Abstract

The embodiment of the invention provides a display panel and a mobile terminal. The display panel comprises a substrate and a light-emitting device, the light-emitting side, close to the light-emitting device, of the substrate is provided with a visual angle adjusting structure, the visual angle adjusting structure comprises a first refractive index layer with a plurality of grooves and a second refractive index layer with a plurality of protrusions, and each protrusion corresponds to the corresponding groove. The refractive index of the second refractive index layer is smaller than that of the first refractive index layer; according to the display panel, the viewing angle adjusting structure is arranged on the light-emitting side of the light-emitting device, the viewing angle adjusting structure comprises the first refractive index layer with the multiple grooves and the second refractive index layer with the multiple protrusions, and the refractive index of the second refractive index layer is smaller than that of the first refractive index layer. The light emitted by the light-emitting device generates a diffuse refraction phenomenon on the interface between the first refractive index layer and the second refractive index layer, so that the display visual angle of the display panel is increased, and the display effect 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 mobile terminal. Background technique [0002] Active Matrix Organic Light Emitting Diode (AMOLED) display panels are driven by thin-film transistors, which can light up each pixel individually, with high brightness, high resolution, low power consumption, and easy color realization. It has advantages such as optimization and large-area display, and it is a method commonly used now. [0003] At present, OLED display devices are limited to the development of light-emitting materials, and the light extraction efficiency is low, so it is difficult to reach the mass production level for practical use. In response to this, engineers prepared OLED display devices in the cavity length between cathode and anode, and greatly improved the luminous efficiency of OLED display devices through the principle of laser resonant cavity. However, with the introduc...
