The aim of this project is to make a study on the reduction of the aging time of aSony LCD television to increase its production at the company. The aging timeis a period of time when the turned on LCD television is working with a whitepattern, with the maximum luminance and the maximum backlight to adjust itscolorimetry and luminance levels.Due to the structure and design of production lines and the capacity needs ofthe company, the ageing time information specified by Design Departmentrepresents a bottleneck at the assembly process of the television. In fact, thereare two possibilities to get to the desired result with the necessary time. Thefirst one is to invest in structure and space to lengthen the production lines, andthe second and chosen one is to reduce the ageing time to increase theproduction.To reduce the ageing time we should find how to model the television behaviorout from a mathematical equation. Also, with the help of 6s parameter wewould estimate the behavior and the characteristics of the television with twovariables: the television operation time and the television exterior surfacetemperature, both of them correlated.With this information we will be able to determine which the minimum agingtime is in order to increase the production of televisions.
