Problems solved by technology

[0002]In recent years, OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) display panels are popular all over the world due to their high contrast, wide color gamut, and fast response time. Use, the latitude and longitude of different regions in the world are different, resulting in different energy of ultraviolet radiation in different regions. In order to study the limit of the solar illumination experiment conditions of OLED display panels, artificial sunlight or ultraviolet mask experiments are usually used to simulate the solar illumination of OLED display panels. However, after the OLED display panel is irradiated by sunlight or ultraviolet light, the color temperature of the display will decrease, which will affect the display effect

Abstract

The embodiment of the invention discloses a display panel and a mobile terminal. The display panel comprises a light-emitting functional layer and a thin film packaging layer, the light-emitting functional layer comprises a plurality of first light-emitting units and a plurality of first light extraction units located between the first light-emitting units and the thin film packaging layer, and the extinction coefficient of the first light extraction units to ultraviolet light is larger than that of the thin film packaging layer to ultraviolet light. According to the embodiment of the invention, the first light extraction unit comprising the ultraviolet light absorption material is arranged between the first light emitting unit and the thin film packaging layer, so that when sunlight or ultraviolet light irradiates the display panel, the first light extraction unit plays a role in absorbing or extinction the ultraviolet light. The problem that the color temperature of the display panel is reduced due to the fact that the light-emitting materials in the first light-emitting units are damaged by ultraviolet light is relieved, and the display effect of the display panel is improved.

Description

technical field [0001] The present invention relates to the display field, in particular to a display panel and a mobile terminal. Background technique [0002] In recent years, OLED (Organic Light-Emitting Diode, organic light-emitting semiconductor) display panels have been used all over the world due to their advantages such as high contrast, wide color gamut, and fast response time. The energy is different. In order to study the limit of the solar illumination experiment conditions of the OLED display panel, artificial sunlight or ultraviolet light mask experiments are usually used to simulate the solar illumination service life of the OLED display panel. , will cause the display color temperature to decrease and affect the display effect. [0003] Therefore, there is an urgent need for a display panel and a mobile terminal to solve the above technical problems. Contents of the invention [0004] Embodiments of the present invention provide a display panel and a mobi...
