Embodiment Construction

[0043] In order to facilitate the understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Preferred embodiments of the application are shown in the accompanying drawings. However, the present application can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the application more thorough and comprehensive.

[0044] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of ill...

Abstract

The invention relates to a display panel and a display device. The display panel comprises a driving substrate, a reflection cup structure, a light emitting unit, a first packaging layer and a second packaging layer. The reflection cup structure comprises a plurality of comprising cavities arranged at intervals. The light-emitting unit is arranged in the comprising cavity. The first packaging layer and the second packaging layer are used for packaging the light-emitting unit. The reflection cup structure can form an important barrier for spacing the light-emitting units with different colors, and optical crosstalk and color crosstalk of the light-emitting units are inhibited. The refractive index of the first packaging layer is smaller than that of the second packaging layer, so that the emergent angle of light entering the second packaging layer from the first packaging layer through the contact interface of the first packaging layer and the second packaging layer is smaller than a critical angle, and the propart that the light is transversely transmitted to other structures to be absorbed is reduced; therefore, the light extraction efficiency 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] In the current light-emitting devices, there is a common phenomenon that the light emitted by the light source cannot be fully utilized. Due to the design defect of the light emitting device, there is a large amount of loss in the transmission process of the light. For example, more light is emitted from the sidewall of the light emitting device, which leads to the occurrence of optical crosstalk and affects the overall light extraction efficiency of the light emitting device. Contents of the invention [0003] Based on this, it is necessary to provide a display panel and a display device for the traditional light-emitting device, which has a large loss of light during transmission, which leads to the occurrence of optical crosstalk and affects the overall light extraction efficiency of the light-em...
