  • Publication number: 20230376132
    Abstract: An information handling system stylus transmits a wireless signal at a writing tip to enhance touch detection of the writing tip by a touchscreen display and receives wireless signals from the touchscreen display at a receiving antenna. To enhance control of wireless energy distributed at the writing tip, the receiving antenna is selectively coupled to the writing tip, such as by transitioning from a float of the receiving antenna to an interface with the stylus power source at transmit by the writing tip. Charge at the receiving antenna helps to shape the energy distribution from the writing tip, such as to match the energy distribution of other styluses in use at the touchscreen display.

  • Patent number: 11662861
    Abstract: An information handling system presents visual images at a display that includes a display panel having a capacitive touch detection surface supported by an indium tin oxide layer disposed between a front layer, such as polarizer, and a display cell. To prevent excessive charge build up associated with the capacitive touch detection surface, a conductive ink is applied at the display panel perimeter and interfaced with a ground at the rear side of the display panel. In one example embodiment, a non-conductive ink insulates the conductive ink from the display panel except as desired to transfer excess charge from the indium tin oxide layer. The conductive ink may interface directly with the indium tin oxide layer or indirectly through a second non-conductive ink having greater conductivity than the insulative non-conductive ink.
