  • Patent number: 7974168
    Abstract: A reproducing device includes a detection circuit and an integration circuit. The detection circuit detects a push-pull signal PP. The integration circuit carries out integration processing with respect to one or greater frames of the push-pull signal, and carries out binarization processing with respect to integration results thus obtained, thereby detecting sub data. In the integration circuit, the more the frames to be used for detecting sub data is, the higher the accuracy of the detected sub data is. The reproducing device further includes a control circuit for controlling the total number of the frames to be used for generating valid sub data in the integration circuit. The control circuit controls the total number of the frames in accordance with a result of an error correction made by an error correction circuit.

  • Publication number: 20110157097
    Abstract: A coordinate sensor (10) includes at least two line sensors (1) that are disposed in x-axis and y-axis directions, and right-angle prisms (2) each of which changes a light path of light that has passed through an image display region of a liquid crystal panel (20). Each of the line sensors (1) is disposed outside the image display region and has a light-receiving surface (1a) parallel to an image display surface of the liquid crystal panel (20). The right angle prisms (2) cause light which travels in the x-axis and y-axis directions and which has passed through the image display region to be guided to the light-receiving surfaces (1a) of the line sensors (1). The coordinate sensor (10) receives the light which has thus passed through the image display region of the liquid crystal panel (20) so as to detect a coordinate, on the image display region, that is indicated by an object to be detected such as a finger.

  • Publication number: 20110159632
    Abstract: The deposition temperature of the HDP film can be controlled to 365° C. or below, preferably within a temperature range of 335° C. to 365° C., and more preferably 335° C. to 350° C., or at 350° C. Thus, it becomes possible to suppress signal deterioration due to dark current and an increase in fine white defects, and to prevent deterioration of picture quality, even when the HDP film with a favorable embedding capability between fine wiring is used as an interlayer insulation film. An RF power is set to 850 W to 1500 W, so that dark current can be suppressed even more. Further, a plasma silicon nitride film with a refractive index of 1.9 or more and 2.15 or less for a blue wavelength is formed, so that it becomes possible to suppress the lowering of a blue sensitivity in the light receiving elements to further improve picture quality.

  • Publication number: 20110157481
    Abstract: A backlight unit 12 includes cold cathode tubes 18, a chassis 14 and connectors 22. Each cold cathode tube 18 has outer leads 18b at ends. The chassis 14 houses the cold cathode tubes 18. The connectors 22 are mounted to the chassis 14, connected to the outer leads 18b and configured to be movable relative to the chassis 14 in axial directions of the cold cathode tubes 18. When the cold cathode tubes 18 move relative to the chassis 14, the connectors 22 can move relative to the chassis 14 in the same directions. Therefore, frictions are less likely to occur in contact areas between the outer leads 18b of each cold cathode tube 18 and the respective connectors 22 and thus abnormal sounds or abrasions are less likely to occur.

  • Publication number: 20110157262
    Abstract: In a method of controlling power of a light emitting device for image display that irradiates illumination light from divided regions, light emission brightness data of each light emitting element of the light emitting device is determined based on image data for image display (S20). Power in each region and total light emission power are computed based on the light emission brightness data of each light emitting element for each region (S40). If the computed total light emission power exceeds predetermined allowable power, the power in each region is limited so that the total light emission power is equal to or less than the predetermined allowable power (S50).
