Embodiment Construction

[0041] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0042] For a display panel used as a transparent display, the display panel generally includes periodically arranged light-transmitting regions. Generally, the width of the light-transmitting regions ranges from several microns to tens of microns, so that when external light passes through the light-transmitting regions When , objects or images on the non-light-emitting side of the display panel are visible. However, the periodically arranged light-transmitting regions are equivalent to gratings with fixed grating...

Abstract

The invention discloses a display panel, a display device and a preparation method. The display panel includes: a display area, the display area includes a transparent display area, the transparent display area includes a light-transmitting area distributed in an array, and the transparent display area also includes a plurality of light-emitting areas , the light-emitting area is located between adjacent light-transmitting areas; the base substrate; a plurality of first light-emitting elements are located on one side of the base substrate, and the light-emitting elements are located in the light-emitting area; in the transparent display area, at least two adjacent light-transmitting The thickness of the film layer in the regions is different, and / or the material of the film layer in at least two adjacent light-transmitting regions is different. The invention provides a display panel, a display device and a preparation method to solve the problem that the light in the transparent area of ​​the display panel is easy to diffract and affect the display effect of the display panel.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel, a display device and a manufacturing method. Background technique [0002] Organic Light Emission Diode (OLED) display is a self-emissive display that uses organic light emitting diodes for light to display images. Features, at the same time has the advantages of high definition, wide viewing angle, and fast response speed. [0003] Organic light emitting diode displays use emitted light to display images and can also be fabricated as transparent display devices that allow users to view objects or images on the opposite side of the organic light emitting diode display. In general, a transparent display device includes a plurality of uniformly arranged transparent regions, so that the light on the opposite side of the transparent display device passes through the above-mentioned transparent regions, but the light rays will be diffracted when passing thro...
