Abstract
The invention discloses a display panel, which comprises a substrate, a first refraction layer, a transparent electrode layer, a light-emitting layer, a reflecting electrode layer and a second refraction layer, wherein the first refraction layer is arranged on the substrate; the transparent electrode layer is arranged on the first refraction layer; the light-emitting layer is arranged on the transparent electrode layer; the reflecting electrode layer is arranged on the light-emitting layer; the second refraction layer is arranged on the other side, which is away from the first refraction layer, of the substrate; a refractive index of the second refraction layer is greater than a refractive index of the substrate, a refractive index of the substrate is greater than a refractive index of thefirst refraction layer, a refractive index of the first refraction layer is greater than a refractive index of the transparent electrode layer, and a refractive index of the transparent electrode layer is greater than a refractive index of the light-emitting layer, so that emergent light can be vertically emitted out of the display panel, the visual angle of the display device is reduced, and theprivacy in use is improved. The invention further provides a display device comprising the display panel.
Description
technical field [0001] The disclosure relates to the field of display technology, and in particular, to a display panel and a display device with a switchable narrow viewing angle. Background technique [0002] OLED display technology has been applied in smart phones, tablet computers and other fields. At present, the wide viewing angle display technology belongs to the mainstream development direction of existing display panels (such as OLED display panels). For example, laptops, tablet computers, mobile phones and other portable electronic devices with wide viewing angles all adopt wide viewing angle display technology, so that people can see a complete and undistorted picture when viewing the display panel in a wide viewing angle mode from different directions. . However, when it comes to personal privacy and important information, for example, in public places, many people do not want their mobile phones or computers to be seen by others, and hope that their privacy ca...
