Abstract

The invention discloses a display panel and a display device. The display panel includes: a base substrate, a cathode layer located on the base substrate, a plurality of first support columns supported between the base substrate and the cathode layer, and A plurality of second supporting pillars, a packaging cover plate located on the side of the cathode layer away from the base substrate, and a touch electrode layer located between the package cover plate and the cathode layer; wherein, the touch electrode layer includes: a plurality of touch electrodes Electrode; the orthographic projection of the first support column on the base substrate and the orthographic projection of the touch electrode on the base substrate have an overlapping area, and the orthographic projection of the second support column on the base substrate and the touch electrode on the substrate Orthographic projections on the substrate have no overlapping areas. By arranging two types of support columns between the base substrate and the cathode layer, the types of support columns are increased, so that support columns can be provided at more positions, increasing the density of support columns, and will not affect the touch electrodes The performance can effectively enhance the mechanical strength of the display panel.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] Organic Light-Emitting Diode (OLED) display devices have many advantages, such as flexible and bendable, light and thin, wider viewing angle, bright colors, no need for backlight, and energy saving, and have broad application prospects. [0003] At present, in the in-cell touch panel, in order to reduce the coupling capacitance between the touch trace and the cathode, and enhance the touch performance of the touch trace, the touch trace needs to comprehensively consider the opening of the pixel definition layer and the support column. Position, in order to ensure better touch performance, it is necessary to set as many touch traces as possible, so that the density of the support columns is extremely low, resulting in poor mechanical strength of the display panel.
