An important aspect of mechanical reliability of LCD panels is to understand and quantify their response to impact loading. This paper studies the behavior of 17″ modules impacted by a spherical ball traveling at a speed of up to ∼1 m/sec. At this velocity, the deformation response of the module system is significantly different from that during quasi-static loading. In view of much shorter duration of impact test, the LCD panels can sustain relatively large loads without any measurable slow crack growth. The test data show that the dynamic strength of these panels, estimated from fracture mirror, is significantly higher than their quasi-static strength. With higher strength and immeasurable slow crack growth the LCD panels should not experience cumulative damage during multiple impact loading implying that their mechanical reliability under such loading is excellent. |
