Abstract: An antenna system for use in a communications device, such as a mobile phone. The antenna system has a multiband GSM antenna operating at GSM850, GSM900, GSM 1800 and GSM 1900 that has a short-circuited section located between a separate UMTS antenna and a UMTS receive diversity antenna. As such, large electrical isolation between the two UMTS antennas can be achieved. The UMTS antennas can be short-circuited microstrip loop antennas, IFA, PIFA, ILA or PILA antennas. These antennas are well-isolated antennas instead of coupled antennas. As such, the diversity antenna is well isolated from the main antenna despite its close proximity to the main antenna. Well-isolated antennas have little mutual coupling and, therefore, are easier to design than coupled antennas, because isolated antennas can be tuned independently from each other.

Abstract: In an active matrix display device using an SRAM, the number of transistors configuring the SRAM circuit is large. Therefore, the transistors cannot be embedded in a pixel when a pixel area is small, otherwise an aperture ratio is reduced. In view of the foregoing, it is an object of the present invention to provide a display device without a refreshing operation and thus with small power consumption. According to the invention, a display device including a pixel which comprises a switching element and a nonvolatile memory element is provided. When a still image is displayed by utilizing a ferroelectric element as a nonvolatile memory element and storing a signal, writing is not required per frame. Further, as the ferroelectric element occupies a small area, a memory circuit can be incorporated without decreasing an aperture ratio.

The lighting of each pixel is altered by altering a surface normal of the pixel using a value obtained from each of one or more normal maps. Normal maps are selected by using wrinkle ratios that are calculated based on the above mentioned comparisons.
