Publication number: 20240099085Abstract: A display device includes a pixel. The pixel is electrically connected to a first power line, a second power line, and a data line. The pixel includes a first transistor, and a capacitor electrically connected between a gate electrode of the first transistor and an electrode of the first transistor. In a plan view, the data line extends in a second direction. The first power line extends in a first direction intersecting the second direction and overlaps the data line and the gate electrode of the first transistor. The second power line extends in the second direction, overlaps the data line, and overlaps the gate electrode of the first transistor.Type: ApplicationFiled: August 8, 2023Publication date: March 21, 2024Applicant: Samsung Display Co., LTD.Inventors: Sung Chan HWANG, Dong Hyun KIM, Chul Kyu KANG, Hey Jin SHIN, Seo Won CHOE, Chae Han HYUN

Publication number: 20100147326Abstract: An interdental cleaner with dental floss wherein the dental floss and the interdental cleaner are formed as a single body to increase the convenience of use. The present device makes alternative use of dental floss and interdental cleaner easier and increases convenience of use, by including a body having a handle part which a user grips, a holder fixing both ends of dental floss which are disposed at one end of the body and have a prescribed length, and an interdental cleaner mounted at the other end of the body. Since the interdental cleaner and dental floss of the present device are formed as a single body to be used alternatively according to the situation, the present device has an effect of improving convenience. Additionally, since it is possible to use the bristles of the interdental cleaner alternatively, the present device has an effect of increasing durability of the product.Type: ApplicationFiled: April 29, 2009Publication date: June 17, 2010Inventor: Sung Han Kang
