— 1 min read

The inventors Chen, Chun-Hung, Shih, Wei-Lun, and Tang, Yu-Ying from Taipei City, Hsinchu City, and Taoyuan City, Taiwan, respectively, have filed a patent application (20250306699) with the United States Patent and Trademark Office on June 4, 2024, for an electronic device that integrates touch and display functions. The application is assigned to Novatek Microelectronics Corp. in Hsinchu, Taiwan. The device aims to reduce interference between signals applied to display and touch, thereby improving the signal-to-noise ratio (SNR) of the signal in the touch display device.

Key Takeaways:

  • The patent application proposes a touch and display integrated circuit (TDC) that drives a touch display device by reducing interference between signals applied to display and touch.
  • The TDC consists of a first display driving pad set, a second display driving pad set, multiple first touch pad sets, and multiple second touch pad sets.
  • The first touch pad sets and the second touch pad sets are disposed between the first display driving pad set and the second display driving pad set, allowing for the reduction of interference between signals applied to display and touch.
  • The touch circuit comprises multiple transmitting electrodes and multiple receiving electrodes, with the first touch pad sets connected to the transmitting electrodes and the second touch pad sets connected to the receiving electrodes.
  • The proposed solution enables the touch and display integrated circuit and the touch display device to reduce interference between signals applied to display and touch, thereby improving the signal-to-noise ratio (SNR) of the signal in the touch display device.

Statistics:

  • The patent application was filed on June 4, 2024.
  • The patent application is assigned to Novatek Microelectronics Corp.
  • The device aims to reduce interference between signals applied to display and touch, thereby improving the signal-to-noise ratio (SNR) of the signal in the touch display device.
  • The touch and display integrated circuit consists of 5 sets of display driving pads, 7 sets of touch pads, and a touch circuit with 3 types of leading wires.
  • The device is applicable to touch display devices, such as mobile phones, tablets, and laptops.
