Abstract

The invention discloses a quantum dot backlight source and a liquid crystal display with the same. The quantum dot backlight source comprises a backboard, a light source component, a light guide plate, a quantum rod and a mounting seat, the light source component is arranged in the backboard, the light guide plate is arranged in the backboard, positioned on one side of the light source component and used for receiving light rays of the light source component, the quantum rod is arranged between the light source component and the light guide plate, separated from the light source component andthe light guide plate and used for transforming colors of the light rays of the light source component, the mounting seat is arranged in the backboard and positioned below the quantum rod and the light guide plate, and the quantum rod and the light guide plate are oppositely and fixedly mounted on the mounting seat. The quantum dot backlight source can solve the problem that quantum dot materialsleak as the quantum rod is cracked when the quantum rod is extruded by the light guide plate in expansion, use reliability of the quantum dot backlight source is improved, and the quantum dot backlight source is safer and more environmentally friendly.

Description

technical field [0001] The invention relates to a backlight source, in particular to a quantum dot backlight source and a liquid crystal display screen with it. Background technique [0002] A backlight module is one of the key components of a liquid crystal display (LCD). Currently, liquid crystal displays (LCDs) have been widely used in portable electronic products with high growth potential such as mobile phones, notebook computers, and digital cameras. [0003] Quantum dots can be used to increase color purity in LED light sources. When excited electrons are transferred from the conduction band to the valence band, the quantum dots emit light, and the wavelength of the light changes according to the size of the quantum dots. Since light of a shorter wavelength is emitted when the size of the quantum dot is small, light having a desired wavelength can be obtained by adjusting the size of the quantum dot. [0004] The quantum dot material may contain dangerous component...
