摘要
目前的显示屏幕通常只用于信息显示，但可以集成一系列不同的传感器，以实现触摸控制、环境光感应和指纹感应等功能。光响应发光二极管（LED）可以显示信息并对光激励做出响应，可用于开发未来的超薄和大屏幕与机身比例屏幕。然而，传统的显示技术很难实现光响应。在此，我们报告了一种使用光响应金属卤化物包晶 LED 作为像素的多功能显示屏。这种过氧化物 LED 显示屏可同时用作触摸屏、环境光传感器和图像传感器（包括指纹绘制），而无需集成任何其他传感器。像素的光电转换效率还可使显示屏充当光伏设备，为设备充电。
A multifunctional display based on photo-responsive perovskite light-emitting diodes
Current display screens are typically only used for information display, but can have a range of different sensors integrated into them for functions such as touch control, ambient light sensing and fingerprint sensing. Photo-responsive light-emitting diodes (LEDs), which can display information and respond to light excitation, could be used to develop future ultra-thin and large screen-to-body ratio screens. However, photo-response is difficult to achieve with conventional display technologies. Here, we report a multifunctional display that uses photo-responsive metal halide perovskite LEDs as pixels. The perovskite LED display can be simultaneously used as a touch screen, ambient light sensor and image sensor (including for fingerprint drawing) without integrating any additional sensors. The light-to-electricity conversion efficiency of the pixels also allow the display to act as a photovoltaic device that can charge the equipment. Photo-responsive metal halide perovskite light-emitting diodes can be used to create a multifunctional display that can function as a touch screen, ambient light sensor and image sensor.
