Abstract

The embodiment of the invention discloses a display panel. The display panel comprises a light-emitting material layer and a first electrode layer. The light-emitting material layer comprises: a plurality of first-type light-emitting devices, wherein the ratio of the first distance between the light-emitting center of each first-type light-emitting device and the first electrode layer to the wavelength of the light-emitting color of the corresponding first-type light-emitting device is a first ratio; and a plurality of second-type light-emitting devices, wherein the ratio of a second distance between the light-emitting center of each second-type light-emitting device and the first electrode layer to the wavelength of the light-emitting color of the corresponding second type of light-emitting device is a second ratio, and the first ratio is different from the second ratio. According to the embodiment of the invention, the at least two types of light-emitting devices are arranged, the ratios of the distances between the light-emitting centers and the first electrode layers to the wavelengths of the corresponding light-emitting colors of the light-emitting devices are not equal, and micro-cavity structures of different ratio types are formed, so that the light-emitting efficiency of the light-emitting devices of different colors can be further improved, the color saturation of emergent light is improved, and the light-emitting service life of the devices is prolonged.

Description

technical field [0001] The invention relates to the display field, in particular to a display panel. Background technique [0002] In the current OLED (Organic Light-Emitting Diode, Organic Light-Emitting Semiconductor) display panel, the color saturation of outgoing light and the luminous efficiency of the device can be enhanced by utilizing the resonant cavity effect. For example, for light-emitting devices of different colors, the luminous efficiency of the corresponding light-emitting device can be improved by adjusting the distance between the center of the light-emitting device and the microcavity of the anode layer, and making the distance between the microcavity and the wavelength of the corresponding color a certain value. However, due to the different luminous efficiencies of light-emitting devices of different colors, the current setting of the microcavity spacing cannot make the luminous efficiency of each light-emitting device reach an optimal value.
