Problems solved by technology

Generally, in flexible OLED display panels, the anode in the OLED device is usually composed of transparent conductive oxides such as indium tin oxide (ITO), and the flexibility of these conductive oxide films is compared to other organic film layers in the OLED device. It should be low, so that cracks are more likely to occur at the anode when the OLED device is bent by external force, which will cause the brightness of the display pixel composed of the OLED device to decrease or even fail.

Abstract

The invention discloses an OLED device, which comprises: a flexible substrate (110); a first anode (150A) and a second anode (150B) on the flexible substrate (110); wherein, the first anode (150A) and the second anode Two anodes (150B) are spaced apart from each other to form a channel; a flexible conductive component in the channel; wherein the flexible conductive component is respectively connected to the first anode (150A) and the second anode (150B); on the first anode (150A) The first organic light emitting layer (180A) and the second organic light emitting layer (180B) on the second anode (150B); the cathode on the first organic light emitting layer (180A) and the second organic light emitting layer (180B) ( 190). The invention improves the flexibility of the anode of the OLED device, and at the same time reduces the actual continuous length of the anode in the bending direction, reduces the probability of cracks in the OLED device during the external force bending process, thereby improving the OLED device formed. Bendable, wearable capabilities of flexible OLED displays.

Description

technical field [0001] The invention belongs to the technical field of semiconductors, and in particular relates to an OLED (organic light emitting diode) device, a manufacturing method thereof, and a flexible display unit. Background technique [0002] In the flexible display technology, how to improve the flexibility of each part of the flexible display device, so as to avoid the failure of a certain part of the flexible display device due to cracking or irreversible deformation in the process of bending, winding and extrusion , is the prerequisite to ensure the successful application of flexible display devices. [0003] Especially in the flexible OLED display panel, one of the key points is to prevent some rigid layers in the flexible OLED display panel from cracking (Crack) caused by uneven stress when the bending radius of curvature is too large. Generally, in a flexible OLED display panel, the anode in the OLED device is usually composed of transparent conductive oxi...
