Patent ID: 8227983

Claim:
An OLED display device comprising: a sub-pixel driving array disposed on a first substrate; an OLED array disposed on a second substrate; a sealant to bond the first and second substrates to each other; a plurality of lower pads disposed on the first substrate; a plurality of upper pads disposed on the second substrate; and a plurality of conductive balls included in the sealant, wherein the upper pads are respectively connected with the lower pads through the conductive balls, wherein the OLED array includes a plurality of organic light-emitting diodes respectively disposed in sub-pixels, wherein each of the plurality of organic light-emitting diodes comprise: a transparent electrode on the second substrate; an organic light-emitting layer on the transparent; and a first electrode on the organic light-emitting layer connected with the sub-pixel driving array, wherein the upper pad is formed of the same transparent conductive layer and in the same layer as the transparent electrode at the same mask process, wherein the upper pads are extended from an inner area of the sealant of the second substrate to an outer area of the sealant of the second substrate which is outside the sealant, a circuit film is connected with the upper pads in the outer area of the sealant of the second substrate so that the circuit film does not overlap the sealant, and a driving chip is disposed on the circuit film; and wherein each of the lower pads include a first pad and a second pad, which is connected with the first pad through a contact hole, and is connected with each of the upper pads through the conductive balls.
