The aim of this study is to increase the luminance performance of direct light emitting diodes (DLED) televisions through case design improvement. We first gather luminance measurements of several regions of active area displays for different DLED models, along with mechanical parameters such as distance to the active area from a point of cross-section view, lens orientation and a specifically calculated ratio parameter related to the layout. For each area, feature selection and multiple linear regression model selection steps are executed to decide on the most suitable model describing the relationship between parameters and the quantity of interest, luminance of the area under investigation. We then embed the regression equations into optimization models, that aim to find the design maximizing the attained luminance level subject to several design specific constraints. Finally, the luminance performance of the design found by the optimization model is compared to that of the previous designs used by the company. The results indicate that design found using the methodology described in this paper is superior to previously used designs, in terms of luminance performance
