  • Patent number: 9703104
    Abstract: As an electro-optical device, a liquid crystal device includes micro lenses ML each of which is provided as a light-gathering element for the corresponding one of pixels, and further includes a light-shielding portion. Red (R), green (G), and blue (B) beams enter the micro lens ML at angles different from one another. The light-shielding portion partitions off a first opening portion corresponding to a sub pixel, a second opening portion corresponding to a sub pixel, and a third opening portion corresponding to a sub pixel from one another. When the width of the first opening portion in the predetermined direction (X direction) is defined as L1 and when the width of the second opening portion or the third opening portion in the predetermined direction is defined as L2, a relationship of L1<L2 holds true.

  • Publication number: 20170031443
    Abstract: A system and method are disclosed in which in a conventional non-grounding man-machine interface having no reaction base on the human body and for giving the existence of a virtual object and the impact force of a collision to a person, a haptic sensation of a torque, a force and the like can be continuously presented in the same direction, which cannot be presented by only the physical characteristic of a haptic sensation presentation device. In a haptic presentation device, the rotation velocity of at least one rotator in the haptic presentation device is controlled by a control device, and a vibration, a force or a torque as the physical characteristic is controlled, so that the user is made to conceive various haptic information of the vibration, force, torque or the like.

  • Patent number: 9460652
    Abstract: According to one embodiment, a display device displays an n?1th frame (n is an integer which is greater than or equal 2) and an nth frame in this order. The display device includes a display panel, calculator, adjuster, and controller. The calculator calculates power consumption of the n?1th frame. The adjuster determines whether or not the nth frame is brighter than the n?1th frame, and adjusts brightness of the nth frame based on a brightness adjustment magnification of the nth frame calculated based on the power consumption of the n?1th frame and a decreasing function, when the nth frame is not brighter than the n?1th frame. The controller stops light emission with an arbitrary timing when the nth frame is displayed, when the nth frame is brighter than the n?1th frame.

  • Publication number: 20150012414
    Abstract: The purpose of the present invention is to provide an electronic money server that supports regular periodic payments using electronic money. On the electronic money server, a payment debt is created in association with an electronic money function section ID (S105). A “transaction ID” is also determined at that time. An electronic money application on a portable terminal sends the electronic money server a payment debt request to ascertain whether or not a payment debt exists (S115). If a payment debt exists and the due date thereof has been reached (S120; Y), the electronic money server sends the portable terminal a payment connection request (S130) and requests authorization from the user. If the user sends an “approval” notification to the electronic money server (S135), the electronic money server sends a payment request by sending a subtraction command to an IC chip in the portable terminal (S140).
