Abstract
Example embodiments are directed to a maskless exposure apparatus to efficiently process frame data of a Digital Micro-mirror Device (DMD) and a frame data processing method thereof. The frame data includes data obtained when a reference pixel of a virtual mask of the DMD and subsequent pixels of the virtual mask of the DMD, each of said subsequent pixels having an exposure time succeeding an exposure time of the reference pixel, are located on the same line. The generated frame data is selectively time-delayed and is changed to exposure frame data, and a pattern is exposed on a substrate using the exposure frame data.
