  • Apparatus and method for preventing false touches in touch screen systems
    Patent number: 9229576
    Abstract: A method comprises during a frame period finding a first EFT noise influenced sensor of a touch screen panel, determining whether the first EFT noise influenced sensor is located at a last transmitting/driving line of the touch screen panel, designating the frame period as a noise influenced frame period using an absolute value threshold if the first EFT noise influenced sensor is not located at the last transmitting/driving line and designating the frame period as the noise influenced frame period using a percentage threshold if the first EFT noise influenced sensor is located at the last transmitting/driving line.
    Type: Grant

    Date of Patent: January 5, 2016
    Assignee: STMicroelectronics Asia Pacific PTE Ltd
    Inventors: HonSiong Ng, Praveesh Chandran, Mythreyi Nagarajan, Ravi Bhatia

  • ITO PATTERN FOR CAPACITIVE TOUCHSCREEN APPLICATIONS
    Publication number: 20140035602
    Abstract: A capacitive sensing structure is formed from first electrically conductive sensor structures electrically coupled to each other in a first direction, and second electrically conductive sensor structures electrically coupled to each other in a second direction. Each first electrically conductive sensor structure includes a first diamond-shaped central region with electrically coupled first finger structures extending away therefrom. Each second electrically conductive sensor structure includes a second diamond-shaped central region with electrically conducting second finger structures extending away therefrom. Each second finger structure extends between two adjacent ones of the first finger structures. Floating structures may be included within an opening formed in the first diamond shaped central region. Floating structures may further be included between the first and second finger structures.
