Abstract
Since drop-impact is the most frequent cause of failure of mobile devices and the display is the major channel for users to interact with mobile devices, the reliability of the display module by drop-impact is one of the most important concerns for both manufacturers and customers. In this paper, we propose- a drop-impact reliability assessment method for the mobile display module using a statistical modeling approach. First, the general likelihood functions that consider various censored data are proposed to obtain accurate estimates. Second, under the constraints of the test budget and the sample size, the optimization problem for minimizing the mean squared error of the target of interest with the decision variables was proposed. The proposed method was applied to the real application example to determine the most reliable mobile display module design.
