“…Once it was proposed, it attracted lots of attention and research [3][4][5]. However, there are also two distinct challenges that lead to the imaging quality of UDC being severely degraded and prevent it from being widely accepted and used because the camera is placing beneath the display.…”

A novel under‐display camera structure with high transmittance up to 40.8% was proposed to increace transmittance, in which all pixel circuits and metal traces were moved to the transition zone which is right next to the UDC zone, and the circular polarizer was replaced with COE, and then the metal cathode is patterned by self‐assembly method, and the disconnected cathodes are connected together by transparent auxiliary cathode.

“…In order to predict and evaluate the diffraction performance of a specific CUP backplane design, we proposed a diffraction simulation system based on VirtualLab Fusion and Matlab, which can utilize CUP backplane layouts to visualize the diffraction properties [4]. The simulation diffraction patterns of TFT-Inside CUP design and TFT-Outside CUP design is shown in Figure 2a and Figure 2b, respectively.…”

In this paper, we report the novel design and fabrication of OLED (organic light‐emitting diode) Camera‐under panels (CUP) with improved transmittance and imaging quality. We utilized TFT (thin film transistor)‐outside structure and patterned cathode in the CUP region. The diffraction simulation, transmittance test, Point spreading function (PSF) test, and scene photos proved the efficiency of our solution. Remarkable enhancement of imaging performance, which was identical to that of a normal AA‐hole OLED panel, was achieved. The results confirm the effectiveness of our CUP design strategy and also the potential of our design to be commercially used in the industry.
