Embodiment Construction

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0023] figure 1 It is a structural schematic diagram of an organic light-emitting display panel in the prior art, such as figure 1 As shown, the organic light-emitting display panel includes a display area AA' and a non-display area AB', and also includes: a thin film encapsulation layer 70', the thin film encapsulation layer 70' includes an organic layer 71' and an inorganic layer 72', at least two The barrier unit 80', because the material of the organic layer 71' has fluidity, causes it to extend to the non-di...

Abstract

The invention discloses an organic light-emitting display panel and a device. The organic light emitting display panel includes a display area and a non-display area surrounding the display area; the organic light emitting display panel also includes: a base substrate; a thin film encapsulation layer, the thin film encapsulation layer is located on one side of the base substrate, and the thin film encapsulation layer covers the display area , and extend to a part of the non-display area; wherein, the thin film encapsulation layer includes at least one organic layer and at least one inorganic layer, the organic layer is located between the base substrate and the at least one inorganic layer, and an organic layer close to the base substrate includes at least one The lower surface of the organic layer on the side of the base substrate, along the direction away from the display area, the vertical distance from the lower surface of the organic layer to the surface of the base substrate on the side of the base substrate close to the thin film encapsulation layer gradually decreases. The organic light-emitting display panel provided by the embodiments of the present invention is beneficial to the narrow frame of the organic light-emitting display panel; at the same time, the flow speed of the organic layer material is accelerated, and the time for the organic layer to be cut off early is reduced.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technologies, and in particular to an organic light emitting display panel and a device. Background technique [0002] Organic light-emitting display panels are widely used in various high-performance display fields due to their advantages of high brightness, low power consumption, wide viewing angle, high response speed, and wide operating temperature range. [0003] However, water vapor and oxygen in the surrounding environment seriously affect the lifetime of the OLED panel. In the prior art, a method of thin film encapsulation is often used to ensure that the organic light-emitting materials and electrodes in the organic light-emitting display panel are not corroded by water vapor and oxygen in the external environment. However, the extension effect of the organic film layer in the thin film packaging will lead to an increase in the frame size of the organic light emitting display...
