Abstract

The present invention provides a quantum light emitting diode (LED) and a display device. The quantum LED includes a first electron layer, an organic light emitting layer, a first hole layer, a secondelectron layer, a quantum dot light emitting layer and a second hole Layer. All of the above layers are successively arranged in a laminating manner. The first electron layer is used to transmit a first electron to the organic light emitting layer. The first hole layer is used to transport a first hole to the organic light emitting layer. The organic light emitting layer is used to recombine thefirst electron and the first hole to emit first light. The second electron layer is used to transmit a second electron to the quantum dot light emitting layer. The second hole layer is used to transport a second hole to the quantum dot light emitting layer. The quantum dot light emitting layer is used to recombine the second electron and the second hole to emit second light. In the scheme, the organic light emitting layer and the quantum dot light emitting layer are provided and the two electron layers and the two hole layers that respectively transmit the electrons and the holes to the organic light emitting layer and the quantum dot light emitting layer are provided, so that the lifetime of the quantum light emitting diode (LED) is increased.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a quantum light emitting diode and a display device. Background technique [0002] Since the luminescence wavelength of quantum dot materials can change with the size of the material, and they have the advantages of wide excitation spectrum, high electron mobility, and high light purity, they are widely used in display devices. [0003] Quantum dot backlight (Quantum Dot Liquid crystal display, QD-LCD) technology applies quantum dot material to LCD (Liquid crystal display) backlight. Quantum dots themselves have luminous properties, and will generate red light (Red, R) and green light (Green, G) under the illumination of a blue LED backlight, and mix with the blue light (Blue, B) that partially passes through the film to obtain white light , thereby improving the luminous effect of the entire LCD backlight. [0004] QD-LCD technology only improves the backlighting effect of LC...
