Abstract:
Disclosed is a pressure sensor comprising: a substrate; a pressure reception plate which is provided in a state of facing the substrate, the pressure reception plate comprising in a surface which faces the substrate, a low reflection region, and a high reflection region having a relatively higher reflection ratio compared to the low reflection region; a support portion to change a distance between the substrate and the pressure reception plate when a pressure is applied to the pressure reception plate, the support portion being provided in between the substrate and the pressure reception plate; and a plurality of light receiving elements which are respectively provided on the substrate in positions facing the low reflection region and in positions facing the high reflection region, of the pressure reception plate.
Abstract:
A display apparatus includes a liquid crystal display panel and an illuminator disposed at the back of the panel for emitting at least two illumination lights having directivities in different directions toward the panel. The illuminator includes a light guide plate made of transparent material whose one end surface serves as a light entrance end surface, whose one plate surface serves as a light exit surface, and whose other plate surface serves as a light direction changing surface for changing the advancing direction of light entering from the light entrance end surface. The light direction changing surface has a plurality of circular-arcing slanted surfaces shaped into semicircles formed on concentric circles centered at the center of the longer dimension of the light entrance end surface. Light emitting elements are disposed on the light entrance end surface at two positions on left and right sides of the center equidistantly apart therefrom.
Abstract:
A display apparatus for displaying a three-dimensional image using a parallax barrier scheme includes a display module having a display region in which a plurality of pixels are arranged, and a parallax barrier facing the display region. In the parallax barrier, a plurality of aperture regions are formed as light-transmissive regions so that each one of the aperture regions corresponds to a predetermined number of the pixels. In one embodiment, each of the aperture regions is in a shape that exhibits an identical shape when rotated by 90 degrees.
Abstract:
A three-dimensional image viewing device includes a control panel in which a plurality of pixels are disposed in a predetermined region; a position identifying unit that identifies a right eye position and a left eye position of a user viewing a display screen on which a left eye image and a right eye image are displayed through the predetermined region of the control panel configured to be interposed between the user and the display screen; and a control circuit that controls the plurality of pixels such that at least part of the pixels arranged in a region corresponding to the right eye position identified by the position identifying unit transmits light only from the right eye image and also such that at least part of the pixels disposed in a region corresponding to the left eye position identified by the position identifying unit transmits light only from the left eye image.
