Problems solved by technology

Because the potential of the lighthouse signal received by the stylus 110 from the capacitor A is greatly reduced from its own ground potential, the potential difference becomes very small, so the strength of the lighthouse signal detected by the stylus will become very weak

Abstract

The present application provides a stylus for receiving a wireless radio frequency signal emitted from a touch panel or screen. The stylus includes a rod covered by dielectric material for user's handling; an electrode for receiving the wireless radio frequency signal; and a receiving circuit coupled to the electrode, wherein the receiving circuit is placed inside the rod.

Description

technical field [0001] The present invention relates to a touch electronic system, in particular to a stylus and its electronic system. Background technique [0002] The stylus can detect electrical signals from the touch panel / screen to perform certain functions, and the electrical signals from the touch panel can be called beacons. The lighthouse signal can be sent by at least one electrode of the touch panel. In some examples, the touch panel can emit a beacon signal through multiple parallel electrodes for detection by the stylus. [0003] In one example, the stylus can use the lighthouse signal to perform the wake-up function. Since the stylus may use an electrical energy storage device to provide power, the stylus may often enter a power saving mode in order to save energy consumption. When the stylus detects the signal from the lighthouse, it can enter into a more power-consuming working mode. [0004] In another example, the stylus can use the lighthouse signal t...
