Abstract

The invention provides a flexible display and a preparation method thereof. The flexible display comprises a channel layer, a gate insulating layer, a first electrode layer and a dielectric layer which are formed on a flexible substrate from bottom to top in sequence; the dielectric layer wraps the first electrode layer and is superposed with the gate insulating layer in an attaching manner; a first hole penetrating through the dielectric layer and the gate insulating layer is formed in the dielectric layer and the gate insulating layer and ends at the upper surface of the channel layer; an organic filler which at least can completely coat the surface of the first hole and absorb the stress is formed at the first hole; a second hole is formed by removing a part of organic filler; an organic matter layer capable of absorbing the stress is formed between the second hole and the first hole; a second electrode layer is deposited in the second hole. According to the flexible display and the preparation method thereof provided by the invention, stress energy generated by the electrode layers and the insulating layer in the bending process can be buffered, so that the display effect is improved.

Description

technical field [0001] The invention relates to the technical field of displays, in particular to a flexible display and a preparation method thereof. Background technique [0002] Flexible displays have many advantages, such as impact resistance, strong shock resistance, light weight, small size, and more convenient to carry. [0003] At present, the main flexible displays can be roughly divided into three types: electronic paper (or flexible electrophoretic display), flexible organic light emitting diode (Organic Light Emitting Diode, OLED) and flexible liquid crystal. [0004] The biggest feature of the flexible screen is that it can be bent and folded. During the bending process of the screen body, the most likely to cause failure damage is the contact interface between the metal and the inorganic film. Due to the large difference in fatigue characteristics, the inorganic film is prone to cracks during bending, and the metal layer is easily damaged by the stress of the...
