Abstract

A display module includes a display panel, an external frame, and a pad structure. The external frame is disposed at a side of the display panel. The pad structure is disposed between the display panel and the external frame. A panel-absorbing portion is formed on a surface of the pad structure facing the display panel. The panel-absorbing portion is used for absorbing the display panel so as to fix the pad structure on the display panel.

Claims

1. A display module comprising:

a display panel;

an external frame disposed at a side of the display panel; and

a pad structure disposed between the display panel and the external frame, a panel-absorbing portion being formed on a surface of the pad structure facing the display panel, a hollow space of the panel-absorbing portion being isolated from an ambient atmosphere outside the pad structure when the pad structure is sandwiched by the display panel and the external frame, so that the panel-absorbing portion is absorbed onto the display panel when air is extruded from the hollow space of the panel-absorbing portion to make the hollow space of the panel-absorbing portion be in a nearly-vacuum state, for fixing the pad structure on the display panel.

2. The display module of claim 1, wherein an extended part is formed at a side of the pad structure, a slot structure is formed on the external frame corresponding to the extended part, and the extended part is used for engaging with the slot structure so as to fix the pad structure on the external frame.

3. The display module of claim 1, wherein the pad structure is a ring-shaped pad disposed around the external frame.

4. The display module of claim 1, wherein the pad structure comprises a plurality of pads, and the plurality of pads is discontinuously disposed around the external frame.

5. The display module of claim 4, wherein an extended part is formed at a side of each pad respectively, a slot structure is formed on the external frame corresponding to the extended part, and each extended part is used for engaging with the corresponding slot structure so as to fix the corresponding pad on the external frame.

6. The display module of claim 1, wherein the panel-absorbing portion is a circular recessed structure.

7. The display module of claim 1, wherein a frame-absorbing portion is formed on a surface of the pad structure facing the external frame, and a hollow space of the frame-absorbing portion is isolated from the ambient atmosphere outside the pad structure when the pad structure is sandwiched by the display panel and the external frame so that the frame-absorbing portion is absorbed onto the external frame when air is extruded from the hollow space of the frame-absorbing portion to make the hollow space of the frame-absorbing portion be in a nearly-vacuum state, for fixing the pad structure on the external frame.

8. The display module of claim 7, wherein the frame-absorbing portion is a circular recessed structure.

9. The display module of claim 1, wherein the pad structure is made of flexible material.

10. The display module of claim 9, wherein the pad structure is made of silicone rubber material.
