Double-sided display substrate and preparation method and display device thereof

Abstract

The invention provides a double-sided display substrate and a preparation method and a display device thereof. The double-sided display substrate comprises a plurality of sub-pixel units, wherein each sub-pixel unit comprises a front luminescent layer, a reverse luminescent layer, a pixel electrode layer, a common electrode layer and a drive transistor; each front luminescent layer is used for carrying out front displaying; each reverse luminescent layer is used for carrying out reverse displaying; each front luminescent layer and each reverse luminescent layer are respectively clamped between the corresponding pixel electrode layer and common electrode layer; each drive transistor is used for controlling the corresponding front luminescent layer and reverse luminescent layer to shine; and the common electrode layers corresponding to the front luminescent layers and / or the reverse luminescent layers, and gate electrode layers of the drive transistors are arranged on the same layer. According to the double-sided display substrate, the thickness and the volumeof the double-sided display substrate can be effectively reduced; the preparation cost and the energy consumption cost of the double-sided display substrate are reduced; the design difficulty is lowered; the production cycle of the display substrate is shortened; and the yield and the display quality of the display substrate are improved, so that rapid preparation and popularization of the double-sided display substrate are achieved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a double-sided display substrate, a preparation method thereof, and a display device. Background technique [0002] More and more attention has been paid to display products that use thin-film transistors as control elements and organic electroluminescent devices (OLEDs) as light-emitting media because of their advantages such as high definition, wide viewing angles, and easy realization of flexible and flexible displays. [0003] With the application of OLED display products, OLED display screens with double-sided display effects are required in more and more occasions. At present, the double-sided display OLED display mainly adopts the method of laminating two single-sided OLED screens 10 to realize the double-sided display effect, such as figure 1 shown. The preparation process of this method is complicated, and each film layer structure in the OLED screen and the t...

AI Technical Summary

Problems solved by technology

The preparation process of this method is complicated, and each layer structure in the OLED screen and the thin-film transistor driving circuit need to be prepared in duplicate, which is not only not conducive to reducing the preparation cost and energy consumption cost of the double-sided OLED display screen, but also has excessive thickness and volume. Large, heavy and other shortcomings; at the same time, it will also affect the yield and display quality of OLED double-sided displays

The above defects not only prolong the production cycle of OLED double-sided display, but also are not conducive to the rapid promotion of OLED double-sided display in the market
