Description

technical field

[0001] The invention relates to a novel top-emitting light-emitting device, in particular to an organic / polymer top-emitting light-emitting device and its application. Background technique

[0002] In 1990, the research team of the University of Cambridge first made the first polymer light-emitting device with a conjugated structure PPV polymer material as the light-emitting layer. Because light-emitting polymer devices have outstanding advantages such as low material cost, easy large-area molding, low driving voltage, low energy consumption, and luminescent wavelength can be tuned through material structure, it is considered possible to be applied in large-area flat-panel TVs.

[0003] With the progress of global organic / polymer light-emitting devices in the process of flat-panel display applications, the development of high-efficiency top-emitting light-emitting devices has become one of the urgent research topics. Because compared...
