摘要： This disclosure relates to an optical fingerprint identification display screen and a display device. In this disclosure, a plurality of photosensitive elements for fingerprint identification is arranged on an array substrate, such that mesh regions of a mesh-like black matrix layer corresponds to the photosensitive elements. A plurality of light guide members at least covering each of the photosensitive elements is arranged between each photosensitive element and the counter substrate. Since the light guide members and the counter substrate are in contact with each other, light reflected from ridges and valleys of a fingerprint will enter the light guide members maximally after passing through the mesh regions of the black matrix layer, and then directly impinge on the photosensitive elements after refraction within the light guide members.

摘要： The present disclosure relates to a fingerprint identification module, including: a plurality of sensing units, wherein each sensing unit receives modulation signal when turned on, the modulation signal covers at least one first time interval and at least one second time interval, and the voltages during the first and second time intervals are respectively first and second voltages; a collecting unit for collecting output signals of the sensing units in the same column in all the first time intervals as a first signal and those in all the second time intervals as a second signal; and a calculating unit for determining the difference between the first and second signals to obtain a third signal and obtaining the fingerprint information sensed on the basis of the third signal. Through the above solution, it is possible to eliminate the influence of the leakage current in the sensing unit, thereby accurately identifying fingerprints.
