Abstract

The invention discloses a light emitting diode, an encapsulation structure thereof, an encapsulation method thereof and a display device. A problem in the prior art is solved that a light emitting diode of current encapsulation structure will filter blue light except for high-energy shot-wave blue light which is harmful to human health, so color range of the light source of the light emitting diode is reduced and display effects are affected. The encapsulation structure comprises a substrate base plate, a blue light emitting diode device formed on the substrate base plate, a protective layer covering the blue light emitting diode device and an encapsulation cover plate which is arranged on a light filtering layer on the protective layer and covers the light filtering layer. The light filtering layer comprises a carrier formed by transparent resin and semiconductor particles which are doped in fluorescence particles used for light excitation in the carrier and are used for filtering the high-energy shot-wave blue light. The fluorescence particles are fluorescence particles coated or modified by silicon dioxide. The semiconductor particles are semiconductor nano-particles coated or modified by silicon dioxide.

Description

technical field [0001] The present invention relates to the field of display technology, and in particular, to a light emitting diode and its packaging structure, packaging method and display device. Background technique [0002] Thin-Film Transistor Liquid Crystal Display (TFT-LCD) technology has been widely used. A TFT-LCD display usually includes a liquid crystal panel and a backlight module. As the main component of the TFT-LCD display, the backlight module has developed rapidly in recent years, and the traditional cold cathode has been gradually replaced by the Light Emitting Diode (LED) light source. Fluorescent tube (Cold Cathode Fluorescent Lamp, CCFL) light source. [0003] LED light source has the advantages of uniform light emission, high brightness, energy saving and environmental protection. The LED light source is composed of a plurality of encapsulated LEDs. The existing LED encapsulation structure includes an LED device formed on a base substrate, a protect...
