Technical Field

The invention relates to the technical field of display, in particular to a transparent display panel.

Background

Compared with a conventional Liquid Crystal Display (LCD), an Organic Light-Emitting Diode (OLED) has the advantages of self-luminescence, fast response, wide viewing angle, high brightness, bright color, lightness, thinness, and the like, and is considered as a next generation Display technology.

In the transparent OLED display panel, a single pixel is divided into an opaque portion and a transparent portion, and in order to obtain a high transmittance, the area of the transparent region should be large, and the area of the opening of the sub-pixel should be small. If the transparent OLED display panel is manufactured by using an Ink Jet Printing (Ink Jet Printing) method, although the solution can be precisely sprayed into the pixel area to form the organic thin film, it is difficult to form the organic thin film with a uniform thickness in the pixel area because the opening area of the sub-pixel is small, and meanwhile, because the opening areas of the sub-pixels with three colors of red, green and blue are the same, the efficiency of the sub-pixel materials with three colors is different, and the service life of the sub-pixel is different, which results in a short service life of the transparent OLED display panel.

In summary, the problems of high difficulty of the ink-jet printing process and short service life of the display panel exist in the manufacturing process of the conventional transparent display panel. Therefore, it is necessary to provide a transparent display panel to improve this defect.
