DISPLAY ASSEMBLY, DISPLAY APPARATUS, AND FINGERPRINT RECOGNITION METHOD - A simplified explanation of the abstract
This abstract first appeared for US patent application 17915909 titled 'DISPLAY ASSEMBLY, DISPLAY APPARATUS, AND FINGERPRINT RECOGNITION METHOD
Simplified Explanation
The patent application is about display assemblies and fingerprint recognition methods. It describes a display assembly that includes a display panel and a fingerprint recognition module located on the surface of the display panel. The fingerprint recognition module consists of multiple fingerprint recognition units, each containing a phototransistor and a switch transistor. The phototransistor is made of an organic semiconductor material and has a first active layer, a first gate, a first source, and a first drain. The switch transistor has a second active layer, a second gate, a second source, and a second drain. The fingerprint recognition module also includes a first metal layer where the first source, first drain, second source, and second drain are located.

Original Abstract Submitted
The present disclosure relates to display assemblies, display apparatuses, and fingerprint recognition methods. One example display assembly includes a display panel and a fingerprint recognition module located on a light-emitting surface of the display panel. The fingerprint recognition module includes multiple fingerprint recognition units. Each fingerprint recognition unit includes at least one phototransistor and one switch transistor. The phototransistor includes a first active layer, a first gate, a first source, and a first drain. A material for making the first active layer includes an organic semiconductor material. The first drain and the first gate partially overlap to form a first capacitor. The switch transistor includes a second active layer, a second gate, a second source, and a second drain. The fingerprint recognition module includes a first metal layer. The first source, the first drain, the second source, and the second drain are all located at the first metal layer.
