Abstract

The invention relates to the technical field of LED backlight source arrangement, and provides a full-spectrum LED backlight source packaging structure for an LCD liquid crystal screen and a preparation method of the full-spectrum LED backlight source packaging structure. The packaging structure comprises a substrate; the at least one LED chip is arranged on the substrate; a light source covering the full-spectrum band of natural light can be generated based on the at least one LED chip. According to the embodiment of the invention, the LED chip or the fluorescent powder capable of covering the full spectrum of the natural light is arranged, so that the spectrogram finally displayed by the LCD screen is closer to the full spectrum of the natural light, the spectral band is more complete, the harm of blue light is reduced, and the vision health and vision development of people and teenagers are better protected.

Description

technical field [0001] The present disclosure relates to the technical field of LED backlight light source arrangement, and in particular, to a full-spectrum LED backlight light source for LCD liquid crystal screens, a preparation method and a display device. Background technique [0002] With the development of the Internet market economy and the global epidemic, people's demand for LCD screens is increasing, and more teachers and students have joined the online teaching mode. People have begun to pay attention to the light hazards caused by LCD screens to vision. The backlight sources used in the LCD screen are all common three-color LED light sources on the market, which cannot cover the full spectrum of natural light, resulting in problems such as high blue light hazard, color cast, and uneven spectral distribution on the LCD screen, which seriously affects the eyesight health of people and young people. Vision development. SUMMARY OF THE INVENTION [0003] In view of...
