Display device

1. A display device, comprising:

a rollable display panel comprising a first portion and a second portion the rollable display panel having a displaying side and a non-displaying side opposite to the displaying side, the rollable display panel comprising:

a substrate;

a plurality of light emitting units disposed on the substrate; and

a cover layer disposed on the substrate; and

a discharger disposed on one of the displaying side and the non-displaying side of the rollable display panel and outside the rollable display panel,

wherein in a rolled mode, the discharger is positioned between the first portion and the second portion of the rollable display panel.

2. The display device of claim 1 , wherein the discharger is a conductive layer having a conductivity ranged from 1*10 4 to 1*10 8 m −1 ohm −1 .

3. The display device of claim 2 , wherein the conductive layer is additionally connected to a conductor via a conductive glue.

4. The display device of claim 2 , wherein the conductive layer is grounded by being electrically connected to a common voltage node.

5. The display device of claim 4 , wherein the common voltage node is disposed on a circuit board.

6. The display device of claim 1 , wherein the discharger is disposed on the non-displaying side.

7. The display device of claim 1 , wherein the discharger is disposed on the displaying side.

8. The display device of claim 1 , wherein the discharger comprises a first via.

9. The display device of claim 8 , wherein the substrate comprises a second via, and the first via of the discharger is disposed corresponding to the second via of the substrate.

10. The display device of claim 8 , wherein in the rolled mode, the display device comprises a rolled structure and a non-rolled structure, and the rolled structure comprises the first via of the discharger.
