Shadow mask and method of fabricating organic light-emitting device using the same
View Patent ↗A shadow mask and a method of fabricating an OLED display using the same is disclosed, wherein the shadow mask is not sagging, and the shadow mask includes a plurality of columns, each column including a plurality of first or second cell-forming parts, wherein the first and second cell-forming parts are alternately arranged in the columns, and the first and second cell-forming parts provided in the adjacent columns include transmission parts having the different open directions.
1. A method of fabricating an OLED display comprising:
preparing a shadow mask including a plurality of odd and even-numbered columns divided by first shielding parts, each odd-numbered column including a plurality of first cell-forming parts divided by second shielding parts and each even-numbered column including a plurality of second cell-forming parts divided by third shielding parts, wherein the first and second cell-forming parts provided in the adjacent columns include a plurality of transmission parts formed as the open type having different open directions and a plurality of fourth shielding parts formed between the transmission parts;
positioning the shadow mask below a substrate; and
forming an organic light-emitting layer by supplying the organic light-emitting material layer from the organic light-emitting material supplier positioned below the shadow mask to the substrate through the transmission parts of the shadow mask while shielding the organic light-emitting material layer from an organic light-emitting material supplier through the first to fourth shielding parts of the shadow mask.
2. A method of fabricating an OLED display comprising:
preparing a shadow mask including a plurality of odd and even-numbered columns and rows, each odd-numbered column including a plurality of first cell-forming parts and each even-numbered column including a plurality of second cell-forming parts, each cell-forming part including a plurality of transmission parts formed as the open type, wherein the first cell-forming parts are positioned in the odd-numbered rows, and the second cell-forming parts are positioned in the even-numbered rows, and wherein the shadow mask has shielding parts between the first cell-forming parts in each odd-numbered column, between the second cell-forming parts in each even-numbered column and between the transmission parts of each cell-forming part;
positioning the shadow mask below a substrate; and
forming the organic light-emitting layer by supplying an organic light-emitting material layer from an organic light-emitting material supplier positioned below the shadow mask to the substrate through the transmission parts of the shadow mask while shielding the organic light-emitting material layer from the organic light-emitting material supplier through the shielding parts of the shadow mask,
wherein all of the transmission parts of the first and the second cell-forming parts are of identical width and length and are formed in the same direction at fixed intervals.
