Patent number: 8199306Abstract: A printed circuit board (PCB) includes a base substrate, an electrical wiring, a dummy pad and a thermally conductive adhesion member. The base substrate includes a light-emitting diode (LED) mounted on a first surface of the base substrate. The electrical wiring is electrically connected to the LED. The dummy pad is formed on the first surface to be connected to the electrical wiring. The thermally conductive adhesion member is attached to a second surface of the base substrate. Therefore, superior heat radiation may be obtained, thereby reducing or preventing damage to the LED and the LCD device using the LED by radiating the heat from the LED used as a light source.Type: GrantFiled: December 23, 2008Date of Patent: June 12, 2012Assignee: Samsung Electronics Co., Ltd.Inventors: Gwan-Hyoung Lee, Young-Bee Chu, Sang-Hee Lee, Jeong-Seok Oh, Young-Soo Kim, Wal-Hee Kim

Patent number: 8106889Abstract: A touch-screen display device includes a display panel, a touch panel, and an adhesive member. The display panel has a peripheral area surrounding an effective area. The touch panel is separated from and faces the display panel. The adhesive member has an adhesive part disposed along the peripheral area and an airing portion disposed along a portion of the peripheral area. The adhesive part adheres the touch panel and the display panel together. The airing portion blocks a particle from entering into a space between the touch panel and the display panel, and inflows and outflows air from the exterior to the space. Therefore, the touch panel and the display panel are coupled by the adhesive member having an airing portion formed thereon, so that a display error may be prevented.Type: GrantFiled: October 5, 2006Date of Patent: January 31, 2012Assignee: Samsung Electronics Co., Ltd.Inventors: Se In Chang, Wal Hee Kim, Sang Hee Lee
