Abstract

A quantum dot film and a light-emitting module. The quantum dot film comprises a quantum dot material layer (22) and a light control film (24). The light control film (24) is used for reflecting an incident light of which the incident angle falls in a preset range and transmitting an incident light of which the incident angle falls out of the preset range. The incident lights entering the quantum dot material layer (22) are approximately equal in energy. The colors of excited lights of the quantum dot material layer (22) are approximately a same color.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a quantum dot film and a light emitting module. Background technique [0002] One of the known methods for generating white light from a light emitting diode (LED) light-emitting device is to use a thin film containing quantum dots (QD, Quantum Dot) as the light-emitting layer of the light-emitting diode, and pass quantum dots of different materials or particle sizes It is obtained by mixing light after being irradiated by the excitation light source and emitting secondary light with a wavelength different from that of the excitation light source. For example, a blue LED can be used as an excitation light source, and quantum dot materials with different particle sizes can be excited to generate red light and green light, so that red light, green light and blue light can be mixed to form white light. [0003] The above-mentioned light-emitting device containing qua...
