  • Patent number: 7267555
    Abstract: A fan-out pattern having two or more fan-out sections is implemented between a driver IC and a display for reducing or eliminating the pathlength differences among the electrical conductors in the fan-out pattern. As such, some of the conductors between the driver IC and the display can have two or more zigzag swath widths. In a fan-out pattern having two fan-out sections, a first fan-out section widens the spacing, SI, between two adjacent conductors at the IC side to an intermediate spacing, SM, and a second fan-out section further widens the intermediate spacing SM to the spacing, SP, at the display side. With two fan-out sections, the first zigzag extension is implemented in some conductors between the IC side and the first fan-out section, and the second zigzag extension is implemented in some conductors between the first fan-out section and the second fan-out section.

  • Publication number: 20060076669
    Abstract: A deflectable probe for use in a thermometer. The deflectable probe is constituted by a bendable probe body and a hollow tip member secured thereto. Furthermore, a deflectable member includes a main portion disposed in the bendable probe body. When the bendable probe body is subjected to a force, deformation of the main portion occurs. In particular, the deformation cannot be undone by a return force from the bendable probe body when the applied force is removed, so that the bendable probe body is sustained in a bent form. A space is formed between the hollow pipe and the main portion of the deflectable member for deformation of the main portion to prevent the deflectable member being easily pushed into the hollow cavity and avoid the lead wires being easily cut off.
