Title
(EN) A TOUCHSCREEN
(FR) ÉCRAN TACTILE
Abstract
(EN) A touch screen (TS) is provided that comprises a display; a frame with edges positioned opposite each other around the display; at least a first sensor array and at least a second sensor array, wherein each of the sensor arrays has a plurality of light transmitters and a plurality of light sensors, and wherein the at least first sensor array and the at least second sensor array are disposed on the first edge and the second edge of the frame, respectively, wherein the transmitters of the first sensor array are facing the light sensors on the second sensor array positioned on two opposing edges of the frame; and at least one physical obstacle located on the third edge or the fourth edge, for reducing stray light scattered or reflected by third edge or the fourth edge and arriving to the light sensors.
(FR) L'invention concerne un écran tactile (TS) qui comprend un dispositif d'affichage ; un cadre possédant des bords positionnés à l'opposé l'un de l'autre autour du dispositif d'affichage ; au moins un premier ensemble de capteurs et au moins un second ensemble de capteurs, chacun des ensembles de capteurs ayant une pluralité d'émetteurs de lumière et une pluralité de capteurs de lumière, et ledit premier ensemble de capteurs et ledit second ensemble de capteurs étant disposés sur le premier bord et le deuxième bord du cadre, respectivement, les émetteurs du premier ensemble de capteurs faisant face aux capteurs de lumière sur le second ensemble de capteurs positionnés sur deux bords opposés du cadre ; au moins un obstacle physique situé sur le troisième bord ou le quatrième bord, afin de réduire la lumière parasite diffusée ou réfléchie par le troisième bord ou le quatrième bord et atteignant les capteurs de lumière.
