Embodiment Construction
[0027] As mentioned in the background art, the existing foam layer has poor heat dissipation capability, which will affect the performance and lifespan of the organic light emitting display device. The inventor found that the existing foam layer is formed by directly spraying the foaming agent on the base material. Different foaming agents have different formulas from different manufacturers, and the impact resistance of the foam produced is different, but the same thing is that the foam produced The heat dissipation capacity of the foam is relatively poor.
[0028] Based on this, the present invention provides a kind of protection structure, to overcome the above-mentioned problem that prior art exists, comprise:
[0029] The base material and the first foam layer located on the surface of the base material; the first foam layer includes a heat conduction layer, and the heat conduction layer is a grid structure.
[0030] The present invention also provides a method for makin...

Abstract
The invention provides a protective structure, a manufacturing method thereof, and an organic light-emitting display device. The protective structure includes a base material and a first foam layer located on the surface of the base material. The heat dissipation ability of the layer avoids the problems of poor performance and short life of the organic light-emitting display device due to the poor heat dissipation ability of the foam layer; and, since the heat conduction layer is a grid structure, therefore, spraying on the grid structure After the foaming agent forms the first foam layer, it can effectively reduce the generation of air bubbles attached between the first foam layer and the display panel, so that the bonding between the protective structure and the display panel is tighter and more stable.
Description
technical field [0001] The present invention relates to the technical field of organic light-emitting display, and more specifically, to a protective structure, a manufacturing method thereof, and an organic light-emitting display device. Background technique [0002] With the vigorous development of flat panel display technology, organic light emitting display devices (Organic Light Emitting Display, OLED for short) are more and more widely used due to their excellent characteristics such as self-illumination, high brightness, wide viewing angle, and fast response. However, compared with the liquid crystal display device, the organic light emitting display device has no backlight module protection, so the mechanical strength of the organic light emitting display device is relatively weak. Although in the prior art, the impact resistance of the organic light-emitting display device is improved by pasting a foam layer on the non-display surface of the organic light-emitting d...
