    摘要: 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.

    摘要: 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.

    摘要: 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.
