Patent number: 11893156Abstract: A portable information handling system touchpad detects button inputs with a downward press at the touch surface that translates to a central button under the touch surface through a frame biased up by a central beam and plural biasing members. Downward presses at the touch surface off center translate towards the center of the frame to provide a central button input that is attributed with right, left and or center button push input values based upon detection of a location at which the downward press touch is sensed by the touch surface.Type: GrantFiled: October 25, 2021Date of Patent: February 6, 2024Assignee: Dell Products L.P.Inventors: Chin-Chung Wu, Hu Shih Chang, Chih-Ping Chang

Publication number: 20240023228Abstract: An LCD display module includes a polygon flexible printed circuit to produce a thinner display. The polygon flexible printed circuit connects a driver integrated circuit to a printed circuit board assembly and a glass substrate. The polygon flexible printed circuit has a narrow minor end connected to the glass substrate and a wider major end connected to the printed circuit board assembly. Because the polygon flexible printed circuit has different end widths, the polygon flexible printed circuit permits reduced spacing of electronic components in proximity of the narrower minor end. The LCD display module also includes a shielding can in physical communication with the printed circuit board assembly to reduce electromagnetic interference between the printed circuit board and the polygon flexible printed circuit.Type: ApplicationFiled: August 16, 2022Publication date: January 18, 2024Inventors: Tsung-Chin Cheng, Chin-Chung Wu, Hong-Ji Huang
