Abstract

The invention discloses a flexible display panel and a rollable display device. The flexible display panel comprises: a substrate which comprises a display region; a pixel circuit arranged on the substrate and located in the display region; and a first via hole formed in the display region, wherein at least one first via hole is arranged between two adjacent pixel circuits. According to the flexible display panel and the display device, the first via holes are formed between every two adjacent pixel circuits in the display region of the substrate, when the flexible display panel is bent or rolled, stress is concentrated in the first via holes, and the situation that the flexible display panel is folded or damaged due to stress concentration is avoided; and meanwhile, a plurality of secondvia holes are formed in the non-display region at intervals in a staggered manner, so that the stress of the non-display region can be further released, the dynamic stretching and bending durability of the flexible display panel and the performance durability and functional reliability of the rollable display device are improved, and the product quality and the production yield are improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a flexible display panel and a rollable display device. 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] The LCD display device is composed of a thin film transistor array substrate (Thin Film Transistor Array Substrate, TFT Array Substrate) and a color filter (Color Filter, CF) substrate, and liquid crystal is poured between the TFT substrate and the CF substrate. , through electrification or not to control the liquid crystal molecules to change direction, and refract the light from the backlight module to produce a picture. [0004] OLED has many advantages such as self-illumination, low driving voltage, high luminous efficiency, short response time, high definition and contrast, nearly 180° ...
