Publication number: 20240196635Abstract: A sensor-embedded display panel includes a light emitting element and a sensor which include separate portions of a first common auxiliary layer including a hole transport material and a second common auxiliary layer including an electron transport material. The sensor includes first and second semiconductor layers proximate to the first and second common auxiliary layers, respectively, and including a p-type semiconductor and a non-fullerene n-type semiconductor having a LUMO energy level deeper than that of the electron transport material, respectively. An insertion layer between the second semiconductor layer and the second common auxiliary layer includes a metal, a metal compound, or any combination thereof. A work function of the metal or a LUMO energy level of the metal compound is deeper or shallower than the LUMO energy level of the non-fullerene n-type semiconductor and the LUMO energy level of the electron transport material within less than about 1.3 eV, respectively.Type: ApplicationFiled: September 1, 2023Publication date: June 13, 2024Applicant: Samsung Electronics Co., Ltd.Inventors: Feifei FANG, Sungyoung YUN, Chul Joon HEO, Hyeong-Ju KIM, Kyung Bae PARK, Hwijoung SEO, Tae Jin CHOI

Publication number: 20240147744Abstract: A display panel may include a light emitting element including a light emitting layer and a sensor including a photosensitive layer on a substrate. The light emitting element and the sensor each may include respective portions of first and second common auxiliary layers, which may be continuous under and over the light emitting layer and the photosensitive layer. The first and second common auxiliary layers respectively may include a hole transport material and an electron transport material. The photosensitive layer may include first and second semiconductor layers close to the first and second common auxiliary layers, respectively. The first and second semiconductor layers respectively may include a p-type semiconductor and an n-type semiconductor. The second semiconductor layer may have an uneven surface facing the second common auxiliary layer and may have an average roughness (Rq) of greater than or equal to about 5 nm.Type: ApplicationFiled: September 22, 2023Publication date: May 2, 2024Applicant: Samsung Electronics Co., Ltd.Inventors: Sungyoung YUN, Hyeong-Ju KIM, Kyung Bae PARK, Jungyun WON, Bongsu KIM, Seongyong PARK, Jeong Il PARK

Publication number: 20240132021Abstract: An apparatus for controlling a discharge pressure of a fluid includes: a pump configured to suck the fluid through an inlet or to discharge the sucked fluid through an outlet; a distributor connected to the pump and to an injection nozzle provided by a sensor and configured to distribute the fluid discharged from the pump to the sensor; and a controller. The controller is configured to control the pump to operate selectively in accordance with detection of contamination of the sensor and to control operation of the distributor to be forcibly delayed during operation of the pump such that the fluid distributed to the sensor, when detected as being contaminated, is controlled to reach a selected required discharge pressure of different required discharge pressures selected in accordance with water amount information and a degree of contamination of the sensor.Type: ApplicationFiled: April 30, 2023Publication date: April 25, 2024Applicants: HYUNDAI MOTOR COMPANY, KIA CORPORATION, DY AUTO CORPORATIONInventors: Young Joon Shin, Chan Mook Choi, Gyu Won Han, Jong Min Park, Jin Hee Lee, Jong Wook Lee, Min Wook Park, Seong Jun Kim, Hyeong Jun Kim, Sun Ju Kim
