Abstract
A fingerprint-sensing array on a substrate includes the substrate, scan lines, data lines, readout lines, sub-pixels, and multiple fingerprint recognition units. Areas between adjacent scan lines and adjacent data lines define one sub-pixel with pixel electrode and a first transistor. Of the first transistor, drain electrode connects to the pixel electrode, source electrode connects to one data line and gate electrode connects to one scan line. Thus some of the sub-pixels contain fingerprint recognition units, these being a photodiode electrically connected to one readout line. The readout line passes signals generated by the photodiode to achieve fingerprint recognition function. A display panel using the array on the substrate and a display device using the display panel are also provided.
