Embodiment 1

[0040] Such as Figure 1 to Figure 6 As shown, the present embodiment provides a flexible substrate.

[0041] The flexible substrate of this embodiment can be used as a substrate for a flexible organic light emitting diode (OLED) display substrate, that is, display structures such as organic light emitting diode (OLED) devices 9 , pixel circuits, and leads are formed thereon.

[0042] Wherein, the flexible substrate includes at least two stacked flexible layers, the flexible layers include inorganic layers and organic layers, and at least one side of at least one flexible layer is formed with a hydrophobic layer 4 .

[0043] Because it is flexible, a flexible layer must be included in the flexible substrate, and usually the flexible layer will include at least one organic layer made of organic materials, and an inorganic layer made of inorganic materials; wherein at least one flexible layer (which can be An organic layer, or an inorganic layer) is formed with a hydrophobic la...

Embodiment 2

[0078] Such as Figure 1 to Figure 6 As shown, the present embodiment provides a flexible organic light emitting diode (FOLED) display substrate, which includes:

[0079] the aforementioned flexible substrate;

[0080] A plurality of organic light emitting diode devices 9 are formed on one side of the flexible substrate.

[0081] That is to say, the above flexible substrate can be used as a substrate, on which a plurality of organic light emitting diode (OLED) devices 9 serving as sub-pixels are formed, thereby obtaining a flexible organic light emitting diode display substrate.

[0082] Of course, in the flexible OLED display substrate, in addition to the OLED device 9 , other known structures such as pixel circuits, gate lines, data lines, and packaging structures 8 may also be formed, which will not be described in detail here.

[0083] Preferably, for the above-mentioned flexible substrate with five flexible layers; a plurality of organic light emitting diode devices 9 a...

Abstract

The invention provides a flexible substrate and a preparation method thereof and a flexible organic light emitting diode display substrate belonging to the technical field of the flexible organic light emitting diode display, and can at least partially solve the problems of short service life and low reliability of the existing flexible organic light emitting diode display substrates. The flexiblesubstrate of the present invention comprises at least two stacked flexible layers, the flexible layers comprising an inorganic layer and an organic layer, and at least one side of at least one flexible layer forms a hydrophobic layer.

Description

technical field [0001] The invention belongs to the technical field of flexible organic light emitting diode displays, and in particular relates to a flexible substrate, a preparation method thereof, and a flexible organic light emitting diode display substrate. Background technique [0002] Organic Light Emitting Diode (OLED) display technology has the advantages of fast response, active light emission, low power consumption, simple structure, etc., so it has been widely used. Wherein, since the organic light emitting diode device is easily corroded by water vapor (water vapor), in the organic light emitting diode display substrate, the organic light emitting diode needs to be packaged on the side away from the substrate to isolate the water vapor. [0003] With the development of technology, flexible organic light-emitting diode (FOLED) display substrates have also been used. The base of the flexible organic light-emitting diode display substrate is a flexible substrate ma...
