Embodiment 1

[0047] An embodiment of the present invention provides a display device, such as figure 2 shown. Among them, the display module is described by taking a cube structure and a film barrier layer covering the four sides of the display module as an example, and the four sides of the cube display module are defined as the top surface a, the bottom surface b, and the top surface The first direction side c and the second direction side d between a and the bottom surface b. The display device includes a display module 10, and a film barrier layer composed of several barrier films (such as a first barrier film 21 and a second barrier film 22). Wherein, each barrier film covers three consecutive adjacent surfaces of the display module 10; the film barrier layer composed of all barrier films covers the display module 10 to form a closed cavity, and the display module 10 is arranged in the cavity .

[0048] Among them, the material of the barrier film can be an inorganic dielectric ma...

Embodiment 2

[0071] An embodiment of the present invention provides a display device, such as Figure 4 As shown, the difference from Example 1 is that the first barrier film 21 and the second barrier film 22 are intersected, that is, the first barrier film 21 covers one surface of the second barrier film 22, and the second barrier film 22 covers the second barrier film 22. One side of a barrier film 21.

Embodiment 3

[0073] An embodiment of the present invention provides a method for manufacturing a display device, such as Figure 5 shown, including the following steps:

[0074] Step S11, forming a display module on the substrate.

[0075] Step S12, a layer of barrier film is adhered to at least one surface of the display module.

[0076] Wherein, a layer of barrier film can be attached to one surface of the display module 10 , or a layer of barrier film can be attached to multiple surfaces of the display module 10 at the same time. For example, a barrier film may be laminated on the top surface and the corresponding bottom surface of the display module 10 .

[0077] Step S13 , bending the barrier film along the edge of the surface of the display module to cover at least two consecutive adjacent surfaces of the display module, wherein the consecutive adjacent surfaces are not in the same plane.

[0078]After a layer of barrier film is attached to one surface of the display module 10, th...

Abstract

The invention belongs to the display technological field and provides a display device and a preparation method thereof. The display device comprises a display module set and a thin film barrier layer; the thin film barrier layer is composed of a plurality of barrier thin films; and the thin film barrier layer covers the continuous adjacent surfaces of the display module set, wherein the continuous adjacent surfaces comprise at least a top surface, a bottom surface, a first direction side surface and a second direction side surface which are oppositely arranged between the top surface and thebottom surface. According to the display device and the preparation method thereof of the invention, the thin film barrier layer is adopted to realize bilateral or multilateral wrapping for the display module set, so that the travel distance of water and oxygen entering the display module set is greatly increased, namely, the thin film barrier layer which wraps two sides or a plurality of sides ofthe display module set prolong a penetration path through which the external water and oxygen enter the display module set, and therefore, the water and oxygen blocking performance of the display device can be greatly improved, the display device can be protected, and the service life of the display device can be prolonged; and the mechanical strength of the screen body of the display device is increased.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display device and a preparation method thereof. Background technique [0002] At present, the successful mass production of organic electroluminescent devices not only greatly benefits the new generation of high-end smartphone industry, but also has a profound impact on the application of wearable devices due to their low power consumption and bendable characteristics. And in the future development, flexible screens will be widely used with the continuous penetration of personal smart terminals. [0003] The organic material of the organic electroluminescent device is very sensitive to water and oxygen. A small amount of water and oxygen will cause oxidation, crystallization or electrode deterioration of the organic material in the display screen, affecting the life of the display screen or directly causing damage to the display screen. Vitex Systems has developed a Barix pa...
