Description

technical field

[0001] The invention relates to the fields of light emission and light diffusion, in particular to a quantum dot film with a multilayer structure, which is used as a light diffusion film and a high-end fluorescent material for illumination and display. Background technique

[0002] Liquid crystal displays are used in personal computers, televisions, monitors, cell phones, personal digital assistants, game consoles, e-readers, digital cameras, and similar products. Traditionally, the backlight module is combined with a liquid crystal unit to convert white light into the desired color light. The color light emitted by this traditional light emitting device has limited performance and low luminous efficiency. Therefore, it is very necessary to develop low-cost light-emitting methods and devices to obtain colored light with high purity, high efficiency, and improved performance. The multi-layer quantum dot film of the present invention is sandwiched into the ba...
