  • Patent number: 10126862
    Abstract: An operation device includes an operation plate, an electrode, a determination portion, an output portion, a dial, a dummy electrode, a for-dummy determination portion, and a disablement portion. The operation plate includes an operation surface that is contact-operated by an operator's fingertip. The determination portion determines whether the contact-operation is performed based on an amount of capacitance change between the fingertip and the electrode. The output portion outputs a predetermined command signal on the condition that the contact-operation is determined to be performed. When it is determined by the dummy electrode and the for-dummy determination portion that an operator's hand is placed at a position where a dial is operable, the disablement portion prohibits an output of the command signal or disables the outputted command signal.

  • Patent number: 10073569
    Abstract: A polarizer integrated with conductive material and a process for forming a polarizer integrated with conductive material are disclosed. A polarizer can be integrated with conductive material to form a portion of a touch sensor panel. In one example, a layer of conductive film forming either the row or column traces can be patterned on a surface of a substrate in the polarizer. In another example, the layer of conductive film can be patterned on a viewing angle compensation film of the polarizer. One or more of the polarizer's polarizing layer, protective substrates or viewing angle compensation film can act as a dielectric between the conductive material forming the rows and column traces in the stack-up. As a result, the clear polymer spacer acting as a dielectric in touch panels can be removed, reducing the thickness of the touch screen stack-up.
