  • Patent number: 11402709
    Abstract: A repairing method for an array substrate is provided. The array substrate includes at least one defective signal line, which is a data line or a gate line having a breakpoint. The defective signal line is divided by the breakpoint into a first portion and a second portion. The repairing method includes disconnecting a connection between a first thin film transistor and a data line or a gate line to which the first thin film transistor is connected, the first thin film transistor being a thin film transistor closest to the breakpoint among thin film transistors connected to the first portion; electrically connecting a first terminal of the first thin film transistor to the first portion; and taking a common electrode line segment from a common electrode line to which the first pixel electrode corresponds as a repair line.

  • Patent number: 10908467
    Abstract: The present disclosure provides an array substrate and a method for repairing the same, and a display panel. The array substrate includes gate lines extending in a first direction, and data lines and common electrode lines extending in a second direction. The gate lines intersect with the common electrode lines and the data lines to define pixel units. Every two adjacent pixel units at two sides of a common electrode line constitute a pixel unit group. Common electrodes of two pixel units in a pixel unit group are each connected to a common electrode line therebetween. The array substrate further includes a repairing structure including a first repairing line, a second repairing line at two sides of a data line, respectively, and a middle line intersecting with the data line and connecting a first point of the first repairing line and a second point of the second repairing line.

  • Patent number: 10556973
    Abstract: Disclosed is a process for making nitrated styrenic fluoropolymers having various degrees of substitution. The nitrated styrenic fluoropolymer is capable of providing an exceptionally high birefringence ranging from 0.02 to 0.036. Further, the birefringence can be tuned by varying the degree of substitution (DS) of the nitro group on the styrenic ring to meet the need for optical compensation film applications. More particularly, the optical compensation films of the present invention are for use in an in-plane switching LCD (IPS-LCD) and OLED display.

  • Patent number: 6923891
    Abstract: A method for forming a conductive region on a first portion of a substrate, the method being constituted by exposing the first portion to a filtered beam of substantially fully ionised metallic ions under a pulsed, modulated electrical bias. The method uses FCVA (Filtered Cathodic Vacuum Arc) techniques to generate the filtered ion beam and permits the formation of a conformal metal coating, even in high aspect ratio visa and trenches. The method also permits the in-filling of vias and trenches to form conductive interconnects. Particular examples concern the deposition of copper ions. An adapted FCVA apparatus deposits metals on substrates. A control apparatus controls ion beams impacting upon substrates, the control apparatus being suitable for incorporation within existing filtered ion beam sources.
