BACKSIDE-EMITTING OLED DEVICE

An OLED device includes a transparent anode of given sheet resistance R1, a cathode of given sheet resistance R2, the ratio r=R2/R1 ranging from 0.1 to 5, a first anode electrical contact and a first cathode electrical contact which is offset from the anode electrical contact, for any point B1 of ea...

Summary:An OLED device includes a transparent anode of given sheet resistance R1, a cathode of given sheet resistance R2, the ratio r=R2/R1 ranging from 0.1 to 5, a first anode electrical contact and a first cathode electrical contact which is offset from the anode electrical contact, for any point B1 of each anode contact, on defining a distance D1 between the point B1 and a point C1 of the contact surface which is closest to the point B1, and on defining a distance L1 between the point B1 and a point X1 of a second edge of the active zone opposite from the first edge, passing through C1, then the following criteria are defined: if 0.1 r<1.75, then 20%<D1/L1, if 1.75 r<2.5, then 20%<D1/L1<90%, or if 2.5 r<3, then 20%<D1/L1<80%, or else if 3 r 5 then 20%<D1/L1<70%, and a reflector (6) covers the active zone (20).
