  • Publication number: 20060163597
    Abstract: It is an object of the present invention to provide a high-contrast light-emitting device without using a polarization plate. In particular, it is an object of the present invention to make contrast control simpler for a light-emitting device provided with a color filter. A light-emitting device according to the present invention has a feature of having a structure for reducing reflection of light from a light-emitting later at a reflective electrode, and further, has a feature of absorbing wavelengths other than the light by a color filter to enhance the contrast. Accordingly, contrast control can be performed in consideration of only a luminescence component from the light-emitting layer, and is thus made simpler.

  • Publication number: 20060158458
    Abstract: It is an object of the invention to provide a display device which performs high grayscale display in accordance with display contents and a game machine with an improved realistic sensation. The invention is a display device characterized by including a pixel portion which performs display based on a video signal and a driver circuit portion inputted with the video signal, wherein the driver circuit portion has a unit for controlling a grayscale in accordance with display of the pixel portion. In a liquid crystal display device, luminance of a lighting unit is controlled based on a signal from the unit for controlling a grayscale whereas a current supplied to a light emitting element is controlled in a light emitting device. By applying such a display device to a game machine, a realistic sensation can be improved.

  • Publication number: 20050168339
    Abstract: In commercial products to which a non-contact type or contact type ID label or ID tag is attached and ID cards, there is fear that, due to a difference between coefficients of thermal expansion between an antenna for communication and a resin provided around the antenna, stress is applied to the resin with the larger coefficient of thermal expansion to break the resin. This contributes to decrease in manufacturing yield, lifetime, and reliability of an ID label or the like. In an article such as an ID label, an ID tag, and an ID card according to the present invention, a filler is included in a filling layer provided around an antenna forming an ID label, an ID tag, and an ID card so that the difference in coefficient of thermal expansion between the antenna and the filling layer can be reduced. This makes it possible to ease generation of stress due to the difference in coefficient of thermal expansion and prevent peeling and cracks of the filling layer.

  • Publication number: 20040245525
    Abstract: A device having an integrated circuit, especially an IC card, for reliably verifying a person's identity by display of PIN numbers or passwords with ingenuity. Portable electronic devices such as a PDA or a cellular phone, or other products can have plural displays in a display area (display part) provided in a limited area. A first display area and a second display area having transparency are stacked together in a thin film integrated circuit device of the present invention. The area of display can be reduced and display of more complicated PIN numbers or passwords is enabled by layering the display of the first display area and the display of the second display area.

  • Publication number: 20040164302
    Abstract: The present invention provides an ultrathin thin film integrated circuit and a thin film integrated circuit device including the thin film integrated circuit device. Accordingly, the design of a product is not spoilt while an integrated circuit formed from a silicon wafer, which is thick and produces irregularities on the surface of the product container. The thin film integrated circuit according to the present invention includes a semiconductor film as an active region (for example a channel region in a thin film transistor), unlike an integrated circuit formed from a conventional silicon wafer. The thin film integrated circuit according to the present invention is thin enough that the design is not spoilt even when a product such as a card or a container is equipped with the thin film integrated circuit.
