Display device

Abstract

The invention provides a display device which can reduce blue light output. The technical proposal is as follows: the display interface of the display device is coated by a photo-absorption material layer which has low transmissivity to the blue light within a specific wavelength section; as for the luminescent display device with a backlight lamp, the blue light output intensity of the backlight lamp on the specific wavelength section is reduced; as for the display device which illuminates by fluorescent powder, the content or composition of the fluorescent powder which generates the blue light is reduced or adjusted, thus realizing reducing the blue light intensity or adjusting the spectral curve and leading the wave crest of the blue light to deviate by a range of 420-455nm. Compared with the prior art, by reducing the blue light output of the display device or changing the spectral curve of the blue light in the display device, the wave crest of the blue light is deviated by the range of 420-455nm where the damage factor to human eyes is largest, thus reducing the damage of the blue light to the human eyes and achieving the purpose of protecting the eyesight.

Description

【Technical field】 [0001] The invention relates to a display device, in particular to a display device that reduces visual damage caused by blue light. 【Background technique】 [0002] Research by the International Commission on Illumination (CIE) has shown that compared with other colors (wavelengths), blue light with a wavelength between 400nm and 500nm causes more obvious discomfort and disability than other long-wavelength green and red lights glare. The human eye lens system cannot sharply focus on blue light. Unlike red and green light, which can accurately focus on the retina, the focus position of blue light will be slightly ahead of the retina, which leads to the uniqueness of blue light. halo. Also, blue travels through the eye more widely than other colors. Intense blue electric light sources are particularly prone to this, spreading across the retina and interfering with other parts of the scene. [0003] Visible light acts on the human eye as both light radiat...

Problems solved by technology

In addition, human beings are quite sensitive to blue light in a dark environment, so blue is not suitable for home appliances in the bedroom, because their light intensity is too irritating to human eyes.

[0006] Blue light will have a significant impact on the body's biological clock, but if you watch TV or use a computer for a long time at night, too strong blue light will stimulate the formation of melatonin and cause symptoms such as insomnia
