Abstract
Under Screen Face Authentication (USFA) has become the future development trend. By optimizing the Pixel Shape in the sub-display area and separating the Pixel circuit from the physical position of OLED devices, we still maintain the independent pixel driving mode to realize OLED luminescence with the main display area. In this way, we can maximize the screen transmittance and improve diffraction to better match the response of photosensitive components to light and the difficulty of algorithm compensation. Through further optimization with trinamiX BPA Face authentication hardware & diffraction algorithm, the USFA technology is realized.
