Abstract

The embodiment of the invention discloses a display substrate, a preparation method thereof and a display device. The display substrate comprises: a substrate body, a driving structure layer arrangedon the substrate, and a light-emitting structure layer arranged on the driving structure layer; and the light-emitting structure layer comprises a first light-emitting structure and a second light-emitting structure. The first light-emitting structure comprises a first transparent anode, a first light-emitting layer and a first cathode which are stacked in the direction from the position close tothe driving structure layer to the position away from the driving structure layer, and the second light-emitting structure comprises a second reflection anode, a second light-emitting layer and a second cathode which are stacked. According to the display substrate provided by the embodiment of the invention, the light-emitting structures with different light-emitting directions are arranged on thesame side of the substrate, so that double-sided display is realized, and the difference between the thickness of the display substrate and the thickness of single-sided display is not large and is smaller than that of a double-sided display panel obtained by laminating two single-sided display panels.

Description

technical field [0001] The embodiments of the present application relate to display technology, in particular to a display substrate, a manufacturing method thereof, and a display device. Background technique [0002] Organic Light-Emitting Diode (OLED) has the advantages of self-luminescence, low driving voltage, and high luminous efficiency. It is a display lighting technology that has developed rapidly in recent years, and because of its high response, high contrast, and flexibility. , is considered to have broad application prospects. In addition to the various characteristics of ordinary OLED displays, the double-sided OLED display can also extend the screen space, quickly switch and process multiple display screens, which not only saves the production cost of the display, but also saves the space of the device. [0003] Currently, a display panel with double-sided display is made by laminating two display panels with single-sided display. The thickness of the display...
