Publication number: 20240241185Abstract: This disclosure provides an estimation method applied to a state of health of a battery, which executes a recharging to a battery when a battery voltage is lower than a threshold voltage. During the recharging, a battery state of health estimation procedure is performed from a first depth of discharge detection point to a second depth of discharge detection point. During the battery state of health estimation procedure, a voltage difference between a current battery voltage and an initial open-circuit voltage is accumulated over time from the first depth of discharge detection point to the second depth of discharge detection point to obtain an accumulation of current sampled voltage difference. An accumulation of estimated DC internal resistances can be equivalently obtained by the accumulation of current sampled voltage difference. Afterwards, the state of health of the battery can be determined based on the accumulation of estimated DC internal resistance.Type: ApplicationFiled: July 11, 2023Publication date: July 18, 2024Inventors: Wen-Fan Chang, Chun-Chieh Li, Shih-Fa Hung, Jian-Min Chen

Publication number: 20230341305Abstract: A shear test is conducted on an interconnect bond formed on a surface of an electronic device by first determining a profile of the surface, and based on the determined profile, determining a shearing path which is at a substantially constant distance from the profile of the surface for a shear test tool to conduct the shear test on the interconnect bond. The shear test tool is then guided to move along the determined shearing path to measure a shear force of the interconnect bond.Type: ApplicationFiled: April 21, 2023Publication date: October 26, 2023Inventors: Keng Yew SONG, Zui Hong LEE, Jian Min CHEN, Mow Huat GOH, Kien Kia TAN

Publication number: 20230137302Abstract: An apparatus for calibrating a shear test tool utilizes a resilient pivot mechanism to improve accuracy and reliability of the force calibration. The apparatus includes a fixed element, a pivotable element configured to be rotatable relative to the fixed element, and a resilient pivot mechanism coupled between the fixed element and the pivotable element to form a pivot. The pivotable element is rotatable about the pivot to lift a weight coupled to the pivotable element when the shear test tool applies a force on the pivotable element in order to rotate the pivotable element and lift the weight.

Patent number: 9217896Abstract: A liquid crystal display comprises two parallel spaced substrates and a liquid crystal layer with negative dielectric anisotropy interposed between the substrates. The ratio d/p, the cell gap d between the substrates to the pitch p of the liquid crystal layer, is equal to or less than 0.3, and the retardation value ?n*d may be in the range of 0.25-0.4. In absence of electric field, the liquid crystal molecules are arranged vertically to the substrates, and when the sufficient electric field is applied, the liquid crystal molecules are parallel to the substrates and twisted by 90° from one substrate to the other.Type: GrantFiled: June 30, 2014Date of Patent: December 22, 2015Assignee: SAMSUNG DISPLAY CO., LTD.Inventors: Jae-Jin Lyu, Hea-Ri Lee, Kyeong-Hyeon Kim, Jian-Min Chen

Patent number: 9041891Abstract: Apertures are formed in the common electrode or in the pixel electrode of a liquid crystal display to form a fringe field. Storage capacitor electrodes are formed at the position corresponding to the apertures to prevent the light leakage due to the disclination caused by the fringe field. The apertures extend horizontally, vertically or obliquely. The apertures in adjacent pixel regions may have different directions to widen the viewing angle.Type: GrantFiled: March 3, 2014Date of Patent: May 26, 2015Assignee: SAMSUNG DISPLAY CO., LTD.Inventors: Jae-Jin Lyu, Kyeong Hyeon Kim, Hea-Ri Lee, Jian-Min Chen
