Patent number: 11929032Abstract: A display device comprises a display panel which comprises scan lines, sensing lines, pixels electrically connected to each of the scan lines, and photo sensors electrically to each of the scan lines and the sensing lines, a scan driver which outputs scan signals to the scan lines according to a scan control signal, a timing controller which outputs the scan control signal to the scan driver, and a readout circuit which receives light sensing signals of the photo sensors from the sensing lines. The timing controller sets a frame frequency of the scan control signal to a first frame frequency in a first mode in which the display panel displays an image. The timing controller sets the frame frequency of the scan control signal to a second frame frequency in a second mode in which the photo sensors sense a fingerprint.Type: GrantFiled: August 15, 2022Date of Patent: March 12, 2024Assignee: SAMSUNG DISPLAY CO., LTD.Inventors: Hyun Dae Lee, Il Nam Kim, Seung Hyun Moon, Dong Wook Yang, Kang Bin Jo, Go Eun Cha

Patent number: 8867686Abstract: Disclosed herein is a high current solid target for radioisotope production at a cyclotron using a metal foam, and more specifically, a high current solid target for isotope production, which attaches a metal foam to the rear surface of the solid target plate. A high current solid target for isotope production including a metal foam according to the present invention may exhibit excellent cooling performances to increase the amount of proton beam current irradiated on the solid target compared to conventional planar-type solid targets. Because the irradiation of the increased proton beam current may increase the amount of an isotope produced per unit time and even an irradiation of proton beam in a short time may allow for production of a desired amount of an isotope, the solid target may be usefully used for production of medical cyclotron nuclides.Type: GrantFiled: June 23, 2010Date of Patent: October 21, 2014Assignee: Korea Atomic Energy Research InstituteInventors: Min Goo Hur, Seung Dae Yang, Sang Wook Kim, In Jong Kim, Sang Mu Choi

Publication number: 20090260971Abstract: Disclosed herein is a method of preparing a fluoroalkyl compound using radiation, including: mixing an alkyl compound having a leaving group with tetrabutylammonium fluoride (TBAF) in the presence of a reaction solvent at room temperature to form a mixed solution (step 1); and applying radiation to the mixed solution while stirring it to prepare a fluoroalkyl compound (step 2). The method of preparing a fluoroalkyl compound using radiation is advantageous in that fluoroalkyl compounds can be easily prepared in a short reaction time at room temperature, in that the method is safe because it is not required to use fluorine gas, which is harmful to the human body, in that the method can be usefully used to prepare fluoroalkyl compounds because the yield of fluoroalkyl compounds obtained using the method is higher than when using conventional SN2 reaction methods, and in that fluorine 18F, which is a radioactive isotope, can be easily introduced into alkyl compounds.Type: ApplicationFiled: October 2, 2008Publication date: October 22, 2009Applicant: Korea Atomic Energy Research InstituteInventors: Sang Wook Kim, Min Goo Hur, Seung Dae Yang, Kook Hyun Yu
