Abstract

The invention provides an OLED display panel and a display device. A test area of the OLED display panel comprises a substrate, an inorganic film layer, a planarization layer, a pixel definition layerand a packaging layer which are laminated, wherein the planarization layer is provided with a through hole at a pixel opening position corresponding to the pixel definition layer, and the packaging layer is deposited in the pixel opening and the through hole; and the planarization layer is separated from each other to form a new water blocking area and the packaging effect is enhanced.

Description

technical field [0001] The disclosure relates to the field of display technology, and in particular to an OLED display panel and a display device. Background technique [0002] For the technology of making OLED light-emitting devices by inkjet printing (Ink Jet Printing, IJP) process, since the film thickness at the edge of the light-emitting area is different from the film thickness at the center of the light-emitting area during printing, it is necessary to print an additional test area to ensure effective The uniformity of film thickness in the light-emitting area. However, the test area is composed of organic materials such as pixel definition layer and planarization layer, and the test area is inside the encapsulation area and close to the edge of the encapsulation area. Due to the poor water resistance of organic materials, water vapor is more likely to invade the OLED light-emitting device through the test area. [0003] The bottom of the existing test area is an ino...
