Patent number: 7725988Abstract: Disclosed are a hinge assembly and a mobile device having the hinge assembly. In the mobile device, a rotation portion 14 slides and rotates on a base portion 10, so as to be inclined to the base portion 10. For this reason, the rotation portion 14 is connected to the base portion by means of the hinge assembly 20 so as to slide and rotate on the base portion 10. The rotation portion 14 slides on the base portion by a predetermined distance, and then rotates to be inclined at a desired angle with respect to the base portion 10. The rotation portion 14 easily rotates with respect to the base portion of the mobile device, so that the status of the mobile device can be easily converted. Further, when the status of the mobile device is converted, the front, rear, left and right of a display screen is not changed. As a result, the mobile device should not have a structure of changing a display direction of the display screen.Type: GrantFiled: February 14, 2007Date of Patent: June 1, 2010Assignee: LG Electronics Inc.Inventors: Yun Tae Kim, Kwang Soo Kim, Seung Don Lee, Hyun Suk Yang, Ji Yeon Lee, Jeong Rok Lee

Publication number: 20060082825Abstract: An apparatus for processing print-data according to a print-mode set on a connected printing device in order to print the print-data according to the print-mode and a method thereof are disclosed. The print-data processing method includes the steps of: a) setting a print-mode; b) receiving the print-mode; c) performing a predetermined transforming process on the print-data according to the received print-mode; and d) transmitting the transformed print-data to the printing device. Accordingly, the printing device is prevented from performing a faulty printing process caused by the print-data transforming process.Type: ApplicationFiled: October 17, 2005Publication date: April 20, 2006Inventor: Seung-don Lee

Patent number: 7021734Abstract: An inkjet printer, a system thereof and a method of compensating for deteriorated nozzles. The inkjet printer has an input unit to select a printing workload share for nozzle groups with respect to an image writing unit area, each nozzle group including a plurality of nozzles; and a control unit to control the print head according to the printing workload share selected by the input unit, thereby causing the image data to be printed onto the recording medium. Since the printing workload share for the defective nozzles is reduced, print quality deterioration can be prevented without having to replace a print head.Type: GrantFiled: January 17, 2003Date of Patent: April 4, 2006Assignee: Samsung Electronics Co., Ltd.Inventor: Seung-don Lee

Publication number: 20060007462Abstract: Disclosed is a method and apparatus for printing an image without borders. In the method, an image to be printed is divided into at least two image regions and these image regions are expanded and printed using different image expansion methods. The method comprises the steps of dividing the image into at least two image regions, computing the values of expansion pixels of the image regions using image expansion methods corresponding to the respective image regions, expanding the image using the computed values, and printing the expanded image.Type: ApplicationFiled: April 6, 2005Publication date: January 12, 2006Inventor: Seung-don Lee
