This paper provides general guidelines and watch outs while conducting strength testing on LCD glass. Importance of failure modes, large deflections, membrane stresses, failure locations, device design, fatigue, fractography and strain gauging are di

Implications of cell gap variations on LCD performance, particularly Mura, are discussed. A model combining light transmission through LCD and its perception is presented, including an application. Such a model can be used as a guide to define glass

The four-point bend test is one of the most popular strength testing methods used to test LCD panels. Traditionally, a panel is assumed to be either a monolithic piece of glass or two independent pieces of glass sliding against each other. This paper

A ball drop test is amongst the tests used to assess the response of an LCD device under impact conditions. Two different glass thicknesses − 0.5 mm and 0.7 mm - were submitted to this test in consideration for this paper. The result of the testing

A novel graft copolymer consisting of commercial chlorosulfonated polyethylene and γ-benzyl-L-glutamate was synthesized. The graft yield was over 70% at a mild reaction condition while we did not observe any crosslinking reaction. Polypeptide units

The four-point bend test is used extensively to measure the edge (and surface) strength of AMLCD displays both in panel form and single substrate. The subtleties of four-point bend test for AMLCD panel applications and how one might use additional te

The biaxial strength using ring-on-ring (ROR) test and uniaxial strength using 4-point bend test (4PB) were measured for 13.3″ panels with substrate thicknesses ranging from 0.25 mm to 0.5 mm. The effect of thinning process was quantified by these
