The display appears to have a sleep mode that highlights the correct area on the OLED panel where the sensor resides. That means that you've had to move your fingerprint sensor from the front, where many like it the best, to the back, or, as is the iPhone X's case, remove it completely.

The market research firm says in addition to Korean brands Samsung and LG, which make their own AMOLED panels, Chinese smartphone brands such as OPPO, Vivo, Meizu, Gionee, Xiaomi and Huawei will have a chance to embed an in-display fingerprint sensor for AMOLED panels in their new models to release in 2018.
