Abstract: A semiconductor device, including a substrate; a first conductive type well and a second conductive type body region at an upper portion of the substrate; a field plate on the first conductive type well, the field plate including a semiconductor material or an insulative nitride; and a gate electrode extending in a lateral direction on the substrate from a lateral portion of the second conductive type body region to a lateral portion of the first conductive type well, the gate electrode overlapping the field plate.

Abstract: An image display device and an operation method thereof are provided. An object may be displayed on a display. A display characteristic of the object may be changed when no input for the object is received for a predetermined period of time.

Abstract: Provided is an image display device. The image display device includes an interface, a memory, a controller, and a display unit. The interface supports communication with an external storage medium, and the memory stores data transmitted through the interface. The controller compares attribute information of data stored in the memory with that of data stored in the external storage medium when the external storage medium is connected through the interface and controls changing of a data name of data stored in the memory or a data name of data stored in the external storage medium depending on whether the attribute information is identical. The display unit displays whether a data name is changed in response to a control signal from the controller.

Abstract: A process for preparing a black matrix comprising the steps of producing a developed substrate by coating, drying, exposing and developing a photoresist on the inside of a substrate, producing a dried substrate by drying the developed substrate several times, coating a dye on the dried substrate and then drying the board, coating graphite on the dried substrate, and etching the graphite-coated substrate. This method makes it possible to perfectly etch the black matrix dot and increase volatility in fluorescent coating.
