Abstract

The invention relates to a display panel and a display device. The display panel comprises a substrate, a light-emitting layer, a packaging layer and a light filtering layer. According to the display panel, the light filter layer is arranged on the light emitting layer, and the light filter layer is used for filtering and adjusting the light emitted by the light emitting layer, so that the light emitting purity of the red light emitting unit and the green light emitting unit is improved, and the light emitted by the light emitting layer of the display panel is adjusted to R (0.708, 0.292), G (0.170, 0.797) and B (0.131, 0.046), so high BT2020 color gamut coverage is effectively realized; and finally, the color display capability of the display panel is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] With the development of display technologies, users' pursuit of display effects of display devices is also gradually increasing. In recent years, organic light-emitting display devices (English full name: Organic Light-Emitting Diode, referred to as OLED) have developed rapidly in the world. OLED has low voltage requirements, high power saving efficiency, fast response, light weight, thin thickness, simple structure, and low cost. , wide viewing angle, almost infinitely high contrast, low power consumption, high response speed and other advantages, has become one of the most important display technologies today. [0003] With the advent of ultra-high resolution displays such as 4K and 8K, users have further improved their color performance requirements. The standard definition of color gamut is the m...
