Abstract

The invention provides a flexible OLED (Organic Light Emitting Diode) display panel and a production method thereof. A FS (Flexible Substrate) in the flexible OLED display panel comprises a patternedfirst flexible layer (2), a separation layer (3) covering the patterned first flexible layer (2) in a full-surface mode, and a patterned second flexible layer (4) arranged on the separation layer (3).When the flexible OLED display panel is bent, a bending stress is released through a plurality of first grooves (21) of the patterned first flexible layer (2) and a plurality of second grooves (41) of the patterned second flexible layer (4), so that bendability of the flexible OLED display panel can be reinforced, breakage of the flexible OLED display panel in the bending process is prevented, and yield of the flexible OLED display panel product is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a flexible OLED display panel and a manufacturing method thereof. Background technique [0002] In the field of display technology, flat panel display devices such as Liquid Crystal Display (LCD) and Organic Light Emitting Diode (OLED) have gradually replaced Cathode Ray Tube (CRT) displays. [0003] Among them, the OLED display panel has many advantages such as self-illumination, low driving voltage, high luminous efficiency, short response time, high definition and contrast, nearly 180° viewing angle, wide operating temperature range, flexible display and large-area full-color display, etc. , is recognized by the industry as the most promising display device. [0004] see figure 1 The existing flexible OLED display panel generally includes a glass substrate 100, a first flexible layer 200 covering the entire surface of the glass substrate 100, a spacer layer 300 covering the...
