Embodiment Construction
[0045] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0046] The outer side of the currently used display device is generally equipped with a protective cover for protecting the light-emitting device. Usually, glass material is used. Taking the OLED display as an example, the brightness-viewing angle characteristic curve of the OLED device at 9V is as follows: figure 1 As shown, wherein, the curve surrounded by white squares represents the standard Lambertian distribution (Lambertian distri...

Abstract
The invention discloses a display panel, a manufacturing method thereof and a display device, comprising: a plurality of light-emitting units, a transparent substrate located on the light-emitting side of the light-emitting units, and at least one transparent film layer located on the surface of the transparent substrate on a side away from each light-emitting unit The refractive index of each transparent film layer is lower than the refractive index of the transparent substrate; the refractive index of each transparent film layer decreases sequentially along the light emitting direction of the light emitting unit. On the transparent substrate on the light emitting side of the light-emitting unit, at least one transparent film layer whose refractive index decreases successively is arranged, so as to reduce the difference in the medium refractive index when the light is emitted from the transparent substrate to the outside, and then the light is at the interface of each medium layer The critical angle is increased, which can make the light emitted at a large angle emerge, thereby improving the problem of low light intensity at a large viewing angle.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a display panel, a manufacturing method and a display device. Background technique [0002] With the rapid development of display technology, displays have entered all aspects of people's lives, and with the popularization and use of smart terminals, users have also put forward higher requirements for the viewing effect of displays. [0003] Existing displays generally use Liquid Crystal Display (LCD for short) or Organic Light-Emitting Diode (OLED for short), and no matter what kind of display the outside will include a transparent protective cover, this protection The difference between the refractive index of the cover plate and the refractive index of the environment (such as: air) makes the large-angle light emitted by the display completely reflected when it enters the interface between the protective cover plate and the environmental medium and cannot be emitted outward. ...
