Embodiment 1

[0047] Such as figure 1 As shown, the flexible display device of this embodiment includes: a plastic substrate 1 , a flexible display device 2 formed on the surface of the plastic substrate 1 , and a glass substrate 3 located on the side of the plastic substrate 1 away from the flexible display device 2 . Wherein, the glass substrate 3 in the present invention is an ultra-thin glass substrate, specifically refers to a glass substrate with a thickness less than or equal to 0.1 mm. Laser cutting is used to obtain smooth edges, so that the glass substrate 3 has the performance of not being damaged after conventional bending.

[0048]Further, the flexible display device of this embodiment further includes a driving circuit (not shown in the figure) for driving the flexible display device. The driving circuit may be a driving circuit directly formed around the display area of ​​the flexible display device on the first flexible substrate to drive the flexible display device, simila...

Embodiment 2

[0061] In order to achieve better encapsulation and better water and oxygen barrier, on the basis of Embodiment 1, a glass substrate is attached to the other side of the plastic substrate 1 , that is, the surface of the flexible display device 2 . Such as image 3 As shown, the surface of the plastic substrate 1 away from the flexible display device 2 is attached to the glass substrate 3a, and the surface of the flexible display device 2 is attached to the glass substrate 1a.

[0062] During production, the plastic substrate 1 and the glass substrate 3b are attached after step S3, or the surface of the flexible display device 2 is attached to the glass substrate 3b after step S2, and then step S3 is performed, that is, the plastic substrate 1 is separated from the flexible display device 3b. One side of the display device 2 is attached to the glass substrate 3a. The attachment of the plastic substrate 1 and the glass substrate 3b can be realized by means of adhesive or atmosp...

Embodiment 3

[0065] The flexible display device in this embodiment is a flexible display device obtained by replacing the glass substrate 3 in the flexible display device in Embodiment 1 or Embodiment 2 with a metal foil 5, which also achieves better water and oxygen barrier properties. Its preparation process is similar to that of Example 1 or Example 2, and will not be repeated here. Such as Figure 4 shows a flexible display device in which the glass substrate 1 in the flexible display device in Example 1 is replaced with a metal foil 5 .

Abstract

The invention discloses a flexible display device and relates to the technical field of display. The device comprises a first flexible substrate, a flexible display part and a second flexible substrate, wherein the flexible display part is formed on the surface of the first flexible substrate; the second flexible substrate is positioned at one side of the first flexible substrate, which is deviated from the flexible display part. The invention also provides a manufacturing method of the flexible display device, which comprises the following steps of: manufacturing the flexible display part on the first flexible substrate; and adhering the surface of the first flexible substrate with the flexible display part, which is deviated from the flexible display part, onto the second flexible substrate. According to the flexible display device disclosed by the invention, the flexible display part is packaged by the additional flexible substrate (the second flexible substrate) and particularly the flexible display part formed on a plastic substrate is packaged by adopting an ultrathin glass substrate, so that the flexible display device has better waterproof oxygen-proof property on the basis of keeping the flexibility and the bendable property and is difficult to damage.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a flexible display device and a manufacturing method thereof. Background technique [0002] With the development of flexible display technology, flexible display products that are closer to the traditional display mode will soon enter the homes of ordinary people. Due to the unique bendable characteristics of the flexible display itself, it is determined that it will have many special user experiences. [0003] The display modes and related devices that can realize flexible display mainly include liquid crystal display, organic electroluminescence display, electronic paper, electrophoretic display, touch screen, micro-electro-mechanical systems (Micro-Electro-Mechanical Systems, MEMS), thin-film photovoltaic cells. Among them, organic electroluminescent displays, electronic paper, electrophoretic displays, and thin-film photovoltaic cells are particularly sensitive to water and...
