From: Transparent OLED displays for selective bidirectional viewing using ZnO/Yb:Ag cathode with highly smooth and low-barrier surface

Fig. 6

a, b Comparison of conventional TrOLED display with one-side viewing and novel TrOLED display with bidirectional viewing. c, d Pixel structure and photographs in the one-side-view mode, e, f identical dual-view mode, and g, h identical or augmented dual-view mode, respectively. A mirror was placed behind the device to observe the rearview. i Equivalent circuit for a pixel of novel TrOLED. j–m Scan signals to correspond to four types of display modes. Here, k and l are identical dual view modes but have different brighter side
