    摘要: A thin film transistor device and a method for preparing the same, an array substrate and a display device are disclosed. The thin film transistor device includes a first thin film transistor and a second thin film transistor coupled with each other. A first electrode of the first thin film transistor, a second electrode of the second thin film transistor, and a connecting line therebetween which is configured to couple the first electrode and the second electrode, are formed in a same layer, with each end of the connecting line being connected between respective ends of the first electrode and the second electrode opposite to each other. In the thin film transistor device, the first electrode and the second electrode are spaced apart from each other by a concave portion which is recessed in a region therebetween.

    摘要: A sealant dispensing apparatus includes a rotatable injection cartridge for loading a sealant, having a plurality of outlets distributed from a periphery to a center with respect to a rotation axis of the injection cartridge; and a nozzle assembly in fluid communication with the injection cartridge, including at least two sub-nozzles arranged in a line. The outlet of the injection cartridge closer to the center of the injection cartridge is in communication with the sub-nozzle of the nozzle assembly closer to a first end of the line, and the outlet of the injection cartridge closer to the periphery of the injection cartridge is in communication with the sub-nozzle of the nozzle assembly closer to a second end of the line. The first end is opposite to the second end.

    摘要: The disclosure provides a shift register, a driving method for the shift register, a gate driving circuit and a display device. The shift register comprises an input component, a reset component, a node control module, a chamfering control component and an output component. By setting the chamfering control component and cooperation among the above five components, an amplitude of a scanning signal output by a driving signal output terminal is changed so as to generate a scanning signal with a chamfered waveform. When the scanning signal with the chamfered waveform is sequentially input to each pixel unit in a corresponding row by a corresponding gate line, a jump voltage ΔVp on a pixel electrode of the pixel unit can be reduced, thereby mitigating phenomena such as flashing and image sticking of the display panel and improving the display quality of the display panel.

    摘要: The present disclosure provides a shift register unit and a driving method thereof, a gate driving device and a display device. The shift register unit includes an input circuit, an output circuit, a pull-down circuit, a first pull-down control circuit, and a second pull-down control circuit, wherein the second pull-down control circuit is provided with a first pull-down compensation transistor and a second pull-down compensation transistor and connected to a second power supply voltage, to compensate a threshold voltage drift of a second pull-down control transistor in the second pull-down control circuit so as to avoid abnormality of the shift register unit which would be caused by the threshold voltage drift of the second pull-down control transistor driven by a long-time high voltage, thereby ensuring the stability of the shift register unit.
