Abstract

The invention provides a display substrate and a display device. The display substrate comprises a light-emitting area and a light-emitting area. The display substrate comprises a back plate; the light-emitting unit is arranged on one side of the back plate and located in the light-emitting area; the reflecting layer is arranged on the side, away from the back plate, of the light-emitting unit and comprises a first sub-reflecting layer and a second sub-reflecting layer, at least part of the first sub-reflecting layer is arranged in the light-emitting area, and at least part of the second sub-reflecting layer is arranged in the light-emitting area; the first sub-reflection layer is used for reflecting emergent light of the light emitting unit to the second sub-reflection layer, and the second sub-reflection layer is used for reflecting the emergent light to the part, located in the light emitting area, of the back plate to be emitted out. According to the display substrate and the display device provided by the invention, the quantity of high-energy blue light in the light emitted out of the light emitting area can be reduced, the damage of the high-energy blue light to human eyes is greatly reduced, an eye protection function is realized, and a white picture cannot become yellow.

Description

technical field [0001] The present disclosure relates to the field of display technology, and in particular, to a display substrate and a display device. Background technique [0002] OLED (Organic Light Emitting Diode, Organic Light Emitting Diode) display device has a series of advantages such as self-luminescence, high contrast, high definition, wide viewing angle, low power consumption, fast response speed, and low manufacturing cost, and has become a new generation of display devices. One of the key development directions, so it has received more and more attention. [0003] The outgoing light of the OLED display device includes a large amount of low-wavelength blue light, and the low-wavelength blue light is more harmful to human eyes. At present, the eye protection function is mainly achieved by setting the night mode to reduce the proportion of blue light in the white balance. [0004] However, this method will make the white picture look seriously yellow, affectin...
