Abstract: A gate driver on array (GOA) device and a display panel are provided. The GOA device includes multi-level cascaded GOA units. Each level of the GOA units comprises a first sub GOA unit and a second sub GOA unit. The first sub GOA unit is configured to output a first scan driving signal. The second sub GOA unit is configured to output a second scan driving signal. The first sub GOA unit and the second sub GOA unit share at least a portion of signal wirings, so that a width of the GOA device is narrowed while a circuit layout of the display panel is simplified.

Abstract: A piezoelectric polyvinylidene fluoride (PVDF) material, a method for manufacturing the same, and a fingerprint recognition module are provided. The polyvinylidene PVDF material includes PVDF, a first solvent, a second solvent, a fluorosurfactant, and an inducing material. Material of the inducing material is one of carbon nanotubes, carbon black, and gold nanorods. Because of the high anisotropy of the inducing material, molecular orientation of the PVDF material is induced, thereby improving piezoelectric performance of the piezoelectric PVDF material. Problems of conventional piezoelectric PVDF materials, which are used in ultrasonic fingerprint recognition modules, such as poor piezoelectric performance and high-energy loss are improved.
