Problems solved by technology

At the same time, in the double-sided display formed by bonding two display panels, there are control switches such as TFTs and related circuits on each display surface. The TFT structure is complex and the manufacturing process is complicated, especially in the LTPS process. Therefore, the panel utilization rate is very low

Embodiment Construction

[0031] see Figure 1a and Figure 1b and Figure 2a and Figure 2b , is a schematic structural view of the first embodiment of the double-sided display device of the present invention. The double-sided display device includes a substrate 10, a TFT layer 20, a first light-emitting layer 30, and a first encapsulation layer 40 stacked in sequence above the substrate 10, and a second light-emitting layer stacked in sequence below the substrate 10. 50 and the second encapsulation layer 60 , wherein a plurality of via holes 70 penetrate through the substrate 10 and electrically connect the TFT layer 20 with the first light emitting layer 30 and the second light emitting layer 50 . Wherein, the first and second luminescent layers both include an anode, a luminescent material layer and a cathode. Although the present invention simplifies the double-sided display device into four structures of substrate, TFT layer, light-emitting layer, and encapsulation layer, these four structures...

Abstract

The invention discloses a double-surface display device. The double-surface display device comprises a substrate, a TFT layer, a first light emitting layer, a first packaging layer, a second light emitting layer and a second packaging layer, wherein the TFT layer, the first light emitting layer and the first packaging layer are successively laminated above the substrate; the second light emitting layer and the second packaging layer are successively laminated below the substrate. A plurality of vias penetrate through the substrate and electrically connect the first light emitting layer with the second light emitting layer.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a double-sided display device. Background technique [0002] The forms of electronic products are becoming more and more diversified, and the double-sided display function has become a feature of the new generation of electronic products. For example, the double-sided display inside the mobile phone can display the main function window of the mobile phone on one side, and the time on the other side; another example is the use of double-sided displays in public places so that people on both sides of the display can see various content displayed. The current double-sided display is usually made of two single-sided display panels facing each other, such as a liquid crystal display panel and an organic electroluminescent panel set back to back, or two organic electroluminescent panels set back to back, or two liquid crystal displays back to back set up. Such back-to-back display p...
