Embodiment 1

[0027] Please refer to figure 1 , the present embodiment provides an OLED display panel, including a base substrate 1, an organic electroluminescent unit 2 disposed on the base substrate 1, an organic layer 3 disposed on the base substrate 1 and covering the organic electroluminescent unit 2 , the packaging cover plate 4 located on the side of the organic layer 3 away from the base substrate 1 and connected to the base substrate 1; wherein:

[0028] The organic layer 3 includes organic material and metal nitride capable of releasing ammonia gas by reacting with water.

[0029] In the above-mentioned OLED display panel, the OLED display panel includes a base substrate 1, an organic electroluminescent unit 2, an organic layer 3, and an encapsulation cover plate located on the side of the organic layer 3 away from the base substrate 1 and connected to the base substrate 1 4. Since the organic electroluminescent unit 2 is placed on the base substrate 1, and the organic layer 3 i...

Embodiment 2

[0046] Please refer to figure 2 A silicon nitride layer 6 is also provided between the organic layer 3 and the organic electroluminescent unit 2 , and the silicon nitride layer 6 is used to isolate the gas from the organic electroluminescent unit 2 .

[0047] It should be noted that the silicon nitride layer 6 isolates the organic electroluminescent unit 2 from other substances, avoids contact with water and oxygen, and better prolongs the service life of the organic electroluminescent unit 2 .

[0048] On the basis of Embodiment 1 and Embodiment 2, the OLED display panel further includes a light-shielding layer 7 disposed on the side of the packaging cover plate 4 facing the base substrate 1 .

[0049] Specifically, the light-shielding layer 7 is disposed on the side of the packaging cover plate 4 facing the base substrate 1 , so that the orthographic projection of the light-shielding layer 7 on the base substrate 1 is located in the area where the organic electroluminescent...

Embodiment 3

[0053] Please refer to image 3 The side of the organic layer 3 away from the base substrate 1 is also provided with a metal layer 8 capable of forming a dense oxide film when oxidized by oxygen.

[0054] It should be noted that, on the one hand, the metal layer 8 can play the role of covering the middle display layer of the organic electroluminescence unit 2 when the encapsulation glue 9 is sealed and cured; on the other hand, it can also form a dense oxide when the metal is oxidized by oxygen. Thin film, which forms the protection of the organic layer 3, prolongs the time when the oxygen and water in the gas entering the closed cavity contact the organic layer 3, starts to act on the organic layer 3, and slows down the diffusion of oxygen and water to the organic electroluminescence unit 2, prolonging the service life of the organic electroluminescence unit 2.

[0055] On the basis of the technical solution in the third embodiment above, the metal layer 8 is a non-transpare...

Abstract

The invention relates to the field of display technology, and discloses an OLED display panel and a display. The OLED display panel includes a base substrate, an organic electroluminescence unit arranged on the base substrate, an organic electroluminescent unit arranged on the base substrate and covered with an organic electroluminescence unit. The organic layer of the unit, the encapsulation cover plate located on the side of the organic layer away from the base substrate and connected to the base substrate box; wherein: the organic layer includes organic materials and metal nitrides that can react with water to release ammonia gas. The above-mentioned OLED display panel uses an organic layer to absorb the water carried in the gas entering the OLED display panel, so as to delay the aging rate of the organic electroluminescent unit and prolong the life of the organic electroluminescent unit.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an OLED display panel and a display. Background technique [0002] In recent years, an organic electroluminescent display panel (Organic Light-Emitting Diode, OLED), which is an emerging display technology, has gradually emerged due to its own advantages. In summary, its advantages are roughly as follows: 1. OLED is a solid-state mechanism, there is no liquid substance inside, and the shock resistance is better, and it is not afraid of being beaten; 2. The viewing angle is large, and the picture is still not distorted even under a large viewing angle; 3. The response of OLED The time is one-thousandth of that of LCD, and there is no smear phenomenon in displaying moving pictures; 4. Good low-temperature characteristics, it can still display normally at minus 40 degrees; 5. Self-luminous light, no loss of light efficiency, and lower energy consumption; 6. The black state is dark...
