Smoothing structure applied to LED and LED display screen

Abstract

The embodiment of the invention discloses a smoothing structure applied to an LED and an LED display screen. The technical problems that vision is hurt by output LED light due to the fact that the optical wavelength of the LED light is single and the spectral energy of the short wavelength is very high are solved by adjusting the coupling area to control the smoothing rate of the LED light. The smoothing structure comprises a waveguide and a resonator, the waveguide comprises an input end and an output end, the coupling area is arranged between the waveguide and the resonator, and a corresponding relation is established between the area information of the coupling area and the smoothing rate T (lambda) of the LED.

Description

technical field [0001] The invention relates to the field of optoelectronic technology, in particular to a filtering structure applied to LEDs and an LED display screen. Background technique [0002] Traditional LED (Light Emitting Diode, light-emitting diode), including ELC (Embedded LED Chip), SMDL (Surface Mounted Device LED), FCL (Flip-Chip LED), etc., but no matter what kind of LED, it shows that the light source is outputting The blue light component of the spectrum has a damaging effect on the retina, because too strong short-wave blue light can easily cause photochemical damage to the photoreceptor cells on the retina and degeneration of the pigment epithelial function, and too strong radiation can also cause thermal damage to the retina. [0003] The spectrum of LED is discontinuous, the wavelength is single, and the spectral energy of short wavelength is very high.

Problems solved by technology

[0002] Traditional LED (Light Emitting Diode, light-emitting diode), including ELC (Embedded LED Chip), SMDL (Surface Mounted Device LED), FCL (Flip-Chip LED), etc., but no matter what kind of LED, it shows that the light source is outputting The blue light component of the spectrum has a damaging effect on the retina, because too strong short-wave blue light can easily cause photochemical damage to the photoreceptor cells on the retina and degeneration of the pigment epithelium function, and too strong radiation can also cause thermal damage to the retina

[0003] The spectrum of LED is discontinuous, the wavelength is single, and the spectral energy of short wavelength is very high. Long-term exposure to strong light in one band will inevitably reduce the ability to distinguish other colors, resulting in a high possibility of color weakness. At the same time, Prolonged use can easily cause visual fatigue

[0004] Therefore, in order to solve the technical problem of visual damage caused by the single wavelength of LED mentioned above and the high spectral energy of its short wavelength, it has become another important topic for current technicians in the field of LED research.
