Display device having a desiccant member contacting a common electrode
View Patent ↗A display device includes a display panel divided into a display area and a non-display area. An encapsulation member covers the display panel, and a sealant is positioned between the display panel and the encapsulation member. A desiccant member is disposed between the display panel and the encapsulation member. The display panel includes an organic layer formed in the display area and a common electrode covering the organic layer, the common electrode extending in the non-display area. The desiccant member is disposed along a periphery of the common electrode in the non-display area.
1. A display device comprising:
a display panel divided into a display area and a non-display area;
an encapsulation member covering the display panel;
a sealant positioned between the display panel and the encapsulation member; and
a desiccant member disposed between the display panel and the encapsulation member,
the display panel comprising an organic layer formed in the display area and a common electrode covering the organic layer, a portion of the common electrode extending in the non-display area, and
wherein the desiccant member contacts an upper surface and a side surface of an edge of the common electrode in the non-display area without covering the display area.
2. The display device of claim 1 , wherein the desiccant member has a width in the range of from about 0.5 mm to about 10 mm.
3. The display device of claim 1 , wherein the desiccant member has a thickness in the range of from about 0.1 mm to about 1 mm.
4. The display device of claim 1 , wherein the desiccant member is made by drying a liquid desiccant coated along the periphery of the common electrode and activating the dried desiccant.
5. The display device of claim 4 , wherein the liquid desiccant is dried within a temperature range of from about 40 degrees Celsius to about 90 degrees Celsius.
6. The display device of claim 4 , wherein the activating of the dried desiccant comprises directing a laser beam on the dried desiccant.
7. The display device of claim 1 , wherein the display panel further comprising a substrate member, a plurality of thin film transistors disposed on the substrate member and a plurality of pixel electrodes connected to a portion of the plurality of thin film transistors, and further wherein the organic layer is disposed on the pixel electrodes.
8. The display device of claim 1 , further comprising at least one other desiccant member supported by the encapsulation member.
9. The display device of claim 8 , wherein the at least one other desiccant member is supported on at least one of the display area and the non-display area.
10. The display device of claim 1 , wherein the desiccant member is thicker than the common electrode.
