Abstract
A liquid crystal device with fingerprint identification function includes an array glass substrate, a colored light filtering glass substrate, an organic light-emitting layer, a pixel display layer and a detection wire and sensation electrode layer. The organic light-emitting layer, the pixel display layer and the detection wire and sensation electrode layer are disposed between the array glass substrate and the colored light filtering glass substrate. The pixel display layer cooperates with the internal wiring and electrode structures of the detection wire and sensation electrode layer to achieve complex functions of displaying, fingerprint detection/identification and touch control.
