Abstract

The invention provides a transparent display panel, a preparation method thereof and a display device, and relates to the technical field of display. The high-reflectivity first electrode layer in the display substrate and the high-reflectivity second electrode layer in the touch substrate can be utilized to form a light guide structure, and small-angle light rays emitted by the light-emitting functional layer can pass through the first hollow area surrounded by the second electrode layer and are emitted from the pixel area close to one side of the touch substrate. The large-angle light rays emitted by the light-emitting functional layer enter the light guide structure, are reflected at least once through the light guide structure and then are guided to the transparent area close to one side of the display substrate to be emitted, and therefore double-face display is achieved. In the embodiment of the invention, the anode layer still has high reflectivity, so that the micro-cavity effect between the cathode and the anode can be ensured while double-sided display is realized, the narrowing effect of the emergent spectrum of the transparent display panel is further ensured, and the color purity during double-sided display is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a transparent display panel, a preparation method thereof, and a display device. Background technique [0002] The transparent display device has the effect of not blocking sunlight and seeing through, and is often used in glass curtain wall buildings, airports, hotels, stages, shop windows, etc., and has a great application prospect. [0003] At present, the way to realize double-sided display by using a transparent display device is mainly to change the anode in the transparent display panel from a highly reflective film layer to a semi-transparent or highly transparent film layer. refer to figure 1 , when the light emitted by the light-emitting functional layer a reaches the anode b, it is no longer completely reflected by the anode b, but part of it is reflected by the anode b and then emerges from one light-emitting surface, and the other part passes through the anode b to...
