  • Publication number: 20240086014
    Abstract: An electronic device may have a display with touch sensors. One or more shielding layers may be interposed between the display and the touch sensors. The shielding layers may include shielding structures such as a conductive mesh structure and/or a transparent conductive film. The shielding structures may be actively driven or passively biased. In the active driving scheme, one or more inverting circuits may receive a noise signal from a cathode layer in the display and/or from the shielding structures, invert the received noise signal, and drive the inverted noise signal back onto the shielding structures to prevent any noise from the display from negatively impacting the performance of the touch sensors. In the passive biasing scheme, the shielding structures may be biased to a power supply voltage.

  • Patent number: 11892669
    Abstract: A polarizing plate and a display device including the same. The polarizing plate includes a retardation layer exhibiting ultraviolet blocking characteristics even in a state where the retardation layer does not include any ultraviolet absorber or light stabilizer. The polarizing plate can be used alone or in combination with an appropriate sunscreen or a light stabilizer as needed to selectively block ultraviolet rays in a region requiring blocking, without affecting display performance, such as color senses and image quality, of a display device. The polarizing plate can also be formed with a small thickness without requiring a separate ultraviolet blocking layer, and also has excellent durability, because the polarizing plate exhibits a certain ultraviolet blocking property even in the absence of an ultraviolet absorber or light stabilizer.
