Problems solved by technology

[0004] However, while the polarizer blocks ambient light, it also blocks the light emitted by the light-emitting device, resulting in less light emitted from the OLED display panel among the light emitted by the light-emitting device, which affects the light output efficiency of the OLED display panel.

Embodiment Construction

[0064] In order to make the purpose, technical solutions and advantages of the application clearer, the application 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 application, not all of them. . Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0065] In the display industry, a polarizer is usually attached to the light-emitting surface of the OLED display panel to reduce the interference of ambient light on the light emitted by the OLED display panel. However, the thickness of the polarizer is relatively large, resulting in a greater impact of the polarizer on the light extraction efficiency of the OLED display panel. In addition, the thickness of the display panel is relatively large, making it difficult ...

Abstract

The application discloses a display panel and a manufacturing method thereof and a display apparatus, which belong to the technical field of display. The display panel includes an underlayment substrate, and a light emitting device and a packaging structure arranged on the underlayment substrate in turn. The packaging structure includes at least one first packaging film layer, the first packagingfilm layer includes at least two stacked inorganic layers, and the refractive index of the at least two inorganic layers increases in turn along the direction towards the light emitting device. The first packaging film layer is configured to adjust the angle of ambient light shot into the light emitting device to reduce ambient light reflected from the display panel. The interference of ambient light to the light emitted by the display panel can be reduced without setting a polarizer, and the light output efficiency of the display panel is ensured. The technical scheme of the application is used to reduce the interference of ambient light to the light emitted by the display panel.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] With the development of display technology, organic light-emitting diode (English: Organic Light Emitting Diode; abbreviation: OLED) display panels are becoming more and more popular due to their high brightness, wide color gamut, high resolution and low power consumption. It is widely used in high-performance display products. [0003] The OLED display panel has a light-emitting device, the light-emitting device includes a light-emitting layer and electrodes (such as an anode and a cathode) for driving the light-emitting layer to emit light, and the OLED display panel realizes display by emitting light through the light-emitting layer. In the environment where the OLED display panel is located, the ambient light irradiated to the light-emitting device at a certain ang...
