Embodiment Construction

[0026] In order to make the above objects, features and advantages of the present invention more comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described here, and those skilled in the art can make similar improvements without departing from the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0027] It should be noted that when an element is referred to as being “formed on” another element, it may be directly formed on the other element or there may be an intervening element. The terms "upper", "lower" and similar expressions used herein are for the purpose of illustration onl...

Abstract

The present invention relates to a display panel and a display device. Provided is a display panel, comprising an array substrate, and a light emitting structure arranged on the array substrate, the light emitting structure comprising a first electrode, an organic light emitting layer and a second electrode stacked on the array substrate. The organic light emitting layer includes pixels, and a pixel defining layer disposed between adjacent pixels. The light emitting structure further includes a plurality of first support columns and a plurality of second support columns, the first support columns disposed between the pixel defining layer and the second electrode. A second support column is disposed on a side of the second electrode remote from the pixel defining layer. The projections of the first support column and the second support column with respect to the array substrate do not overlap and are both located above the pixel defining layer. As that display panel comprises a plurality of first support columns and a plurality of second support columns, when the display panel is impacted, stress can be more evenly absorbed and release, the risk of component damage can be reduced, and the purpose of improving the impact resistance and the display failure can be achieved.

Description

technical field [0001] The invention relates to display technology, in particular to a display panel and a display device. Background technique [0002] Organic light-emitting diode (Organic Light-Emitting Diode, OLED) display, also known as organic electroluminescent display, is a new type of flat panel display device, due to its simple preparation process, low cost, low power consumption, high luminance, It has the advantages of light and thin volume, fast response speed, and easy realization of color display, large-screen display, and flexible display, etc., and has broad application prospects. [0003] After the organic light-emitting diode display is manufactured, a series of reliability tests of the display panel are usually required, and a ball drop test is usually used to test the impact resistance of the screen. The inventors found that when the display panel is hit by a falling ball, there will be display defects such as black spots, bright spots, colorful spots, ...
