Abstract: A mask assembly configured to prevent the mask from being thermally transformed and to maintain gaps between a plurality of divided pattern masks is disclosed. According to one embodiment, the mask assembly comprises: an open mask that has a plurality of first openings arranged in rows and columns; and a pattern mask that comprises a plurality of unit pattern masks. In some embodiments, the ends of the unit pattern masks may be fixed with respect to the open mask, and the unit pattern mask includes a plurality of mask pattern units configured to align with the plurality of first openings of the open mask. In some embodiments, a tensile force is applied to the unit pattern mask(s).

Abstract: A mask for depositing a thin film of a flat panel display and a method of fabricating the mask are disclosed. Embodiments of the mask can improve position accuracy and prevent problems caused by thermal expansion of the mask by attaching a reinforcing member and mask pattern units arranged on openings of the reinforcing member using a buffer member. The mask includes a reinforcing member including a plurality of first openings; mask pattern units arranged corresponding to the first openings of the reinforcing member and supported by the reinforcing member; and a buffer member including a plurality of second openings corresponding to the first openings of the reinforcing member, and attaching the reinforcing member to the mask pattern units to support the reinforcing member and the mask pattern units.

Abstract: A mask device, a method of fabricating the mask device with improved reliability, a method of manufacturing a large-sized division mask device by forming a striped aperture parallel to the roll direction, and a method of fabricating an organic light emitting display device (OLED) using the mask device. The mask device includes: at least one mask alignment mark formed on a mask; a blocking region formed on the mask and blocking a deposition material; and an aperture region formed on the mask and through which the deposition material passes, wherein the at least one mask alignment mark is formed outside the aperture region, the aperture region has a stripe pattern, and the roll direction of the mask substrate is parallel to the longitudinal direction of the stripe pattern.

Abstract: Provided is a method of descaling a mask that quickly and effectively removes a material attached to the mask. The method includes: directing a laser beam onto a material attached to the mask; and removing the material attached to the mask.

Abstract: A context generation circuit for a small screen, and a method therefor, are provided. The circuit can generate a context with respect to an image that is larger than the horizontal size of a context using two-line and three-line templates, and also combine the position of a modified two-line template or modified three-line template overlapping an input image with the corresponding space in a register. Also, the circuit generates a context by inserting an arithmetic “0” into the position of the modified two-line template or modified three-line template which does not overlap the image. Therefore, an image having a small horizontal size can be effectively processed, and the circuit operates at high speed, and is reliable.

Abstract: A priority order processing circuit is disclosed for an MPEG system adapted to determine the priority order of events generated from a multiprocessor of a decoding system utilizing MPEG1 and MPEG2 schemes while controlling operations of the system.

Abstract: A circuit for restoring an image signal using motion compensation is disclosed, which includes an index address generator for storing and selectively generating a start address for each image, an adder for adding the start address generated by the index address generator to an address of a current macroblock to be processed and generating a pseudo address, an address calculator for calculating an address displacement from a motion compensation vector, and an address generator for adding said pseudo address to the address displacement to generate start and end addresses.
