Abstract

The invention discloses a flexible display panel and a preparation method thereof. The flexible display panel comprises a substrate, a circuit driving layer, a light emitting device layer, a packaginglayer and an organic filling layer, wherein the circuit driving layer is arranged on the substrate, the circuit driving layer comprises a pixel defining layer, and the pixel defining layer defines aplurality of pixel units which are arranged at intervals; the light emitting device layer is disposed on the pixel defining layer of the circuit driving layer; the packaging layer is arranged on the light emitting device layer and blocks the pixel units; and the organic filling layer covers the packaging layer and is used for spacing the pixel units, and part of the substrate is selectively exposed to the organic filling layer. According to the flexible display panel, the grooves are formed in the flexible display panel, film layers in the bending area of the edge of the panel are reduced, thegrooves are filled with organic materials with small rigidity and high elasticity to form the organic filling layer, the purpose of improving the bending performance of the bending area is achieved,bending stress is relieved, cracks are reduced, the product quality is improved, and the service life is prolonged.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a flexible display panel applied to a curved display screen and a preparation method thereof. Background technique [0002] Organic light emitting diode (OLED) devices have the advantages of simple structure, fast response, active light emission, low power consumption, etc., and have been widely used in display fields such as mobile phones, tablets, and televisions. Curve Diaplay refers to a display device with a curved panel, which is the current mainstream direction in the mobile phone industry. The slightly curved edge of this display can be close to the user, and achieve the same viewing angle as the center of the screen, which can be extended The user's field of vision allows them to experience a better viewing effect. [0003] However, the edge of the curved screen will be bent, and the high-strength and long-term bending stress will cause intralayer cracks or interlayer ...
