    Abstract: An apparatus and a method for determining an overlap distance of an optical head is disclosed. Positions and light amount distributions of each light spot can be measured, which may be provided from an optical head to a substrate. Gaussian distribution may be applied to the positions and the light amount distributions to calculate a compensation model of each of the light spots. A first accumulated light amount corresponding to each first area of the substrate may be calculated if the optical head is scanning along a first direction of the substrate using the compensation model. A second accumulated light amount corresponding to each second area overlapped with the each first area is calculated if the optical head is scanning along the first direction, which is moved in a second direction by a first distance using the compensation model. An overlap distance may be determined based on a uniformity of summations of the first and second accumulated light amount.

    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.

    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.
