Latest Patents

One of Hongwoo Lee's latest patents focuses on shielding for electronic device displays with touch sensors. This invention involves the integration of one or more shielding layers between the display and the touch sensors. The shielding layers may consist of various structures, including a conductive mesh structure and a transparent conductive film. These shielding structures can be actively driven or passively biased. In the active driving scheme, inverting circuits receive noise signals from the cathode layer in the display or from the shielding structures. They invert the received noise signals and drive the inverted signals back onto the shielding structures. This process prevents any noise from negatively impacting the performance of the touch sensors. In the passive biasing scheme, the shielding structures are biased to a power supply voltage, further enhancing the display's performance.
