The invention relates to a display surface and a control device combined therewith for a data processing system, wherein the position of a light beam hitting the display surface is measured and the measured result is used by the data processing system as a basis for determining a cursor position on the display surface. Several strip-shaped optical position detectors (2) are arranged along the edge of the display surface (1), the measured signals of which are fed into the data processing system. The cross-sectional shape of the indicator beam (3) is formed by several lines which protrude both the display surface (1) and the position detectors (2) arranged thereon. The optical position detectors (2) are formed by a layered structure made of organic material.

L'invention concerne une surface d'affichage et un dispositif de commande combiné avec celle-ci pour une installation de traitement de données, la position d'un rayon lumineux incident sur la surface d'affichage étant mesuré et le résultat de la mesure étant utilisé par l'installation de traitement de données comme base pour fixer une position de curseur sur la surface d'affichage. Le long du bord de la surface d'affichage (1) sont disposés plusieurs détecteurs de position (2) optiques en forme de bande dont les signaux mesurés sont introduits dans l'installation de traitement de données. La forme de section transversale du rayon lancé (3) est formée par plusieurs lignes qui s'avancent tant au-delà de la surface d'affichage (1) que des détecteurs de position (2) disposés sur celle-ci. Les détecteurs de position (2) optiques sont formés par une structure en couches en matière organique.
