Problems solved by technology

[0003] At present, the flexible AMOLED substrate under the PI substrate is usually a single foam, PMMA and other materials. Although they are polymers that can absorb external impact energy, there are certain differences in the amount of external impact energy absorbed. , but the deformation generated at the impact point is the largest at the impact point, so that even if the substrate material absorbs the energy from the impact point, the OLED pixel at the corresponding display position is prone to failure. This is the technology in the art what people don't expect to see

Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0017] Such as figure 1 As shown, this embodiment discloses a flexible AMOLED substrate, specifically, the flexible AMOLED substrate includes several double-layer structures 1 stacked in sequence (the figure only shows that the flexible AMOLED substrate includes two double-layer structures 1 Structure 1, in fact, the flexible AMOLED substrate may include 1, 3 or more double-layer structures 1): the double-layer structure 1 includes a first polymer material layer 11 and a The second polymer material layer 13 on the top, and the first polymer material layer 11 and the second polymer material layer 13 are bonded together by adhesive 12, wherein the material of the second polymer material layer 13 is amorphous Polymers, this is due to the characteristics of amorphous polymers that change from soft ...

Abstract

The invention relates to the technical field of displays, and particularly relates to a flexible AMOLED substrate and a preparation method thereof. Through preparing the substrate which at least comprises a bi-layer structure formed by bonding of a first polymer material layer and a second polymer material layer, the second polymer material layer is made of amorphous polymer, when the AMOLED substrate is subjected to external impact, point deformation at the impact point is converted to surface deformation, the deformation amount at the impact point is reduced, and failure of an OLED pixel point at a corresponding position is avoided.

Description

technical field [0001] The invention relates to the technical field of displays, in particular to a flexible AMOLED substrate and a preparation method thereof. Background technique [0002] OLED is an Organic Light-Emitting Diode (Organic Light-Emitting Diode), which has the characteristics of self-illumination, high brightness, wide viewing angle, high contrast, flexibility, and low energy consumption. It began to gradually replace traditional liquid crystal displays and was widely used in mobile phone screens, computer monitors, full-color TVs, etc. [0003] At present, the flexible AMOLED substrate under the PI substrate is usually a single foam, PMMA and other materials. Although they are polymers that can absorb external impact energy, there are certain differences in the amount of external impact energy absorbed. , but the deformation generated at the impact point is the largest at the impact point, so that even if the substrate material absorbs the energy from the im...
