LIGHT SPOT DISPLAY METHOD AND APPARATUS
Abstract:
A light spot display method and an apparatus are disclosed. After a fingerprint event in a fingerprint detection area is detected, a light spot drawing instruction is generated, and a light spot is drawn in response to the light spot drawing instruction to obtain light spot display data, and fingerprint scenario marking information and the light spot display data are simultaneously sent, so as to ensure that a display driver synchronously receives the fingerprint scenario marking information and the light spot display data. This solution reduces the time consumed in the light spot display process, that is, increases the light spot display speed. The fingerprint image can be obtained and the fingerprint can be recognized only after the light spot is normally displayed. Therefore, this solution increases the speed of responding to a fingerprint event, and then reduces the time consumed in the entire fingerprint recognition process.
