Abstract: A demultiplexer gate driver circuit and a display panel are provided. The demultiplexer gate driver circuit aims at the problem that the output amplitude of the m sub-gate drive signals divided from the gate drive signal by the demultiplexer module is low, which results in a poorer All Gate On function, when the GOA circuit of the demultiplexer module is used to achieve the All Gate On function. The full-on control module is improved by connecting the full-on control module to the m sub-gate drive signals divided from the gate drive signal. The m sub-gate drive signals are directly controlled by the full-on control module to output the high potential at the same time, and there is only one threshold voltage consumption from the full-on control signal to the sub-gate drive signals. The effect of the All Gate On function is effectively improved.

Abstract: An array substrate and a method of manufacturing thereof are provided. The array substrate includes a substrate, a buffer layer, a plurality of thin film transistors, an organic layer, and a first electrode. By defining a via hole between two adjacent thin film transistors in the bending region, the via hole penetrates through the passivation layer, the gate insulating layer, and the first metal trace, which can effectively reduce stress between the passivation layer and the gate insulating layer.

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.

Abstract: A 3D display device and a manufacturing method thereof are provided. Metal nanowires perpendicular to each other are provided at the TFT glass substrate side and the CF glass substrate side. The metal nanowires can realize inherent function of polarizers at the TFT glass substrate side and the CF glass substrate side, and can also make the emitted light into stripe-shaped polarized light perpendicular to each other. Therefore, the polarizers, the λ/2 phase retarder with stripes, and the polarizers with stripes and perpendicular polarization that are originally at the TFT glass substrate side and the CF glass substrate side in a 3D polarizer display are excluded. The thickness of the 3D display device is made thinner. Moreover, according to the structural design, polarization effect is not limited by wavelength range of the light. Therefore, 3D stereoscopic display effect is greatly enhanced.

Abstract: A fixing jig is provided, including a supporting base, a fixing plate, and a fixing component. The supporting base includes a first upper surface. The fixing plate is disposed on the supporting base. A side of the fixing plate is pivotally connected to the supporting base and includes a second upper surface, a bottom surface, and via a hole. The fixing component presses the fixing plate on the second upper surface. The fixing jig can fix an object pending testing and allows one flexible electric circuit board of the object pending testing to be exposed outside of the fixing jig, so that when performing a pull force test, this can allow an angle between two flexible electric circuit boards to be 90 degrees, thereby improving accuracy of an experimental result.
