[0049] Based on the flexible cover above, see Figure 5 , the present invention also provides a method for manufacturing a flexible cover, the first embodiment of the method for manufacturing a flexible cover of the present invention specifically includes the following steps:

[0050] Step S1 , making the first flexible substrate 11 .

[0051] Specifically, the thickness of the first flexible substrate 11 depends on requirements, and may be selected to be 20-50 μm.

[0052] Specifically, the material of the first flexible substrate 11 is a bending-resistant material, such as polyethylene terephthalate, polyimide and other materials. Further, the material of the first flexible substrate 11 Polyimide material is preferred.

[0053] Step S2, forming a second flexible substrate 12 and an ink layer 13 on one side of the first flexible substrate 11, and forming a hardened layer 14 on the other side of the first flexible substrate 11; wherein, the ink layer 13 includes The first i...

Abstract

The invention provides a flexible cover plate, a production method of the flexible cover plate and a flexible OLED display device. The flexible cover plate comprises a first flexible base film, a second flexible base film, an ink layer and a hard coating, wherein the ink layer includes a first ink area and a second ink area, the space between the first ink area and the second ink area is filled with the second flexible base film, so that the partition difference of the first flexible base film caused by the ink layer is eliminated, thus a good fitting effect can be achieved by means of a thinner optical adhesive layer in the using process, the thickness of the flexible OLED display device is further reduced, the bending resistance of the flexible OLED display device is improved, meanwhilethe fitting difficulty of the flexible cover plate is reduced, and improvement of the yield rate is promoted.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a flexible cover plate, a manufacturing method thereof, and a flexible OLED display device. Background technique [0002] Organic Light Emitting Diode (OLED) displays have self-illumination, low driving voltage, high luminous efficiency, short response time, high definition and contrast, nearly 180° viewing angle, wide operating temperature range, and can realize flexible display and large It is recognized by the industry as a display device with the most potential for development due to its many advantages such as full-color display. [0003] Compared with traditional liquid crystal displays (Liquid Crystal Display, LCD), OLED displays do not require backlights, and use very thin organic material coatings and glass substrates. When current passes through, these organic materials will emit light. In addition , its biggest advantage is that it can be made into flexible products....
