Methods and apparatus for supporting dual casting of inbound system memory writes from PCIe devices to memory and a peer PCIe device. The present invention can solve the problem that turn-on and turn-off of a switching thin film transistor and grayscale control cannot be performed effectively because the switching thin film transistor and a driving thin film transistor are manufactured as thin film transistors having same performance parameters in an existing OLED array substrate. reactive metals or reactive metal compounds, and a combination of two or more of any of through, the components of having been reacted with the carboxylated isobutylene-polyene copolymer simultaneously or sequentially, in any order. The top surface intersects the front raised surface and each of the side raised surfaces. The method may be reversed in order to change over the truck from carrying a trailer body to a dump body.
