The circuit component is formed corresponding to the first opening. | 10-02-2008 |
20090180047 | DISPLAY DEVICE - A display device includes a display panel displaying an image, a driving circuit substrate electrically connected to the display panel and having a contact member mounted on one side thereof, a frame accommodating the display panel and the driving circuit substrate and having a through hole, and an accommodating member arranged below the frame and coupled to the frame, wherein the contact member contacts the accommodating member through the through hole. | 07-16-2009 |
20090296423 | BACKLIGHT ASSEMBLY AND DISPLAY DEVICE HAVING THE SAME - One or more embodiments of a backlight assembly include a light guide plate (LGP), a light source module and an optical sheet. The LGP includes a side surface and an upper surface. The light source module includes a power-transmitting member and a plurality of point light sources disposed on the power-transmitting member. A side portion of the power-transmitting member is disposed on a peripheral portion of the upper surface adjacent to the side surface and a light-exiting surface of the point light sources facing the side surface to be adjacent to the side surface. The optical sheet is disposed on the upper surface. A portion of the optical sheet is disposed between a corner portion of the upper surface and the power-transmitting member adjacent to the light-exiting surface. The amount of the light absorbed by a reflective member may be decreased to improve the efficiency of the light. | 12-03-2009 |

20110004769 | PASSWORD INPUT SYSTEM USING AN ALPHANUMERIC MATRIX AND PASSWORD INPUT METHOD USING THE SAME - The present invention relates to a password input algorithm, more particularly to a password input system and method using an alphanumeric matrix. An aspect of the invention can provide a password input system and method that can defend against keylogging attacks and shoulder surfing attacks, by having the final password inputted by way of certain alphanumeric matrix letters which are separated by a particular distance from the letters forming the password in the alphanumeric matrix. Also, an aspect of the invention can provide a password input system and method that can further increase the probability of defending against keylogging attacks and shoulder surfing attacks, by having the final password inputted by way of certain alphanumeric matrix letters which are separated by a particular distance from the letters forming the password in the alphanumeric matrix, but with the alphanumeric matrix rotated every time a letter is inputted. | 01-06-2011 |
20110004928 | PASSWORD INPUT SYSTEM USING ALPHANUMERIC MATRICES AND PASSWORD INPUT METHOD USING THE SAME - The present invention relates to a password input algorithm, more particularly to a password input system and method using alphanumeric matrices. An aspect of the invention can provide a password input system and method using alphanumeric matrices that can defend against keylogging attacks and shoulder surfing attacks by including a movable second alphanumeric matrix and a fixed first alphanumeric matrix and enabling a user to input a password by moving the password letters of the second alphanumeric matrix to the user-defined value of the first alphanumeric matrix. Another aspect of the invention can provide a password input system and method using alphanumeric matrices that can defend against shoulder surfing attacks by enabling a user to input a password by dividing the password by every two digits and moving the cross-points for the two digits, respectively, to the user-defined value of the first alphanumeric matrix. | 01-06-2011 |
