Abstract
The impact behavior of TFT-LCD module is very complicated because the module is assisted with three parts such as back light unit, LCD Panel and top chassis. Especially, the back light unit is constructed with several small and thin parts made by plastics or steels. The design of the back light unit is very important because the recent demand is more lighter, thinner and narrower module. The aim of the present study is the investigation of mechanical characteristics during impact loading. The back light unit must assist TFT-LCD Panel made by glass and guide qualification of handling environment. This paper focus on the dynamic behavior of module and carries out a series of computer simulation using LS-DYNA program. Comparing with test results previously performed, dynamic characteristics of TFT-LCD module are estimated.
