Abstract

The invention belongs to the technical field of display, and particularly relates to a flexible OLED display panel with a fluorescent light-emitting layer. The buffer layer is prepared on the flexible substrate; the thin film transistor layer is prepared on the buffer layer; the fluorescent light-emitting layer is prepared on the thin film transistor layer; the heat dissipation layer is prepared on the side face of the periphery of the fluorescent light-emitting layer, a plurality of heat dissipation through holes which are evenly distributed are formed in the heat dissipation layer, and the two sides of each heat dissipation through hole are evenly and equivalently filled with a plurality of first silicone grease particles respectively; the first packaging layer is prepared on the fluorescent light-emitting layer, and the first packaging layer covers the surface of the fluorescent light-emitting layer and the surface of the heat dissipation layer; according to the OLED display panel, the problems that the OLED display panel generates much heat and is poor in heat dissipation are solved, and the service life of the OLED display panel is prolonged.

Description

technical field [0001] The invention belongs to the field of display technology, in particular to a flexible OLED display panel with a fluorescent light-emitting layer. Background technique [0002] Compared with many displays, OLED display panels have many advantages such as active light emission, high contrast ratio, and no viewing angle limitation, especially flexible OLED display panels, which have more obvious advantages. The flexible OLED display panel is not only thinner and lighter in size, but also lower in power consumption than the original device, which helps to improve the battery life of the device. At the same time, based on its bendable and flexible characteristics, its durability is also much higher than before. screen, reducing the probability of accidental damage to equipment. Therefore, flexible OLED display panels have been widely used in the field of display technology and will become the mainstream of OLED display consumption in the future. However, ...
