Flexible display and manufacturing method thereof

Abstract

The invention discloses a flexible display and a manufacturing method thereof. The manufacturing method comprises the steps of A, carrying out surface treatment on a middle area of a carrier substrate so as to enable the middle area of the carrier substrate to have a hydrophobic property; B, evenly coating a polymer solution at the surface of the carrier substrate, then heating to enable the polymer solution to be cured through cross-linking, and forming a polymer film; C, carrying out surface treatment on the periphery of the polymer film so as to enhance adhesion between the polymer film and the carrier substrate; D, forming a blocking layer, a TFT (thin film transistor) array layer, an OLED (organic light emitting diode) layer and a packaging layer on the polymer film in sequence, and then stripping the flexible display from the carrier substrate along a cutting line. The method disclosed by the invention not only ensures that the flexible display has good adhesion when being manufactured, but also ensures that a display device is stripped easily from the carrier substrate after the flexible display is manufactured. Meanwhile, an adhesive does not need to be used, the preparation process of the device is simplified, and the temperature resistant performance of the flexible substrate is improved, thereby being suitable for manufacturing high-resolution flexible displays.

Description

technical field [0001] The invention relates to the field of flexible display devices, in particular to a flexible display and a manufacturing method thereof. Background technique [0002] Flexible displays have become a research hotspot in universities and research institutions at home and abroad in recent years, and are also the focus of major manufacturers competing for layout. The continuous progress of various advanced manufacturing processes and technologies has not only increased the screen size of flexible displays, but also continuously improved the display quality. Major manufacturers such as Samsung and LG have launched flexible AMOLED (active matrix organic light-emitting diode panel) display prototypes. . Compared with ordinary displays, flexible displays have many advantages: light weight, small size, thinness, and easy to carry; high and low temperature resistance, impact resistance, and earthquake resistance are stronger, and they can adapt to a wider workin...
