  • Publication number: 20250085810
    Abstract: A display panel and a display device are provided. By means of a shielding structure with a floating potential provided over a projection of a sensing read line, when an electrical signal is transmitted on the sensing read line and a pixel data line, a shielding electric field will be formed between the shielding structure and the sensing read line. The presence of the shielding electric field can reduce capacitance between the sensing read line and adjacent pixel data line and effectively improve a signal-to-noise ratio during signal transmission.
