A circuit is disposed in the non-display area and electrically connected to the sensing electrodes through sensing lines. A peripheral electrode is disposed in the non-display area. In a display period, the circuit applies a common voltage to the sensing electrodes through the sensing lines. In a touch sensing period, the circuit transmits a touch sensing signal to the sensing electrodes through the sensing lines, and determines whether each of the sensing electrodes is touched based on capacitance of the sensing electrodes. In a stylus sensing period, the circuit transmits an uplink signal to the sensing electrodes and the peripheral electrode, and receives a downlink signal from the active stylus through the sensing electrodes, and determines a stylus location corresponding to the active stylus according to the downlink signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Touch-and-display device and sensing system with peripheral electrode for transmitting uplink signal","description":"The touch-and-display panel includes multiple sensing electrodes in the display area.
