The embodiment of the present invention discloses a flexible display substrate, a flexible display panel, and a flexible display device, wherein the flexible display substrate includes a display area and a peripheral circuit area, and the peripheral circuit area includes a bend located on one side of the display area. The folding area also includes: a base substrate; a plurality of signal transmission lines formed on the base substrate, in the bending area, at least two of the signal transmission lines are electrically connected to form a signal transmission unit, each of the signal transmission lines The transmission unit includes at least a first signal transmission line and a second signal transmission line, and a first through hole is formed on the first signal transmission line, and a second through hole is formed on the second signal transmission line. With the above technical solution, at least two signal transmission lines are electrically connected to form a signal transmission unit, and each signal transmission line is formed with a through hole to ensure that the signal transmission unit is not prone to breakage in the bending area and that the flexible display substrate can be displayed normally.
Description
technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a flexible display substrate, a flexible display panel, and a flexible display device. Background technique [0002] As a new generation of display devices, flexible displays are widely used in mobile phones, personal digital assistants (PDAs), digital cameras, vehicle displays, Notebook computers, wall-mounted TVs, and military fields have very broad application prospects. [0003] In existing flexible displays, in order to increase the screen-to-body ratio of the display area and reduce the edge width below the display area, the flexible substrate is bent to the back of the display area. However, when the lower edge of the display area is bent to the back of the display area, it will also cause bending and stretching of the metal wiring, and the metal wiring is prone to breakage in the bending area, which affects the normal display of the flexible d...
