摘要:
A semiconductor device, comprising a substrate, a plurality of polysilicon portions formed on the substrate, wherein the polysilicon portions are spaced apart from each other, a plurality of source/drain regions formed in the substrate between adjacent polysilicon portions, and a dielectric layer formed on the polysilicon portions and on the source/drain regions, wherein the dielectric layer includes a cavity filled with conductive material to form a contact area, the contact area overlapping part of a source/drain region and part of a polysilicon portion to electrically connect the polysilicon portion with the source/drain region, and wherein part of the contact area extends below an upper surface of the substrate to contact an implant region with the same doping as the source/drain region. The implant region is next to the source/drain region and includes part of a channel region in the substrate under the polysilicon portion.

In a driving method of a display apparatus using a driving circuit, when an image signal is a film image signal, first, second, and third original image signals are extracted based on the film image signal. Then, a first compensation image signal is generated based on first and second original image signals, and a second compensation image signal is generated based on second and third original image signals. The first original image signal, the first compensation image signal, the second original image signal, and the second compensation image signal are sequentially output to have a driving frequency higher than an input frequency. In addition, the first original image signal, the first compensation image signal, the second original image signal, and the second compensation image signal are output i, k, j, and k times, respectively. Thus, a trembling phenomenon perceived by a viewer of a film image may be prevented.

Disclosed is a system and a method for collecting various road traffic information, road image information, and position information of a position information generation device carried by an object, the position of which is to be tracked, by interworking with an information provision means and using the collected information to provide service subscribers with real-time traffic information, traffic prediction, or position information of the object via wireless Internet, satellite broadcasting, DMB, or cable data broadcasting. The system and method can provide detailed traffic information service regarding a specific region or location on a nationwide scale, predict traffic to properly deal with it, and easily provide position information of an object to be tracked.
摘要:
A display device with improved display quality and a method of driving the display device set at least one static area in each of a previous frame and a current frame by comparing edge areas of the previous frame and edge areas of the current frame, and create an interpolated frame for display between the previous and current frames. At least one static area of the previous frame is used in an unmodified state as a static area of the interpolated frame.

A wireless and multi-channel re-transmitting link is provided between an image displaying part that is housed in a first housing and an image data processing part that is housed in a segregated second housing. The wireless link allows the image displaying part to be more easily moved around and to be made lighter and slimmer in profile because at least some image data processing can be carried out in the second housing and yet cumbersome cables are not needed for linking the pre-processed image data from the second housing to the first housing. In one embodiment, the data bandwidth. that is to he transmitted through the wireless link is first reduced; for example the frame refresh rate of image frames conveyed through each of the wireless channels is made less than the frame refresh rate of the original image signal. In one embodiment, the reduced number of frames per unit time are further frequency wise and temporally wise spaced apart from one another by alternatingly sending them through different wireless channels at different times. Thus if a burst of noise strikes one of the plural re-transmission channels, the likelihood that it will corrupt a frame is reduced.

A semiconductor memory device includes a plurality of word lines, a plurality of pairs of bit lines and complementary bit lines, and a plurality of memory cells, each memory cell being disposed at a region where a respective word line and a pair of a bit line and a complementary bit line cross each other. A voltage control unit controls a power voltage to obtain a controlled voltage appliable to the memory cells in response to a control signal that controls an operation of the memory cells. At least one dummy cell is disposed between the voltage control unit and the memory cells and is configured to reduce the controlled voltage to a predetermined level.
