Under screen fingerprint sensor timing control

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, are disclosed for off-screen fingerprint sensor timing control. In one embodiment, a method includes receiving, by a fingerprint sensor control circuit, an indication to activate a fingerprint sensor located beneath a display panel of a computing device, the fingerprint sensor attached relative to the display panel, exposing the fingerprint sensor to light generated by the display panel and reflected from a finger placed above the display panel at the location of the fingerprint sensor; outputting a start sensing trigger signal for reception by the fingerprint sensor at a start time synchronized with a display panel timing signal provided to the display panel to control emission of the display panel; and outputting a stop sensing trigger signal for the fingerprint sensor to receive at a stop time synchronized with the display panel timing signal. 公开了用于屏下指纹传感器定时控制的方法、系统和装置，包括编码在计算机存储介质上的计算机程序。一种方法包括：由指纹传感器控制电路接收激
