Abstract

The present invention provides a display panel and a display device for improving the COG mura phenomenon of the display panel caused by IC bonding in the prior art. The display panel includes an array substrate and a color filter substrate arranged oppositely, at least one integrated circuit, and several retaining walls; the display panel includes a display area and a non-display area arranged around the display area; the integrated circuit is arranged on the array The substrate faces the side of the color filter substrate and is located in the non-display area; the blocking wall is arranged between the array substrate and the color filter substrate, and is located between the display area and the integrated circuit In the non-display area between; the distribution density of the retaining wall within the preset range of the top of the integrated circuit is greater than the distribution density of the retaining wall at other positions, wherein the top is the integrated circuit At the top in the first direction, the first direction is perpendicular to the direction in which the integrated circuit points to the display area.

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] In the existing display panels, the integrated circuit (IC) is generally packaged by using COG (chip on glass) technology, which specifically refers to using anisotropic conductive film (Anisotropic ConductiveFilm, ACF) to directly connect the pins of the integrated circuit to the The electrode terminals of the glass substrate are face-to-face crimped and connected, and its laminated structure is as follows: figure 1 As shown, there are glass substrate 11 , ACF 12 and integrated circuit 13 from bottom to top. [0003] In practical applications, it is found that after the integrated circuit is bound on the glass substrate based on COG technology, the glass substrate will be warped and deformed. figure 2 is a schematic structural diagram of a display panel in the prior art, image 3 for along figure ...
