Publication number: 20240118182Abstract: A glass stress test method includes breaking a glass, analyzing a shape of a crack of a broken portion of the glass in a plan view, finding a breakage origin of the glass based on the shape of the crack in the plan view, analyzing a cross-section of the breakage origin, and calculating a stress of the glass based on a cross-sectional analysis result of the breakage origin. The stress of the glass is calculated as a value proportional to a floor constant defined by a condition of a floor surface disposed when the glass is broken.Type: ApplicationFiled: September 6, 2023Publication date: April 11, 2024Inventors: Min Ki KIM, Ji Hyun KO, Yong Kyu KANG, Jinsu NAM, Hyun Seung SEO, JUN HO LEE

Patent number: 7363948Abstract: A liquid crystal dispensing apparatus dispenses liquid crystal onto a substrate. The liquid crystal dispensing apparatus includes a frame, a table, at least one liquid crystal discharge device, and a liquid crystal amount inspecting portion. The table is installed on the frame to have the substrate to be mounted thereon. The liquid crystal discharge device adjustably discharges an amount of liquid crystal, and the liquid crystal amount inspecting portion inspects a liquid crystal dispensing amount by comparing an actual amount of liquid crystal discharged from the liquid crystal discharge device with a preset liquid crystal amount. The liquid crystal discharge device includes a piston to perform ascending motions to draw in the liquid crystal and descending motions to discharge the liquid crystal with an angle of at least a portion of the liquid crystal discharge device determining a magnitude of the ascending/descending motion to control an amount of liquid crystal discharged.Type: GrantFiled: January 24, 2006Date of Patent: April 29, 2008Assignee: LG.Philips LCD Co., Ltd.Inventors: Joung-Ho Ryu, Hyug-Jin Kweon, Hae-Joon Son, Kyu-Yong Bang, Joon-Young Kim, Man-Ho An, Yong-Kyu Seo
