  • Publication number: 20230136052
    Abstract: A display device and a display system are provided with an anti-glare layer (AG layer) between a liquid crystal display on which to display a video and an optical device that is disposed at a position through which image light emitted from the liquid crystal display passes, has a reflective polarizing plate, and is capable of controlling reflectance/transmittance of incident light. Since light reflected by a color filter of the liquid crystal display is out of phase due to scattering in the AG layer, the degree of interference is reduced, leading to reduction in the appearance of an iridescent image due to interference light. In addition, since external light scattered or diffused by the AG layer and the reflected light of the external light do not have a polarization characteristic, and thus, most of a component thereof toward the outside is reflected by the reflective polarizing plate, which reduces a situation in which a region around a bright reflected image appears cloudy.

  • Publication number: 20230140328
    Abstract: A magnetic angle sensor outputs a component Vs in a Y direction where a vibration system of a synthetic vector of a magnetic vector of a magnetic circuit of a speaker and a magnetic vector of a displacement detection magnet fixed on the vibration system and a component Vc in an X direction orthogonal to the Y direction. A test signal is applied to the speaker, and collection of (Vs, Vc) and a measurement of a Y-direction displacement of the vibration system by a displacement meter are performed. A conversion equation “z=a1xVs+a2xVc” for the first principle component is obtained by principle component analysis on collected (Vs, Vc), and a conversion equation “y=b1xz2+b2xz+b3” for conversion to a displacement y is obtained by polynomial regression on the Y-direction displacement y of the displacement detection magnet obtained from a measurement value of the displacement meter and z calculated from collected (Vs, Vc).

  • Patent number: 11630628
    Abstract: When a screen to be displayed on a touch panel display includes no visual content for appreciation, such as a movie, the screen is displayed at a position closer to the user, at which the user can naturally manipulate the screen. When the screen includes a handwritten input acceptance box, the screen is placed at an upper position so that a handwriting input operation by the user is eased. When the screen includes visual content for appreciation, the screen is displayed at a position slightly distant from the user so as to be suitable for viewing the visual content for appreciation. The position suitable for appreciation is set according to the display size and resolution of the visual content, included in the screen, for appreciation.

  • Publication number: 20230057212
    Abstract: A detection unit has a fixed magnet, which is part of a magnetic circuit unit, and also has a movable magnet and a magnetic sensor, which are disposed below a cap. A fixed magnetic field component oriented toward a vibration direction acts on the magnetic sensor due to a leakage flux from the magnetic circuit unit. A movable magnetic field component acts from the movable magnet on the magnetic sensor in a direction crossing the fixed magnetic field component. A change in the angle of a detection magnetic field component, which is a combined vector formed from the magnetic field components in two directions, is detected by the magnetic sensor. According to the output in this detection, the operational position of the movable magnet is measured.
