Problems solved by technology
[0003] However, in the actual operation process, the distance between the storage tank and the contact hole of the OLED is relatively short. During the process of printing the organic light-emitting material on the storage tank, the organic light-emitting material is easy to overflow out of the storage tank and overflow into the contact hole. , resulting in poor contact between the organic light emitting diode and the pixel circuit, affecting the normal display of the organic light emitting diode

The invention discloses an organic light-emitting diode, an OLED display panel and a display device. The organic light-emitting diode comprises a storage tank layer, the storage tank layer is providedwith a contact hole and a plurality of storage tanks, the storage tanks and the contact hole are arranged at intervals, the storage tanks and the contact hole penetrate the storage tank layer, and the storage tanks are filled with organic light emitting materials, wherein the contact hole is provided with a first position point, the minimum distance between the first position point and the wall surfaces of the storage tanks is a first distance, the minimum distance between other positions of the contact hole and the wall surfaces of the storage tanks is a second distance, the first distance is smaller than the second distance, and when the contact hole is a polyhedron, the first position point is far away from the edge of the contact hole. Under the condition that the distance between thestorage tanks and the center of the contact hole is the same, the minimum distance between the storage tanks and the contact hole is increased, so that the organic light-emitting materials in the storage tanks are prevented from overflowing into the contact hole, and the normal display of the organic light-emitting diode is ensured; and meanwhile, the volumes of the storage tanks can be increased, and the aperture opening ratio of the organic light-emitting diode is increased.
Description
technical field [0001] The present application relates to the display field, in particular to an organic light emitting diode, an OLED display panel and a display device. Background technique [0002] With the advancement of technology, organic light-emitting diodes (Organic Light-Emitting Diode, OLED for short) are more and more applied to the display field. The storage tank layer of the organic light-emitting diode is provided with a contact hole and a storage tank, and the organic light-emitting material is printed into the storage tank by an inkjet printing process, and the contact hole is used to connect the organic light-emitting diode and the bottom of the organic light-emitting diode for A pixel circuit that controls the light emitted by an organic light-emitting diode. [0003] However, in the actual operation process, the distance between the storage tank and the contact hole of the OLED is relatively short. During the process of printing the organic light-emittin...
