Title:
FINGERPRINT CHIP DETECTION METHOD, DEVICE AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/227475
Kind Code:
A1
Abstract:
A fingerprint chip detection method and device, a touchscreen development board, and an electronic terminal. The fingerprint chip detection method comprises: controlling a fingerprint chip to repeatedly execute a test instruction for testing a service life of the fingerprint chip until a test result reaches a set abnormal condition and/or the test time reaches a set test time (S102); and determining the detection result of the fingerprint chip according to an operating parameter when the test result reaches the set abnormal condition or the test time reaches the set test time (S104). The detection efficiency is effectively improved, and the detection result is determined by means of the corresponding operating parameter, so that the detection result is accurate, and the detection error is reduced.
