Abstract
The present application provides a display panel, a preparation method thereof, and a display device. The display panel includes a display area and a non-display area extending around the display area. The display panel includes: a substrate; an array structure layer, which is arranged on the substrate, a drive circuit is arranged in the array structure layer, and the array structure layer includes a first part and an array structure layer. The second part, the first part is the projection part of the display area on the array structure layer, the second part is the projection part of the non-display area on the array structure layer, wherein the second part is provided with a groove filled with the first organic material; a planarization layer, the organic planarization layer covers the first part and includes a first organic material; the light-emitting device layer is disposed on the organic planarization layer, the light-emitting device layer corresponds to the display area and is electrically connected with the driving circuit; packaging layer, the encapsulation layer covers the light emitting device layer and extends to the second part. The above technical solution can improve the black spot problem generated at the edge of the display panel and prolong the service life of the display panel.
Description
technical field [0001] The present application relates to the field of display technology, and more particularly, to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] Organic light emitting diode (OLED) display panels are widely used in display devices such as mobile phones, televisions, and flat panels due to their advantages of being thin and light, high in brightness, fast in response, good in flexibility, and high in luminous efficiency. However, OLEDs are sensitive to water vapor and oxygen. If the device packaging performance is not good enough to cause water and oxygen to invade, the water vapor and oxygen intruding into the display panel will have an effect on the organic electroluminescent (EL) material in the OLED device, making organic The EL material changes and cannot emit light, that is, the problem of dark spots occurs. [0003] After some black spots are formed, they will gradually become larger with time, w...
