Abstract

The invention discloses a LED light source structure. The light source structure comprises a fixing support, a LED chip, a packaging glue and a quantum dot glass box. The fixing support is successively provided with a packaging groove and an installation groove from a bottom portion to a top portion. A width of the installation groove is larger than a width of the packaging groove. The LED chip is packaged into the packaging groove by using the packaging glue. The installation groove possesses a size which matches with a size of the quantum dot glass box. The quantum dot glass box is clamped and placed in the installation groove. The quantum dot glass box comprises a glass box and a quantum dot phosphor powder material. The glass box possesses an accommodation cavity. The quantum dot phosphor powder material is packaged into the accommodation cavity in a solidification mode. The invention also discloses a packaging method of the LED light source structure.

Description

technical field [0001] The invention relates to the technical field of backlight modules in liquid crystal displays, in particular to an LED light source structure using quantum dot (QuantumDots, QD) technology and a packaging method thereof. Background technique [0002] Liquid crystal display (LCD) has the advantages of thin body, low power consumption, and no radiation, and has been widely used, such as mobile phones, digital cameras, computers, TV screens, and the like. Most of the liquid crystal displays on the market are backlight liquid crystal displays, including a liquid crystal panel and a backlight module. The liquid crystal panel and the backlight module are arranged opposite to each other. With the development of society, users have higher and higher requirements for the quality of the LCD display screen. In order to improve the color saturation of the screen, the color saturation of the screen can be improved by improving the color saturation of the light bar i...
