Description:

With the advancement of technology, integrating the display screen and front-facing lens into an under-display camera (UDC) device has become a breakthrough innovative technology for borderless and immersive visual experience. This article discusses the image quality improvement of micron light-emitting diode (Micro-LED) UDC technology and explains the relevant research results. Through time-sharing driver and pixel layout design optimization, the light spot problem is effectively solved, ensuring that the front screen can still display content normally when the UDC camera is shooting. In addition, through optical diffraction simulation and image quality analysis of different pixel designs, we successfully developed a low-diffraction pixel design suitable for Micro-LED UDC applications. Based on the above experimental results, we have successfully implemented Micro-LED UDC technology. This technology will be prioritized in the field of automotive display in the future, and we will continue to work on improving the quality of UDC images.
