Organic light-emitting diode module equipped with vertical electric connection structure

An organic light-emitting diode module equipped with vertical electric connection structure, comprising:

• a substrate which is extended toward a first direction and includes a first side and a second side separated in the first direction;
• a plurality of organic light-emitting diode (OLED) clusters located on the substrate in the first direction that include a first OLED and a second OLED opposing each other, and a third OLED and a fourth OLED that are located between the first OLED and the second OLED;
• an anode wire structure including:
• a bottom layer wire set which is located on the substrate and includes a first bottom layer wire extended toward the first side, a second bottom layer wire, a third bottom layer wire, a fourth bottom layer wire and a bottom layer external connection wire extended in the first direction, the first bottom layer wire, the second bottom layer wire, the third bottom layer wire and the fourth bottom layer wire including respectively one end formed electric connection with the first OLED, the second OLED, the third OLED and the fourth OLED, the bottom layer external connection wire forming electric connection between another end of the third bottom layer wire and the fourth bottom layer wire, wherein the third bottom layer wire and the fourth bottom layer wire include respectively an extended length smaller than or equal to the first bottom layer wire and the second bottom layer wire;
• an insulation layer which is located on the bottom layer wire set and includes a first through hole and a second through hole that correspond to another end of the first bottom layer wire and another end of the second bottom layer wire;
• a middle layer wire set including a first middle layer wire located in the first through hole to form electric connection with the another end of the first bottom layer wire and a second middle layer wire located in the second through hole to form electric connection with the another end of the second bottom layer wire;
• and
• a top layer wire set which is located on the insulation layer and includes a top layer internal connection wire to connect between the first middle layer wire and the second middle layer wire;
• and
• a cathode wire structure which is located on the substrate and extended in the first direction to form electric connection with the first OLED, the second OLED, the third OLED and the fourth OLED.
