of studies [13][14][15][16][17][19][20][21] have focused on the relationship between modified materials such as adhesive layers, and their optical characteristics, with the aim of reducing light-leakage. For example, the evolution and relaxation ability of key components such as PSA films have been studied 13,16,17,20) by exploring the dependence of their elastic (GA) or loss (GAA) moduli as a function of either frequency or temperature.…”
