Problems solved by technology

[0003] The invention provides a flexible display panel and its preparation method and display device. The flexible display panel can adjust the position of the neutral layer in the bending area through the neutral layer adjustment layer, so that the thin film transistor layer and the encapsulation layer are in the neutral position when bending. Layer position, to solve the problem that the thin film transistor layer and packaging layer of the existing flexible display panel cannot meet the requirements of tensile and compressive stress at the same time

Embodiment approach

[0044] Method 1, such as Figure 5 As shown in the structure, the first Young's modulus of the first neutral layer regulating layer 151 is smaller than the second Young's modulus of the second neutral layer regulating layer 152 .

[0045] Since the first Young's modulus of the first neutral layer regulating layer 151 is smaller than the second Young's modulus of the second neutral layer regulating layer 152, the first Young's modulus of the first neutral layer regulating layer 151 Smaller, the position of the neutral layer 18 in the first bending region A is moved up, and the position of the neutral layer 18 is adjusted to the encapsulation layer 14 by adjusting the first Young's modulus; while the second neutral layer adjusts the second position of the layer 152 The Young's modulus is relatively large, so that the position of the neutral layer in the second bending region B is moved down, and the position of the neutral layer 18 is adjusted to the thin film transistor layer 1...

Abstract

The invention relates to the technical field of display, in particular to a flexible display panel, a preparation method of the flexible display panel and a display device. The flexible display panelis provided with a first bending area and / or a second bending area; neutral layer adjusting layers are arranged at the positions, corresponding to the first bending area and the second bending area, on the flexible display panel, and the neutral layer adjusting layers are used for adjusting the position of a neutral layer in the first bending area to a thin film transistor layer and adjusting theposition of a neutral layer in the second bending area to a packaging layer. According to the flexible display panel, the problem that the thin film transistor layer and the packaging layer of an existing flexible display panel cannot meet the requirements of pulling and pressure stress simultaneously can be solved through the neutral layer adjusting layers.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a flexible display panel, a preparation method thereof, and a display device. Background technique [0002] With the rapid development of display technology, flexible display panels that can be folded have become a research and development hotspot in the display field. When the flexible display panel is a multi-fold product, the thin film transistor (Thin Film Transistor, TFT) layer and the encapsulation layer of the flexible display panel need to face relatively harsh bending conditions at the same time, so that the thin film transistor layer and the encapsulation layer of the flexible display panel cannot meet the requirements at the same time. Tensile and compressive stress requirements. Contents of the invention [0003] The invention provides a flexible display panel and its preparation method and display device. The flexible display panel can adjust the position of the ...
