InactiveCN107293554ASimple structureSimple manufacturing processTransistorSolid-state devicesInsulation layerManufacturing technology
The present invention provides a top-emitting-type OLED panel manufacturing method and the structure thereof. In the top-emitting-type OLED panel manufacturing method, through the patterned treatment of a first metal layer, a light blocking layer and a light reflecting layer are fabricated, which simplifies the manufacturing technology for an anode and reduces the risk for bad problems. After a gate electrode and a gate electrode insulation layer are fabricated on an oxide semiconductor layer, plasma treatment is performed on the entire surface of the oxide semiconductor layer so that the part of the oxide semiconductor layer not covered by the gate electrode and the gate electrode insulation layer is reduced in resistance and forms a conductor layer, while the part blocked by the gate electrode and the gate electrode insulation layer is still a semiconductor and forms a semiconductor channel region. The conductor layer is used as the anode of a white light OLED, which can eliminate yellow light for fabricating the anode independently and an etching process. In addition, the fabrication of a traditional flattening layer and a pixel defining layer can both be eliminated, therefore, reducing the number of procedures for yellow light fabricating, reducing the number of light covers and cutting the fabricating cost. The use of an ink-jet printing OLED light-emitting layer further keeps the manufacturing cost down.
