Apparatus for manufacturing display panel and method for manufacturing the same
View Patent ↗An apparatus for manufacturing a display panel includes an arriving part in which an unfinished display panel is disposed. The apparatus has at least one light transmitting part, a mold which is positioned on the arriving part and which includes at least one alignment key and a pattern forming part, a mold driver which drives the mold, and an alignment sensor which is positioned under the arriving part and which determines whether the display panel and the mold are erroneously aligned through the light transmitting part. Therefore, it is possible to efficiently and accurately pattern a specific material onto the display panel through an imprint lithography process using a pressing mold.
1. A method of manufacturing a display panel comprising:
providing a display panel comprising a display area and a non-display area which is formed around the display area and which includes at least one first alignment key formed in the non-display area;
disposing the display panel in an arriving part having a light transmitting part;
coating an organic film on the display panel;
pressurizing the organic film using a mold including at least one second alignment key and a pattern forming part, the at least one second alignment key being disposed outside of the pattern forming part;
determining whether the display panel and the mold are erroneously aligned by confirming an aligned state of the first alignment key and the second alignment key through the light transmitting part after pressurizing the organic film using the mold;
hardening the organic film; and
removing the mold from the hardened organic film.
2. The method of claim 1 , further comprising etching the organic film after the removing the mold.
3. The method of claim 1 , wherein the determining whether the display panel and the mold are erroneously aligned includes
irradiating an alignment sensing light through the light transmitting part; and
determining a positional relationship between the first alignment key and the second alignment key by sensing a reflection of the alignment sensing light from either of the first and second alignment sensing keys.
4. The method of claim 1 , further comprising a step between determining whether the display panel and the mold are erroneously aligned and hardening the organic film, the step comprising aligning the display panel and the mold by relatively moving at least one of the display panel and the mold.
5. The method of claim 1 , wherein the organic film is a resin film.
6. The method of claim 1 , wherein at least one of heat hardening and ultraviolet hardening is used in hardening the organic film.
7. The method of claim 6 , further comprising additionally hardening the organic film which is positioned in a part corresponding to the second alignment key when ultraviolet hardening is used in the hardening the organic film.
