  • Publication number: 20200166797
    Abstract: A display panel includes a substrate, a plurality of standard pixel units, and a plurality of dummy pixel units. A plurality of first conductor patterns and a plurality of shield blocks of a shield pattern layer are arranged in an array above the substrate. Each of the standard pixel units includes one of the first conductor patterns and a first shield block of the shield blocks. The first shield blocks and the first conductor patterns are overlapped, respectively. Each of the dummy pixel units includes a second shield block of the shield blocks. The second shield blocks and the first conductor patterns are not overlapped. A first edge of the substrate is spaced apart from a second edge of one of the standard pixel units adjacent to the dummy pixel units by a first distance. The first distance is within a range from 50 ?m to 3000 ?m.

  • Patent number: 5546326
    Abstract: This is a dynamic dispatching method for delivery performance by a factory. SLACK=(Due.sub.-- Date-Now)-(Forecast.sub.-- FAB.sub.-- Out.sub.-- Time); where Due.sub.-- Date=Scheduled due date from Master Production Schedule. The OTD (On Time Delivery) dynamic dispatching method focuses on the due date and the target cycle time under the environment of integrated circuit manufacturing. SLACK policy controls the long term due date and the OTD policy reflects the short term stage queue time. Through fuzzy theory, SLACK and OTD policies are combined as a dispatching controller to control the lot priority of the entire production line. The work piece, with either a long stage queue time, or with an urgent due date is pushed through the overall production line instead of jamming the front end of the process. A demand pull system satisfies the due date and the quantity of monthly demand.
