Problems solved by technology

[0004] However, with the design of the prior art, the bending protrusion of the COF after bending is relatively large, resulting in the size of the frame area of ​​the display panel is still large, and the improvement of the screen ratio of the display panel is limited.

Abstract

Embodiments of the present invention provide a display panel and a display device, which relate to the field of display technology and are used to reduce the frame width of the display panel and realize the narrow frame design of the display panel. The display panel includes a rigid substrate, the rigid substrate includes a first surface and a second surface; the first surface includes a plurality of connecting pins; a flexible circuit board; the flexible circuit board includes a first flat part, a bent part and a second flat part , wherein the bent portion is located between the first flat portion and the second flat portion, the first flat portion is in contact with the first surface, the bent portion is attached to the second surface, and the second flat portion is bent to The rigid substrate is away from the side of the first surface, and the first flat part is electrically connected to the connecting pin; the second flat part includes a driving circuit; the driving circuit is connected to the connecting pin through a flexible circuit board; the first surface and the second Corners between surfaces are fillets or chamfers.

Description

【Technical field】 [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. 【Background technique】 [0002] At present, with the continuous development of display technology, the requirement for the appearance size of the display screen is getting higher and higher. Especially for mobile display products such as mobile phones, it is more required to have a display effect with narrow borders and high screen-to-body ratio, that is, it is expected that the size of the non-display area around the display area of ​​the display panel will be smaller and smaller. [0003] In order to increase the screen-to-body ratio of the display panel, the driver chip that drives the display panel for display is usually bound to a flexible printed circuit (FPC) (hereinafter referred to as FPC), that is, Chip On Film (Chip On Film, hereinafter referred to as COF) technology, and then bend the COF to the backlight side of the d...
