Abstract
The invention provides a flexible LED device, a manufacturing method thereof and a display device. The flexible LED device comprises a flexible substrate, a plurality of LED chips which are arranged on the flexible substrate in an array form, and a flexible heat dissipation module which is arranged on the flexible substrate and around each LED chip, the flexible heat dissipation module comprises a protruding part, and the protruding part is internally provided with a heat dissipation channel leading to the outside of the flexible LED device; the flexible LED device further comprises a color conversion module corresponding to the plurality of LED chips, and a flexible packaging module which is arranged on the flexible heat dissipation module and the color conversion module. According to the technical scheme, heat generated by the LED chips can be directly discharged out of the flexible LED device through the heat dissipation channel of the flexible heat dissipation module, and therefore the heat dissipation performance of the flexible LED device is enhanced.
Description
technical field [0001] The present disclosure relates to the technical field of semiconductor LEDs, and in particular, to a flexible LED device, a manufacturing method thereof, and a display device. Background technique [0002] In recent years, with the development of process technology and the improvement of application requirements, flexibility, miniaturization, arrayization, and integration have become the research trend of LED devices, which can be applied to non-planar working environments, and have the characteristics of bending and extensibility. Flexible LED devices have been developed rapidly, which greatly expands the application range compared with traditional LED devices. [0003] However, as an optoelectronic device, LED flexible devices will generate a lot of heat during use. If the heat cannot be discharged in time, it will seriously affect the photoelectric color performance and reliability of the device. At present, although there are many heat dissipatio...
