Description:

Sensor integration in pixel circuits is emerging as an important development for transparent displays and automotive applications. This paper highlights the dual role of micro-LEDs as both light-emitting and ambient light-sensing elements. We propose a pixel driving method that enables micro-LEDs to both emit light and serve as ambient light sensors. Additionally, we demonstrate a 12.4-inch transparent display integrated with sensor-in-pixel functionality, with the aim of enhancing the adaptability of displays in diverse environmental conditions. This work paves the way for innovative developments in transparent display technology.
