Abstract:
Embodiments of the present disclosure provide a display panel, a method of manufacturing the display panel, a fingerprint identification device, and a method of identifying a fingerprint. The display panel includes first and second substrates. The first substrate is formed with switch transistors arranged in an array, and photosensitive elements arranged in an array and connected with the switch transistors. The second substrate is formed with conductive contact members, the contact members each have an end adjacent to the first substrate, and the end of each of the contact members is spaced from the first substrate so that when the second substrate is deformed by a force, the end of at least one of the contact members electrically contacts the first substrate so that at least one of the switch transistors in a position corresponding to the at least one of the contact members is turned on.
