Un dispositif d'éclairage électroluminescent organique ayant une fonction de dessin possède un panneau d'éclairage à DEL organique (111) qui éclaire un objet à éclairer, et une unité de dessin par laser (120) qui dessine des informations sur l'objet éclairé. L'objet éclairé est un bureau (40) sur lequel le dispositif d'éclairage ayant le panneau d'éclairage à DEL organiques (111) et l'unité de dessin par laser (120) a été placé, ou est un document (80) placé sur le bureau (40). L'unité de dessin par laser (120) dessine sur la surface du bureau (40) ou du document (80) un cadre en forme de boîte (50), des marqueurs (60) indiquant les quatre coins, et analogue, tel que des informations de référence de position indiquant des références de position lorsque le document (80) est placé sur le bureau (40).
