The communications terminal includes: a terminal body; a case coupled to the terminal body to form an exterior of the terminal; and an antenna part including an antenna pattern integrally formed with the case and an elastic pin formed at one end of the antenna pattern to be electrically connected to a wireless module provided in the terminal body.
Abstract:
According to example embodiments, a maskless exposure apparatus includes a light source array including a plurality of light sources, a focusing element array including a plurality of focusing elements, and an image forming lens unit between the focusing element array and a substrate. The focusing element array is configured to perform a first focusing operation to focus light beams emitted from the plurality of light sources. The image forming lens unit is configured to perform a second focusing operation on the focused light beams to form focused light spots on the surface of the substrate. The focused light spots form a pattern on the substrate.

There are provided an electronic device having a transmission line pattern embedded in a case and a method for manufacturing the same. The electronic device includes a line pattern body embedded in a case and including a line pattern for electrically connecting components to each other, terminal portions respectively disposed at portions of the line pattern corresponding to terminals of the components to be electrically connected, and exposed from the bottom of the case, and connection members connecting the terminals of the components with the terminal portions.
Abstract:
Disclosed herein are a maskless exposure apparatus configured to perform exposure by tilting a beam spot array with respect to a scan direction (Y-axis direction) thus preventing stitching stripes and a stitching method using the same. A step distance, in which exposure dose uniformity in a stitching area is within a tolerance range, is calculated using actual position data of beam spots constituting the beam spot array on an exposure plane, and if necessary, using beam power data and/or beam size data. As exposure is performed based on image data conforming to the step distance, the stitching area has a uniform exposure dose, enabling exposure without stitching stripes.
Abstract:
A digital exposure method and a digital exposure device for performing the method are disclosed. In the method, a graphic data system file is produced in correspondence with each of a plurality of patterns formed on a substrate. Then, a digital micromirror device on/off data is generated from the graphic data system file. Then, the substrate is exposed in response to the digital micromirror device on/off data. Thus, at least a first exposure for forming a first pattern of a display panel, and a second exposure for forming identification numbers of a substrate and each display panel and removing an edge portion of the substrate may be simultaneously performed, to simplify the exposure process decrease costs.
