Abstract

The embodiment of the invention provides a display device light source module for promoting growth and repair of retinal cells and visual neurons, a display screen and application. The module comprises a light source capable of emitting visible light with the spectral wavelength of 400 to 700nm and far-red light with the wavelength of 650 to 900nm. The light source in the light source module can emit far-red light with the wavelength of 650 to 900nm; and the far-red light with the wavelength has a promotion effect on growth and repair of retinal cells and visual neurons. According to the embodiment of the invention, a technical problem that damaged retinal cells and visual neurons cannot be repaired in the prior art is solved. Therefore, the damages of a liquid crystal display television with an LED as a backlight source and other electronic display screens with LEDs emitting light actively or passively as light sources on vision health of human eyes can be reduced, the vision is improved, and the eye health is improved. The invention provides a solution for developing a vision health liquid crystal television and a display screen.

Description

technical field [0001] The invention relates to a display light source module, and more particularly to a display light source module, display screen and application for promoting the growth and repair of retinal cells and optic neurons. Background technique [0002] Since entering the Internet + era, the information and information transmitted by various electronic screens such as smartphones, car displays, LCD TVs, and large-screen displays have brought great convenience to our lives and significantly improved our quality of life. . At present, among all kinds of electronic screens, liquid crystal displays have the largest number of users and the highest market share. However, liquid crystals cannot actively emit light and require a backlight source. Early liquid crystal displays used cold cathode ray tubes as backlight sources, but cold cathode ray tubes had high voltage and high energy consumption, and were gradually replaced by LEDs (Light Emitting Diodes, light emitti...
