RT Journal Article T1 Louvers design for LED displays for sunny days A1 Vázquez Moliní, Daniel A1 Álvarez Fernández-Balbuena, Antonio A1 Alda Serrano, Javier A1 Bernabeu Martínez, Eusebio AB The use of louvers attached to variable information display needs to be optimized taking into account different intrinsic and extrinsic parameters. The analysis of the performance of the display–louvers system takes into account the location, orientation, and daily and seasonal variations. The observation of the system is divided depending on the distance of observation. The far distance vision performance use the background luminance. The medium distance performance needs the use of the Contrast Sensitivity Function of the eye. PB Elsevier Science Ltd.
