APPARATUS FOR FORMING ORGANIC LIGHT EMITTING LAYER AND METHOD OF FORMING ORGANIC LIGHT EMITTING LAYER USING THE SAME

摘要

An organic light-emitting layer forming apparatus includes a stage supporting an intermediate product of an organic light emitting device, which includes a substrate, and a pixel defining layer including first openings. The apparatus includes a first mask disposed over the stage and including second openings, and a second mask disposed over the first mask and including third openings. The second mask is movable relative to the first mask between first and second positions. The third openings do not overlap the second openings in the first position while overlapping the second openings in the second position. T he apparatus includes an inkjet head unit disposed over the second mask and supplying an organic material to the third openings of the second mask in the first position. The second mask moves to the second position to transfer the organic material through the second openings.

主权项

1. An apparatus for forming an organic light emitting layer, comprising:
a stage configured to support an intermediate product of an organic light emitting device, wherein the intermediate product comprises:
a substrate; anda pixel defining layer disposed over the substrate and including a plurality of first openings to define a plurality of pixel areas; a first mask disposed over the stage and comprising a plurality of second openings; a second mask disposed over the first mask and comprising a plurality of third openings, the second mask being movable relative to the first mask between a first position and a second position, wherein the third openings do not overlap the second openings when the second mask is in the first position and the third openings overlap the second openings when the second mask is in the second position; and an inkjet head unit disposed over the second mask and configured to substantially simultaneously supply an organic material to the third openings when the second mask is in the first position, wherein the second mask is configured to move to the second position to transfer the organic material through the second openings.
