Abstract: A display device includes: a substrate including a display area including a plurality of pixels and a non-display area around the display area; data lines extending from the display area; a multiplexer in the non-display area and connected to the data lines; a display driving circuit in the non-display area and on one side of the multiplexer; and fan-out lines connecting the multiplexer and the display driving circuit, wherein the fan-out lines include first fan-out lines connected to the multiplexer and second fan-out lines connected to the first fan-out lines and the display driving circuit, and the first fan-out lines and the second fan-out lines are on different layers.

Abstract: An apparatus for treating a substrate includes a support unit including a support plate that supports the substrate and a rotary drive member that rotates the support plate and a lower fluid dispensing unit that dispenses a fluid onto a lower surface of the substrate supported on the support plate. The rotary drive member includes a hollow shaft coupled with the support plate and an actuator that rotates the hollow shaft. The lower fluid dispensing unit includes a fixed shaft that has an interior space and that is provided in the hollow shaft and a fluid dispensing tube that dispenses the fluid and that is provided in the interior space. An air-flow generation part is formed on an outer surface of the fixed shaft to generate a downward air flow in a space between the hollow shaft and the fixed shaft when the hollow shaft rotates.

Abstract: Disclosed herein is a self-diagnosis type welding carriage control system for automatically controlling welding conditions and implementing an oscillation motion. The welding carriage control system includes a main controller for a database, a remote control panel controller, a welding machine and condition controller, motion controllers for oscillation and travel motions, and a digital signal processing controller for managing memories for the respective controllers. The controllers are each provided internally with a central processing unit, and a dual port random access memory so as to share neighboring central processing units and memories through a versa module eurocard bus.
