Disclosed are a display apparatus and an image displaying method, which can increase a battery usage time. The display apparatus includes a display including a screen for displaying an image; and a controller configured to provide the display a first user interface (UI) for selecting at least one among a plurality of regions in the screen, provide the display a second UI for adjusting a displaying position of the image to be displayed on at least one region selected through the first UI, and control the display to display the image at the displaying position adjusted through the second UI, and make the other regions of the screen except the region where the image is displayed be in a power-saving mode. According to the present invention, it is possible to not only increase a battery usage time but also display information at a position desired by a user.

Display apparatus and image displaying method

An apparatus for inspecting a collimator including a pigtail formed with first and second fibers, a GRIN lens disposed coaxially relative to the pigtail, and a glass tube supporting the pigtail and the GRIN lens in a single unit, to inspect optical properties of the collimator, comprising an inspection table; a gripping part, which is provided on the inspection table, gripping the collimator subject to inspection; a light supplying part transmitting a predetermined optical signal to the first fiber; a light receiving part, which is connected to the second fiber, receiving an optical signal returned from the second fiber, entering the first fiber; a measuring part calculating a value of the predetermined optical signal, which entered the first fiber, and a value of the optical signal, which returned from the second fiber; and an image displaying part displaying the value obtained from the measuring part. With this configuration, the collimator can be inspected in part, thereby increasing the product reliability of the collimator.

Apparatus for inspecting collimator

An apparatus for inspecting a collimator including a pigtail to which a fiber is connected to transmit an optical signal, a GRIN lens coaxially arranged with the pigtail, a glass tube accommodating and supporting the pigtail and the GRIN lens, and a metal sleeve protecting the glass tube, comprising an inspection table; a grip part provided on the inspection table, and gripping the collimator to be inspected; a first camera provided over the grip part having an axis perpendicular to a length of the collimator, and photographing the collimator along the length of the collimator; a second camera arranged coaxially with the collimator on the inspection table, and photographing the collimator perpendicular to an axis of the collimator; and a displaying part connected to the first and second camera, and displaying pictures transmitted from the first and second cameras. With this configuration, an apparatus for inspecting a collimator, which can effectively inspect the collimator, is provided, thereby increasing the reliability of the collimator.
