  • LCD apparatus with electrostatic discharge protection member
    Patent number: 7508465
    Abstract: An electronic device of LCD (liquid crystal display) having an electrostatic discharge (ESD) protection is disclosed. In device, a shielding metal cover has two saw-like flanges formed thereon to shield the electromagnetic wave interference the related circuit and to release electrostatic discharges (ESD) and to protect LCD module from ESD attack on suddenly.
    Type: Grant
    Filed: December 29, 2005
    Date of Patent: March 24, 2009
    Assignee: Qisda Corporation
    Inventors: San-Shan Hung, Tzong-Hsiang Lan
  • Keypad circuit with electrostatic discharge protection
    Patent number: 7425904
    Abstract: A keypad device having a circuit of electrostatic discharge (ESD) protection is disclosed. The circuit has n and m numbers of column conductive lines and row conductive lines formed on the print circuit board wherein at least one column or row conductive line is connected to the ground and the others are, respectively, connected to the data input terminals and data output terminals of the keypad encoder. The intersections between the column (row) line which is grounded and the row (column) lines are designed for those keys, which are readily attacked by ESD such as the side keys.
