Problems solved by technology

[0004] But there are at least the following problems in the prior art: the LED backlight applied to TFT-LCD display devices brings great convenience to people's daily work and life, but also aggravates the problems caused by the human eyes facing various LEDs for a long time. Eye damage caused by light source (or display screen)
Among them, because the short-wave blue light has a smaller wavelength, it has a stronger excitation ability and is more harmful to the human eye.

Embodiment 1

[0041] Please refer to Figure 1 to Figure 8 , This embodiment provides a display device, including a display panel and an optical device 1. The optical device includes a first material layer 11 and a second material layer 12 alternately arranged, the refractive index of the first material layer 11 is greater than that of the second material The refractive index of layer 12; the optical device 1 is used to reduce the transmittance of short-wave blue light in the light incident on the display panel.

[0042] It should be noted that the light mentioned in this embodiment is white light, that is, mixed-color light. The optical device 1 of this embodiment only reduces the transmittance of short-wave blue light in the light without affecting other colors in the mixed-color light. The transmittance of light (such as red light, green light, etc.).

[0043] The reason for this setting is to make the refractive index difference between the first material layer 11 and the second material lay...

Embodiment 2

[0068] Please refer to Figure 9 to Figure 11 , This embodiment provides a display device, including a display panel and an optical device 1. The optical device includes a first material layer 11 and a second material layer 12 alternately arranged, the refractive index of the first material layer 11 is greater than that of the second material The refractive index of layer 12; the optical device 1 is used to reduce the transmittance of short-wave blue light in the light incident on the display panel. The difference from Embodiment 1 is that the display panel includes a first substrate 2 and a second substrate 3 that are arranged oppositely; the optical device 1 is located on the side of the first substrate 2 close to the second substrate 3; or, the optical device 1 is located on the first substrate 2 The side of the substrate 2 away from the second substrate 3.

[0069] Specifically, such as Picture 9 As shown, the optical device 1 is located on the side of the first substrate 2 ...

Embodiment 3

[0075] Please refer to Figure 12 to Figure 14 , This embodiment provides a display device, including a display panel and an optical device 1. The optical device includes a first material layer 11 and a second material layer 12 alternately arranged, the refractive index of the first material layer 11 is greater than that of the second material The refractive index of layer 12; the optical device 1 is used to reduce the transmittance of short-wave blue light in the light incident on the display panel. The difference from Embodiments 1 and 2 is that the display panel includes a first substrate 2 and a second substrate 3 disposed opposite to each other; the second substrate 3 includes a second substrate 32 and a second substrate 32 close to the first substrate 2 The blue sub-pixel 31 on one side; the first substrate 2 includes a first substrate 20, a thin film transistor 21 located on the first substrate 20, and a pixel electrode 22 connected to the thin film transistor 21. The op...

Abstract

The invention provides a display device and belongs to the technical field of display. The display device solves the problems that conventional display devices cause injury to the eyes of people because of short wave blue light existing in light emitted by LEDs. The display device comprises a display panel and an optical component. The optical component comprises first material layers and second material layers arranged alternately, wherein the refractive index of the first material layers is greater than that of the second material layers. The optical component is used for reducing the transmittance of short wave blue light in light emitted to the display panel.

Description

Technical field [0001] The invention belongs to the field of display technology, and specifically relates to a display device. Background technique [0002] With the light and thin development trend of liquid crystal displays (LCD), light emitting diodes (LEDs) have been widely used in backlight structures due to their light weight, small size, and low energy consumption. Moreover, its luminous power continues to increase and its optical performance continues to improve. Since the introduction of edge-type LED ultra-thin TVs in 2009, LCD display device products based on LED backlight design, such as LCD TVs, personal computers, smart phones, and tablet computers, have been popular in the market as soon as they came out. [0003] Among the light emitted by LEDs, in addition to invisible light including ultraviolet rays, which can cause damage to human eyes, studies have shown that blue light can also cause damage to human eyes. Blue light refers to the visible light with the highe...
