Investigation of PDA LCD Screen Failures Under Humidity Cycling and Bending Loads

Liquid crystal displays are commonly used in various applications and subjected to numerous environmental and handling conditions that can especially affect the performance and life of these devices. In addition to humidity and temperature exposure, cyclic loadings and handling conditions (bending, repetitive shock, and drop loading) have been shown to cause failures in LCDs. Due to the large number of variable failure modes and use conditions, the question arises: how long can a LCD survive before a failure occurs…
