Abstract
A display structure is provided. The display structure includes a substrate, a dam, a first film layer, a second film layer, and a third film layer. The third film layer has a first spread rate for the first film layer, the third film layer has a second spread rate for the second film layer, and the first spread rate is less than the second spread rate. The spread rates of the third film layer on the first and second film layers are different, so as to slow the spread rate of the third film layer near an area of the dam, thereby reducing the risk that the third film layer overflows the dam, so that the encapsulation reliability of the display structure can be improved.
Claims18
A display structure, comprising:
- a substrate;
- a dam disposed on the substrate;
- a first film layer disposed on the substrate and covering the dam;
- a second film layer disposed on the substrate, a first gap located between the second film layer and the dam;
- and
- a third film layer disposed on the substrate, the first film layer, and the second film layer,
- wherein when the third film layer is disposed on the first film layer and the second film layer, the third film layer is in contact with the first film layer at the first gap, and a material of the first film layer is different from a material of the second film layer,
- wherein the third film layer has a first spread rate for the first film layer, the third film layer has a second spread rate for second film layer, and the first spread rate is less than the second spread rate.
A display structure, comprising:
- a substrate;
- a dam disposed on the substrate;
- a first film layer disposed on the substrate;
- and
- a second film layer disposed on the substrate, a first gap located between the second film layer and the dam,
- wherein the first film layer has a first oxygen content, the second film layer has a second oxygen content, and the second oxygen content is greater than the first oxygen content.
A display structure, comprising:
- a substrate;
- a dam disposed on the substrate;
- a first film layer disposed on the substrate and covering the dam;
- a second film layer disposed on the substrate, a first gap located between the second film layer and the dam;
- and
- a third film layer disposed on the substrate, the first film layer, and the second film layer,
- wherein when the third film layer is disposed on the first film layer and the second film layer, the third film layer has a first spread rate for the first film layer, the third film layer has a second spread rate for the second film layer, and the first spread rate is less than the second spread rate.
