Problems solved by technology

[0005] Although the above-mentioned technologies can absorb or convert the harmful bands of blue light, they will lead to problems such as color impurity and high cost
For example, when the above-mentioned spectacle lenses are used to filter blue and violet light bands, the filtering function of the lenses will significantly affect the color of the image, resulting in color shift, thus destroying the viewing quality of the image
Although the above-mentioned yellow light absorption structure embedded in the backlight module can absorb the harmful blue light band, it will make the display screen appear yellowish, thus affecting the color quality

[0025] figure 1 is a schematic structural view of the display device according to the first embodiment of the present invention. Such as figure 1 As shown, the display device 100 a includes a backlight module 20 and a display panel 10 a disposed on the backlight module 20 . The light emitted by the backlight module 20 passes through the display panel 10a to enable the display panel 10a to display images. The display device 100a is provided with a blue light-absorbing zinc selenide film 142 (ZnSe) to filter low-band blue light, for example, filter blue light less than 460nm, and reduce the damage of blue light to human eyes. In this embodiment, the display device 100a includes a plurality of pixels, and each pixel includes a red sub-pixel, a green sub-pixel and a blue sub-pixel.

[0026] Such as figure 1 As shown, the display panel 10a includes a color filter substrate 12 , an array substrate 14 disposed opposite to the color filter substrate 12 , and a liquid crystal layer...

[0036] figure 2 is a schematic structural diagram of a display device according to a second embodiment of the present invention. Such as figure 2 As shown, the structure of the display device 100 b of this embodiment is substantially the same as that of the display device 100 a of the first embodiment, except that the shape of the zinc selenide film 142 is different.

[0037]Specifically, the array substrate 14 includes a bottom plate 141 , a zinc selenide film 142 , a protective film 143 and a circuit layer 144 . The zinc selenide film 142 is disposed on the base plate 141, the protective film 143 is disposed on the base plate 141 and the zinc selenide film 142, and the circuit layer 144 is disposed on the protective film 143. The zinc selenide film 142 is disposed on the surface of the bottom plate 141 facing the liquid crystal layer 16 or on the surface of the bottom plate 141 facing the backlight module 20. When the zinc selenide film 142 is disposed on the surface of ...

Abstract

The invention provides a display device. A zinc selenide membrane absorbing blue light is arranged on the display device. The display device can filter the low band blue light and reduce injuries of the blue light to human eyes.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device. Background technique [0002] Some scientists have pointed out that the high-energy short-wave blue light with a wavelength between 400nm and 500nm will be absorbed by the lens of the human eye and the macula of the retina, thereby causing irreversible damage to the glasses, especially the blue light with a wavelength of less than 450nm. The human eye hurts the most. Studies have proved that if 50% of the energy in the 430±30nm band is blocked, the death rate of retinal pigment epithelial (RPE) layer cells caused by blue light will be reduced to 20%. [0003] In recent years, due to people's desire for information, manufacturers have continuously developed and launched various novel display devices to visually convey various information and satisfy people's desire. However, with the popularization and extensive use of display devices, the number of pa...
