Mask plate for vapor deposition of organic light-emitting diode (OLED) devices and OLED device thereof
View Patent ↗A mask plate for vapor deposition of an organ light-emitting diode (OLED) device and an OLED device manufactured thereby are provided. The mask plate has first slot-type mask portions disposed at intervals along a predetermined direction; second slot-type mask portions disposed at intervals along a direction perpendicular to the first slot-type mask portion and pixel regions into at least two displaying regions with the first slot-type mask portion. An intersection portion formed by the first slot-type mask portion and the second slot-type mask portion covers a connection hole connected to an auxiliary cathode.
1. A mask plate for vapor deposition of an organic light-emitting diode (OLED) device, comprising:
multiple first slot-type mask portions disposed at intervals along a predetermined direction;
multiple second slot-type mask portions disposed at intervals along a direction perpendicular to the predetermined direction of the first slot-type mask portions;
the first slot-type mask portions and the second slot-type mask portions dividing pixel regions corresponding to a substrate into at least two displaying regions, wherein the displaying regions are coating regions of an organic film of the OLED device on the substrate; and
the first slot-type mask portions and the second slot-type mask portions configured to cover non-coating regions of the substrate;
wherein two of the first slot-type mask portions and two of the second slot-type mask portions form an outer edge frame of the mask plate, intersection portions are formed by the first slot-type mask portions and the second slot-type mask portions, except for intersection portions corresponding to the outer edge frame, and wherein remaining intersection portions respectively cover connection holes connected to auxiliary cathodes, and
wherein each of the width of the first slot-type mask portion and the width of the second slot-type mask portion is greater than a diameter of each of the connection holes.
2. The mask plate as claimed in claim 1 , wherein, covering regions of the first slot-type mask portions and the second slot-type mask portions are located outside an extent of the displaying regions.
3. The mask plate as claimed in claim 2 , wherein the first slot-type mask portions and the second slot-type mask portions are located in positions corresponding to pixel partitioning posts, and the covering regions are located in an extent of a region of the pixel partitioning posts.
4. A mask plate for vapor deposition of an organic light-emitting diode (OLED) device, comprising:
multiple first slot-type mask portions at intervals along a predetermined direction;
multiple second slot-type mask portions disposed at intervals along a direction perpendicular to the predetermined direction of the first slot-type mask portions;
the first slot-type mask portions and the second slot-type mask portions dividing pixel regions corresponding to a substrate into at least two displaying regions, wherein the displaying regions are coating regions of an organic film of the OLED device on the substrate; and
the first slot-type mask portions and the second slot-type mask portions configured to cover non-coating regions of the substrate;
wherein each of intersection portions of the first slot-type mask portions and the second slot-type mask portions covers a connection hole connected to an auxiliary cathode,
wherein each of the width of the first slot-type mask portion and the width of the second slot-type mask portion is greater than a diameter of each of the connection holes.
5. The mask plate as claimed in claim 4 , wherein covering regions of the first slot-type mask portions and the second slot-type mask portions are located outside an extent of the displaying regions.
6. The mask plate as claimed in claim 5 , wherein the first slot-type mask portions and the second slot-type mask portions are located in positions corresponding to pixel partitioning posts, and the covering regions are located in an extent of a region of the pixel partitioning posts.
